Why and when to perform this task
You can manage application servers collectively using a cluster. Use the Server Cluster page to view and manage the cluster.Note: If you plan to create a cluster of servers that will span multiple systems in a sysplex and will have stateful session beans with an activation policy of Transaction deployed in them, the passivation directory should reside on an HFS (hierarchical file system) that is shared across the multiple systems in the sysplex on which the clustered servers will be running. For more information, see Considerations for clustered servers and stateful session beans.
Steps for this task
To create an empty cluster, do not include an existing server in this cluster.
To create a cluster based on an existing server, choose Select an existing server to add to this cluster and select the server you want to add. The server you add becomes a template for any additional cluster members that you add to the cluster. Be sure that the template is configured correctly before adding more cluster members that are based on this template.
Note: On z/OS, defining virtual hosts is optional.

What to do next
If you have made changes to plug-ins, transports, or virtual hosts you must regenerate the plug-in configuration. See Regenerating Web server plug-in configurations for more information. For more information about setting up clustering, see Balancing workloads with clusters.
