Still getting java.lang.OutOfMemoryError whatever the value of 'Maximum Memory in MB'

Question & Answer


TM1 Web or TM1 Application Web are getting unresponsive and Planning Analytics logs contain some errors java.lang.OutOfMemoryError. In Cognos Configuration, the parameter /Environment /TM1 Applications /Maximum Memory in MB has been increased a lot, but Java Out Of Memory errors are still happening the same way, with no improvement at all.


In previous versions, the default provided application server was Tomcat and the java heap was controlled by parameter 'Maximum Memory in MB' in /Environment /TM1 Applications.

But now, with Planning Analytics, the default provided application server is Websphere Liberty, and so the java memory is controlled by another parameter in Cognos Configuration :

/Environment /IBM Cognos TM1 Services /IBM Cognos TM1 /Maximum memory for Websphere Liberty Profile in MB

Increase this parameter instead.
