Acknowledgment Support in the Adapter Engine 

Receiver Adapters

●      System acknowledgments and system error acknowledgments

○       Receiver adapters that run on the Adapter Engine support system acknowledgments and system error acknowledgments if they are requested by the sender.

The acknowledgments are triggered when a message is successfully processed by the adapter or if an error occurs while it is being processed. Several system error acknowledgments may be sent, followed by a system acknowledgment if the retry is successful.

○       The receiver JMS adapter is an exception to this rule.

○       By using a parameter in the configuration, you can specify whether a system acknowledgment is sent like all other adapters or whether a DeliveryAckNotSupported is sent instead.

○       This is recommended if the delivery of the message by the JMS adapter is considered to be too weak to trigger a system acknowledgment.

●      Application acknowledgments and application error acknowledgments

○       Receiver adapters of the Adapter Engine do not support any application acknowledgments.

○       The RNIF and CIDX adapters are exceptions to this rule, since they also support scenario-dependent application error acknowledgments.

●      ApplicationAckNotSupported and ApplicationErrorAckNotSupported

○       All receiver adapters send ApplicationAckNotSupported and ApplicationErrorAckNotSupported.

Sender Adapters

●      Sender adapters of the Adapter Engine do not request any acknowledgments.

●      The RNIF and CIDX adapters also support system acknowledgments, system error acknowledgments, and application error acknowledgments, depending on the scenario.
