You want to migrate your database to ASM, so you have done a clean shutdown, made a closed
backup of the entire You wa database, noted the location of your control files and online redo log files, and
changed your spfile to use OMF. The last step is to run an RMAN script to do the conversion. Using the
following steps, what is the correct order in which the following RMAN commands should be executed?
1. STARTUP NOMOUNT
2. ALTER DATABASE OPEN RESETLOGS
3. SQL "ALTER DATABASE RENAME ,,logfile1 path TO ,,+dgrp4 ,," # plus all other logfiles
4. SWITCH DATABASE TO COPY
5. BACKUP AS COPY DATABASE FORMAT ,,+dgrp4
6. ALTER DATABASE MOUNT
7. RESTORE CONTROLFILE FROM ,,controlfile_location
A. 2, 5, 3, 1, 7, 6, 4
B. 1, 7, 6, 5, 4, 3, 2
C. 5, 1, 2, 7, 4, 6, 3
D. 7, 3, 1, 5, 6, 2, 4

　　After the RMAN script is run and the database is up and running successfully,you may
delete the old database files.

注:OMF,全称是Oracle_Managed Files,即Oracle文件管理
