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
Last week, I took the 70-461: Querying Microsoft SQL Server 2012 exam. I decided recently to try and achieve getting my MCSE: Data Platform certification within the next six months. Taking this exam was step one, and now I have four remaining. Rather than spending a bunch of money on… Read more
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
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
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.

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
Imagine this scenario: One of your servers just crashed, and you open a ticket with Microsoft for them to perform a root cause analysis and hopefully find a solution. What you get instead is this: “Unfortunately, all we were able to capture was a mini dump that doesn’t provide us… Read more
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
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
In one of SQL Server Central’s recent daily newsletters, Steve Jones’s editorial was inquiring whether or not anyone has been using the CLR (common language runtime) integration within SQL Server. Recently, a change in a business process dictated that we needed to delete over 3 billion rows from a 16… Read more
If you work in IT, the office becomes your second home. It’s where we make a living, and most of us take a lot of pride in the work we do. We feel good when we’ve put in a successful day at the office, however we also have those days…
I’m just a little late to the party, but no time like the present, right? I plan to be very active responding to #sqlhelp requests, and will be posting my latest blog posts. I would greatly appreciate a follow (@AdamKreul), and would be happy to return the favor! Read more
That guy or gal over there going on and on about spindles and IOPS – that’s your SAN admin. For the sake of your SQL Server environment, you two need to develop a solid relationship. Here’s some basic SAN lingo to get you started:
LUN is an acronym for… Read more
If you administer a SQL Server Reporting Services server, chances are you’ve had users complain the report manager is loading slow. You go out the report manager to investigate, and it loads normally. You have the end user try again, and this time it works fine for them too. You… Read more
I recently read Microsoft’s research paper on Hekaton, the new in-memory database engine in SQL Server 2014. When I first heard about it, I was pretty excited, but after reading the deep dive specs, I’m ecstatic. I highly recommend checking out the research paper in its entirety, but… Read more
Partitioning is a feature that has been around since SQL Server 2005. It allows for users to split a table across multiple filegroups. Multiple filegroups means the opportunity to store a table across multiple volumes. If you have a SAN that has disk tiers, you can use partitioning to store… Read more
