Network configuration requirements 10g

hi every body
i am trying to install oracle 10 g db using Vmware on Centos 5.
i have performed all the steps as described in installation guides but when OUI is checking pre reqs it is giving this error
"checking network configuration requirements" and then "not executed"
can somebody please specify these requirements ???
in case i want to move forward it says that you can expect some problems during installation ???
thnx in advance .
Regards

do you have a network setup ? Can you ping other servers from the VM ?
You can run a database without a network. The listener configuration may fail, but you can easily re-run it later. You could just do the install, and see if anything else fails. If it does, the error may give more information.
Or you can turn off the check using
runInstaller -ignoreSysPrereqs

Oracle 10g Installtion error Network Configuration requirements ... failed

Checking Network Configuration requirements ...
Check complete. The overall result of this check is: Failed <<<<
Problem: The install has detected that the primary IP address of the system is DHCP-assigned.
Recommendation: Oracle supports installations on systems with DHCP-assigned IP addresses; However, before you can do this, you must configure the Microsoft LoopBack Adapter to be the primary network adapter on the system. See the Installation Guide for more details on installing the software on systems configured with DHCP.

Are you installing Oracle 10G R2? If this is the case then for DHCP network environments, you need to create a Microsoft loop back adapter.
Microsoft Loopback Adapter creation:
===========================
Step 1: Programs -> control panel -> Add Hardware.
Step 2: In the Add Hardware wizard. Click 'Next' and select 'Yes, I have already connected the hardware'. option and click on 'Next'.
Step 3: Select the last option 'Add a new hardware device' from the 'Installed hardware' window and click on 'Next'.
Step 4: Select the last option 'Install hardware that I manually select from the list (Advanced) and click on 'Next'.
Step 5: Select 'Network adapters' in 'Common hardware types' list and click on 'Next'.
Step 6: Where you can see 'Microsoft loopback adapter' on the right hand side of the frame.
Step 7: proceed with all default installation and then try installing Oracle.
I hope this will suffice.
Thanks

Error during Checking Network Configurations Requirements in RHEL3 VM

Hi,
I have a Red Hat Enterprise Linux Image Virtual Machine on my desktop which uses Fedora Linux. I have set this up using VMplayer.
I need to install Oracle 10g on the RHEL VM.
As the RHEL VM does not have X Windows, I am connecting to it from the Fedora Linux to do the installation.
During the Product-specific Prerequisite checks:
Checking Network Configurations Requirements throws an error,
Please find it below:
Actual Result: Unknown Host Exception has Occured :rhel3vm:rhel3vm
Check complete: The overall result of this check is: Not executed <<<<
Recommendations: Oracle supports installations on systems with DHCP-assigned public IP addresses. However, the primary network interface on the system should be configured with a static IP address in order for the Oracle software to function properly.
The Fedora Linux gets the IP address from the DHCP and allocates an IP address to the VM.
However, when we set both of them as static and the problem still persists, and also when we set the fedora as dynamic and RHEL VM as static, the issue is not resolved.
Any help will be truely appreciated. Thank you.

We were running a non-DHCP (static IP) configuration and ran into this issue. We discovered that the hostname and FQDN were not correctly specified in the /etc/hosts file.
Fixing the hosts file to correctly reference the IP resolved the issue.
Hope this helps...

Network Configuration requirements not executed, why?

During installation all checks are passed but this one, is there any particular reason for this check not to be executed? Should I worry over it not beein executed?

I'm trying to install Oracle 10g 2 on a Red Hat 4 server with a static IP.

Hi!
Either your machine is setup to use DHCP after all or the installer just has trouble to find the correct information.
Recheck the network settings of your machine (redhat-config-network).
Just ignore the warning and continue.

what can I do
tank you very much to help

I suggest you to read this thread: Re: I can't access to my Enterprise Manager. Then you'll realize why it is important to define a fixed IP Address and not to entirely rely on a DHCP dynamically assigned IP Address. This thread shows you how to configure a Loopback adapter to solve this issue.

My server runs on RHEL4. I have configured eth0 after installation of RHEL with a static IP and my server is not on network.
While installing the oracle10g R2 network configuration check is not executed. if i check the box and continue, installation is done without any error. After the installation when the server is connect to a network oracle is not accessible from a client machine.
PS: Listener is started and database is up.

