Oracle Domain Service Cluster可以向Oracle Cluster Domain中的其他集群提供集中的服务,这些服务包括:
-Grid Infrastructure Management Repository (GIMR)
为Oracle集群域中的每个集群提供MGMTDB
-Trace File Analyzer Collector (TFA)
用于Oracle Clusterware和Oracle Database的目标诊断数据收集
-Rapid Home Provisioning (RHP)
用于安装集群、提供、修补和升级Oracle Grid和Oracle Database
-Storage Services
ASM Service (direct access to centralized storage)
通过SAN网络直接访问Oracle Domain Service Cluster中的存储,当然也可以使用Local Storage
IO-Service (indirect access to centralized storage)
通过ASM网络访问DiskGroup,无需用连接SAN网络
如果安装为Oracle Domain Service Cluster,需满足下面的条件
1.配置DNS、DHCP并使用GNS
2.需要一个空间足够大的DiskGroup用于MGMTDB,IOS,RHP等服务的存储空间
12.2中需要350G的空间,18c中需要450G的空间
