Question about RAC 10g on server running AIX and domain name changes

We have several 10g clusters running on IBM p-Series AIX servers, and our company is changing the domain name for our network. I am concerned that if we do not change the domain names in the TNSNAMES.ora file and also the /etc/hosts file on each server, the cluster will no longer function. We are using CRS (version 10.2.0.3) and ASM within each cluster.
Does anyone know where I can find information about changing the domain name that was set up as part of the CRS and database installs for RAC? Does anyone have experience doing this, and would be willing to share a few insights? Thanks in advance for any advice you can give!

You may be able to use the VIPCA utility for RAC to change or modify the public and private settings for your domain names on AIX. Also, the Oracle 10g DBCA "Database Configuration Assistant" should be of use to change your settings for your RAC environment.
Also, see here for a good IBM Redbook that covers Oracle 10g RAC on AIX platforms:

OS X Server clients can't login after IP renumber and domain Name change

I can not seem to get the logins working again on my OS X server (10.9.4 w/ server 3.1.2 on a 1 yr old. MacMini) after I needed to renumber the IP and change the domain name. I destroyed the Open Directory server, recreated it and created one test account. If I log in to the client with a local account I can connect to the server (Go>Connect To Server) from the client using my newly created account, but when I try to login to the server using the same network account login I get the "shaking head" response immediately. I have rebound the server to this client and it says that network accounts are available, but seem to be at a loss to understand why it won't let me login...
The only error message I see in any of the logs is the following:
(AFP Error Log:) Sep 15 20:21:47 isis.mydomain.com AppleFileServer[3032] <Info>: major error <1>: No credentials were supplied, or the credentials were unavailable or inaccessible.
I'm not sure what credentials it is referring to. I created a self signed certificate that I am using with OD, could that be the one?

Many Open Directory problems can be resolved by taking the following steps. Test after each one, and back up all data before making any changes.
1. The OD master must have a static IP address on the local network, not a dynamic address.
2. You must have a working DNS service, and the server's hostname must match its fully-qualified domain name. To confirm, select the server by name in the sidebar of the Server application window, then select the Overview tab. Click the Edit button on the Host Name line. On the Accessing your Server sheet, Domain Name should be selected. Change the Host Name, if necessary. The server must have at least a three-level name (e.g. "server.yourdomain.com"), and the name must not be in the ".local" top-level domain, which is reserved for Bonjour.
3. The primary DNS server used by the server must be 127.0.0.1 (that is, itself) unless you're using another server for internal DNS. The only DNS server set on the clients should be the internal one, which they should get from DHCP if applicable.
4. Follow these instructions to rebuild the Kerberos configuration on the master.
5. If you use authenticated binding, check the validity of the master's certificate. The common name must match the hostname and domain name. Deselecting and then reselecting the certificate in Server.app has been reported to have an effect in some cases. Otherwise delete all certificates and create new ones.
6. Unbind and then rebind the clients in the Users & Groups preference pane. Use the fully-qualified domain name of the master.
7. Reboot the master and the clients.
8. Don't log in to the server with a network user's account.
9. Disable any internal firewalls in use, including third-party "security" software.
10. If you've created any replica servers, delete them.
11. As a last resort, export all OD users. In the Open Directory pane of Server, delete the OD server. Then recreate it and import the users. Ensure that the UID's are in the 1001+ range.

Questions about RAC

I was reading the article about installing the RAC.
My conclussion , I can have till 127 instaces of a Oracle 10G database, working simultane. That is good really good and powerfull.
My questions
1º). ¿Can I have , by example, 3 , or any other number, of computer working with a HTMLDB instance or Oracle Aplication Server everyone serving pages to Internet and all then conect to one of those nodes? I think that yes, but prefer confirmation
2º) In case of failure of any of these nodes, broken computer ,by example, and I need to replace it, or I want add new nodes to a RAC system. ¿How I can do this? or ¿Where I can find documentation about this?
thanks for your help.

Is posting Question about RAC some kind of thought experiment on clustering? Like, if you post the same question several tyimes do you get faster answers?
Cheers, APC

Question about RAC and ASM

Hi,
We are thinking about build RAC using ASM for OEM database. It'll have two nodes, oracle 10g and Hitachi san with solaris ( or linux ). I've few questions about RAC and ASM.
1) Do I need to have ASM instance running on each node ? ( most likely yes... but want to make sure )
2) can I share oracle_home between ASM instance and database instance ? what is the best choice ?
3) I'm planning to use shared disks for all files, all databases.... what are the pros/cons ?
4) what should be the installation procedure ? Meaning, first create ASM instance on each node, then install cluster software, build RAC databases...... can someone explain..
5) I believe RMAN is the only option for backup since I'm using ASM, correct ?
I'm a newbie to RAC and ASM..
Thanks,

2) can I share oracle_home between ASM instance and database instance ? what is the best choice ?in 10g you can, in 11gr2 you cannot. and it might be better to seperate them because it will give you more flexibility with patching.
3) I'm planning to use shared disks for all files, all databases.... what are the pros/cons ?if you share your oracle_home you won't be able to do rolling updates. so i recommend to keep oracle_homes local.
4) what should be the installation procedure ? Meaning, first create ASM instance on each node, then install cluster software, build RAC databases...... can someone explain..follow the install guide for your respective version. for 10g you'd install clusterware first, then asm and database is last.
5) I believe RMAN is the only option for backup since I'm using ASM, correct ?pretty much. you could stop your database and dump the raw devices or use asmcmd/asmftp but rman is definitely the best choice

