How to create a schedule job in Oracle database?

To schedule a job, first we have to create a schedule, then a program, and then a job.

1. We create a schedule using the following SQL command:

   BEGIN
      DBMS_SCHEDULER.CREATE_SCHEDULE (
      Schedule_name => 'DAILYREPORTJOB',
      Start_date => SYSTIMESTAMP,
      Repeat_interval =>'FREQ=DAILY;BYHOUR=11; BYMINUTE=30',
      Comments => 'DAILY REPORT JOB'
      );
      END;

2. And then we create a program using the following SQL command:

   BEGIN
      DBMS_SCHEDULER.CREATE_PROGRAM (
      program_name => 'DAILYREPORTJOB',
      program_type => 'STORED_PROCEDURE',
      program_action => 'DAILYJOB.REPORTPROC'
      number_of_arguments =>0,
      enabled => TRUE,
      comments => 'DAILY REPORT JOB'
      );
      END;

3. And now create the job :

   BEGIN DBMS_SCHEDULER.CREATE_JOB (
      job_name => 'DAILYREPORTJOB_RUN',
      program_name => 'DAILYREPORTJOB',
      schedule_name => 'DAILYREPORTJOB_SCHED',
      enabled => FLASE,
      comments => 'daily REPORT job'
      );
      END;

4. Finally enable the job:

   EXECUTE DBMS_SCHEDULER.ENABLE('DAILYREPORTJOB_RUN');
