  • You probably have enough

    - by BuckWoody
    This a decidedly non-technical post, and even a little preachy. I post it here because you, the technical professional, are the perfect audience for it. I have enough stuff. I never think so, of course, but I do. I don’t consider myself rich, but if you have a comfortable place to sleep,  enough food to eat and you can plan for your future, you are rich. And when we are rich enough to have “enough” stuff, that usually means we have too much stuff. Stuff costs money that could be put to better use, stuff needs painting, cleaning, fueling, feeding, storage and caring for. Stuff is a burden. So I decided a few years back that I had enough stuff. We gave away a lot of things, and we don’t buy any new (meaning we didn’t have one before)  things – only replacement things. We’d rather “do something” than “have something”. But even so, when birthdays, anniversaries and Christmas rolled around, we got more stuff. So I asked all of my friends and relatives to do something for me.   I ask folks that want to give me a gift (for whatever reason) to donate the price they would have paid for the gift to a charity they care about. This does a few things: They have to find a charity to care about The fact that I made it through a calendar year now actually means something Someone else gets the help they need Everybody feels better No, I’m not saying these things so you’ll think I’m a wonderful person - the reason I’m posting this here is that as a technical professional you probably have enough stuff like I do. So I ask you to try this out. Try it for one birthday, or one Holiday, or even for a year. I can promise this: it will change your life, the life of the person who gives the gift, and the person’s life who receives it. If you do try it, I’d love to have a comment here on your thoughts.

  • Wait Statistics in Microsoft SQL Server

    - by KKline
    When it comes to troubleshooting in relational databases, there's no better place to start than wait statistics. In a nutshell, a wait statistic is an internal counter that tells you how long the database spent waiting for a particular resource, activity, or process. Since wait statistics are categorized by type, one look will quickly tell the variety of problem that needs your attention, assuming you know meaning for Microsoft's lingo for each wait type....(read more)

  • Chapter One - Concepts/Requirements (The Fundamentals)

    - by drsql
    So here we are, the starting chapter with the obligatory introductory material that I hope people will read, digest, memorize and really take to heart.  I also realize that that is pretty unlikely. In fact, the first two chapters are kind of like that. First I introduce concepts, and in the next chapter I show how to draw pretty pictures of those concepts. Then comes normalization and after that we really start doing some modeling. In this chapter I am going to cover the basic stuff that you...(read more)

  • Presenting Beginning PowerShell at SQL Saturday 149 MN

    - by merrillaldrich
    I am happy to be presenting a session on beginning PowerShell for DBAs at my new home town’s SQL Saturday! (I moved from Seattle to Saint Paul, MN a short time ago.) I will be sharpening this presentation up to make sure anyone who comes will not go away empty handed. BTW, WOW, the schedule is up and I must admit I did not expect nine tracks of awesome. This looks amazing. My session is geared toward helping those DBAs who have not seen PowerShell, or perhaps may find PowerShell syntax opaque or...(read more)

  • Speaking at Houston Techfest on September 8

    - by John Paul Cook
    I’m giving my talk on SQL Server and SSMS Tips and Tricks at Houston Techfest on September 8, 2012. It will be similar to the one I gave at last year’s Techfest and also the one I gave at the Houston SQL Server User Group meeting last month. It will be mostly different from the one I gave at the last SQL Saturday in Houston. I will cover regular expressions. If you bring your laptop with you, you can follow along with me to make sure you leave able to actually use regular expressions. If you are...(read more)

  • Backup and the evil RETAINDAYS option

    - by TiborKaraszi
    "So what bad has this option done?", you probably as yourself. Well, not much, but I find it evil because it confuses people, especially those new to SQL Server. I have many times seen people specifying something like 3, and expect SQL Server to keep the three most recent backups in the backup file and overwrite everything which is older than that. Well, that is not what the option does. But before we go into details, let's look at an example backup command which is using this option: BACKUP DATABASE...(read more)

  • DTLoggedExec 1.0.0.2 Released

    - by Davide Mauri
    These last days has been full of work and the next days, up until the end of july, will follow the same ultra-busy scheme. This makes the improvement of DTLoggedExec a little bit slower than what I desire, but nonetheless Friday I’ve been able to relase an updated version of the tool that fixes a bug and add a very convenient option to make even more straightforward the creationg of execution logs: [bugfix] Fixed a bug that prevented loading packages from SSIS Package Store [new] Added support for {filename} placeholder in both Data Flow Profiling and CSV Log Provider The added feature allow to generate DataFlow profile logs and CSV logs that has the same name of the package that generated them, es: DTLoggedExec.exec /FILE:”MyPackage.dtsx” /LPA:"FILE=C:\Log\{filename}_{date}_{time}.dtsCSVLog" Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

  • New Project Starting. Got Gas?

