Learning more about clustering WebSphere Process Server V6.0

Clusters are sets of managed servers that provide high availability and workload balancing for applications. A cluster can be distributed over multiple physical systems and platforms. Clustered servers provide a better capacity and availability to your applications than a single server environment:



  • Workload balancing by running an application on multiple servers that are managed by a cluster. The cluster balances the workload across all servers in the cluster.
  • Extensibility and flexibility are guaranteed by adding more processing power (hardware) to the cluster and configuring new cluster members dynamically.
  • High availability through failover and recovery support. Outages on one server are compensated for by other members in the cluster, which handle the workload and proceed without interruption in service.
  • Maintenance is simplified because you can stop specific cluster members. It is not necessary to stop the application.
