1.先使用控制文件构筑好PHYSICAL STANDBY环境(Primary:Single 11.2.0.4,Standby Single 11.2.0.4) 2.构筑好Catalog用的服务器(Catalog:Single 11.2.0.4) 3.构建Catalog |SQL> startup mount ------------------Mount启动|ORACLEインスタンスが起動しました.||Total System Global Area  839282688 bytes|Fixed…

一.切换前检查1.检查备库已经全部接收到主库的redo如果是最大可用性.最大保护性模式,可以在primary端查看v$archive_dest_status,确认是否所有的redo已经传送到备库#在主库执行 SQL> select db_unique_name,protection_mode,synchronization_status,synchronized from v$archive_dest_status; DB_UNIQUE_NAME PROTECTION_MODE SYNCHRON…

下面是我自己建Physical Standby,按照下面的步骤一步我一步,当然,打造成功,以下步骤可以作为建筑物Data Guard结构操作手册. HA和DG差额:HA:可以做IP切换自己主动  DG:做IP切换自己主动 备库和RAC的接点个数没有关系,(生产库多少个节点,备库就是多少个节点),Oracle必须是企业版(Enterprise Edition)才干够做DG DG级练 A->B->C(ABC能够相互切换) 主备库配置环境: ORACLE VERSIOIN: Release 10.2…
