Increasing the Java Heap Size on a Performance Manager Server

Increase the Java heap size on a Performance Manager server when you receive out-of-memory errors.

To increase the Java heap size on a front-end or application server:

  1. Stop all Performance Manager services.
  2. Click Start > Run.
  3. In the Run dialog box, type regedit into the Open field.
  4. Click OK. The Registry Editor opens.
  5. In the menu tree, choose one of the following locations, depending on your operating system and the server type:
    Performance Manager server Location
    Front-end server HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Apache Software Foundation\Procrun 2.0\SPMFrontendServer195\Parameters\Java
    Application server HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Apache Software Foundation\Procrun 2.0\SPMAppServer195\Parameters\Java
    Chart server HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Apache Software Foundation\Procrun 2.0\SPMChartServer195\Parameters\Java
  6. Double-click JvmMx. The Edit DWORD Value dialog box opens.
  7. In the Base section of the dialog box, click the Decimal option button.
  8. In the Value data field, type the new memory size, for example 1024.
    Note: The value of the Java heap size cannot exceed the available physical RAM on the front-end server machine and enough memory should be left available for other necessary processes. For example, if 2 GB of RAM are available, you can increase the Java heap size to a value of 1.5 GB, which corresponds to a value of 1536 in the Value data field, depending on what other processes are running. If you enter a value that is too big, the server may not start anymore.
  9. Click OK.
  10. Restart all Performance Manager services.
