Use Database Notification Time (-dbnotifytime) to specify how often a client polls the database for notifications.

n
The time, in seconds, of how often a client polls for notifications. The default is 30 seconds, meaning that clients will poll for notification every 30 seconds. The minimum value is 10 seconds; the maximum is 300 (5 minutes).

Database Notification Time (-dbnotifytime) parameter may be modified while your database is online using PROMON or through the _DbParams VST. When a client next logs in, it will ask the database server to specify the Database Notification Time value and change the value if applicable.

You can use this parameter to support continuous operation of the database. For more information, see Change database parameters while the database is running.
