Set up a cluster on Windows

Clusters enable you to scale WebSphere Portal configuration. Clusters also enable enterprise applications to be highly available because requests are automatically routed to the running servers in the event of a failure. There are numerous cluster configuration, such as horizontal, vertical, multiple, and dynamic.


Prerequisites

Late breaking installation limitations and issues

The following illustration depicts a horizontal cluster configuration where IBMWebSphere Portal is installed on multiple servers. This configuration reduces single points of failure, but requires more hardware.

To conserve hardware, you can also set up a vertical cluster with multiple portal instances on a single node.

In response to customer requests, the instructions to setup WebSphere Portal has been improved to provide OS specific instructions for setting up a production environment. Select OS to get started.

After completing the installation remember to tune the servers in the portal environment in order to achieve better performance. The Base Portal Tuning scenarios in the WebSphere Portal and Lotus Web Content Management 6.1.x Performance Tuning Guide provides information about tuning the WAS, WebSphere Portal services, databases, directory servers and more. Base Portal Tuning scenarios are the foundation to most performance tuning. In a cluster environment, there are additional steps you should take to tune WAS, the Web server, and more. First review and take the necessary steps provided in the Base Portal Tuning scenarios, then review and take additional necessary steps in the Tuning a Cluster Environment chapter of the tuning guide.
