Oracle中查看慢查询进度的脚本分享,本文给出了2个实现脚本,直接给出的代码

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;
