Control Flow

The adapter loads its configuration from a file (for example, adapter.xml) and validates it against the adapter schema (fixadapter.xsd), which includes the API-wide controller schema (controller.xsd).

You cannot edit schemas.

The FIX adapter control flow includes loading different configuration files, and various commands and components.

The Adapter Controller creates an instance of the adapters, and receives and executes user commands. It can execute start, stop, and status commands.

• Start Command
  The start command starts the FIX adapter, configures and starts the command and control interface, loads the FIX dictionary and the SpPublisher and SpSubscriber components, and then connects to the Event Stream Processor via the API interfaces.
• Stop Command
  The stop command causes the Data Source Handler to close the session and disconnect from the datasource, the Adapter Controller to stop listening to user commands, and the adapter process to terminate.
• Status Command
  The status command reports the FIX adapter status, and the Adapter Controller prints out its status: either running or stopped.
