Filewatcher - not recurring

Question

Hi all,
I have used the example given in http://www.oracle-base.com/articles/11g/SchedulerEnhancements_11gR2.php#file_watcher and created a filewatcher. But it triggered only once. The file watcher intervel is set to 1 minute. So as per my below program I should get a record in the out puttable every minute. But it contains only one record. Can someone hellp me to fix this.
BEGIN
  DBMS_SCHEDULER.create_credential(
    credential_name => 'local_credential',
    username        => 'osuser',
    password        => 'ospwd');
END;
BEGIN
  DBMS_SCHEDULER.create_file_watcher(
    file_watcher_name => 'kpi_file_watcher',
    directory_path    => 'd:\jaggy\kpi\csvs',
    file_name         => '*.csv',
    credential_name   => 'local_credential',
    destination       => NULL,
    enabled           => FALSE);
END;
BEGIN
  DBMS_SCHEDULER.create_program(
    program_name        => 'file_watcher_kpi_prog',
    program_type        => 'stored_procedure',
    program_action      => 'file_watcher_kpi_proc',
    number_of_arguments => 1,
    enabled             => FALSE);
END;
BEGIN
  DBMS_SCHEDULER.define_metadata_argument(
    program_name       => 'file_watcher_kpi_prog',
    metadata_attribute => 'event_message',
    argument_position  => 1);
END;
CREATE TABLE file_watcher_output (
  file_name VARCHAR2(100),
  file_size_kb number,
  received_date date
CREATE OR REPLACE PROCEDURE file_watcher_kpi_proc (p_sfwr SYS.SCHEDULER_FILEWATCHER_RESULT) AS
  --l_message file_watcher_output.message%TYPE;
  l_file_name varchar2(100);
  l_file_size number :=0;
BEGIN
  --l_message := p_sfwr.directory_path || '/' || p_sfwr.actual_file_name || ' (' || p_sfwr.file_size || ')';
  l_file_name :=  p_sfwr.actual_file_name;
  l_file_size := p_sfwr.file_size;
  INSERT INTO file_watcher_output (file_name,file_size_kb,received_date)
  VALUES (l_file_name,l_file_size,sysdate);
  COMMIT;
END;
BEGIN
  DBMS_SCHEDULER.create_job(
    job_name        => 'file_watcher_kpi_job',
    program_name    => 'file_watcher_kpi_prog',
    event_condition => NULL,
    queue_spec      => 'kpi_file_watcher',
    auto_drop       => FALSE,
    enabled         => FALSE);
END;
BEGIN
  DBMS_SCHEDULER.set_attribute('file_watcher_kpi_job','parallel_instances',TRUE);
END;
EXEC DBMS_SCHEDULER.enable('kpi_file_watcher');
EXEC DBMS_SCHEDULER.enable('file_watcher_kpi_prog');
EXEC DBMS_SCHEDULER.enable('file_watcher_kpi_job');Thanks in Advance,

Hi,
I don't have a trigger on my result table to send an email. I checked in dba_scheduler_jobs and run_count is always zero for this job. I used the same script to create another set of jobs and etc with a different name but it is not even working once.
Every 30 secs I am pushing a new file with latest timestamp to the directory. But my result table doesn't get populated. Meaning, I am not seeing a new record in file_watcher_output table.
Thanks,
Jaggyam
