Vitaliy,
thanks for your article, very nice.

Can you please let me know what’s the difference between /etc/system and /project settings with respect to Oracle.

thank you,

Hi Vitaliy,

Finally i finished installation of oracle 10g on my redhat linux
I tried working with sqlplus, oem,isqlplus…everything works fine like before.

I realised problem was with misconfiguration of OS.

Thankyou very much for immediate response,
Anu

Hi Vitaliy,
I reinstalled linux and checked commands mentioned by you.
now everthing looks fine as u said..its shows

127.0.0.1 localhost.localdomain localhost

so i will try installing oracle now. i guess if it was this improper OS installation creating the problem, then now Oracle installation should be succesful. i will get back you to you ASAP about the progress.

thanks,
Anu.

@Anu

You should put the 127 address back into /etc/hosts — this is mandatory:

127.0.0.1 localhost.localdomain localhost

then add the actual IP and your hostname on the second line. Make sure the IP address is resolvable and assigned to your network interface:

After above changes are done you should bounce your box and verify your network is setup correctly:

ifconfig -a

Hi Vitaliy,
I apologise.
there was a typing mistake and now

[root@localhost ~]# cat /etc/hosts | grep `eval hostname`

192.168.0.1 localhost.localdomain localhost

works fine now.

but the installation problem remains same.

thank u,
Anu.

Hi Vitaliy,
Thankyou very much for immediate response.

yes i have checked as u mentioned above.everything was fine except this one

[root@localhost ~]# cat /etc/hosts | grep `eval hostname`

returns nothing whereas

[root@localhost ~]# cat /etc/hosts

192.168.0.1 localhost.localdomain localhost

i tried installation again..
@checking network configuration requirments it is not succeded and says oracle supports installation on systems with DHCP public IP address and i checked the logfile and it says
checking DetectifDHCPassignedIP …
…..
Actual result: java.lang.NullpointerException:Exception/error Occurred

SO removing static IP and making DHCP…will help? bcoz in windows wheni installed i just did that user verified and installation was fine without any problem and i can work on it.

Thanks,
Anu.

@Anu
Most likely yes, your issue is related to incorrect configuration of OS, specifically /etc/hosts.

Here is a typical run-check I do before install:

[root@qarac1 mail]# cat /etc/nsswitch.conf | grep hosts
#hosts:     db files ldap nis dns
hosts:      files dns
 
 
[root@qarac1 mail]# hostname
qarac1.mydomain.com
 
[root@qarac1 network-scripts]# cat /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=qarac1.mydomain.com
 
 
[root@qarac1 mail]# domainname
(none)
 
 
[root@qarac1 mail]# cat /etc/hosts | grep `eval hostname`
XXX.XXX.XX.XX   qarac1.mydomain.com   qarac1
 
 
[root@qarac1 mail]# more /etc/oraInst.loc
/etc/oraInst.loc: No such file or directory
