LocalController

Install one LocalController on each physical server in the cluster where a subcomponent (an Engine or a Presenter) resides. A LocalController performs the following actions:

• Provides the communication mechanism for subcomponents that are installed on the server.
• Monitors heartbeat messages for subcomponents on the local server and automatically restarts subcomponents if they fail.
• Uses a delivery service to process output from the Engine subcomponents. This service delivers XML documents in a compressed and encrypted format to a local or remote Presenter subcomponent.
