創建導出導入目錄及設置權限

cmd> sqlplus sys/123456@999 sysdba

（檢查目錄字典SELECT * FROM dba_directories;）
SQL> create directory impdp_dir as 'e:\oracle\dump';
SQL> grant read,write on directory expdp_dir to dlerp;
（查看目錄權限 SELECT * FROM dba_tab_privs where table_name='IMPDP_DIR';）

檢查導入環境字符集（針對imp/exp）保證導入導出數據庫的字符集一致
cmd
echo %nls_lang%  
set NLS_LANG=American_America.AL32UTF8（linux-----export NLS_LANG=American_America.AL32UTF8）
