Oracle Reports 11g Release 1 (11.1.1) provides better framework to view the topology of the components.
To view the topology of the instance in Oracle Enterprise Manager:
In the target navigation pane, view the complete Farm and all components in a hierarchical view.
In the target navigation pane, under the Farm node, expand Farm_ClassicDomain > Reports and click the Reports Application, Reports Bridge, Reports Server, or Reports Tools component nodes to display their home pages.
When you select a target, such as a Reports component, the target's home page is displayed in the content pane and the target's menu is displayed at the top. Alternatively, you can right-click on the target to view its menu.
