上面我只是简单的举了个移动数据文件的例子，如果你想改名或者操作其他数据文件，操作步骤如法炮制就可以了。

SQL> show parameter db_create_file_dest

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
db_create_file_dest                  string      d:/oracle/db_create_file_dest

 

还可以注意到一点的是，当我进行了如上操作以后，路径D:/ORACLE/DB_CREATE_FILE_DEST/ORCL/DATAFILE/下的数据文件已经自动消失了（当时我是复制，不是剪切），估计由于是OMF功能，ORACLE自动给删除了吧。
