concepts of MQ:
1) Queue Manager
The queue manager is a top-level concept in the MQ system. It provides queue-based message services for us.
2) messages

three examples in this article use Twitter, but you can also use other social networking sites with APIs. Examples of these three mq-twitter are:
A simple queue in which text messages are retrieved from here and posted directly to Twitter

Stack. 2.5 Message Communications
Message communication means that Message Queuing generally has an efficient communication mechanism built into it, so it can also be used in pure message communication. such as the implementation of point-to-point Message Queuing, chat room
The company's technology platform in the docking of IBM MQ message middleware with a broker, messages sent to MQ have more message header information:RHF2, resulting in the reception of the message is not working properly. Record how this problem is handled here.A parameter,
Abstract: This article briefly introduces IBM's commercial communication middleware WebSphere MQ from the following aspects. It first explains the significance of message, queue, and queue manager, on this basis, the illustration illustrates the communication mechanism adopted by WebSphere
provides a message service to an application, and if the queue manager is likened to a database, the queue is one of the tables.
4. Channels (channel)
A channel is a one-way point-to-point communication connection between two managers, and a pair of channels can be established if two-way communication is required.
