Set up a cluster on Windows

Clusters enable you to scale the IBM 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.

Prerequisites

Late breaking installation limitations and issues

The multiple servers configuration reduces single points of failure, but requires more hardware, such as additional servers. The multiple profiles configuration also reduces single points of failure; it requires less additional hardware than the multiple servers configuration but you may still need more hardware such as additional memory. The dmgr manages a cell for horizontal cluster nodes.

To conserve hardware, we can also set up vertical cluster members on a single node. Typically, large portal clusters include both horizontal and vertical scaling;

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

1. Prepare the Windows operating system in a clustered environment
2. Prepare the primary node
3. Create and augment a new dmgr profile
4. Prepare to create the cluster
5. Prepare a remote Web server when portal is installed in a clustered environment
6. Configure WebSphere Portal to use a user registry in a clustered environment
7. Prepare additional cluster members
8. Windows cluster: Tune the servers
9. Configure search in a cluster
10. Set up multiple clusters
11. Share database domains between clusters
