Promoting a server that has Business Process Choreographer configured to a cluster

This describes how to promote a server that runs applications that contain business processes or human tasks or both to a cluster.

Why and when to perform this task

You have one or more applications, which contain business processes or human tasks, running on a standalone server in an ND cell, and you want to create a cluster from this server. For example, to increase the workload capacity, availability, or to consolidate multiple applications that have their own profiles.

Steps for this task

  1. Create the cluster. Perform Creating a cluster, using the existing server that has Business Process Choreographer configured on it.
    Restriction:
    • If you have an existing server that has Business Process Choreographer configured on it, it must be the first server in the cluster.
    • If you want to create the cluster using one of the templates provided, use the defaultProcessServertemplate.
  2. Activate the changes. If the server is not running start it. If the server is running, stop and start it.

Result

Your applications are now running on the same server, but the server is now a member of the cluster, and the resources have cluster scope.

What to do next

You can add more members to the cluster to share the workload and increase availability.
