错误信息：
RMAN-05501: aborting duplication of target database
RMAN-05001: auxiliary file name /oracle/oradata/skatedb/tbs_statspack01.dbf conflicts with a file used by the target database
在用rman duplicate创建dg的时候，抛出如上的错误，这里只列出用rman dumplicate的过程，具体操作步骤如下：

从上面的错误信息可以看到，是因为新创建备库的数据库文件路径名称和主库一样，oracle为了避免错误的覆盖，所以才抛出这样的错误，
只要我们确认这个操作即可。
[oracle@localhost ~]$ sqlplus "/as sysdba"

然后执行如下即可成功，不做数据库文件的名称正确性检查
RMAN> duplicate target database for standby nofilenamecheck;
还可以修改如下两个参数也可以执行成功：
alter system set log_file_name_convert=('/oracle/oradata/skatedb', '/oracle/oradata/skatedb') scope=both
alter system set db_file_name_convert=('/oracle/oradata/skatedb', '/oracle/oradata/skatedb') scope=both
