Sun Java System Reference Configuration Series: Portal Service on Application Server Cluster

ProcedureTo Tune Application Server Instances for Access Manager

Tuning the Application Server instances that host Access Manager is performed by using the amtune utility. For additional information about amtune, see Part I, Basic Performance Tuning, in Sun Java System Access Manager 7.1 Performance Tuning and Troubleshooting Guide.

Perform the following procedure on both am1 and am2..

  1. Change to the following directory:

    # cd /opt/SUNWam/bin/amtune

  2. Open the amtune-env file in a text editor.

  3. Confirm, or if necessary, modify the following values and save the changes.


    Note –

    In a Solaris zones deployment, also set AMTUNE_TUNE_OS=false.

  4. Run the amtune utility.

    # ./amtune directory-manager-password app-server-admin-password

    The utility proposes changes to optimize Access Manager performance.

  5. Review any suggested changes.

    If no undesired changes are proposed, continue to the next step.

  6. Modify the amtune-env file with the following value and save the change.

  7. Repeat Step 4.

    The utility runs a second time, but makes all the changes proposed in Step 4.

  8. Restart the computer.

    Restarting the computer will affect changes to the operating system.

  9. Start the Access Manager instance.

    # /opt/SUNWappserver/appserver/bin/asadmin start-domain --user admin domain1

    When prompted, type the app-server-admin-password.
