Database incarnation does not match that in flashback
database logs. You can workaround this internal error and
restart database by turning flashback off first.

SQL> alter database open resetlogs;

说明：网上也出现诸多flashback to before resetlogs之后出现kcvcrv_fb_inc_mismatch]的情况，我估计是Oracle一bug。数据字典V$DATABASE_INCARNATION存放了INCARNATION信息，利用此信息结合v$archived_log中的归档日志信息，理论上来讲可以穿越resetlogs恢复。（当然这里面涉及到了很多Oracle bug，嘿嘿）
