使用SQL获取ASH/ADDM/AWR报告

有时候想直接在SQLPLUS中看ASH/ADDM/AWR报告，用下面方法还是比较方便,

因为AWR数据在数据库中默认只保留7天，即使设置保留30天，可能有时候我们需要

进行性能对比分析需要保留时段之前的AWR，那么我们可以采用脚本定时将AWR报告

输出保存。

获取ASH报告

select output
from table(dbms_workload_repository.ash_report_text((select dbid from v$database),
1,
TO_DATE('20130712203500',
'YYYYMMDDHH24MISS'),
TO_DATE('20130712204600',
'YYYYMMDDHH24MISS')));

获取ADDM报告

select * from dba_advisor_tasks s order by s.created desc

set long 1000000 pagesize 0 longchunksize 1000

select dbms_advisor.get_task_report('ADDM:3620614489_1_25298') from dual;

获取AWR报告

SELECT SNAP_ID snapid FROM DBA_HIST_SNAPSHOT;

select output from
table(dbms_workload_repository.awr_report_text(
&dbid,
&inst_num,
&bid, &eid,
8 ));
