expdp通过dblink远程备份数据库脚本+准备

----------fdjExpdp_准备--------------
--sys/Jacjqwl123@orcl
--directory创建(要存放dmp文件端数据库执行)
select * from dba_directories;
create or replace directory jacfdj_data as 'D:\jac_fdj\auto_oracl_bak'
grant read,write on directory jacfdj_data to fdjtest

--network_link创建(要存放dmp文件端数据库执行)
create public database link fdjtest92 connect to 
fdjtest identified by fdjtest using '192.168.33.92/orcl'
