Removing a DNS Server
Hello everyone,
I have a single forest with
multiple domains .
We have five Domain Controllers,some of
them are Server 2008 R2 and others Server
2012 R2(On all installed DNS server)
I recently started to upgrade the DC 2008 R2 to 2012 R 2 and now i would like to remove the DNS server from DC 2008 R2.
All the zones in all DNS servers are Active Directory - Integrated zone.
I found this article : http://technet.microsoft.com/en-us/library/cc794727(v=ws.10).aspx ,
but do not really understand the first two items.
How I remove the DNS server from the forest?
Thanks in advance,

Greetings!
If you are upgrading your domain controllers to 2012, why are you taking this method? If you want to keep this DC operational do not remove the DNS server separately or you will experience difficulties during installing DNS again. Transfer FSMO roles to
an available DC and demote 2008 servers and re-promote after installing 2012.
Regards.

How to remove a DNS entry from Network Preferences
When I checked Network Preferences today, I discovered 2 DNS servers listed in +System Preferences > Network > Ethernet > Advanced > DNS.+ There have never been any DNS servers listed there before.
One of them is my home router; the other is a server that to my knowledge I have never accessed. I did not add these servers to my system and have no idea how they got into my Network Preferences.
I would like to remove them but cannot find any way to do it. The addresses are greyed out and cannot be selected to be removed.
Yes, I unlocked the preference pane.
No, there are no DNS servers listed in my Airport configuration.
Both connections work fine.
I just want to remove the DNS server addresses.I think I found the answer.
The grey DNS server entries are coming from my router. I can see them appear in the DNS pane when I connect the ethernet cable. Also checked my router and that's the DNS address specified in the router setup (Actiontec MI424WR). There is also no evidence of a potential DNSchanger/RSPlug/Jahlav trojan.
Based on info I found in the Verizon FIOS forums & DSLreports, the 71.242.0.12 address appears to be Verizon DNS server nsphil01.verizon.net, which would make sense as I have FIOS internet. But I don't quite understand why a WHOIS request on the address returns these server names: NS1.THOMASLORD.NET and NS1.ACCESSMYEMR.COM -
DNS server process, high CPU usage
Hello,
I am having a problem with high CPU usage on DNS process. We have 1921 setup in network of about 100 workstations that use it as DNS server. It also performs split view functionality for couple of domains in order to avoid hairpin NAT. I know that a router is not fit for heavy server duty but such setup was unfortunately necessary.
In peak work hours we oftenly have CPU hitting 100% with DNS server process being the root cause,and on several occasions we had DNS process stuck in such state for prolonged periods of time during which other router functions were affected (t's a default gateway, IPsec concentrator etc.). Sometimes shutting the process and restarting it would solve the problem, but once it required a full reload in order to restore functionality (such was the description that engineer on duty reported to me).
Forwarder queue statistics:
Current size = 0
Maximum size = 86
Drops = 0
IOS upgrade did not help, we are currently running 15.2(2)T.
The question is ... is such behaviour (CPU load) to be expected on LAN with 100 workstations due to slow CPU on router or we have bugged IOS DNS server (requiring a TAC case)?
The previous solution seem to do this functionality quite nicely (even though it was also a router), so I am not inclined to think that we are dealing with someone DoS-ing the DNS (WAN access to DNS is of course forbidden)
P.S.
Since we moved servers off the routers DNS, we do not receive complaints, but we had a couple of unresolved messages a day while mail server was using router for DNS. I am suspecting that an old bug where IOS DNS servers occasionaly sends clients back empty DNS replies (properly formatted message but without A record) could be still around?hi,
i have the same problem on UC540 and 2911 on IOS 15.0.1. CPU high, router crashed. Reboot helps but until CPU usage spikes again. the only fix is to remove "ip dns server" from config and use a different DNS server

