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: 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
RMAN>
4、报错信息：

注意：问题是我恢复的控制文件没有错呀，在本机器上也没有部署过DUMMY的数据库呀，只有一个实例是WWL。
查询实例信息，实例信息显示没有错呀是WWL。
SQL> selectinstance_name,status from v$instance;
INSTANCE_NAME STATUS

WWL STARTED
SQL> alterdatabase mount; ----顺便执行了下mount database;
alter database mount

ERROR at line 1:
ORA-01103: database name 'WWL' in controlfile is not 'DUMMY'
奇怪的事发生了，现在再次登录到RMAM居然连接到的是DUMMY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。
