(JBoss) Resize the Java Virtual Machine Memory Heap

To support large configurations, you can expand the Java virtual machine (JVM) memory cache for the CA GovernanceMinder server.

Follow these steps:

1. Navigate to the following folders on the CA GovernanceMinder server:

   jboss_install\bin
   

2. Open the run.bat file for editing, and locate the following line:

   set JAVA_OPTS=%JAVA_OPTS% -Xms728m -Xmx1536m -XX:MaxPermSize=256m
   

3. To define the JVM memory heap settings, change the following parameters:

   -Xms

   Defines the minimum size of heap memory. For example, -Xms1200m sets minimum heap memory to 1.2GB. This memory is assigned at server start.

   Note: When using a 64bit JDK, and the available memory is greater than 1400M, set the -Xms parameter to use all available memory.

   -Xmx

   Defines the maximum size of heap memory. For example, -Xmx20g sets maximum heap memory to 20GB. This memory is assigned as needed.

   We recommend, for a 64bit system, that you allocate approximately 3GB of cache memory (RAM) for every 1,000,000 elements allowed in cache memory (3 * maxElementsInMemory).

4. Repeat this procedure on each server in the cluster.
5. Save and close the run.bat file.

   The Java virtual machine memory heap has been resized.
