Control Flow

The RFC adapter loads its configuration from a file (for example, adapter_config.xml) and validates it against the adapter schema (framework.xsd).

The Adapter Controller creates an instance of the RFC adapter, and receives and executes start and stop commands.

SAP RFC Input Adapter Control Flow

SAP RFC Output Adapter Control Flow

• Start Command
  When the start command is executed, it configures and starts the command and control interface, starts the adapter, establishes a connection to an SAP system, and connects the ESPPublisher and ESPSubscriber components to Event Stream Processor via the SDK interface.
• Stop Command
  When the stop command is executed, it disconnects the ESPublisher and ESPSubscriber components from Event Stream Processor, waits until all the buffered rows between the modules are processed, disconnects the adapter from the SAP system, and terminates the adapter process. You can also execute the immediatestop command which is the same as the stop command except that it discards the buffered rows and stops adapter immediately.
