检查备份文件,发现都是存在的,根本没有问题。最后检查发现是incarnation的问题,因为中间我对该数据库做了一次不完全恢复,做了resetlogs操作。
RMAN> list incarnation;

解决方法:
重置数据库的incarnation到2,然后还原数据库,问题解决。关于incarnation的资料,可以参考官方资料7.6.2 Point-in-Time Recovery and Database Incarnations: Concepts
RMAN> reset database to incarnation 2;
database reset to incarnation 2
