What does Oracle Clusterware do ?
Oracle Clusterware performs the following tasks.
1) Node Monitoring: It manages node membership details. As cluster contains multiple nodes, so it has to keep a record of the nodes that are part of the cluster. And the details about the nodes which are down, and node that are running and part of the cluster.
2) Network Management: Every node in cluster is connected over a network. Oracle Clusterware manages these network component. Clusterware managed Node-VIP, SCAN VIP, GNS-VIP, etc.
3) Event Services: Events such as node going down, instance going down are published to Oracle Clients.
4) Time Synchronization: Having synchronized time between each node is crucial. Oracle Clusterware synchronizes the time of all the participating node.
5) Cluster Management: Eventually Oracle Clusterware manages Oracle Database. It performs actions such as starting/stopping Oracle Database
