每个裸金属解决方案集群均使用 Oracle Real Application Clusters (RAC) 选项实现高可用性。
每个裸金属解决方案集群均使用 Oracle 存储空间自动管理 (ASM) 功能实现存储空间共享。
Oracle ASM 磁盘组名称在集群之间保持一致。
TCP 端口 1521 用于主数据库和备用数据库之间的通信。
第一个裸金属解决方案集群用于托管 Data Guard 主数据库，第二个裸金属解决方案集群用于托管备用数据库。本指南使用 Data Guard 代理来管理配置。本指南还包括有关如何在 Compute Engine 上选择性地配置 Data Guard 观测器的说明。通过配置观测器，您便可以在主数据库和备用数据库之间配置数据库自动故障切换。
