SQL Monitor Report

1. SQL Monitor简介

Oracle Database 11g中,系统自动监控符合以下条件的SQL,并收集执行时的细节信息:
1)采用并行方式执行

2)单次执行消耗的CPUIO超过5

3)通过使用/* +MONITOR*/  HINT的语句

系统收集的SQL信息会存储在V$SQL_MONITORV$SQL_PLAN_MONITOR视图中

2. SQL Monitor 参数设置

STATISTICS_LEVEL设置为:'TYPICAL'(缺省)或者 'ALL'

CONTROL_MANAGEMENT_PACK_ACCESS设置为:'DIAGNOSTIC+TUNING'

3. SQL Monitor report获取方法

SQL Monitoring可以采用以下3种方式展现:

1EMPerformance  ——>右下角的SQL Monitoring ——>Monitored SQL Executions

2SQL DeveloperTools ——>Monitor SQL

3DBMS_SQLTUNE ——> DBMS_SQLTUNE.report_sql_monitor

其报告格式有:'TEXT''HTML''XML' 'ACTIVE',其中'ACTIVE'只在11g R2以后才支持,使用HTMLFlash的方式显示动态的报告,需要从oracle官网读取相关联的JavascriptFlash

备注:

如果不能连到Internet又想看ACTIVE Report可以下载相关的库文件到本地的HTTP服务器上,然后用BASE_PATH来制定库文件的位置。

在本地HTTP服务器上创建目录,然后下载下面的文件:

mkdir -p /var/www/html/sqlmon

cd /var/www/html/sqlmon

wget --mirror --no-host-directories --cut-dirs=1 http://download.oracle.com/otn_software/emviewers/scripts/flashver.js

wget --mirror --no-host-directories --cut-dirs=1 http://download.oracle.com/otn_software/emviewers/scripts/loadswf.js

wget --mirror --no-host-directories --cut-dirs=1 http://download.oracle.com/otn_software/emviewers/scripts/document.js

wget --mirror --no-host-directories --cut-dirs=1 http://download.oracle.com/otn_software/emviewers/sqlmonitor/11/sqlmonitor.swf

在调用函数时加上参数,比如:base_path => 'http://ipaddr/sqlmon'

 

 

4.          SQL Monitor report生成实例

语法:

DBMS_SQLTUNE.REPORT_SQL_MONITOR()

 

FUNCTION REPORT_SQL_MONITOR RETURNS CLOB

 Argument Name                  Type                    In/Out Default?

 ------------------------------ ----------------------- ------ --------

 SQL_ID                         VARCHAR2                IN     DEFAULT

 TYPE                           VARCHAR2                IN     DEFAULT

 SQL_PLAN_HASH_VALUE            NUMBER                  IN     DEFAULT

4.1 Text文本格式

1)  Sqlplus 参数设置查看


show parameter statistics_level;

NAME                                 TYPE        VALUE

------------------------------------ ----------- ------------------------------

statistics_level                     string      TYPICAL


show parameter CONTROL_MANAGEMENT_PACK_ACCESS;

NAME                                 TYPE        VALUE

------------------------------------ ----------- ------------------------------

control_management_pack_access       string      DIAGNOSTIC+TUNING

2)  执行模拟SQL

[oracle@node4 sqlmonitor]$ sqlplus -S /nolog

conn /as sysdba;

select /* +moniotr*/* from scott.dept where deptno<=30;

 

             DEPTNO DNAME          LOC

---------- -------------- -------------

        10 ACCOUNTING     NEW YORK

        20 RESEARCH       DALLAS

        30 SALES          CHICAGO

3)  v$sql_monitor获取模拟SQL信息

col sql_text for a60;

set line 200;

set pagesize 20000;

 

select sql_id,sql_text from v$sql_monitor where sql_text like '%scott.dept%';

 

SQL_ID        SQL_TEXT

------------- ------------------------------------------------------------

74qqqwntwzxb1 select /*+ Monitor*/ * from scott.dept where deptno=10

4)  生成text类型报告

SET LONG 1000000

SET LONGCHUNKSIZE 1000000

SET LINESIZE 1000

SET PAGESIZE 0

SET TRIM ON

SET TRIMSPOOL ON

SET ECHO OFF

SET FEEDBACK OFF

spool report_sql_monitor_text.txt

SELECT DBMS_SQLTUNE.REPORT_SQL_MONITOR(

  SQL_ID       => '74qqqwntwzxb1',

  TYPE         => 'TEXT',

  REPORT_LEVEL => 'ALL') AS REPORT

FROM dual;

spool off

 

5)  展示报告内容

 

4.2 HTML格式

1)生成HTML类型报告

SET LONG 1000000

SET LONGCHUNKSIZE 1000000

SET LINESIZE 1000

SET PAGESIZE 0

SET TRIM ON

SET TRIMSPOOL ON

SET ECHO OFF

SET FEEDBACK OFF

 

spool report_sql_monitor_html.html

SELECT DBMS_SQLTUNE.REPORT_SQL_MONITOR(

  SQL_ID       => '74qqqwntwzxb1',

  TYPE         => 'HTML',

  REPORT_LEVEL => 'ALL') AS REPORT

FROM dual;

spool off

 

2html类型报告展示


4.3 Active格式

如不能联网,需要下载相应的flash组件、脚本,详细见SQL Monitor report获取方法

1active类型报告生成

SET LONG 1000000

SET LONGCHUNKSIZE 1000000

SET LINESIZE 1000

SET PAGESIZE 0

SET TRIM ON

SET TRIMSPOOL ON

SET ECHO OFF

SET FEEDBACK OFF

 

spool report_sql_monitor_active.html

SELECT DBMS_SQLTUNE.REPORT_SQL_MONITOR(

  SQL_ID       => '74qqqwntwzxb1',

  TYPE         => 'ACTIVE',

  REPORT_LEVEL => 'ALL',

  BASE_PATH    => 'http://ipaddr/sqlmon') AS report

FROM dual;

spool off

 

