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.

Subject: dbms_job - running jobs every 15 minutes


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?  :)
