That's a curious assertion. |
Ok, I wouldn't want that.
I stand chided.  |
No, it's curious that you think it's possible to run the flow *without* mqm authority. |

Hello,
I just wanted to share what we found out and which solution we finally chose.
Well, first thing we did was to develop a Proof Of Concept that it is possible to create, use and delete permanent dynamic queues within a message broker flow.
This is how the POC was designed...
We had 3 flows:
1. Creating the dynamic queue, adding the name in the control message (special format used to control the whole process), doing some business transformation etc. and writing output to the dynamic queue. Control message including the name of the dynamic queue was passed to 2nd flow.
2. Flow is triggered by control message, read the data from the dynamic queue via GetNode (encapsulated in a GetMessageSubflow) and processed the data. Control message is passed to 3rd flow.
3. Flow is basically doing some cleanup. In the case of the dynamic queue: the queue was deleted.
The POC proved that the whole usage of dynamic queues within message broker flows is possible.
It also worked in error and restart cases.
Now here´s the but:
In our case the 1st flow is calling a WTX-Map. We reworked the architecture of the WTX-Map and improved the whole process here which made it performing way better and made the 2nd flow completly obsolete. The need to pass the data from flow 1 to flow 2 over dynamic queues (for seperation of the data of several parallel instances) was not there anymore.
Bottom line:
It is possible to use dynamic queues within message broker flows, but in the end we didn´t need it. |

I forgot to tell how we created and deleted permanent dynamic queues:
The creation and deletion of the queues was done in JavaCompute nodes using the ibm pcf api. |
