I think, the problem is Open APAR IC48382, which causes the significant
performance degradation. We start backup stgpool xy to copypool, and 4
hours later we get either ANR2111W (There is no data to process for
stgpool xy) or the backup process starts. The backup process itself is
very slow, seems to hang. Very annoying ...

Hi Thomas!
APAR IC47731 was fixed in patch level 5.3.2.3 and IC45931 was fixed in
5.3.2.1. The most recent patch level is 5.3.2.4 and your version can be
downloaded from
ftp://ftp.software.ibm.com/storage/tivoli-storage-management/patches/ser
ver/Linux/5.3.2.4/s390x/
IBM just released a new client maintenance level and this probably means
we have to wait a few months before a server maintenance release will be
made available.
In your case, I wouldn't wait for it and use the 5.3.2.4 patch release.
Patch releases tend to be much more stable that they were in the past.

Subject: Prognosis for APAR IC45931

We are running a mainframe Linux TSM server that is nearly out of CPU
capacity. We would very much like to move to a code level with the fix
for APAR IC47731, which causes a major waste of CPU capacity in
mainframe Linux environments. At the moment, all levels with that fix
suffer from the open APAR IC45931, which causes performance degradation
for 'backup stgpool' processes reading from sequential storage pools.
Since we already spend several hours per day running this type of
process, this APAR would be a major problem for us.

Does anyone know when there is likely to be a maintenace level that
fixes both APAR's?
