在2019年处理过第一起ORA-00600 kokasgi1 故障到现在,已经过去了近4年,今天又有客户依旧因为修改sys重启库遇到该问题

接到一个朋友数据库无法启动,报错ORA-00600: 内部错误代码, 参数: [kokasgi1]错误:

对于这个错误,以前处理过一些类似故障,参考:
ORA-600 kokasgi1故障恢复
重命名sys用户引起数据库启动报ORA-01092 ORA-00600 kokasgi1错误
通过技术手段实现数据库open,查询user$信息

有客户和我反馈,他们为了防止有人使用sys用户进行登录,对sys用户进行了重命名,具体操作语句为:
update user$ set name='THISISSYS' where user#=0;
然后重启数据库发现数据库无法正常启动,报ORA-01092 ORA-00600 kokasgi1错误

以前写过处理过类似问题,参见:ORA-600 kokasgi1故障恢复,通过特殊处理,数据库open之后,对其user#=0的用户修改为SYS.

至此恢复完成,再次sys是oracle内部默认的超级用户,系统很多调用在程序中写死的sys.,对其用户不能进行重命名操作.

该错误在mos上没有查询出来明确的解决方案,但是在google中有人删除user$模拟出该故障

这里比较明显数据库在查询user$中的SYS用户的时候,无法查询数据从而出现ORA-00600: internal error code, arguments: [kokasgi1]错误.通过进一步对USER$表进行分析发现,sys和system被人重命名
SQL> select name from user$ WHERE NAME LIKE 'SYS%'; NAME ------------------------------ SYSDW SYSMAN SYSTEMDW
定位到具体问题,解决比较简单,在oracle的open过程中,通过对user$表进行修复,实现数据库完美恢复.
