在数据库已经进入新的incarnation之后，在使用新的incarnation的控制文件来恢复之前的incarnation时会出现以下报错：
RMAN> recover database until scn 1306720;
Starting recover at 04-JUL-16
using channel ORA_disK_1
RMAN-00571: ===========================================================

RMAN-03002: failure of recover command at 07/04/2016 20:12:06
RMAN-20208: UNTIL CHANGE is before RESETLOGS change
解决方法也很简单，使用list incarnation;命令查看所有的incarnation，之后reset database to incarnation x;你想要恢复的备份所在的incarnation即可。RMAN> list incarnation;

可以看到指定正确的incarnation后数据库可以正常进行恢复。
