SQL Server 2012 introduced AlwaysOn Availability Groups, a way to achieve high availability, disaster recovery, and scale-out reads. SQL 2014 brought some improvements around higher uptime and more scale-out, and all signs point to continued improvements in the next version of SQL Server, too. (I love it when Microsoft brings out features like this and continues to invest in them over time.)
A lot of the emails I get start with, “I’d like you to help me implement AlwaysOn AGs,” but it’s funny – most of the projects don’t end up actually deploying AGs. There’s a few barriers to adoption, and even when you’ve built an Availability Group, management can be a little tricky. Don’t get me wrong – I love the feature – but it comes with some surprises.
Rather than me prejudicing you, I’ll just put it out there as a question:
How would you change AlwaysOn Availability Groups?
Leave your answer in the comments. (And yes, Microsoft is watching.) Bonus points if you link to your Connect request.
We give away a lot of stuff – scripts, setup checklists, e-books, posters, you name it.
But we kept hearing a theme from folks: “Wow, I’ve seen one of your tools before, but I had no idea there were so many others!” In order to get everything, they had to go all over the place in our site.
To fix that, we’ve got a new easy button: our free SQL Server download pack. Now when you get anything, you’ll get everything in a single zip file, plus get email notifications whenever there’s a new version.
Enjoy, and hope we make your job suck just a little less.
We’ve added two new one-day pre-conference classes to our 2015 calendar:
SQLSaturday Boston Pre-Con: Developer’s Guide to SQL Server Performance – You’re stuck with a database server that’s not going fast enough. You’ve got a hunch that the biggest bottleneck is inside the database server somewhere, but where? In this one-day class, you’ll learn how to use powerful scripts to identify which queries are killing your server, what parts of the database server are holding you back, how to tackle indexing improvements, and how to identify query anti-patterns. The class is just $99 – learn more now.
SQLRally Nordic Copenhagen: Performance Tuning When You Can’t Fix Queries – Brent is flying over to Rally again! Here’s the abstract: Your users are frustrated because the app is too slow, but you can’t change the queries. Maybe it’s a third party app, or maybe you’re using generated code, or maybe you’re just not allowed to change it. Take heart – there’s still hope. Brent Ozar does this every week, and he’ll share his proven methodologies to performance tune with indexes, SQL Server configuration switches, and hardware. Learn more now.
Your users want Relativity to be up at all times. What’s the first step? How much work is involved? What will it all cost? I’ll give you a simple worksheet to get management and the IT team on the same page, and then show you how to turn those specs into a rough project plan and budget.
You’ll learn how to choose between different high-availability methods, and understand why clustering is such a no-brainer choice in this 22-minute video.
Got questions? Join us for our Tuesday Q&A webcast where I’ll answer your Relativity questions.
The latest version of our free SQL Server health check adds some nifty new stuff:
- Checks for non-default database configurations like enabling forced parameterization or delayed durability
- Looks in the default trace for long file growths or serious errors like memory dumps
- Checks Hekaton memory use and transaction errors
- Warns about database files on network shares or Azure storage
- Added the server name in the output if you enable @CheckServerInfo = 1
- Discontinued the Windows app version (was prohibitively expensive to get it into the Windows app store)
- And miscellaneous bug fixes and improvements
I love going on the RunAs Radio podcast because Richard Campbell is so much fun to talk to. In this show, we talk about the amazing new hardware that has come out lately for SQL Server. Dell and HP have brought out some amazing gear – support for 1.8″ SSDs, 64GB DIMMs, and more. The 2-socket server market is such an amazing space today.
You have a sneaking suspicion that your servers aren’t all paid for, and you need to get a rough idea of how SQL Server licensing works. You’ve never bought a box of SQL Server before, and you have no idea where to get started.
Microsoft Certified Master Brent Ozar will break it down into a few simple, easy-to-understand slides and show you the most popular licensing options. He’ll also explain 3 classic licensing mistakes and help you avoid ‘em in this 20-minute video.
To ask licensing questions after watching the video, join our weekly webcast for live Q&A. Not only do we answer your questions, we also give away a prize at 12:25 PM EST – don’t miss it!
Have questions? Feel free to leave a comment so we can discuss it on Tuesday!
What you need to do: log into SQLpass.org and change your password. If you use the same password anywhere else, change it on all of those sites immediately as well.
Why you need to do it: anytime you ever logged into SQLpass.org or SQLsaturday.com, or updated your password, or created an account, your password (along with everything else) went unencrypted between your computer and PASS’s web servers. Anyone sniffing network packets along the way saw your username, email, password, etc in clear text. (Think about what a security gold mine this would have been for someone sniffing WiFi at a SQLSaturday or the PASS Summit.) There’s a nice side benefit for updating your account – you also become eligible to vote in the current PASS elections.
Who you need to thank: the vulnerability was discovered by George Stocker on Friday, and PASS HQ finished the fixes & testing on Saturday. That’s a fantastic turnaround time – kudos to PASS for reacting so fast!
Who you should blame: yourself, for not noticing for years that you were putting login information into a web site that wasn’t using https. What kind of data professional are you, anyway? You’re probably even using that same password on multiple web sites, or heaven forbid, your company email. Get it together and use 1Password or LastPass.
Who you should not blame: the current PASS Board of Directors because this has likely been in place ever since PASS set up their current web site, and the current management inherited this little surprise. (You know how it goes – it’s like your ancient SQL Server 2000 in the corner where everybody knows the SA password.)
What’s still left to do: PASS needs to clearly, concisely communicate the severity of this issue to members as well – I really wish they’d set all passwords in the database to null, and force everybody to go through the password-reset process. The SSL setup still needs some work, as shown in the SSL tests, but considering the whole thing was done in 24 hours, it’s one heck of a good first step. (SQLsaturday.com also fails that test.)
Want to see our sessions in Seattle? Add all of our calendar events to our schedule:
Or if you’d rather add individual events:
Got a high performance SQL Server 2012 instance? Check out the brand new KB article for recommended updates and configuration options for SQL Server 2012 and SQL Server 2014 used with high-performance workloads.
Make sure you expand the following plus sign – this is where all the good stuff is stored:
After expanding it, you’ll get a huge list of categorized advice for trace flags, cumulative updates, MAXDOP settings, and much more:
I haven’t read through the details on this yet, but I’d note that this advice is focused on high performance workloads. Don’t go enabling trace flags without understanding what they do and their side effects.
I continue to be impressed by the documentation Microsoft is putting out. Books Online keeps getting better and better, and this is the coolest KB article I’ve seen in a long time. Way to go, Microsoft!
