setting hostname,domainname and static IP address

Hi,

I have an issue regarding hostname and domainname on Oracle Linux 5.4.

I followed the steps given on this link for Oracle Linux 5.4 installation.

http://www.oracle-base.com/articles/linux/OracleEnterpriseLinux5Installation.php

As per the snapshots and guidelines given on this link,I should have been asked to configure network interface.
But It didn't show me the screens shown in steps 16,17 and 18 where I could have entered hostname,domainname,IP etc.

And when I checked after installation,it showed me

hostname
localhost.localdomain

and

domainname
(none)

That's because it took DHCP network configuration automatically(Correct me if i am wrong!!).
Although I am going to turn it's currnet DHCP assigneed IP into static IP.

Now,as I am going to have to install Oracle E-Business suite on this platform,I must have hostname,domainname and IP set properly.

Please guide me how I can set these three things(hostname,domainname and IP) permenantly.
Also should I turn its current DHCP IP into static IP before changing hostname and domainname or after it?

Thanks,
Rushi

    4)service network restart



    2)settipng up hostname & ipconfig

    steps

    ipaddreddss hostname.domain name hostname


    save & exit

    ex:

    192.168.0.12 apps.oracle.com apps



    2) service network restart

    3) chk hostname -i (ip address)

    hostname -a (hostname)

    Correct.
    Please guide me how I can set these three things(hostname,domainname and IP) permenantly.
    Please check the steps above, it should be helpful.
    Also should I turn its current DHCP IP into static IP before changing hostname and domainname or after it?
    It does not matter, just make sure you have configured static IP Address and you have proper entry in the hosts file.

    Like I mentioned in my first post of this thread,the screens where I would have entered these details did not appear.

    So,will making changes to /etc/hosts and /etc/sysconfig/network files only be equivalent to supplying hostname,domainname and IP information during installation?(I am a bit too concerned about this thing because I don't want it to create any issues during or after Oracle EBS 12.1.1 installation)

    Thanks,

    You will have to set up a static IP Address as mentioned above (Setup > eth0 > edit an enter the IP Address).

    Do I need to make changes to /etc/sysconfig/network-scripts/ifcfg-eth0 file?
    Currently it is showing

    BOOTPROTO=dhcp
    ONBOOT=yes

    If you change it from the front end, then it is not required. However, please see the values in (Figure 3-1) in this link for the values you should have -- http://www.linuxhomenetworking.com/wiki/index.php/Quick_HOWTO_:_Ch03_:_Linux_Networking
