Send-then-commit, sync level=confirm, ACK response

This send-then-commit flow assumes no synchronization for the transactions as they are processed by IMS.

The following figure shows a flow in which all transactions are confirmed as they are received (each message requests a response).

begin figure description. Diagram flow chart of Send-Then-Commit, Sync Level=Confirm (ACK Response) as described in the surrounding text. end figure description.
The sample flow shown in the preceding figure assumes the following:
  • Commit mode 1 is specified in the state-data section of the message prefix.
  • The transaction pipe is not synchronized.
  • The synchronization level is specified as Confirm in the state-data section.
  • ACK can be replied to by a remote workstation before the check response requested bit.
