  • Windows Not Sleeping All Night

    - by John Paul Cook
    Having a computer wake up when you don’t want it to wastes electricity and drains the battery on mobile devices. My desktop had been waking up at night, so I assumed it was some network traffic on my home network. I unchecked Allow this device to wake the computer on my network adapters . Figure 1. Network adapter Power Management tab. That didn’t solve the problem. I included the screen capture in Figure 1 because it could be part of the solution for someone else. To identify the root cause instead...(read more)

  • Problem identifying which page/page/function locks whole IIS server

    - by fnovak
    Hello, I have problem identifying which page/page/function locks whole IIS server. Out of the blue whole w3wp.exe jumps to CPU 90-98% usage. I have created 3 different application pools to see which w3wp.exe service locks the processor but I am unable to find out this information. I can only see that 2 of 3 services have 0-5% usage and one is jumping around 90-98% after some while. I think some process/function/redirect/sql is doing this but I would like to eliminate it. So far I am not even able to find the source of the problem. On my local development machine with VS2010 everything works like charm and I am unable to replicate problem. The server is windows 2k3 web server, sql server 2k5 and .net 4.0 Thank you for your help, links or any information on this issue. Fero

  • PowerPivot: Putting two stocks on the same PivotChart

    - by AlbertoFerrari
    In a previous post , I have used a stock exchange scenario to speak about how to compute moving averages in a complex scenario. Playing with the same scenario, I felt the need to compare two stocks on the same chart, choosing the stock names with a slicer. As always, a picture is worth a thousand words, the final result I want to achieve is something like this, where I am comparing Microsoft over Apple during the last 10 years. It is clear that I am not going to comment in any way why traders seem...(read more)

