查看和修改AWR配置

作者:互联网

有时遇到系统遇到复杂问题,处理周期长,需要保留系统的快照周期,便于分析问题,这时,需要延长延长快照时间周期(默认一般是一周时间)。

一、查看当前AWR配置

10g版本中默认是保留7天,11g版本中默认保留8天,采集间隔是1小时,这个信息可以从DBA_HIST_WR_CONTROL视图中获得。

SQL> select * from dba_hist_wr_control;

      DBID     SNAP_INTERVAL       RETENTION          TOPNSQL        CON_ID
---------- -------------------- -------------------- -------------------- ----------
 2541626938  +00000 01:00:00.0   +00008 00:00:00.0    DEFAULT           0

参数说明:
snap_interval: 快照间隔,单位是分钟
retention: 快照保留周期,单位是分钟

SNAP_INTERVAL=+00000 01:00:00.0 表示采样间隔是1小时
RETENTION=+00008 00:00:00.0 表示采样数据保留期限是8天

二、调整AWR配置

可使用使用DBMS_WORKLOAD_REPOSITORY包中的MODIFY_SNAPSHOT_SETTINGS存储过程修改AWR配置。
DBMS_WORKLOAD_REPOSITORY包结构如附录【1】。

1、调整AWR产生 snapshot 的频率和保留策略

例:将采样间隔改为30 分钟,保留30天时间(注:单位都是为分钟):

SQL> exec  dbms_workload_repository.modify_snapshot_settings(interval=>30,  retention=>30*24*60);

PL/SQL procedure successfully completed.

验证修改结果:

SQL> select * from dba_hist_wr_control;

      DBID     SNAP_INTERVAL       RETENTION          TOPNSQL        CON_ID
---------- -------------------- -------------------- -------------------- ----------
 2541626938  +00000 00:30:00.0   +00030 00:00:00.0    DEFAULT           0

已将采样间隔改为30 分钟,保留时间修改为30天。

2、关闭AWR

把interval设为0则关闭自动捕捉快照

三、AWR相关内容补充

1、手工创建一个快照

SQL> exec DBMS_WORKLOAD_REPOSITORY.CREATE_SNAPSHOT ();

2、查看快照

SQL> select * from sys.wrh$_active_session_history

3、手工删除指定范围的快照

SQL> exec WORKLOAD_REPOSITORY.DROP_SNAPSHOT_RANGE(low_snap_id  => 11, high_snap_id => 26, dbid => 3561526973);

4、创建baseline

SQL> exec dbms_workload_repository.create_baseline  (56,59,'apply_interest_1')

5、删除baseline

SQL> exec DBMS_WORKLOAD_REPOSITORY.DROP_BASELINE(baseline_name  => ' apply_interest_1', cascade => FALSE);

6、生产AWR报告

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

AWR收集统计信息的特性受statistics_level影响,该参数有3个可选值。
BASIC:AWR统计信息收集和所有自我调整特性都被关闭
TYPICAL:数据库收集部分统计信息,这些信息为典型的数据库监控需要,默认设置
ALL:所有可能统计信息被收集
