dmp导出数据源的oracle版本是12c,我本地oracle版本是11g,这在导入数据过程中导致出现错误
一、用system 用户登录oracle，我忘记了system密码，解决办法：
[oracle@yypc ~]$sqlplus "/as sysdba"
SQL>startup
SQL>conn /as sysdba
SQL>alter user system identified by password;
SQL>alter user system account unlock;
SQL>conn system/password
SQL> Create directory TEST as ‘/home/oracle/Desktop/test‘;
SQL> Grant read,write on directory TEST to scott;
SQL> SELECT * FROM dba_DIRECTORIES;
问题： 1、日志和dmp文件不能有路径，dmp文件放到directory所创建的路径下（ ‘/home/oracle/Desktop/test‘），log文件oracle会自动保存在$ORACLE_HOME目录下
[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

问题2：版本所引发的问题，解决高版本向低版本

源端数据库版本12c,目标端数据库版本11g，源端数据库版本高于目标端数据库版本，源端导出数据时加上目标端version，
查询版本SQL> show parameter compatible;
Linux 下 oracle 导入数据库—数据泵方式导入dmp文件
