I have a requirement to output a large MQ message (possibly bigger than 100M) in the middle of my message flow and out side the UOW of the flow.
I specified "transaction =no and allow segmentation" in the MQOUTPUT node that I used to output the large message. However the message flow fail with MQRC2255.
The explanation of 2255 is
"An MQGET, MQPUT, or MQPUT1 call was issued to get or put a message outside a unit of work, but the options specified on the call required the queue manager to process the call within a unit of work. Because there is already a user-defined unit of work in existence, the queue manager was unable to create a temporary unit of work for the duration of the call."

But I am telling the broker to put the message with transaction=No. I need some help to understand this. Is there any sggestion on how I can fill my requirement?
