Even better. Kill the OS process first, then kill the Session if still necessary.

Using 'Alter system kill session' to remove a session holding a lock has always been problematic in Oracle.

On occasion, PMON will *not* clean up the session, and a bounce of the database is required to remove the lock.

I've seen it happen on 3 OS's, and versions 7.0.16, 7.2, 7.3, 8.04. Not sure
about 8i.

You might also want to get the os pid from v$process before issuing the alter system kill session statement.
Then you can easily track the os process if needed.

Select p.spid
>From v$session s, v$process p
Where s.paddr = p.addr
And s.sid = &sid;

Yeah that will do. But you need to wait as Oracle will Rollback the changed
data and then rel the lock.

Hello all,

I want to remove lock on a Table by using this command:

Alter system kill session '&sid,&serial'

Is this enough or I have to do something else!
