Overview of the bus environment

The bus environment comprises an one or more service integration buses, ESB servers, and their resources, organized into logical administrative domains of cells and nodes.

If you create a Complete (default) installation for WebSphere Process Server, you get a stand-alone server on which you can deploy Service Component Architecture (SCA) modules without having to do any configuration of the server.

However, administrators might still want to act on the bus environment, so would benefit from some detail about the environment.

Both the server and SCA.SYSTEM are configured with default properties that might be suitable for you to deploy and run your SCA modules.

Figure 1. A bus environment with one server assigned to the SCA.SYSTEM service integration bus. As a bus member, the server is assigned one messaging engine, which has a data store for storing state data and messages. This figure also shows a mediation module deployed into the bus environment and assigned to the bus member.
A bus environment that comprises one service integration bus. The bus contains one ESB server as a bus member that provides the messaging engine for the bus.
For more advanced usage, you might want to change the configuration of the bus environment for a stand-alone server, or create a bus environment for a deployment manager cell. For example:

Besides the SCA.SYSTEM bus used for SCA modules, you can also create other service integration buses that you can use to support the service integration logic provided by the modules. For example, the SCA.APPLICATION.cell_name.Bus is provided and used to define JMS queue destinations and other JMS resources for modules deployed with JMS bindings.

You can create other buses for use as in WebSphere Application Server; for example, for applications acting as service requesters and providers within WebSphere Process Server, or to link to WebSphere MQ. You can also use a WebSphere Process Server deployment manager to manage separate application servers for use with applications and modules deployed onto WebSphere Application Server.
