Gateway Manager

The gateway manager processes every message that flows through an integration gateway and maintains links to the other major integration gateway components, including target connectors, listening connectors, and each of the gateway services.

Listening connectors invoke the gateway manager when they receive a request. The gateway manager uses the messaging objects IBRequest and IBResponse to determine how to route each request.

The gateway manager uses a number of the gateway services during this stage to perform operations such as message validation. The gateway manager then invokes the appropriate target connector based on the content of the message object and waits for a reply from the target connector. When the reply is received, the gateway manager forwards the reply to the calling listening connector.

If an error occurs, the gateway manager uses the error handling service and works with the service to prepare an error reply for the listening connector.
