由于oracle后续版本对于bbed的支持不是太友好(从10g之后无法直接编译使用,win版本偏移量错误等),基于这些情况,结合当前ai的便利,自己动手写了一个基础版的obet(Oracle Block Editor Tool)【下载obet】,用来实现在某些情况下Oracle 数据块的编辑工作.目前(2025年11月10日)发布第一版主要功能有:
-
通过16进制查看数据文件任何偏移量位置的数据(d/dump)
-
通过16进制编辑数据文件任何偏移量位置的数据(m/modify)
-
对oracle 数据块的tailchk自动修复(tailchk apply)
-
对oracle 数据块的checksum自动修复(sum apply)
-
数据文件之间部分数据拷贝功能(coopy)
-
支持p/print打印Oracle文件头结构

一般情况下文件之间的拷贝就是数据号不一样,比如修改checkpoint,resetlog信息等,这里支持不一样偏移量,不一样数据块的拷贝
