Disabling components using scripting

 

You can disable components with scripting and the wsadmin tool. 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 disable the name server component of a configured server. You can modify this example to disable a different component.

 

Procedure

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

   Use Jacl:

   set nameServer [$AdminConfig list NameServer $server]
   

   • Use 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.

   Use Jacl:

   set components [$AdminConfig list Component $server]
   

   • Use 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.

   Use Jacl:

   set nameServer [lindex $components 2]
   

   • Use 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:

   Use Jacl:

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

   • Use 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.
