The loss of which two types of files may require a recovery with

the RESETLOGS option?(Choose two.)

A. control files

B. password file

C. archived log files

D. system-critical data files for which all the redo entries are

present

E. non-system-critical data files for which all the redo entries

are present

Answer: A, C

几点总结:(eygle:)

1:只要拥有当前日志文件,就可以执行完全恢复,是否需要 resetlogs 方式打开,

取决是否使用备份的控制文件。

2:如果日志文件没有损失,可以通过重建控制文件的方法来完成完全恢复,这种

情况下,不再需要通过 resetlogs 方式打开数据库。
