I am not sure if there is any such function in 9i . But you can definnitely accomplish this by writing your own function something like

    function isNum(a varchar2) returns boolean is     begin

          b := tonumber(a);
          result = true;
         return result;

    exception
    when (numer or value error) -- get proper exception

         result=false
        return result;

    end;

same can be done for isDate as well.
