Reset CA RCM Cache Limits

To support large CA RCM configurations, you can expand CA RCM cache memory limits.

CA RCM cache memory is defined by the number of CA RCM elements (user, resource, role, or link records) that can be held in the cache at once. When the cache is full, elements are swapped in and out of memory - which can affect performance. The default setting limits the memory cache to 500,000 elements.

This procedure describes how to reset cache settings for an existing CA RCM server implementation. In WebSphere/AIX implementations, you can modify these settings before implementation by editing the .ear file you use to install CA RCM server. This saves you from changing settings on each server computer.

To reset CA RCM cache limits

1. Edit the ehcache-sageDal.xml file on the CA RCM server:
   • In standalone JBoss implementations, this file is located in the following directory:

     RCM_install\Server\eurekify-jboss\server\eurekify\deploy\eurekify.war\WEB-INF\classes\
     

     Note: RCM_install is the CA RCM installation directory.

   • In clustered JBoss implementations, this file is located in the following directory:

     C:\jboss4.2.2.GA\server\all\farm\eurekfiy.war\WEB-INF\classes\
     

   • In WebSphere/AIX implementations, this file is located in the eurekify.ear file CA RCM uses for installation, which is located in the following directory:

     \eurekify.war\WEB-INF\classes
     

     After installation, this file is located in the deployed application directory of each server under the following directory:

     /RCM_intall/eurekify.war/WEB-INF/classes
     

2. In the defaultCache element, change the following attribute:

   maxElementsInMemory

   Defines the maximum number of user, resource, role, or link elements stored in cache memory.
