Hi,
You can define an interval as follows:
SQL> alter session set nls_date_format='dd-mm-yyyy hh24:mi:ss';
Session altered.
SQL> select add_months(trunc(sysdate, 'mm'), 1) from dual;
ADD_MONTHS(TRUNC(SY
01-09-2009 00:00:00
1 row selected.
SQL> select add_months(trunc(sysdate, 'mm'), 1) + 7/24 from dual;
ADD_MONTHS(TRUNC(SY
01-09-2009 07:00:00So, if you want your job to start at 07.00 every month you submit:
declare
nextdate date;
begin
SELECT trunc(add_months(sysdate,1),'MM') into nextdate FROM DUAL ;
dbms_output.put_line(nextdate);
dbms_job.submit(
what=>'begin someprocedure; end;',
next_date=>sysdate,
interval=>'add_months(trunc(sysdate, ''mm''), 1) + 7/24');
end; untested