2active类型报告展示

 

可以通过启动http服务,将文件放置在发布目录下,通过http://ipaddr/sqlmon/report_sql_monitor_active.html形式查看(需下载相应的脚本和组件)


或者拿到windows本地查看


5.          SQL Monitor report其他方法使用

1DBMS_SQLTUNE.REPORT_SQL_MONITOR_LIST


FUNCTION REPORT_SQL_MONITOR_LIST RETURNS CLOB
 Argument Name                  Type                    In/Out Default?
 ------------------------------ ----------------------- ------ --------
 SQL_ID                         VARCHAR2                IN     DEFAULT
 SESSION_ID                     NUMBER                  IN     DEFAULT
 SESSION_SERIAL                 NUMBER                  IN     DEFAULT
 INST_ID                        NUMBER                  IN     DEFAULT
 ACTIVE_SINCE_DATE              DATE                    IN     DEFAULT
 ACTIVE_SINCE_SEC               NUMBER                  IN     DEFAULT
 LAST_REFRESH_TIME              DATE                    IN     DEFAULT
 REPORT_LEVEL                   VARCHAR2                IN     DEFAULT
 AUTO_REFRESH                   NUMBER                  IN     DEFAULT
 BASE_PATH                      VARCHAR2                IN     DEFAULT
 TYPE                           VARCHAR2                IN     DEFAULT

需要
Oracle 11g R2以上版本。此函数用于产生一个对监控SQL的汇总页,类似于EM中的“Monitored SQL Executions”。

常用参数:TYPEREPORT_LEVEL,用法与REPORT_SQL_MONITOR类似。

例如:

conn /as sysdba;
SET LONG 1000000
SET LONGCHUNKSIZE 1000000
SET LINESIZE 1000
SET PAGESIZE 0
SET TRIM ON
SET TRIMSPOOL ON
SET ECHO OFF
SET FEEDBACK OFF
SPOOL REPORT_SQL_MONITOR_LIST.HTML
SELECT dbms_sqltune.report_sql_monitor_list(
  type         => 'HTML',
  report_level => 'ALL') AS report
FROM dual;
SPOOL OFF



2DBMS_SQLTUNE.REPORT_SQL_DETAIL


FUNCTION REPORT_SQL_DETAIL RETURNS CLOB
 Argument Name                  Type                    In/Out Default?
 ------------------------------ ----------------------- ------ --------
 SQL_ID                         VARCHAR2                IN     DEFAULT
 SQL_PLAN_HASH_VALUE            NUMBER                  IN     DEFAULT
 START_TIME                     DATE                    IN     DEFAULT
 DURATION                       NUMBER                  IN     DEFAULT
 INST_ID                        NUMBER                  IN     DEFAULT
 DBID                           NUMBER                  IN     DEFAULT
 EVENT_DETAIL                   VARCHAR2                IN     DEFAULT
 BUCKET_MAX_COUNT               NUMBER                  IN     DEFAULT
 BUCKET_INTERVAL                NUMBER                  IN     DEFAULT
 TOP_N                          NUMBER                  IN     DEFAULT
 REPORT_LEVEL                   VARCHAR2                IN     DEFAULT
 TYPE                           VARCHAR2                IN     DEFAULT
 DATA_SOURCE                    VARCHAR2                IN     DEFAULT
 END_TIME                       DATE                    IN     DEFAULT
 DURATION_STATS                 NUMBER                  IN     DEFAULT
需要
Oracle 11g R2以上版本。此函数用于根据各种条件参数(包括:start_time, end_time, duration, inst_id, dbid, event_detail, bucket_max_count, bucket_interval, top_n, duration_stats),产生比使用REPORT_SQL_MONITOR更加详细的SQL报告。

例如:


conn /as sysdba;
SET LONG 1000000
SET LONGCHUNKSIZE 1000000
SET LINESIZE 1000
SET PAGESIZE 0
SET TRIM ON
SET TRIMSPOOL ON
SET ECHO OFF
SET FEEDBACK OFF
SPOOL REPORT_SQL_DETAIL_HTML.HTML
SELECT dbms_sqltune.REPORT_SQL_DETAIL(SQL_ID   => '74qqqwntwzxb1',
                                 TYPE         => 'active',
                                 report_level => 'ALL') AS report
FROM dual;
SPOOL OFF

ERROR:
ORA-13971: Component "sql_detail" unknown
ORA-06512: at "SYS.DBMS_SYS_ERROR", line 95
ORA-06512: at "SYS.DBMS_REPORT", line 166
ORA-06512: at "SYS.DBMS_REPORT", line 612
ORA-06512: at "SYS.DBMS_REPORT", line 1079
ORA-06512: at "SYS.DBMS_REPORT", line 1135
ORA-06512: at "SYS.DBMS_SQLTUNE", line 20101
ORA-06512: at line 1
(上述错误在指定html格式,调整为active格式即可



可以针对topSQL

conn /as sysdba;
SET LONG 1000000
SET LONGCHUNKSIZE 1000000
SET LINESIZE 1000
SET PAGESIZE 0
SET TRIM ON
SET TRIMSPOOL ON
SET ECHO OFF
SET FEEDBACK OFF
SPOOL REPORT_SQL_DETAIL.HTML
SELECT dbms_sqltune.report_sql_detail(top_n        => 5,
                                 TYPE         => 'active',
                                 report_level => 'ALL') AS report
FROM dual;
SPOOL OFF