Moving from Exchange 2007 to 2013 (leaving the DNS Server for it's own dedicated server)
Hello! I am quite new to Exchange and Server management in general. I will do my best to explain my situation.
I am looking to move my Exchange server off of our DNS server. When we installed them on the same server, we did not have the funds to buy 2 separate servers. I am told that it is best to separate the two. I have followed the Microsoft instructions for installing
the prerequisites for Exchange 2013 on a 2012 R2 server, and i am at the point where it wants me to configure AD LDS. As I have active directory running on the current server, I was a little hesitant to just install it without understanding what i am doing.
After the AD LDS is configured, I believe i can move forward with installing Exchange 2013 (all 3 roles will be hosted on the new server), export the mailboxes from 2007 server and import them into the new Exchange 2013 server. After 2013 is up and stable,
I plan on removing 2007 from the old server (DNS server).
What are my next steps after importing the mailboxes? Am i missing important details that I need to change or migrate?
My biggest fear is that nothing works after the installation and moving the mailboxes over. For that case, it makes sense to keep 2007 installed as a fallback for when my installation fails and all i have lost is just my time :)
Current Server:
Windows Server 2008 Standard (64 bit)
1. Roles: Active Directory, DNS, IIS
2. Software: Exchange 2007
New Server:
Windows 2012 R2 Server
1. Roles: ???
1. Software to install: Exchange 2013
Thank you for any help you can provide!These are good resources, but i am still caught up with the active directory issue. Am I able to keep the old Domain/DNS/Active directory on it's current server and move Exchange 2007 off onto a new server (with Exchange 2013)?
In the first example, he is moving everything (domain controller, exchange, users, etc) onto a different server and decommissioning it.I've been told that it would be better practice to keep the domain and exchange on 2 different servers. Is this true?
I go to run commands like:
.\setup /PrepareAD /OrganizationName: orgname /IAcceptExchangeServerLicenseTerms
on the new exchange server, as a prerequisite and it doesnt recognize the command - even after following the steps before. Is this because the new server is not a domain controller? does it have to be? What are the best practices for setting up a server(s)
with exchange + domain controller?
Thanks for responding. -
I originally posted this question to the community section and was advised to post it here. Please bear with me as this will be a long post. I'm including the scenarios involving this reoccurring issue, the trouble shooting steps I've already
taken and the results of several diagnostic tools and logs.
I have a Sony VAIOS VPCEBB33FM lap top since 2011. I have had this issue on an off for a long time. I'm at my wit's end. Any new insights or suggestions would be greatly appreciated.
Scenario Details
1) Some times it's on and off through out the day, sometimes it won't work all day, and once in a while it will work fine for the entire day.
2) I've had this issue across several wireless services, Clear Network accessed with WiMax, Library Wi-fi, Comcast cable internet using wireless router and Wi-fi, and Comcast Xfinity Wi-Fi, to name a few examples.
3) Other devices in the household or library will work with no problems such as my smart phone or my roommates' laptops or desktop computers.
4) Once in a while, the built-in wireless adapter is not found and I have to reinstall the driver. Also the diagnostic tool has had to reset my adapter on an increasing basis.
5) I had my hard drive replaced in December 2014 and my system restored from the System Restore disks that came with it when I bought the laptop. Even though I've been online on an infrequent basis it worked just fine for a while. Now that
I've been online a bit more I'm having the same issues again.
Below are my attempts at trouble shooting so far but I still have not been able to consistently resolve my DNS issues
1) Restarting my adapter
2) Turning off my laptop and removing the power supply for 5-10 minutes before turning it back on.
3) Using the IP Config in Command Prompt
ipconfig /flushdns
ipconfig /registerdns
ipconfig /release
ipconfig /renew
4) Using the NetSh reset in Command Prompt and restarting my laptop
netsh int ip reset c:\resetlog.txt
netsh winsock reset
ipconfig /flushdns
[restart laptop]
5) Configuring the TCP/IP in several settings
Select Internet Protocol Version 4 (TCP/IPv4), and then click Properties.
I have used the following settings:
a) Obtain an DNS server address automatically
b) OpenDNS
208 67 222 222
208 67 220 220
c) Google DNS
8 8 8 8
8 8 4 4
6) Updating the driver for my Intel Centrino(R) Advanced-N 6250 AGN and Intel Centrino(R) WIMAX 6250 from the Intel website previous having my laptop wiped clean in 2014. It still did not resolve the issue. My laptop
manufacturer as not come up with an driver update for my adapter since 2010. I haven't tried to update the adapter driver from Intel's website since having my laptop repaired due to the fact that Intel strongly recommending using the manufacturer's updates
instead and frankly it didn't make much of a difference when I did it the first time.
7) The last one I've tried as of today is going into Services and changing the start up type to automatic for the following:
Computer Browser [changed from manual to automatic]
DHCP Client [already set to automatic]
DNS Client [already set to automatic]
Network Connections [already set to automatic]
Network Location Awareness [changed from manual to automatic]
Remote Procedure Call (RPC) [already set to automatic]
Server [already set to automatic]
TCP/IP Netbios helper [already set to automatic]
Workstation [already set to automatic]
...and I'm still having DNS issues.
My only guessing are that my laptop came with a lemon adapter that needs to be replaced, some advanced setting(s) that I'm not aware off, or my firewall/anti-virus is interfering. I've used Symmantic Anti-virus and Firewall in the past and currently
Avast Anti-Virus with Microsoft Network Firewall. I've had DNS issues with both anti-virus/firewall set ups.
Below are the results from the diagnostics and tests that I've ran.

