Oracle Clusterware

Oracle Clusterware — Oracle's cluster coordination infrastructure for membership, resource management, high availability, and RAC-related services.

Oracle Runtime Context

Clusterware monitors resources, reacts to node and process failures, and coordinates cluster membership. Quorum-related storage, network heartbeats, restart policies, and fencing behavior are central to preventing split-brain and unsafe dual ownership.
