Hi,

- WMQI 2.1 CSD 07 on Windows 2000.

- We are processing messages (hundred of thousands) via a simple flow. I've got standard generic error handling in place (wired to the Input Node Catch Terminal) and a trace node which removes the "poison" message from the queue (wired to the Input Node failure terminal) once the rollback occur to the input queue.

- In my current scenario we need all messages to go sequentially to the target system (in the order that it landed on the input queue). We thus need a way to stop the message flow from proccessing subsequent messages from the input queue once an exception occurs in the flow, fix the error and then continue processing.

- Does anyone know of an automated way in which I can achieve this or suggest an alternate approach?

Thx

You can create a PCF message using ESQL that will get-disable your input queue.

Then the messages won't get processed until someone manually reenableds the queue for getting.
