Vertica Managament Console host domain name change

raulk89

Hi

vertica-console-11.1.1-0.x86_64

I have changed hostname for management console.
I can access MC with new URL, but my issue is that whenever I start up the MC, then I can see this old hostname in log files.

---

Please open the Vertica Management Console at https://vertica-mc.old.domain:5450/webui

Let's say, I have changed domain name to "new.domain".

Where and how can I change this setting..?

This should be set by system DNS at startup. Can you run "hostname -A" on the MC host and let us know whether the DNS name is old domain or new domain?

hostname -A
vertica-mc.new.domain

So all should be good. I have rebooted this MC host as well..

I have tried also:

grep -ri "vertica-mc.old.domain" /opt/vconsole/

And I only find log files there.

Ok, seems like all good now.

Before I had changed hostname from the actual MC host, and added new host record to DNS as well. So DNS had 2 records (both old and new).

vertica-mc.old.domain
vertica-mc.new.domain

And "hostname -A" gives all the names in round robin. So there may be times when during startup the "old.domain" name was picked.

I thought it will use host name instead of DNS names.

But yeah, when I remove the old.domain record, then all is good.

Thanks.

Also, can you confirm that the domain name change is the same for the single node vertica database host as well..?
Or there I need to do some additional tasks..?

E: For any of you wondering, usually there is no additional tasks needed to change vertica database OS hostname.
