Cluster Configuration

To establish connections between the brokers in a cluster at startup time, each broker must be passed the host names and port numbers of all the others (including the master broker, if any). This information is specified by a set of cluster configuration properties, which should be the same for all brokers in the cluster. Although you can specify the configuration properties for each broker individually, this approach is error-prone and can easily lead to inconsistencies in the cluster configuration. Instead, it is recommended that you place all the configuration properties in one central cluster configuration file that is referenced by each broker at startup time. This ensures that all brokers share the same configuration information.

See Cluster Configuration Properties in Sun Java System Message Queue 3.7 UR1 Administration Guidefor detailed information on cluster configuration properties.

Although the cluster configuration file was originally intended for configuring clusters, it is also a convenient place to store other properties that are shared by all brokers in a cluster.
