Hi,

Is anybody share the code for trigger which can raise application of Access Denied, If any user is trying to login to the database from the table which is called "restricted_table". The "restricted_table" contain the user id's that are not allowed to login into the database. So, whenever the that user will login, raise application of access denied.

thanks in advance
qasim

If you really need the login trigger thing - it would be similar to this untested code...
CREATE OR REPLACE TRIGGER dba.logon_restrict_trg
after logon on database
declare
 v_cnt number;
begin
  select count(*) into v_cnt from restricted_table where upper(restricted_user) = upper(ora_login_user);
  if v_cnt > 0 then
    raise_application_error (-20501, 'ERROR: Login using '||ora_login_user||' prohibited');
  end if;
end;
/


As far as I remember, login triggers don't fire for users with DBA priv. (in all versions).

I will brief little bit more about my problem. If the information of that person matches with osuserid and schema of the table then that person can login and send his information to the login audit table. If it does not match then it should raise error of access denied.

Thanks again
