This article describes multi-instance brokers, a feature introduced in WebSphere Message Broker V7 that helps you configure high-availability environments. The feature is based on multi-instance queue managers in WebSphere MQ V7.0.1, which provide multiple instances of a queue manager residing on separate physical servers to provide a highly available configuration. In WebSphere MQ, the multi-instance queue manager's configuration is hosted on shared network storage, so that if the active queue manager fails, another instance automatically assumes the stopped queue manager's configuration and becomes active. Similarly, in Message Broker V7 and V8, a broker's configuration is hosted on network storage to enable the high-availability function.
