In a previous posting I described how you could use composite sensors to enable end-to-end tracking for messages that move through the Oracle Fusion Middleware SCA engine and the B2B engine.
Today, I discovered that you can also use ECID for end-to-end tracking. The B2B application message contains all the tracking properties that are originated from the SCA composite that submitted the message to the B2B engine. With the B2B Report console you are able to search for messages using the ECID. To enable searching on ECID, you have to add the ECID search field to the search panel (use the Add fields button ):
So, the ECID also enables end-to-end message tracking in Oracle Fusion Middleware 11g when message move through the B2B engine. This time completely out-of-the-box.
UPDATE 25-11-2O09: The application message holds the fabric data for in and outbound message from the SCA FMW11g fabric [OLD Disclaimer: I only tested it for outbound communication using the native B2B adapter. Still have to test it for inbound communication and AQ and JMS interfacing with the B2B engine.]
