Example: Migrating - Creating a server group

In WebSphere Application Server V6.x, ServerClusters have replaced V4.0 ServerGroups. The members of a cluster are servers with identical application configurations. The following examples demonstrate how to create a server group in WebSphere Application Server V4.0 and V6.x. They assume that an application server named as1 already exists and is used as the first clone in a server group:

• wscp V4.0

  ServerGroup create /ServerGroup:sg1/ -baseInstance /Node:mynode/ApplicationServer:as1/
  -serverGroupAttrs {{EJBServerAttributes {{SelectionPolicy roundrobin}}}}

• wsadmin V6.x Using Jacl:

  set serverid [$AdminConfig getid /Node:mynode/Server:as1/]
  $AdminConfig convertToCluster $serverid MyCluster
  $AdminConfig save

  Using Jython:

  serverid = AdminConfig.getid('/Node:mynode/Server:as1/')
  AdminConfig.convertToCluster(serverid, 'MyCluster')
  AdminConfig.save()
