情形： 数据文件要迁移，所以我在open的状态下，物理复制了数据文件，又mount改了数据文件路径。这可好了，不让open了，提示ORA-01194，说system01.dbf需要recover~

以下是我更改路径的SQL脚本：

alter database rename file 'F:\ORACLE\PRODUCT\10.2.0\ORADATA\HISDB\SYSTEM01.DBF' to 'F:\ORACLE\PRODUCT\10.2.0\ORADATA\HISTEST\SYSTEM01.DBF';
alter database rename file 'F:\ORACLE\PRODUCT\10.2.0\ORADATA\HISDB\UNDOTBS01.DBF' to 'F:\ORACLE\PRODUCT\10.2.0\ORADATA\HISTEST\UNDOTBS01.DBF';
alter database rename file 'F:\ORACLE\PRODUCT\10.2.0\ORADATA\HISDB\SYSAUX01.DBF' to 'F:\ORACLE\PRODUCT\10.2.0\ORADATA\HISTEST\SYSAUX01.DBF';
alter database rename file 'F:\ORACLE\PRODUCT\10.2.0\ORADATA\HISDB\USERS01.DBF' to 'F:\ORACLE\PRODUCT\10.2.0\ORADATA\HISTEST\USERS01.DBF';
alter database rename file 'F:\ORACLE\PRODUCT\10.2.0\ORADATA\HISDB\EXAMPLE01.DBF' to 'F:\ORACLE\PRODUCT\10.2.0\ORADATA\HISTEST\EXAMPLE01.DBF';
alter database rename file 'F:\ORACLE\PRODUCT\10.2.0\ORADATA\HISDB\DRSYS' to 'F:\ORACLE\PRODUCT\10.2.0\ORADATA\HISTEST\DRSYS';
alter database rename file 'F:\ORACLE\PRODUCT\10.2.0\ORADATA\HISDB\INDX' to 'F:\ORACLE\PRODUCT\10.2.0\ORADATA\HISTEST\INDX';
alter database rename file 'F:\ORACLE\PRODUCT\10.2.0\ORADATA\HISDB\RBS' to 'F:\ORACLE\PRODUCT\10.2.0\ORADATA\HISTEST\RBS';
alter database rename file 'F:\ORACLE\PRODUCT\10.2.0\ORADATA\HISDB\TOOLS' TO 'F:\ORACLE\PRODUCT\10.2.0\ORADATA\HISTEST\TOOLS'

解决方法：这种情况下，在线日志文件肯定没丢，所以，恢复起来就容易很多了，起因是我刚才先物理复制，之后才shutdown，mount，rename，所以使用修改路径前的redolog进行在线日志解决就行：
