Sametime cluster, what names have to match?


Tags :


Really this one is quite simple.  A cluster name is a placeholder for Sametime as well as Domino.  The Domino server and physical server name do not have to match.  Neither does the Sametime cluster and anything else.

Carl always says it best.  If you do not understand that FQDN matters in Sametime, then don't load Sametime.   Of course, I am paraphrasing there, but it is so true.  A Sametime cluster name does not get referenced except internally inside the server in stconfig.nsf.  You will use a virtual DNS entry for the cluster through some sort of load balancer.  A Domino cluster is for the clients and servers to find and talk to each other only.

I found that having some form of similar name matching for Domino clusters worked wonders to identify where the Sametime cluster resides.  Now is a Domino cluster required?  I would say that for vpuserinfo.nsf it is of course required.  How else would buddylist changes get pushed across.  If you are using LDAP then the directory is of no immediate importance so you are pointing to the same clustered source.  Admin4 won't process much since there are no name changes on the servers directly.

There you have it.  Then again my mind is like butter as I prepare for this week so I know that sounded (read) like a bit of ramble.
