Oracle數據庫文件遷移步驟

根據實際須要，有時安裝了oracle以後須要擴展磁盤空間時，每每是新增一個單獨的文件路徑並掛載存儲，這時便須要總體遷移數據庫文件

（1）首先確認須要遷移的數據庫文件

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，備份spfile

SQL> create pfile from spfile;

move SPFILEXSFREE.ORA SPFILEXSFREE.ORA_bak

 

（3）關閉數據庫

SQL> shutdown immediate;

 

（4）遷移數據庫文件

將D:\oracle\oradata下的文件複製到D:\oracle\oradata_bak下（本測試是將oradata目錄下的數據庫文件遷移至oradata_bak下）

 

（5）修改pfile中控制文件路徑

*.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）打開數據庫

SQL> alter database open;

SQL> create spfile from pfile='D:\oracle\product\11.2.0\dbhome_1\database\INITxsfree.ORA';
