转移oracle数据文件"*.dbf"
转移过程:
1.先登录sqlplus:
C:/Documents and Settings/jbdu>sqlplus “/as sysdba”
2.修改表空间为Offline: www.2cto.com
SQL> alter tablespace users offline;
3.拷贝表空间文件
拷贝
D:/oracle/product/10.2.0/oradata/orclado/USERS01.DBF 到
H:/oracle/product/10.2.0/oradata/orclado/USERS01.DBF
4.修改oracle表空间指向地址
SQL> alter database rename file ‘D:/oracle/product/10.2.0/oradata/orclado/USERS01.DBF'to 'H:/oracle/product/10.2.0/oradata/orclado/USERS01.DBF';
5.修改表空间为Online
SQL> alter tablespace users online;
具体如下:
1、查看表空间:
select tablespace_name from dba_tablespaces;
获知表空间的名称。
2、只有部分表空间能按照此方式转移,system、temp、sysaux等表空间按照第3种方式进行转移。
alter tablespace users offline;
alter tablespace EXAMPLE offline;
alter tablespace CMD_TS offline;
alter database rename file 'D:/ORACLE/PRODUCT/10.2.0/ORADATA/orcl/EXAMPLE01.DBF' to 'H:/ORACLE/PRODUCT/10.2.0/ORADATA/ORCL/EXAMPLE01.DBF'; www.2cto.com
alter database rename file 'D:/ORACLE/PRODUCT/10.2.0/ORADATA/orcl/USERS01.DBF' to 'H:/ORACLE/PRODUCT/10.2.0/ORADATA/ORCL/USERS01.DBF';
alter tablespace users online;
alter tablespace EXAMPLE online;
alter tablespace CMD_TS online;
3.对于system、temp、undotbs1、sysaux等表空间,先关闭
数据库,然后启动到mount状态,再修改数据文件名称。
shutdown immediate;
startup mount;
alter database rename file 'D:/ORACLE/PRODUCT/10.2.0/ORADATA/orcl/SYSAUX01.DBF' to 'H:/ORACLE/PRODUCT/10.2.0/ORADATA/ORCL/SYSAUX01.DBF';
alter database rename file 'D:/ORACLE/PRODUCT/10.2.0/ORADATA/orcl/SYSTEM01.DBF' to 'H:/ORACLE/PRODUCT/10.2.0/ORADATA/ORCL/SYSTEM01.DBF';
alter database rename file 'D:/ORACLE/PRODUCT/10.2.0/ORADATA/orcl/TEMP01.DBF' to 'H:/ORACLE/PRODUCT/10.2.0/ORADATA/ORCL/TEMP01.DBF';
alter database rename file 'D:/ORACLE/PRODUCT/10.2.0/ORADATA/orcl/UNDOTBS01.DBF' to 'H:/ORACLE/PRODUCT/10.2.0/ORADATA/ORCL/UNDOTBS01.DBF';
注意如果报错出现 www.2cto.com
ora-01113
ora-01110
就执行
recover datafile 'H:/ORACLE/PRODUCT/10.2./ORADATA/ORCL/UNDOTBS01.DBF';
alter database open;
再执行
SQL> alter tablespace users/example/... online;
www.2cto.com
%alter tablespace SYSTEM offline;
%alter tablespace UNDOTBS1 offline;
%alter tablespace SYSAUX offline;
%alter tablespace TEMP offline;
alter tablespace SYSTEM online;
alter tablespace UNDOTBS1 online;
alter tablespace SYSAUX online;
alter tablespace TEMP online;
4.查询数据文件名称:
select file_name from sys.dba_data_files;
