-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
