Morning,

Because you created the LOAD_1 schedule at a time of day when to_char(sysdate,'MI') returned '30'. :-)

I just - at 07:39 created a LOAD_1 schedule and In Toad, extracted the next 10 scheduled run times, they were all at 7:39 and 12:39. This propagates through to the LOAD_MAIN schedule.

Do this to fix it:

dbms_scheduler.create_schedule('LOAD_1', repeat_interval =>

   'FREQ=DAILY;BYHOUR=7,12; BYMINUTE=0'); END; / Add a BYMINUTE to the schedule, or alternatively, use the startdate parameter to set a starting date that include '00' as the minutes. And it's a timestamp not a date, just for added fun. (I hate timestamps, especially those with timezones - as this is!)

HTH Cheers,
Norm.

PS. Yesterday was the first time ever I had to create a schedule (!!!) and I had exactly the same problem you did - the minutes was all over the place until I realised that it reflected the fact that the default start time appears to be systimestamp. So the minutes and seconds part is simply defaulted to the time that the schedule was created. I found that by adding either a startdate or a BYMINUTE, I got it to run on the hour as required - but there's not much I can do about the seconds - unless I use a startdate with zero seconds.
