---

//管理员登录

sqlplus / as sysdba;

//查询工作目录

select * from dba_directories;

//新建directory

create directory backup as 'D:\app\backup';

//赋权

grant read,write on directory dump_dir to userXX; 

//导出数据

expdp dd/[email protected]/orclcn directory=backup dumpfile=cc_20151113.dmp schemas=dd logfile=cc20151113.log

解析： expdb dd(用户名)/cc(密码)@127.0.0.1/orclcn(地址) directory=backup(刚才创建的directory) dumpfile=cc_20151113.dmp(导出dmp的文件名) schemas=dd(用户名) logfile=cc20151113.log(日志的文件名)
