Duplicate from Active Database Failing with: RMAN-03009, ORA-17628, and ORA-19505

Duplicate from Active Database Failing with: RMAN-03009, ORA-17628, and ORA-19505 (Doc ID 1439632.1)

搭建备库使用duplicate报错如题，查了MOS，有两个都是说这个问题的：
1. 数据有一部分是非OMF方式创建的，可以使用select tablespace_name,file_name from dba_data_files; 这个语句查看下数据文件的名字，参考MOS(Doc ID 1331986.1)

MOS上给出了两个解决方案：
(1) 使用参数DB_FILE_NAME_CONVERT并使用别名指定数据文件的完整位置；
(2)在备库的磁盘组中创建和原库一样的文件路径
 

2. 目录不存在或者存在的目录有相同的文件也会报如题的错误，参考MOS(Doc ID 1439632.1)

MOS上给出的解决方案：
删除目录中已经存在相同的文件

我的报错是目录不存在，创建个目录就好了
 

以下是MOS原文：
