Re: DB Backup in v5 TSM (5.1.1.6, 5.1.5.2, 5.1.5.4)

My database saves at about 22,000,000 pages an hour. I have taken the
messages from the log and they are consistently the same. I do not know
what is causing this. There were some performance problems with mirrored
databases, but I thought they were fixed at your level.

Subject: DB Backup in v5 TSM (5.1.1.6, 5.1.5.2, 5.1.5.4)
I have a strange problem that I have been working with IBM on, but was told
it's "working as designed". I have a new TSM server, which started life as
5.1.1.6, upgraded to 5.1.5.2 at IBM's request, then just did 5.1.5.4 today
after seeing it had been released. I back up the database, which is only
124000 pages since it is a new server. It backs up the first 90000 pages in
a couple of minutes. The last 34000 pages take over an hour. While this is
happening, there is very little CPU and I/O going on. I have tried the
database on SCSI, and on FastT700, the backup file on each, etc. I can make
it go away temporarily if I unload and reload, but once this database gets
bigger, that will not be an option. Any ideas? Thanks.
