Re: Korn Shell & Sqlplus

I must agree with Jared on this practice. By following this practice, you never bounce database to just get rid of hanging sessions holding locks as some listers are complaining about that they had to bounce database to get rid of hanging sessions becuase they killed process on database level first.

Stephane,

We will certainly disagree on that. I contend that you should *always* kill the process first. The reason being that using 'ALTER SYSTEM KILL SESSION' has a nasty habit of hanging sessions that are holding locks.

I've seen it happen on all versions from 7.0.16 - 8.1.6, on DG/UX, Windows NT 4.0 and Solaris 2.5 - 2.6.

It has become my habit to always kill the process ( if dedicated server ) or NT thread first. If the session still appears in v$session, use ALTER SYSTEM KILL SESSION to finish it off. Works every time.

Doing it Oracle's way has necessitated too many database bounces for my tastes.

Jared
