（685）In your test database:

-You are using Recovery Manager（RMAN）to perform incremental backups of your test database，

-The test database is running in NOARCHIVELOG mode，

-One of the data files is corrupted，

-All online redo log files are lost because of a media failure

Which option must you consider in this scenario?

A. Configuring the database in ARCHVIELOG mode and then using incremental backup to recover the database

B. Using incremental backup to recover the damaged data file and then manually creating the online redo log files

C. Creating a new test database because the database is not recoverable due to the fact that the database is configured in NOARCHIVELOG mode

D. Using incremental backups to recover the database by using the RECOVER DATABASE NOREDO command and then using the RESETLOGS option to open the database.

答案：（D）

解析：

（Oracle的非归档模式也可以支持增量备份，如果某个数据文件损坏，即使所有的redolog也坏了，跟恢复没有任何关系，

因为非归档模式的恢复只能恢复到以前备份的那一点，是无法用到redolog的。
