VIP is getting conflict


Dear Linux Expeerts,

Virtual IP(vip) for node 2 is mismatching on node2.
Please see VIP address of node2 (rac2-vip)

>> /etc/hosts on both nodes

PHP Code:
# cat /etc/hosts 
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1       localhost.localdomain localhost
#::1            localhost6.localdomain6 localhost6

### PUBLIC
192.168.212.40   rac1   rac1.oracle.com
192.168.212.41   rac2   rac2
.oracle.com

### PRIVATE
192.168.10.1     rac1-priv
192.168.10.2     rac2
-priv

### VIRTUAL
192.168.212.50    rac1-vip
192.168.212.51    rac2
-vip

Again, you need to read the LQ Rules about text-speak and not using it; it's "please" not "pls". And you have been asking about Oracle and networking configuration for a while now:
https://www.linuxquestions.org/quest...ac-4175618004/
https://www.linuxquestions.org/quest...se-4175613124/
https://www.linuxquestions.org/quest...eq-4175610987/
https://www.linuxquestions.org/quest...-x-4175594517/
https://www.linuxquestions.org/quest...es-4175607240/
https://www.linuxquestions.org/quest...db-4175602653/

Again, you say you are an Oracle DBA. Complete instructions on how to install Oracle RAC are (AGAIN) available on Oracle's website. AGAIN, the very first hit in Google for "how to install and configure oracle rac" is: https://docs.oracle.com/cd/B28359_01...c.htm#TDPRC003

If you want to change the IP addresses on your systems, great; go change them. Use the exact same method as you did to assign the addresses in the first place. You (again) don't tell us what version/distro of Linux you're using or what kind of hardware, but you're probably talking about the unpatched/unupdated RHEL that you're not paying for on VirtualBox again?

I don't feel that all the referenced, former questions are duplicates of this question. Rather than make observations about former posts, please deal with the one question. If it is a duplicate, recommend people do not respond and instead click Report, while citing the duplicate question as part of the report. Then moderators can evaluate this clearly and close any duplicates.

The question is unclear. The image offered does not show a problem related to an IP address conflict problem.

The question seems to be asking how to configure an IP address for a particular node on an interface.

What I can say is that in the link provided as part of TB0ne's answer, you can eventually get to a section providing aid for how to configure the Ethernet. It would also seem that this set of documentation has been reviewed by you because much of the actions you're performing here are exactly what the recommended steps to take show.

Meanwhile the point being made here is that you've configured that node address for a static IP as of now and you wish to change it. Therefore please take the time to review the documentation and review how you accomplished this previously.

Or is this an incorrect assessment of your question?

Apologies, I did not mean to imply they were duplicates, but rather all centered around one topic (how to install Oracle/Oracle RAC). While there may be 1,000 steps to install a certain program for instance, opening 1,000 different threads that only differ slightly from each other is onerous. Especially when someone who is ostensibly experienced in installing this software has the complete set of documentation available to them, which details the 1,000 steps.

Agreed.

Correct TB0ne. It is a good point that not all the formerly cited questions are duplicates. I feel they do point out prior experience with related subjects.

Similar to my comment about duplicate questions, it also should be noted that if members continually post questions following a pattern which is not enabling LQ members to aid them and showing a reluctance to follow up on their threads, the same recommendation applies which is to report these behaviors. This will enable the site admins to point to a history when considering next actions.

At present, it will be helpful to see feedback from Joystick regarding a better clarification of this problem as well as things attempted to resolve this.
