View the Exhibit to examine the error during the database startup. You open an RMAN session for the database instance. To repair the failure, you executed the following as the first command in the RMAN session:
RMAN> REPAIR FAILURE;
Which statement describes the consequence of the command?
Exhibit:

A.The command performs the recovery and closes the failures.
B.The command executes the RMAN script to repair the failure and removes the entry from the Automatic Diagnostic Repository (ADR).
C.The command only displays the advice and the RMAN script required for repair.
D.The command produces an error because the ADVISE FAILURE command has not been executed before the REPAIR FAILURE command.

　

　　此题考点是使用故障恢复指导进行恢复（Data Recovery Advisor）。故障记录存储在 ADR 目录中，可以手动的进行自动恢复。 ADVISE FAILURE 显示恢复的脚本。 REPAIR FAILURE，执行之前的脚本。
顺序如下：
list failure--advise failure--repair failure
在运行 repair failure 之前必须使用 advise failure 否则会报错
