Destination Bridges


Ø  An application can process messages so that they are sent multiple times to the required destinations. However, such processing requires significant coding effort in the application.
Ø  EMS provides a server-based solution to this problem. You can create bridges between destinations so that messages sent to one destination are also delivered to all bridged destinations.
Ø  Bridges are created between one destination and one or more other destinations of the same or of different types. That is, you can create a bridge from a topic to a queue or from a queue to a topic. You can also create a bridge between one destination and multiple destinations. For example, you can create a bridge from topic a.b to queue q.b and topic a.c.
Ø  Specify a bridge on topic foo.* to queue foo.queue, messages delivered to any topic matching foo.* are sent to foo.queue.











Ø  When a bridge exists between two queues, the message is delivered to both queues. The queues operate independently; if the message is retrieved from one queue, which has no effect on the status of the message in the second queue.
Ø  Creating a Bridge: Bridges are configured in the bridges.conf configuration file.
