Clustered Environment - Changing from Public Network to Private Network

[Former Member]

I have a clustered environment where the database sits on one node and the central instance sits on the other node. We just found out that somehow the communication between the database and central instance has been changed to talk over the public network instead of the private network. We don't know who did it or why.

So, my question is what do I need to do in SAP to accomodate the changing back to using the private network? Do I need to change system names in the profiles? Are there any gotchas on doing this? Are there any documents on doing this?

Thanks for any information you can provide on this topic.

Thanks,

Excuse me, the public NETWORK is used to ping from one server to the other.

The Public name is used.

This is most likely a name resolving problem.

If you ping <name> from one server to the other, which network is used?
