Oracle 23ai rm redo*.log恢复
在oracle 23ai的pdb中创建用户和表,并且插入数据(不提交),在另外一个会话中abort库,并从os层面rm删除掉redo文件,模拟数据库当前redo丢失,数据库恢复

尝试启动数据库,报ora-00313,ora-00312,ora-27037等错误

由于所有redo均被删除(包含当前redo),因此只能强制resetlogs方式打开库,尝试打开数据库

数据库遇到常见的ORA-600 kcbzib_kcrsds_1错误,这类错误类似oracle在12c之前版本中的ORA-600 2662错误
ORA-600 kcbzib_kcrsds_1报错
存储故障,强制拉库报ORA-600 kcbzib_kcrsds_1处理
redo异常强制拉库报ORA-600 kcbzib_kcrsds_1修复
ORA-00603 ORA-01092 ORA-600 kcbzib_kcrsds_1
这种一般就是scn问题,通过修改数据库scn,数据库启动报ORA-16433错误
