Here is a query that you can run on the BODI repository to fetch the job schedule details.

Select upper (al_lang.NAME) as jobname,
upper (al_sched_info.sched_name) as schedule_name,
al_sched_info.start_time as start_time,
al_sched_info.host_name host_server
from di_edw.al_lang al_lang full outer join di_edw.al_sched_info al_sched_info on al_lang.guid = al_sched_info.job_guid
where active = 1
and al_lang.object_type = 0
and TYPE = 0
and al_lang.object_key =
(SELECT MAX (object_key)
FROM di_edw.al_lang l
WHERE l.NAME = al_lang.NAME AND l.object_type = 0 AND l.TYPE = 0)
ORDER BY 1, 2
