If you want to restrict all or most users based on time, the simplest way to do that is to enable/disable oracle restricted session, and only grant the restricted session privilege to those whom you want to allow to log in. -----Original Message----- From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Jay.Miller@xxxxxxxxxxxxxxxx Sent: Friday, October 12, 2007 3:42 PM To: oracle-l@xxxxxxxxxxxxx Subject: Disconnecting session from an on logon trigger I'd like to create an on logon trigger that will prevent the user from connecting in certain circumstances. I have one way of doing it which would be to issue execute immediate ' alter system kill session 'session_id', 'serial#'' but I can't help but wonder if there's a cleaner way to do it from within oracle instead of killing the session?
