Linux OS - Version Oracle Linux 5.0 to Oracle Linux 7.4 with Unbreakable Enterprise Kernel [4.1.12] [Release OL5 to OL7U4]
Some application requires associating more than one IP address to one network interface. This KM will show instructions on how to create a Virtual Interface and save it into Linux OS Network Script.
We will modify the /etc/sysconfig/network-scripts/ifcfg-interface manually, and create a new Virtual Interface for the RAC VIP then save it, so that the system will automatically manage it.
