Administer service integration buses
Application servers or clusters of application servers in a WAS cell can cooperate to provide asynchronous messaging services. Service integration provides asynchronous messaging services, and a group of servers or clusters that cooperate in this way is called a service integration bus. Each of the cooperating servers or clusters is made a member of the bus. In the simplest case, a service integration bus consists of a single bus member, which is one application server.
