Increasing memory available to the JVM for IBM Sametime 8.5.2 Media Manager

About this task

If your enterprise has a large number of users (for example if you anticipate up to or more than 10,000 Domino users, or a BHCC of 12,000), it is likely that the Java Virtual Machine (JVM) will consume more memory than it has available. To avoid this condition, set the maximum memory for the JVM at 1.5 GB (1536M) on the IBM Lotus Sametime Media Manager. Use this procedure to set the memory for the JVM.

Procedure

  1. Access the Media Manager System Console.
  2. From a browser, enter the following URL to access the Media Manager System Console. (Do not confuse the Media Manager System Console with the Sametime System Console.)

    http://serverhostname.domain:8800/ibm/console

    where serverhostname.domain is the fully qualified domain name of the Lotus Sametime System Console server.

  3. Enter the WebSphere Application Server User ID and password that you created when you installed the Media Manager.
  4. In the System Console navigation tree, click Server > Server Types > WebSphere application server > STMediaServer.
  5. On the right-side menu under Server Infrastructure, select Java and Process Management > Process Definition.
  6. Under the Additional Properties menu list, select Java Virtual Machine.
  7. On the Java Virtual Machine page under the Configuration tab, set the following parameters:
    • Initial heap size = 256

    • Maximum heap size = 1536

  8. Click the OK button and then Save directly to the master configuration.
  9. Restart the Media Manager for the changes to take effect.
