All, Many years ago (version 9.2) I toyed with this capability of SQL*Net without much luck. Has anyone toyed with it in recent times (11.1.0.7) with much success??? I'm facing an issue where we have web servers in a DMZ that connect back to the database and the firewall has a 24 hour idle timeout, so I end up having to manually disconnect some sessions every day.
