Connected to: Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bit Production

ORA-39001: invalid argument value
ORA-39000: bad dump file specification
ORA-39142: incompatible version number 3.1 in dump file "D:\databak\BOSDATA.TM_LOGITRAK.dmp"

查看版本后发现，原端数据库版本是PL/SQL Release 11.2.0.1.0 - Production expdp导出数据，impdp导入端的数据库版本是PL/SQL Release 10.2.0.4.0 - Production

从高版本导入低版本数据报错，empdp导出时加入version选项
