Oracle AWR速查
1.查看當(dāng)前的AWR保存策略
select * from dba_hist_wr_control;
DBID,SNAP_INTERVAL,RETENTION,TOPNSQL
860524039,+00 01:00:00.000000,+07 00:00:00.000000,DEFAULT
以上結(jié)果表示,每小時產(chǎn)生一個SNAPSHOT，保留7天
2.調(diào)整AWR配置
AWR配置都是通過dbms_workload_repository包進(jìn)行配置
2.1調(diào)整AWR產(chǎn)生snapshot的頻率和保留策略，如：如將收集間隔時間改為30 分鐘一次。并且保留5天時間（注：單位都是為分鐘）：
exec dbms_workload_repository.modify_snapshot_settings(interval=>30, retention=>5*24*60);
2.2關(guān)閉AWR,把interval設(shè)為0則關(guān)閉自動捕捉快照
2.3手工創(chuàng)建一個快照
exec DBMS_WORKLOAD_REPOSITORY.CREATE_SNAPSHOT ();
2.4 查看快照
select * from sys.wrh$_active_session_history
2.5手工刪除指定范圍的快照
exec WORKLOAD_REPOSITORY.DROP_SNAPSHOT_RANGE(low_snap_id => 22, high_snap_id => 32, dbid => 3310949047);
2.6創(chuàng)建baseline
exec dbms_workload_repository.create_baseline (56,59,'apply_interest_1')
2.7刪除baseline
exec DBMS_WORKLOAD_REPOSITORY.DROP_BASELINE(baseline_name => ' apply_interest_1', cascade => FALSE);
3.生產(chǎn)AWR報告