New HP LaserJet Pro MFP M127fw network connection impacts DNS server of my ISP
Hi,
i am not well with english, so please sorry
I have deliverd new HP LaserJet Pro M127fw to my client who have 3 PC-s Win7 64bit, one 4 port switch, and one TP-link ISDN modem-router.
I have installed the printer over network and everything is done well. Printer is working in printing/scanning/fax/ and copy.
In few hurs local ISP has called and said that his DNS server is impacted by something from local LAN. After investigating, i have fount that printer is doing impact to DNS of ISP. When i remove LAN cable from printer, everything is fine with network
I have installed new frimware from HP.com. also I have change Admin pass. The new up to date software is installed.
Still have problem, and no solution. For now printer is working with USB connection, but that is not a option.
HP please help!Hi @ITMračunari ,
I see that you are having issues with the printer connected by a Ethernet cable to the network, the printer is impacting the DNS of ISP. I would like to help.
Turn the IPv6 off on the printer to see if that will help.
Go to Setup, Network Setup, Network Services, IPv6 and turn it off.
This is a Consumer product and has been proving to work with a direct connection to a router.
I noticed in your post that you are also using a switch, which could possible cause other conflicts.
Hope this helps.
Have a nice day!
Thank You.

Can't override DNS Server settings - can only append!
See this thread for a similar question:
http://discussions.apple.com/thread.jspa?messageID=3555096
I have also filed this with Apple (Problem ID 5159216). Here is the text of the report (with a few bits removed - not crucial to understanding the report).
If anyone has suggestions/clues to resolve, please advise. Thanks!
Summary:
This problem concerns AirPort Extreme (802.11n) at revision 7.1. I will summarize with a comparison between AirPort and MacOS X.
MacOS X and Airport Extreme (referred herein as "AE") both permit editing of DNS server settings whether in DHCP or Manual mode.
When MacOS X DNS server settings are set manually by the end-user, the new server IPs are used (good). When AE's DNS server settings are overridden by the end-user, the new server IPs are NOT used (not good)! Rather, the DHCP-supplied DNS server always pre-empts whatever is given in the AE Configuration UI.
Steps to Reproduce:
1. Using AirPort Extreme (802.11n) at revision 7.1 and MacOS 10.4.9 on a MacBook Pro (Core 2 Duo). The AE has been previously configured for IPv4 using DHCP and the MacBook is successfully connected and resolving domain names through the AE.
2. Visit "Apple Menu > Location > Network Settings" and check the AirPort TCP/IP settings. For purposes of this test, make sure the "DNS Servers" field is EMPTY so MacOS X defaults to the AE's DNS settings, then close System Preferences.
3. Run "AirPort Utility" (the newer version, not "Airport Admin Utility") and configure the AE under test. Pick the "Internet" icon in the toolbar and note the Internet Connection settings.
4. In this test, Configure IPv4 is set to "DHCP" and the DNS Server(s) field contains two DNS IPs assigned by the Internet Service Provider. In my case that's Cablevision's Optimum Online service. You may or may not see IP addresses here, but in my case they are visible.
5. As the DNS Server(s) are editable, and they both show ISP-supplied addresses, they can be changed to whatever alternate IPs you wish. For instance, change them to these alternate DNS IPs from OpenDNS.com: 208.67.222.222 and 208.67.220.220. (You could use any alternate set of IPs but for the purpose of this test use the OpenDNS IPs.) Update the AE and restart.
