所谓基本的初始化参数指的是运行一个数据库所必需的最基本的参数。 更新顺序Oracle 初始化参数 1. CLUSTER_DATABASE官网连接 该参数指定数据库是否为Real Application Clusters (RAC) 参数类型:布尔型 默认值:False 修改参数需重启数据库 取值范围:True|False 此为基本参数 RAC环境中所有实例都应是True 实际环境截图
If Oracle Database allows multiple instances to mount the same database concurrently, then the CLUSTER_DATABASE initialization parameter setting can make the database available to multiple instances. Database behavior depends on the setting: If CLUSTER_DATABASE is false (default) for the first insta...

对于CRSD资源,在11.2中也进行了重新分类,包括cluster-wide范围的资源,比如SCAN,scan listener, VIP等等,还有一些是local (node-wide)的资源,比如network(注意,11.2把网络也作为了一种资源),eons,asm,diskgroup(11.2把ASM diskgroup也作为了一种资源)等等。 这些资源之间也有相互的依赖关系,比如DG resource依赖于ASM,VI...
集群的节点(Cluster node)——2 个到 N 个节点或者主机运行 Oracle Database Server。 私有网络(Network Interconnect)——RAC 之间需要一个高速互联的私有网络来处理通信和 Cache Fusion。 共享存储(shared Storage)——RAC 需要共享存储设备让所有的节点都可以访问数据文件。 对外服务的网络(Production Network)——...

set cluster_database='false':明确指定备库是单机数据库,这是从RAC到单机的关键配置。 重申路径转换参数: set db_file_name_convert='+DATA','/data','+FRA','/fra' 和set log_file_name_convert='+DATA','/data','+FRA','/fra'。这些参数在Duplicate过程中,指示RMAN如何将从主库获取的ASM文件路径...
