How to send a message to another queue manager

This section describes the simplest way to send a message between queue managers, including prerequisites and authorizations required. Other methods can also be used to send messages to a remote queue manager.

Before you send a message from one queue manager to another, we need to do the following steps:
  1. Check that your chosen communication protocol is available.
  2. Start the queue managers.
  3. Start the channel initiators.
  4. Start the listeners.

You also need to have the correct IBM MQ security authorization to create the objects required.

To send messages from one queue manager to another:

  • Define the following objects on the source queue manager:

    • Sender channel
    • Remote queue definition
    • Initiation queue ( required on z/OS, otherwise optional)
    • Transmission queue
    • Dead-letter queue

  • Define the following objects on the target queue manager:

We can use several different methods to define these objects, depending on the IBM MQ platform:

See the following subtopics for more information on creating the components for sending messages to another queue manager:

  • Defining the channels
    To send messages from one queue manager to another, we must define two channels. We must define one channel on the source queue manager and one channel on the target queue manager.
  • Defining the queues
    To send messages from one queue manager to another, we must define up to six queues. We must define up to four queues on the source queue manager, and up to two queues on the target queue manager.
  • Starting the channel
    When you put messages on the remote queue defined at the source queue manager, they are stored on the transmission queue until the channel is started. When the channel has been started, the messages are delivered to the target queue on the remote queue manager.
