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 framework.xsd file is used by the adapter toolkit, which the adapter is based on, to check for things like missing elements, invalid value types, and so on.

Sample adapter configuration files are located in the various example adapter folders:

Windows: %STREAMING_HOME%\adapters\rfc\examples
UNIX: $STREAMING_HOME/adapters/rfc/examples

The framework.xsd file is located in the %STREAMING_HOME%\adapters\framework\config directory on Windows and $STREAMING_HOME/adapters/framework/config on UNIX.

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