迁移控制文件方法（二）

 Oracle数据库文件迁移步骤 
 
（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，open和后面的创建spfile 无顺序性 先执行哪个都可
SQL> alter database open;
SQL> create spfile from pfile='D:\oracle\product\11.2.0\dbhome_1\database\INITxsfree.ORA';
create pfile='e:\b.txt' from spfile;  --验证新spfile内容已经修改


(8) 使用新spfile重启库
shutdown immediate 
startup
