oracle修改数据文件路径

方法1.关机修改数据文件路径

1.查看当前数据文件路径
SQL> select file_name from dba_data_files;

FILE_NAME
--------------------------------------------------------------------------------
/u01/app/oracle/oradata/oradb/users01.dbf
/u01/app/oracle/oradata/oradb/undotbs01.dbf
/u01/app/oracle/oradata/oradb/sysaux01.dbf
/u01/app/oracle/oradata/oradb/system01.dbf
/u01/app/oracle/oradata/gen_cfg01.dbf
/u01/app/oracle/oradata/gen_ers01.dbf
/u01/app/oracle/oradata/gen_etl01.dbf
/u01/app/oracle/oradata/gen_ods01.dbf
/u01/app/oracle/oradata/gen_log01.dbf
/u01/app/oracle/oradata/gen_rps01.dbf
/u01/app/oracle/oradata/gen_ctiadaptor01.dbf
/u01/app/oracle/oradata/gen_cdr.dbf

12 rows selected.

2.停库
SQL> shutdown immediate
Database closed.
Database dismounted.
ORACLE instance shut down.

3.移动数据文件到新路径下
[oracle@node1 ~]$ cd /u01/app/oracle/oradata/
[oracle@node1 oradata]$ ls
gen_cdr.dbf    gen_ctiadaptor01.dbf  gen_etl01.dbf  gen_ods01.dbf  oradb
gen_cfg01.dbf  gen_ers01.dbf         gen_log01.dbf  gen_rps01.dbf
[oracle@node1 oradata]$ mv gen_cfg01.dbf /u01/app/oracle/oradata/oradb/

4.启动数据库到mount状态
[oracle@node1 oradata]$ sqlplus / as sysdba

5.修改数据文件路径并启动数据库
SQL> alter database rename file '/u01/app/oracle/oradata/gen_cfg01.dbf' to '/u01/app/oracle/oradata/oradb/gen_cfg01.dbf';

Database altered.

SQL> alter database open;

Database altered.

6.查看数据文件路径
SQL> select file_name from dba_data_files;

FILE_NAME
--------------------------------------------------------------------------------
/u01/app/oracle/oradata/oradb/users01.dbf
/u01/app/oracle/oradata/oradb/undotbs01.dbf
/u01/app/oracle/oradata/oradb/sysaux01.dbf
/u01/app/oracle/oradata/oradb/system01.dbf
/u01/app/oracle/oradata/oradb/gen_cfg01.dbf
/u01/app/oracle/oradata/gen_ers01.dbf
/u01/app/oracle/oradata/gen_etl01.dbf

方法2.在线修改数据文件路径

1.查看当前数据文件路径
SQL> select file_name,tablespace_name from dba_data_files;

FILE_NAME                                          TABLESPACE_NAME
-------------------------------------------------- ------------------------------

12 rows selected.

2.offline表空间
SQL> alter tablespace GEN_ERS offline;

3.移动数据文件到新路径下
SQL> host mv /u01/app/oracle/oradata/gen_ers01.dbf /u01/app/oracle/oradata/oradb/gen_ers01.dbf

4.修改数据文件路径
SQL> alter database rename file '/u01/app/oracle/oradata/gen_ers01.dbf' to '/u01/app/oracle/oradata/oradb/gen_ers01.dbf';
