Major curve ball now. The client and management network must be on separate vlans. We have everything as one in our lab network. Why did they not tell us before or make it part of the requirement in the initial document they provided? We have to get all this done and approved by tomorrow if the consulting has to start on Feb 13 – no way it is happening then.
Call with the Oracle software engineer to understand the requirements on what else is needed. Two things remain - Client access IPs need to be on a different subnet and SCAN IPs need to round robin one DNS. Plan to provide inputs asap.
