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 ));
