tempfile 'D:\app\Administrator\oradata\orcl\xxx_temp.dbf'
size 50m
autoextend on
next 50m maxsize 20480m
extent management local;

/*第2步：创建数据表空间 */
create tablespace xxx
logging
datafile 'D:\app\Administrator\oradata\orcl\xxx.dbf'
size 50m
autoextend on
next 50m maxsize 20480m
extent management local;

/*第3步：创建用户并指定表空间 */
