1. IBM MQSeries

2. History The first messaging and queuing product developed at 1992 for UNIX, VMS, and Tandem. After IBM announced the MQI as one of its standard APIs for program-to-program communication, the product actually tested in a bank for communication between VMS systems and the headquarter that was using an IBM main frame. After that, gradually the product implemented on AS/400, SCO UNIX, UnixWare, AIX, OS/2, and other platforms. Today – MQSeries runs on over 35 platforms.

3. A product for cross-network communication MQSeries is an IBM product that supports the transfer of messages between applications within an OS Image and/or between applications widespread across systems in a network comprising variety of platforms.

4. The Messaging and Queuing programming style enable programs to talk to each other across a network of unlike components— processors, operating systems, subsystems, and communication protocols—using a simple and consistent application programming interface.

5. Why “Messaging and Queuing”?  Messaging: because programs communicate by sending each other data in messages rather than by calling each other directly.  Queuing: because the messages are placed on queues in storage, so that programs can run independently of each other, at different speeds and times, in different locations, and without having a logical connection between them.

6. One-way communication. Program A sends a message to program B via Queue 1.

7. Two-way communication between programs (optional).

8. Either program can be busy or unavailable.

9. One-to-many relationship between programs.

10. Many-to-one relationship between programs.

11. All The program-to-program relationships combined.

12. There are no constraints on application structure.

13.
