FINDINGS SECTION (2 findings)
-------------------------------------------------------------------------------
1- SQL Profile Finding (see explain plans section below)
--------------------------------------------------------
为此语句找到了性能更好的执行计划 2。选择以下 SQL 概要文件之一进行实施。
由于 SQL profile 可能造成了显著的 I/O 时间缩短, 因此未自动创建它。
Recommendation (estimated benefit: 67.21%)
------------------------------------------
- 考虑接受推荐的 SQL 概要文件。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285327, task_owner =>
'SYS', replace => TRUE);
Validation results
------------------
已对 SQL profile 进行测试, 方法为执行其计划和原始计划并测量与计划相对应的执行统计信息。如果其中一个计划运行在很短的时间内就完成,
则另一计划可能只执行了一部分。
Original Plan With SQL Profile % Improved

Completion Status: COMPLETE COMPLETE
Elapsed Time (s): 21.600848 17.279351 20 %

Rows Processed: 401 401
Fetches: 401 401
Executions: 1 1
Recommendation (estimated benefit: 99.97%)
------------------------------------------
- 考虑接受建议的 SQL 概要文件, 以便对此语句使用并行执行。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285327, task_owner =>
'SYS', replace => TRUE, profile_type => DBMS_SQLTUNE.PX_PROFILE);
与 DOP 288 并行执行此查询会使 SQL 概要文件计划上的响应时间缩短 99.34%。但是, 启用并行执行时要付出一些代价。它将增加语句的资源消耗
(预计为 89.93%), 这会导致系统吞吐量降低。此外, 由于在非常短的持续时间内消耗了这些资源, 因此如果没有足够可用的硬件容量,
并发语句的响应时间将受到负面影响。
The following data shows some sampled statistics for this SQL from the past
week and projected weekly values when parallel execution is enabled.
Past week sampled statistics for this SQL

Number of executions 0
Percent of total activity 0
Percent of samples with #Active Sessions > 2*CPU 0
Weekly DB time (in sec) 0
Projected statistics with Parallel Execution
--------------------------------------------
Weekly DB time (in sec) 0
2- Index Finding (see explain plans section below)
--------------------------------------------------
通过创建一个或多个索引可以改进此语句的执行计划。
Recommendation (estimated benefit: 99.99%)
------------------------------------------
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_0001000D on JC800.APMACTUALSEQDATAITEM(TO_CHAR("SC
ANTIME",'yyyy-MM-dd HH24:mi:ss'));
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_0001000E on JC800.BDMWORKCENTERHEADER("PLANT","OBJ
ECTID");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_0001000F on JC800.JITMANPLANPAR("CLIENT","PROPORTI
ONFINGER");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010010 on JC800.JITSHOPKBGATHER("CLIENT","STRATE
BATCHNO","STRATEGY");
Rationale
---------
创建推荐的索引可以显著地改进此语句的执行计划。但是, 使用典型的 SQL 工作量运行 "访问指导"
可能比单个语句更可取。通过这种方法可以获得全面的索引建议案, 包括计算索引维护的开销和附加的空间消耗。

FINDINGS SECTION (2 findings)
-------------------------------------------------------------------------------
1- SQL Profile Finding (see explain plans section below)
--------------------------------------------------------
为此语句找到了性能更好的执行计划 2。选择以下 SQL 概要文件之一进行实施。
SQL profile 未自动创建, 因为自动创建功能已禁用。请将任务参数 ACCEPT_SQL_PROFILES 设置为 TRUE 以启用自动创建功能。
Recommendation (estimated benefit: 76.13%)
------------------------------------------
- 考虑接受推荐的 SQL 概要文件。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285360, task_owner =>
'SYS', replace => TRUE);
Validation results
------------------
已对 SQL profile 进行测试, 方法为执行其计划和原始计划并测量与计划相对应的执行统计信息。如果其中一个计划运行在很短的时间内就完成,
则另一计划可能只执行了一部分。
Original Plan With SQL Profile % Improved
------------- ---------------- ----------
Completion Status: PARTIAL COMPLETE
Elapsed Time (s): 30.62509 1.220906 96.01 %
CPU Time (s): 30.497364 1.200818 96.06 %
User I/O Time (s): 0 .00891

Physical Write Bytes: 0 0
Rows Processed: 0 607
Fetches: 0 607
Executions: 0 1
Recommendation (estimated benefit: 99.98%)
------------------------------------------
- 考虑接受建议的 SQL 概要文件, 以便对此语句使用并行执行。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285360, task_owner =>
'SYS', replace => TRUE, profile_type => DBMS_SQLTUNE.PX_PROFILE);
与 DOP 288 并行执行此查询会使 SQL 概要文件计划上的响应时间缩短 99.34%。但是, 启用并行执行时要付出一些代价。它将增加语句的资源消耗
(预计为 89.59%), 这会导致系统吞吐量降低。此外, 由于在非常短的持续时间内消耗了这些资源, 因此如果没有足够可用的硬件容量,
并发语句的响应时间将受到负面影响。
The following data shows some sampled statistics for this SQL from the past
week and projected weekly values when parallel execution is enabled.
Past week sampled statistics for this SQL
-----------------------------------------
Number of executions 0
Percent of total activity 0
Percent of samples with #Active Sessions > 2*CPU 0
Weekly DB time (in sec) 0
Projected statistics with Parallel Execution
--------------------------------------------
Weekly DB time (in sec) 0
2- Index Finding (see explain plans section below)
--------------------------------------------------
通过创建一个或多个索引可以改进此语句的执行计划。
Recommendation (estimated benefit: 99.99%)
------------------------------------------
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010018 on JC800.APMACTUALSEQDATAITEM(TO_CHAR("SC
ANTIME",'yyyy-MM-dd HH24:mi:ss'));
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010019 on JC800.JITMANPLANPAR("CLIENT","PROPORTI
ONFINGER");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_0001001A on JC800.BDMWORKCENTERHEADER("PLANT","OBJ
ECTID");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_0001001B on JC800.JITSHOPKBGATHER("CLIENT","STRATE
BATCHNO","STRATEGY");
Rationale
---------
创建推荐的索引可以显著地改进此语句的执行计划。但是, 使用典型的 SQL 工作量运行 "访问指导"
可能比单个语句更可取。通过这种方法可以获得全面的索引建议案, 包括计算索引维护的开销和附加的空间消耗。

FINDINGS SECTION (2 findings)
-------------------------------------------------------------------------------
1- SQL Profile Finding (see explain plans section below)
--------------------------------------------------------
为此语句找到了性能更好的执行计划 2。选择以下 SQL 概要文件之一进行实施。
SQL profile 未自动创建, 因为自动创建功能已禁用。请将任务参数 ACCEPT_SQL_PROFILES 设置为 TRUE 以启用自动创建功能。
Recommendation (estimated benefit: 69.14%)
------------------------------------------
- 考虑接受推荐的 SQL 概要文件。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285363, task_owner =>
'SYS', replace => TRUE);
Validation results
------------------
已对 SQL profile 进行测试, 方法为执行其计划和原始计划并测量与计划相对应的执行统计信息。如果其中一个计划运行在很短的时间内就完成,
则另一计划可能只执行了一部分。
Original Plan With SQL Profile % Improved
------------- ---------------- ----------
Completion Status: COMPLETE COMPLETE
Elapsed Time (s): 23.412212 1.388229 94.07 %
CPU Time (s): 23.384445 1.373792 94.12 %

Executions: 1 1
Recommendation (estimated benefit: 99.96%)
------------------------------------------
- 考虑接受建议的 SQL 概要文件, 以便对此语句使用并行执行。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285363, task_owner =>
'SYS', replace => TRUE, profile_type => DBMS_SQLTUNE.PX_PROFILE);
与 DOP 288 并行执行此查询会使 SQL 概要文件计划上的响应时间缩短 99.34%。但是, 启用并行执行时要付出一些代价。它将增加语句的资源消耗
(预计为 89.63%), 这会导致系统吞吐量降低。此外, 由于在非常短的持续时间内消耗了这些资源, 因此如果没有足够可用的硬件容量,
并发语句的响应时间将受到负面影响。
The following data shows some sampled statistics for this SQL from the past
week and projected weekly values when parallel execution is enabled.

Weekly DB time (in sec) 0
2- Index Finding (see explain plans section below)
--------------------------------------------------
通过创建一个或多个索引可以改进此语句的执行计划。
Recommendation (estimated benefit: 99.99%)
------------------------------------------
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010020 on JC800.APMACTUALSEQDATAITEM(TO_CHAR("SC
ANTIME",'yyyy-MM-dd HH24:mi:ss'));
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010021 on JC800.BDMWORKCENTERHEADER("PLANT","OBJ
ECTID");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010022 on JC800.JITMANPLANPAR("CLIENT","PROPORTI
ONFINGER");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010023 on JC800.JITSHOPKBGATHER("CLIENT","STRATE
BATCHNO","STRATEGY");
Rationale
---------
创建推荐的索引可以显著地改进此语句的执行计划。但是, 使用典型的 SQL 工作量运行 "访问指导"
可能比单个语句更可取。通过这种方法可以获得全面的索引建议案, 包括计算索引维护的开销和附加的空间消耗。

Recommendation (estimated benefit: 99.99%)
------------------------------------------
- 考虑接受建议的 SQL 概要文件, 以便对此语句使用并行执行。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285377, task_owner =>
'SYS', replace => TRUE, profile_type => DBMS_SQLTUNE.PX_PROFILE);
与 DOP 288 并行执行此查询会使 SQL 概要文件计划上的响应时间缩短 99.47%。但是, 启用并行执行时要付出一些代价。它将增加语句的资源消耗
(预计为 51.33%), 这会导致系统吞吐量降低。此外, 由于在非常短的持续时间内消耗了这些资源, 因此如果没有足够可用的硬件容量,
并发语句的响应时间将受到负面影响。

2- Index Finding (see explain plans section below)
--------------------------------------------------
通过创建一个或多个索引可以改进此语句的执行计划。
Recommendation (estimated benefit: 99.99%)
------------------------------------------
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010028 on JC800.APMACTUALSEQDATAITEM(TO_CHAR("SC
ANTIME",'yyyy-MM-dd HH24:mi:ss'));
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010029 on JC800.BDMWORKCENTERHEADER("PLANT","OBJ
ECTID");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_0001002A on JC800.JITMANPLANPAR("CLIENT","PROPORTI
ONFINGER");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_0001002B on JC800.JITSHOPKBGATHER("CLIENT","STRATE
BATCHNO","STRATEGY");
Rationale
---------
创建推荐的索引可以显著地改进此语句的执行计划。但是, 使用典型的 SQL 工作量运行 "访问指导"
可能比单个语句更可取。通过这种方法可以获得全面的索引建议案, 包括计算索引维护的开销和附加的空间消耗。

FINDINGS SECTION (2 findings)
-------------------------------------------------------------------------------
1- SQL Profile Finding (see explain plans section below)
--------------------------------------------------------
为此语句找到了性能更好的执行计划 2。选择以下 SQL 概要文件之一进行实施。
SQL profile 未自动创建, 因为经验证可获得的收益太少。
Recommendation (estimated benefit: 49.59%)
------------------------------------------
- 考虑接受推荐的 SQL 概要文件。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285380, task_owner =>
'SYS', replace => TRUE);
Validation results
------------------
已对 SQL profile 进行测试, 方法为执行其计划和原始计划并测量与计划相对应的执行统计信息。如果其中一个计划运行在很短的时间内就完成,
则另一计划可能只执行了一部分。
Original Plan With SQL Profile % Improved
------------- ---------------- ----------
Completion Status: COMPLETE COMPLETE
Elapsed Time (s): 13.490854 1.078417 92 %
CPU Time (s): 13.476952 1.077836 92 %

