Types of message

 

There are four types of message defined by WebSphere MQ:

• Datagram

• Request

• Reply

• Report

Applications can use the first three types of messages to pass information between themselves. The fourth type, report, is for applications and queue managers to use to report information about events such as the occurrence of an error.

Each type of message is identified by an MQMT_* value. We can also define your own types of message. For the range of values we can use, see the description of the MsgType field in the Application Programming Reference.
