54題、choose two
Which two statements describe the relationship between a scheduler window, a resource manager plan, and a job class?
A) A scheduler window specifies a job class that will be activated when that scheduler window becomes active.
B) A scheduler window together with a job class, controls resource allocation for a job using that job class in that scheduler window
C) A job class specifies a scheduler window that will be open when that job class becomes active.
D) A scheduler window can control resource allocation by itself.
E) A scheduler window specifies a resource manager plan that will be activated when that scheduler window becomes active.
Answer：BE
(解析：Job Classes 相當于創建了一個job 組，DBA 可以將那些具有相同特性的job，統統放到相同的Job Classes中，然后通過對Job Class 應用ORACLE 中的"資源使用計劃"特性，就可以對這些job 執行過程中所需要的資源分配情況進行管理。)