Oracle 11g - Network Configuration check

Hi All,
This is my first time here and I am a newbie to Linux and Oracle installation.
I just finished installing Linux Enterprise version 5 ( provided by Oracle corp).
At the time of installation I did not do any type of network configuration and let the default network connection take effect.
After installing all the pre requirements for the Oracle 11g installation on my laptop I was stopped with a warning on the Oracle univesal Installer - product specific Prerequisite check.
This is what it gave me---
Checking Network Configuration requirements..
Check complete. The overall results of this check is : Not executed <<<
Recomendation : Oracle supports installation on systems with DHCP-assigned public IP addresses. However the primary network interface on the system should be configured with a Static IP Address in order for the oracle to function properly.See the installation guide for more details on installing the software on systems configured with DHCP.
I checked with the manuals and do not find any information about how to fix it.
The info given in the manual is
Installing on DHCP Computers
Dynamic Host Configuration Protocol (DHCP) assigns dynamic IP addresses on a network. Dynamic addressing enables a computer to have a different IP address each time it connects to the network. In some cases, the IP address can change while the computer is still connected. You can have a mixture of static and dynamic IP addressing in a DHCP system.
In a DHCP setup, the software tracks IP addresses, which simplifies network administration. This lets you add a new computer to the network without having to manually assign that computer a unique IP address.
Now i made some changes to the Network Config as root user and my Network configuration file looks like ( ie. /etc/hosts)
127.0.0.1 localhost StaticIP
It was previously something like
127.0.0.1 localhost.localdomain localhost.
As per the installation documents where ever i had references to localhost, i had left the localhost with the same name ' localhost' and have not changed it. Now it has StaticIP and I am not sure how to proceed.
What must I do?
I want to fix this error and also want oracle to work.
Thanks for your help!!

Thanks a lot guys to respond to this. I am using OEL5 ( supplied by Oracle Corp) and Oracle 11g. Installation of Linux takes about 40 minutes and installation of Oracle takes about an hour to 2 hours. Not sure why some RPM's do not show up on the CD's provided by Oracle.
So I tried to reinstall Linux . But the whole problem is, the Network Screens ( during installation) do not show up at all. It just skips that portion and goes to the Screen where there is the world Map and tells you to set up the time and date. I tried installing Linux many times and those Network configuration screens do not show up at all.
Here is my dilemma. After installing Oracle 11g, and immediately accessing the site https://localhost.localdomain:1158/em takes me into the OEM.
But after I shut down my machine and boot up again, I am unable to use the OEM's site https://localhost.localdomain:1158/em. Instead I get the message
===============================
Unable to Connect
Firefox can't establish a connection to the server at localhost.localdomain:1158
1. The site could be temporaily unavailable
2. If you are unable to load any pages, check your computer's network connection
3. If your computer is protected by firewall or proxy, make sure that firefox is permitted to access the Web.
===================================
I am thinking the problem is with 2. I do not have any firewall in my machine and i have also disbaled SELINUX.
I want to configure the computer so i can use the OEM in my Linux laptop.
My $ cat /etc/hosts gives
127.0.0.1 localhost.localdomain.
Please help me setup the Network so i can connect to 11g OEM.
And BTW this laptop is not even used to connect to the Internet.
Thanks

Your solution is
"See the Installation Guide for more details on installing the software on systems configured with DHCP"
That book is at http://tahiti.oracle.com and the steps you need are in Chapter 2 of the Installation Guide for Linux.
Now, I could assume this is Oracle 11gR2 and you are using Oracle Enterprise Linux 5 Update 4, but I won't. Assuming things gets me into trouble.

Installing oracle- Network Configuration

1) If the install is for learning, just ignore the warning.
2) If you want this VM client to communicate with other VM clients on the
same VMware server, change the VMware NIC to host-only and then use the
Linux system-config-network tool, edit the ethX definition to use your
chosen IP address; a manually-assigned IP address is static, thus
avoiding the warning.
3) If you want machines other than your laptop to be able to communicate with
your RDBMS, you need to do step #2 but change the VMware NIC emulation to a
bridged device.
Hope this gives you the right places to start looking.

How to configure Oracle 10g to use 4GB memory

I'm trying to configure Oracle 10g to use >4GB memory. Have configured server boot.ini with required flags (/3GB /PAE). Rebooted server then created standard database, then connected to db instance and changed oracle parameters DB_BLOCK_BUFFERS, USE_INDIRECT_DATA_BUFFERS as required. Restarted DB instance, DB fails to restarted with SGA memory error. According to oracle user docs the SGA is nolonger in effect due to previous settings. Can you provide example of SPFILE with parameters settings that do work and use >4GB memory. Current server has 8GB, 2 x Dual XEON core/processors (i.e. 8 processors)

The recommended /3GB switches in the boot.ini file can only be used with the following operating systems editions (KB article 291988):
Microsoft Windows 2000 Advanced Server
Microsoft Windows 2000 Data Center Server
Microsoft Windows Server 2003, Enterprise Edition
Microsoft Windows Server 2003, Data Center Edition
Microsoft Windows Small Business Server 2003
Important: Windows 2000 and 2003 Server Standard Editions DO NOT SUPPORT /3GB Switch.
So if your OS is listed above, then you cannot have a larger SGA.

How to configure Oracle 10g Advanced Security to use SSL concurrently with database User names and passwords
In Oracle Advanced Security Documentation it is mentioned that i can use SSL concurrently with DB user names and passwords. But when i configure the client certificate on the client my DB connection is getting authenticated using the certificate, which out passing user id or password.
We want to connect to Oracle DB over SSL channel so that the data packets are not in clear text. Also we want the user to make a connection using user id and password.
Basically we want SSL with out authentication.
