  -----------------导入语法：新建DOS窗口执行----------------
 //还原到指定用户
 C:\Documents and Settings\Administrator>impdp system/password@database directory=db_bak schemas=databaseName dumpfile=EXPDFileName.dmp logfile=EXPDP.log
 //还原到指定新用户
 C:\Documents and Settings\Administrator>impdp system/password@database directory=db_bak remap_schema=oldName:newName dumpfile=EXPDFileName.dmp logfile=EXPDP.log
  注意：如果你想还原成其他用户，那要将schemas=databaseName 替换成 remap_schema=旧用户名:新用户名
