Installing a Loopback adapter without a Domain Name

Im trying to install the microsoft loopback adapter for the oracle 10g database. In one of the steps I was supposed to configure the "hosts" file within the driver directory of the windows folder.
Below is the precise directions... I dont have a domain name, I just have a internet service that gives me a dynamic IP address... what do I do?
Add a line to the SYSTEM_DRIVE:\WINDOWS\system32\drivers\etc\hosts file with the following format, after the localhost line:
IP_address hostname.domainname hostname
where:
IP_address is the non-routable IP address you entered in step 16.
hostname is the name of the computer.
domainname is the name of the domain.
For example:
10.10.10.10 mycomputer.mydomain.com mycomputer

Make one up.
Or not.
The domain name in the /etc/hosts is optional.
Since you use /etc/hosts, you are not using a DNS server for that specific interpretation. Therefore you can use whatever you want. I'd use something like 'glomph.tst' just so I can have thje joy of typing that in the browser URL box.

I got a warning for local area connection 2, it says that my pc does not have a IP address assigned, and its status is : limited or no connectivity .
I tried to repair to establish the full connection by clicking on the repair button, but the process is failed.

I don't have a fixed IP, however my IP is seldom changed. And I'm ok with 127.0.0.1

i am installing oracle 10g on windows xp proffessional + AMD sempron 3100+
when started oracle universal installer, i received a warning like following :
DHCP configuration detected , you need to configure ur primary loopback adapter to MICROSOFT LOOPBACK ADAPTER
i m using belkin wireless card to connect to internet and i dont need to change it anyway.
please someone suggest me : whether i shud continue with this warning OR do i need something more before installing oracle 10g ???
thanks in advance,
-imranmca

I have Windows XP professional SP2 with a static ip address of my internal lan.
The installation don't pass the check about lan with the same message as you
"DHCP configuration detected , you need to configure ur primary loopback adapter to MICROSOFT LOOPBACK ADAPTER". Why?
I followed the instructions and now is all working adding in the hosts file 2 lines and not only one:
IP_addr computer_name.domain computer_name
IP_addr sid_name.domain sid_name
I'm not convinced of my euristic solution... can someone explain me why i have to configure the microsoft loopback adapter when i don't have a dhcp configuration?

How to I get my iWeb website online without a domain name and using iCloud or .mac....

I want to publish my iweb website online. Since we no longer have mobile me do I use icloud, and if so how do I do it?

No, you don't and you can't do it because iCloud does not offer any web hosting facilities, so if you want to publish your website online, you'll need to go to a web host and register a domain name along with a web hosting account. Take a look at http://www.godaddy.com and http://www.hostexcellence.com. Both these companies offer domain name registration as well as hosting accounts and there are lots of others too.

INSTALL[for load] command without Security Domain AID

Hello all,
I have a question for the INSTALL[for load] command.
The Security Domain AID is optional field, so I'm wondering if I didn't specify the AID, then which Security Domain performs the INSTALL[for load] command?
Thanks,
Julie.

Which ever one you are sending your APDU commands to. Which SD did you select ? Usually, the default applet is the ISD, so the commands are going to that applet.

Installing loopback adapter

How can I configure if I have a DHCP computer? Is it necessary to install a loopback adapter in order to install oracle database?What should I write in SYSTEM_DRIVE:\WINDOWS\system32\drivers\etc\hosts if I don't have a domain?
Thanks

Oracle has a listener component that listens on the network for requests coming to a specific machine for a specific database service. It loads that machine name at install time.
The database service locks the machine's name and attempts to register the service to the listener.
If later your machine name or IP changes because the DHCP lease has been renewed under a different name, the database will attempt to register with a listener osomewhere else ... kind-a useless.
Such is the life of a server - for security and performance, things tend to be statically defined, for example in the ...\etc\hosts file. But users with desktops and laptops prefer convenience to security and performance.
The almost-happy compromise is to install the loopback adapter, allowing the listener and the database server to have a static 'local' address.
You are free to create your own domain ... jim13.home will work as well as any other, allowing your database to be 'orcl.jim13.home' and you machine to be 'mycomputer.jim13.home'

10g Install - Loopback Adapter

I am trying to install 10g on windows 2000.
But installation is failing at:
Network congifuration requirements failed : Because system has DHCP assigned.
I tried setting the loopback adapter in order to install. Editied the file SYSTEM_DRIVE:\WINDOWS\system32\drivers\etc\hosts
to include :
123.13.123.12 name.domain.com name
But again its failing with the same error.
I checked the previous post in forum but still everywhere its the same solution given.
Is there anything i am missing?

The Oracle Installation Guide for Windows has an entire section on installing a loopback adapter with instructions that are specific to your version of Windows.

Domain Name for Install

I don't have a domain name on my laptop, only a workgroup name. Is it
possible to install iAS without a domain name, and if not, can I make-up a
domain name or how should I work around this issue? Thanks in advance!

