Application Programs and Messaging
The IBM MQSeries range of products provides application programming services that enable
application programs to communicate with each other using messages and queues. This form
of communication is referred to as commercial messaging . It provides assured, one-time-only
delivery of messages. Using MQSeries means application programs can be, so that the
program sending a message continues processing without having to wait for a reply from the
receiver. If the receiver, or the communication channel to it, is temporarily unavailable, the
message can be forwarded at a later time. MQSeries also provides mechanisms for providing
acknowledgements of messages received.
The programs that comprise an MQSeries application can be running on different computers,
on different operating systems, and at different locations. The applications are written using a
common programming interface known as the Message Queue Interface (MQI), so that
applications developed on one platform can be transferred to another. When two applications
communicate using messages and queues, one application puts a message on a queue, and
the other application retrieves that message from the queue.
