Hello all,

I am trying to install Oracle 9i on my Linux Red Hat Enterprise 3 Server (WS Edition). That is right, WS edition (not ES or AS). I don't know if any one of you has done this before ????

Anyway, I am running into host IP configuration issues. To get a better understanding of the problem I need to run the nslookup command. Problem is, that when I do this is what I get:

1) nslookup
(Note nslookup is deprecated and may be removed from future releases consider using the 'dig' or 'host' programs instead. Run nslookup with the '-sil ent' option to prevent this message from appearing.)

I tried using the 'dig command, but I don't understand the output or how to use it. The dig gives me a parts a QUESTION, ANSWER and ADDITIONAL SECTIONS.

How can I use these commands to resolve my problem ?
Any ideas ?

PT

Use host ;)


Cheers,
Tink

Hello again,

Typing some commands, this is what I get:

1) hostname
Linux2005

2) cat /etc/hosts
cat /etc/hosts
# Do not remove the following line, or various programs
# that require network funcitonality will fail.
127.0.0.1 localhost.localdomain localhost

3) nslookup Linux2005
...
Server: 192.9.200.80
Address: 192.9.200.80#53

** server can't find Linux2005: NXDOMAIN

4) host -l Linux2005
;; Connection to 192.9.200.80#53(192.9.200.80) for Linux2005 failed: connection refused.
host -v Linux2005
Trying "Linux2005"
Host Linux2005 not found: 3(NXDOMAIN)
Received 102 bytes from 192.9.200.80#53 in 187 ms

PS: I am getting error messages such as 'Thrown when the IP address of a host cannot be determined' Pop-Up error messages. How can I go about to resolve this issue ?

probably your hostname is defined in /etc/sysconfig/network, like this:
HOSTNAME=linux2005

some programs search your hostname to connect. if your hostname is not defined, probably like this programs or daemons cannot work. your hostname is not defined in /etc/hosts file.

i advice u to change your /etc/hosts file this:
127.0.0.1 linux2005 localhost.localdomain localhost

let me know if it fixed.

Hello,

Should I consider adding an entry to the file as follows:

192.9.200.80 Linux2005

following the first line ??

PT

u can do. but the software u installed will try to connect to 192.9.200.80 instead of loopback. i dont think it is good idea. loopback is better idea.

if u r sure about 192.2.200.80, u can do it like that :-)
127.0.0.1 localhost.localdomain localhost
192.9.200.80 Linux2005

good luck.

Hello,

During the installation of one of the Oracle 9i components, I get an error message as follows:

The Agent Configuration Assistant gave: No value for the NODEINFO + Starting HTTP Server gave a message: (Error resolving hostname: localhost).

Are these error messages also concerned with the /etc/host file ? Is there something else I should be looking at ?

PT

im not familiar to oracle. i just know about networking a little

do u have localhost entry in hosts file?
maybe it tres to resolve localhost through nameserver. u can try to run named (bind). named has localhost entries by the default. and change /etc/resolv.conf to use your local nameserver.

[root@teknik root]# cat /etc/resolv.conf
search localhost
nameserver 127.0.0.1

pleaze chow me Edit file resolv.conf or any file in Redhat 9?
