Hi Jim, I knew how the recovery db would handle the messages. But it takes some time for the recovery database to process all the queued messages but what happens when during that processing a real time message is received? Does the system proces that message AFTER the processing of the message in de REQ DB or simultaneously? if it’s after the order from the sending system can be guaranteed. If is simultaneous the order can’t be guaranteed since a realtime ADT-A03 can be processed real time while the ADT-A01 (or an A02) can still be in the queue of the REQ DB.
The receiving system gets a discharge message for a patient that is not yet admitted, so it will not be processed then later on when the A01 from the recovery is sent it will admit the patient and will never receive a discharge again.
