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。

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。
hoegh
