impdp报错ORA-39001、ORA-39000、ORA-31619
前不久使用数据泵工具impdp进行数据导入时，遇到报错，提示无效的dunp文件，通过查询文档才知道是由于因为从高版本到低版本不兼容导致的，下面分享一下解决方法。
导入报错
C:\Documents and Settings\hoegh>impdp hoeghto/ilovehoegh directory=data_pump_directory
dumpfile=20150826dynamic.dmp remap_schema= hoeghfrom:hoeghto remap_tablespace= hoeghfrom:hoeghto

添加version参数
源端数据库版本10.2.0.4.0,目标端数据库版本10.1.0.2.0，源端数据库版本高于目标端数据库版本；解决的办法很简单，从源端数据库导出数据时加上目标端version即可，参看一下sql语句：
expdp hoeghfrom/ilovehoegh directory=data_pump_directory dumpfile=20150826dynamic.dmp tables=(HOEGH) version=10.1.0.2.0
接下来，我们再次执行impdp语句就ok了。
