Hello All - I have a 11.2.0.4 Oracle RAC running on Sparc platform with 3 nodes. I have the scan listeners configured on Network_A and an application is using the scan Listeners. Without impacting the above setup, I would like to create a second database in the RAC environment and setup access for another set of applications through another network Network_B. They both are independent networks (its a requirement based on the legacy networks we have). I need the listener for the second database to be listening on Network_B. Example: Network_A - 192.168.6.x Network_B - 10.120.2.x What are my options in creating such a setup and what are the limitations/constraints in this setup? I'd assume if I bypass the SCAN listeners and access the database listener directly, I'd have to keep up with the cluster changes at the application layer (like node additions/removal etc).. Similar to Oracle 10g RAC - anything else? Thanks much -Upendra
