在使用informatica powercenter 8.5.1的时候，powercenter、目标数据库、源数据库都是装在同一台服务器上，而且所有的数据库版本都是oracle 9201，操作系统是win server 2003，目标表定义方式如果采用的是import from databases的时候，在执行Etl任务都会出现以下奇怪的错误：

简单分析一下错误日志可以发现错误出现数据加载的时候，而数据读取已经成功。而我在执行的时候源定义采用的数据库连接和目标数据库连接全是在odbc中配置好的，使用的驱动程序为”oracle in Orahome92”,即oracle自带的驱动。
实在不知道是什么原因，作了几个其它的简单的测试，只要是目标表import from database都会出现这个错误。
唉，看来只有找informatica售后支持帮忙啦。
