Increasing the JVM setting to optimize ClearQuest Web server performance

After installing or upgrading the ClearQuest Web server, increase the JVM setting to improve performance and prevent stability issues such as out-of-memory errors.

Before you begin

This procedure shows how to run the WebSphere commands to increase the JVM setting. The examples assume that ClearQuest Web server is deployed in the default profile cqwebprofile. If your ClearQuest Web server is deployed in a profile with a different name, replace cqwebprofile with the name of the profile used in your environment.

About this task

This procedure provides instructions for running WebSphere commands on Windows and UNIX or Linux systems.

Procedure

To increase the JVM setting on Windows systems:

  1. Open the command window or shell and go to the WebSphere Application Server bin directory.
    • Windows:
      wsadmin.bat -profile -profileName cqwebprofile "C:\Program Files\IBM\RationalSDLC\ClearQuest\cqweb\scripts\teamAdminUtils.jacl" -c "setJvmMaxHeapSize 1024"
    • UNIX or Linux:
      ./wsadmin.sh -profile -profileName cqwebprofile "/opt/ibm/RationalSDLC/clearquest/cqweb/scripts/teamAdminUtils.jacl" -c "setJvmMaxHeapSize 1024"
  2. Run the following WebSphere command to set the JVM heap size for the WebSphere Application Server profile in which ClearQuest Web server is deployed 1024.
    • Windows:
      wsadmin.bat -profile -profileName cqwebprofile "C:\Program Files\IBM\RationalSDLC\ClearQuest\cqweb\scripts\teamAdminUtils.jacl" -c "setJvmMaxHeapSize 1024"
    • UNIX or Linux:
      ./wsadmin.sh -profile -profileName cqwebprofile "/opt/ibm/RationalSDLC/clearquest/cqweb/scripts/teamAdminUtils.jacl" -c "setJvmMaxHeapSize 1024"
  3. Restart the WebSphere Application Server profile for the change to take effect.
    • Windows:
      stopServer.bat server1 -profileName cqwebprofile
      startServer.bat server1 -profileName cqwebprofile
    • UNIX or Linux:
      ./stopServer.sh server1 -profileName cqwebprofile
      ./startServer.sh server1 -profileName cqwebprofile
