create directory szs1 as ‘F:\szs_nn\20140905adms\‘;
--查看目录
select * from dba_directories;
--赋权限
grant read,write on directory szs1 to szs;
grant all on directory szs to public;
-- 在本地建立目录d:\bak，并将需要还原的数据文件放到该目录下 原schema nc 导入dzbank

--11G exp导出表时设置空表导出
--注意:该值设置后对以前导入的空表不产生作用，仍不能导出，只能对后面新增的表产生作用

--11G 设置表空间默认大小 文件32G以上大文件（建立表空间之前设置）
