症状：
执行rman拷贝的时候报错
ora-01276: cannot add file +testdg/rac/datafile/system.416.833384105. file has an oracle managed files file name.
如下：
rman> copy datafile 1 to '+testdg/rac/datafile/system.416.833384105';

copy datafile 2 to '+testdg/rac/datafile/sysaux.417.833384107';

rman-03009: failure of backup command on ora_disk_1 channel at 12/05/2013 15:55:34
ora-01276: cannot add file +testdg/rac/datafile/system.416.833384105. file has an oracle managed files file name.
分析：
error: ora-01276 (ora-1276)
text: cannot add a file with an oracle managed files file name.
---------------------------------------------------------------------------
cause: an attempt was made to add to the database a datafile, log file,
or control file with an oracle managed files file name.
action: retry the operation with a new file name.
asm对omf文件自动命名，对于这种特殊情况，，不能讲copy后的文件与源文件命名一致。
解决方案：
按照oracle的提示修正命令即可：
copy datafile 1 to '+testdg/rac/datafile/system.dbf';
rman>
rman> copy datafile 1 to '+testdg/rac/datafile/system.dbf';