Rows Processed: 264 264
Fetches: 264 264
Executions: 1 1
Recommendation (estimated benefit: 99.96%)
------------------------------------------
- 考虑接受建议的 SQL 概要文件, 以便对此语句使用并行执行。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285380, task_owner =>
'SYS', replace => TRUE, profile_type => DBMS_SQLTUNE.PX_PROFILE);
与 DOP 288 并行执行此查询会使 SQL 概要文件计划上的响应时间缩短 99.47%。但是, 启用并行执行时要付出一些代价。它将增加语句的资源消耗
(预计为 51.64%), 这会导致系统吞吐量降低。此外, 由于在非常短的持续时间内消耗了这些资源, 因此如果没有足够可用的硬件容量,
并发语句的响应时间将受到负面影响。
The following data shows some sampled statistics for this SQL from the past
week and projected weekly values when parallel execution is enabled.
Past week sampled statistics for this SQL
-----------------------------------------
Number of executions 0
Percent of total activity 0
Percent of samples with #Active Sessions > 2*CPU 0
Weekly DB time (in sec) 0
Projected statistics with Parallel Execution
--------------------------------------------
Weekly DB time (in sec) 0
2- Index Finding (see explain plans section below)
--------------------------------------------------
通过创建一个或多个索引可以改进此语句的执行计划。
Recommendation (estimated benefit: 99.99%)
------------------------------------------
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_0001002E on JC800.APMACTUALSEQDATAITEM(TO_CHAR("SC
ANTIME",'yyyy-MM-dd HH24:mi:ss'));
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_0001002F on JC800.BDMWORKCENTERHEADER("PLANT","OBJ
ECTID");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010030 on JC800.JITMANPLANPAR("CLIENT","PROPORTI
ONFINGER");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010031 on JC800.JITSHOPKBGATHER("CLIENT","STRATE
BATCHNO","STRATEGY");
Rationale
---------
创建推荐的索引可以显著地改进此语句的执行计划。但是, 使用典型的 SQL 工作量运行 "访问指导"
可能比单个语句更可取。通过这种方法可以获得全面的索引建议案, 包括计算索引维护的开销和附加的空间消耗。

FINDINGS SECTION (2 findings)
-------------------------------------------------------------------------------
1- SQL Profile Finding (see explain plans section below)
--------------------------------------------------------
为此语句找到了性能更好的执行计划 2。选择以下 SQL 概要文件之一进行实施。
SQL profile 未自动创建, 因为自动创建功能已禁用。请将任务参数 ACCEPT_SQL_PROFILES 设置为 TRUE 以启用自动创建功能。
Recommendation (estimated benefit: 66.72%)
------------------------------------------
- 考虑接受推荐的 SQL 概要文件。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285381, task_owner =>
'SYS', replace => TRUE);
Validation results
------------------
已对 SQL profile 进行测试, 方法为执行其计划和原始计划并测量与计划相对应的执行统计信息。如果其中一个计划运行在很短的时间内就完成,
则另一计划可能只执行了一部分。
Original Plan With SQL Profile % Improved
------------- ---------------- ----------
Completion Status: COMPLETE COMPLETE
Elapsed Time (s): 21.793969 1.391961 93.61 %
CPU Time (s): 21.757693 1.390789 93.6 %

Rows Processed: 401 401
Fetches: 401 401
Executions: 1 1
Recommendation (estimated benefit: 99.98%)
------------------------------------------
- 考虑接受建议的 SQL 概要文件, 以便对此语句使用并行执行。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285381, task_owner =>
'SYS', replace => TRUE, profile_type => DBMS_SQLTUNE.PX_PROFILE);
与 DOP 288 并行执行此查询会使 SQL 概要文件计划上的响应时间缩短 99.47%。但是, 启用并行执行时要付出一些代价。它将增加语句的资源消耗
(预计为 51.76%), 这会导致系统吞吐量降低。此外, 由于在非常短的持续时间内消耗了这些资源, 因此如果没有足够可用的硬件容量,
并发语句的响应时间将受到负面影响。
The following data shows some sampled statistics for this SQL from the past
week and projected weekly values when parallel execution is enabled.
Past week sampled statistics for this SQL
-----------------------------------------
Number of executions 0
Percent of total activity 0
Percent of samples with #Active Sessions > 2*CPU 0
Weekly DB time (in sec) 0
Projected statistics with Parallel Execution
--------------------------------------------
Weekly DB time (in sec) 0
2- Index Finding (see explain plans section below)
--------------------------------------------------
通过创建一个或多个索引可以改进此语句的执行计划。
Recommendation (estimated benefit: 99.99%)
------------------------------------------
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010032 on JC800.APMACTUALSEQDATAITEM(TO_CHAR("SC
ANTIME",'yyyy-MM-dd HH24:mi:ss'));
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010033 on JC800.BDMWORKCENTERHEADER("PLANT","OBJ
ECTID");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010034 on JC800.JITMANPLANPAR("CLIENT","PROPORTI
ONFINGER");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010035 on JC800.JITSHOPKBGATHER("CLIENT","STRATE
BATCHNO","STRATEGY");
Rationale
---------
创建推荐的索引可以显著地改进此语句的执行计划。但是, 使用典型的 SQL 工作量运行 "访问指导"
可能比单个语句更可取。通过这种方法可以获得全面的索引建议案, 包括计算索引维护的开销和附加的空间消耗。

FINDINGS SECTION (2 findings)
-------------------------------------------------------------------------------
1- SQL Profile Finding (see explain plans section below)
--------------------------------------------------------
为此语句找到了性能更好的执行计划 2。选择以下 SQL 概要文件之一进行实施。
SQL profile 未自动创建, 因为经验证可获得的收益太少。
Recommendation (estimated benefit: 49.02%)
------------------------------------------
- 考虑接受推荐的 SQL 概要文件。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285384, task_owner =>
'SYS', replace => TRUE);
Validation results
------------------
已对 SQL profile 进行测试, 方法为执行其计划和原始计划并测量与计划相对应的执行统计信息。如果其中一个计划运行在很短的时间内就完成,
则另一计划可能只执行了一部分。
Original Plan With SQL Profile % Improved
------------- ---------------- ----------
Completion Status: COMPLETE COMPLETE
Elapsed Time (s): 15.089957 1.456678 90.34 %
CPU Time (s): 15.034715 1.44778 90.37 %
User I/O Time (s): 0 0

Physical Write Bytes: 0 0
Rows Processed: 261 261
Fetches: 261 261
Executions: 1 1
Recommendation (estimated benefit: 99.98%)
------------------------------------------
- 考虑接受建议的 SQL 概要文件, 以便对此语句使用并行执行。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285384, task_owner =>
'SYS', replace => TRUE, profile_type => DBMS_SQLTUNE.PX_PROFILE);
与 DOP 288 并行执行此查询会使 SQL 概要文件计划上的响应时间缩短 99.48%。但是, 启用并行执行时要付出一些代价。它将增加语句的资源消耗
(预计为 50.86%), 这会导致系统吞吐量降低。此外, 由于在非常短的持续时间内消耗了这些资源, 因此如果没有足够可用的硬件容量,
并发语句的响应时间将受到负面影响。
The following data shows some sampled statistics for this SQL from the past
week and projected weekly values when parallel execution is enabled.
Past week sampled statistics for this SQL
-----------------------------------------
Number of executions 0
Percent of total activity 0
Percent of samples with #Active Sessions > 2*CPU 0
Weekly DB time (in sec) 0
Projected statistics with Parallel Execution
--------------------------------------------
Weekly DB time (in sec) 0
2- Index Finding (see explain plans section below)
--------------------------------------------------
通过创建一个或多个索引可以改进此语句的执行计划。
Recommendation (estimated benefit: 99.99%)
------------------------------------------
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010036 on JC800.APMACTUALSEQDATAITEM(TO_CHAR("SC
ANTIME",'yyyy-MM-dd HH24:mi:ss'));
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010037 on JC800.JITMANPLANPAR("CLIENT","PROPORTI
ONFINGER");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010038 on JC800.BDMWORKCENTERHEADER("PLANT","OBJ
ECTID");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010039 on JC800.JITSHOPKBGATHER("CLIENT","STRATE
BATCHNO","STRATEGY");
Rationale
---------
创建推荐的索引可以显著地改进此语句的执行计划。但是, 使用典型的 SQL 工作量运行 "访问指导"
可能比单个语句更可取。通过这种方法可以获得全面的索引建议案, 包括计算索引维护的开销和附加的空间消耗。

FINDINGS SECTION (2 findings)
-------------------------------------------------------------------------------
1- SQL Profile Finding (see explain plans section below)
--------------------------------------------------------
为此语句找到了性能更好的执行计划 2。选择以下 SQL 概要文件之一进行实施。
SQL profile 未自动创建, 因为自动创建功能已禁用。请将任务参数 ACCEPT_SQL_PROFILES 设置为 TRUE 以启用自动创建功能。
Recommendation (estimated benefit: 71.16%)
------------------------------------------
- 考虑接受推荐的 SQL 概要文件。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285386, task_owner =>
'SYS', replace => TRUE);
Validation results
------------------
已对 SQL profile 进行测试, 方法为执行其计划和原始计划并测量与计划相对应的执行统计信息。如果其中一个计划运行在很短的时间内就完成,
则另一计划可能只执行了一部分。
Original Plan With SQL Profile % Improved
------------- ---------------- ----------
Completion Status: COMPLETE COMPLETE
Elapsed Time (s): 25.30354 1.317776 94.79 %
CPU Time (s): 25.226165 1.305803 94.82 %
User I/O Time (s): 0 0
Buffer Gets: 2428742 700955 71.13 %
Physical Read Requests: 0 0
Physical Write Requests: 0 0
Physical Read Bytes: 0 0
Physical Write Bytes: 0 0
Rows Processed: 456 456
Fetches: 456 456
Executions: 1 1
Recommendation (estimated benefit: 99.99%)
------------------------------------------
- 考虑接受建议的 SQL 概要文件, 以便对此语句使用并行执行。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285386, task_owner =>
'SYS', replace => TRUE, profile_type => DBMS_SQLTUNE.PX_PROFILE);
与 DOP 288 并行执行此查询会使 SQL 概要文件计划上的响应时间缩短 99.34%。但是, 启用并行执行时要付出一些代价。它将增加语句的资源消耗
(预计为 89.94%), 这会导致系统吞吐量降低。此外, 由于在非常短的持续时间内消耗了这些资源, 因此如果没有足够可用的硬件容量,
并发语句的响应时间将受到负面影响。
The following data shows some sampled statistics for this SQL from the past
week and projected weekly values when parallel execution is enabled.
Past week sampled statistics for this SQL
-----------------------------------------
Number of executions 0
Percent of total activity 0
Percent of samples with #Active Sessions > 2*CPU 0
Weekly DB time (in sec) 0
Projected statistics with Parallel Execution
--------------------------------------------
Weekly DB time (in sec) 0
2- Index Finding (see explain plans section below)
--------------------------------------------------
通过创建一个或多个索引可以改进此语句的执行计划。
Recommendation (estimated benefit: 99.99%)
------------------------------------------
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_0001003A on JC800.APMACTUALSEQDATAITEM(TO_CHAR("SC
ANTIME",'yyyy-MM-dd HH24:mi:ss'));
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_0001003B on JC800.BDMWORKCENTERHEADER("PLANT","OBJ
ECTID");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_0001003C on JC800.JITMANPLANPAR("CLIENT","PROPORTI
ONFINGER");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_0001003D on JC800.JITSHOPKBGATHER("CLIENT","STRATE
BATCHNO","STRATEGY");
Rationale
---------
创建推荐的索引可以显著地改进此语句的执行计划。但是, 使用典型的 SQL 工作量运行 "访问指导"
可能比单个语句更可取。通过这种方法可以获得全面的索引建议案, 包括计算索引维护的开销和附加的空间消耗。

