RAC (Real Application Clusters) Interview Question:

Please tell me what is the function of Grid Naming service used in Oracle RAC?

Submitted by: Administrator

- Oracle RAC provides this Naming service that provides easiness in scaling up the automation of the VIP management system of the Oracle RAC architecture.

- GNS (Grid Naming Service) has to be maintained and monitored by the Network Administrator to maintain the DNS of the system.

- Virtual IP addresses can be maintained by using the cluster and automation can be made in regards of assigning of the IPs.

- Adding of the servers can take place from the pool when the network administrator returns additional IP addresses and GNS requires DHCP server through which it can be accessed publicly.

- The DHCP service of the Oracle allows the dynamic allocation of the Virtual IP addresses that allows the cluster to be joined together in a server.

- GNS provides automation to the system and removes the entire manual configuration with the dynamic nature of the system.
