Integration server is going down throwing java.lang.OutOfMemoryError: GC overhead limit exceeded

Question

I have several integration servers which are running on unix box. These servers pick data from a websphere queue and process them. One of the server is automatically going down giving java.lang.OutOfMemoryError:

GC overhead limit exceeded.

I want to increase the JVM parameter for this particular server on uinx. How can i do that? Is there any command to do so? Thanks a ton in advance.

Answer 1

You can also edit the Sandbox.cfg file to increase the memory parameter and run setupfile.cmd

Answer 2

If you check the startIntegrationServer.sh you can see the integration servers start with below arguments:

${JAVA} -classpath Foundation/jar/bootstrapper.jar ${AGENT_JAVA_OPTS} com.sterlingcommerce.woodstock.noapp.NoAppLoader -class com.yantra.integration.adapter.IntegrationAdapter -f Foundation/properties/AGENTDynamicclasspath.cfg -invokeargs "$@"

So you can pass Minheap Maxheap Maxpermsixe like below in startIntegrationServer.sh and start the servers:

${JAVA} **$MINHEAP $MAXHEAP $MAXPERMSIZE** -classpath Foundation/jar/bootstrapper.jar ${AGENT_JAVA_OPTS} com.sterlingcommerce.woodstock.noapp.NoAppLoader -class com.yantra.integration.adapter.IntegrationAdapter -f Foundation/properties/AGENTDynamicclasspath.cfg -invokeargs "$@"
