如何将Oracle数据库数据文件迁移到其它目录

一、实验环境

平台：VMware Server 1.0.6 Linux 2.6.18-164 el5

DB Version: Oracle 10g 10.2.0.1

Oracle SID: orcl

数据库运行在归档模式

sys@ORCL> select log_mode from v$database;

LOG_MODE
————
ARCHIVELOG

或者：

sys@ORCL> archive log list
Database log mode Archive Mode
Automatic archival Enabled
Archive destination /u01/arch_orcl
Oldest online log sequence 28
Next log sequence to archive 30
Current log sequence 30

二、操作步骤：

源数据库数据文件位置：

sys@ORCL> select file_name from dba_data_files;

FILE_NAME
—————————————-
/u01/oradata/orcl/system01.dbf
/u01/oradata/orcl/undotbs01.dbf
/u01/oradata/orcl/sysaux01.dbf
/u01/oradata/orcl/users01.dbf

sys@ORCL> select file_name from dba_temp_files;

FILE_NAME
—————————————-
/u01/oradata/orcl/temp01.dbf

sys@select member from v$logfile ;

MEMBER
——————————
/u01/oradata/orcl/redo01.log
/u01/oradata/orcl/redo02.log
/u01/oradata/orcl/redo03.log

需要移动所有的数据文件，采用alter database 方法

1、关闭数据库

sys@ORCL> shutdown immediate
Database closed.
Database dismounted.
ORACLE instance shut down.

2、移动数据文件到/u01/oradata/orcl_test目录

[oracle@ora10gserv orcl]$ pwd
/u01/oradata/orcl
[oracle@ora10gserv orcl]$ mv * /u01/oradata/orcl_test/本文来源gaodai#ma#com搞*!代#%^码$网*
[oracle@ora10gserv orcl]$ ls
[oracle@ora10gserv orcl]$ cd /u01/oradata/orcl_test/
[oracle@ora10gserv orcl_test]$ ls
control01.ctl control03.ctl redo02.log sysaux01.dbf temp01.dbf users01.dbf
control02.ctl redo01.log redo03.log system01.dbf undotbs01.dbf

3、修改控制文件位置

[oracle@ora10gserv /]$ sqlplus /nolog
