CAD service logging repeatedly during backups?


Have an odd issue that I am sure has a simple solution.
I have a Linux client that during its backup windows the CAD services appears to continuously poll the TSM server, and log the action creating a huge log file. It starts when the scheduler cranks up and continues till 8am then stops.
Any ideas?

The scheduler queries the server every time CAD starts it.
CAD starts the scheduler when CAD starts, and repeats every QUERYSCHEDPERIOD.

Check to see if CAD is restarted often, you can use this command to see how often CAD is started/restarted:
cd /opt/tivoli/tsm/client/ba/bin
grep "Dsmcad is working in" dsmwebcl.log


I only see "Dsmcad is working in" occurring once last week:
06/07/2017 11:53:36 (dsmcad) Dsmcad is working in Webclient Schedule mode.

no occurrence after that

And how often does the scheduler query the server? In your earlier post, I see once in the evening and once in the morning, I'm suspecting there may be more between those 2 instances?

grep "Querying server for next scheduled event" dsmsched.log

Check dsmwebcl.log, just in case there are errors reported for CAD which would cause it to keep waking up the scheduler.

Also, it would be worth while to upgrade that client to 7.1.6 (or 8.1.0), just in case it's a defect. It would also bring you back into a support release.


This still continues, and I have recreated it by pointing more Linux clients to the new server. It has to be something related to the configuration on the new TSM server. Nothing on the clients changed except the server name in the dsm file and restarting the cad service.


I went through that, I even did a export server to the new tsm server. I guess I need to open a ticket with IBM, just seems like this should be something simple.