Some question about fade in // fade out by hideEffect and showEffect in Actionscript

Some question about fade in // fade out by hideEffect and
showEffect in Actionscript
Please kindly take a look at the following page:
http://camusmiu.no-ip.com/HounganQuestion/PictureHolderTest.html
(can view source)
I tried to make an image preloaded and scale the image to
it's preferred size.
When I came to consolidate the stuff into a component, I
found the application goes weird as I implementation the show/hide
effect.
The third trial which just hide and show the images directly,
instead of using viewstack, fail to bring the second image onto
screen.
It just used fadeOut instead of fadeIn(you see there is a
flash of the second image)
After some study of showEffect and hideEffect behaviour,
seems the mechanism of hide/show a component works in this way:
this._fadeIn:Fade = new Fade();
this._fadeIn.alphaFrom = 0;
this._fadeIn.alphaTo = 1;
this._fadeIn.duration = 1000;
this._fadeOut:Fade = new Fade();
this._fadeOut.alphaFrom = 1;
this._fadeOut.alphaTo = 0;
this._fadeOut.duration = 1000;
Component_A.visible = true;
Component_A.setStyle("showEffect", this._fadeIn);
Component_A.setStyle("hideEffect", this._fadeOut);
then when I set Component_A.visible = false, the sequence
works like following:
Component_A.visible = true
Component_A.visible = true, alpha = 100;
Component_A.visible = true, alpha = 50;
Component_A.visible = true, alpha = 0;
Component_A.visible = false;
The above sequence works visa versa as:
Component_A.visible = false;
Component_A.visible = true, alpha = 0;
Component_A.visible = true, alpha = 50;
Component_A.visible = true, alpha = 100;
Component_A.visible = true;
(Correct me if i am wrong)
========================================================================================== ====
From what I observe from the application, I have two
question.
1) When more than one component using the this._fadeIn,
this_fadeOut as the hide/show effects, the component in instance of
this._fadeIn? will it mess out if more than one component using the
fadeIn instance in the same time?
2) from the third component, i.e. PictureHolder3, when I load
other the picture , it fade out the new image instead of fading
in... Seems there is problem if I hide show too frequent. I think
when I hide then show right the way, the component only do the hide
part...
Can someone pls look into it and tell me what I did wrong?
Cuz in normal practice I don't think appropriate to use ViewStack
in Actionscript...

Hello Jack,
Currently, you can only import an swf file or you can embed videos from youtube, vimeo etc. into Muse / add HTML5 Video to Your Website.

How do I configure snow leopard server to allow local client to access the server using its public domain name

I have SLS 10.6 running on my local network with DNS configured.
I can access the server from a client on the lan using server.local or server.domain where domain name is my publically registered domain,
From the internet I can access my server using the registered domain name i.e. www.domain.com.
Is it possible to set my server up so that www.domain.com also reaches the server when used by a client locally? At present I get a page not found error.

The configuration you're aiming for is called split-horizon or split-brain DNS, and it's quite possible. It can get slightly hairy when you have different stuff using the same host name for different purposes, for instance, and you'll need to track all external DNS entries in your internal DNS server when you're running "split".
Here is how to set up DNS services. Split-horizon is one of the options listed there.
My preference is to use a different domain or subdomain within the network, and to avoid using split-horizon where I can reasonably manage it. One domain name is configured for and reachable outside and is effectively public, and the other domain (or a subdomain) is inside and private and only reachable directly or via VPN, for instance.

>how can I correct this alert?
Fix your DNS.
This non-fatal error is Apache's way of telling you that it can't work out the hostname of the machine it's running on.
It uses reverse DNS to determine this information. If you don't have a reverse DNS entry for your server's IP address, this is what you get.
Fix your DNS and the alert will go away, or just ignore it.

Please read my question carefully, this is, I think, a question for the experts. It's not the usual name change question.
When I setup my new MacBook Pro, something slipped by me and my computer was named First-Lasts-MacBook-Pro (using my real first and last name).
I changed the computer name in Preferences/Sharing to a new name and Preferences/Accounts to just be Mike. I can right click on my account name, choose advanced, and see that everything looks right.
However, If I do a scan of my network with my iPhone using the free version of IP Scanner, it lists my computer as First-Lasts-MacBook-Pro! And it lists the user as First-Last.
So even though another Mac just sees my new computer name, and my home folder is Mike, somewhere in the system the original setup with my full name is still stored. And it's available on a network scan. So my full name might show up at a coffee shop.
Can I fully change the name without doing a complete re-install of Lion and all my apps?

One thought... you said the iPhone displayed your computer's old name? I think that you must have used the iPhone with this computer before you changed the name. So no one else's iPhone should display your full name unless that iPhone had previously connected to your Mac. For example, I did this exact same change, and I use the Keynote Remote app to connect with my MacBook Pro. It would no longer link with my MacBook Pro under the old name, and I found that I had to unlink and then create a new link under the new name. So the answer to your question is, there is nothing you need to do on the Mac, but rather the phone, and no other phone will display your full name.

How to change the name / IP address and domain name for BOE Server

Hello,
We want to change the name / IP address and domain name for BOE Server, please could you indicate the steps or procedure to follow?
I need your help
thank you

If it's 3.1 just change them, shouldn't cause any issues if by domain name you are referring to changing the domain the computer belongs to. If you are changing your domain for AD authentication then you will may have to take quite a few steps if the old domain is going away. Let us know.
