Creating clusters using scripting

Before starting this task, the wsadmin tool must be running. See the Starting the wsadmin scripting client article for more information.

Perform the following steps to create a cluster:

1. Identify the server to convert to a cluster and assign it to the server variable:

   Using Jacl:

   set server [$AdminConfig getid /Cell:mycell/Node:mynode/Server:server1/]
   

   Using Jython:

   server = AdminConfig.getid('/Cell:mycell/Node:mynode/Server:server1/')

2. Convert the existing server to a cluster by using the convertToCluster command passing in the existing server and the cluster name:

   Using Jacl:

   $AdminConfig convertToCluster $server myCluster1

   This command converts a cluster named myCluster with server1 as its member. Using Jython:

   print AdminConfig.convertToCluster(server, 'myCluster1')

   Example output:

   myCluster1(cells/mycell/cluster/myCluster1|cluster.xml#ClusterMember_1)

3. Save the configuration changes. See the Saving configuration changes with the wsadmin tool article for more information.

4. In a network deployment environment only, synchronize the node. See the Synchronizing nodes with the wsadmin tool article for more information.
