RMAN> restore controlfile from autobackup;
Starting restore at 03-APR-16
using channel ORA_DISK_1
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of restore command at 04/03/2016 15:09:54
RMAN-06496: must use the TO clause when the database is mounted or open
恢复控制文件在要在nomount状态下恢复的，所以说这个不是一个正确的解决方法。
