I've found  that keeping the log in ROLLFORWARD mode is best with the
backup trigger set to 80%  --- this way, should the log receive a great
deal of hits during any 12 hour period, the trigger will start a backup of
the log to tape. But I also have ADSM set to create full backups of the
database twice daily (that 12 hour period referenced in the previous
sentence), so the chances of it ever reaching the 80% mark are possible,
but not likely (learned the hard way on that one)....

Until today my logs had been fine and I was running my DB backup on a
scedule
once a day - full backup - no incremental.
After reading, I turned on the DBB trigger so that my log would empty out
when it was full -- my question is I'm not real clear on what I am gaining
by
having the DB trigger on or not?  Also, What does IBM recommend -
Set LOGM - Rollforward or Normal?
Thanks, Gail
