Oracle修改数据文件名/移动数据文件

发布时间：2020-07-12 17:39:04 来源：网络 阅读：1070 作者：hbxztc 栏目：关系型数据库

生产上有时会用到数据文件的迁移，下边示例几种数据文件的迁移方法。

数据库版本

sys@ORCL>select * from v$version;
select * from v$version;

一、关闭数据库修改

   1、使用mv方式(适用于文件系统)

sys@ORCL>shutdown immediate;
shutdown immediate;
Database closed.
Database dismounted.
ORACLE instance shut down.
sys@ORCL>! mv /home/oracle/tt.bdf /home/oracle/tt_mv.dbf
! mv /home/oracle/tt.bdf /home/oracle/tt_mv.dbf
l /home/oracle/tt_! ls -l /home/oracle/tt_mv.dbf
-rw-r----- 1 oracle oinstall 1073750016 Oct 29 08:31 /home/oracle/tt_mv.dbf
sys@ORCL>startup mount;
startup mount;
ORACLE instance started.

sys@ORCL>alter database rename file '/home/oracle/tt.bdf' to '/home/oracle/tt_mv.dbf';
alter database rename file '/home/oracle/tt.bdf' to '/home/oracle/tt_mv.dbf';
Database altered.
sys@ORCL>select name from v$datafile;
select name from v$datafile;
