Hi List,
We have a number of TSM clients (5.5.2.0 on mostly Windows 2003 SP2) that
stop making forward progress in the busy part of the night, and are just
sitting in RecvW when we check in the morning.
These clients that aren't making progress appear to be involved as cause
or effect in the log pinning and getting to 80% full, and then dsmserv
starts killing the oldest session. (The cynic in me wonders if this pain
was added to get people to move from 5.5 to 6.x.)
For the problem sessions below, there is only one session per node, and
based on the received bytes count, appear to correspond to the data
session and not the meta-data session.
Stopping the backup on the client side 'dsmcutil q /name:"TSM Scheduler"',
and then running a manual "dsmc i" finishes a manual incremental (
typically) in under 5 minutes.
So far, I've upped the MAXNUMMP value for all the effected nodes from 2 to
5, and have remove "queryschedperiod 12" and "quiet yes" from the client
option set.
I have a PMR open with Tivoli support, but wanted to check with the list
to see if anyone has seen this particular weirdness before.
