Buses collection

A service integration bus supports applications using message-based and service-oriented architectures. A bus is a group of interconnected servers and clusters that have been added as members of the bus. Applications connect to a bus at one of the messaging engines associated with its bus members.

In the administrative console page, to view this page click Service integration > Buses.

To browse or change the properties of a listed item, select its name in the list.

To act on one or more of the listed items, select the check boxes next to the names of the items that you want to act on, then use the buttons provided.

To change what entries are listed, or to change what information is shown for entries in the list, use the Filter settings.

A messaging engine manages messaging resources and, through destinations assigned to the messaging engine, provides a connection point to which both local and remote applications connect to access messaging resources on the bus. If you add an application server or a server cluster as a bus member, a messaging engine is automatically created for this new member. If you add the same server as a member of multiple buses, the server is associated with multiple messaging engines (one messaging engine for each bus). You can create additional messaging engines for use with server clusters that are bus members, for availability and scalability reasons. However, in its simplest form a bus can be realized by a single engine.

The functionality of service integration buses comprises the SIB service, which is available on each application server in the WebSphere Application Server environment. By default, the SIB service is disabled, so when a server starts it will not have any messaging capability. If you add the server to a service integration bus, the SIB service is automatically enabled. If required, you can disable the service again by configuring the server.

The bus appears to its applications as if it were a single logical entity, which means applications only need to connect to the bus and do not need to be aware of the bus topology. In many cases the knowledge of how to connect to the bus and which bus resources are defined are handled by a suitable API abstraction, such as the administered JMS connection factory and JMS destination objects
