Oracle 查看 session 当前统计信息 脚本 说明

一.相关说明

当我们在一个session 上进行事务操作时,如果我们想查看这个事务的相关统计信息,那么可以通过v$mystat ,v$sysstat, v$sesstat, v$statname 字典来查看。 在Oracle 11g中,通过这2个视图,我么可以查看到588个相关的统计信息。


SQL> select * from v$version;BANNER--------------------------------------------------------------------------------Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit ProductionPL/SQL Release 11.2.0.1.0 - ProductionCORE    11.2.0.1.0      ProductionTNS for 64-bit Windows: Version 11.2.0.1.0 - ProductionNLSRTL Version 11.2.0.1.0 - ProductionSQL> SELECT COUNT (*)  2    FROM v$mystat vm, v$sysstat vs  3   WHERE vm.statistic# = vs.statistic#;  COUNT(*)----------       588

v$mystat 字典只能查看当前session 的信息,而v$sesstat 可以查看所有session 的信息,v$sysstat和v$statname 是对统计信息的一个说明。如果不是SYS 用户来执行,那么就需要单独的对这些用户进行赋权操作,具体命令如下:

 grant select on v_$mystat to anqing; grant select on v_$statname to anqing; grant select on v_$sesstat to anqing; grant select on v_$sysstat to anqing;


有关Oracle 视图的相关说明参考:

二.查看当前session 的统计信息:v$mystat v$sysstat

我们可以通过如果SQL 来查看当前session 的具体统计信息,从而来帮助我们分析SQL 语句:

http://www.cndba.cn/Dave/article/411

/* Formatted on 2012/6/25 10:57:20 (QP5 v5.185.11230.41888) */SELECT vm.sid, vs.name, vm.VALUE  FROM v$mystat vm, v$sysstat vs WHERE     vm.statistic# = vs.statistic#       AND vs.name IN              ('cleanouts only - consistent read gets',               'session logical reads',               'physical reads',               'physical reads direct',               'redo size');

这个操作需要注意相关的权限问题。

 

 

三.查看所有session的统计信息:v$sessstat  v$statname

 

/* Formatted on 2012/6/25 12:39:51 (QP5 v5.185.11230.41888) */SELECT a.sid, b.name, a.VALUE  FROM v$sesstat a, v$statname b WHERE     a.statistic# = b.statistic#       AND b.name IN              ('cleanouts only - consistent read gets',               'session logical reads',               'physical reads',               'physical reads direct',               'redo size');


这里我们也可以加上SID 条件,只查看某个session的的统计信息,获取SID的方法参考:

http://blog.csdn.net/tianlesoftware/article/details/7240085

 

SELECT a.sid, b.name, a.VALUE  FROM v$sesstat a, v$statname b WHERE     a.statistic# = b.statistic#       AND sid = 139       AND b.name IN              ('cleanouts only - consistent read gets',               'session logical reads',               'physical reads',               'physical reads direct',               'redo size');


四.所有的统计信息列表

            在Oracle 11gR2中总共有588个相关的统计,我们可以根据自己的需要来查看相关的信息,这588个统计的所有列表如下:

 http://www.cndba.cn/Dave/article/411http://www.cndba.cn/Dave/article/411
