Re: best way to avoid long rollback
It depends on the signal you use. A standalone "kill" or a "kill -15"
yes. That's called SIGTERM, all it does is send a termination signal to
the process.

So you are saying that issuing the server HALT command via console is no
different than the OS level kill?

It's in the manual as one of the proper ways to start/stop the server:
https://www.ibm.com/support/knowledgecenter/SSEQVQ_8.1.0/srv.install/t_srv_startsrv_autolnx-linux.html
If the wrapper was doing a "kill -9", that would be a completely different
ball of wax.

Re: best way to avoid long rollback
Hi Eric, Just like Zoltan said, you really need to prevent a kill of TSM. This will leave the DB2 database in an inconsistent state and thus result in a DB2 crash recovery which can indeed be a lengthy process. Just use a halt to stop TSM and the DB2 database will be closed properly.

Typically then shutdown with systemctl stop tsminst1. I think last time we stopped tsm about an hour after the db finished its backups. Likely restarted tsm about an hour after tsm stopped. It takes roughly and an hour for us to do all of the patching tripwire reboot etc that we do.

Re: best way to avoid long rollback
Out of curiosity, why do you do a "systemctl stop tsminst1" (which if I recall does a kill) vs just HALT the ISP server immediately after the DB backup finishes? Our patching takes about the same time (we do it monthly) since the IBM lin_tape drivers have to be removed before kernel patching and then reinstalled afterwards which adds to the time.

Re: best way to avoid long rollback
We are running rhel7 on a dell r730 and we just did a full and dbsnap...ususally take about 1.5h for both to complete. Typically then shutdown with systemctl stop tsminst1. I think last time we stopped tsm about an hour after the db finished its backups. Likely restarted tsm about an hour after tsm stopped. It takes roughly and an hour for us to do all of the patching tripwire reboot etc that we do.

Re: best way to avoid long rollback
I have to ask what OS/hardware/ISP are you running? What procedure are you using to prep for the OS patching (we stop client sessions/all admin processes - do a full DB backup - halt the server) Our offsite replica server is RHEL 7 on Dell R740xd with 192GB and 3TB SSD with the DB currently at 2.3TB used. We patch monthly and never had it take more than 15-minutes from OS reboot to ISP server being available! On Mon, Mar 11, 2019 at 11:41 AM J.

best way to avoid long rollback
We have a pair of tsm servers doing backup and replication. Each has a database over 1TB on ssd and 512G of memory Our organization likes to do os patch maintenance every 90d and doing this requires a stop and restart of db2. When would it be best to do maintenance to shorten the rollback time? I would think after completing the db backups. Last time we did maintenance about 1h after backups completed it took >2h for the db to come up. Thanks
