The task running the Vantage Web UI is getting a java OutOfMemoryError condition.
The CA Vantage WEBUI returns the following messages:
JVMDUMP039I Processing dump event "systhrow", detail "java/lang/OutOfMemoryError" at 2016/01/14 17:57:51 - please wait.
JVMDUMP032I JVM requested System dump using 'JVM.TDUMP.VANWEBUI.D160114.T175751' in response to an event
This means there was too much workload going on the WEBUI and the JVM ran out of memory in its memory heap.
The solution is to increase JVM memory heap for WEBUI JVM.
This requires to edit VANWEBUI job (usually found in CCTUSAMP) and edit the following line:
IJO="-Xms128m -Xmx512m" to higher values like IJO="-Xms800m -Xmx800m"
Preferably both values should be the same. Sometimes there are problems when setting higher values. We cannot influence this as this has something to do with IBM JVM, and CA Vantage team does not have control over it. For 31bit JVM the theoretical limit is 2G of memory.
Other solution is to add the following line after the last line:
This should disallow other JVM application to use memory of the WEBUI.
As always, please contact CA Technologies support for CA Vantage if you have further questions.
