AMTUNE
By default, amtune is configured to run in REVIEW mode. IN this mode, amtune will suggest tuning recommendations but will not make any changes to the deployment. This is a safe mode of running. This and other parameters are defined in a file called /opt/SUNWam/bin/amtune/amtune-env. The amtune script is a useful starting point to define the correct tuning parameters for the portal.
To invoke amtune, use the following command:
amtune directory-server-admin-password web-server-admin-password
The following is displayed:
