Increasing JVM Memory Settings

Depending on the size of your environment, you might need to increase the JVM memory settings (heap size) for your Web application server to optimize performance. While the default can be used in a test environment (single-server-type configuration), the heap size must be increased for use in a production environment (multiple servers).

You can modify the JVM memory settings, depending on whether Profitability and Cost Management is being launched through a Windows service or from the command line. In either case, for 32-bit systems, Oracle recommends a maximum setting of 1024 MB. You can change the custom startup scripts.

For additional information on JVM memory settings, see the Oracle Hyperion Enterprise Performance Management System Installation and Configuration Guide.

  To increase the JVM memory allocation if Profitability and Cost Management is being launched from Windows service:

  1. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Hyperion Solutions\Product Component\ServiceName.

  2. Using regedit, update the Windows registry for Windows services to set the JVMOptionX (where X is 1, 2, and so on) whose value starts with -Xmx. For 32-bit systems, Oracle recommends a maximum setting of 1024 MB.

  3. Restart the Windows service for the product.

  To increase the JVM memory allocation if Profitability and Cost Management is being launched from the command line:

  1. Edit your start script to specify the desired heap size. For 32-bit systems, Oracle recommends a maximum setting of 1024 MB.

  2. Restart the script for the product.
