MQI Channels

An MQI channel connects a WebSphere MQ client to a queue manager on a server machine, and is established when you issue an MQCONN or MQCONNX call from a WebSphere MQ client application. It is a two-way link and is used for the transfer of MQI calls and responses only, including MQPUT calls that contain message data and MQGET calls that result in the return of message data. There are different ways of creating and using the channel definitions (see Defining MQI channels).

Figure 5. Client-connection and server-connection on an MQI channel

An MQI channel can be used to connect a client to a single queue manager, or to a queue manager that is part of a queue-sharing group (see Connecting a client to a queue-sharing group).

There are two channel types for MQI channel definitions. They define the bi-directional MQI channel.

Client-connection channel

This type is for the WebSphere MQ client.

Server-connection channel

This type is for the server running the queue manager, with which the WebSphere MQ application, running in an WebSphere MQ client environment, will communicate.
