I'm using Oracle ODP.Net for enqueue and dequeue.

Process A : Enqueue
Process B : Dequeue with MessageAvailable event

If Process A and B are running, there is no problem. On the "Process B", the event is always fired.

But, if "Process B" is off and "Process A" is on, when "Process B" restarts, the queues inserted during the off time are lost.

Is there an option for to fire the event for all queues inserted in the past ?

Many Thanks