FINDINGS SECTION (2 findings)
-------------------------------------------------------------------------------
1- SQL Profile Finding (see explain plans section below)
--------------------------------------------------------
为此语句找到了性能更好的执行计划 2。选择以下 SQL 概要文件之一进行实施。
SQL profile 未自动创建, 因为经验证可获得的收益太少。
Recommendation (estimated benefit: 26.2%)
-----------------------------------------
- 考虑接受推荐的 SQL 概要文件。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285394, task_owner =>
'SYS', replace => TRUE);
Validation results
------------------
已对 SQL profile 进行测试, 方法为执行其计划和原始计划并测量与计划相对应的执行统计信息。如果其中一个计划运行在很短的时间内就完成,
则另一计划可能只执行了一部分。
Original Plan With SQL Profile % Improved
------------- ---------------- ----------
Completion Status: COMPLETE COMPLETE
Elapsed Time (s): 10.938684 1.332688 87.81 %
CPU Time (s): 10.866348 1.326798 87.78 %
User I/O Time (s): 0 0
Buffer Gets: 947344 699724 26.13 %

Physical Write Bytes: 0 0
Rows Processed: 177 177
Fetches: 177 177
Executions: 1 1
Recommendation (estimated benefit: 99.92%)
------------------------------------------
- 考虑接受建议的 SQL 概要文件, 以便对此语句使用并行执行。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285394, task_owner =>
'SYS', replace => TRUE, profile_type => DBMS_SQLTUNE.PX_PROFILE);
与 DOP 288 并行执行此查询会使 SQL 概要文件计划上的响应时间缩短 99.34%。但是, 启用并行执行时要付出一些代价。它将增加语句的资源消耗
(预计为 89.53%), 这会导致系统吞吐量降低。此外, 由于在非常短的持续时间内消耗了这些资源, 因此如果没有足够可用的硬件容量,
并发语句的响应时间将受到负面影响。
The following data shows some sampled statistics for this SQL from the past
week and projected weekly values when parallel execution is enabled.
Past week sampled statistics for this SQL
-----------------------------------------
Number of executions 0
Percent of total activity 0
Percent of samples with #Active Sessions > 2*CPU 0
Weekly DB time (in sec) 0
Projected statistics with Parallel Execution
--------------------------------------------
Weekly DB time (in sec) 0
2- Index Finding (see explain plans section below)
--------------------------------------------------
通过创建一个或多个索引可以改进此语句的执行计划。
Recommendation (estimated benefit: 99.99%)
------------------------------------------
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_0001003E on JC800.APMACTUALSEQDATAITEM(TO_CHAR("SC
ANTIME",'yyyy-MM-dd HH24:mi:ss'));
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_0001003F on JC800.JITMANPLANPAR("CLIENT","PROPORTI
ONFINGER");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010040 on JC800.BDMWORKCENTERHEADER("PLANT","OBJ
ECTID");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010041 on JC800.JITSHOPKBGATHER("CLIENT","STRATE
BATCHNO","STRATEGY");
Rationale
---------
创建推荐的索引可以显著地改进此语句的执行计划。但是, 使用典型的 SQL 工作量运行 "访问指导"
可能比单个语句更可取。通过这种方法可以获得全面的索引建议案, 包括计算索引维护的开销和附加的空间消耗。

FINDINGS SECTION (2 findings)
-------------------------------------------------------------------------------
1- SQL Profile Finding (see explain plans section below)
--------------------------------------------------------
为此语句找到了性能更好的执行计划 2。选择以下 SQL 概要文件之一进行实施。
SQL profile 未自动创建。
Recommendation (estimated benefit: 98.86%)
------------------------------------------
- 考虑接受推荐的 SQL 概要文件。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285401, task_owner =>
'SYS', replace => TRUE);
Recommendation (estimated benefit: 99.99%)
------------------------------------------
- 考虑接受建议的 SQL 概要文件, 以便对此语句使用并行执行。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285401, task_owner =>
'SYS', replace => TRUE, profile_type => DBMS_SQLTUNE.PX_PROFILE);
与 DOP 288 并行执行此查询会使 SQL 概要文件计划上的响应时间缩短 99.47%。但是, 启用并行执行时要付出一些代价。它将增加语句的资源消耗
(预计为 51.34%), 这会导致系统吞吐量降低。此外, 由于在非常短的持续时间内消耗了这些资源, 因此如果没有足够可用的硬件容量,
并发语句的响应时间将受到负面影响。
The following data shows some sampled statistics for this SQL from the past
week and projected weekly values when parallel execution is enabled.
Past week sampled statistics for this SQL
-----------------------------------------
Number of executions 0
Percent of total activity 0
Percent of samples with #Active Sessions > 2*CPU 0
Weekly DB time (in sec) 0
Projected statistics with Parallel Execution
--------------------------------------------
Weekly DB time (in sec) 0
2- Index Finding (see explain plans section below)
--------------------------------------------------
通过创建一个或多个索引可以改进此语句的执行计划。
Recommendation (estimated benefit: 99.99%)
------------------------------------------
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010044 on JC800.APMACTUALSEQDATAITEM(TO_CHAR("SC
ANTIME",'yyyy-MM-dd HH24:mi:ss'));
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010045 on JC800.BDMWORKCENTERHEADER("PLANT","OBJ
ECTID");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010046 on JC800.JITMANPLANPAR("CLIENT","PROPORTI
ONFINGER");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010047 on JC800.JITSHOPKBGATHER("CLIENT","STRATE
BATCHNO","STRATEGY");
Rationale
---------
创建推荐的索引可以显著地改进此语句的执行计划。但是, 使用典型的 SQL 工作量运行 "访问指导"
可能比单个语句更可取。通过这种方法可以获得全面的索引建议案, 包括计算索引维护的开销和附加的空间消耗。

FINDINGS SECTION (2 findings)
-------------------------------------------------------------------------------
1- SQL Profile Finding (see explain plans section below)
--------------------------------------------------------
为此语句找到了性能更好的执行计划。
Recommendation (estimated benefit: 99.96%)
------------------------------------------
- 考虑接受建议的 SQL 概要文件, 以便对此语句使用并行执行。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285361, task_owner =>
'SYS', replace => TRUE, profile_type => DBMS_SQLTUNE.PX_PROFILE);
与 DOP 288 并行执行此查询会使原始计划上的响应时间缩短 99.96%。但是, 启用并行执行时要付出一些代价。它将增加语句的资源消耗 (预计为
88.89%), 这会导致系统吞吐量降低。此外, 由于在非常短的持续时间内消耗了这些资源, 因此如果没有足够可用的硬件容量,
并发语句的响应时间将受到负面影响。
The following data shows some sampled statistics for this SQL from the past
week and projected weekly values when parallel execution is enabled.
Past week sampled statistics for this SQL
-----------------------------------------
Number of executions 0
Percent of total activity 0
Percent of samples with #Active Sessions > 2*CPU 0
Weekly DB time (in sec) 0
Projected statistics with Parallel Execution
--------------------------------------------
Weekly DB time (in sec) 0
2- Index Finding (see explain plans section below)
--------------------------------------------------
通过创建一个或多个索引可以改进此语句的执行计划。
Recommendation (estimated benefit: 99.85%)
------------------------------------------
- 考虑运行访问指导以改进物理方案设计或者创建推荐的索引。如果选择创建推荐的索引, 请考虑删除索引
"JC800"."BDMWORKCENTERHEADER_WKC", 因为它是推荐的索引的前缀。
create index JC800.IDX$$_0001001C on JC800.BDMWORKCENTERHEADER("WORKCENTER"
,"PLANT");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_0001001D on JC800.APMACTUALSEQDATAITEM(TO_CHAR("SC
ANTIME",'yyyy-MM-dd HH24:mi:ss'));
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_0001001E on JC800.JITMANPLANPAR("CLIENT","PROPORTI
ONFINGER");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_0001001F on JC800.JITSHOPKBGATHER("CLIENT","STRATE
BATCHNO","STRATEGY");
Rationale
---------
创建推荐的索引可以显著地改进此语句的执行计划。但是, 使用典型的 SQL 工作量运行 "访问指导"
可能比单个语句更可取。通过这种方法可以获得全面的索引建议案, 包括计算索引维护的开销和附加的空间消耗。

FINDINGS SECTION (2 findings)
-------------------------------------------------------------------------------
1- SQL Profile Finding (see explain plans section below)
--------------------------------------------------------
为此语句找到了性能更好的执行计划。
SQL profile 未自动创建, 因为经验证可获得的收益太少。
Recommendation (estimated benefit: 41.68%)
------------------------------------------
- 考虑接受推荐的 SQL 概要文件。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285278, task_owner =>
'SYS', replace => TRUE);
Validation results
------------------
已对 SQL profile 进行测试, 方法为执行其计划和原始计划并测量与计划相对应的执行统计信息。如果其中一个计划运行在很短的时间内就完成,
则另一计划可能只执行了一部分。

-----
1. the original plan 的统计信息是 1 执行的平均值。
2. the SQL profile plan 的统计信息是 2 执行的平均值。
2- Index Finding (see explain plans section below)
--------------------------------------------------
通过创建一个或多个索引可以改进此语句的执行计划。
Recommendation (estimated benefit: 99.79%)
------------------------------------------
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010003 on JC800.JITACCSYKBTRUINFO(SYS_OP_C2C("LI
NENO"),SYS_OP_C2C("LOOKNO"));
Rationale
---------
创建推荐的索引可以显著地改进此语句的执行计划。但是, 使用典型的 SQL 工作量运行 "访问指导"
可能比单个语句更可取。通过这种方法可以获得全面的索引建议案, 包括计算索引维护的开销和附加的空间消耗。

FINDINGS SECTION (1 finding)
-------------------------------------------------------------------------------
1- SQL Profile Finding (see explain plans section below)
--------------------------------------------------------
为此语句找到了性能更好的执行计划 2。选择以下 SQL 概要文件之一进行实施。
SQL profile 未自动创建。
Recommendation (estimated benefit: 16%)
---------------------------------------
- 考虑接受推荐的 SQL 概要文件。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285397, task_owner =>
'SYS', replace => TRUE);
Recommendation (estimated benefit: 99.72%)
------------------------------------------
- 考虑接受建议的 SQL 概要文件, 以便对此语句使用并行执行。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285397, task_owner =>
'SYS', replace => TRUE, profile_type => DBMS_SQLTUNE.PX_PROFILE);
与 DOP 288 并行执行此查询会使 SQL 概要文件计划上的响应时间缩短 99.68%。但是, 启用并行执行时要付出一些代价。它将增加语句的资源消耗
(预计为 6.95%), 这会导致系统吞吐量降低。此外, 由于在非常短的持续时间内消耗了这些资源, 因此如果没有足够可用的硬件容量,
并发语句的响应时间将受到负面影响。

FINDINGS SECTION (2 findings)
-------------------------------------------------------------------------------
1- SQL Profile Finding (see explain plans section below)
--------------------------------------------------------
为此语句找到了性能更好的执行计划。
Recommendation (estimated benefit: 99.7%)
-----------------------------------------
- 考虑接受建议的 SQL 概要文件, 以便对此语句使用并行执行。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285325, task_owner =>
'SYS', replace => TRUE, profile_type => DBMS_SQLTUNE.PX_PROFILE);
与 DOP 288 并行执行此查询会使原始计划上的响应时间缩短 99.71%。但是, 启用并行执行时要付出一些代价。它将增加语句的资源消耗 (预计为
15.94%), 这会导致系统吞吐量降低。此外, 由于在非常短的持续时间内消耗了这些资源, 因此如果没有足够可用的硬件容量,
并发语句的响应时间将受到负面影响。
The following data shows some sampled statistics for this SQL from the past
week and projected weekly values when parallel execution is enabled.

