Create cluster members using scripting

 

Overview

We can also use the AdminTask object to perform this task. For more about using the AdminTask object to create cluster members, see the Commands for AdminTask object article. To create cluster members using the AdminConfig object, perform the following steps:

 

Procedure

1. Start wsadmin

2. Identify the existing cluster and assign it to the cluster variable:

   • Jacl:

     set cluster [$AdminConfig getid /ServerCluster:myCluster1/]
     
     

   • Jython

     cluster = AdminConfig.getid('/ServerCluster:myCluster1/')
     print cluster
     

   Example output

   myCluster1(cells/mycell/cluster/myCluster1|cluster.xml#ServerCluster_1)
   

3. Identify the node to create the new server and assign it to the node variable:

   • Jacl:

     set node [$AdminConfig getid /Node:mynode/]
     
     

   • Jython

     node = AdminConfig.getid('/Node:mynode/')
     print node
     

   Example output:

   mynode(cells/mycell/nodes/mynode|node.xml#Node_1)
   

4. (Optional) Identify the cluster member template and assign it to the serverTemplate variable:

   • Jacl:

     set serverTemplate [$AdminConfig listTemplates Server]
     

   • Jython

     serverTemplate = AdminConfig.listTemplates('Server')
     print serverTemplate
     

   Example output

   server1(templates/default/nodes/servers/server1|server.xml#Server_1)
   

5. Create the new cluster member, by using the createClusterMember command.

   • The following example creates the new cluster member, passing in the existing cluster configuration ID, existing node configuration ID, and the new member attributes:

     • Jacl:

       $AdminConfig createClusterMember $cluster $node {{memberName clusterMember1}}
       

     • Jython

       AdminConfig.createClusterMember(cluster, node, [['memberName', 'clusterMember1']])
       

   • The following example creates the new cluster member with a template, passing in the existing cluster configuration ID, existing node configuration ID, the new member attributes, and the template ID:

     • Jacl:

       $AdminConfig createClusterMember $cluster $node {{memberName clusterMember1}} $serverTemplate
       $AdminConfig save
       

     • Jython

       print AdminConfig.createClusterMember(cluster, node, [['memberName',  'clusterMember1']], serverTemplate)
       

     Example output

     clusterMember1(cells/mycell/clusters/myCluster1|cluster.xml$ClusterMember_2)
     

6. In a network deployment environment only, synchronize the node.
