第一步登陆sqlplus登陆用户。

 第二部：创建表空间

第三部：创建用户

代码如下：

CREATE USER "HDS" PROFILE "DEFAULT"
IDENTIFIED BY hds
DEFAULT TABLESPACE HDSDATA
TEMPORARY TABLESPACE temp
ACCOUNT UNLOCK;
GRANT CREATE VIEW TO "HDS";
GRANT "CONNECT" TO "HDS";
GRANT "RESOURCE" TO "HDS";
GRANT DEBUG ANY PROCEDURE TO "HDS";
GRANT EXECUTE ANY PROCEDURE TO "HDS";
GRANT SELECT ANY TABLE TO "HDS";
GRANT SELECT ANY DICTIONARY TO "HDS";
grant unlimited tablespace to "HDS";

  我第四步：导入数据

imp system/orcl@orcl file=E:\oracle\orcl\orcl_his.dmp log=E:\oracle\orcl\log\orcl_his.dmp.log fromuser=SYHIS touser=SYHIS ignore=y
imp system/orcl@orcl file=E:\oracle\orcl\orcl_hds.dmp log=E:\oracle\orcl\log\orcl_hds.dmp.log fromuser=HDS touser=HDS ignore=y

求大神告诫第四步该怎么解决啊？

system/orcl@orcl这个是什么意思？我的数据库设置的信息是

windows用户liuyuqing123
密码：liuyuqing123
数据库全名：orclhd123
管理口令：Lyq7784742839
可插入数据库名：pdborclhd123
EM database Express https://localhost:5501/em

system/orcl@orcl 应该怎么修改呢？
