oracle11g-expdp-impdp步骤

=========================DMP导出======================
首先建立directory -- expdir（导入导出都要建立,对应的E:/exp文件夹如果不存在，需要手工建立）
SQL>connect zcuser/123456 as sysdba
SQL>create or replace directory expdir as 'D:/SeeyonBackup/DATA';
SQL>grant read,write on directory expdir to public;
SQL>select *From dba_directories;


CMD执行导出命令
expdp zcuser/123456@orcl schemas=zcuser dumpfile=bak20141217.dmp directory=expdir logfile=bak20141217.log


=========================DMP导入======================
----------【DBA用户登入 start】-------
sqlplus system/123@orcl as sysdba 


创建用户：
create user tongji identified by 123456; 
grant dba to tongji;


建立表空间：
create tablespace TONGJISPACE datafile 'F:\oracle\product\10.2.0\oradata\orcl\TONGJISPACE_shdfcm.dbf' size 1M 
autoextend on next 5M maxsize unlimited logging extent management 
local autoallocate


修改默认表空间：
alter user zcuser default tablespace SMGSPACE;


创建dpdata逻辑目录：
create directory dpdata_shdfcm as 'D:\seeyon\install\DB\oracle11gR2\dpdata_shdfcm\';


授权逻辑目录：
grant read, write on directory dpdata_shdfcm to zcuser;


----------【DBA用户登入 end】-------


导入：（在DOS下面进行，后面不要加‘;’号，不然会报“未找到方案 zcuser;”错误）
1、将FUXV520131129.dmp放入逻辑目录dpdata_shdfcm
2、CMD控制台：
//impdp zcuser/123456 DIRECTORY=dpdata_shdfcm DUMPFILE=BAK20141217.DMP SCHEMAS=zcuser
impdp \"tianan/123456@orcl as sysdba\" DIRECTORY=impdp_dir DUMPFILE=20150525.DMP remap_tablespace=OASPACE:tiananspace  remap_schema=V350SP1G:tianan




--------删除用户及表空间，然后手动去oracle目录删除相应DBF文件
drop user zcuser cascade;
drop tablespace zcspace including contents and datafiles
--------删除逻辑目录     
drop directory dpdata_shdfcm;
