How the client connects to the server

A client connects to a server using MQCONN or MQCONNX, and communicates through a channel.

An application running in the IBM® WebSphere® MQ client environment must maintain an active connection between the client and server machines.

The connection is made by an application issuing an MQCONN or MQCONNX call. Clients and servers communicate through MQI channels, or, when using sharing conversations, conversations each share an MQI channel instance. When the call succeeds, the MQI channel instance or conversation remains connected until the application issues a MQDISC call. This is the case for every queue manager that an application needs to connect to.