(For additional reference, http://www.opendns.com/start/airport.php shows instructions for the older AirPort Admin Utility, but the concept is exactly the same.)
6. Normally you shouldn't have to restart the MacBook Pro since we're just using the AE settings, but go ahead and do that just to be consistent with this test.
Expected Results:
Now for the moment of truth! We want to verify that we're using the OpenDNS IPs for our DNS Servers. One nice feature OpenDNS has is automagic redirection for certain domain name typos.
Here's an example. Drop to shell (Applications > Utilities > Terminal) and try this command (excluding the $ prompt, natch):
$ dig craigslist.og
The "og" typo is deliberate. We really want to go to craigslist.org. If you're using the new OpenDNS IPs, you will STILL get an Address (A) record with an IP like so:
;; ANSWER SECTION:
craigslist.og. 0 IN A 208.69.32.130
If you had entered "craigslist.og" in Safari, you would end up at 208.69.32.130 (an OpenDNS server) and then redirected to craigslist.org.
Actual Results:
Alas, that's not what happens! Instead, you get NO IP address, like so:
;; QUESTION SECTION:
;craigslist.og. IN A
This means we're not actually using the OpenDNS IPs. What's happening?
To find out, I spoke with the AirPort support group (Case # xxx-xxx-xx). I learned that, despite being allowed to edit and override the IP addresses provided via DHCP, the AE still uses the DHCP-provided DNS server if available.
Again, the user interface suggests that I'm allowed to override the DHCP-provided DNS IPs as shown in the UI. Even though I can do this, the AirPort will still keep note of any DHCP-provided DNS Server IPs and use those first.
True, I can switch to Manual network settings (and then my own DNS Server IPs take effect). Of course this is problematic when the ISP renews my IP address (which it does from time to time).
Another workaround is to use the "DNS Servers" settings noted in step 2 (above). However this is also problematic if I want to keep my network settings simple. It requires a "Home Network" location and an "Office" location. Still not preferable, but it's a workaround.
Regression:
n/a
Notes:
I would like AirPort's DNS settings to be overridden in the same way OS X allows DNS settings to be overridden. The user interfaces suggest this is possible but it is not. It's only possible in the OS X case. Having the same flexibility on the AirPort would be most welcome.Afraid of the answer...sheesh...you must be a child. This has nothing to do with masquerading anything. The issue being discussed here is that people want to manually assign a dns server address via the new AEBS, while maintaining DHCP for IP address assignments through their ISP. For example, I would like to have opendns.com take care of all dns addressing at the router level, even though I have "Configure IPv4" set to "Using DHCP". If you do not understand why one would want to use something like opendns.com, please visit their website and enlighten yourself. The fact that the dns server address fields are editable when set to "Using DHCP" leads one to believe that you can manually assign a dns server in this configuration; however, under firmware 7.1.1, you still cannot. The previous iteration of the airport hardware can do it, as can nearly any router you pull off the shelf. In addition, this is something that can easily be done at the individual-computer level in OS X; however, many people would prefer to administer their network at the router level. That is the issue being discussed here. Either you can't read or you are purposely derailing the thread.

