Disable components using scripting

 

Overview

Perform the following steps to disable the name server component of a configured server. We can modify this example to disable a different component.

 

Procedure

1. Start wsadmin

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

   • Jacl:

     set nameServer [$AdminConfig list NameServer $server]
     

   • Jython

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

   Example output:

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

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

   • Jacl:

     set components [$AdminConfig list Component $server]
     

   • 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)
   

4. 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.

   • Jacl:

     set nameServer [lindex $components 2]
     

   • 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)
   

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

   • Jacl:

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

   • Jython

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

6. In a network deployment environment only, synchronize the node.
