1、查询表空间位置

select * from dba_data_files;

-->d:\app\administrator\oradata\orcl\***.dbf

2、查看临时表空间位置

select * from v$tempfile

-->d:\app\administrator\oradata\orcl\***_tmp.dbf

3、创建临时表空间

create temporary tablespace icmamp_temp 
tempfile ‘d:\app\administrator\oradata\orcl\icmamp_temp.dbf‘ 
size 100m 
autoextend on 
next 100m maxsize 20480m 
extent management local;

4、创建表空间

create tablespace icmamp 
logging 
datafile ‘d:\app\administrator\oradata\orcl\icmamp.dbf‘ 
size 200m 
autoextend on 
next 200m maxsize 20480m 
extent management local;

5、删除表空间

drop tablespace icmamp_temp including contents and datafiles cascade constraints;

6、创建用户并指定表空间

create user icmamp identified by 123456 default tablespace icmamp temporary tablespace icmamp_temp;

7、用户授权

grant connect,resource,dba to icmamp;

Oracle表空间、用户、授权管理
