文档课题：备库db_create_file_dest和db_file_name_convert&log_file_name_convert同时存在，主库添加数据文件后会按照omf的路径生成数据文件，如何将新添加的数据文件路径修改到和其它数据文件路径一样？
系统：oel 7.9 64位
数据库：oracle 11.2.0.4 64位
环境：rac(双节点) + dg
以下测试过程：
主库添加数据文件.
> alter tablespace users add datafile '+data' size 100m autoextend on;
> select file#,name,status,bytes/1024/1024 from v$datafile

     FILE# NAME                                               STATUS  BYTES/1024/1024

7 rows selected.
说明：+DATA/orcl/datafile/users.553.1116979173为新增数据文件.

以下操作均在备库执行.
