根据以往经验,这个很可能也是tab$数据被删除导致。经过分析,该库的区别是由于该库是12C的pdb
12.1.0.2

pdb
通过分析确认,确实是tab$数据被删除,通过bbed反向删除处理,实现时间完美恢复,open之后删除恶意脚本,数据库直接使用,实现完美恢复

12C数据库遭遇ORA-600 16703

发表于 2019 年 3 月 11 日 由 惜分飞

关于tab$异常的问题,我们在10G(10g数据库遭遇ORA-600 16703),11G(警告：互联网中有oracle介质被注入恶意程序导致—ORA-600 16703)中有发现,近期在12C版本中也发现该问题.再次提醒请注意检查安装介质的md5值和现在运行的库中是否有相关恶意程序
数据库版本
12c-tab-version

处理思路基本上和其他两个版本一样,都是对tab$进行修复,然后直接open数据库,但是在这次的恢复中遇到ORA-00600 kdfReserveSingle_1错误
ORA-600 kdfReserveSingle_1

这个错误主要是由于12c的tab$和以前版本比有一些特殊,导致开始恢复不全,通过继续修复tab$之后数据库正常open.
