Schedule Executed weekly except for a specific day of the month

Question

Hi all,
I need to create a schedule that run weekly every sunday at 9 PM, except for 2nd day of the month it will run at 7 AM.
I have created 2 schedules:
1. One to run weekly every sunday at 9 PM, but i don't know from where i can specify the days of the month the schedule will be inactive on it.
* I have tried By Month Day option, and choose all days of the month except second day of the month to run on it.
FREQ=WEEKLY; BYMONTHDAY=1,3,4,5,..,31; BYDAY= SUN; BYHOUR=21;
But, on the schedule preview window as i have designed the schedule from oracle warehouse builder, shows sunday, 02, July for example.
as an execution date for this schedule.
which is not appropriate.
2. Another job is created to run monthly on the 2nd day of the month,
FREQ=MONTHLY; BYMONTHDAY=2; BYDAY= SUN; BYHOUR=7;
So, please advice how to create schedules daily or weekly and neglect some days of month from it.

Answer 1

Hi,
You can use the exclude clause introduced in 10gR2 for this by creating a schedule when your job should not run and excluding it. An example is given below.
Hope this helps,

create or replace procedure print_schedule_dates
   schedule in varchar2,
   start_date in timestamp with time zone default dbms_scheduler.stime(),
   number_of_dates in pls_integer default 10
is
  date_after timestamp with time zone := start_date - interval '1' second;
  next_date timestamp with time zone;
begin
  for i in 1 .. number_of_dates
  loop
    dbms_scheduler.evaluate_calendar_string
     (schedule, start_date, date_after, next_date);
    dbms_output.put_line(to_char(next_date,
                    'DY DD-MON-YYYY (DDD-IW) HH24:MI:SS TZH:TZM TZR'));
    date_after := next_date;
  end loop;
end;
begin
  dbms_scheduler.create_schedule('monthday2',
    repeat_interval=>'freq=monthly;bymonthday=2');
end;
exec print_schedule_dates('FREQ=WEEKLY;BYDAY=SUN;BYHOUR=21;exclude=monthday2',sysdate+1,30);
exec print_schedule_dates('FREQ=WEEKLY;BYDAY=SUN;BYHOUR=21',sysdate+1,30);
