Configure the message listener service using scripting

Use scripting to configure the message listener service. Before starting this task, the wsadmin tool must be running. See the Starting the wsadmin scripting client article for more information.

Overview

Perform the following steps to configure the message listener service for an application server:

Procedure

1. Identify the application server and assign it to the server variable:

   Using Jacl:

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

   • Using Jython:

     server = AdminConfig.getid('/Cell:mycell/Node:mynode/Server:server1/')
     print server

   Example output:

   server1(cells/mycell/nodes/mynode/servers/server1|server.xml#Server_1)

2. Identify the message listener service belonging to the server and assign it to the mls variable:

   Using Jacl:

   set mls [$AdminConfig list MessageListenerService $server]

   • Using Jython:

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

   Example output:

   (cells/mycell/nodes/mynode/servers/server1|server.xml#MessageListenerService_1)

3. Modify various attributes with one of the following examples:

   This example command changes the thread pool attributes:

   • Using Jacl:

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

   • Using Jython:

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

   This example modifies the property of the first listener port:

   Using Jacl:

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

   • Using Jython:

     lports = AdminConfig.showAttribute(mls, 'listenerPorts')
     cleanLports = lports[1:len(lports)-1]
     lport = cleanLports.split(" ")[0]
     AdminConfig.modify(lport, [['maxRetries', 2]])

   This example adds a listener port:

   Using Jacl:

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

   • Using Jython:

     new = AdminConfig.create('ListenerPort', mls, [['name', 'my'], 
     ['destinationJNDIName', 'di'], ['connectionFactoryJNDIName', 'jndi/fsi']])
     print new
     print AdminConfig.create('StateManageable', new, [['initialState', 'START']])

   Example output:

   my(cells/mycell/nodes/mynode/servers/server1:server.xml#ListenerPort_1079471940692)
   (cells/mycell/nodes/mynode/servers/server1:server.xml#StateManageable_107947182623)

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

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