搭建dg在执行duplicate命令时 报错RMAN-05517

系统：oel 7.9 64位

数据库：oracle 11.2.0.4 64位

环境：rac(双节点) + dg

问题描述：搭建dg在执行duplicate命令时，报错RMAN-05517,如下所示：

RMAN-00571: ===========================================================

RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============

RMAN-00571: ===========================================================

RMAN-03002: failure of Duplicate Db command at 10/01/2022 20:44:20

RMAN-05501: aborting duplication of target database

RMAN-05517: tempfile +DATA/orcl/tempfile/temp.266.1107818221 conflicts with file used by target database

异常原因：

用spfile生成pfile文件后，查看log_file_name_convert、db_file_name_convert参数发现tempfile的转换路径编写错误.

修改后异常不再发生.
