Websphere Message Broker v7 (will be referred as WMB7 in this blog) has very few components compared to v6x. fewer interacting components means fewer opportunities for failure. WMB7 has only one component, that is Broker. Broker database, Config Mgr, User Name Server are no longer required. Brokers create and manage configuration data and deployed resources in an internal repository in the local file system. Commands have been added to back up and restore broker configuration for the purposes of disaster recovery.
