Oracle object: Window

A window is a scheduler object.
A window defines a period of time during which jobs can automatically be started.
A window associates a resource plan with a recurring time window.
At most one window is open at a given point in time: 
select
   value
from
   dba_scheduler_global_attribute
where
   attribute_name = 'CURRENT_OPEN_WINDOW'
;
Because windows' time spans might overlap, a window can be given a priority.
