IBM Rational Test Virtualization Server stubs designed in IBM Rational Integration Tester are published to Rational Test Control Panel, which holds them in a repository. Rational Test Control Panel users can control stubs by means of web pages; and Rational Test Control Panel also manages the Rational Test Virtualization Server environment so that, where possible, messages are routed automatically to the stubs. (For more information about stubs, refer to Virtualization testing using Rational Test Virtualization Server.)
Rational Test Control Panel also enables you to schedule the execution of test suites on a single schedule basis or a recurring schedule basis.
If you are using any of the proxies in the IBM Rational Integration Tester Platform Pack, you will have to install and configure Rational Test Control Panel because it provides a central registration point for the proxies so that multiple instances of Rational Integration Tester can find and communicate with them.
The following diagram shows how Rational Test Control Panel might be deployed in a Rational Test Virtualization Server Environment.
