Oracle数据库文件迁移步骤

根据实际须要，有时安装了oracle以后须要扩展磁盘空间时，每每是新增一个单独的文件路径并挂载存储，这时便须要总体迁移数据库文件

（1）首先确认须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）建立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';
