oracle更改文件,Oracle修改数据文件名以及移动数据文件

發(fā)布時(shí)間：2024/1/23 编程问答 28 豆豆

生活随笔收集整理的這篇文章主要介紹了 oracle更改文件,Oracle修改数据文件名以及移动数据文件小編覺得挺不錯(cuò)的,現(xiàn)在分享給大家,幫大家做個(gè)參考.

生產(chǎn)上有時(shí)會(huì)用到數(shù)據(jù)文件的遷移，下邊示例幾種Oracle數(shù)據(jù)文件的遷移方法。

數(shù)據(jù)庫版本

一、關(guān)閉數(shù)據(jù)庫修改

1、使用mv方式(適用于文件系統(tǒng))

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

sys@ORCL>startup mount;

startup mount;

2、RMAN備份方式(適用于文件系統(tǒng)、祼設(shè)備、ASM)

sys@ORCL>shutdown immediate

Database closed.

Database dismounted.

ORACLE instance shut down.

sys@ORCL>exit

二、在線修改

1、表空間OFFLINE方式

sys@ORCL>col file_name for a70

sys@ORCL>select file_name,tablespace_name,status,online_status from dba_data_files;

select file_name,tablespace_name,status,online_status from dba_data_files;
