新搭建的环境，还没上线，今天在部署脚本，RMAN 备份中有一个警告，内容如下：
RMAN-06207: WARNING: 1 objects could not bedeleted for DISK channel(s) due
RMAN-06208: to mismatched status. Use CROSSCHECK command to fix status
RMAN-06210: List of Mismatched objects

RMAN-06213: ------------------------------------------------------------------
RMAN-06214: Datafile Copy /u01/control01.ctl
这个文件是DG的一个控制文件，环境弄好之后，就把这个文件在OS 级别rm 掉了。结果备份就报这个错误。
