Sample OTMA commit processing flows

To show the differences between the two commit modes, the topics listed below show sample flows of data between IMS and clients for each commit mode.

Commit-then-send flow
The commit-then-send flow, also known as the IMS standard flow, enqueues IMS output before sending it to the client. Use this flow for standard transaction processing.
Send-then-commit flow
The send-then-commit (commit-mode 1 or CM1) flow sends IMS output before IMS completes synchronization-point (hereafter referred to as sync-point) processing.
Send-then-commit flow with confirm
The send-then-commit flow assumes no synchronization for the transactions as they are processed by IMS.
