Hi,

We have to implement a dataguard between RAC databases 11.2, Customer needs to use the same hostnames on destination site that will be on a different network. To connect primary and standby he will implement a network nat.

We have opened a SR to Oracle in order to understand if this solution is supported, and the answer by Oracle support was "this is not supported, because primary and standby node cannot be identified cleanly."
So, there is an Oracle ufficial note  "Creating a Standby Database on the same Host as the Primary Database(Doc ID 1368884.1)" where  Oracle provide a procedure to create a standby on same host (so, the same hostname too).
