Thad, Before getting to your questions, I want to define two terms as 'I' understand them.
Disaster Recovery - The ability to have a system available at another SITE in case the primary site becomes unavailable because of a disaster. This is typically done as a 'standby' operation, and the two are not necessarily online at the same time, typically with separate DB servers with log shipping or some other replication technology to get your data over to the DR site High Availability - The ability to have more than one host serving the same purpose simultaneously so that if one goes offline, the other is still able to service requests. I think what you are discussing below is high availability.mostly because you are talking about a server group.which is where two remedy servers connect to the same DB..DR requires significantly more setup, configuration and maintenance..now, onto your questions Server-Name - your first 3 bullets are correct.your 4th, kinda.$SERVER$ automatically tacks on the domain of the server, but essentially correct Server-Connect-Name --1 - Not necessarily.in my server groups I have another alias configured for this one --2 - True --3 - Also true Q - Which of the above values are used for AR paths in the file system A - Neither. The names above are solely for clients connecting to them.having nothing to do with the install directories. When you install Remedy, it defaults to putting it into the directory that you specified as your 'server name' during the install.so depending on how you have your things configured during install, it could be either of the names above, or none of them.but it's actually irrelevant because nothing uses that specifically to connect Q - Email engine configuration (EmailDaemon.properties): Same question, which value is used? A - Typically, as far as I understand, each ARServer will have its own email engine (at least that's the way we have it configured).so the individual nodes of your 'clients' should point to that node's name IP-Name - This is useful in ANY server configuration.you should have ANY permeation of names that someone could use to connect to your server added in here so that the server recognizes 'that name' as 'me' Here is our config, we have two nodes with a load balancer. We also have several load balanced web servers Web -Load Balanced name: application -Node1 Name: application-node1 -Node2 Name: application-node2 This allows us to utilize the load balancer to re-direct to our clients HA configuration. Each web node is pointed to the Load balanced server group alias App -Load Balanced name: application-app -Node1 Name: application-app1 -Node2 Name: application-app2 Again.this allows a client to connect to either the HA name, or each individual node, and using an alias for the Server-Connect-Name makes it so that later you could move servers (in an upgrade situation) without re-configuring everything (we are moving from 2003 virtual servers to 2008 virtual servers, and won't need to re-configure a lot of the infrastructure because they all point to the alias J In the configuration above, the Server-Name is the Load Balanced one.the Server-Connect-Name is the alias for that node. Email, etc uses the node specific name. From: Action Request System discussion list(ARSList) [mailto:[email protected]] On Behalf Of Thad Esser Sent: Monday, December 12, 2011 4:47 PM To: [email protected] Subject: Server name clarification ** Hi all, I'm finally back to working on my disaster recovery server configuration, after a six month diversion for other projects. Having never worked in an environment where the Remedy server name was different than the host name, and after some intial reading, I had a couple of configuration questions that I figure the arslist could clarify the fastest. My current understanding of the following ar.conf settings (please correct anything that needs it): Server-Name: - The name that remedy knows itself by, and which users would use to connect to the system. - Must be DNS-resolvable. - In a server group, all servers in the group have this set to the same value. - It is the value returned by the $\SERVER$ keyword (that's a guess...?) Server-Connect-Name: - The actual host name of the server that Remedy lives on. - Must also be DNS-resolvable. - In a server group, each server will have its individual host name configured here. Questions: Which of the above values are used for AR paths in the file system. Directories for things like the email engine, AIE, and /etc/arsystem/<servername> all have the server name in them. Do those represent the "Server-Name" or the host name? Email engine configuration (EmailDaemon.properties): Same question, which value is used? Thinking through this, it would make the most sense that all those settings would use the Server-Name, not the host-name? If that's not true, what are the exceptions? I'm sure I'll have more questions (IP-Name and Map-IP-Address look fun), but these are the ones pestering me now.
