Edit JVM Memory Options

If the Java process runs out of memory, you can increase the memory available to it.

On Windows, Follow these steps:

You need to edit the JVM memory options JvmMs, JvmMx, JvmSs and Classpath. To do this, use the service update command or edit the following registry key on Windows:

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\ComputerAssociates\Identity Manager\Procrun 2.0\im_jcs

Note: You can use Apache procrun arguments to update the service parameters. For more information, see Procrun service application at http://jakarta.apache.org

On UNIX, Follow these steps:

Create a file named jvm_options.conf in the data folder with the following Java arguments:

-Xms128M -Xmx1024M -d64 

-Xms

Specifies the minimum heap memory allowed for CA IAM CS

Example: -Xms128M specifies that the minimum heap memory allowed for CA IAM CS is 128 MB.

-Xmx

Specifies the maximum heap memory allowed for CA IAM CS.

Example: -Xmx1024M specifies that the maximum heap memory allowed for CA IAM CS is 1024 MB.

-d64

Specifies that the JVM is run in a 64-bit environment.

Note: For more information, see the documentation for the Java command tool at www.oracle.com.
