Oracle创建表空间

/*分为四步 */
/*第1步：创建临时表空间 */
create temporary tablespace IMS_DATA
tempfile 'D:\oracledata\yuhang_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 IMS_DATA
logging
datafile 'D:\app\Lihe\oradata\orcl\IMS_DATA.dbf' --先看本地文件
size 50m
autoextend on
next 50m maxsize 20480m
extent management local;

/*第3步：创建用户并指定表空间 */
create user ims identified by akin2011
default tablespace IMS_DATA;
--temporary tablespace yuhang_temp;

/*第4步：给用户授予权限 */
grant connect,resource,dba to ims;

/*收回用户的DBA权限*/

revoke dba from ims;

/*修改用户密码*/
alter user his identified by akin2011;

/*删除用户*/
DROP USER emr CASCADE;
