RMAN-06214: Datafile Copy

在使用rman備份的時候最後出現一個這樣的錯誤：
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-06210: List of Mismatched objects

RMAN-06212:   Object Type   Filename/Handle
RMAN-06213: --------------- ---------------------------------------------------
RMAN-06214: Datafile Copy   /home1/oracle/backup/sh/control2.ctl
然後去該目錄下查看該文件發現已經被刪除了，那肯定是在os上刪除的而不是使用rman來刪除的。

RMAN>  crosscheck backupset;
使用該命令沒有發現該文件，對於datafile copy方式不應該使用backupset方式來檢查，而應該使用copy方式來檢查；

Do you really want to delete the above objects (enter YES or NO)? yes
deleted control file copy
control file copy filename=/home1/oracle/backup/sh/control2.ctl recid=788 stamp=784174651
Deleted 1 objects
