Retrieving replies from asynchronous ECI requests
Callbacks and reply solicitation calls can be used to retrieve replies from asynchronous ECI requests.
Callbacks enable the CICS® server to drive specific function provided by the user application when an asynchronous program link call completes. Callbacks are not available for all APIs.
Reply solicitation calls
- Retrieves all replies for any outstanding ECI request.
- Retrieves a reply for a specific ECI request. A unique message qualifier is used to identify the reply for that request. Depending on the API that the application uses, message qualifiers are either automatically generated or a they have to be manually assigned to each asynchronous call within a single application.
