Re: Killed session

I have a similar issue on 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 :-)

I have seen a very similar issue on , 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 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.
