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;
