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。

复制代码 代码如下:

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

复制代码 代码如下:

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;
