Re: Killed session

I have a similar issue on 9.2.0.7 SE on Solaris.

Long-idle sessions were killed weeks ago. They wouldn't go away, so the
corresponding shadow processes on Solaris were killed as well. These
processes are gone, the sessions are holding no locks, they have nothing in
v$transaction, but still they remain in v$session with status 'KILLED' (and
they count towards the max "sessions" parameter ...)

I've never seen sessions hang around (for a couple of weeks now) after the
corresponding shadow process was killed ... anyone seen anything similar ?
And if I missed something obvious : RTFM answers of course also much
appreciated :-)

mvg/regards

Jo

I have seen a very similar issue on  9.2.0.8 , Solaris 8, and it was a bug
that we had to patch for.

Check  metalink Bug #6279479  "Index Rollback taking too long to
complete/hang"  . I'm not sure if this is your issue, but it may be.
Unfortunately, the only way we had of clearing it was to shutdown the
database.

      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
