How to update the IP address of the SCAN VIP resources (ora.scan{n}.vip) (Doc ID 952903.1)

Last updated on JANUARY 17, 2017

Applies to:

Oracle Database - Enterprise Edition - Version 11.2.0.1 and later
Information in this document applies to any platform.

Goal

The purpose of this document is to explain how to change the IP addresses associated with the SCAN VIPs in a 11gR2 Grid (CRS) environment.

The IP addresses associated with the SCAN VIP resources are initially set when the SCAN resources are created.
Any changes to the DNS entry for the SCAN are not automatically propagated to the clusterware and need to be done manually.

This applies only to installations that are not using GNS.

The information in this note can also be helpful in cases where SCAN was originally configured with just one address and is now being expanded to accommodate three IP addresses.
