DBMS_JOB

Oracle 9.2

We want to schedule a job via DBMS_JOB to run at 12:30am and 12:30pm. I'd prefer to schedule 1 job to do this rather than 1 job to run at 12:30am and 1 job at 12:30pm (I don't want them to run on top of each other).

When I schedule the job via this command:

execute dbms_job.submit(job=3D>:jobno, what=3D>'program_name;', next_date=3D>trunc(sysdate+1)+1/48,
interval=3D>'trunc(SYSDATE+12/24,''HH'')');

It works as expected. But the problem I have is if the job gets broken or the db is down the next time it executes it will schedule itself 12 hours in the future- if it happens to run at 2:10am then the next run would be 2:00pm. Is there a way with 1 job to force it to only run at 12:30am and 12:30pm regardless of the time of current execution?

Thanks
