Oracle 12.2 physical standby备库收集AWR报告

原创 Oracle 作者:水逸冰 时间:2019-09-05 16:30:01 0 删除 编辑

Oracle 12.2 提供了收集备库AWR 的功能。

确定备库角色和打开状态

SQL> select inst_id, open_mode,   database_role from gv$database order by 1;

 

    INST_ID OPEN_MODE                        DATABASE_ROLE

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

           1 READ ONLY WITH APPLY             PHYSICAL STANDBY

 

On Primary (CDB) 执行解锁:

SQL> alter user sys$umf identified by   sysumf account unlock;

SYS$UMF 用户默认是locked 的;该用户具有Remote Management Framework (RMF) 有关的所有的视图和表的权限。

 

On Primary (CDB) 创建db_link

create database link   dblk_EMNBBETA_TO_EMNBBETAPDG01 CONNECT TO sys$umf IDENTIFIED BY sysumf using   'LTACTESTPDG01';

create database link   dblk_EMNBBETAPDG01_TO_EMNBBETA CONNECT TO sys$umf IDENTIFIED BY sysumf using   'LTACTEST';

 

RMF 拓扑结构中的所有节点必须有一个独一无二的名字,默认选择db_unique_name

On Primary CDB 执行) ,LTACTEST 是主库db_unique_name

exec dbms_umf.configure_node ('LTACTEST');

 

On Standby LTACTESTPDG01 是备库db_unique_name

exec dbms_umf.configure_node   ('LTACTESTPDG01','dblk_EMNBBETAPDG01_TO_EMNBBETA');

 

创建RMF 拓扑,On Primary

exec DBMS_UMF.create_topology   ('EMNBBETA_Topology');

 

验证目前为止的操作

set line 132

col topology_name format a15

col node_name format a15

 

select * from dba_umf_topology;

select * from dba_umf_registration;

 

For example

 

SQL> select * from dba_umf_topology;

 

TOPOLOGY_NAME         TARGET_ID TOPOLOGY_VERSION   TOPOLOGY_STATE

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

EMNBBETA_Topology     798157014                1 ACTIVE

 

SQL> select * from dba_umf_registration;

 

TOPOLOGY_NAME        NODE_NAME          NODE_ID  NODE_TYPE AS_SOURCE       AS_CANDIDATE_TA STATE

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

EMNBBETA_Topology    LTACTEST         798157014          0 FALSE           FALSE           OK

 

 

注册备库到RMF 拓扑中

SQL> exec DBMS_UMF.register_node   ('EMNBBETA_Topology', 'LTACTESTPDG01', 'dblk_EMNBBETA_TO_EMNBBETAPDG01',   'dblk_EMNBBETAPDG01_TO_EMNBBETA', 'FALSE', 'FALSE');

BEGIN DBMS_UMF.register_node   ('EMNBBETA_Topology', 'LTACTESTPDG01', 'dblk_EMNBBETA_TO_EMNBBETAPDG01',   'dblk_EMNBBETAPDG01_TO_EMNBBETA', 'FALSE', 'FALSE'); END;

ERROR at line 1:

ORA-15766: already registered in an RMF   topology

ORA-06512: at   "SYS.DBMS_UMF_INTERNAL", line 132

ORA-06512: at   "SYS.DBMS_UMF_INTERNAL", line 170

ORA-06512: at "SYS.DBMS_UMF", line   822

ORA-06512: at line 1

ORA-06512: at "SYS.DBMS_UMF", line   794

ORA-06512: at "SYS.DBMS_UMF", line   712

ORA-06512: at line 1

解决办法:

如果遇到了ORA-15766 ,那么就执行下面:

SQL> exec DBMS_UMF.unregister_node   ('EMNBBETA_Topology', 'LTACTESTPDG01');

 

PL/SQL procedure successfully completed.

如果遇到了 ORA-13519: Database id (1730117407) exists in the workload repository ,然后重新运行 DBMS_WORKLOAD_REPOSITORY.register_remote_database

exec DBMS_WORKLOAD_REPOSITORY.unregister_remote_database('LTACTESTPDG01' ,' EMNBBETA_Topology ',TRUE);

 

注册到AWR

exec   DBMS_WORKLOAD_REPOSITORY.register_remote_database(node_name=>'LTACTESTPDG01');

 

PL/SQL procedure successfully completed.

验证

set line 132

col topology_name format a20

col node_name format a15

SQL> select * from dba_umf_topology;

TOPOLOGY_NAME         TARGET_ID TOPOLOGY_VERSION   TOPOLOGY_STATE

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

EMNBBETA_Topology     798157014                6 ACTIVE

 

SQL>    select * from dba_umf_registration;

 

TOPOLOGY_NAME        NODE_NAME          NODE_ID  NODE_TYPE AS_SOURCE       AS_CANDIDATE_TA STATE

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

EMNBBETA_Topology    LTACTEST         798157014          0 FALSE           FALSE           OK

EMNBBETA_Topology    LTACTESTPDG01    524737559          0 FALSE           FALSE           OK

 

SQL> select * from dba_umf_service;

 

TOPOLOGY_NAME           NODE_ID SERVICE_ID

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

EMNBBETA_Topology     524737559 AWR

 

RMF 创建远程snapshot

SQL> exec dbms_workload_repository.create_remote_snapshot('LTACTESTPDG01');

 

PL/SQL procedure successfully completed.

如果遇到了 ORA-13516: AWR Operation failed: Remote source not registered for AWR ,手动切 2-3 个归档

alter system switch logfile;

 

收集备库AWR 报告

注意是 awrrpti.sql ,不是 awrrpt.sql

输入dbid 就可以了。

 

SQL> @?/rdbms/admin/awrrpti.sql
