Send-then-commit, sync level=none, transaction terminated from the program

The send-then-commit flow sends IMS output before IMS completes sync-point processing.

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

Figure 1. Send-then-commit, sync level=none (transaction terminated from program) flow
begin figure description. Diagram flow chart of Send-Then-Commit, Sync Level=None (Transaction Terminated from Program) as described in the 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.
  • The transaction is terminated from the program.
  • IMS Connect will close the socket as soon as Commit confirmed has been sent by IMS.
