Oracle控制文件日志文件数据文件迁移

Posted 2020-10-10

1.查看表空间对应关系

d:

cd D:\app\administrator\product\11.2.0\dbhome_1\BIN

sqlplus sys/[email protected] as sysdba

select * from v$tablespace;

 

2.关闭数据库

shutdown immediate;

 

3.复制数据文件到新的位置

 

4.启动数据库到mount状态

startup mount;

5.重命名数据文件

alter database rename file ‘H:\oradata\spectra\RISDAT01.DBF‘ to ‘L:\oradata\spectra\RISDAT01.DBF‘;

alter database rename file ‘H:\oradata\spectra\RISDAT02.DBF‘ to ‘L:\oradata\spectra\RISDAT02.DBF‘;

alter database rename file ‘H:\oradata\spectra\SPDAT01.DBF‘ to ‘L:\oradata\spectra\SPDAT01.DBF‘;

alter database rename file ‘H:\oradata\spectra\SPDAT02.DBF‘ to ‘L:\oradata\spectra\SPDAT02.DBF‘;

alter database rename file ‘H:\oradata\spectra\SPIDX01.DBF‘ to ‘L:\oradata\spectra\SPIDX01.DBF‘;

alter database rename file ‘H:\oradata\spectra\SPIDX02.DBF‘ to ‘L:\oradata\spectra\SPIDX02.DBF‘;

alter database rename file ‘H:\oradata\spectra\SYSAUX01.DBF‘ to ‘L:\oradata\spectra\SYSAUX01.DBF‘;

alter database rename file ‘H:\oradata\spectra\SYSTEM01.DBF‘ to ‘L:\oradata\spectra\SYSTEM01.DBF‘;

alter database rename file ‘H:\oradata\spectra\TEMP01.DBF‘ to ‘L:\oradata\spectra\TEMP01.DBF‘;

alter database rename file ‘H:\oradata\spectra\UNDOTBS01.DBF‘ to ‘L:\oradata\spectra\UNDOTBS01.DBF‘;

alter database rename file ‘H:\oradata\spectra\USERS01.DBF‘ to ‘L:\oradata\spectra\USERS01.DBF‘;

 

 

5.重命名日志文件

alter database rename file ‘H:\oradata\spectra\REDO01.LOG‘ to ‘L:\oradata\spectra\REDO01.LOG‘;

alter database rename file ‘H:\oradata\spectra\REDO02.LOG‘ to ‘L:\oradata\spectra\REDO02.LOG‘;

alter database rename file ‘H:\oradata\spectra\REDO03.LOG‘ to ‘L:\oradata\spectra\REDO03.LOG‘;

6.打开数据库并查看状态

alter database open;

shutdown immediate;

startup;

select * from v$logfile;

或

select a.group#, a.status, b.member,a.bytes/1024/1024 sizeM from v$log a ,v$logfile b where a.group#=b.group#;

alter system switch logfile;//切换日志

 

===========================================================

7.查看控制文件

select name from v$controlfile;

 

8.恢复控制文件

shutdown immediate;

startup nomount;

quit

rmant target /

restore controlfile to ‘L:\oradata\spectra\CONTROL01.CTL‘ from ‘H:\oradata\spectra\CONTROL01.CTL‘ ;

restore controlfile to ‘L:\oradata\spectra\CONTROL02.CTL‘ from ‘H:\oradata\spectra\CONTROL02.CTL‘ ;

restore controlfile to ‘L:\oradata\spectra\CONTROL03.CTL‘ from ‘H:\oradata\spectra\CONTROL03.CTL‘ ;

 

quit //退出rman

 

9..修改控制文件位置

sqlplus / as sysdba

alter system set control_files=‘L:\oradata\spectra\CONTROL01.CTL‘,‘L:\oradata\spectra\CONTROL02.CTL‘,‘L:\oradata\spectra\CONTROL03.CTL‘  scope=spfile;

 

10.启动数据库

startup mount force;

select * from v$controlfile;

alter database open;

select * from spectra.version;

 

 

11.查看数据库以上更改的信息 select name from v$controlfile;

select * from v$logfile;

select * from v$tablespace;
