Message channels

 

Message channels are the channels that carry messages from one queue manager to another.

Do not confuse message channels with MQI channels. There are two types of MQI channel, server-connection and client-connection. These are discussed in WebSphere MQ Clients.

The definition of each end of a message channel can be one of the following types:

• Sender

• Receiver

• Server

• Requester

• Cluster sender

• Cluster receiver

A message channel is defined using one of these types defined at one end, and a compatible type at the other end. Possible combinations are:

• Sender-receiver

• Requester-server

• Requester-sender (callback)

• Server-receiver

• Cluster sender-cluster receiver

Detailed instructions for creating a sender-receiver channel are included in the Quick Beginnings book for your platform (not applicable to z/OS). Examples of the parameters needed to set up sender-receiver channels can be found in this book, in the Example Configuration chapter applicable to your platform. For the parameters needed to define a channel of any type, see the DEFINE CHANNEL command in WebSphere MQ Script (MQSC) Command Reference.
