系统：centos 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处理联机&standby日志文件的log_file_name_convert参数时，由于少添加“/”，造成联机日志文件未到指定目录路径下.
正确设置：
'+DATA/orcl/onlinelog/','/u01/app/oracle/oradata/','+FRA/orcl/onlinelog/','/u01/app/oracle/oradata/'
错误设置：
'+DATA/orcl/onlinelog/','/u01/app/oracle/oradata','+FRA/orcl/onlinelog/','/u01/app/oracle/oradata'
异常现象：

说明：可以看到redo日志文件应为” /u01/app/oracle/oradata/group_1.257.1117373983”,standby日志文件应为“/u01/app/oracle/oradata/standby10.log”，其它类似.
以下演示在dg环境下修改主备库redo log和standby log.
1、主库redo
先处理主库redo联机文件.
SQL> select group#,thread#,sequence#,members,status,archived from v$log;
GROUP# THREAD# SEQUENCE# MEMBERS STATUS ARC
---------- ---------- ---------- ---------- ---------------- ---
1 1 77 2 CURRENT YES
2 1 76 2 CLEARING YES
3 2 5 2 CLEARING YES
4 2 6 2 CURRENT YES
取消备库实时应用，设置主备库standby_file_management为manual.
备库操作：
SQL> alter database recover managed standby database cancel;
Database altered.
SQL> alter system set standby_file_management=manual;
System altered.
主库节点1操作：
SQL> alter system set standby_file_management=manual sid='*';
System altered.
SQL> select group#,thread#,status from v$log;
GROUP# THREAD# STATUS
---------- ---------- ----------------
1 1 CURRENT
2 1 INACTIVE
3 2 INACTIVE
4 2 CURRENT
说明：oracle数据库归档必须要剩两组redo log，所以先添加一组新redo log，在删除状态为inactive的redo log.
SQL> select t2.thread#,t1.group#,t1.member,t2.bytes/1024/1024 from v$logfile t1,v$log t2 where t1.group#=t2.group# order by 1,2

小结：主库redo file成功修改.
2、备库redo
修改备库redo log文件.备库redo log无法直接删除，需先设置log_file_name_conver参数.
备库操作：
SQL> create pfile from spfile;
File created.
SQL> shutdown immediate
Database closed.
Database dismounted.
ORACLE instance shut down.
主备库关闭监听，阻止文件传输.
[oracle@hisdbdg ~]$ lsnrctl stop
[grid@hisdb1 ~]$ srvctl stop listener
备库修改pfile后以pfile文件启动数据库
[oracle@hisdbdg dbs]$ vi initorcldg.ora
将log_file_name_convert中的redo转换按如下修改，添加“/”.
'+DATA/orcl/onlinelog/','/u01/app/oracle/oradata/','+FRA/orcl/onlinelog/','/u01/app/oracle/oradata/'
备库操作：
SQL> startup nomount pfile='/u01/app/oracle/product/11.2.0/db_1/dbs/initorcldg.ora';
