EXPDP,IMPDP远程导出，导入数据库到本地
1.本地建立导出用户hr_exp并完全删除机hr的用户

C:\Users\Administrator>sqlplus / as sysdba

With the Partitioning, OLAP and Data Mining options

SQL> create user hr_exp identified by hr_exp;

用户已创建。

SQL> grant connect,resource,create database link to hr_exp;

授权成功。

SQL> drop user hr cascade;

2.在操作系统上创建目录

SQL> conn / as sysdba

已连接。

SQL> create or replace directory DIR_EXP as 'd:\direxp';

目录已创建。

SQL> grant read,write on directory DIR_EXP to hr_exp;

授权成功。

3.解锁远程用户的hr的帐户并修改其密码为hr

C:\Users\Administrator>sqlplus system/root@192.168.11.2:1521/orcl

SQL*Plus: Release 10.2.0.1.0 - Production on 星期一 10月 27 15:16:54 2014

SQL> conn hr_exp/hr_exp
已连接。
SQL> create database link to_exp_hr
2 connect to hr identified by hr
3 using '(DESCRIPTION =
4 (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.11.2)(PORT = 1521))
5 (CONNECT_DATA =
6 (SERVER = DEDICATED)
7 (SID = orcl)
8 )
9 )';

数据库链接已创建。

另外一种数据连接创建方式
SQL> create database link to_exp_hr connect to hr identified by hr using '192.168.11.2:1521/orcl';

SQL> Select 1 from dual@to_exp_hr;

1
----------
1

SQL>

5.导出hr的数据
C:\Users\Administrator>expdp hr_exp/hr_exp@192.168.11.1:1521/orcl directory=DIR_EXP dumpfile=hr_20141027.dmp logfile=hr_20141027.log network_link=to_exp_hr
