dmp導出數據源的oracle版本是12c,我本地oracle版本是11g,這在導入數據過程中導致出現錯誤
一、用system 用戶登錄oracle，我忘記了system密碼，解決辦法：
[oracle@yypc ~]$sqlplus "/as sysdba"
SQL>startup
SQL>conn /as sysdba
SQL>alter user system identified by password;
SQL>alter user system account unlock;
SQL>conn system/password
SQL> Create directory TEST as '/home/oracle/Desktop/test';
SQL> Grant read,write on directory TEST to scott;
SQL> SELECT * FROM dba_DIRECTORIES;
問題： 1、日志和dmp文件不能有路徑，dmp文件放到directory所創建的路徑下（ '/home/oracle/Desktop/test'），log文件oracle會自動保存在$ORACLE_HOME目錄下
[oracle@yypc ~]$ impdp scott/youyou full=y directory=TEST dumpfile=/home/oracle/Desktop/ExpIirspublish20141117.dmp logfile=/home/oracle/Desktop/imp_icdmain_csd_X.log ignore=y

問題2：版本所引發的問題，解決高版本向低版本

源端數據庫版本12c,目標端數據庫版本11g，源端數據庫版本高於目標端數據庫版本，源端導出數據時加上目標端version，
