The Java process that generates reports on the server ranĀ out of java heap memory most likely reason is theĀ volume of the report's data retrieved.


By default, the server allocates 512 MB to the Java process that generates reports on the server. If you get a Java heap space or out of memory error in the console while running a report, allocate more memory to the report process. For example, you can increase the maximum memory available for generating reports to 1024 MB.

Follow these steps:

Connect to the server as an administrator using CA WA Desktop Client.

  1. Open the Admin perspective.
  2. Right-click Topology in the Admin view, and select Open from the pop-up menu.
    The Topology view opens.
  3. Right-click the server connection name in the Topology view, and select Configure Shared Parameters from the pop-up menu.
    The Server Shared Parameters view opens.
  4. Select the Internal tab.
    The Internal tab opens.
  5. Click the Show Advanced Parameters icon.
