Hi,
I didn't tried yet, but common sense says it will work.

CREATE TRIGGER SYS.LOGON_muhammed
AFTER LOGON ON SYS.SCHEMA
/

Once of this day I will have to fix several pending security items I
have on my database I discovered recently, like the fact you can
capture with a network monitor the command enabling the role and the
password.

Now I have to develop and certify on java, not to work in database. :)
