朋友做1主库、2物理从库的DG配置,配置完成后,,发现有一个从库,始终不能接收到主库的归档日志。
日志不能正常传输到从库,很多都是归档目的地配置的问题,或者网络配置问题。
处理步骤,一般是先看v$archive_dest_status视图,获取概要信息,再查看主库、从库的alert.log日志文件。
在查看朋友主库的v$archive_dest_status时,发现归档目的地3提示错误:
ORA-16053: DB_UNIQUE_NAME string is not in the Data Guard Configuration
再看log_archive_config参数,确实只配置了主库和从库的:
log_archive_config='DG_CONFIG=(primary,standby)'
将第二个从库,加到DG_CONFIG里面,重启数据库,日志就正常传输了。
alter system set log_archive_config='DG_CONFIG=(primary,standby,standby2)' scope=spfile;
