IBM WebSphere - Convert a static cluster into a dynamic cluster

This assumes you have already created a static cluster.

  1. In the WebSphere admin console, expand Servers > Clusters, and select Dynamic clusters.
  2. Select New.
  3. At Step 1, select WebSphere application server and select Next.
  4. At Step 2, select Automatically define new cluster members with rule or Manually define cluster members and select Next.
  5. At Step 3, if you selected Manually define cluster members, select an existing static cluster and select Next.
  6. At Step 5, select your preferred properties, and select Next.
  7. Select Finish.
  8. Select Save.

The cluster will no longer be listed at Servers > Clusters > WebSphere application server clusters, and will instead be listed at Servers > Clusters > Dynamic clusters.

At Servers > Server types > WebSphere application servers, the servers in the cluster will be listed. In this example, server01 is not part of a cluster, and server03 and server04 are members of cluster1. This view also can be used to know if the JVMs are in a vertical or horizontal cluster. In this example, server03 and server04 are in a horizontal cluster, as the servers are on different servers (was1 / was2).

 

Servers > Clusters > Dynamic clusters > cluster_name > Dynamic cluster members will display the cluster members.