DNS debug logging to determine if 2008R2 DNS server is still being queried?
We are removing multiple DNS servers. We have removed those servers from DNS reference from all dhcp scopes, and ran script across all windows servers to make sure they are not being used. There still might be Linux/telecom/workstations manually
set that we do not know about, so I was going to use debug logging just to look for queries that are coming and to try and determine where they came from. I have debug logging set to log packets for Incoming, UDP, Queries/Transfers, and Request, but having
trouble figuring out this log. Here is an example of what I am seeing. Does anyone have a reference for this? I am having trouble finding one.
Is this saying that a computernamed POS188 made a query for a host(A) record? or is it saying that a query came in from 128.1.60.221 for a host(A) record named POS188? Just looking for reference to help explain this. The good news is the only
IP address that shows(128.1.60.221) is the IP of the DNS server, but the only thing I could find for reference was this -

Thanks,
Dan HeimHi Dan,
The example you provide means that the DNS server receive a packet sent by 128.1.60.221,and the packet is used to query a host(A) record named POS188.contoso.com.
And the detail information about each field of the message is shows below. It is also showed in the dns.log.

Leopard DNS Server: Zones with SPF records?
Hi all,
I'm trying to figure out how to setup SPF (Sender Policy Framework) records for some domains I'm currently managing with a Leopard DNS server and I don't see any documentation anywhere. Can someone please tell me if it's even an option? I'm new to running DNS with Leopard, so I could use all the help I can get.
Sincerely,
Israel

Can you give me an example of how it looks in your zone files? I’ve pasted a sample of mine below. Tell me if anything is wrong.
Israel,
I am new to Leopard Server - so I'm no DNS guru. I, too, have not used a DNS setup tool that requires a FQDN just associate an IP with the base of the domain (mydomain.com.). How did you get your 'mydomain.com. IN A 11.22.33.44' accomplished? Did you create a new A record and put mydomain.com. in the Machine Name field?
Here's my setup:
========================
db.mydomain.com

;THE FOLLOWING INCLUDE WAS ADDED BY SERVER ADMIN. PLEASE DO NOT REMOVE.
$INCLUDE /var/named/zones/db.mydomain.com.zone.apple

mydomain.com. IN TXT "v=spf1 ip:64.251.168.218 ip:64.251.168.220 ~all"
www IN A 64.251.168.218
mail.mydomain.com. IN A 64.251.168.220
mail.mydomain.com. IN TXT "v=spf1 a ~all"
xserve.mydomain.com. IN A 64.251.168.218
xserve.mydomain.com. IN TXT "v=spf1 a ~all"
ns IN A 64.251.168.218
ns1 IN A 64.251.168.220
mydomain.com. IN MX 10 mail.mydomain.com.
... where xserve.mydomain.com is my machine's hostname.
I have a funky setup for DNS because I don't have a different, or second, DNS server (just the one on my Xserve with everything else) and my name servers are under this zone. I added the two IPs for my mail and hostname to the base SPF record. Someone could still spoof from using the name or www domains (same IPs) but I can check for it using Postfix up front. I also added "v=spf1 a ~all" in case another mail server tries to check the mailing server or hostname directly.
You'll usually want to set a TXT "v=spf1 ~all" (SPF null) for any records that have no possibility for mail origins, like your ftp and mobile, but it appears you also have a similar issue to me - those services will be running under the same IPs as the mail service. This is why I added "v=spf1 a ~all" to all essential services (mail and hostname). I don't know what will happen if you add an SPF null to an unnecessary service that happens to also have the same IP. (Will the IP get blocked in a cache during a lookup??) So I didn't add an SPF TXT to those domains. I'm a little confused at this point. I should probably read more about it.
http://www.openspf.org/FAQ/Common_mistakes
Also, you'll notice I added FQDN to mail and xserve. If I do this and ensure they are in my reverse DNS PTR records then I've seen that when I add new zone records with same IPs (like for another domain) then the PTR records don't keep switching to the newest entry (why does it do that?).
I don't think your use of the . in the CNAME records is correct. I think the CNAME records are probably unnecessary since you have already fully defined the domains in A records. Also, those A records probably don't need FQDNs (with the ending .). I only added mine for the reason noted above, concerning the PTR records.
I hope someone who knows some more than I can chime in on this.

