Adam Kreul | Blog

I am currently a Senior DBA for Integrys Energy Services in Green Bay, WI. I’ve been a DBA since 2008 and have worked primarily with SQL Server versions 2005 and above supporting databases as large as 6TB.

Although my title says “DBA”, I also play the role of SAN administrator and data warehouse developer. I love learning and applying new technology and have a passion for making the environment I support as fast as possible. My blog is syndicated from www.adamkreul.com and you can follow me on Twitter at @AdamKreul.

I recently was involved in a discussion about whether or not to enable the ‘Optimize for Ad Hoc Workloads’ server configuration setting.  My initial thought was to leave it disabled, since this is the default after all, and we didn’t have a specific situation where it was believed enabling this… Read more

Better Together: Reduced Run Time and I/O

The run-time metric gets all the love, and for good reason.  It’s easily witnessed by end users and the one management cares about.  When DBAs have the task of cutting down the run time of a query, this typically starts in a non production environment, consisting of different server architecture… Read more

Use the WordPress Revision Counter to Keep Shipping Posts

I haven’t been at this blogging thing an extremely long time, and I certainly haven’t been as consistent as I’ve wanted to (working hard on this though – at least one post a week!).  There is no getting around it – blogging is time consuming.  Especially technical blogging.  My first… Read more

Combating the CXPacket Wait Type

Often, when DBAs are looking at total wait statistics on the servers they manage, CXPacket is at or near the top of the list.  If this is the case for you as well, chances are your server isn’t on fire, but there could be room for improvement.

Making Sense of PCIe SSD Use with SQL Server

When Fusion IO burst onto the scene in 2007, offering a PCIe card that was said to be able to achieve 100,000 IOPS, the IT world went wild.  While Fusion IO certainly is a pioneer in the PCIe SSD space, this technology has come a long way in its short… Read more

Database Maintenance Plans: A Primer

Databases and newborns have a lot in common.  They both require constant care.  They both require constant monitoring.  They also may both puke on you in the middle of the night.  Unlike newborns, however, you can set up automated maintenance plans for databases.  If you’re starting a new gig as… Read more

Why I’m Not Excited About Hekaton (In-Memory OLTP)

A while back I had written a post about why I’m excited about Hekaton (now called ‘In-Memory OLTP’ – not sure why, Hekaton is much more fun to say), and while I am certainly still excited about this new feature, it does have some significant barriers to entry.  Here’s a… Read more
