PingAccess

Modifying the Java heap size

Modify the Java heap size for both Windows and Linux installations, including the Windows and Linux services.

Steps

  1. Edit the jvm-memory.options file located in the PA_HOME/conf directory.

  2. Specify overall heap size by modifying the #Minimum heap size and #Maximum heap size parameters.

    Choose from:

    • Modify -Xms512m to change the #Minimum heap size value.

    • Modify -Xmx512m to change the #Maximum heap size value.

    Specify units as m, megabytes, or g, gigabytes.

  3. Specify young generation size by modifying the #Minimum size for the Young Gen space and #Maximum size for the Young Gen space variables.

    Choose from:

    • Modify -XX:NewSize=256m to change the #Minimum size for the Young Gen space value.

    • Modify -XX:MaxNewSize=256m to change the #Maximum size for the Young Gen space value.

      Set values to 50% of #Minimum heap size and #Maximum heap size.

    Not advisable if selecting the G1 collector. For more information, see Garbage Collector Configuration.

  4. If you are running PingAccess as a Windows service, run the generate-wrapper-jvm-options.bat file located in the PA_HOME/sbin/windows directory.

    This file applies the changes from the jvm-memory.options file to the wrapper-jvm-options.conf file, which is used by the Windows service.
