The Confirm adapter command (-CONFIRM) is used only on data sources receiving certified messages to specify that confirmation is explicit (non-automatic).

After successful completion of the map, the adapter sends a confirmation to the sender that the message was successfully received. The Certified Session Name adapter command (-CMN) must also be specified. If the Confirm adapter command (-CONFIRM) is not specified, confirmation occurs automatically upon receipt of a message.
