修改Oracle数据表空间存储位置

查看数据文件的存储路径：

SQL> select name from v$datafile;
NAME
--------------------------------------------------------------------------------
/home/oracle/app/oracle/oradata/umpay/system01.dbf
/home/oracle/app/oracle/oradata/umpay/sysaux01.dbf
/home/oracle/app/oracle/oradata/umpay/undotbs01.dbf
/DataBase/app/oracle/oradata/orcl/users01.dbf

1）修改users表空间存储路径

1. 修改表空间为offline
SQL>  alter tablespace users offline;
Tablespace altered.
2. 拷贝数据文件
[oracle@dbhost-33 umpay]$ cp /home/oracle/app/oracle/oradata/umpay/system01.dbf /DataBase/app/oracle/oradata/orcl/
3. 修改路径
SQL> alter tablespace users rename datafile '/home/oracle/app/oracle/oradata/umpay/users01.dbf' to '/DataBase/app/oracle/oradata/orcl/users01.dbf';
Tablespace altered.
4. 修改为online
SQL> alter tablespace users online;
Tablespace altered.

2）修改sysaux表空间路径方式同上

3）修改system表空间路径

1. 关闭数据库
SQL> shutdown immediate
Database closed.

2. 拷贝数据文件
[oracle@dbhost-33 orcl]$ cp /home/oracle/app/oracle/oradata/umpay/system01.dbf /DataBase/app/oracle/oradata/orcl/
3. mount方式启动数据库
SQL> startup mount
ORACLE instance started.
Total System Global Area  534462464 bytes
Fixed Size		    2254952 bytes

SQL> alter database  rename file '/home/oracle/app/oracle/oradata/umpay/system01.dbf' to '/DataBase/app/oracle/oradata/orcl/system01.dbf';
Database altered.
5. 打开数据库
SQL> alter database open;
