Hi,

My task is to dequeue message if it is past 30 minutes after it has been qued. ie. How can I check the record in queue table if it has passed 30 minutes( should I take into account the enque time stamp?)

Iam new to advanced queue, I would appreciate if someone can provide me an example.

Thanks

When you dequeue, check the value of message_properties_t.enqueue_time.

How about enqueuing the message with a delay?
At the time of enqueue, you specify a time 30 minutes in the future.
The message remains in the queue with a state=1 until the delay time is reached where one of the aq_tm_processes converts it to an active event (state=0) and it's available for dequeue.
