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

Managing the SCA.SYSTEM bus topology

The service integration bus, SCA.SYSTEM.cell_name.Bus, is used to deploy SCA modules. You can display the local topology of the bus, change the properties of the bus, add servers and clusters as bus members, and perform other administrative tasks to manage the overall topology.

Why and when to perform this task

If you create a Complete (default) installation for WebSphere ESB, you get a stand-alone node in its own administrative cell. The node hosts one server that is assigned to the SCA.SYSTEM service integration bus for the cell.

This bus topology is adequate to deploy SCA modules for some application integration scenarios, but you may want to change the bus topology to take advantage of using more than one member in a bus, or of using more advanced environments involving multiple service integration buses and perhaps links to WebSphere MQ.

If you create a deployment manager profile, you can add managed nodes to the deployment manager cell, and create one or more servers or server clusters on those nodes, as members of the SCA.SYSTEM bus, to deploy SCA modules.

When created, the SCA.SYSTEM bus and servers are assigned values for only some of the important properties, with other properties taking default values.

Use the information in the following sub-topics to display the topology and properties of the SCA.SYSTEM bus and servers, to configure them to your needs, and to manage their runtime state. These sub-topics are aimed at routine tasks to support the deployment of mediation modules into the SCA.SYSTEM bus. These tasks, and other tasks, for the general management of the server and bus environment are provided in the list of related tasks and under Doing more with bus topologies.

When managing the SCA.SYSTEM bus and servers, you consider a variety of issues, including the following:

Remember: Your bus environment might be a combination of several bus topologies. For example, if you create several WebSphere ESB stand-alone profiles or deployment manager profiles, each profile has a separate cell (with its own SCA.SYSTEM bus). You might have some buses with a single server, and other buses with several servers and server clusters.
