ASYNCHRONOUS PROCESSING - IBM Mainframe

Asynchronous processing provides a means of distributing the processing that is required by an application between systems in an intercommunication environment. Unlike distributed transaction processing, however, the processing is asynchronous.

In distributed transaction processing, a session is held by two transactions for the period of a "conversation" between them, and requests and replies can be directly correlated.

In asynchronous processing, the processing is independent of these cessions on which requests are sent and replies are received. No direct correlation can be made between a request and a reply, and no assumptions can be made about the timing of the reply.