2- Alternative Plan Finding
---------------------------
通过搜索系统的实时和历史性能数据找到了此语句的某些替代执行计划。
The following table lists these plans ranked by their average elapsed time.
See section "ALTERNATIVE PLANS SECTION" for detailed information on each
plan.

Information
-----------
- 根据每次执行的用时, 原始计划可能具有最佳性能。但是, 如果您知道某个替代计划优于原始计划, 可以为该替代计划创建 SQL 计划基线。这将指示
Oracle 优化程序在将来优先于任何其他选择来选取它。
execute dbms_sqltune.create_sql_plan_baseline(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285325, owner_name =>
'SYS', plan_hash_value => xxxxxxxx);
-------------------------------------------------------------------------------

FINDINGS SECTION (2 findings)
-------------------------------------------------------------------------------
1- SQL Profile Finding (see explain plans section below)
--------------------------------------------------------
为此语句找到了性能更好的执行计划。
Recommendation (estimated benefit: 99.7%)
-----------------------------------------
- 考虑接受建议的 SQL 概要文件, 以便对此语句使用并行执行。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285373, task_owner =>
'SYS', replace => TRUE, profile_type => DBMS_SQLTUNE.PX_PROFILE);
与 DOP 288 并行执行此查询会使原始计划上的响应时间缩短 99.71%。但是, 启用并行执行时要付出一些代价。它将增加语句的资源消耗 (预计为
15.94%), 这会导致系统吞吐量降低。此外, 由于在非常短的持续时间内消耗了这些资源, 因此如果没有足够可用的硬件容量,
并发语句的响应时间将受到负面影响。
The following data shows some sampled statistics for this SQL from the past
week and projected weekly values when parallel execution is enabled.

Recommendation
--------------
- 请考虑使用最佳平均用时为计划创建 SQL 计划基线。
execute dbms_sqltune.create_sql_plan_baseline(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285373, owner_name =>
'SYS', plan_hash_value => 2556778791);

FINDINGS SECTION (2 findings)
-------------------------------------------------------------------------------
1- Index Finding (see explain plans section below)
--------------------------------------------------
通过创建一个或多个索引可以改进此语句的执行计划。
Recommendation (estimated benefit: 99.69%)
------------------------------------------
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_0001002C on JC800.SCMCOMPLETION("INQURYNO","INQURY
TIMES");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_0001002D on JC800.SCMSUPPLIERRESOURCE("CLIENT","VE
NDORNO","SHORTNAME");
Rationale
---------
创建推荐的索引可以显著地改进此语句的执行计划。但是, 使用典型的 SQL 工作量运行 "访问指导"
可能比单个语句更可取。通过这种方法可以获得全面的索引建议案, 包括计算索引维护的开销和附加的空间消耗。
2- Restructure SQL finding (see plan 1 in explain plans section)
----------------------------------------------------------------
优化程序不能取消执行计划的行 ID 2 处的子查询的嵌套。
Recommendation
--------------
- 考虑用 "NOT EXISTS" 代替 "NOT IN", 或者确保已通过添加 "NOT NULL" 约束条件或 "IS NOT NULL"
谓词将 "NOT IN" 运算符的两边所使用的列声明为 "NOT NULL"。

FINDINGS SECTION (1 finding)
-------------------------------------------------------------------------------
1- Index Finding (see explain plans section below)
--------------------------------------------------
通过创建一个或多个索引可以改进此语句的执行计划。
Recommendation (estimated benefit: 99.03%)
------------------------------------------
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index REPDBNEW.IDX$$_00010004 on
REPDBNEW.FT_GLD_DOCLINE_T("FISCALYEAR","POSTPERIOD");
Rationale
---------
创建推荐的索引可以显著地改进此语句的执行计划。但是, 使用典型的 SQL 工作量运行 "访问指导"
可能比单个语句更可取。通过这种方法可以获得全面的索引建议案, 包括计算索引维护的开销和附加的空间消耗。

FINDINGS SECTION (3 findings)
-------------------------------------------------------------------------------
1- Statistics Finding
---------------------
尚未分析表 "JC800"."MLDTEMP1"。
Recommendation
--------------
- 考虑收集此表的优化程序统计信息。
execute dbms_stats.gather_table_stats(ownname => 'JC800', tabname =>
'MLDTEMP1', estimate_percent => DBMS_STATS.AUTO_SAMPLE_SIZE,
method_opt => 'FOR ALL COLUMNS SIZE AUTO');
Rationale
---------
为了选择好的执行计划, 优化程序需要此表的最新统计信息。
2- SQL Profile Finding (see explain plans section below)
--------------------------------------------------------
为此语句找到了性能更好的执行计划。
SQL 概要文件未自动创建, 因为优化程序统计信息已陈旧或缺失。在创建 SQL 概要文件前, 应先解决基本优化程序统计信息的问题。
Recommendation (estimated benefit: 99%)
---------------------------------------
- 考虑接受推荐的 SQL 概要文件。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285328, task_owner =>
'SYS', replace => TRUE);
Validation results
------------------
已对 SQL profile 进行测试, 方法为执行其计划和原始计划并测量与计划相对应的执行统计信息。如果其中一个计划运行在很短的时间内就完成,
则另一计划可能只执行了一部分。

1. the original plan 的统计信息是 10 执行的平均值。
2. the SQL profile plan 的统计信息是 10 执行的平均值。
3- Alternative Plan Finding
---------------------------
通过搜索系统的实时和历史性能数据找到了此语句的某些替代执行计划。
The following table lists these plans ranked by their average elapsed time.
See section "ALTERNATIVE PLANS SECTION" for detailed information on each
plan.

Information
-----------
- 因为找不到原始计划的任何执行历史记录, SQL 优化指导无法确定这些执行计划中是否有一些执行计划优于原始计划。但是,
如果您知道某个替代计划优于原始计划, 可以为该替代计划创建 SQL 计划基线。这将指示 Oracle 优化程序在将来优先于任何其他选择来选取它。
execute dbms_sqltune.create_sql_plan_baseline(task_name =>

---------
创建推荐的索引可以显著地改进此语句的执行计划。但是, 使用典型的 SQL 工作量运行 "访问指导"
可能比单个语句更可取。通过这种方法可以获得全面的索引建议案, 包括计算索引维护的开销和附加的空间消耗。

FINDINGS SECTION (4 findings)
-------------------------------------------------------------------------------
1- SQL Profile Finding (see explain plans section below)
--------------------------------------------------------
为此语句找到了性能更好的执行计划。
SQL profile 未自动创建, 因为经验证可获得的收益太少。
Recommendation (estimated benefit: 28.81%)
------------------------------------------
- 考虑接受推荐的 SQL 概要文件。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285266, task_owner =>
'SYS', replace => TRUE);
Validation results
------------------
已对 SQL profile 进行测试, 方法为执行其计划和原始计划并测量与计划相对应的执行统计信息。如果其中一个计划运行在很短的时间内就完成,
则另一计划可能只执行了一部分。
Original Plan With SQL Profile % Improved
------------- ---------------- ----------
Completion Status: COMPLETE COMPLETE
Elapsed Time (s): 1.500657 1.156117 22.95 %
CPU Time (s): 1.497771 1.146825 23.43 %
User I/O Time (s): 0 0
Buffer Gets: 362807 258250 28.81 %
Physical Read Requests: 0 0
Physical Write Requests: 0 0
Physical Read Bytes: 0 0
Physical Write Bytes: 0 0
Rows Processed: 28391 28391
Fetches: 28391 28391
Executions: 1 1
2- Index Finding (see explain plans section below)
--------------------------------------------------
通过创建一个或多个索引可以改进此语句的执行计划。
Recommendation (estimated benefit: 76.11%)
------------------------------------------
- 考虑运行访问指导以改进物理方案设计或者创建推荐的索引。如果选择创建推荐的索引, 请考虑删除索引
"JC800"."BDMWORKCENTERHEADER_WKC", 因为它是推荐的索引的前缀。
create index JC800.IDX$$_00010001 on JC800.BDMWORKCENTERHEADER("WORKCENTER"
,"PLANT");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010002 on JC800.APMACTUALSEQDATAITEM(TO_CHAR("SC
ANDATE",'yyyy-MM-dd'));
Rationale
---------
创建推荐的索引可以显著地改进此语句的执行计划。但是, 使用典型的 SQL 工作量运行 "访问指导"
可能比单个语句更可取。通过这种方法可以获得全面的索引建议案, 包括计算索引维护的开销和附加的空间消耗。
3- Restructure SQL finding (see plan 1 in explain plans section)
----------------------------------------------------------------
谓词 TO_CHAR("APMACTUALS1_"."SCANDATE",'yyyy-MM-dd')>='2017-01-05' (在执行计划的行 ID
13 处使用) 包含索引列 "SCANDATE" 的表达式。此表达式使优化程序无法选择表 "JC800"."APMACTUALSEQDATAITEM"
的索引。
Recommendation
--------------
- 将谓词重写为等价型以便使用索引。或者, 对此表达式创建基于函数的索引。
4- Alternative Plan Finding
---------------------------
通过搜索系统的实时和历史性能数据找到了此语句的某些替代执行计划。
The following table lists these plans ranked by their average elapsed time.
See section "ALTERNATIVE PLANS SECTION" for detailed information on each
plan.
id plan hash last seen elapsed (s) origin note
-- ---------- -------------------- ------------ --------------- --------------
1 4104233932 2017-02-15/00:00:14 1.617 Cursor Cache original plan
2 3793614319 2017-02-15/00:02:14 1.680 Cursor Cache
Information
-----------
- 根据每次执行的用时, 原始计划可能具有最佳性能。但是, 如果您知道某个替代计划优于原始计划, 可以为该替代计划创建 SQL 计划基线。这将指示
Oracle 优化程序在将来优先于任何其他选择来选取它。

FINDINGS SECTION (2 findings)
-------------------------------------------------------------------------------
1- Index Finding (see explain plans section below)
--------------------------------------------------
通过创建一个或多个索引可以改进此语句的执行计划。
Recommendation (estimated benefit: 68.67%)
------------------------------------------
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010042 on JC800.APMACTUALSEQDATAITEM("CLIENT","S
CANTIME");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010043 on JC800.BDMWORKCENTERHEADER("OBJECTID");
Rationale
---------
创建推荐的索引可以显著地改进此语句的执行计划。但是, 使用典型的 SQL 工作量运行 "访问指导"
可能比单个语句更可取。通过这种方法可以获得全面的索引建议案, 包括计算索引维护的开销和附加的空间消耗。
2- Alternative Plan Finding
---------------------------
通过搜索系统的实时和历史性能数据找到了此语句的某些替代执行计划。
The following table lists these plans ranked by their average elapsed time.

