(WebSphere) Resize the Java Virtual Machine Memory Heap

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

Follow these steps:

1. In the WebSphere Administrative Console, click Servers, Application Servers, and select a server in the cluster.
2. Click Process Definitions, Java Virtual Machine.
3. To define JVM memory heap settings, change the following fields:

   Initial Heap

   Defines the memory reserved for CA Identity Governance upon startup, in megabytes.

   Maximum Heap

   Defines the maximum memory that CA Identity Governance can use, in megabytes.

   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 for each server in the cluster.
