Set a new topic for the WebSphere MQ messaging provider using scripting

Use scripting to configure a new topic for the WebSphere MQ messaging provider.

We can also use the createWMQTopic to create a queue for the WebSphere MQ messaging provider.

Before starting this task, wsadmin must be running. See the Start wsadmin article for more information.

Perform the following steps to configure a new topic for the WebSphere MQ messaging provider:

 

1. Identify the parent ID:
   • Jacl...

     set newjmsp [$AdminConfig getid /Cell:mycell/Node:mynode/JMSProvider:JMSP1/]

   • Jython...

     newjmsp = AdminConfig.getid('/Cell:mycell/Node:myNode/JMSProvider:JMSP1') print newjmsp

   For example...

   JMSP1(cells/mycell/nodes/mynode|resources.xml#JMSProvider_1)

2. Get the required attributes:
   • Jacl...

     $AdminConfig required MQTopic

   • Jython...

     print AdminConfig.required('MQTopic')

   For example...

   Attribute Type name String jndiName String baseTopicName String

3. Set up the required attributes:
   • Jacl...

     set name [list name MQT]
     set jndi [list jndiName jms/MQT]
     set baseTN [list baseTopicName "Put the base topic name here"]
     set mqtAttrs [list $name $jndi $baseTN]

     For example...

     {name MQT} {jndiName jms/MQT} {baseTopicName {Put the base topic name here}}

   • Jython...

     name = ['name', 'MQT']
     jndi = ['jndiName', 'jms/MQT']
     baseTN = ['baseTopicName', "Put the base topic name here"]
     mqtAttrs = [name, jndi, baseTN]
     print mqtAttrs

     For example...

     [[name, MQT], [jndiName, jms/MQT], [baseTopicName, "Put the base topic name here"]]

4. Create a topic for the WebSphere MQ messaging provider:
   • Jacl...

     $AdminConfig create MQTopic $newjmsp $mqtAttrs

   • Jython...

     print AdminConfig.create('MQTopic', newjmsp, mqtAttrs)

   For example...

   MQT(cells/mycell/nodes/mynode|resources.xml#MQTopic_1)

5. Save the configuration changes. See the Saving configuration changes with wsadmin article for more information.
6. In a network deployment environment only, synchronize the node. See the Synchronizing nodes with wsadmin article for more information.

 

Example

AdminTask.createWMQTopic('DRAPERDCell01(cells/DRAPERDCell01|cell.xml)', '[-name MQQueue -jndiName jms/MQQueue -topicName TopicName -qmgr QueueManager -description ]')