  • Session Evaluations

    - by BuckWoody
    I do a lot of public speaking. I write, teach, present and communicate at many levels. I love to do those things. And I love to get better at them. And one of the ways you get better at something is to get feedback on how you did. That being said, I have to confess that I really despise the “evaluations” I get at most venues. From college to technical events to other locations, at Microsoft and points in between, I find these things to be just shy of damaging, and most certainly useless. And it’s not always your fault. Ouch. That seems harsh. But let me ask you one question – and be as honest as you can with the answer – think about it first: “What is the point of a session evaluation?” I’m not saying there isn’t one. In fact, I think there’s a really important reason for them. In my mind, it’s really this: To make the speaker / next session better. Now, if you look at that, you can see right away that most session evals don’t accomplish this goal – not even a little. No, the way that they are worded and the way you (and I) fill them out, it’s more like the implied goal is this: Tell us how you liked this speaker / session. The current ones are for you, not for the speaker or the next person. It’s a popularity contest. Don’t get me wrong. I want to you have a good time. I want you to learn. I want (desperately, oh, please oh please) for you to like me. But in fact, that’s probably not why you went to the session / took the class / read that post. No, you want to learn, and to learn for a particular reason. Remember, I’m talking about college classes, sessions and other class environments here, not a general public event. Most – OK, all – session evaluations make you answer the second goal, not the first. Let’s see how: First, they don’t ask you why you’re there. They don’t ask you if you’re even qualified to evaluate the session or speaker. They don’t ask you how to make it better or keep it great. They use odd numeric scales that are meaningless. For instance, can someone really tell me the difference between a 100-level session and a 200-level one? Between a 400-level and a 500? Is it “internals” (whatever that means) or detail, or length or code, or what? I once heard a great description: A 100-level session makes me say, “wow - I’m smart.” A 500-level session makes me say “wow – that presenter is smart.” And just what is the difference between a 6 and a 7 answer on this question: How well did the speaker know the material? 1  2  3  4  5  6  7  8  9  10 Oh. My. Gosh. How does that make the next session better, or the speaker? And what criteria did you use to answer? And is a “10” better than a “1” (not always clear, and various cultures answer this differently). When it’s all said and done, a speaker basically finds out one thing from the current session evals: “They liked me. They really really liked me.” Or, “Wow. I think I may need to schedule some counseling for the depression I’m about to go into.” You may not think that’s what the speaker hears, but trust me, they do. Those are the only two reactions to the current feedback sheets they get. Either they keep doing what they are doing, or they get their feelings hurt. They just can’t use the information provided to do better. Sorry, but there it is. Keep in mind I do want your feedback. I want to get better. I want you to get your money and time’s worth, probably as much as any speaker alive. But I want those evaluations to be accurate, specific and actionable. I want to know if you had a good time, sure, but I also want to know if I did the right things, and if not, if I can do something different or better. And so, for your consideration, here is the evaluation form I would LOVE for you to use. Feel free to copy it and mail it to me any time. I’m going to put some questions here, and then I’ll even include why they are there. Notice that the form asks you a subjective question right away, and then makes you explain why. That’s work on your part. Notice also that it separates the room and the coffee and the lights and the LiveMeeting from the presenter. So many presenters are faced with circumstances beyond their control, and yet are rated high or low personally on those things. This form helps tease those apart. It’s not numeric. Numbers are easier for the scoring committees but are useless for you and me. So I don’t have any numbers. We’re actually going to have to read these things, not put them in a machine. Hey, if you put in the work to write stuff down, the least we could do is take the time to read it. It’s not anonymous. If you’ve got something to say, say it, and own up to it. People are not “more honest” when they are anonymous, they are less honest. So put your name on it. In fact – this is radical – I posit that these evaluations should be publicly available. Forever. Just like replies to a blog post. Hey, if I’m an organizer, I would LOVE to be able to have access to specific, actionable information on the attendees and the speakers. So if you want mine to be public, go for it. I’ll take the good and the bad. Enjoy. ------------------------------------------------------------------------------------------------------------------------------------------- Session Evaluation – Date, Time, Location, Topic Thanks for giving us your time today. We know that’s valuable, and we hope you learned something you can use from the session. If you can answer these questions as completely as you can, it will help the next person who attends a session here. Your Name: What you do for a living: (We Need your background to evaluate your evaluation) How long you have been doing that: (Again, we need your background to evaluate your evaluation) Paste Session Description Here: (This is what I said I would talk about) Did you like the session?                     No        Meh        Yes (General subjective question – overall “feeling”. You’ll tell us why in a minute.)  Tell us about the venue. Temperature, lights, coffee, or the online sound, performance, anything other than the speaker and the material. (Helps the logistics to be better or as good for the next person) 1. What did you expect to learn in this session? (How did you interpret that extract – did you have expectations that I should work towards for the next person?) 2. Did you learn what you expected to learn? Why? Be very specific. (This is the most important question there is. It tells us how to make the session better for someone like you.) 3. If you were giving this presentation, would you have done anything differently? What? (Helps us to gauge you, the listener, and might give us a great idea on how to do something better. Thanks!) 4. What will you do with the information you got? (Every presenter wants you to learn, and learn something useful. This will help us do that as well or better)

  • StreamInsight Now Available Through Microsoft Update

    - by Roman Schindlauer
    We are pleased to announce that StreamInsight v1.1 is now available for automatic download and install via Microsoft Update globally. In order to enable agile deployment of StreamInsight solutions, you have asked of us a steady cadence of releases with incremental, but highly impactful features and product improvements. Following our StreamInsight 1.0 launch in Spring 2010, we offered StreamInsight 1.1 in Fall 2010 with implicit compatibility and an upgraded setup to support side by side installs. With this setup, your applications will automatically point to the latest runtime, but you still have the choice to point your application back to a 1.0 runtime if you choose to do so. As the next step, in order to enable timely delivery of our releases to you, we are pleased to announce the support for automatic download and install of StreamInsight 1.1 release via Microsoft Update starting this week. If you have a computer: that is subscribed to Microsoft Update (different from Windows Update) has StreamInsight 1.0 installed, and does not yet have StreamInsight 1.1 installed, Microsoft Update will automatically download and install the corresponding StreamInsight 1.1 update side by side with your existing StreamInsight 1.0 installation – across all supported 32-bit and 64-bit Windows operating systems, across 11 supported languages, and across StreamInsight client and server SKUs. This is also supported in WSUS environments, if all your updates are managed from a corporate server (please talk to the WSUS administrator in your enterprise). As an example, if you have SI Client 1.0 DEU and SI Server 1.0 ENU installed on the same computer, Microsoft Update will selectively download and side-by-side install just the SI Client 1.1 DEU and SI Server 1.1 ENU releases. Going forward, Microsoft Update will be our preferred mode of delivery – in addition to support for our download sites, and media based distribution where appropriate. Regards, The StreamInsight Team