-----------
- 根据每次执行的用时, 原始计划可能具有最佳性能。但是, 如果您知道某个替代计划优于原始计划, 可以为该替代计划创建 SQL 计划基线。这将指示
Oracle 优化程序在将来优先于任何其他选择来选取它。

FINDINGS SECTION (2 findings)
-------------------------------------------------------------------------------
1- SQL Profile Finding (see explain plans section below)
--------------------------------------------------------
为此语句找到了性能更好的执行计划 2。选择以下 SQL 概要文件之一进行实施。
由于 SQL profile 可能造成了显著的 I/O 时间缩短, 因此未自动创建它。
Recommendation (estimated benefit: 67.21%)
------------------------------------------
- 考虑接受推荐的 SQL 概要文件。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285327, task_owner =>
'SYS', replace => TRUE);
Validation results
------------------
已对 SQL profile 进行测试, 方法为执行其计划和原始计划并测量与计划相对应的执行统计信息。如果其中一个计划运行在很短的时间内就完成,
则另一计划可能只执行了一部分。
Original Plan With SQL Profile % Improved

Recommendation (estimated benefit: 99.97%)
------------------------------------------
- 考虑接受建议的 SQL 概要文件, 以便对此语句使用并行执行。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285327, task_owner =>
'SYS', replace => TRUE, profile_type => DBMS_SQLTUNE.PX_PROFILE);
与 DOP 288 并行执行此查询会使 SQL 概要文件计划上的响应时间缩短 99.34%。但是, 启用并行执行时要付出一些代价。它将增加语句的资源消耗
(预计为 89.93%), 这会导致系统吞吐量降低。此外, 由于在非常短的持续时间内消耗了这些资源, 因此如果没有足够可用的硬件容量,
并发语句的响应时间将受到负面影响。

2- Index Finding (see explain plans section below)
--------------------------------------------------
通过创建一个或多个索引可以改进此语句的执行计划。
Recommendation (estimated benefit: 99.99%)
------------------------------------------
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_0001000D on JC800.APMACTUALSEQDATAITEM(TO_CHAR("SC
ANTIME",'yyyy-MM-dd HH24:mi:ss'));
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_0001000E on JC800.BDMWORKCENTERHEADER("PLANT","OBJ
ECTID");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_0001000F on JC800.JITMANPLANPAR("CLIENT","PROPORTI
ONFINGER");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010010 on JC800.JITSHOPKBGATHER("CLIENT","STRATE
BATCHNO","STRATEGY");
Rationale
---------
创建推荐的索引可以显著地改进此语句的执行计划。但是, 使用典型的 SQL 工作量运行 "访问指导"
可能比单个语句更可取。通过这种方法可以获得全面的索引建议案, 包括计算索引维护的开销和附加的空间消耗。

FINDINGS SECTION (2 findings)
-------------------------------------------------------------------------------
1- SQL Profile Finding (see explain plans section below)
--------------------------------------------------------
为此语句找到了性能更好的执行计划 2。选择以下 SQL 概要文件之一进行实施。
SQL profile 未自动创建, 因为自动创建功能已禁用。请将任务参数 ACCEPT_SQL_PROFILES 设置为 TRUE 以启用自动创建功能。
Recommendation (estimated benefit: 76.13%)
------------------------------------------
- 考虑接受推荐的 SQL 概要文件。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285360, task_owner =>
'SYS', replace => TRUE);
Validation results
------------------
已对 SQL profile 进行测试, 方法为执行其计划和原始计划并测量与计划相对应的执行统计信息。如果其中一个计划运行在很短的时间内就完成,
则另一计划可能只执行了一部分。
Original Plan With SQL Profile % Improved
------------- ---------------- ----------
Completion Status: PARTIAL COMPLETE
Elapsed Time (s): 30.62509 1.220906 96.01 %
CPU Time (s): 30.497364 1.200818 96.06 %

Physical Write Bytes: 0 0
Rows Processed: 0 607
Fetches: 0 607
Executions: 0 1
Recommendation (estimated benefit: 99.98%)
------------------------------------------
- 考虑接受建议的 SQL 概要文件, 以便对此语句使用并行执行。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285360, task_owner =>
'SYS', replace => TRUE, profile_type => DBMS_SQLTUNE.PX_PROFILE);
与 DOP 288 并行执行此查询会使 SQL 概要文件计划上的响应时间缩短 99.34%。但是, 启用并行执行时要付出一些代价。它将增加语句的资源消耗
(预计为 89.59%), 这会导致系统吞吐量降低。此外, 由于在非常短的持续时间内消耗了这些资源, 因此如果没有足够可用的硬件容量,
并发语句的响应时间将受到负面影响。
The following data shows some sampled statistics for this SQL from the past
week and projected weekly values when parallel execution is enabled.
Past week sampled statistics for this SQL
-----------------------------------------
Number of executions 0
Percent of total activity 0
Percent of samples with #Active Sessions > 2*CPU 0
Weekly DB time (in sec) 0
Projected statistics with Parallel Execution
--------------------------------------------
Weekly DB time (in sec) 0
2- Index Finding (see explain plans section below)
--------------------------------------------------
通过创建一个或多个索引可以改进此语句的执行计划。
Recommendation (estimated benefit: 99.99%)
------------------------------------------
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010018 on JC800.APMACTUALSEQDATAITEM(TO_CHAR("SC
ANTIME",'yyyy-MM-dd HH24:mi:ss'));
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010019 on JC800.JITMANPLANPAR("CLIENT","PROPORTI
ONFINGER");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_0001001A on JC800.BDMWORKCENTERHEADER("PLANT","OBJ
ECTID");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_0001001B on JC800.JITSHOPKBGATHER("CLIENT","STRATE
BATCHNO","STRATEGY");
Rationale
---------
创建推荐的索引可以显著地改进此语句的执行计划。但是, 使用典型的 SQL 工作量运行 "访问指导"
可能比单个语句更可取。通过这种方法可以获得全面的索引建议案, 包括计算索引维护的开销和附加的空间消耗。

FINDINGS SECTION (2 findings)
-------------------------------------------------------------------------------
1- SQL Profile Finding (see explain plans section below)
--------------------------------------------------------
为此语句找到了性能更好的执行计划 2。选择以下 SQL 概要文件之一进行实施。
SQL profile 未自动创建, 因为自动创建功能已禁用。请将任务参数 ACCEPT_SQL_PROFILES 设置为 TRUE 以启用自动创建功能。
Recommendation (estimated benefit: 69.14%)
------------------------------------------
- 考虑接受推荐的 SQL 概要文件。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285363, task_owner =>
'SYS', replace => TRUE);
Validation results
------------------
已对 SQL profile 进行测试, 方法为执行其计划和原始计划并测量与计划相对应的执行统计信息。如果其中一个计划运行在很短的时间内就完成,
则另一计划可能只执行了一部分。
Original Plan With SQL Profile % Improved
------------- ---------------- ----------
Completion Status: COMPLETE COMPLETE
Elapsed Time (s): 23.412212 1.388229 94.07 %
CPU Time (s): 23.384445 1.373792 94.12 %

Rows Processed: 426 426
Fetches: 426 426
Executions: 1 1
Recommendation (estimated benefit: 99.96%)
------------------------------------------
- 考虑接受建议的 SQL 概要文件, 以便对此语句使用并行执行。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285363, task_owner =>
'SYS', replace => TRUE, profile_type => DBMS_SQLTUNE.PX_PROFILE);
与 DOP 288 并行执行此查询会使 SQL 概要文件计划上的响应时间缩短 99.34%。但是, 启用并行执行时要付出一些代价。它将增加语句的资源消耗
(预计为 89.63%), 这会导致系统吞吐量降低。此外, 由于在非常短的持续时间内消耗了这些资源, 因此如果没有足够可用的硬件容量,
并发语句的响应时间将受到负面影响。
The following data shows some sampled statistics for this SQL from the past
week and projected weekly values when parallel execution is enabled.
Past week sampled statistics for this SQL
-----------------------------------------
Number of executions 0
Percent of total activity 0
Percent of samples with #Active Sessions > 2*CPU 0
Weekly DB time (in sec) 0
Projected statistics with Parallel Execution
--------------------------------------------
Weekly DB time (in sec) 0
2- Index Finding (see explain plans section below)
--------------------------------------------------
通过创建一个或多个索引可以改进此语句的执行计划。
Recommendation (estimated benefit: 99.99%)
------------------------------------------
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010020 on JC800.APMACTUALSEQDATAITEM(TO_CHAR("SC
ANTIME",'yyyy-MM-dd HH24:mi:ss'));
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010021 on JC800.BDMWORKCENTERHEADER("PLANT","OBJ
ECTID");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010022 on JC800.JITMANPLANPAR("CLIENT","PROPORTI
ONFINGER");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010023 on JC800.JITSHOPKBGATHER("CLIENT","STRATE
BATCHNO","STRATEGY");
Rationale
---------
创建推荐的索引可以显著地改进此语句的执行计划。但是, 使用典型的 SQL 工作量运行 "访问指导"
可能比单个语句更可取。通过这种方法可以获得全面的索引建议案, 包括计算索引维护的开销和附加的空间消耗。

FINDINGS SECTION (2 findings)
-------------------------------------------------------------------------------
1- SQL Profile Finding (see explain plans section below)
--------------------------------------------------------
为此语句找到了性能更好的执行计划 2。选择以下 SQL 概要文件之一进行实施。
SQL profile 未自动创建, 因为自动创建功能已禁用。请将任务参数 ACCEPT_SQL_PROFILES 设置为 TRUE 以启用自动创建功能。
Recommendation (estimated benefit: 70.52%)
------------------------------------------
- 考虑接受推荐的 SQL 概要文件。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285377, task_owner =>
'SYS', replace => TRUE);
Validation results
------------------
已对 SQL profile 进行测试, 方法为执行其计划和原始计划并测量与计划相对应的执行统计信息。如果其中一个计划运行在很短的时间内就完成,
则另一计划可能只执行了一部分。
Original Plan With SQL Profile % Improved
------------- ---------------- ----------
Completion Status: COMPLETE COMPLETE
Elapsed Time (s): 24.122076 1.335963 94.46 %
CPU Time (s): 24.07034 1.307802 94.56 %
User I/O Time (s): 0 .01639