    - by merrillaldrich
    “Storage is just like gasoline,” said a fellow DBA at the office the other day. This DBA, Mike is his name, is one of the smartest people I know, so I pressed him, in my subtle and erudite way, to elaborate. “Um, whut?” I said. “Yeah. Now that everything is shared – VMs or consolidated SQL Servers and shared storage – if you want to do a big project, like, say, drive to Vegas, you better fill the car with gas. Drive back and forth to work every day? Gas. Same for storage.” This was a light-bulb-above-my-head...(read more)

  • PASS Summit Preconference and Sessions

    - by Davide Mauri
    I’m very pleased to announce that I’ll be delivering a Pre-Conference at PASS Summit 2012. I’ll speak about Business Intelligence again (as I did in 2010) but this time I’ll focus only on Data Warehouse, since it’s big topic even alone. I’ll discuss not only what is a Data Warehouse, how it can be modeled and built, but also how it’s development can be approached using and Agile approach, bringing the experience I gathered in this field. Building the Agile Data Warehouse with SQL Server 2012 http://www.sqlpass.org/summit/2012/Sessions/SessionDetails.aspx?sid=2821 I’m sure you’ll like it, especially if you’re starting to create a BI Solution and you’re wondering what is a Data Warehouse, if it is still useful nowadays that everyone talks about Self-Service BI and In-Memory databases, and what’s the correct path to follow in order to have a successful project up and running. Beside this Preconference, I’ll also deliver a regular session, this time related to database administration, monitoring and tuning: DMVs: Power in Your Hands http://www.sqlpass.org/summit/2012/Sessions/SessionDetails.aspx?sid=3204 Here we’ll dive into the most useful DMVs, so that you’ll see how that can help in everyday management in order to discover, understand and optimze you SQL Server installation, from the server itself to the single query.

  • Brute Force Hardware versus Tuning

    - by jchang
    Every now and then, the question is asked “When will servers be powerful enough that performance tuning will not be necessary.” Sometimes I get the impression this was posed not on technical grounds, but rather that ISVs and CIOs don’t like performance specialists. Fortunately (for me) it does not appear that this will ever happen for two principal reasons: 1) hardware and tuning contribute in such completely different aspects that neither can be ignored, and 2) multi-core processors actually introduce...(read more)

  • Parameterize Charts using Excel Slicers in PowerPivot

    - by Marco Russo (SQLBI)
    One new nice feature of Excel 2010 is the Slicer. Usually, slicers are used to filter data in a PivotTable. But they might be also useful to parameterize an algorithm or a chart! We discussed this technique in our book , but Alberto Ferrari wrote a post that shows how to use this technique to allow the user to select two stocks that should be compared in an Excel Chart – as you might imagine, this will work also when you will publish the workbook on SharePoint! This is the result: Nice to see that...(read more)

  • Utility Objects–Waitfor Delay Coordinator (SQL Server 2008+)

    - by drsql
    Finally… took longer than I had expected when I wrote this a while back, but I had to move my website and get DNS moved before I could post code… When I write code, I do my best to test that code in as many ways as necessary. One of the last types of tests that is necessary is concurrency testing. Concurrency testing is one of the most difficult types of testing because it takes running multiple processes simultaneously and making sure that you get the correct answers multiple times. This is really...(read more)

  • Shakespeare and storing Unicode characters

    - by John Paul Cook
    This post is about the political issues involved with using multiple languages in a global organization and how to troubleshoot the technical details. The CHAR and VARCHAR data types are NOT suitable for global data. Some people still cling to CHAR and VARCHAR justifying their use by truthfully saying that they only take up half the space of NCHAR and NVARCHAR data types. But you’ll never be able to store Chinese, Korean, Greek, Japanese, Arabic, or many other languages unless you use NCHAR and NVARCHAR...(read more)

  • Upgrades from Beta or CTP SQL Server Software is NOT Supported

    - by BuckWoody
    As of this writing, SQL Server 2008 R2 has released, and just like every release, I get e-mails and calls from folks with this question: “Can I upgrade from Customer Technical Preview (CTP) x or Beta #x or Release Candidate (RC) to the “Released to Manufacturing” (RTM) version?” No. Right up until the last minute, things are changing in the code – and you want that to happen. Our internal testing runs right up until the second we lock down for release, and we watch the CTP/RC/Beta reports to make sure there are no show-stoppers, and fix what we find. And it’s not just “big” changes you need to worry about – a simple change in one line of code can have a massive effect. I know, I know – you’ve possibly upgraded an RC or CTP to the RTM version and it worked “just fine”. But hear this tale: I’ve dealt with someone who faced this exact situation in SQL Server 2008. They upgraded (which is clearly prohibited in the documentation) from a CTP to the RTM version over a year ago. Everything was working fine. But then…one day they had an issue. Couldn’t fix it themselves, we took a look, days went by, and we finally had to call in the big guns for support. Turns out, the upgrade was the problem. So we had to come up with some elaborate schemes to get the system migrated over while they were in production. This was painful for everyone involved. So the answer is still no. Just don’t do it. There is one caveat to this story – if you are a “TAP” customer (you’ll know if you are), we help you move from the CTP products to RTM, but that’s a special case that we track carefully and send along special instructions and tools to help you along. That level of effort isn’t possible on a large scale, so it’s not just a magic tool that we run to upgrade from CTP to RTM. So again, unless you’re a TAP customer, it’s a no-no.

