oracle expdp导出远程数据到本地

1.本地数据库新建一个用户test,并授予以下基本权限（尽量不要多授权，如本地权限大于远程，会导致导出失败，郁闷！）：

grant connect to test;
grant resource to test;
grant create table, create database link to test;
grant create session to test;

2.创建远程dblink

create public database link linkname_xxx connect to username identified by password 
using ‘(DESCRIPTION =(ADDRESS_LIST =(ADDRESS = (PROTOCOL = TCP)
(HOST = 218.65.236.85)(PORT = 1521)))(CONNECT_DATA =(SERVICE_NAME
= orcldev)))‘;

3.创建导出文件目录，并授权给test

 create directory DUMP_DIR as ‘e:\oracle_dump‘;

 grant read,write on directory dump to yx;

4.执行expdp命令

expdp test/abc123@orcl directory=DUMP_DIR dumpfile=eas32.dmp  network_link=linkname_xxx
