EPM 11.1.2 - How-to increase Essbase CSS Java heap size

Increase the Java heap size only when during peak periods with a large number of concurrent logins, Essbase agent run out of memory / terminate abnormally / hangs.


Tip: How-to increase Java heap size:

o Stop Essbase Server.

Since OPMN is used to start Essbase, you need to go to MIDDLEWARE_HOME\user_projects/epmsystem1\user_projects\epmsystem1\config\OPMN\opmn, and set or update below two minimum and maximum heaps parameters in opmn.xml file under tag <process-type id="EssbaseAgent" module-id="ESS">  <environment>

   <variable id="ESS_CSS_JVM_OPTION4" value="-Xms256M"/>

   <variable id="ESS_CSS_JVM_OPTION5" value="-Xmx1024M"/>


If ESS_CSS_JVM_OPTION4 and ESS_CSS_JVM_OPTION5 is already in use, set this value for the next available ESS_CSS_JVM_OPTION. For example: ESS_CSS_JVM_OPTION9.


Tip: If you are not using OPMN to start Essbase and use startup script i.e. startEssbase.bat | .sh then you need to set above parameters (ESS_CSS_JVM_OPTION) in setEssbaseEnv.bat | .sh file.


o Start Essbase Server.
