Looking at v$session_wait is the correct way of troubleshooting any "no response" type of problems. But I suggest he look at that particular session's v$session_wait. Find the session in v$session first.

[B]程序死的时候,执行
select sid,event,p1,wait_time from v$session_wait
注意event为enqueue且wait_time为0的sid,看看是不是死了的程序的sid.
你对整个应用系统有没有了解, 我怀疑是其它的程序锁住了tbname没有及时释放。 [/B] |
