Based on WebSphere MQ transceiver news program

Abstract: This paper summarized in the following several aspects of the company's commercial communications IBM WebSphere MQ middleware, first of all, to explain the news, Queue and Queue Management for the significance of this icon adopted on the basis of the WebSphere MQ expounded by conducting communications using communication mechanisms, as well as the communication mechanism of the communication and the relationship between the applications. Followed by an example to illustrate the use of Java in the preparation process, how to write news queue. Finally a brief introduction to the advantage of MQ and development prospects.

Key words: communication middleware, queue, queue management, MQ

WebSphere MQ (hereinafter referred to MQ) is IBM's prestigious commercial communications middleware. It is a worldwide widely used in many large enterprises. It provides an industry-standard, secure, reliable messaging system. MQ from a basic messaging system and an application interface. MQ applications using the API (Message Queue Interface MQI) function and Queue Management (MQ run time of the procedure) communications. Queue Manager at work, it needs to use objects such as queues and access. At the same time, Queue Manager is an object. Figure 1 shows the MQ application in the run-time icon.

News is an information unit, which was composed of two parts: a process to another process, the application data as well as news or information described at first.

Descriptors used to identify news sources (message ID), it also includes some control information, such as source type, time expired news, news priority, and so on.

The maximum length of a message for the 100 MB, the biggest news default length of 4 MB. News depends on the maximum length MQ version. MQ support for the fifth edition of the news maximum length of 100 MB.

Queue is a safe storage news, information storage is generally sequential. Because the information stored in the queue, so applications can be at different speeds at different times, different locations and independent operations.

Message Queue communication between applications is a way of communication. Specific applications in the absence of physical connections or connect circumstances, can be passed into the queue to read out information or communication, that is, not through mutual process between calls, but through the queue to send data communication. In this communication mode, the application does not need a complicated. For asynchronous messaging, procedures do not specifically sent to the back-awaited updates, but can be dealt with under an event. Correspondingly is synchronous communication in dealing with the news of an event before it has been waiting for the return updates. For users, the underlying agreement is transparent. Users only need to consider conversation or data entry procedures.
