BEGIN
  DBMS_SCHEDULER.CREATE_JOB (
   job_name         =>  ‘my_lightweight_job1‘,
   program_name     =>  ‘polling_prog_n2‘,
   repeat_interval  =>  ‘FREQ=SECONDLY;INTERVAL=10‘,
   end_date         =>  ‘30-APR-09 04.00.00 AM Australia/Sydney‘,
   job_style        => ‘LIGHTWEIGHT‘,
   comments         => ‘Job that polls device n2 every 10 seconds‘);
END;
