This example shows you how to create a job in Oracle to run every hour using the DBMS_SCHEDULER package.

1. Create a Job Using DBMS_SCHEDULER.CREATE_JOB

The following PL/SQL code will schedule a job that will start on 20th October 2019 at 1:00 AM India time to run every hour on every day. You can remove the Day Name from the repeat interval parameter to exclude a particular day. The job type is stored procedure and will run the procedure specified in the Job action parameter.

BEGIN
  DBMS_SCHEDULER.CREATE_JOB (
   job_name           =>  'HOURLY_JOB',
   job_type           =>  'STORED_PROCEDURE',
   job_action         =>  'YOUR_SCHEMA.YOUR_PROCEDURE',
   start_date         =>  '20-OCT-19 01.00.00 AM Asia/Kolkata',
   repeat_interval    =>  'FREQ=HOURLY;BYDAY=MON,TUE,WED,THU,FRI,SAT,SUN', 
   end_date           =>  NULL,
   auto_drop          =>   FALSE,
   job_class          =>  'SYS.DEFAULT_JOB_CLASS',
   comments           =>  'run job every hour');
END;
/

2. Enable the Job

BEGIN 
    DBMS_SCHEDULER.enable('HOURLY_JOB'); 
END;
/

Your hourly DBMS_SCHEDULER job is created and enabled now. You can change the time zone from "Asia/Kolkata" to any country time zone by getting the value from the following query:

SELECT DISTINCT tzname, TZ_OFFSET (tzname)
 FROM V$TIMEZONE_NAMES
ORDER BY tzname;
