How to set the location of Java dump files for TM1Web

Post by gtonkin » Tue Oct 06, 2015 6:15 pm

Saw this link on my IBM notifications today and thought it worth sharing.

Besides configuring the paths for the various Java dump files, it also shows you how to launch the Application configuration to tweak other settings.

Start the Tomcat Java configuration utility by running the following command:

Code: Select all

"C:\Program Files\IBM\Cognos\tm1_64\tomcat\bin\tomcat6w.exe" //ES//pmpsvc

Reason: Moved to Useful Code; as per Lotsaram's comments this one is potentially dangerous for the unaware.

Having been burnt by this I can vouch it is definitely worth it to change the default setting as the default sets the dump path to the install root. Should TM1 web crash and tomcat dumps a 20 GB dump file to c:\program files when you only have 10 GB free on C: you can rest assured this will effectively cripple all TM1 instances and everything else running on the box. Hell even if you have 50 GB free but this happens a few times in succession before anyone realizes and can clear the dump files then you will end up with the same result.

As most IT departments insist on a fairly lean C partition (especially for VM setup) then it pays to change this to a location where there is plenty of space.
Please place all requests for help in a public thread. I will not answer PMs requesting assistance.
