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
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
allocated channel: ora_disk_1
channel ora_disk_1: sid=39 devtype=disk
channel ora_disk_1: looking for autobackupon day: 20120523
channel ora_disk_1: autobackup found:c-5520179-20120523-04
channel ora_disk_1: spfile restore fromautobackup complete
finished restore at 23-may-12
rman>
3、恢复控制文件
rman> restorecontrolfile from autobackup;
starting restore at 23-may-12
using channel ora_disk_1
channel ora_disk_1: looking for autobackupon day: 20120523
channel ora_disk_1: autobackup found:c-5520179-20120523-04
channel ora_disk_1: control file restorefrom autobackup complete
output filename=/dbsoft/product/10.2.0/db_1/dbs/cntrlwwl.dbf
finished restore at 23-may-12

库：
问题是，我确定没有这个库呀，怎么办。。。

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。
sql> shutdownimmediate

再次登录正常。

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'
