In my previous post we took a quick look into one of the SQL Server features that I personally consider to be a great boon to any DBA, the Dynamic Management Views and Functions. Im going to show you through some basic examples on how you can use these views to get meaningful information out of your SQL Server instances.
I was migrating some old databases (I’ll write some more about this later) couple nights back to new database server and while that went mostly alright, things were not looking so good in the morning. I was driving on a highway, taking my daughter to daycare when the phone rang. I did recognize the number being that of my customer, so I answered.
I’ve been working with SQL Server ever since 1999, back then it was the 6.5 version which was soon replaced by the SQL Server 2000 (we skipped the 7.0 completely). Back in those days getting information out of SQL Server was much, much more difficult and you had way less tools for it. Then came the SQL Server 2005 and suddenly there was a plenty of information available to make troubleshooting and working on performance issues so much easier.
In fact there’s so much information available these days, that finding out where simply to start can be a daunting task. When I first started working with SQL Server 2005 my first task was to familiarize myself with the new feature called Dynamic Management Views and Functions, or DMV’s as they’re sometimes called. In SQL Server 2005 you have about 90 DMV’s, in SQL Server 2012 the number of DMV’s is almost 180. They’re definately an important tool in any DBA’s toolkit. And that is what this article is about, to get yourself started with the DMV’s.
