Exactly once delivery in SAP XI

[Former Member]

Hi all -

Client question:

1. What does "Exactly Once" mean in terms of the JDBC adapter?

2. In terms of an FTP adapter?

3. What constitutes XI's understanding of a successful delivery to the target application?

4. How far does XI go in monitoring the successful posting to the target application?

Throw in your ideas on the above questions.

Hi,

<i>1. What does "Exactly Once" mean in terms of the JDBC adapter?

2. In terms of an FTP adapter?</i> >>>

In General , "Exactly Once" means, message delivery is guranteed. It is of type Asynchronous. So all Asynchronous messages are persisted in XI. So if you have any problem because of Queue stuck etc, you are able to restart/reprocess the messages as it is persisted.

<i>3. What constitutes XI's understanding of a successful delivery to the target application?</i>

>>>System Acknowledgement, i.e in the Asynchrnous communication, XI is responsible to send the message to Receiver system.

>>>XI monitors, till the message is sent to Reciever system. It is not responsible to monitor the processing of messages in Reciever system.

Hope this helps,
