Hi,
Be carefull about the max log size It's not 5,5GB but only 5500MB so if you
convert MB to GB, the maximum size is 5,3GB.
When your log space is 5500MB and full, you have to restore the database
because you can't extend the log space.
Since our database is more than 60GB, we must use rollforward mode because
full database backup is too long.
We are in TSM 4.1.4.1 and there is a bug with incremental database backup .
The log space doesn't clear every time when DB backup ends.
Now we upgrade to TSM 4.2 and the first server is OK.
Regards,
Alain Gourves

Objet : Recovery log space spikes
The maximum size of the recovery log is 5.5GB, my recovery log is 4.5 GB
now and I have just recently increased it 1GB from 3.5GB. It filled up
again last night. My database is 59.5 GB. Could I have a problem that is
causing my recovery log to fill up or is this normal for this size of
database?
I am running TSM 3.7.4 on OS390 R 2.10.
I have been testing TSM 4.1.4 and am planning to go to the new release in
the next few weeks, could this help the situation?
Below shows the past three days monitoring.
