采样某瞬时SAMPLE_TIME或者某时间段内SAMPLE_TIME

1.采样某瞬时SAMPLE_TIME的SQL_ID||SQL_PLAN_HASH_VALUE、EVENT的活动会话分组

某个sample_time时间点查看该sample_time时间点的等待事件和相关SQL_ID、p1、p2等参数

set linesize 260 pagesize 10000

select sql_id, nvl(event,'on cpu') event,count(*),p1||'',p2||''

  from v$active_session_history a

 where sample_id=&sample_id

 group by sql_id, nvl(event,'on cpu'),p1||'',p2||''

 order by count(*) desc;
