WARNING: The 'LOG_ARCHIVE_CONFIG' init.ora parameter settings
are inconsistent with another started instance.  This may be
caused by the 'DB_UNIQUE_NAME' init.ora parameter being specified
differently on one or more of the other RAC instances; the
DB_UNIQUE_NAME parameter value MUST be identical for all

检查LOG_ARCHIVE_CONFIG和DB_UNIQUE_NAME参数配置

SQL> select inst_id,value,name,length(value) from gv$parameter where name in ('log_archive_config','db_unique_name');
