RE: dbms_job - running jobs every 15 minutes

How about

dbms_job.submit(:jobno, 'statspack.snap', sysdate+n/1440, 'sysdate 15/1440');

where n= a number of minutes to the nearest 15 minutes. So if it's 14:25 then it would
be sysdate+5/1440.

since you only need to do this one time, just make sure that sysdate + n = 0, 15, 30 or 45
after the hour... :-) Of course, if you want to automate the thing, then build this around a PL/SQL procedure...that calculates the value of n..... Not elegant, but I think that when
someone looks at DBA_JOBS they are not going to ask what the $*#(@( you were trying to do..
I subscribe to the KISS philosophy...

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? :)
