Which goes to show that you simply *must* run a complete expiration on a regular basis. If your current schedule doesn't allow it, you need to shove the start time for events until you *do* have a window. In my experience, a fair percentage of heavily-used/heavily-abused TSM servers that fail to run properly often do so because of incomplete expirations. -- Mark Stapleton ([EMAIL PROTECTED])
Re: Expire inventory (or audit license) hangs migrations and back ups
OK, now is question, how can I recognize hanging client session? (There is about 150 sessions at the time) I did "q sess" to file last time it happens, but all session were at "Run" state. In addition ... when I recognize it and cancel it, will the client reestablish session with server to end up backup? I see no good solution for this situation in automated manner (this is what I need), except of prevent it - this means write script to test if no client sessions are started at the time, disable clients, start expiration, and past it stops, enable clients. Any other idea?

I have seen this too a few days ago on my AIX server, running TSM 4.2.2.0. It looks like some kind of deadlock on a logpage. You will see that the expire inventory is just hanging and that one of your backup sessions is hanging too. You don't have to recycle the server though. As soon as you cancel the hanging client session, the expire inventory process continues. I haven't seen an APAR or fix for it, but since Tivoli implemented a the command SHOW LOGPINNED in 4.2.2.1 I think it's a known problem.

Re: Expire inventory (or audit license) hangs migrations and back ups
I had that problem with expiration - my mail server kept pinning the process - When it finally ran to completion it took 4-5 days, and expired 16M files. Good luck!

I'm shutting down all other activity on the server over a 24 hour period this weekend to see if we can force a full expiration and hopefully that will alleviate the symptoms a bit. -Original Message- From: Loon, E.J. van - SPLXM [mailto:[EMAIL PROTECTED]] Sent: Thursday, May 16, 2002 6:43 AM To: [EMAIL PROTECTED] Subject: Re: Expire inventory (or audit license) hangs migrations and back ups Hi Tom!