Physical Write Bytes: 0 0
Rows Processed: 453 453
Fetches: 453 453
Executions: 1 1
Recommendation (estimated benefit: 99.99%)
------------------------------------------
- 考虑接受建议的 SQL 概要文件, 以便对此语句使用并行执行。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285377, task_owner =>
'SYS', replace => TRUE, profile_type => DBMS_SQLTUNE.PX_PROFILE);
与 DOP 288 并行执行此查询会使 SQL 概要文件计划上的响应时间缩短 99.47%。但是, 启用并行执行时要付出一些代价。它将增加语句的资源消耗
(预计为 51.33%), 这会导致系统吞吐量降低。此外, 由于在非常短的持续时间内消耗了这些资源, 因此如果没有足够可用的硬件容量,
并发语句的响应时间将受到负面影响。
The following data shows some sampled statistics for this SQL from the past
week and projected weekly values when parallel execution is enabled.
Past week sampled statistics for this SQL
-----------------------------------------
Number of executions 0
Percent of total activity 0
Percent of samples with #Active Sessions > 2*CPU 0
Weekly DB time (in sec) 0
Projected statistics with Parallel Execution
--------------------------------------------
Weekly DB time (in sec) 0
2- Index Finding (see explain plans section below)
--------------------------------------------------
通过创建一个或多个索引可以改进此语句的执行计划。
Recommendation (estimated benefit: 99.99%)
------------------------------------------
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010028 on JC800.APMACTUALSEQDATAITEM(TO_CHAR("SC
ANTIME",'yyyy-MM-dd HH24:mi:ss'));
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010029 on JC800.BDMWORKCENTERHEADER("PLANT","OBJ
ECTID");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_0001002A on JC800.JITMANPLANPAR("CLIENT","PROPORTI
ONFINGER");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_0001002B on JC800.JITSHOPKBGATHER("CLIENT","STRATE
BATCHNO","STRATEGY");
Rationale
---------
创建推荐的索引可以显著地改进此语句的执行计划。但是, 使用典型的 SQL 工作量运行 "访问指导"
可能比单个语句更可取。通过这种方法可以获得全面的索引建议案, 包括计算索引维护的开销和附加的空间消耗。

FINDINGS SECTION (2 findings)
-------------------------------------------------------------------------------
1- SQL Profile Finding (see explain plans section below)
--------------------------------------------------------
为此语句找到了性能更好的执行计划 2。选择以下 SQL 概要文件之一进行实施。
SQL profile 未自动创建, 因为经验证可获得的收益太少。
Recommendation (estimated benefit: 49.59%)
------------------------------------------
- 考虑接受推荐的 SQL 概要文件。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285380, task_owner =>
'SYS', replace => TRUE);
Validation results
------------------
已对 SQL profile 进行测试, 方法为执行其计划和原始计划并测量与计划相对应的执行统计信息。如果其中一个计划运行在很短的时间内就完成,
则另一计划可能只执行了一部分。
Original Plan With SQL Profile % Improved
------------- ---------------- ----------
Completion Status: COMPLETE COMPLETE
Elapsed Time (s): 13.490854 1.078417 92 %
CPU Time (s): 13.476952 1.077836 92 %
User I/O Time (s): 0 0
Buffer Gets: 1387604 699943 49.55 %
Physical Read Requests: 0 0
Physical Write Requests: 0 0
Physical Read Bytes: 0 0
Physical Write Bytes: 0 0
Rows Processed: 264 264
Fetches: 264 264
Executions: 1 1
Recommendation (estimated benefit: 99.96%)
------------------------------------------
- 考虑接受建议的 SQL 概要文件, 以便对此语句使用并行执行。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285380, task_owner =>
'SYS', replace => TRUE, profile_type => DBMS_SQLTUNE.PX_PROFILE);
与 DOP 288 并行执行此查询会使 SQL 概要文件计划上的响应时间缩短 99.47%。但是, 启用并行执行时要付出一些代价。它将增加语句的资源消耗
(预计为 51.64%), 这会导致系统吞吐量降低。此外, 由于在非常短的持续时间内消耗了这些资源, 因此如果没有足够可用的硬件容量,
并发语句的响应时间将受到负面影响。
The following data shows some sampled statistics for this SQL from the past
week and projected weekly values when parallel execution is enabled.
Past week sampled statistics for this SQL
-----------------------------------------
Number of executions 0
Percent of total activity 0
Percent of samples with #Active Sessions > 2*CPU 0
Weekly DB time (in sec) 0
Projected statistics with Parallel Execution
--------------------------------------------
Weekly DB time (in sec) 0
2- Index Finding (see explain plans section below)
--------------------------------------------------
通过创建一个或多个索引可以改进此语句的执行计划。
Recommendation (estimated benefit: 99.99%)
------------------------------------------
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_0001002E on JC800.APMACTUALSEQDATAITEM(TO_CHAR("SC
ANTIME",'yyyy-MM-dd HH24:mi:ss'));
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_0001002F on JC800.BDMWORKCENTERHEADER("PLANT","OBJ
ECTID");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010030 on JC800.JITMANPLANPAR("CLIENT","PROPORTI
ONFINGER");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010031 on JC800.JITSHOPKBGATHER("CLIENT","STRATE
BATCHNO","STRATEGY");
Rationale
---------
创建推荐的索引可以显著地改进此语句的执行计划。但是, 使用典型的 SQL 工作量运行 "访问指导"
可能比单个语句更可取。通过这种方法可以获得全面的索引建议案, 包括计算索引维护的开销和附加的空间消耗。

FINDINGS SECTION (2 findings)
-------------------------------------------------------------------------------
1- SQL Profile Finding (see explain plans section below)
--------------------------------------------------------
为此语句找到了性能更好的执行计划 2。选择以下 SQL 概要文件之一进行实施。
SQL profile 未自动创建, 因为自动创建功能已禁用。请将任务参数 ACCEPT_SQL_PROFILES 设置为 TRUE 以启用自动创建功能。
Recommendation (estimated benefit: 66.72%)
------------------------------------------
- 考虑接受推荐的 SQL 概要文件。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285381, task_owner =>
'SYS', replace => TRUE);
Validation results
------------------
已对 SQL profile 进行测试, 方法为执行其计划和原始计划并测量与计划相对应的执行统计信息。如果其中一个计划运行在很短的时间内就完成,
则另一计划可能只执行了一部分。
Original Plan With SQL Profile % Improved
------------- ---------------- ----------
Completion Status: COMPLETE COMPLETE
Elapsed Time (s): 21.793969 1.391961 93.61 %
CPU Time (s): 21.757693 1.390789 93.6 %

Rows Processed: 401 401
Fetches: 401 401
Executions: 1 1
Recommendation (estimated benefit: 99.98%)
------------------------------------------
- 考虑接受建议的 SQL 概要文件, 以便对此语句使用并行执行。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285381, task_owner =>
'SYS', replace => TRUE, profile_type => DBMS_SQLTUNE.PX_PROFILE);
与 DOP 288 并行执行此查询会使 SQL 概要文件计划上的响应时间缩短 99.47%。但是, 启用并行执行时要付出一些代价。它将增加语句的资源消耗
(预计为 51.76%), 这会导致系统吞吐量降低。此外, 由于在非常短的持续时间内消耗了这些资源, 因此如果没有足够可用的硬件容量,
并发语句的响应时间将受到负面影响。
The following data shows some sampled statistics for this SQL from the past
week and projected weekly values when parallel execution is enabled.
Past week sampled statistics for this SQL
-----------------------------------------
Number of executions 0
Percent of total activity 0
Percent of samples with #Active Sessions > 2*CPU 0
Weekly DB time (in sec) 0
Projected statistics with Parallel Execution
--------------------------------------------
Weekly DB time (in sec) 0
2- Index Finding (see explain plans section below)
--------------------------------------------------
通过创建一个或多个索引可以改进此语句的执行计划。
Recommendation (estimated benefit: 99.99%)
------------------------------------------
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010032 on JC800.APMACTUALSEQDATAITEM(TO_CHAR("SC
ANTIME",'yyyy-MM-dd HH24:mi:ss'));
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010033 on JC800.BDMWORKCENTERHEADER("PLANT","OBJ
ECTID");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010034 on JC800.JITMANPLANPAR("CLIENT","PROPORTI
ONFINGER");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010035 on JC800.JITSHOPKBGATHER("CLIENT","STRATE
BATCHNO","STRATEGY");
Rationale
---------
创建推荐的索引可以显著地改进此语句的执行计划。但是, 使用典型的 SQL 工作量运行 "访问指导"
可能比单个语句更可取。通过这种方法可以获得全面的索引建议案, 包括计算索引维护的开销和附加的空间消耗。

FINDINGS SECTION (2 findings)
-------------------------------------------------------------------------------
1- SQL Profile Finding (see explain plans section below)
--------------------------------------------------------
为此语句找到了性能更好的执行计划 2。选择以下 SQL 概要文件之一进行实施。
SQL profile 未自动创建, 因为经验证可获得的收益太少。
Recommendation (estimated benefit: 49.02%)
------------------------------------------
- 考虑接受推荐的 SQL 概要文件。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285384, task_owner =>
'SYS', replace => TRUE);
Validation results
------------------
已对 SQL profile 进行测试, 方法为执行其计划和原始计划并测量与计划相对应的执行统计信息。如果其中一个计划运行在很短的时间内就完成,
则另一计划可能只执行了一部分。
Original Plan With SQL Profile % Improved
------------- ---------------- ----------
Completion Status: COMPLETE COMPLETE
Elapsed Time (s): 15.089957 1.456678 90.34 %
CPU Time (s): 15.034715 1.44778 90.37 %

Physical Write Bytes: 0 0
Rows Processed: 261 261
Fetches: 261 261
Executions: 1 1
Recommendation (estimated benefit: 99.98%)
------------------------------------------
- 考虑接受建议的 SQL 概要文件, 以便对此语句使用并行执行。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285384, task_owner =>
'SYS', replace => TRUE, profile_type => DBMS_SQLTUNE.PX_PROFILE);
与 DOP 288 并行执行此查询会使 SQL 概要文件计划上的响应时间缩短 99.48%。但是, 启用并行执行时要付出一些代价。它将增加语句的资源消耗
(预计为 50.86%), 这会导致系统吞吐量降低。此外, 由于在非常短的持续时间内消耗了这些资源, 因此如果没有足够可用的硬件容量,
并发语句的响应时间将受到负面影响。
The following data shows some sampled statistics for this SQL from the past
week and projected weekly values when parallel execution is enabled.
Past week sampled statistics for this SQL
-----------------------------------------
Number of executions 0
Percent of total activity 0
Percent of samples with #Active Sessions > 2*CPU 0
Weekly DB time (in sec) 0
Projected statistics with Parallel Execution
--------------------------------------------
Weekly DB time (in sec) 0
2- Index Finding (see explain plans section below)
--------------------------------------------------
通过创建一个或多个索引可以改进此语句的执行计划。
Recommendation (estimated benefit: 99.99%)
------------------------------------------
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010036 on JC800.APMACTUALSEQDATAITEM(TO_CHAR("SC
ANTIME",'yyyy-MM-dd HH24:mi:ss'));
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010037 on JC800.JITMANPLANPAR("CLIENT","PROPORTI
ONFINGER");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010038 on JC800.BDMWORKCENTERHEADER("PLANT","OBJ
ECTID");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010039 on JC800.JITSHOPKBGATHER("CLIENT","STRATE
BATCHNO","STRATEGY");
Rationale
---------
创建推荐的索引可以显著地改进此语句的执行计划。但是, 使用典型的 SQL 工作量运行 "访问指导"
可能比单个语句更可取。通过这种方法可以获得全面的索引建议案, 包括计算索引维护的开销和附加的空间消耗。

