Oracle Recovery Tools更新—202304

发表于 2023 年 4 月 10 日 由 惜分飞

最近对Oracle Recovery Tools工具进行了升级,增加了在某些恢复情况下对于单个文件的CheckPoint Time的显示,便于判断文件的有效性(便于历史文件区分),该软件是一个恢复小工具,主要定位:
1. 对于某些恢复场景的快速判断,便于问题定位和后续恢复
2. 实现图形化快速修复损坏的oracle数据块和构造块
3. 实现图形化快速修改文件头信息,代替bbed解决文件头的各种scn等问题
4. 快速修改内存中记录,在某些强制拉库的过程中提供便利,特别是在win平台后续版本中无法通过oradebug等方式修改的情况下使用

一键修改Oracle SCN工具升级(patch scn)

发表于 2022 年 10 月 6 日 由 惜分飞

前段时间开发了基于内存修改的patch scn小程序（修改oracle scn小工具(patch scn)），用来修改oracle数据库scn,实现快速调整oracle scn的功能（特别是在一些恢复的时候很有用）,最近对其功能进一步完善，扩展了通过修改oracle controlfile实现调整scn功能,简单测试如下
