Send-then-commit, sync level=none

The send-then-commit flow sends IMS output before IMS completes synchronization-point (hereafter referred to as sync-point) processing.

To use the send-then-commit flow, specify commit Mode 1 in the state-data section of the message prefix.

begin figure description. Diagram flow chart for Send-Then-Commit, Sync Level=None as described in surrounding text. end figure description.
The sample flow shown in the above figure assumes the following:
  • The transaction pipe is not synchronized.
  • The synchronization level is specified as NONE in the state-data section of the message prefix. Therefore, IMS does not request a response (an ACK) when sending output.
