Set up multiple clusters on Windows
Overview
The majority of the steps to build another cluster are the same as when building the first cluster in the same cell, with a few exceptions. Basically, the new profile will be designated as the primary profile, using IBM WebSphere Portal clustering terminology, and will then be used as the basis for the new cluster definition. This duplicates the build process of the first cluster in the cell. During the federation process, if any applications on this new node already exist in the cell (because they are in use by the first cluster), then dmgr will not allow them to be added. After federation, the applications that already exist in the cell are not mapped to the WebSphere_Portal server on the newly federated node, and thus the existing applications must be remapped to this newly federated server to restore its application list. Therefore, depending on the configuration of the new profile, there will likely be some combination of applications shared with the other existing cluster, and some applications unique to this new profile.
Prerequisites
- Prepare the Windows operating system in a clustered environment
- Prepare the primary node on Windows
- Create and augment a new dmgr profile on Windows
- Windows cluster: Tune the servers
