原因在于操作系统下删除了这个归档日志，这个日志还没备份过，rman去备份的时候，找不到这个归档就出错了。可用以下方法解决：
处理:0 U- V- h; y, U$ @6 k
可以在rman命令行执行下面检查语句后再做备份：: e: }# C9 v; p; w
可以在rman命令行执行下面检查语句后再做备份：: e: }# C9 v; p; w
RMAN> change archivelog all crosscheck;
RMAN>list expired archivelog all;
RMAN>delete expired archivelog all;
然后再运行备份脚本,即可顺利进行.
