Configure the message listener service using scripting

Use scripting to configure the message listener service.

Configure the message listener service for an application server:

In the following examples, code blocks beginning with wsadmin> show code that is entered by the user. Lines that do not begin with wsadmin> show code that has been returned by the console.

Tasks

1. Identify the application server and assign it a variable. For this example the variable is named server.

   • Use Jacl:

     wsadmin>set server [$AdminConfig getid /Cell:mycell/Node:mynode/Server:server1/]
     

   • Use Jython:

     wsadmin>server = AdminConfig.getid("/Server:server1/")
     wsadmin>print server
     

   Example output:

   server1(cells/mycell/nodes/mynode/servers/server1|server.xml#Server_1183122130078)
   

2. Idenify the message listener service for the server and assign it to a variable. In this example the variable is named mls.

   • Use Jacl:

     wsadmin>set mls [$AdminConfig list MessageListenerService $server]
     

   • Use Jython:

     wsadmin>mls = AdminConfig.list('MessageListenerService', server)
     wsadmin>print mls
     

   Example output:

   (cells/mycell/nodes/mynode/servers/server1|server.xml#MessageListenerService_1183122130078)
   

3. Modify various attributes with one of the following examples:
   • This example command changes the attributes of the thread pool for the message listener service:

     • Use Jacl:

       wsadmin>$AdminConfig modify $mls {{threadPool {{inactivityTimeout 4000} 
       {isGrowable true} {maximumSize 100} {minimumSize 25}}}}
       

     • Use Jython:

       wsadmin>AdminConfig.modify(mls, [['threadPool', [['inactivityTimeout', 4000], 
       ['isGrowable',  'true'], ['maximumSize', 100], ['minimumSize', 25]]]])
       

   • Create a listener port using the server and mls variables to provide information about the server and the message listener service:

     • Use Jacl:

       wsadmin>set new [$AdminConfig create ListenerPort $mls {{name my} 
       {destinationJNDIName di} {connectionFactoryJNDIName jndi/fs}}]
       wsadmin>$AdminConfig create StateManageable $new {{initialState START}}
       

     • Use Jython:

       wsadmin>new = AdminConfig.create('ListenerPort',mls,[['name','myLP']
       ,['destinationJNDIName','jms/myqueue'],['connectionFactoryJNDIName','jms/myCF']])
       wsadmin>print new
       

     Example output:

     myLP(cells/mycell/nodes/mynode/servers/server1|server.xml#ListenerPort_1318513831827)
     

   • Assign a variable to the 'State Manageable' property on the listener port and use it to change the initialState property on the listener port. In this example the variable is named sm.

     • Use Jython:

       wsadmin>sm = AdminConfig.list('StateManageable',new)
       wsadmin>print sm
       

     • Example output:

       (cells/mycell/nodes/mynode/servers/server1|server.xml#StateManageable_1318513831827)
       

     • Use Jython:

       wsadmin>AdminConfig.modify(sm,[['initialState','START']])
       

   • Modify a property on the first listener port on the message listener service, using jython.
     • Return a list of the listener ports on the message listener service:

       wsadmin>lports = AdminConfig.showAttribute(mls,'listenerPorts')
       wsadmin>print lports
       

       A list of the listener ports on the message listener service is returned in a string:

       myLP(cells/mycell/nodes/mynode/servers/server1|server.xml#ListenerPort_1318504021702) 
       myLP1(cells/mycell/nodes/mynode/servers/server1|server.xml#ListenerPort_1318504495
       733) myLP2(cells/mycell/nodes/mynode/servers/server1|server.xml#ListenerPort_1318513831827)]
       

     • Remove the first and last character of each listener port in the list string, so that wsadmin can use the returned information:

       wsadmin>clp = lports[1:len(lports)-1]
       wsadmin>print clp
       

       The result is returned:

       myLP(cells/mycell/nodes/mynode/servers/server1|server.xml#ListenerPort_1318504021702) 
       myLP1(cells/mycell/nodes/mynode/servers/server1|server.xml#ListenerPort_13185044957
       33) myLP2(cells/mycell/nodes/mynode/servers/server1|server.xml#ListenerPort_1318513831827)
       

     • Select the first listener port in the list:

       wsadmin>lport =clp.split(" ")[0]
       wsadmin>print lport
       

       Result:

       myLP(cells/mycell/nodes/mynode/servers/server1|server.xml#ListenerPort_1318504021702)
       

     • Alter a property on the listener port. In this example the maxRetries property has been altered:

       wsadmin>AdminConfig.modify(lport, [['maxRetries', 2]])
       

   • Modify a property on the first listener port on the message listener service, using jacl:

     wsadmin>set lports [$AdminConfig showAttribute $mls listenerPorts]
     wsadmin>set lport [lindex $lports 0]
     wsadmin>$AdminConfig modify $lport {{maxRetries 2}}
     

4. Save the configuration changes.
5. In a network deployment environment only, synchronize the node.
