IBM WebSphere MQ Client Overview

An IBM WebSphere MQ client is part of the IBM WebSphere MQ product that can be installed on its own, on a separate machine from the MQ server. You can run an IBM WebSphere MQ application on an IBM WebSphere MQ client, which interacts with one or more IBM WebSphere MQ servers. The IBM WebSphere MQ client connects to queue managers by means of a communications protocol. The servers to which the client connects might or might not be part of an IBM WebSphere MQ cluster.

The queues and other IBM WebSphere MQ objects are held on a queue manager that you have installed on an MQ server machine. When the application issues a client call, the IBM WebSphere MQ client directs the request to a queue manager, where it is processed and from where a reply is sent back to the IBM WebSphere MQ client. The link between the MQ application and the IBM WebSphere MQ client is established dynamically at runtime.
