How users connections are established on RAC ENV

JhilJan 15 2018 — edited Jan 16 2018

Dear RAC Experts,

>> On Node1

Public   : 192.168.212.40

Private  : 10.0.0.1

Virtual  : 192.168.212.70

>> On Node2

Public   : 192.168.212.41

Private  : 10.0.0.2

Virtual  : 192.168.212.71

Cluster may Active-Active or Active Passive !

>> Is this exactly correct ?

User are initially connected to Virtual IP (which is running on NODE1),

   then user's  connections are routed to Public IP of the NODE1.