I mentioned this many times before. This is not the windows
domain/workgroup. You do not need it for iAS to work.
Domain means DNS, so you need to put something into for your DNS suffix.
And yes, you can use any valid DNS type entry, like mydomain.com

Domain Names and Oracle

Hi,
I am preparing to install Oracle 8i on my Windows NT machine,
and I stumped into something that I can find no answer for.
Oracle asks me to say what my domain name is (e.g. suse.com). It
uses this to manage the different Oracle instances, e.g.,
server1.suse.com and server2.suse.com. Well, the problem is that
our machines do not have our domain name. That is, the machine I
am using (as well as all our servers) does not have a DNS name
xxx.intelsystech.com. Their names are managed by our ISP, and
for all I know they change it once in a while. Our machines do
have unique IP numbers, though (e.g. 43.25.44.32). We have
managed to do just about everything else using these fixed IP
numbers (e.g. ftp, http, etc.). Also, names are not a problem
because all machines are in the Windows Active Directory domain,
and therefore have a "local" name (e.g. Monet) in the Windows
LAN.
What should I enter when Oracle asks for my domain name? And for
the machine name? Can I use the IP number? Or the IP pattern
(e.g. 43.25.44.)? How will I be able to refer to an Oracle
service (listener, database name) without a domain name?
Thanks,
Taha

Oracle asks me to say what my domain name is (e.g. suse.com). It
uses this to manage the different Oracle instances, e.g.,
server1.suse.com and server2.suse.com. These domain names are not the same as ip domain names. You need
the domain names only if you want to have different oracle db's
connected to each other, e.g. for replication.
If you are using this db alone, then just choose any name.
How will I be able to refer to an Oracle
service (listener, database name) without a domain name? You can use ip-addresses for listener and tnsnames, but it is
better to use dns-names.
Hop this helps.

How to configue "Microsoft Loopback Adapter" ?

Hi,
I have Oracle 11GR1,Win XP. with DHCP enabled.
My conputer gets dynamic IP on connection to internet, so i want to install "*Microsoft Loopback Adapter*".
For that i visited this link:
http://download.oracle.com/docs/cd/B1930601/install.102/b14316/reqs.htm#BABGHEFB_
There, in section 2.4.5.3, Installing a Loopback Adapter on Windows 2003 or Windows XP,
step 20,they said to edit host file.
In this step i have some confusion:
>For example:
>10.10.10.10 mycomputer.mydomain.com mycomputer
What to write in above line in place of mydomain.com ?In above example mycomputer is the computer name.In my case
my computer name is user-5ef511de5
so , i wrote
10.10.10.10 user-5ef511de5 user-5ef511de5
This gave unexpected behaviour. That i was unable to connect on DB through any tool.
Please tell what exactly to write in that host file ?
My computer in standalone computer that frequently gets connected to internet via dial up connection.

You may try this:
1. Make a static entry in listener for your database
or
2. Wait for sometime, so that pmon automatically registers the instance with listener
or
3. fire the command: sqlplus > alter system register;

Microsoft Loopback Adapter ping failed

I have a laptop and a desktop both running XP Pro SP2. I followed the instructions to install Microsoft Loopback adapter as part of the Oracle installation.
On the desktop, I successfully installed Microsoft Loopback adapter. I was able to ping the IP and host name of the loopback adapter and everything works fine.
On the laptop, I installed the Microsoft Loopback adapter. I cannot ping the Microsoft loopback adapter's host or IP. I can ping localhost and external internet hosts/IP.
Any ideas?

Madrid,
Thank you very much for your help. On my laptop, I have Norton Internet Security (NIS) and there was a firewall rule blocking the traffic.
This problem is now resolved.
Thanks for your help, Madrid.

Domain name settings - Newbie question

Sorry for a newbie question!
I am already pointing a domain name to web hosting for email account. Now, I need an application server to run ERP software and Oracle, and installing Solaris and Oracle need a domain name.
If I point my domain name to the server, how do I receive emails from web hosting???
Install an email server to the application server instead? What can I do if I want the same domain name? Any option?

Setting up a mailserver and making sure it doesn't suddenly turn into a spambox is not something you do with the use of a few commands. I suggest to dive into the Solaris admin guide on docs.sun.com and read up on e-mail and network services.
If that is asking too much of your time you'll be better off getting your ISP to handle all this for you.

Your questions are completely off-topic for the forum.
These SunOS forums are for questions on <i>"how do I install my OS"</i>
You particular question is in the <i>"how can I install Solaris while using the CD drive"</i> forum.
So, if you had a question on how to edit the /etc/inet/hosts file to establish a FQDN on the computer, then it might be appropriate for the forum.
Unfortunately, I don't have a clue on where to redirect you, except perhaps to the Sun Java Enterprise System suite of applications?
