Delphix Express is not able to resovle scanname(oracle rac) under seperate VLAN without dns server.Is there any way to edit /etc/named.conf under prebuild delphix engine to fix this issue? Or any ideas who had same issues?
I discussed this with some colleagues to get a consensus before answering. Ultimately, if you need to have name resolution, you need to be able to access a DNS server. The operating system of the Delphix Engine is not accessible, nor modifiable. You could either:
Ask for fw rules to allow you to query the DNS servers
Setup your own little DNS stubs on a Linux/Windows machine in your VLAN to service those requests for you.
