Oracle OCP IZ0-053 Q449(Scheduler Window&Resource Plan&Schedule Object)
449.Which of the following objects can be directly referenced by a window object? (Choose all that apply.)
A. Schedule object
B. Program object
C. Job object
D. Resource plan
E. Resource consumer group
Answer: AD
Window是Oracle数据库用来管理schedule jobs的一个工具，可以通过resource plan控制分配给作业的资源的多少
参考：
Windows define the times when resource plans are active. Since job classes point to resource consumer groups, and therefore resource plans, this mechanism allows control over the resources allocated to job classes and their associated jobs during specific time periods. A window can be assigned to the schedule_name parameter of a job instead of a schedule object.

可以从创建window的过程参数看出，window是可以引用resource plna与schedule object的
BEGIN
dbms_scheduler.create_window(window_name =>,
resource_plan =>,
schedule_name =>,
duration =>,
window_priority =>,
comments =>);
END;
