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 Start the wsadmin scripting client article for more information.

 

Overview

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

 

Procedure

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

   Use Jacl:

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

   • Use 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:

   Use Jacl:

   set mls [$AdminConfig list MessageListenerService $server]
   

   • Use 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:

   • Use Jacl:

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

   • Use Jython:

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

   This example modifies the property of the first listener port:

   Use Jacl:

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

   • Use 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:

   Use Jacl:

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

   • Use 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.
