ProcedureTo Tune a Web Container for a Distributed Authentication UI Server

Before You Begin

Install and configure the Distributed Authentication UI server on the web container.

  1. Edit the parameters in the amtune-env configuration file to specify the web container and tuning options.

    To run the script in review mode, set the AMTUNE_MODE variable to REVIEW in the amtune-env file.

  2. Run the amtune script in review mode, which calls the appropriate web container script based on values in the amtune-env file.

    In review mode, the amtune script suggests tuning recommendations but does not make any changes to the deployment.

  3. Review the tuning recommendations in the debug log file. If needed, make changes to the amtune-env file based on this run.

  4. To make tuning changes, set the AMTUNE_MODE variable to CHANGE in the amtune-env file.

  5. Run the amtune script in change mode to make the tuning changes to the deployment.
