JMS Bridges in High Availability (HA) Broker Clusters

Message Queue supports JMS bridges in HA broker clusters, but some special constraints apply due to the inherent nature of HA broker clusters:

To ensure that bridges in the cluster have the same configuration across all brokers in the cluster, all bridge-related broker properties except for imq.bridge.activelist should be specified in the centralized cluster properties file defined by the imq.cluster.url broker property.

A table in the cluster's HA store is used to maintain a consistent record of JMS bridge ownership by the brokers in the cluster.

During broker startup, the JMS bridge service compares the broker's imq.bridge.activelist property value to this table's entries before starting any JMS bridges, with the following consequences:
