As one of the major features of the IBM WebSphere Application Server v5.0.x, WBI Monitor supports clustering deployment using the WebSphere 5.0.x Application Server and Deployment Manager.
A Cluster is a set of application servers that are managed together and participate in workload management. The servers that are members of a cluster can be on different host machines, as opposed to the servers that are part of the same node and must be located on the same host machine.
Servers that belong to a cluster are members of that cluster set and must all have identical application components deployed on them. Please refer to the WebSphere Application Server and Deployment Manager v5.0.x documentation for details about creating and configuring clusters.
In order to install and deploy the WBI Monitor in a cluster, there are two possible cases:
If you already have an existing cluster that is configured and its members have running web applications, then you must install and deploy the WBI Monitor on each member in that cluster using the manual deployment steps (not the WBI Monitor Installation Wizard). Notice that each node must point to the same database(s).
If you are building a new cluster or adding a new node to a cluster on which the WBI Monitor is installed and deployed, then you should install and deploy the WBI Monitor on each cluster member, either automatically using the WBI Monitor Installation Wizard or manually by performing the manual deployment steps. Notice that each node must point to the same database(s). This must be done before adding each machine to the cluster.
Please refer to Appendix B of this guide: Manual Deployment of WBI Monitor on WebSphere 5.0 for a description of the manual deployment of Monitor Server on WebSphere 5.0
