Oracle 11G OCP 1Z0-053 32

（32）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 copies of the database files

-You have lost the server parameter tile(SPFILE)and the control file.

Which option must you consider before restoring the SPFILE and the control file by using the control file autobackup?

A. setting DBID for the database

B. using the RMAN SWITCH command

C. using the RMAN SWITCH command

D. starting up the database Instance In the NOMOUNT state

答案：（A）

解析:

（對於CATALOG方式，SPFILE的恢復相對簡單很多。不過Oracle文件上對於SPFILE的恢復的描述有些小問題：SET DBID這個步驟是不能省略的，否則會報錯。
