Multiple Networks and the SCAN Listener
IHi Everyone,
HAC that has a dedicated network between the database servers and their application servers. This is in addition to the normal public network.
Would it be better to configure the SCAN listener to the public or dedicated network?
My feeling is that for a 3 node cluster they should:
Have the following sets of IPs available:
Cluster Interconnect - 3
Scan Listener - 3 virtual resolving scan name to all 3
Node VIP - 3 (6 if you want to use 2 sets of node VIPs, one for each network if this is even possible)
Public IPs - 3
I would configure SCAN to support non-Application server traffic (end-users) that don't require the private data network. They would be covered in the event of failure.
