Q

题目

Where is an expdp operation tracked?

A. dump files

B. control file

C. log files

D. Automatic Diagnostic Repository(ADR)

E. master table (MT)

A

答案

Answer：E

题目中的tracked的意思是跟踪。在数据泵运行过程中，主表(Master Table简称MT)起到了关键性作用，在MT表中，保存了整个数据泵运行过程中的相关信息，这些信息包括要处理的所有对象的信息，当前正在处理的对象信息.在启动数据泵的时候，如果我们制定了任务名称，则MT表名称就等于任务名称。
