一个12.2.0.1的库由于某种原因引起的双机切换,导致数据库无法正常mount

2025-01-04T15:45:44.424193+08:00
alter database mount
2025-01-04T15:45:48.491054+08:00
Network throttle feature is disabled as mount time

Instance terminated by LGWR, pid = 34014

这个错误相对比较明显,是由于ctl异常导致,通过重建ctl,然后mount库,利用Oracle数据库异常恢复检查脚本(Oracle Database Recovery Check)脚本进行检测发现所有数据文件头的checkpoint 信息被冻结在 2024-11-29 19:00:29 （scn 2112302221)
begin-backup

分析alert日志数据库在此后20天中正常提供服务,业务运行都正常,客户反馈在这个冻结checkpoint信息的时间点,使用备份一体机发起过备份,之后就没有再备份了.
当时急着恢复数据库,没有对文件头进行dump不然应该可以发现类似begin backup的信息,类似这样（测试环境重现）：
