Oracle中查看慢查询进度的脚本分享

oracle一个大事务的sql往往不知道运行到了哪里,可以使用如下sql查看执行进度。

set linesize 400;
set pagesize 400;
col sql_text format a100;
col opname format a15;
select se.sid,
         opname,
         trunc (sofar / totalwork * 100, 2) pct_work,
         elapsed_seconds elapsed,
         round (elapsed_seconds * (totalwork - sofar) / sofar) remain_time,
         sql_text
    from v$session_longops sl, v$sqlarea sa, v$session se
   where sl.sql_hash_value = sa.hash_value
         and sl.sid = se.sid
         and sofar != totalwork
order by start_time;

或者

set linesize 400;
set pagesize 400;
set long 4000;
col sql_fulltext format a100;
col opname format a15;
select se.sid,
         opname,
         trunc (sofar / totalwork * 100, 2) pct_work,
         elapsed_seconds elapsed,
         round (elapsed_seconds * (totalwork - sofar) / sofar) remain_time,
         sql_fulltext
    from v$session_longops sl, v$sqlarea sa, v$session se
   where sl.sql_hash_value = sa.hash_value
         and sl.sid = se.sid
         and sofar != totalwork
order by start_time;
