Creating destination lists

Create a list of destinations to indicate where a message is sent.

Before you start:

Read the concept topic Message flow nodes.

You can include a Compute node in your message flow, and configure it to create a destination list within the LocalEnvironment subtree. You can then use the destination list in the following nodes:
  • Start of changeThe MQOutput and JMSOutput nodes, to put output messages to a specified list of destinations. End of change
  • The RouteToLabel node, to pass messages to Label nodes.
    For details about how this technique is used, look at the following sample: You can view samples only when you use the information center that is integrated with the Message Brokers Toolkit.

For more information about accessing the LocalEnvironment subtree, destination list contents, and example procedures for setting values for each of these scenarios, see Accessing the LocalEnvironment tree.

For more information about how to populate destination in the LocalEnvironment subtree, see Populating Destination in the LocalEnvironment tree.

You might find it useful to create the contents of the destination list from an external database that is accessed by the Compute node. You can then update the destinations without needing to update and redeploy the message flow.

The use of the destination list to define which applications receive the output messages is in contrast to the publish/subscribe application model, in which the recipients of the publications are those subscribers that are currently registered with the broker. The processing that is completed by the message flow does not have any effect on the current list of subscribers.
