Hello Philippe,
Thanks for your feedback.
Well this is a good question that we also asked.
The architects really want the servers to be physically connected through both
networks because they want to use different switches too (not from beginning
but it is planned for the future).
Hope this clears things up.
Seb

Sebastien,
Is it just the db that needs to “listen” on another network or do the machines
need to be separated on other network as well ?

Hi everyone,
I’m posting on this list to get some wisdom from you about network segregation
and EXADATA.
First let me give you the context
We are running 2 EXADATA boxes on different sites.
Box A is for production/ACC DBs
Box B is for DEV/TEST + DRP DBs (Production DBs are protected via Data Guard)
We do not use RAC or RAC On node due to financial constraints and no real need
for scalability or super-HA ☺
Our EXADATA boxes are hosting DBs for different environments (named standard
and industrial – related to the business processes that use them).
Now our architects want to segregate the standard and industrial networks.
On EXADATA we will thus need to handle 2 different networks that cannot be
routed (strict denial on this from security / architect team)
We are only using the copper 1/10 GB NICs for the client access.
I know we can activate and configure the 10 GB fiber NICs to get a physical
access to the second network but if I understood correctly, we would not be
able to use another batch of SCAN ips on this network. So we would need to
configure new VIPs on DB nodes and make the local listeners listen on these /
create new listeners maybe but it won’t be as resilient as SCAN ips
I’m not very comfortable with this kind of requirements and of course, we do
not want to buy additional EXA boxes ☺
Do you guys have any feedback, ideas on how to get things working in a
segregated network environment ?
Thanks for your valuable inputs,
