If you run a database backup, does the log go down?
If it does not, you probably have a long transaction in the database. A
certain client is "pinning" the log.

Are you using "roll forward recovery"? From what you are saying it
appears so. I would recommend turning it off and using a
logmode=normal
which will commit recovery log transactions to the DB as they
complete
instead of every time the DB fills up.

Subject: 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.
