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; 作者 zhywjw |
