select file_name , tablespace_name from dba_data_files;--查看表空间位置

使用expdp要先在数据库中创建directory,并给相应的用户read,write权限.

SQL>create dexp和empdp的区别irectory dmpdir as ‘/u01/dmdir’;

SQL>grant read,write on directory to test;

job_name:此次导出进程使用的名称,方便跟踪查询(可选)

SCHEMA:导出某一个SCHEMA下的所有数据

 

查看目录Directory位置

select * from dba_directories;

创建目录

CONNECT system/manager 
CREATE OR REPLACE DIRECTORY my_dir as 'D:DataPump'; 
CREATE OR REPLACE DIRECTORY my_logdir as 'E:logs'; 
GRANT read, write ON DIRECTORY my_dir TO scott; 
GRANT read, write ON DIRECTORY my_logdir TO scott;
