I 'm using a generic error handler subflow, for all my main message flows. On an exception, I create a message for logging purposes. I then issue a throw, to force roll back of the original message to the InputNode, where the originating messages gets routed to a DLQ.

Problem: The log message I write out gets rolled back and the original message is getting thrown out. How can I rollback the original message while still producing the log message?

Flow: InputNode -> Error Handler Subflow -> ComputeNode

Subflow: InputTerminal -> Filter -> tryCatch -> Compute -> OutputNode -> Throw

Change the transaction mode on the Output node in the error flow.

I had the Transaction Mode set to "Automatic" and changed to "no" I now get both Log message and a rolled back original message.

Thanks

On the topic of error handling, I have found these two links phenomenal (WMQI 2.1). You may be beyond this information...but perhaps insightful to others.
