Configuring an HTTP Server to load balance multiple Tivoli Enterprise Portal Servers

You can install and configure an HTTP Server to load balance multiple Tivoli Enterprise Portal Servers.

1. Complete the steps described in the Setting up load balancing for a high availability dashboard environment roadmap that occur before the step for configuring the load balancing HTTP server.
2. Install and configure an HTTP server.

   The IBM HTTP Server can be installed using a Jazz™ for Service Management image that is provided with IBM® Tivoli Monitoring. See the "Download instructions" in the IBM Tivoli Monitoring Information Center for information on the WebSphere Application Server Supplement images that contain the IBM HTTP Server. For instructions on installing the IBM HTTP Server Version 8.5, see IBM HTTP Server Version 8.5 Information Center. The IBM HTTP Server Information Center also provides information on how to download and install the IBM HTTP Server from an external IBM Installation Manager repository.

   Note: The HTTP Server Plug-in for IBM WebSphere Application Server must be installed into the HTTP server. The plug-in is provided with the IBM HTTP Server. However, if you are using a different HTTP Server, the plug-in is included on a Jazz for Service Management image that is provided with IBM Tivoli Monitoring. See the "Download instructions" in the IBM Tivoli Monitoring Information Center for information on the WebSphere Application Server Supplement images that contain the HTTP Server Plug-in for IBM WebSphere Application Server.

3. Assign a unique clone ID to each Tivoli Enterprise Portal Server. For more information, see Setting Clone IDs on each Tivoli Enterprise Portal Server.
4. Generate the plugin-cfg.xml file for each Tivoli Enterprise Portal Server and configure the HTTP server to use the plugin details. For more information, see Generating the plugin-cfg.xml file.
