Adjusting the default heap size for the OpsCenter server service

If the OpsCenter server processes consume a large amount of memory (which may happen with large OpsCenter configurations), it may be helpful to increase the heap size of the OpsCenter Server service.

See About adjusting the heap size or cache size for OpsCenter services.

Note:

The information that is published in this section is based on the tests that were performed in Veritas Lab in a controlled environment with expert users. These can only be used as guidelines and should not be used as 100% accurate benchmarks.

The default heap size of the OpsCenter Server service can be increased from 2048 MB to a higher value (like 4096 MB). You can determine a higher value based on the physical memory (RAM) and the virtual memory that is available on your system.

To adjust the default heap size on Windows

  1. Open the OpsCenterServerService.xml file from the following location on the OpsCenter server:

    INSTALL_PATH\OpsCenter\server\bin

    Note:

    Save a copy of the OpsCenterServerService.xml file before modifying it.

  2. Modify the -Xmx value in the following string:
    <CmdArg value="-Xrs -Xmx2048M

    For example, replace -Xmx2048 with -Xmx4096 to increase the maximum heap size from 2048 MB to 4096 MB.

  3. Save the OpsCenterServerService.xml file.
  4. You must restart OpsCenter server services for the changes to be effective.

    Enter the following commands to first stop and then start all OpsCenter server services as follows:

    INSTALL_PATH\OpsCenter\server\bin\opsadmin.bat stop

    INSTALL_PATH\OpsCenter\server\bin\opsadmin.bat start

To adjust the default heap size on UNIX

  1. Open the startserver file from the following location:

    INSTALL_PATH>/SYMCOpsCenterServer/bin

    Note:

    Save a copy of the startserver file before modifying it.

  2. Modify the -Xmx2048M value in the following string:
    MAX_HEAP=-Xmx2048M

    For example, replace -Xmx2048M with -Xmx4096M to increase the maximum heap size from 2048 MB to 4096 MB.

  3. Save the startserver file.
  4. You must restart all OpsCenter server processes for the changes to be effective.

    Enter the following commands to first stop and then start all OpsCenter server processes as follows:

    INSTALL_PATH/SYMCOpsCenterServer/bin/opsadmin.sh stop

    INSTALL_PATH/SYMCOpsCenterServer/bin/opsadmin.sh start
