No, as written, my jobs start on every quarter hour, regardless of
runtime.
e.g. 09:00, 09:15, 09:30, 09:45 ...

Subject: Re:RE: dbms_job - running jobs every 15 minutes
One potential problem with DBMS_JOBS as is being discussed here is that
Oracle
computes the next_date at the end of the job. They do that so that if a
job
runs longer than it's schedule interval the two invocations will not run
into
each other. Now as discussed, if the job is scheduled to start at 9:00 AM
and
runbs for 5 minutes it's next_date for run #2 will be 9:20, not 9:15, and
it
will creep 5 minutes every time.

Feeling particularly anal the other day, I used the following
specification to
run statspack at the top of the hour, 15, 30 and 45 minutes after the
hour.
variable jobno number;
variable instno number;
begin
select instance_number into :instno from v$instance;
dbms_job.submit(
:jobno
, 'statspack.snap;'
-- every 15 minutes at 00,15,30 and 45
, trunc(sysdate,'hh24') + ( ( 15 + ( 15 *
floor(to_number(to_char(sysdate,'mi')) / 15))) / ( 24 * 60 ))
, 'trunc(sysdate,''hh24'') + ( ( 15 + ( 15 *
floor(to_number(to_char(sysdate,''mi'')) / 15))) / ( 24 * 60 ))'
);
commit;
end;
/
Seems to me that the time specs could be simplified a bit.
Anyone care to give it a go? :)
