Disabling components 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 disable the name server component of a configured server. You can modify this example to disable a different component.

1. Identify the server component and assign it to the nameServer variable.

   • Using Jacl:

     set nameServer [$AdminConfig list NameServer $server]

   • Using Jython:

     nameServer = AdminConfig.list('NameServer', server)
     print nameServer

   Example output:

   (cells/mycell/nodes/mynode/servers/server1|server.xml#NameServer_1)

2. List the components belonging to the server and assign them to the components variable.

   • Using Jacl:

     set components [$AdminConfig list Component $server]

   • Using Jython:

     components = AdminConfig.list('Component', server)
     print components

   The components variable contains a list of components. Example output:

   (cells/mycell/nodes/mynode/servers/server1|server.xml#ApplicationServer_1)
   (cells/mycell/nodes/mynode/servers/server1|server.xml#EJBContainer_1)
   (cells/mycell/nodes/mynode/servers/server1|server.xml#NameServer_1)
   (cells/mycell/nodes/mynode/servers/server1|server.xml#WebContainer_1)

3. Identify the name server component and assign it to the nameServer variable.

   Since the name server component is the third element in the list, retrieve this element by using index 2.

   • Using Jacl:

     set nameServer [lindex $components 2]

   • Using Jython:

     # get line separator 
     import  java lineSeparator = java.lang.System.getProperty('line.separator')
     arrayComponents = components.split(lineSeparator)
     nameServer = arrayComponents[2]
     print nameServer

   Example output:

   (cells/mycell/nodes/mynode/servers/server1|server.xml#NameServer_1)

4. Disable the name server component by changing the nested initialState attribute belonging to the stateManagement attribute. For example:

   • Using Jacl:

     $AdminConfig modify $nameServer {{stateManagement {{initialState STOP}}}}

   • Using Jython:

     AdminConfig.modify(nameServer, [['stateManagement', [['initialState', 'STOP']]]])

5. Save the configuration changes. See the Saving configuration changes with the wsadmin tool article for more information.

6. In a network deployment environment only, synchronize the node. See the Synchronizing nodes with the wsadmin tool article for more information.
