RE: Killed session

First thing I'd look at is if a distributed transaction is in process. Look in dba_2pc_pending as the session may be looking for a foreign database that is where this session started. Otherwise you may have one of those instances where a database restart is the only way you'll clear the locks.

Subject: Killed session

Hi Listers,

Oracle 9.2.0.8 on Solaris 9

In one of my production database session was long running. Session was killed last night. Since then session is marked as KILLED in v$session. This killed session is holding locks on few tables and causing further problems.

USED_UBLK in v$transaction is constant at 287 since late last night.

I identified unix process and killed at os level two hours ago, still session would not go away. (os process is gone already)

What else should I be looking at? How do I get rid of KILLED session?

I do not have luxury to recycle database.

Your help is greatly appreciated.

Thanks
Mayen
