这个故障比较明显,根据我们之前的分析经验(警告：互联网中有oracle介质被注入恶意程序导致—ORA-600 16703),应该是tab$被恶意破坏导致,通过分析安装程序,确认是该问题,客户通过互联网上的相关文章,dd方式进行处理,结果数据库报ORA-600 13304错误,无法继续,让我们提供技术支持

通过我们的技术对数据库进行一系列恢复之后,open过程报错

SQL> alter database open;
alter database open

ERROR at line 1:
ORA-01092: ORACLE instance terminated. Disconnection forced

通过跟踪启动过程分析

基本上可以确定是由于客户自行恢复导致props$表异常.通过进一步分析,确认是由于在对tab$处理不合适导致,进一步对tab$进行处理,数据库恢复正常,实现数据0丢失
