About this task

Perform the following steps to query cluster state:

Procedure

  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.
