WebSphere WebSphere Enterprise Service Bus, Version 6.0.1 Operating Systems: AIX, HP-UX, Linux, Solaris, Windows

Choosing a bus environment

If you choose a Complete (default) installation for WebSphere ESB, you get a single-server bus environment. If this is not adequate for your service applications, you can create a bus environment that includes a choice of bus topologies including a multiple-server bus in a deployment manager cell, several single-server buses that use different servers, and other buses for serving applications or linking to WebSphere MQ.

Why and when to perform this task

If you choose a Complete (default) installation for WebSphere ESB, you get a stand-alone node in its own administrative domain, known as a cell. The node hosts one server that is assigned to the SCA.SYSTEM bus for the cell, for you to deploy SCA modules.

If your SCA modules only need one server, you can use the SCA.SYSTEM bus of the Complete (default) installation. If your service applications need more than one server, you need to choose between a variety of bus topologies.

You should choose the bus environment needed for an enterprise service bus before deploying SCA modules, because it affects installation-related actions, including what WebSphere ESB profiles you need to create, and what databases you want messaging engines to use.

Besides using the SCA.SYSTEM bus provided for SCA modules, you can create other application servers and service integration buses to support other applications and modules, or to connect to WebSphere MQ networks. This set of topics is mainly focused on using the SCA.SYSTEM bus to support SCA modules.

Information about using other service integration buses, as in WebSphere Application Server Network Deployment, is provided by links into the WebSphere Application Server topics.

To choose a bus environment, consider the following points and the descriptions of bus topologies given in the sub-topics referred to below.
