Your database is in ARCHIVELOG mode. On Friday evening, you perform an online database backup by using the BACKUP DATABASE command at the Recovery Manager (RMAN) prompt and close the database. On Monday, the System Administrator informs you about the failure of two hard disks. One of the lost disks contains two datafiles, HR1.DBF and HR2.DBF, both of which belong to a read/write tablespace named HR. The disk also contains a datafile, USERS.DBF, which belongs to a read/write tablespace named USERS. You need to restore and recover the database backup that was performed on Friday evening. After mounting the database, you issue the following RMAN commands: RMANRESTORE DATABASE; RMANRECOVER DATABASE; After successfully executing these RMAN commands, you issue the following statement using SQL*Plus: SQLALTER DATABASE OPEN; You receive the following errors when attempting to open the database: ORA-01157: cannot identify/lock data file 10 see DBWR trace file ORA-01110: data file 10: ’D:///USERS.DBF’ What is the cause of these errors?()A、 The USERS.DBF datafile is corrupted and cannot be restored by RMAN.B、 The USERS.DBF datafile was not backed up using the RMAN BACKUP DATABASE command.C、 The USERS.DBF datafile was not restored using the RMAN RESTORE DATABASE command.D、 The USERS.DBF datafile was not recovered using the RMAN RECOVER DATABASE command.
