oracle11g移动数据库文件

[root@localhost ~]# su - oracle
[oracle@localhost ~]$ lsnrctl start
SQL> conn /as sysdba
Connected to an idle instance.

SQL> select file_name from sys.dba_data_files;

FILE_NAME
--------------------------------------------------------------------------------
/u01/app/oracle/oradata/yuchunju/users01.dbf
/u01/app/oracle/oradata/yuchunju/undotbs01.dbf
/u01/app/oracle/oradata/yuchunju/sysaux01.dbf
/u01/app/oracle/oradata/yuchunju/system01.dbf
/u01/app/oracle/oradata/yuchunju/example01.dbf

[root@localhost yuchunju]# cp users01.dbf test.dbf   //以防万一
[root@localhost yuchunju]# mkdir /u01/data
[root@localhost yuchunju]# mv users01.dbf /u01/data/

SQL> conn /as sysdba
Connected to an idle instance.
SQL> startup mount

/u01/app/oracle/oradata/yuchunju/example01.dbf

数据库文件移动成功。

再测试一个

/u01/app/oracle/oradata/yuchunju/sysaux01.dbf

[root@localhost data]# mkdir /u02/data
[root@localhost data]# chown -R oracle:oinstall /u02
首先要关闭数据库
SQL> shutdown immediate
然后移动数据文件
[root@localhost data]# mv /u01/app/oracle/oradata/yuchunju/sysaux01.dbf /u02/data/

等待数据库装载
SQL> startup mount 

通过alter语句，修改文件路径和名称。完成后打开数据库
SQL>alter database rename file '/u01/app/oracle/oradata/yuchunju/sysaux01.dbf' to '/u02/data/sysaux01.dbf';
打开数据库
SQL>alter database open;

SQL> select file_name from sys.dba_data_files;
