The WebSphere Message Broker system is implemented as a series of message brokers running on different platforms. A group of related message brokers are collectively called a domain and are controlled by a single configuration manager that maintains parameters and configuration status for all brokers under its control. Users and administrators interact with the configuration manager through a desktop toolkit based on Eclipse running as shown in Figure 1-7.
