DBTA – Delayed Durability—The SQL Server 2014 Transaction Log Hack!

Originally appearing in my monthly column at Database Trends & Applications magazine. Delayed durability was announced late in the SQL Server 2014 development cycle, but offers something that many SQL Server professionals have wanted for years—the ability to disable transaction logging. Why turn off the transaction log? It is the main guarantor of transactional consistency in SQL Server and is critical for highly recoverable applications, after all. That answer, in itself, tells you about situations where you might like to turn off the transaction log. That is, you can accelerate … [Read more...]

DBTA – Russian Hackers Steal 1.2b Internet Credentials: Or, Why the Heck Does this Keep Happening?!

I'm decidedly old-school in a few of my habits. My morning routine, barring anything out of the ordinary, is one such example. Typically, I'll get up between 6:30 to 7:00 am, grab my first cup of coffee, and then chat with my daughters for a few minutes before seeing them off to school. Next, I make a bowl of oatmeal (a great choice for diabetics like me), pour a second cup of coffee, and browse the local paper, The Tennessean, while I have breakfast. On the morning of August 5, I had the added pleasure of spewing said coffee and oatmeal all over my morning paper when I read the headlines: … [Read more...]

DBTA – 6 Reasons to Think About Upgrading to SQL Server 2014

  If you’re an IT manager, the first thing I’d like to tell you is how invested Microsoft is in SQL Server. While earlier incarnations of executive leadership focused in other areas (anyone remember “Developers! Developers! Developers!”?), Microsoft’s new leadership is very bullish on SQL Server. And, why not? After Microsoft Office and Windows Server, SQL Server is Microsoft’s third biggest money-making product line. Check out the recording of the “Accelerate your insights” webcast, about SQL Server 2014, featuring appearances by CEO Satya Nadella, COO Kevin Turner and CVP Quentin … [Read more...]

Third Party Applications and Other Acts of Violence Against Your SQL Server

I just got finished reading a great blog post from my buddy, Thomas LaRock (t | b), in which he describes a useful personal policy he used to track changes made to his SQL Servers when installing third-party products. Note that I'm talking about line-of-business applications here - your inventory management systems and help desk ticketing apps. I'm not talking about monitoring and tuning applications since they, by their very nature, need a different sort of access to your back-end server resources. (Full disclosure: both Tom and I currently work for different tools vendors. But we're both … [Read more...]
