Using DBMS_APPLICATION_INFO.SET_MODULE to get the number of updated rows.

Question

hi.
i have 2 tables to sync so i use the following code. however i included DBMS_APPLICATION_INFO.SET_MODULE to track the number of rows to be updated, but its not showing in v$sessions view. can anyone tell me what am i missing over here ?
DECLARE
l_count NUMBER (20, 0) := 0;
l_updates NUMBER (20, 0) := 0;
l_inserts NUMBER (20, 0) := 0;
BEGIN
FOR i
IN (SELECT date_value,
book_id,
amount
FROM bookstore.book_master_transit)
LOOP
BEGIN
UPDATE bookstore.book_master
SET amount = i.amount
WHERE date_value = i.date_value
AND book_id = i.book_id;
IF (sql%ROWCOUNT > 0)
THEN
BEGIN
l_updates := l_updates + 1;
END;
ELSIF (sql%ROWCOUNT = 0)
THEN
BEGIN
INSERT INTO bookstore.book_master (     date_value, book_id, amount)
VALUES (i.date_value, i.book_id, i.amount);
l_inserts := l_inserts + 1;
END;
END IF;
l_count := l_count + 1;
DBMS_APPLICATION_INFO.set_module ('sync_book_info','total = '|| l_count|| '; updates = '|| l_updates|| '; inserts = '|| l_inserts);
IF (MOD (l_count, 1000) = 0)
THEN
COMMIT;
END IF;
EXCEPTION
WHEN OTHERS
THEN
NULL;
END;
END LOOP;
COMMIT;
END;
when i query v$sessions after running this i couldnt find any entry with the value 'sync_book_info' as the module name. please advice me what i am doin wrong and how to do it right..
thanks in advance,

Totally, 100%, remove & eliminate entire EXCEPTION handler.
Then you will be able to see error being RAISED; like No Privs
