Home -> Community -> Mailing Lists -> Oracle-L -> Re: IP change and TNS Names, etc.
I would do the following, assuming you are running DNS server:
Do this now:
1. Add DNS entry for each Server.
2. Change tnsnames entries to be hostname, not ip.
Do this after switch to private ip addresses: 1. Change DNS entry for each host from public ip to private ip.
There are a couple other ways, but this is the cleanest. If you are accessing these hosts from the internet, remember to set up your firewall rules/NAT.

Hello Gurus:
We are in the process of changing over our IP addressing scheme to a private network behind a firewall. This meant that all out servers are going to get new IP addresses. I know that our TNSNames file has IP addresses in it that will have to be changed. What other places will I have to look to make sure everything still works when we switch? Is it possible (advisable) to replace the IP address with a DNS hostname?
We are running Oracle 7.3.4 on HP/UX and OAS 4.x on a Sun Enterprise 450
Thanks