I have an iMac, Mac Mini and a Macbook Pro connected to a Airport Extreme Base Station. I normally use a Public DNS Server and I am not sure where to put the DNS URLs. Do I put them on the individual computers or is there somewhere in the Airport Extreme Base Station that they go? where ever they belong please provide location and instructions. Thanks.
Configuring the AirPort Extreme with the DNS makes it so that you do not have to configure each individual computer on the WLAN, the DNS settings will be handed down to the devices when they are given their internal IPs, but as long as the base station does not have a competing/conflicting DNS setup, configuring each individual device, as suggested by Carolyn, works also.
However, something strange can happen sometimes when you use a public DNS setup. I use the one Carolyn suggests, OpenDNS, but I cannot access any of the webpages of my ISP with this configuration. I have Todo en Uno (All in One), a service that provides cable, telephone and internet service from my local cable company, CableVisión. So with the OpenDNS setup I cannot configure the digital options for my telephone service, such as blocking and unblocking Int'l long Distance calls. I have to remove the OpenDNS setting to do so. But I created a work around using Locations in the Network settings. I have one Location with my ISP's DNS settings and another Location with OpenDNS settings. I can quickly switch between the two when I need to access my ISP's website.

Server 2012 X64 R2 DNS Server keeps shutting down after inplace upgrade from Server 2012 X64
Hi,
ever since upgrading from Server 2012 X64 to Server 2012 R2 X64 my dns server keeps shutting down every several minutes before having to do a restart. When viewing the event log this is all I see..
The DNS Server service terminated unexpectedly. It has done this 497 time(s). The following corrective action will be taken in 60000 milliseconds: Restart the service.
if I look in the Application Error Log, I will also find the following:

I have tried removing and then reinstalling the DNS Server role, but the same situation occurs..
thanks,Hi,
I'm going crazy, I've upgraded my Server 2012 Standard to Server 2012 R2 Standard and now my DNS server keeps crashing since the in place upgrade. I have finally narrowed it down to it only crashes after several minutes if I load the data from
a file instead of the registry. As a test I:
-1- killed all my dns data,
-2- uninstalled the dns server role
-3- deleted the /windows/system32/dns directory
-4- reinstalled the DNS server role
-5- used the wizard to create a DNS server and a forward zone.
everything works okay, no crashes, then I change the advanced propertied of the DNS server to load from file, restart the DNS server and once again it crashes every 2 minutes..
Please help, this is killing me..
thanks in advance.. -
DNS Server settings not working as expected ....?
Greetings
I have our load balancer/firewall setup to where if someone enters a hostname like (www.example.com) it points it to a local server at 10.0.1.2
When logged into the network, the DNS Server that pulls up is 10.0.1.1 (IP of firewall), which is fine, but I also have the two openDNS servers at the 2nd and 3rd slots manually entered.
If the opendns servers are listed, the ping returns the public IP of www.example.com, but if removed, it does the right thing and pings the internal IP address.
Even though the 10.0.1.1 DNS server setting is first, it doesn't seem to use that setting when you have DNS servers entered manually.... any idea why and how to make this stop?
I prefer to leave the opendns settings in the DNS server settings (for when I'm switching around to various networks) ...Quick update. Added to a previously filed bug. Looks like it's assigned now so maybe we'll see a fix for this soon.

