SQL & PL/SQL

Hello,

I have a procedure that calls a lot of procedures, functions, packages in 9i database.
I'm trying to send an email with the error information whenever an error prevents the procedure to execute with success.

I searched something about this and i'm using this code for trapping the possible error:

EXCEPTION
WHEN OTHERS THEN
DBMS_OUTPUT.PUT_LINE('ERROR');
DBMS_OUTPUT.PUT_LINE ('error code ' || SQLCODE);
DBMS_OUTPUT.PUT_LINE ('error MESSAGE ' || SQLERRM);
DBMS_OUTPUT.PUT_LINE ('ERROR STACK:' ||DBMS_UTILITY.FORMAT_ERROR_STACK);
END;

But in this information is missing the exactly program (function, procedure or package) and line number.

I could do this using

DBMS_OUTPUT.PUT_LINE ('ERROR BACKTRACE:' || DBMS_UTILITY.FORMAT_ERROR_BACKTRACE);

But i think is not available on database 9i.

How can i get this kind of result in database 9i?

Thank you.
Rute
