High Availability Architectures and Solutions The Maximum Availability Architecture (MAA) is Oracle's best practices blueprint. It is based on proven Oracle high availability technologies and recommendations. The goal of the MAA is to remove the complexity in designing the optimal high availability architecture by providing configuration recommendations and tuning tips to optimize your architecture and Oracle features.   Oracle Database with Oracle RAC One Node Traditionally, Oracle RAC is used in a multinode architecture, with many separate database instances running on separate servers.
