At the end of my installation I received the follwing error message:

I am hoping that this looks familiar to some of you on here and you can help me resolve.

When I try to start the listener I get the following.

[oracle@jhlinux db_1]$ lsnrctl status

I found a thread that reported a similar issue and was directed to Oracle Support Document 353843.1 . The suggestion was to adjust the /etc/hosts file, but I don't see anything wrong in the file:

[oracle@jhlinux etc]$ cat hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
# ::1 localhost6.localdomain6
127.0.0.1 localhost.localdomain localhost
192.168.1.254 jhlinux.home.com jhlinux




Please advise. Thank you in advance for your help.

The problem is with OS/Networking mis-configuration
Oracle is the victim; not the culprit.
The fix is some change to OS.
Consult Installation Guide for what you neglected to do prior to starting Oracle installation.

I think I may have found what is wrong but I want to be sure:

[oracle@jhlinux ~]$ cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
# ::1 localhost6.localdomain6
127.0.0.1 localhost.localdomain localhost
192.168.1.74 jhlinux.home.com jhlinux

[oracle@jhlinux ~]$ nslookup jhlinux.home.com
Server: 192.168.1.254
Address: 192.168.1.254#53

Name: jhlinux.home.com
Address: 192.168.1.74

[oracle@jhlinux ~]$

It seems like the ip is not matching but which one should I change ?

They look the same to me.
>192.168.1.74 jhlinux.home.com jhlinux
>Address: 192.168.1.74

bcm@bcm-laptop:~$ oerr tns 512
00512, 00000, "Address already in use"
// *Cause: Specified listener address is already being used.
// *Action: Start your listener with an unused address.

I read above as saying another listener is already running on your system

Please explain to me what the following is for ?

Server: 192.168.1.254
Address: 192.168.1.254#53

as opposed to

>192.168.1.74 jhlinux.home.com jhlinux
>Address: 192.168.1.74

I am thinking the former is DNS and the latter is host. My understanding is that they should match.
Please correct me if I am wrong and advise.

How come yours nslookup is showing Address: 127.0.0.1

whereas I have that ip in /etc/hosts but not showing in nslookup ?

I am confused as my latest listener status is as follows

[oracle@jhlinux ~]$ lsnrctl status

Hi

This problem can also be a result of ipv6 being enabled on your linux machine (assuming you have looked at /etc/hosts and /etc/services for port allocation conflicts) - most recent linux distributions enable ipv6 by default which can be a cause the port allocation code to fail when no ipv6 network is being used.

To see if ipv6 is enabled in your kernel run the following on your command prompt

> ip a | grep inet6

If you need to disable ipv6 in your kernel you should either
blacklist your ipv6 module - or if compiled directly in your kernel, disable ipv6 via sysctl.

eg:

add the following into /etc/modprobe.d/blacklist.conf
blacklist ipv6

AND/OR

add the following into /etc/sysctl.conf
net.ipv6.conf.all.disable_ipv6 = 1
(exec: sbin/sysctl -p)

(I would boot your machine to ensure the changes take hold - or restart appropriate services in /etc/init.d)

Finally after your reboot make sure ipv6 is actually disabled:
> ip a | grep inet6
(should return nothing)

clean up your old oracle installation including /etc/oratab and /etc/oraInst.loc

- remove ipv6 address from /etc/hosts to be extra sure - you can restore these later.

and restart your oracle 11g installation.


(please google for distribution specific ways to disable ipv6 - if ipv6 is still enabled after the above changes)

After adding suggested entry in /etc/sysctl.conf


[root@jhlinux etc]# grep ipv6 sysctl.conf
net.ipv6.conf.all.disable_ipv6 = 1



[root@jhlinux etc]# /sbin/sysctl -p
net.ipv4.ip_forward = 0
net.ipv4.conf.default.rp_filter = 1
net.ipv4.conf.default.accept_source_route = 0
error: "net.ipv6.conf.all.disable_ipv6" is an unknown key
kernel.sysrq = 0
kernel.core_uses_pid = 1
net.ipv4.tcp_syncookies = 1
kernel.msgmnb = 65536
kernel.msgmax = 65536
kernel.shmmax = 68719476736
kernel.shmall = 4294967296
[root@jhlinux etc]# ip a | grep inet6
inet6 ::1/128 scope host
inet6 fe80::200:6cff:feed:9fc5/64 scope link
[root@jhlinux etc]#
