1、环境介绍：
这是一测试库，我将参数文件，控制文件，数据文件全部删除之后，做数据恢复，但是
我把控制文件和参数文件都恢复回来了，可数据库却怎么也打不开，报ORA-01103: database name 'WWL' in control file is not 'DUMMY'错误
我的数据库名称是:WWL
2、执行过程：
恢复参数文件：
RMAN> setDBID=5520179
executing command: SET DBID
RMAN> restorespfile from autobackup;
Starting restore at 23-MAY-12
using target database control file insteadof recovery catalog

RMAN>
3、恢复控制文件
RMAN> restorecontrolfile from autobackup;
Starting restore at 23-MAY-12
using channel ORA_DISK_1

我们刚才做了参数文件和控制文件的恢复，要不将数据库重启下，，看有没有问题。

这个问题我一兄弟在AIX，Linux，Windows 上分别做实验了，结果是在Windows下不用重启数据库，Rman就可以认到，而不会是DUMMY数据库。
B，每小时执行一次，整点执行
interval => 'trunc(sysdate,'HH')+1/24'
C，一个小时后执行
interval => 'sysdate+1/24'
