Asynchronous event notification to Forms

Is there a way to notify Oracle form of some outside event without having the form to poll for it?
What I want is to let the user submit a request through Oracle form. Oracle form will pass the request to another process to complete the request. When the request is completed, I want the form to be notified of the completion. Of course the user session could have terminated before the request is completed, so it will be nice if the status of the user session can be queried also. Received on Wed Oct 25 1995 - 00:00:00 CET
