DBMS_SCHEDULER.create_job parameter for repeat_interval

Question

how to specify the DBMS_SCHEDULER.create_job repeat_interval parameter for 15 mintues?

Answer 1

You probably want an interval like this:
FREQ=MONTHLY;BYMONTHDAY=2;BYHOUR=20;BYMINUTE=0;BYSECOND=0;You can use the DBMS_SCHEDULER.EVALUATE_CALENDAR_STRING function to test it, like so:
SQL > DECLARE
  2  start_date        TIMESTAMP;
  3  return_date_after TIMESTAMP;
  4  next_run_date     TIMESTAMP;
  5  BEGIN
  6  start_date :=
  7    to_timestamp_tz('01-JAN-2003 10:00:00','DD-MON-YYYY HH24:MI:SS');
  8  return_date_after := start_date;
  9  FOR i IN 1..5 LOOP
10    DBMS_SCHEDULER.EVALUATE_CALENDAR_STRING(
11      'FREQ=MONTHLY;BYMONTHDAY=2;BYHOUR=20;BYMINUTE=0;BYSECOND=0;',
12      start_date, return_date_after, next_run_date);
13  DBMS_OUTPUT.PUT_LINE('next_run_date: ' || next_run_date);
14  return_date_after := next_run_date;
15  END LOOP;
16  END;
17  /
next_run_date: 01/02/2003 08:00:00.000000 PM
next_run_date: 02/02/2003 08:00:00.000000 PM
next_run_date: 03/02/2003 08:00:00.000000 PM
next_run_date: 04/02/2003 08:00:00.000000 PM
next_run_date: 05/02/2003 08:00:00.000000 PM
