Real Application Clusters
Oracle Real Application Clusters (RAC) allow customers to run a single Oracle Database across multiple servers in order to maximize availability and enable horizontal scalability, while accessing shared storage. User sessions connecting to Oracle RAC instances can failover and safely replay changes during outages, without any changes to end user applications, hiding the impact of the outages from end users.
New Generation Oracle RAC
Oracle Real Application Clusters 19c includes many improvements that enable applications to achieve significantly better levels of availability and scalability than previous versions. These improvements create a new generation of Oracle RAC technology ready to meet the needs of next-generation workloads and applications.
