Usually get this if there is something amiss with the db-config.php - if you want to pop it up I can take a look - remember to mask / change any usernames / passwords

That means that you haven't added the server your running on as a dc (the 3 numbers of the IP address you've put in your add_dc_ip doesn't correlate with the current servers IP address).
The lhost line suggests you have some empty strings where there should be ip address in your add_db_server lines.

email it to barry at incsub dot com and it'll come direct - let me know the ip address of your webserver and db-server (if they're the same then just let me know the one).

Hi, I get the same warning. PHP Notice: Use of undefined constant DATACENTER - assumed 'DATACENTER' in /sitepathwp-content/db.php on line 287
I think this is besause the define( 'DATACENTER', $dc ); is inside in a if statement (line 106 -110), which doesn't get true and so the DATACENTER is not defined.
I think there should be a define for DATACENTER right on top of the db.php like the global functions but I'm not sure that the correct value should be. define( 'DATACENTER', false); or define( 'DATACENTER', null);
Can you inform the plugin developer to guide us about it?

You need to add a add_dc_ip with the IP setting for the IP address where your webserver is, this will then pass the IF statement you have mentioned and the define will be set.

Hey there.
Last time I saw that error a fresh set of files did the trick:
http://premium.wpmudev.org/forums/topic/error-messages-from-wp-after-installing-multi-db
And a similar one here:
http://premium.wpmudev.org/forums/topic/oh-what-have-i-done-this-time
Does a fresh set resolve anything?
Take care.

Hi Tim, yes I try to set up and the previous warnings fixed, but I'm getting this message since edit it.
Anyway, I'm looking for solution. If I can fix it, I'll write here.
Support Chimp (joined March 2010) Likes (0)
I'll ask Barry as well to see if he has any further pointers which might help.
Thanks.

I've read your post http://premium.wpmudev.org/forums/topic/oh-what-have-i-done-this-time#post-254338 and made some changes.
I just checked error-logs and get this.

but our database server in the same dc? and I defined 3 numbers of ip as a dc.
I've used this tool ( http://premium.wpmudev.org/db-tools/db_servers.php ) for create db servers value, I don't think so.
Can I send smilar copy of our db-config file via contact form?

Greetings Mustafa,
Just chiming in since I found this ticket in the back and I do a lot of multi db installs.
For that item please try putting in just the first three octets of the IP i.e. xxx.xxx.xxx.
However, I checked two of my running flawlessly installs of Multi DB and use this:
add_dc_ip('localhost', 'dc1');Please advise.
Cheers, Joe

Awesome! I was having the same error and I had put all 4 octets in the dc ip address instead of 3 octets. Now all is fine.
