If I wire two different paths to a single output node do they each receive identical copies of message or is one of the paths dependent on what the other path changes depending on which one is executed first?
Same question for Flow Order, does First and Second have the same copy of the message?
thanks |

It Depends on your message flow. For example,
A node will receive identical copies of the messages if both the paths originate from single source and you do only lookup in each path.
Let's say there is a compute node in first path, which modifies the input message; in this case the messages received by this node will not be identical.

Yes.

| what if I change the MQMD on one path. I am setting expiry on all reply messages I send back but wanted to ensure I never set it by mistake for any request messages. My error routine has an output node followed by a compute node. Then the output from this compute node has two paths, one that handles sending a reply msg back to the client with the error and the other copies the original message and tags on the error stuff to store else where. The reply message sets the mqmd.expiry but the other copy of the msg does not. |

I am sure if you will send the second message to some output Q directly, you will get correct data.
Somewhere you remove or change MQMD after splitting. May be you copy message body and not entire message.
Anyway Flow Order node and duplicated connectors create identical copies of the messages.

Decided I should test this out.
Here are the results for anyone who cares.
I set up 2 tests, the first connecting 2 paths to the same output node and the second using the Flow Order Node. The test results were identical for both except of course the first test followed the 2 paths in random order where as the Flow Order determines the order.
In each path I set:
OutputRoot.MQMD.Expiry
Environment.abc
OutputRoot.BLOB.BLOB
In both tests, the MQMD.Expiry and OutputRoot.BLOB.BLOB were reset to the original values at the start of each path and the Environment.abc kept it's value. |

Of course...
Now use your regular flow and move output node step by step and find where you change MQMD.
