RMAN-06214: Datafile Copy

在使用rman备份的时候最后出现一个这样的错误：

RMAN-06207: WARNING: 1 objects could not be deleted for DISK channel(s) due

RMAN-06208:          to mismatched status.  Use CROSSCHECK command to fix status

RMAN-06213: --------------- ---------------------------------------------------

RMAN-06214: Datafile Copy   /home1/oracle/backup/sh/control2.ctl

然后去该目录下查看该文件发现已经被删除了，那肯定是在os上删除的而不是使用rman来删除的
RMAN>  crosscheck backupset;
使用该命令没有发现该文件，对于datafile copy方式不应该使用backupset方式来检查，而应该使用copy方式来检查；
