Oracle的AWR生產實踐一
一.AWR常用功能
1.Snapshot的管理
---------------------------------查詢具體快照信息:
SQL> select * from DBA_HIST_SNAPSHOT; SNAP_ID DBID INSTANCE_NUMBER STARTUP_TIME BEGIN_INTERVAL_TIME END_INTERVAL_TIME FLUSH_ELAPSED SNAP_LEVEL ERROR_COUNT ---------- ---------- --------------- -------------------------------------------------------------------------------- -------------------------------------------------------------------------------- -------------------------------------------------------------------------------- --------------------------------------- ---------- ----------- 1460 1435972043 1 23-12月-18 09.27.16.000 下午 23-12月-18 09.38.32.168 下午 23-12月-18 11.00.46.677 下午 +00000 00:00:01.3 1 0 1461 1435972043 1 02-1月 -19 08.56.09.000 下午 02-1月 -19 08.56.09.000 下午 02-1月 -19 09.04.22.484 下午 +00000 00:00:05.5 1 0 1459 1435972043 1 23-12月-18 09.27.16.000 下午 23-12月-18 09.27.16.000 下午 23-12月-18 09.38.32.168 下午 +00000 00:00:18.8 1 0
----------------------------------創建快照:
SQL> exec dbms_workload_repository.create_snapshot; PL/SQL procedure successfully completed
2.基線的設置
----------------------------------設置快照爲1459~1461的基線，基線名爲:test_baseline
SQL> exec dbms_workload_repository.create_baseline(start_snap_id=>1459,end_snap_id=>1461,baseline_name=>'test_baseline'); PL/SQL procedure successfully completed
3.所需空間開銷和設置
----------------------------------查看AWR配置情況:
SQL> col snap_interval for a20; SQL> col retention format a20; SQL> select * from dba_hist_wr_control; DBID SNAP_INTERVAL RETENTION TOPNSQL ---------- -------------------- -------------------- ---------- 1435972043 +00000 01:00:00.0 +00007 00:00:00.0 DEFAULT
SNAP_INTERVAL=+00000 01:00:00.0 表示採樣間隔是1小時。
RETENTION=+00007 00:00:00.0 表示採樣數據保留期限是7天。
----------------------------------如果修改爲30分鐘採樣一次，數據保留31天，可以如下設置:
SQL> exec dbms_workload_repository.modify_snapshot_settings(interval=>30,retention=>31*24*60); PL/SQL procedure successfully completed SQL> select * from dba_hist_wr_control; DBID SNAP_INTERVAL RETENTION TOPNSQL ---------- -------------------- -------------------- ---------- 1435972043 +00000 00:30:00.0 +00031 00:00:00.0 DEFAULT
4.AWR數據的遷移
(1)AW數據的導出，可以使用awrextr.sql這個自帶的腳本來導出

5.生成AWR相關的報告
@?/rdbms/admin/awrrpt.sql ----最常見的生成awr報告的方式
@?/rdbms/admin/awrsqrpt.sql ----生成awr報告中指定SQL_ID的執行計劃
@?/rdbms/admin/awrddrpt.sql ---比較兩個awr報告
@?/rdbms/admin/awrrpti.sql ----適用於rac環境
6.awr相關的視圖和基表
dba_hist_snapshot
dba_hist_sql_plan
dba_hist_wr_control
總結:分析AWR報告對於DBA而言是工作中的重要內容，就和醫院看病的化驗單一樣。
