做dg备库执行duplicate target database for standby nofilenamecheck报RMAN-06023

RMAN duplicate for standby失败解决过程
在用rman duplicate to standby 生成备库的时候总是不成功，多次尝试均是下面的错误：
RMAN> duplicate target database for standby nofilenamecheck;

该问题困扰了我两天，怎么检查也检查不出错误，重做也是同样的问题。
问题1：
set newname for tempfile  1 to
"+data";
这个问题是参数中少写临时表空间的转换参数：
*.db_file_name_convert='+DATA/e7rac/tempfile/','/oradata/e7dg2/datafile/'
加入该参数后，将变成这样：
set newname for tempfile  1 to
"/oradata/e7dg2/datafile/temp.263.804695143";
问题2：
Datafile 部分
set newname for datafile  1 to
"+data";
set newname for datafile  2 to
"+data";
set newname for datafile  3 to
"+data";
set newname for datafile  4 to
"+data";
set newname for datafile  5 to
"+data";
参数已经配置：
*.db_file_name_convert='+DATA/E7RAC/DATAFILE/','/oradata/e7dg2/datafile/'
最后发现是大小写错误：上面路径来自于asmcmd>中的pwd，参数修改为下面的情况后正常。
*.db_file_name_convert='+DATA/e7rac/datafile/','/oradata/e7dg2/datafile/'
正确的路径参数是来自于命令：
select file_name from dba_data_files;
最后正确的执行过程：
