5.5.5 WebSphere Application Server, WebSphere MQ Server and HACMP
Although the WebSphere Application Server Network Deployment environment fully supports messaging from within the JVM instance, the use of a full WebSphere MQ Server 6 configuration is still supported and may be preferable for some environments.
However, in this environment HAManager cannot be used because there are multiple WebSphere MQ processes that run outside of the JVM process at the operating system image level. In this situation, HACMP must be used to fail over the active WebSphere MQ Server instance to a standby copy, probably using PPRC to mirror any data and remount any storage.
HACMP can also be used to failover the WAS instance itself for some environments, such as for the Node Agent and Deployment Manager that manage the clusters.
