转移数据文件

1.查看数据文件的存储路径：

SQL> select name from v$datafile;

NAME
--------------------------------------------------------------------------------
/u01/oracle/oradata/yoon/system01.dbf
/u01/oracle/oradata/yoon/sysaux01.dbf
/u01/oracle/oradata/yoon/undotbs01.dbf
/u01/oracle/oradata/yoon/users01.dbf

2.修改表空间为offline：

SQL> alter tablespace users offline;

Tablespace altered.

3.拷贝数据文件

[oracle@yoon yoon]$ cp users01.dbf /u01/oracle/oradata/yoondata/

4.修改表空间存储路径

SQL> alter tablespace users rename datafile '/u01/oracle/oradata/yoon/users01.dbf' to '/u01/oracle/oradata/yoondata/users01.dbf';

Tablespace altered.

5.修改表空间为online

SQL> alter tablespace users online;

Tablespace altered.

6.重新查看数据文件路径

SQL> select name from v$datafile;

NAME
--------------------------------------------------------------------------------
/u01/oracle/oradata/yoon/system01.dbf
/u01/oracle/oradata/yoon/sysaux01.dbf
/u01/oracle/oradata/yoon/undotbs01.dbf
/u01/oracle/oradata/yoondata/users01.dbf
