The start command configures and starts the adapter command and control interface.
The Data Source Handler, which implements the NYSE MAMA and MAMDA Client APIs, connects to the NYSE data feed, initiates a session with it, and downloads the data dictionary. The SpSubscriber and SpPublisher components connect to Event Stream Processor via the SDK interface. SpSubscriber starts listening to the watchlists and SpPublisher is ready to publish data to data streams.
The adapter ignores the start command if it is executed when there is a running instance of the adapter, and a warning is sent.
