As one of the major features of the IBM WebSphere Application Server v5 and v6, BI Monitor supports clustering deployment using the WebSphere 5 and 6 Application Server and Deployment Manager.
A Cluster is a set of application servers that are managed together for the purpose of failover handling 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 documentation for details about creating and configuring clusters.
In order to install and deploy the BI 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 WebSphere BI Monitor must be installed and deployed on the first member in that cluster using the manual deployment steps (not the BI Monitor Installation Wizard). Notice that each node must point to the same database(s).
If you are building a new cluster, then WebSphere BI Monitor should be installed and deployed on the first member of the cluster either automatically or manually. Notice that each node must point to the same database(s).This must be done before creating the cluster.
Please refer to Appendix B of this guide: Manual Deployment of BI Monitor on WebSphere 5 for a description of the manual deployment of Monitor Server on WebSphere 5.