FINDINGS SECTION (2 findings)
-------------------------------------------------------------------------------
1- SQL Profile Finding (see explain plans section below)
--------------------------------------------------------
为此语句找到了性能更好的执行计划 2。选择以下 SQL 概要文件之一进行实施。
SQL profile 未自动创建, 因为自动创建功能已禁用。请将任务参数 ACCEPT_SQL_PROFILES 设置为 TRUE 以启用自动创建功能。
Recommendation (estimated benefit: 71.16%)
------------------------------------------
- 考虑接受推荐的 SQL 概要文件。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285386, task_owner =>
'SYS', replace => TRUE);
Validation results
------------------
已对 SQL profile 进行测试, 方法为执行其计划和原始计划并测量与计划相对应的执行统计信息。如果其中一个计划运行在很短的时间内就完成,
则另一计划可能只执行了一部分。
Original Plan With SQL Profile % Improved
------------- ---------------- ----------
Completion Status: COMPLETE COMPLETE
Elapsed Time (s): 25.30354 1.317776 94.79 %
CPU Time (s): 25.226165 1.305803 94.82 %

Rows Processed: 456 456
Fetches: 456 456
Executions: 1 1
Recommendation (estimated benefit: 99.99%)
------------------------------------------
- 考虑接受建议的 SQL 概要文件, 以便对此语句使用并行执行。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285386, task_owner =>
'SYS', replace => TRUE, profile_type => DBMS_SQLTUNE.PX_PROFILE);
与 DOP 288 并行执行此查询会使 SQL 概要文件计划上的响应时间缩短 99.34%。但是, 启用并行执行时要付出一些代价。它将增加语句的资源消耗
(预计为 89.94%), 这会导致系统吞吐量降低。此外, 由于在非常短的持续时间内消耗了这些资源, 因此如果没有足够可用的硬件容量,
并发语句的响应时间将受到负面影响。
The following data shows some sampled statistics for this SQL from the past
week and projected weekly values when parallel execution is enabled.

Weekly DB time (in sec) 0
2- Index Finding (see explain plans section below)
--------------------------------------------------
通过创建一个或多个索引可以改进此语句的执行计划。
Recommendation (estimated benefit: 99.99%)
------------------------------------------
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_0001003A on JC800.APMACTUALSEQDATAITEM(TO_CHAR("SC
ANTIME",'yyyy-MM-dd HH24:mi:ss'));
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_0001003B on JC800.BDMWORKCENTERHEADER("PLANT","OBJ
ECTID");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_0001003C on JC800.JITMANPLANPAR("CLIENT","PROPORTI
ONFINGER");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_0001003D on JC800.JITSHOPKBGATHER("CLIENT","STRATE
BATCHNO","STRATEGY");
Rationale
---------
创建推荐的索引可以显著地改进此语句的执行计划。但是, 使用典型的 SQL 工作量运行 "访问指导"
可能比单个语句更可取。通过这种方法可以获得全面的索引建议案, 包括计算索引维护的开销和附加的空间消耗。

已对 SQL profile 进行测试, 方法为执行其计划和原始计划并测量与计划相对应的执行统计信息。如果其中一个计划运行在很短的时间内就完成,
则另一计划可能只执行了一部分。

Recommendation (estimated benefit: 99.92%)
------------------------------------------
- 考虑接受建议的 SQL 概要文件, 以便对此语句使用并行执行。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285394, task_owner =>
'SYS', replace => TRUE, profile_type => DBMS_SQLTUNE.PX_PROFILE);
与 DOP 288 并行执行此查询会使 SQL 概要文件计划上的响应时间缩短 99.34%。但是, 启用并行执行时要付出一些代价。它将增加语句的资源消耗
(预计为 89.53%), 这会导致系统吞吐量降低。此外, 由于在非常短的持续时间内消耗了这些资源, 因此如果没有足够可用的硬件容量,
并发语句的响应时间将受到负面影响。

2- Index Finding (see explain plans section below)
--------------------------------------------------
通过创建一个或多个索引可以改进此语句的执行计划。
Recommendation (estimated benefit: 99.99%)
------------------------------------------
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_0001003E on JC800.APMACTUALSEQDATAITEM(TO_CHAR("SC
ANTIME",'yyyy-MM-dd HH24:mi:ss'));
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_0001003F on JC800.JITMANPLANPAR("CLIENT","PROPORTI
ONFINGER");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010040 on JC800.BDMWORKCENTERHEADER("PLANT","OBJ
ECTID");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010041 on JC800.JITSHOPKBGATHER("CLIENT","STRATE
BATCHNO","STRATEGY");
Rationale
---------
创建推荐的索引可以显著地改进此语句的执行计划。但是, 使用典型的 SQL 工作量运行 "访问指导"
可能比单个语句更可取。通过这种方法可以获得全面的索引建议案, 包括计算索引维护的开销和附加的空间消耗。

FINDINGS SECTION (2 findings)
-------------------------------------------------------------------------------
1- SQL Profile Finding (see explain plans section below)
--------------------------------------------------------
为此语句找到了性能更好的执行计划 2。选择以下 SQL 概要文件之一进行实施。
SQL profile 未自动创建。
Recommendation (estimated benefit: 98.86%)
------------------------------------------
- 考虑接受推荐的 SQL 概要文件。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285401, task_owner =>
'SYS', replace => TRUE);
Recommendation (estimated benefit: 99.99%)
------------------------------------------
- 考虑接受建议的 SQL 概要文件, 以便对此语句使用并行执行。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285401, task_owner =>
'SYS', replace => TRUE, profile_type => DBMS_SQLTUNE.PX_PROFILE);
与 DOP 288 并行执行此查询会使 SQL 概要文件计划上的响应时间缩短 99.47%。但是, 启用并行执行时要付出一些代价。它将增加语句的资源消耗
(预计为 51.34%), 这会导致系统吞吐量降低。此外, 由于在非常短的持续时间内消耗了这些资源, 因此如果没有足够可用的硬件容量,
并发语句的响应时间将受到负面影响。
The following data shows some sampled statistics for this SQL from the past
week and projected weekly values when parallel execution is enabled.
Past week sampled statistics for this SQL
-----------------------------------------
Number of executions 0
Percent of total activity 0
Percent of samples with #Active Sessions > 2*CPU 0
Weekly DB time (in sec) 0
Projected statistics with Parallel Execution
--------------------------------------------
Weekly DB time (in sec) 0
2- Index Finding (see explain plans section below)
--------------------------------------------------
通过创建一个或多个索引可以改进此语句的执行计划。
Recommendation (estimated benefit: 99.99%)
------------------------------------------
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010044 on JC800.APMACTUALSEQDATAITEM(TO_CHAR("SC
ANTIME",'yyyy-MM-dd HH24:mi:ss'));
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010045 on JC800.BDMWORKCENTERHEADER("PLANT","OBJ
ECTID");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010046 on JC800.JITMANPLANPAR("CLIENT","PROPORTI
ONFINGER");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010047 on JC800.JITSHOPKBGATHER("CLIENT","STRATE
BATCHNO","STRATEGY");
Rationale
---------
创建推荐的索引可以显著地改进此语句的执行计划。但是, 使用典型的 SQL 工作量运行 "访问指导"
可能比单个语句更可取。通过这种方法可以获得全面的索引建议案, 包括计算索引维护的开销和附加的空间消耗。

FINDINGS SECTION (2 findings)
-------------------------------------------------------------------------------
1- SQL Profile Finding (see explain plans section below)
--------------------------------------------------------
为此语句找到了性能更好的执行计划。
Recommendation (estimated benefit: 99.96%)
------------------------------------------
- 考虑接受建议的 SQL 概要文件, 以便对此语句使用并行执行。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285361, task_owner =>
'SYS', replace => TRUE, profile_type => DBMS_SQLTUNE.PX_PROFILE);
与 DOP 288 并行执行此查询会使原始计划上的响应时间缩短 99.96%。但是, 启用并行执行时要付出一些代价。它将增加语句的资源消耗 (预计为
88.89%), 这会导致系统吞吐量降低。此外, 由于在非常短的持续时间内消耗了这些资源, 因此如果没有足够可用的硬件容量,
并发语句的响应时间将受到负面影响。
The following data shows some sampled statistics for this SQL from the past
week and projected weekly values when parallel execution is enabled.
Past week sampled statistics for this SQL
-----------------------------------------
Number of executions 0
Percent of total activity 0
Percent of samples with #Active Sessions > 2*CPU 0
Weekly DB time (in sec) 0
Projected statistics with Parallel Execution
--------------------------------------------
Weekly DB time (in sec) 0
2- Index Finding (see explain plans section below)
--------------------------------------------------
通过创建一个或多个索引可以改进此语句的执行计划。
Recommendation (estimated benefit: 99.85%)
------------------------------------------
- 考虑运行访问指导以改进物理方案设计或者创建推荐的索引。如果选择创建推荐的索引, 请考虑删除索引
"JC800"."BDMWORKCENTERHEADER_WKC", 因为它是推荐的索引的前缀。
create index JC800.IDX$$_0001001C on JC800.BDMWORKCENTERHEADER("WORKCENTER"
,"PLANT");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_0001001D on JC800.APMACTUALSEQDATAITEM(TO_CHAR("SC
ANTIME",'yyyy-MM-dd HH24:mi:ss'));
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_0001001E on JC800.JITMANPLANPAR("CLIENT","PROPORTI
ONFINGER");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_0001001F on JC800.JITSHOPKBGATHER("CLIENT","STRATE
BATCHNO","STRATEGY");
Rationale
---------
创建推荐的索引可以显著地改进此语句的执行计划。但是, 使用典型的 SQL 工作量运行 "访问指导"
可能比单个语句更可取。通过这种方法可以获得全面的索引建议案, 包括计算索引维护的开销和附加的空间消耗。

1- SQL Profile Finding (see explain plans section below)
--------------------------------------------------------
为此语句找到了性能更好的执行计划。
SQL profile 未自动创建, 因为经验证可获得的收益太少。
Recommendation (estimated benefit: 41.68%)
------------------------------------------
- 考虑接受推荐的 SQL 概要文件。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285278, task_owner =>
'SYS', replace => TRUE);
Validation results
------------------
已对 SQL profile 进行测试, 方法为执行其计划和原始计划并测量与计划相对应的执行统计信息。如果其中一个计划运行在很短的时间内就完成,
则另一计划可能只执行了一部分。

1- SQL Profile Finding (see explain plans section below)
--------------------------------------------------------
为此语句找到了性能更好的执行计划 2。选择以下 SQL 概要文件之一进行实施。
SQL profile 未自动创建。
Recommendation (estimated benefit: 16%)
---------------------------------------
- 考虑接受推荐的 SQL 概要文件。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285397, task_owner =>
'SYS', replace => TRUE);
Recommendation (estimated benefit: 99.72%)
------------------------------------------
- 考虑接受建议的 SQL 概要文件, 以便对此语句使用并行执行。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285397, task_owner =>
'SYS', replace => TRUE, profile_type => DBMS_SQLTUNE.PX_PROFILE);
与 DOP 288 并行执行此查询会使 SQL 概要文件计划上的响应时间缩短 99.68%。但是, 启用并行执行时要付出一些代价。它将增加语句的资源消耗
(预计为 6.95%), 这会导致系统吞吐量降低。此外, 由于在非常短的持续时间内消耗了这些资源, 因此如果没有足够可用的硬件容量,
并发语句的响应时间将受到负面影响。

