Oracle Clusterware is a software suite that provides infrastructure for Oracle Real Application Clusters (RAC) to enable high availability and scalability. It manages cluster resources such as databases and applications, ensuring they run smoothly across multiple servers. Clusterware monitors the health of these resources and automatically handles failures to minimize downtime.
