You use a WebSphere® MQ server to configure a direct (single bus) connection to a WebSphere MQ for z/OS® queue manager or queue sharing group. For WebSphere Application Server Version 6.1, this must be WebSphere MQ for z/OS Version 6 or later. This section provides information to help you learn how WebSphere MQ server works.
A WebSphere MQ server provides direct connection between service integration messaging engines in WebSphere Application Server and queue managers or queue sharing groups in WebSphere MQ for z/OS. WebSphere MQ server is designed to exploit the high availability, and optimum load balancing characteristics provided by a WebSphere MQ for z/OS network. WebSphere MQ server defines the connection and quality of service properties used for the connection, and also ensures that messages are converted between the formats used by WebSphere Application Server, and those used by WebSphere MQ.
