Dear Mladen,
Thanks for your response.
SYS and REPADMIN users are keep on LOGGING-IN and LOGGING-OUT periodically
in the background.
That is why SYS user got deleted(when automatic LOG-OUT happens).
Anyway I'll try auditing feature as you suggested.
Thanks again,
Sami

What happens is that you have a database wide logon trigger,
not just a trigger on scott.schema which needs an execution context.
A pseudo session with a SID=0 is established and the trigger is executed.
Personally, I would use auditing ("audit session" or "audit session by
scott"),
not a database trigger.
