Hi Mark,

I had a problem like this a few months back - waited  about an
hour for the server to start up properly - got to exactly the
same place yours came - after I halted it a 2nd time it came up
relatively quickly - about 20 minutes - I think the fact that
you have an 11Gig recovery log volume will contribute quite a
lot to the time it takes.
We have a 6gig rcvry log and once the log gets full it takes
quite long as I've stated.
The next time it happens the best to do is NOT to halt your
server but to keep it going - all client transactions will
fail because the recvry log is full - but that is fine - then
you just start a database backup from the MVS/TSO console and
wait for it to complete. There is an undocumented command
'ckpt force' - which normally clears up the log in critical
situations like this...

Cheers
Christo

This morning we noticed our TSM recovery log was ~97-100% full.
The server was still up but we couldn't log in. We halted the server,
increased the recovery log, and are trying to bring the server back up.

The problem is the server is stuck in Recovery log undo pass in progress.

10.36.06 STC24351  ANR0900I Processing options file dsmserv.opt.

10.36.07 STC24351  ANR0990I Server restart-recovery in progress.

10.36.30 STC24351  ANR0200I Recovery log assigned capacity is 11780
megabytes.
10.36.30 STC24351  ANR0201I Database assigned capacity is 53728 megabytes.

10.36.30 STC24351  ANR0306I Recovery log volume mount in progress.

10.44.07 STC24351  ANR0353I Recovery log analysis pass in progress.

11.57.38 STC24351  ANR0354I Recovery log redo pass in progress.

12.52.38 STC24351  ANR0355I Recovery log undo pass in progress.

12.52.40 STC24351  ANR0362W Database usage exceeds 88 %% of its assigned
capacity

Can anyone please advise?
