windows和linux下BBED使用体验

最近遇到到某个库的文启动中，数据文件SCN号不一致，本想按常规做，没有备份和归档。强上BBED，使用bbed修复损坏datafile header前推一致SCN号，启库。
需要说明的是，我下载了BBED到window环境下，操作过程中发现， p kcvfhckp这一步总是在报错。网上查了好多原因不得要领，不得已，将window环境下 datafile 11 移动到linux环境下解决。

这个是我window下报错截图，希望有高人能指点一下，如何解决报错问题。因为当window下数据文件过大的时候，来回迁移是不现实且低效的。

按照网上前人的经验，我在linux再次做一次实验：
