This book describes intercommunication between WebSphere MQ products. It introduces the concepts of intercommunication; transmission queues, message channel agent programs, and communication links, that are brought together to form message channels. It describes how geographically separated queue managers are linked together by message channels to form a network of queue managers. It discusses the distributed-queuing management (DQM) facility of IBM(R) WebSphere MQ, which provides the services that enable applications to communicate via queue managers.
DQM provides communications that conform to the WebSphere MQ Message Channel Protocol. Each WebSphere MQ product has its own implementation of this specification, and this book is concerned with these implementations.
