Asynchronous request / response

Note: This section needs major work.

PeopleBooks:

  1. A source system generates and sends a request.
  2. The application receives and processes the request.
  3. Sometime later the application sends a response back to the source system. The response includes a unique identifier from the original request, which serves as a correlation ID.
  4. The source system processes the response using the correlation ID to map it back to the original request.

Valid Handler Types:

  • OnNotify
  • OnReceive
  • On Response (???? from pbooks)
  • OnRoute
  • OnRequestSend

The sending system invokes a service operation asynchronously and processes the response from the receiving system asynchronously. Unlike a synchronous operation type, the response is not processed on the same thread as the response, and it is processed sometime in the future.

Outbound:

The application generates and sends a request. The target system receives and processes the request. Sometime later the target system sends a response which contains the transaction ID from the original request. This ID serves as the correlation ID. The application processes the response using the correlation ID to map it back to the original request. The message sent back is a response in the form of a request.

Inbound:

A source system generates and sends a request. The application receives and processes the request. Sometime later the application sends a response back to the source system. The response includes a unique identifier from the original request, which serves as a correlation ID. The source system processes the response using the correlation ID to map it back to the original request.

Example Delivered Service: QAS_QRY_SERVICE QAS_EXECUTEQRYASYNC_OPER - This only has a “OnNotify” handlers
