Resize the Java Virtual Machine Memory Heap in a JBoss/Windows Environment

To support large CA RCM configurations, you can expand the Java Virtual Machine (JVM) memory cache for CA RCM server.

To resize the Java Virtual Machine memory heap in a JBoss/Windows Environment

1. Browse to one of the following folders on the CA RCM server:
   • In a standalone JBoss implementation:

     RCM_install\Server\eurekify-jboss\bin\
     

     Note: RCM_install is the CA RCM installation directory.

   • In a clustered JBoss implementation:

     C:\jboss4.2.2.GA\bin
     

2. Open the run.bat file for editing.
3. Find the following line:

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

4. Change the following parameters to define JVM memory heap settings:

   -Xms

   Defines the minimum size of heap memory. For example, -Xms1200m sets minimum heap memory to 1.2 GB.

   -Xmx

   Defines the maximum size of heap memory. For example, -Xmx20g sets maximum heap memory to 20 GB.

5. In a clustered JBoss implementation, repeat this procedure on each server in the CA RCM cluster.
