### Prerequisites for Setting Up Load Balancing

Before configuring your load balancer, you must:

- Install a web server.

- Install the load balancer plug-in.

  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.
