[oracle] 查询历史会话、历史执行计划

1.查询历史连接信息
select *
from dba_hist_active_sess_history a
where a.SAMPLE_TIME BETWEEN
TO_DATE('2020-10-04 12:00:00', 'YYYY-MM-DD HH24:MI:SS') AND
TO_DATE('2020-10-04 13:00:00', 'YYYY-MM-DD HH24:MI:SS')

select *
from v$active_session_history D
WHERE d.SAMPLE_TIME BETWEEN
TO_DATE('2020-10-04 12:00:00', 'YYYY-MM-DD HH24:MI:SS') AND
TO_DATE('2020-10-04 13:00:00', 'YYYY-MM-DD HH24:MI:SS')

 
2.查询历史sql信息

select * from v$sqlarea where sql_text like '%%';

3.查询历史执行计划
select * from v$sql_plan;

如果缓存内查询不到，可以查询DBA_HIST_SQL_PLAN表
select * from DBA_HIST_SQL_PLAN;
