What is a message?

 

In message queuing, a message is a collection of data sent by one program and intended for another program.

WebSphere MQ defines four types of message:

Datagram	A simple message for which no reply is expected
Request	A message for which a reply is expected
Reply	A reply to a request message
Report	A message that describes an event such as the occurrence of an error

See Types of message for more information about these message types.