Install 11gr2 RAC, dose all IP needs to go in DNS server or just 3 scan ip
Hello,
I am bulding a brand new 2 node RAC cluster (11gR2). But i know this new version has some big changes with the scan. My question is, do all the IP needs to be in a DNS server or just the 3 IP related to the scan ??
So do i need to put in 2 public, 2 private, 2 VIP, 3 scan ip (all 9 of them) in the DNS or just the 3 scan ip ???it depends. If you decide to use GNS then no but it you want to do manual configuration of the oracle network portion then yes. (Personally I would suggest do so just as a fallback but that's just me).
the following from the install guide explains it best:
1.2.4 Overview of Network Connection Requirements
The following is an overview of network configuration requirements for Grid Naming Service (GNS) in a Grid Plug and Play configuration, and manual network configuration. Network administrators and system administrators can refer to the Preinstallation chapter in Oracle Grid Infrastructure Installation Guide for your platform for detailed configuration information.
The network configuration for Oracle Clusterware and Oracle RAC requires several addresses. The following is a list of those addresses:
GNS virtual IP address (GNS installations only): A static IP address configured in the GNS. The GNS virtual IP listener forwards queries to nodes in the subdomain on the cluster managed by GNS.
Within the subdomain, the GNS uses multicast Domain Name Service (mDNS) to enable the cluster to map hostnames and IP addresses dynamically as nodes are added and removed from the cluster, without requiring additional host configuration in the DNS.
To enable GNS, you must have your network administrator provide a set of IP addresses for a subdomain assigned to the cluster (for example, grid.example.com), and forward DNS requests for that subdomain to the GNS virtual IP address for the cluster, which GNS will serve.
Single Client Access Name (SCAN): A domain name that resolves to all the addresses allocated for the SCAN. Oracle recommends that you allocate three addresses to the SCAN. During Oracle Grid Infrastructure installation, listeners are created for each of the SCAN addresses, and Oracle Clusterware controls which server responds to a SCAN address request.
For high availability, you should provide at least three IP addresses in the DNS to use for SCAN mapping for high availability. A SCAN domain name must be unique within your corporate network.
Virtual IP address: A public internet protocol (IP) address for each node, to be used as the Virtual IP address (VIP) for client connections. If a node fails, then Oracle Clusterware fails over the VIP address to an available node.
During installation, if you do not use Grid Naming Service (which provides the VIP automatically), you provide VIP addresses. The VIP for each node is associated with the same interface name on every node that is part of your cluster. If you have a domain name server (DNS), then your network administrator should register the host names for the VIP with the DNS, so that it is resolvable from any client, as well as the cluster nodes. The VIP should not be in use at the time of the installation, because this is an IP address that Oracle Clusterware manages.
Public IP address: A public host name address for each node, assigned by GNS, or assigned by the system administrator during initial system configuration for manual configurations. The public IP address name must be resolvable to the hostname. Register both the public IP and the VIP address with the DNS. If you do not have a DNS, then you must make sure that both public IP addresses are in the node /etc/hosts file (for all cluster nodes).
Private IP address: A private IP address for each node to serve as the private interconnect address, dedicated exclusively to internode cluster communication. GNS configures the address automatically. If you select manual configuration, then you must ensure that the following is true for each private IP address:
o
It must be separate from the public network
o
It must be accessible on the same network interface on each node
o
It must be connected to a network switch between the nodes for the private network; crosscable interconnects are not supported
The private interconnect is used for internode communication by both Oracle Clusterware and Oracle RAC. If you use manual configuration, then the private IP address must be available in each node's /etc/hosts file. Oracle recommends that it is configured on a dedicated switch (or switches) that are not connected to anything other than the nodes in the same cluster.
Note:
All host names must conform to the RFC 952 standard, which permits alphanumeric characters. Host names using underscores ("_") are not allowed. -
I need clarify if my understanding of DNS and Open Directory pertaining to OS X Server, in this case an Xserve still running Panther. I've had DNS and OD running for a couple of years now on an all Mac network(and our IS dept provides only minimal support, no user support...you get the idea). We get DNS from company servers, and I had zone records added to these servers in order to get everything up and running from my end. Now my IS dept is scanning our network for services that don't meet policy. Well my Xserve shows as a running DNS server.
So, finally to my questions. Don't I need the DNS service running on the Xserve for the OD service to function? The IS contact who brought this to my attention seems to think I should be able to turn off my DNS service, since their servers have the forward and reverse lookups.
Years back, after I knew the lookups were on there servers I added the zones to my DNS (thinking I was doing things right). So I have both an A and a PTR record on my server. Do I just remove these, stop the service, and OD will keep on ticking?
Thanks"Don't I need the DNS service running on the Xserve for the OD service to function? The IS contact who brought this to my attention seems to think I should be able to turn off my DNS service, since their servers have the forward and reverse lookups."
He's right, you don't need to run DNS in OS X.
You just need to use any DNS with the correct settings for your server IP/name forward and reverse.
