Querying cluster state 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 query cluster state:

1. Identify the Cluster MBean and assign it to the cluster variable.

   • Using Jacl:

     set cluster [$AdminControl completeObjectName cell=mycell,type=Cluster,name=cluster1,*

   • Using Jython:

     cluster = AdminControl.completeObjectName('cell=mycell,type=Cluster,name=cluster1,*')
     print cluster

   This command returns the Cluster MBean.Example output:

   WebSphere:cell=mycell,name=cluster1,mbeanIdentifier=Cluster,type=Cluster,process=cluster1

2. Query the cluster state.

   • Using Jacl:

     $AdminControl getAttribute $cluster state

   • Using Jython:

     AdminControl.getAttribute(cluster, 'state')

   This command returns the value of the run-time state attribute.
