The Broker Topology editor is the default editor that is provided by the Broker Administration perspective for managing brokers and collectives, and for saving topology changes to the Configuration Manager in a single step.
The Broker Topology editor is launched in the editor area of the Broker Administration perspective when you double-click Broker Topology in the Domains view.
If you are not connected to a domain, a connection attempt is made before opening the editor. During this attempt, if you click Cancel, the connection that is in progress stops and the domain returns to its initial unconnected state.
When the editor is launched, an overview pane is displayed in the Outline view. The Outline view is stacked on top of the Properties view. Use the Properties tab or the Outline tab to select which of these two views is displayed.
Use the Broker Topology editor to do the following tasks:
In the workbench, a broker is a representation of a broker that exists in the domain. When you create or rename a broker in the Broker Topology editor, you must use the name of the physical broker that exists in the domain.
When you create a broker in the workbench, a red cross at the top right of the broker icon indicates that the Queue Manager Name property has not been entered. Right-click the broker, select Properties from the shortcut menu, and then enter the name of the queue manager that the broker uses. You cannot save the topology until you have specified a queue manager for each broker.
The rules for creating a broker topology are given in the Broker Networks section of Publish/subscribe topologies.
When you save topology changes to the Configuration Manager, the topology information in the Domains view on every workbench that is connected to the Configuration Manager is refreshed automatically.

By default, the Broker Topology editor has a background image of a world map. You can change the background image, and modify its scale factor, or choose not to display an image, by following the instructions in Changing Broker Topology editor properties.
