Oracle recommend, don't use existing VIP (listener). should use Application
VIP
- All databases use one VIP (for listener)
- Each of applications separate VIP (2 applications = 2 vips)
You can define a virtual IP address for an application so users can access
the application independently of the node in the cluster where the
application is running. This is referred to as the application VIP. You can
define multiple application VIPs, with generally one application VIP defined
for each application running. The application VIP is tied to the application
by making it dependent on the application resource defined by Cluster Ready
Services (CRS).
