Installing CA Performance Center › Installation Considerations › Modify Maximum Memory Usage for Each Service

Modify Maximum Memory Usage for Each Service

Modify the maximum memory usage for the CA Performance Center daemons to enable them to run effectively. For system requirements, see the Release Notes.

You can configure memory allocation during or after the installation.

Follow these steps:

1. Log in to the server where you have installed CA Performance Center.
2. Enter the following command:

   more /proc/meminfo
   

   The total memory usage of each process is displayed.

3. Make a note of the total memory.
4. Modify the maximum memory for a daemon as follows:
   1. Edit the following file:

      /Installation Directory/PerformanceCenter/Service Subdirectory/conf/wrapper.conf
      

      Note: The Service subdirectory is one of the following options:

      • PC (Console daemon)
      • DM (Device Manager daemon)
      • EM (Event Manager daemon)
   2. Search for the parameter 'wrapper.java.maxmemory'.
   3. Change the current value. For example, in a small deployment, set it to '3072' (the units are MB).
   4. Save the file.
   5. Stop and restart each daemon by entering the following commands:

      service service name stop
      

      service service name start
      

      Note: The service name is one of the following options:

      • caperfcenter_console
      • caperfcenter_devicemanager
      • caperfcenter_eventmanager

   The maximum amount of memory is configured for a deployment of your scalability requirements.
