You can also create CNAMES, which are aliases for existing A records. In an Active Directory domain, when a computer joins the domain it (almost always) gets a DNS record registered as well. If type in SQLSERVER-A in, say, SQL Server Management Studio to connect, what really happens behind the scenes is that hostname is checked against DNS for an IP address and then routed to the appropriate server.īut there’s more to DNS than A records. What we see here are A records, which is the most basic mapping of a hostname to an IP address. A Forward Lookup Zone is where most name resolution occurs when a computer requests a lookup. To see all the currently registered entries, we need to look at the Forward Lookup Zone. My DNS looks like this, which you can view in DNS manager: I have a copy of AdventureWorks2014 on SQLSERVER-A. I have a domain controller, a DNS server, and 3 computer objects in the domain: two SQL servers, and a user workstation. As a quick example, let’s look at my lab:

In a Windows Active Directory Domain, (almost) every PC on the network gets registered in DNS. And you can do that with the help of your network team and your local domain name system: DNS. So when databases move or you build a new server you not only need to ensure as little downtime as possible from a system perspective but with as little impact to a user’s system too. They each probably only care about one or two databases on a given instance, and depending on their release cycle even something as simple as changing a connection string might need to be a scheduled change. We mostly identify our servers by the hosts they run on.ĭevelopers and users, on the other hand, don’t always think like that. If I want to move a database from one server to another, or stand up a new server and move everything over to it, from now on I’ll need to make sure I type in the new host name. So for example, if the host name of my instance is SQLSERVER-A, then in my SSMS connection (or application) I probably type in a host name of fully qualified domain name (FQDN) of a server.

When you connect to a SQL Server instance, you’re most likely connecting directly to the host name of the server running that instance. Let me explain… When I move you move (just like that)

Plenty of times, this is where things fall down: it’s easy to build a server and install SQL Server on it, but once the server’s up, how do you ensure everyone is actually connecting to the right place? And most of all: how can you avoid unexpected downtime when you shut down the old server for the stragglers who didn’t update their connections? The solution is to make sure they don’t have to. What about your developers and customers who actually connect to and use the databases? Application developers need to update their connection strings to point to the new server, and your customers need to know the new server address as well. A checklist or runbook is almost always need to make sure you got everything, and it behooves you to do this in stages, starting with your test environments and moving up, slowly, towards your production systems.īut we’re looking at the process in terms of DBA work. Of course, that’s not always easy: in addition to moving your actual data to a new server, you have to worry about things like user permissions, linked servers, SSIS catalogs, agent jobs… the list goes on and on. While I’m passionate about some of those, the one that I fall firmly on one side of the fence on is upgrades: I always try to build a new server if I can. If you want a lively discussion among DBA’s, ask them their opinions on the following topics: using tbl_ and vw_ when naming objects, if SSMS should be installed on your servers, using mount points vs.
