Do all XI Adapters support transactionality?

Do all XI Adapters support transactionality?

Hello,

As the subject tells you, my question is: Do all XI Adapters support transactionality?

I'd like to know this for the following adapters:

- RFC

- IDoc

- File Adapter

- Database (JDBC) Adapter

- SOAP Adapter

- Plain HTTP Adapter

Thanks & Regards,

Bas.

    Bas,

    The adapter engine has no direct support for 'transactions'.

    HTTP/SOAP

    If you send a message to XI via HTTP/SOAP, you should re-send the message if the result code <> 200. To avoid that XI processes the message twice, you should specify a unique message-id (GUID). For HTTP, you specify a message-id in the URL; for SOAP, you specify it in the SOAP header.

    For JMS, the adapter engine does duplicate detection based on the JMS message id. Having tested the JMS adapter under stress conditions, no messages were lost. The JMS adapter reconnects nicely and continues processing.

    Kind regards, Guy Crets

    Dear BvH,

    XI and the adapter engine do not support transactionaly in the scence like an XA-Specification. It ist not an transaction monitor! Therefore the system is losely coupled and there is retry mechanism from the adapter engine to ensure that the data will be guaranteed to bo send to the receiver.
