使用expdp导出远端的数据库

之前的export命令直接使用exp@remotedb即可实现远程数据的导出，expdp命令稍微麻烦一些，需要使用db link并建相关目录，简单过程如下

1，修改tnsnames.ora

HRTEST =

(DESCRIPTION =

(ADDRESS_LIST =

(ADDRESS = (PROTOCOL = TCP)(HOST = 10.4.×.×)(PORT = 1521))

)

(CONNECT_DATA =

(SERVICE_NAME = HRTESTDB)

)

)

2.在客户端数据库创建DATABASE LINK连接要导出数据的服务端。

SQL>

create public database link "testb36"

connect to test

identified by "test"

using '127.0.0.1:1521/orcl';

Database link created.

3,建目录，并给相关权限

create or replace directory exp_dir as '/data/expdata/';

create or replace directory p_dir as 'd:\';

grant read,write on directory dir to system;

4, 导出数据此处使用clinet端的用户,开始导出数据

export ORACLE_SID=ora11g

expdp system/× network_link=HRTEST directory=exp_dir dumpfile=×.dmp schemas=×

expdp username/password@SID dumpfile=$EXPFILE logfile=$EXPLOG directory=expdir exclude=TABLE:\"LIKE \'MV%\'\", exclude=TABLE:\"LIKE
\'TMP%\'\"
