Hi all,
A beginner's question: in MQInput terminal, what's difference between Fail Terminal and Exception Terminal? When is one fired over other?
Many thanks

Don't know what you mean. I remember 3 terminals
- fail terminal
- out terminal
- catch terminal
Can you please determine what you mean with Exception terminal??

What does the IBM supplied documentation say on the matter?
Or is it a case of 'goodness gracious me, IBM have forgotten to document this most important bit of Information'?

Every time you reinvent the wheel the more square it gets (anon). If in doubt think and investigate before you ask silly questions. |

Btw, I really read the Knowledge Center before posting here. It says: "If an error occurs, the flow goes to Fail terminal. If an exception occurs, the flow goes to Catch terminal." Maybe I should understand the difference between Error and Exception. Let me see the KC again... |

The biggest difference between fail and catch terminal is in the transaction handling.
When the catch terminal is called you are still within the same transaction and all actions up to this point can still be committed.
When the fail terminal of the input node is called the transaction has been rolled back.
This is the reason most of the catch branches end with a throw node.

I'll accept the sarcasm. However
If you had explained your current understanding of the differences then if they were wrong then you might have had the correct information passed to you.
For example
