I Came across this post when I was looking for option on how to implement sequencing solutions with OSB when using messaging (JMS)
https://forums.oracle.com/thread/2138854 Which talks about Using Message Unit-of-Order with JMS
Using Message Unit-of-Order
Message Unit-of-Order is a WebLogic Server value-added feature that enables a stand-alone message producer, or a group of producers acting as one, to group messages into a single unit with respect to the processing order. This single unit is called a Unit-of-Order and requires that all messages from that unit be processed sequentially in the order they were created.
Oracle documentation http://docs.oracle.com/cd/E12840_01/wls/docs103/jms/uoo.html
Doesn’t give us an as is solution but is definitely worth exploring on these lines…