FINDINGS SECTION (2 findings)
-------------------------------------------------------------------------------
1- SQL Profile Finding (see explain plans section below)
--------------------------------------------------------
为此语句找到了性能更好的执行计划。
Recommendation (estimated benefit: 99.7%)
-----------------------------------------
- 考虑接受建议的 SQL 概要文件, 以便对此语句使用并行执行。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285373, task_owner =>
'SYS', replace => TRUE, profile_type => DBMS_SQLTUNE.PX_PROFILE);
与 DOP 288 并行执行此查询会使原始计划上的响应时间缩短 99.71%。但是, 启用并行执行时要付出一些代价。它将增加语句的资源消耗 (预计为
15.94%), 这会导致系统吞吐量降低。此外, 由于在非常短的持续时间内消耗了这些资源, 因此如果没有足够可用的硬件容量,
并发语句的响应时间将受到负面影响。
The following data shows some sampled statistics for this SQL from the past
week and projected weekly values when parallel execution is enabled.
Past week sampled statistics for this SQL

Recommendation
--------------
- 请考虑使用最佳平均用时为计划创建 SQL 计划基线。
execute dbms_sqltune.create_sql_plan_baseline(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285373, owner_name =>
'SYS', plan_hash_value => 2556778791);

FINDINGS SECTION (2 findings)
-------------------------------------------------------------------------------
1- Index Finding (see explain plans section below)
--------------------------------------------------
通过创建一个或多个索引可以改进此语句的执行计划。
Recommendation (estimated benefit: 99.69%)
------------------------------------------
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_0001002C on JC800.SCMCOMPLETION("INQURYNO","INQURY
TIMES");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_0001002D on JC800.SCMSUPPLIERRESOURCE("CLIENT","VE
NDORNO","SHORTNAME");
Rationale
---------
创建推荐的索引可以显著地改进此语句的执行计划。但是, 使用典型的 SQL 工作量运行 "访问指导"
可能比单个语句更可取。通过这种方法可以获得全面的索引建议案, 包括计算索引维护的开销和附加的空间消耗。
2- Restructure SQL finding (see plan 1 in explain plans section)
----------------------------------------------------------------
优化程序不能取消执行计划的行 ID 2 处的子查询的嵌套。
Recommendation
--------------
- 考虑用 "NOT EXISTS" 代替 "NOT IN", 或者确保已通过添加 "NOT NULL" 约束条件或 "IS NOT NULL"
谓词将 "NOT IN" 运算符的两边所使用的列声明为 "NOT NULL"。

Rationale
---------
创建推荐的索引可以显著地改进此语句的执行计划。但是, 使用典型的 SQL 工作量运行 "访问指导"
可能比单个语句更可取。通过这种方法可以获得全面的索引建议案, 包括计算索引维护的开销和附加的空间消耗。

FINDINGS SECTION (3 findings)
-------------------------------------------------------------------------------
1- Statistics Finding
---------------------
尚未分析表 "JC800"."MLDTEMP1"。
Recommendation
--------------
- 考虑收集此表的优化程序统计信息。
execute dbms_stats.gather_table_stats(ownname => 'JC800', tabname =>
'MLDTEMP1', estimate_percent => DBMS_STATS.AUTO_SAMPLE_SIZE,
method_opt => 'FOR ALL COLUMNS SIZE AUTO');
Rationale
---------
为了选择好的执行计划, 优化程序需要此表的最新统计信息。
2- SQL Profile Finding (see explain plans section below)
--------------------------------------------------------
为此语句找到了性能更好的执行计划。
SQL 概要文件未自动创建, 因为优化程序统计信息已陈旧或缺失。在创建 SQL 概要文件前, 应先解决基本优化程序统计信息的问题。
Recommendation (estimated benefit: 99%)
---------------------------------------
- 考虑接受推荐的 SQL 概要文件。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285328, task_owner =>
'SYS', replace => TRUE);
Validation results
------------------
已对 SQL profile 进行测试, 方法为执行其计划和原始计划并测量与计划相对应的执行统计信息。如果其中一个计划运行在很短的时间内就完成,
则另一计划可能只执行了一部分。

1. the original plan 的统计信息是 10 执行的平均值。
2. the SQL profile plan 的统计信息是 10 执行的平均值。
3- Alternative Plan Finding
---------------------------
通过搜索系统的实时和历史性能数据找到了此语句的某些替代执行计划。
The following table lists these plans ranked by their average elapsed time.
See section "ALTERNATIVE PLANS SECTION" for detailed information on each
plan.

Information
-----------
- 因为找不到原始计划的任何执行历史记录, SQL 优化指导无法确定这些执行计划中是否有一些执行计划优于原始计划。但是,
如果您知道某个替代计划优于原始计划, 可以为该替代计划创建 SQL 计划基线。这将指示 Oracle 优化程序在将来优先于任何其他选择来选取它。
execute dbms_sqltune.create_sql_plan_baseline(task_name =>

--------------------------------------------------
通过创建一个或多个索引可以改进此语句的执行计划。
Recommendation (estimated benefit: 96.27%)
------------------------------------------
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010005 on JC800.PURDOCHEADER("VENDORNO","CLIENT"
,"VALIDITYENDPERIOD");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010006 on JC800.PURDOCITEM("PLANT","MTLNO","PURD
OCDELETIONINDIC","PURDOCITEMCTG","CLIENT","PURDOCNO","PURDOCLINENO");
Rationale
---------
创建推荐的索引可以显著地改进此语句的执行计划。但是, 使用典型的 SQL 工作量运行 "访问指导"
可能比单个语句更可取。通过这种方法可以获得全面的索引建议案, 包括计算索引维护的开销和附加的空间消耗。

--------------------------------------------------
通过创建一个或多个索引可以改进此语句的执行计划。
Recommendation (estimated benefit: 84.95%)
------------------------------------------
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index REPDBNEW.IDX$$_00010013 on
REPDBNEW.FXA_ZJGC_TEMP3("ORDERNO","YEARFLAG","CLIENT","COMPANYCODE");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index REPDBNEW.IDX$$_00010014 on
REPDBNEW.FXA_ZJGC_TEMP10("ORDNO","CLIENT");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index REPDBNEW.IDX$$_00010016 on
REPDBNEW.FXA_ZJGC_TEMP14("CLIENT","ORDNO","COMPANYCODE","PURDOCNO");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010017 on JC800.PURDOCHEADER("CLIENT","COMPANYCO
DE","PURDOCNO","ORDTYPE");
Rationale
---------
创建推荐的索引可以显著地改进此语句的执行计划。但是, 使用典型的 SQL 工作量运行 "访问指导"
可能比单个语句更可取。通过这种方法可以获得全面的索引建议案, 包括计算索引维护的开销和附加的空间消耗。

FINDINGS SECTION (4 findings)
-------------------------------------------------------------------------------
1- SQL Profile Finding (see explain plans section below)
--------------------------------------------------------
为此语句找到了性能更好的执行计划。
SQL profile 未自动创建, 因为经验证可获得的收益太少。
Recommendation (estimated benefit: 28.81%)
------------------------------------------
- 考虑接受推荐的 SQL 概要文件。
execute dbms_sqltune.accept_sql_profile(task_name =>
'SYS_AUTO_SQL_TUNING_TASK', object_id => 285266, task_owner =>
'SYS', replace => TRUE);
Validation results
------------------
已对 SQL profile 进行测试, 方法为执行其计划和原始计划并测量与计划相对应的执行统计信息。如果其中一个计划运行在很短的时间内就完成,
则另一计划可能只执行了一部分。
Original Plan With SQL Profile % Improved
------------- ---------------- ----------
Completion Status: COMPLETE COMPLETE

Executions: 1 1
2- Index Finding (see explain plans section below)
--------------------------------------------------
通过创建一个或多个索引可以改进此语句的执行计划。
Recommendation (estimated benefit: 76.11%)
------------------------------------------
- 考虑运行访问指导以改进物理方案设计或者创建推荐的索引。如果选择创建推荐的索引, 请考虑删除索引
"JC800"."BDMWORKCENTERHEADER_WKC", 因为它是推荐的索引的前缀。
create index JC800.IDX$$_00010001 on JC800.BDMWORKCENTERHEADER("WORKCENTER"
,"PLANT");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010002 on JC800.APMACTUALSEQDATAITEM(TO_CHAR("SC
ANDATE",'yyyy-MM-dd'));
Rationale
---------
创建推荐的索引可以显著地改进此语句的执行计划。但是, 使用典型的 SQL 工作量运行 "访问指导"
可能比单个语句更可取。通过这种方法可以获得全面的索引建议案, 包括计算索引维护的开销和附加的空间消耗。
3- Restructure SQL finding (see plan 1 in explain plans section)
----------------------------------------------------------------
谓词 TO_CHAR("APMACTUALS1_"."SCANDATE",'yyyy-MM-dd')>='2017-01-05' (在执行计划的行 ID
13 处使用) 包含索引列 "SCANDATE" 的表达式。此表达式使优化程序无法选择表 "JC800"."APMACTUALSEQDATAITEM"
的索引。
Recommendation
--------------
- 将谓词重写为等价型以便使用索引。或者, 对此表达式创建基于函数的索引。
4- Alternative Plan Finding
---------------------------
通过搜索系统的实时和历史性能数据找到了此语句的某些替代执行计划。
The following table lists these plans ranked by their average elapsed time.
See section "ALTERNATIVE PLANS SECTION" for detailed information on each
plan.
id plan hash last seen elapsed (s) origin note
-- ---------- -------------------- ------------ --------------- --------------
1 4104233932 2017-02-15/00:00:14 1.617 Cursor Cache original plan
2 3793614319 2017-02-15/00:02:14 1.680 Cursor Cache
Information
-----------
- 根据每次执行的用时, 原始计划可能具有最佳性能。但是, 如果您知道某个替代计划优于原始计划, 可以为该替代计划创建 SQL 计划基线。这将指示
Oracle 优化程序在将来优先于任何其他选择来选取它。

FINDINGS SECTION (2 findings)
-------------------------------------------------------------------------------
1- Index Finding (see explain plans section below)
--------------------------------------------------
通过创建一个或多个索引可以改进此语句的执行计划。
Recommendation (estimated benefit: 68.67%)
------------------------------------------
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010042 on JC800.APMACTUALSEQDATAITEM("CLIENT","S
CANTIME");
- 考虑运行可以改进物理方案设计的访问指导或者创建推荐的索引。
create index JC800.IDX$$_00010043 on JC800.BDMWORKCENTERHEADER("OBJECTID");
Rationale
---------
创建推荐的索引可以显著地改进此语句的执行计划。但是, 使用典型的 SQL 工作量运行 "访问指导"
可能比单个语句更可取。通过这种方法可以获得全面的索引建议案, 包括计算索引维护的开销和附加的空间消耗。
2- Alternative Plan Finding
---------------------------
通过搜索系统的实时和历史性能数据找到了此语句的某些替代执行计划。
The following table lists these plans ranked by their average elapsed time.
See section "ALTERNATIVE PLANS SECTION" for detailed information on each
plan.

Information
-----------
- 根据每次执行的用时, 原始计划可能具有最佳性能。但是, 如果您知道某个替代计划优于原始计划, 可以为该替代计划创建 SQL 计划基线。这将指示
Oracle 优化程序在将来优先于任何其他选择来选取它。
