根据实际需要，有时安装了oracle之后需要扩展磁盘空间时，往往是新增一个单独的文件路径并挂载存储，这时便需要整体迁移数据库文件
（1）首先确认需要迁移的数据库文件
SQL> select name from v$controlfile;
NAME
-----------------------------------------
D:\ORACLE\ORADATA\XSFREE\CONTROL01.CTL
D:\ORACLE\ORADATA\XSFREE\CONTROL02.CTL
SQL> select name from v$datafile;
NAME
-----------------------------------------
D:\ORACLE\ORADATA\XSFREE\SYSTEM01.DBF
D:\ORACLE\ORADATA\XSFREE\SYSAUX01.DBF
D:\ORACLE\ORADATA\XSFREE\UNDOTBS01.DBF
D:\ORACLE\ORADATA\XSFREE\USERS01.DBF
SQL> select member from v$logfile;
MEMBER
---------------------------------------------
D:\ORACLE\ORADATA\XSFREE\REDO01.LOG
D:\ORACLE\ORADATA\XSFREE\REDO02.LOG
D:\ORACLE\ORADATA\XSFREE\REDO03.LOG
SQL> select name from v$tempfile;
NAME
--------------------------------------
D:\ORACLE\ORADATA\XSFREE\TEMP01.DBF
（2）创建pfile，备份spfile
SQL> create pfile from spfile;
move SPFILEXSFREE.ORA SPFILEXSFREE.ORA_bak
（3）关闭数据库
SQL> shutdown immediate;
（4）迁移数据库文件
将D:\oracle\oradata下的文件复制到D:\oracle\oradata_bak下（本测试是将oradata目录下的数据库文件迁移至oradata_bak下）
（5）修改pfile中控制文件路径
*.control_files='D:\oracle\oradata_bak\xsfree\control01.ctl','D:\oracle\oradata_bak\xsfree\control02.ctl'
（6）rename文件
SQL> startup mount pfile='D:\oracle\product\11.2.0\dbhome_1\database\INITxsfree.ORA';
SQL> alter database rename file 'D:\ORACLE\ORADATA\XSFREE\SYSTEM01.DBF' to 'D:\ORACLE\ORADATA_BAK\XSFREE\SYSTEM01.DBF';
SQL> alter database rename file 'D:\ORACLE\ORADATA\XSFREE\SYSAUX01.DBF' to 'D:\ORACLE\ORADATA_BAK\XSFREE\SYSAUX01.DBF';
SQL> alter database rename file 'D:\ORACLE\ORADATA\XSFREE\UNDOTBS01.DBF' to 'D:\ORACLE\ORADATA_BAK\XSFREE\UNDOTBS01.DBF';
SQL> alter database rename file 'D:\ORACLE\ORADATA\XSFREE\USERS01.DBF' to 'D:\ORACLE\ORADATA_BAK\XSFREE\USERS01.DBF';
SQL> alter database rename file 'D:\ORACLE\ORADATA\XSFREE\REDO01.LOG' to 'D:\ORACLE\ORADATA_BAK\XSFREE\REDO01.LOG';
SQL> alter database rename file 'D:\ORACLE\ORADATA\XSFREE\REDO02.LOG' to 'D:\ORACLE\ORADATA_BAK\XSFREE\REDO02.LOG';
SQL> alter database rename file 'D:\ORACLE\ORADATA\XSFREE\REDO03.LOG' to 'D:\ORACLE\ORADATA_BAK\XSFREE\REDO03.LOG';
SQL> alter database rename file 'D:\ORACLE\ORADATA\XSFREE\TEMP01.DBF' to 'D:\ORACLE\ORADATA_BAK\XSFREE\TEMP01.DBF';
（7）打开数据库
SQL> alter database open;
SQL> create spfile from pfile='D:\oracle\product\11.2.0\dbhome_1\database\INITxsfree.ORA';