  • Deletes that Split Pages and Forwarded Ghosts

    - by Paul White
    Can DELETE operations cause pages to split? Yes. It sounds counter-intuitive on the face of it; deleting rows frees up space on a page, and page splitting occurs when a page needs additional space. Nevertheless, there are circumstances when deleting rows causes them to expand before they can be deleted. The mechanism at work here is row versioning (extract from Books Online below): Isolation Levels The relationship between row-versioning isolation levels (the first bullet point) and page splits is...(read more)

  • Hardware Virtualization no longer required for Windows 7 XP Mode

    - by Jonathan Kehayias
    One of my frustrations in upgrading to Windows 7 last year was that Virtual PC no longer worked since I didn’t have Hardware Virtualization on my CPU.  This really drove my transition entirely to VMware Workstation on my personal laptop.  I recently reinstalled my work laptop (with permission) on Windows 7 Enterprise and figured I’d give XP Mode a look since this machine has Hardware Virtualization enabled.  I was surprised to find that Hardware Virtualization was no longer required,...(read more)

  • TechEd North America 2012-Day 4 #msTechEd #teched

    - by Marco Russo (SQLBI)
    I hadn’t time yesterday to write a blog post before of the beginning of the day and I recover now that I’m already back to Europe. I spent many hours at the Microsoft booth meeting people who asked questions about Tabular, Power View and PowerPivot. I have to say that I’m really glad so many people started using PowerPivot and of the large interest around Tabular. During my BISM: Multidimensional vs. Tabular I’ve been helped by Alberto during the demo (we joked about he was the demo monkey) and the feedback received are good. I tried to compare the strength and weakness of the two modeling options without spending time describing the area in which they are similar. During the days before I had many discussions about scenarios based on snapshots and I added a few slides to the presentation in order to cover this area that I thought was marginal but seems to be a very common one. To know more, watch the presentation when it will be available or wait for some article I’ll write in the future describing these patterns. In less than 10 days, I’ll be at TechEd Europe and I’m really looking forward to meet other Tabular developers and PowerPivot users there!

  • Dreaded SQLs

    - by lavanyadeepak
    Dreaded SQLs We used to think that a SQL statement without a where clause is only dangerous right since running that on a server TSQL is just going to impact the entire table like waving the magic wand. For that reason we should cultivate the habit first to write the statement as select and then to modify the select portion as update. Within the T-SQL Window, I would normally prefer the following first: select * from employee where empid in (4,5) and then once I am satisfied with the results, I would go ahead with the following change: --select * delete from employee where empid in (4,5) Today I just discovered another coding horror. This would typically be applicable in a stored procedure and with respect to variable nomenclature. It is always desirable to have a suitable nomenclature for parameters distinct from the column names and internal variables. This would help quicker debugging of the stored procedures besides enhancing the readability. Else in a quick bout of enthusiasm a statement like   if (@CustomerID = @CustomerID) [when the latter is intended to denote the column name and there is a superflous @ prepended], zeroing in on the problem would be little tricky. Had there been a still powerful nomenclature rules then debugging would have been more straight-forward and simpler right?

    I had an incredibly interesting experience getting to Seattle this week. I flew out of Providence through Philadelphia. Apparently there was some smoke in one of the towers at PHL, so our flight was an hour delayed. I missed my connection by three minutes . I was absolutely amazed that after a one-hour, full ground stop, flights shortly afterward were leaving exactly on time. It was like anti-Aaron magic. I got to the gate and watched my plane back away. My luggage never would have made it but it...(read more)

  • Hyper-V CPU Utilization, Good Tools?

