Querying cluster state using scripting

 

You can query cluster states using the wsadmin tool and scripting. 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 query cluster state:

 

Procedure

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

   • Use Jacl:

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

   • Use 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.

   • Use Jacl:

     $AdminControl getAttribute $cluster state
     

   • Use Jython:

     AdminControl.getAttribute(cluster, 'state')
     

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