I created a procedure that executes an ALTER USER statement and it works when I run it stand alone. But then I created a trigger that is supposed to fire off this procedure when a before update event on a column of an oracle table takes place. This table is application specific, so I am testing this through the application process. I know the column updated, but the procedure didd not execute. I've got the system privs set to execute any procedure. Created a public synonym for that procedure. <br>Is there a way to trace this event so I debug this problem further. Thank u for yur time.
