grant create tablespace to u_name;
grant unlimited tablespace to u_name;
grant select any table to u_name;
grant select any dictionary to u_name;
--3.创建目录 dictionary
create directory directory_name as 'D:\oracleEnv\Oracle\product\11.2.0\db\backup'; --路径可以自己指定
--4.赋予目录权限
GRANT read,write ON DIRECTORY directory_name TO u_name;
--5.创建表空间
create tablespace table_space_name
datafile 'D:\oracleEnv\Oracle\product\11.2.0\dbhome_1\oradata\table_space_name.DBF'
size 2500M
autoextend on next 500M maxsize 12000M;　
--6.修改表空间配置
