The IBM MQSeries family of products is an open and scalable messaging and information infrastructure. The function of the IBM MQSeries products is to provide a means of integrating business processes. The IBM MQSeries family of products is the market leader in commercial messaging.
The products provide time-independent messaging between applications and systems. This characteristic facilitates rapid application integration. The IBM MQSeries products enable programs to talk to each other across a network of disparate components (e.g., processors, operating systems, subsystems, and communication protocols) through the use of a simple and consistent application programming-interface. The major components of the IBM MQSeries are as follows:
MSMQ is a service that facilitates messaging between applications. Messages are sent asynchronously with the guarantee the successful delivery unless notification of the failure to deliver is provided. The message structure is flexible (e.g., arrays of bytes, strings, numbers, and so forth). The asynchronous message sent by MSMQ, however, cannot package the arguments of a method call and ferry it asynchronously from client and server. In contrast, MSMQ is a simple C API, together with a collection of COM objects, developers can use to send information asynchronously in the form of a message from point A to point B with a guarantee of delivery.
3. Designing Message Queuing Applications
Message queuing products provide mechanisms for connecting applications together. There is great flexibility in the development and structure of message queues. This flexibility, however, can create indecision in design choices.
One approach to the simplification of the design process is the use of Design Patterns. A design pattern consists of objects that function together and share information with one another to solve a specific problem within a specific contextual situation. Design patter...
