[ADSM-L] Including logs in DB2 backups
2011-02-23 14:17:09
Some months ago I reported that some of the DB2 servers at our site were
retrieving
archived files during database backups. The TSM server ended up cancelling at
least
one and sometimes more than one of our offsite tape reclamation processes to
make
tape drives available for the retrieve operations. I got a response from Michael
Garnebode explaining that the fix was to put "exclude logs" in the configuration
files for DB2 backups. When I asked our DBAs to do this I found out that
including
the logs in DB2 backups was a deliberate choice which they were very reluctant
to
give up. At the time I was willing to settle for a compromise: keep including
the
logs but reschedule some DB2 backups so that there was never more than one
concurrent
retrieve, and never more than one reclamation process cancelled. The TSM
workload
has increased since then, and I would rather not have any reclamation processes
cancelled on a routine basis. My impression is that the "include logs" option is
completely pointless in a TSM environment. Is this correct?