    - by yzorg
    I just learned a ton from this post: Host CPU% doesn't include child VM CPU%, specifically I learned that both the 'host OS' and 'child VM' are siblings within the HyperVisor layer. Are there good utilities for 'watching' the total CPU and other resource counters at the HyperVisor (hardware) layer? I know perfmon (watching special Hyper-V CPU counters) is the standard answer, but I've stayed away from perfmon for ad-hoc monitoring. Is there a good OSS or free tools to 'watch' the resource utilization as I create multiple new VMs running on the server? I'm a developer, so if there aren't any good UI tools to surface this data I'd consider creating one, but only if needed. P.S. My specific scenario is I'm creating new web, SQL and back-end server VMs for new Windows 8 Server and SQL 2012 (entire application stack). I need to monitor them for utilization and know when I need to grow beyond 1 host (I'll need to split the VMs into separate hosts as I hit hardware limits of the 1st host, and diagnose problems).

  • 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)

  • SIMD Extensions for the Database Storage Engine

    - by jchang
    For the last 15 years, Intel and AMD have been progressively adding special purpose extensions to their processor architectures. The extensions mostly pertain to vector operations with Single Instruction, Multiple Data (SIMD) concept. The motivation was that achieving significant performance improvement over each successive generation for the general purpose elements had become extraordinarily difficult. On the other hand, SIMD performance could be significantly improved with special purpose registers...(read more)

  • Cloud Computing - just get started already!

    - by BuckWoody
    OK - you've been hearing about "cloud" (I really dislike that term, but whatever) for over two years. You've equated it with just throwing some VM's in some vendor's datacenter - which is certainly part of it, but not the whole story. There's a whole world of - wait for it - *coding* out there that you should be working on. If you're a developer, this is just a set of servers with operating systems and the runtime layer (like.NET, Java, PHP, etc.) that you can deploy code to and have it run. It can expand in a horizontal way, allowing massive - and I really, honestly mean massive, not just marketing talk kind of scale. We see this every day. If you're not a developer, well, now's the time to learn. Explore a little. Try it. We'll help you. There's a free conference you can attend in November, and you can sign up for it now. It's all on-line, and the tools you need to code are free. Put down Facebook and Twitter for a minute - go sign up. Learn. Do. :) See you there. http://www.windowsazureconf.net/

  • More Denali Execution Plan Warning Goodies

    - by Dave Ballantyne
    In my last blog, I showed how the execution plan in denali has been enhanced by 2 new warnings ,conversion affecting cardinality and conversion affecting seek, which are shown when a data type conversion has happened either implicitly or explicitly. That is not all though, there is more .  Also added are two warnings when performance has been affected due to memory issues. Memory spills to tempdb are a costly operation and happen when SqlServer is under memory pressure and needs to free some up. For a long time you have been able to see these as warnings in a profiler trace as a sort or hash warning event,  but now they are included right in the execution plan.  Not only that but also you can see which operator caused the spill , not just which statement.  Pretty damn handy. Another cause of performance problems relating to memory are memory grant waits.  Here is an informative write up on them,  but simply speaking , SQLServer has to allocate a certain amount of memory for each statement. If it is unable to you get a “memory grant wait”.  Once again there are other methods of analyzing these,  but the plan now shows these too. Don't worry that’s not real production code There is one other new warning that is of interest to me, “Unmatched Indexes”.  Once I find out the conditions under which that fires ill blog about it.

