等保修改oracle SYS用户名要求的请注意—ORA-00600 kokasgi1
重命名sys用户引起数据库启动报ORA-01092 ORA-00600 kokasgi1错误
处理方法比较简单,就是在数据库启动的过程中绕过对SYS用户的检查,然后把user#=0的用户update为SYS（在后续数据库版本中,oracle可能发现了该问题,直接禁止用户级别对user$进行update操作update user$报ORA-01031错误）,再重启库即可

标题：等保修改oracle SYS用户名要求的请注意—ORA-00600 kokasgi1

作者：惜分飞©版权所有[未经本人同意,不得以任何形式转载,否则有进一步追究法律责任的权利.]

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
ora-600-kokasgi1

通过分析确认客户那边在等保的时候要求修改oracle的SYS用户
20230319001510
然后重启数据库，数据库就开始报ORA-600 kokasgi1错误.
再次呼吁:
1. oracle的sys用户名不能修改,这个东西是写在oracle代码里面的，启动的时候会去读取
2.如果已经修改了sys用户名的,请在数据库重启之前一定修改回来

又一例数据库启动报ORA-600 kokasgi1错误的恢复请求

通过咨询是由于根据某厂商给出来的建议对对oracle的user$的系统默认用户update等操作
rename-sys

通过分析现在库的用户情况
20210729084444
通过一系列处理之后绕过kokasgi1错误,open数据库报ORA-12432错误

通过分析启动过程确认数据库在启动的时候访问lbacsys.lbac$pol表异常

PARSE ERROR #2:len=38 dep=1 uid=0 oct=3 lid=0 tim=37509085805630 err=942

USER (ospid: 3512): terminating the instance due to error 12432

经过修改文件让数据库不在访问该表,数据库启动正常
