【Oracle】重命名数据文件

1）查看当前数据文件位置

SQL> select file_id,file_name,tablespace_name from dba_data_files;

FILE_ID FILE_NAME                                          TABLESPACE_NAME
---------- -------------------------------------------------- ------------------------------
         4 /u01/app/oracle/oradata/drz/users01.dbf            USERS
         3 /u01/app/oracle/oradata/drz/undotbs01.dbf          UNDOTBS1
         2 /u01/app/oracle/oradata/drz/sysaux01.dbf           SYSAUX
         1 /u01/app/oracle/oradata/drz/system01.dbf           SYSTEM

5 /u01/app/oracle/oradata/drz/example01.dbf          EXAMPLE

2）一致性关闭数据库

SQL> shutdown immediate
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> 
SQL> 
SQL> exit                                                                                  
Disconnected from Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options

3）操作系统中修改数据文件的名称

[oracle@lgr ~]$ mv /u01/app/oracle/oradata/drz/users01.dbf /u01/app/oracle/oradata/drz/users01a.dbf

4）启动数据库到mount状态

[oracle@lgr ~]$ sqlplus / as sysdba

5）数据库中修改数据文件的名称，并打开数据库

SQL> alter database rename file '/u01/app/oracle/oradata/drz/users01.dbf' to '/u01/app/oracle/oradata/drz/users01a.dbf';

Database altered.

6）验证修改后的结果

SQL> select file_id,file_name,tablespace_name from dba_data_files;

FILE_ID FILE_NAME                                          TABLESPACE_NAME
---------- -------------------------------------------------- ------------------------------
         4 /u01/app/oracle/oradata/drz/users01a.dbf            USERS
         3 /u01/app/oracle/oradata/drz/undotbs01.dbf          UNDOTBS1
         2 /u01/app/oracle/oradata/drz/sysaux01.dbf           SYSAUX
         1 /u01/app/oracle/oradata/drz/system01.dbf           SYSTEM
         5 /u01/app/oracle/oradata/drz/example01.dbf          EXAMPLE
