Check if user is connected

Question

Hi,
How can i check if the current user is connected in oracle 10g?
In forms 6i, we used to following check to know if the user is connected or not:
if get_application_property (DATASOURCE) = 'ORACLE' then
p_boolean := true;
else
end if;
In 10g, this check returns "ORACLE" even if not connected !
Thanks in advance

Try it:
FUNCTION NotLoggedOn RETURN boolean IS
  Dummy varchar2(1);
BEGIN
  select 'x' into dummy from dual;
  return FALSE;
EXCEPTION
  when OTHERS then
    if SQLCODE in (-1012, -- Not logged on
                    -28,   -- Your session has been killed
                    -3114  -- Not connected to ORACLE
                    ) then
      return TRUE;
    end if;
    raise;
END;Regards
