698. In your production database, you:
-Are using Recovery Manager (RMAN) with a recovery catalog to perform the backup operation at regular intervals
-Set the control file autobackup to “on”
-Are maintaining image copi es of the database files
You have lost the server parameter file (SPFILE) and the control file. Which option must you consider
before restoring the SPFILE and the control f ile by using the control file autobackup?
A.Setting DBID for the database
B.Using the RMAN SWITCH command
C.Using the RMAN SRT NEWNAME command
D.Starting up the database instance in the NOMOUNT state
Answer: D
答案解析：在rman 中打开伪实例(nomout)，然后恢复参数文件(restore spfile) 然后退出rman 启动真实实例（nomount) 然后restore controlfile 所以都要nomount 故D正确
