For information on the installation procedure, see the Sun Java System Application Server Installation Guide (if using the stand-alone Application Server) or the Sun Java Enterprise System Installation Guide (if using Java Enterprise System).
Configure the web server. For more information, see Sun Java System Application Server 9.1 High Availability Administration Guide.
Create Application Server clusters or server instances to participate in load balancing.
Deploy applications to these clusters or instances.
