session idle超过设置时间,状态为sniped (v$session).,然而OS下的process并不会释放,当session(user process) 再次与server process 通讯,将关闭相应的server process. What does 'SNIPED' status in v$session mean? When IDLE_TIME is set in the users' profiles or the default profile. This will kill the ...
When IDLE_TIME is set in the users' profiles or the default profile. This will kill the sessions in the database (status in v$session now becomes SNIPED) and they will eventually disconnect. It does not always clean up the Unix session (LOCAL=NO sessions). At this time all oracle resour...

一. Session状态说明 可以通过v$session视图的status列查看session的状态。关于该视图的使用,参考联机文档: V$SESSION http://download.oracle.com/docs/cd/E11882_01/server.112/e17110/dynviews_3016.htm#REFRN30223 STATUS VARCHAR2(8) Status of the session: ...
The following text includes several helpful queries that run against the v$active_session_history view. The first query, events_waits_hr_ask.sql, reports a list of resources that were in high demand in the last hour. This query does not reflect Idle wait events. ...
在Oracle 10G中,我们引入了AWR和ASH采样机制,有一个视图gv$active_session_history会每秒钟将数据库所有节点的Active Session采样一次,而dba_hist_active_sess_history则会将gv$active_session_history里的数据每10秒采样一次并持久化保存。基于这个特征,我们可以通过分析dba_hist_active_sess_history的Session采样情况,...
