How to create a cluster and servers?

Use wsadminlib methods createCluster() and createServerInCluster().

First create a cluster, specifying the cell name and cluster name:

createServerInCluster( 'cluster1', 'node1', 'server1')
createServerInCluster( 'cluster1', 'node1', 'server2')


That was easy. We created one cluster with two servers. This screenshot shows the two servers with the cluster name in the Admin Console.
