Create clusters using scripting

 

You can create clusters using scripting and the wsadmin tool. Before starting this task, the wsadmin tool must be running. See the Start the wsadmin scripting client article for more information.

 

Overview

Perform the following steps to create a cluster:

 

Procedure

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

   Use Jacl:

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

   Use 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:

   Use 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.
