各位好：
我现在安装了 11gR2 的 RAC，其中每个日志组的两个 onlinelog 重做日志文件成员分别存放在两个位置:+DATA/racdb/onlinelog 和 Flashback Area 闪回区: +ARCH/racdb/onlinelog，
那主问我在配置 RAC 为主库时， log_file_name_convert 参数文件该怎么设呢？要不要将两个 onlinelog 位置写上？
*.log_file_name_convert= '+DATA/stdb/onlinelog','+DATA/racdb/onlinelog’
和
*.log_file_name_convert= '+DATA/stdb/onlinelog','+DATA/racdb/onlinelog’,'+DATA/stdb/onlinelog','+ARCH/racdb/onlinelog’
哪个正确？##其中 +DATA/stdb 是指DG的备库目录。
配置这个参数是为了以后主备库能灵活切换。
待复，感谢！
