一例正常运行的数据库突然节点不停重启(因为是rac,启动一会儿就crash,然后又被crs给启动起来,然后有crash,依次循环),告警日志类似:

这类的故障在多年前处理过几次
ORA-600 17182导致oracle异常
ORA-00600[17182],ORA-00600[25027],ORA-00600[kghfrempty:ds]故障处理
这个故障的原因是由于block逻辑损坏,实例无法正常做回滚恢复,从而异常.处理异常回滚问题,就可以规避掉数据库启动后一会儿就crash问题.

然后使用逻辑方式导出数据,运气不错业务文件没有任何坏块,system坏块在aud$上,无任何业务数据丢失.

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
