确实如alert日志报错,file 3和9 都出现坏块导致实例恢复无法进行。根据错误ORA-600 2037和ORA-7445 _kcbs_dump_adv_state,初步判断和During Startup (Open Database) Alert Log Shows ORA-600[2037] and ORA-7445[kcbs_dump_adv_state] (Doc ID 551993.1)文章描述相符(而且版本也相符)

ORA-00600 kcratr1_lastbwr错误比较明显,见ORA-00600:[Kcratr1_lastbwr] During Database Startup after a Crash (Doc ID 393984.1)
通过recover database处理
SQL> recover database; 完成介质恢复。 SQL> alter database open; 数据库已更改。
然后通过查询dba_extents 处理坏块对象
补充ORA-600 2037错误
