5）启动数据库到mount状态并使用11g数据库的新特性（list/advise/repair failure）
RMAN> startup mount;

database is already started
database mounted
released channel: ORA_DISK_1
released channel: ORA_DISK_2
released channel: ORA_DISK_3
released channel: ORA_DISK_4

新特性：
list failure;
--如果list failure 没有输出结果，则需要我们手动恢复数据库；
advise failure;
--如果advise failure 输出的最后，显示没有可用的自动修复选项，则同样需要我们手动恢复；
repair failure;
--三条命令顺序不能改变

补充：
如果list failure没有输出结果，
则可以尝试打开数据库，查看报错信息，然后进行相应的处理；
eg：
alter database open;
alter database open resetlogs;
restore datafile 1;
list failure;
advise failure;
repair failure;

指令：
RMAN>list failure;

RMAN>advise failure;

RMAN>repair failure;

具体执行过程：
RMAN> list failure;
