You must run the No Response Action Processor (ALPPNR) concurrent program to check for alert messages whose specified response days have passed without receiving a valid response. After the specified response days have passed, if Oracle Alert never received any response to the alert message or if it received only invalid responses, the No Response Action Processor performs the no response follow-up actions for each message and closes responses for all messages in that response set.

Use Standard Request Submission windows to schedule the No Response Action Processor. This program does not require any parameters. You should run No Response Action Processor at least once a day. See: Running Reports and Programs.
