Процедура на pl/sql имеет следующий вид:

PROCEDURE MAIN IS
jobno NUMBER;
BEGIN
dbms_job.submit(jobno,'PROBA.MAIN',to_date ('08.04.2003','dd.mm.yyyy'),'add_months(sysdate,1)');
dbms_output.put_line(to_char(jobno));
commit;
END MAIN;

На ошибки не ругается. Процедура PROBA.MAIN работает
Запускаю сей шедевр на SQL Navigator-е. Строится процедура запуска:

BEGIN
time_.main;
COMMIT;
EXCEPTION
WHEN OTHERS THEN
dbms_output.put_line(SubStr('Error '||TO_CHAR(SQLCODE)||': '||SQLERRM, 1, 255));
RAISE;
END;

Говорю "давай родимая" и жму кнопалку и получаю в output-e:
9:56:39 Start Executing PL/SQL block ...
9:56:39 Starting execution of PL/SQL block...