  • Creating a Corporate Data Hub

    - by BuckWoody
    The Windows Azure Marketplace has a rich assortment of data and software offerings for you to use – a type of Software as a Service (SaaS) for IT workers, not necessarily for end-users. Among those offerings is the “Data Hub” – a  codename for a project that ironically actually does what the codename says. In many of our organizations, we have multiple data quality issues. Finding data is one problem, but finding it just once is often a bigger problem. Lots of departments and even individuals have stored the same data more than once, and in some cases, made changes to one of the copies. It’s difficult to know which location or version of the data is authoritative. Then there’s the problem of accessing the data. It’s fairly straightforward to publish a database, share or other location internally to store the data. But then you have to figure out who owns it, how it is controlled, and pass out the various connection strings to those who want to use it. And then you need to figure out how to let folks access the internal data externally – bringing up all kinds of security issues. Finally, in many cases our user community wants us to combine data from the internally sources with external data, bringing up the security, strings, and exploration features up all over again. Enter the Data Hub. This is an online offering, where you assign an administrator and data stewards. You import the data into the service, and it’s available to you - and only you and your organization if you wish. The basic steps for this service are to set up the portal for your company, assign administrators and permissions, and then you assign data areas and import data into them. From there you make them discoverable, and then you have multiple options that you or your users can access that data. You’re then able, if you wish, to combine that data with other data in one location. So how does all that work? What about security? Is it really that easy? And can you really move the data definition off to the Subject Matter Experts (SME’s) that know the particular data stack better than the IT team does? Well, nothing good is easy – but using the Data Hub is actually pretty simple. I’ll give you a link in a moment where you can sign up and try this yourself. Once you sign up, you assign an administrator. From there you’ll create data areas, and then use a simple interface to bring the data in. All of this is done in a portal interface – nothing to install, configure, update or manage. After the data is entered in, and you’ve assigned meta-data to describe it, your users have multiple options to access it. They can simply use the portal – which actually has powerful visualizations you can use on any platform, even mobile phones or tablets.     Your users can also hit the data with Excel – which gives them ultimate flexibility for display, all while using an authoritative, single reference for the data. Since the service is online, they can do this wherever they are – given the proper authentication and permissions. You can also hit the service with simple API calls, like this one from C#: http://msdn.microsoft.com/en-us/library/hh921924  You can make HTTP calls instead of code, and the data can even be exposed as an OData Feed. As you can see, there are a lot of options. You can check out the offering here: http://www.microsoft.com/en-us/sqlazurelabs/labs/data-hub.aspx and you can read the documentation here: http://msdn.microsoft.com/en-us/library/hh921938

  • “Apparently, you signed a software services agreement without fully understanding it.”

    - by Dave Ballantyne
    I am not a lawyer. Let me say that again, I am not a lawyer. Todays Dilbert has prompted me to post about my recent experience with SqlServer licensing. I'm in the technical realm and rarely have much to do with purchasing and licensing.  I say “I need” , budget realities will state weather I actually get.  However, I do keep my ear to the ground and due to my community involvement, I know, or at least have an understanding of, some licensing restrictions. Due to a misunderstanding, Microsoft Licensing stated that we needed licenses for our standby servers.  I knew that that was not the case,  and a quick tweet confirmed this. So after composing an email stating exactly what the machines in question were used for ie Log shipped to and used in a disaster recover scenario only,  and posting several Technet articles to back this up, we saved 2 enterprise edition licences, a not inconsiderable cost. However during this discussion, I was made aware of another ‘legalese’ document that could completely override the referenced articles, and anything I knew, or thought i knew, about SqlServer licensing. Personally, I had no knowledge of this.  The “Purchase Use Rights” agreement would appear to be the volume licensing equivalent of the “End User License Agreement” , click throughs we all know and ignore.  Here is a direct quote from Microsoft licensing, when asked for clarification. “Thanks for your email. Just to give some background on the Product Use Rights (PUR), licenses acquired through volume licensing are bound by the most recent PUR at the time of license acquisition. The link for the current PUR and PUR archive is http://www.microsoft.com/licensing/about-licensing/product-licensing.aspx. Further to this, products acquired through boxed product or pre-installed on hardware (OEM) are bound by the End User License Agreement (EULA). The PUR will explain limitations, license requirements and rulings on areas like multiplexing, virtualization, processor licensing, etc. When an article will appear on a Microsoft site or blog describing the licensing of a product, it will be using the PUR as a base. Due to the writing style or language used by the person writing areas of the website or technical blogs, the PUR is what you should use as a rule and not any of the other media. The PUR is updated quarterly and will reference every product available at that time working on the latest version unless otherwise stated. The crux of this is that the PUR is written after extensive discussions between the different branches of Microsoft (legal, technical, etc) and the wording is then approved. This is not always the case for some pages explaining licensing as they are merely intended to advise and not subject to the intense scrutiny as the PUR.” So, exactly what does that mean ? My take :  This is a living document, “updated quarterly” , though presumably this could be done on a whim and a fancy.  It could state , you are only licensed if ,that during install you stand in a corner juggling and that photographic evidence is required. A plainly ridiculous demand but,  what else could it override or new requirements could it state that change your existing understanding of the product or your legal usage of it. As i say, im not a lawyer, but are you checking the PURA prior to purchase ?
