Concurrent Program not executing

Question

Hi All,
I have created new custom concurrent program of type SQL*Plus to purge the data. To my surprize when I submit the program, program is not getting executed, which I can confirm saying the data is not getting deleted. Also the log messages mentioned script is also not displayed in the LOG.
No debug message is displayed in neither LOG nor OUTPUT.
Executable File Name is correctly given and taken care of all other mandatory stuff while registration.
Bleow the script:
I am passing Number of Days ( 500 ) as parameter to this program.
So here &1 = 500:
DECLARE
L_deleted_rec_cnt NUMBER;
BEGIN
fnd_file.put_line ( fnd_file.LOG, ' Conc Program Starts');
DELETE
FROM xxX_TABLE_NAME
WHERE TRUNC (creation_date) < TRUNC (SYSDATE- &1);
L_deleted_rec_cnt := SQL%ROWCOUNT;
IF L_deleted_rec_cnt > 0 THEN
COMMIT;
fnd_file.put_line ( fnd_file.LOG, L_deleted_rec_cnt||' Records purged');
ELSE
fnd_file.put_line ( fnd_file.LOG, ' No Records to purge');
END IF;
fnd_file.put_line ( fnd_file.OUTPUT, ' Conc Program End');
EXCEPTION
WHEN OTHERS THEN
fnd_file.put_line (fnd_file.LOG, 'Error in purging '||SQLCODE||' '||SQLERRM);
END;
Please advise.
Regards,
Ram
