How to change CA APM Environment Performance Agent (EPAgent) heap size.



If not changed, EPAgent uses the Java default heap memory settings.

Modify the EPACtrl Script file to set these values. 

  • Edit the EPACtrl script file.
  • Add the minimum (-Xms) and maximum (-Xmx) arguments within EpaCmd.

In the example below, the minimum value is set to 256 MB and the maximum value to 1024 MB. 

EpaCmd="java -cp lib/EPAgent.jar:lib/IntroscopeServices.jar:lib/Agent.jar:epaplugins/epaMQMonitor/epaMQMonitor.jar:epaplugins/epaMQMonitor:epaplugins/epaMQMonitor/lib/ -Xms256m -Xmx1024m com.wily.introscope.api.IntroscopeEPAgent" 

  • Save the EPACtrl script file.
  • Restart the EPAgent.