  • TPC-H Benchmarks on SQL Server 2014 with Columnstore

    - by jchang
    Three TPC-H benchmark results were published in April of this year at SQL Server 2014 launch, where the new updateable columnstore feature was used. SQL Server 2012 had non-updateable columnstore that required the base table to exist in rowstore form. This was not used in the one published TPC-H benchmark result on SQL Server 2012, which includes two refresh stored procedures, one inserting rows, the second deleting rows. It is possible that the TPC-H rules do not allow a view to union two tables?...(read more)

  • Developing a Support Plan for Cloud Applications

    - by BuckWoody
    Last week I blogged about developing a High-Availability plan. The specifics of a given plan aren't as simple as "Step 1, then Step 2" because in a hybrid environment (which most of us have) the situation changes the requirements. There are those that look for simple "template" solutions, but unless you settle on a single vendor and a single way of doing things, that's not really viable. The same holds true for support. As I've mentioned before, I'm not fond of the term "cloud", and would rather use the tem "Distributed Computing". That being said, more people understand the former, so I'll just use that for now. What I mean by Distributed Computing is leveraging another system or setup to perform all or some of a computing function. If this definition holds true, then you're essentially creating a partnership with a vendor to run some of your IT - whether that be IaaS, PaaS or SaaS, or more often, a mix. In your on-premises systems, you're the first and sometimes only line of support. That changes when you bring in a Cloud vendor. For Windows Azure, we have plans for support that you can pay for if you like. http://www.windowsazure.com/en-us/support/plans/ You're not off the hook entirely, however. You still need to create a plan to support your users in their applications, especially for the parts you control. The last thing they want to hear is "That's vendor X's problem - you'll have to call them." I find that this is often the last thing the architects think about in a solution. It's fine to put off the support question prior to deployment, but I would hold off on calling it "production" until you have that plan in place. There are lots of examples, like this one: http://www.va-interactive.com/inbusiness/editorial/sales/ibt/customer.html some of which are technology-specific. Once again, this is an "it depends" kind of approach. While it would be nice if there was just something in a box we could buy, it just doesn't work that way in a hybrid system. You have to know your options and apply them appropriately.

  • Keeping your options open in a cloud solution

    - by BuckWoody
    In on-premises solutions we have the full range of options open for a given computing solution – but we don’t always take advantage of them, for multiple reasons. Data goes in a Relational Database Management System, files go on a share, and e-mail goes to the Exchange server. Over time, vendors (including ourselves) add in functionality to one product that allow non-standard use of the platform. For example, SQL Server (and Oracle, and others) allow large binary storage in or through the system – something not originally intended for an RDBMS to handle. There are certainly times when this makes sense, of course, but often these platform hammers turn every problem into a nail. It can make us “lazy” in our design – we sometimes don’t take the time to learn another architecture because the one we’ve spent so much time with can handle what we want to do. But there’s a distinct danger here. In nature, when a population shares too many of the same traits, it can cause a complete collapse if a situation exploits a weakness shared by that population. The same is true with not using the righttool for the job in a computing environment. Your company or organization depends on your knowledge as a professional to select the best mix of supportable, flexible, cost-effective technologies to solve their problems, whether you’re in an architect role or not.  So take some time today to learn something new. The way I do this is to select a given problem, and try to solve it with a technology I’m not familiar with. For instance – create a Purchase Order system in Excel, then in Hadoop or MongoDB, or even in flat-files using PowerShell as an interface. No, I’m not suggesting any of these architectures are the proper way to solve the PO problem, but taking something concrete that you know well and applying that meta-knowledge to another platform will assist you in exercising the “little grey cells” and help you and your organization understand what is open to you. And of course you can do all of this on-premises – but my recommendation is to check out a cloud platform (my suggestion would of course be Windows Azure :) ) and try it there. Most providers (including Microsoft) provide free time to do that.

  • Do you know your DNS server?

    - by John Paul Cook
    If you don’t know your DNS server is valid, you need to find out before July 9. The FBI found rogue DNS servers and replaced them with clean, safe DNS servers to protect the public. These safe, clean servers will be turned off on July 9, 2012. If your computer was compromised to use the rogue servers, it will stop resolving DNS queries on July 9 when the clean servers are turned off. The FBI has provided full technical details at http://www.fbi.gov/news/stories/2011/november/malware_110911/DNS-changer-malware.pdf...(read more)
