• BAM design pointers

  - by Kavitha Srinivasan

  In working recently with a large Oracle customer on SOA and BAM, I discovered that some BAM best practices are not quite well known as I had always assumed ! There is a doc bug out to formally incorporate those learnings but here are a few notes..  EMS-DO parity When using EMS (Enterprise Message Source) as a BAM feed, the best practice is to use one EMS to write to one Data Object. There is a possibility of collisions and duplicates when multiple EMS write to the same row of a DO at the same time. This customer had 17 EMS writing to one DO at the same time. Every sensor in their BPEL process writes to one topic but the Topic was read by 1 EMS corresponding to one sensor. They then used XSL within BAM to transform the payload into the BAM DO format. And hence for a given BPEL instance, 17 sensors fired, populated 1 JMS topic, was consumed by 17 EMS which in turn wrote to 1 DataObject.(You can image what would happen for later versions of the application that needs to send more information to BAM !).  We modified their design to use one Master XSL based on sensorname for all sensors relating to a DO- say Data Object 'Orders' and were able to thus reduce the 17 EMS to 1 with a master XSL. For those of you wondering about how squeaky clean this design is, you are right ! This is indeed not squeaky clean and that brings us to yet another 'inferred' best practice. (I try very hard not to state the obvious in my blogs with the hope that everytime I blog, it is very useful but this one is an exception.) Transformations and Calculations It is optimal to do transformations within an engine like BPEL. Not only does this provide modelling ease with a nice GUI XSL mapper in JDeveloper, the XSL engine in BPEL is quite efficient at runtime as well. And so, doing XSL transformations in BAM is not quite prudent.  The same is true for any non-trivial calculations as well. It is best to do all transformations,calcuations and sanitize the data in a BPEL or like layer and then send this to BAM (via JMS, WS etc.) This then delegates simply the function of report rendering and mechanics of real-time reporting to the Oracle BAM reporting tool which it is most suited to do. All nulls are not created equal Here is yet another possibly known fact but reiterated here. For an EMS with an Upsert operation: a) If Empty tags or tags with no value are sent like <Tag1/> or <Tag1></Tag1>, the DO will be overwritten with --null-- b) If Empty tags are suppressed ie not generated at all, the corresponding DO field will NOT be overwritten. The field will have whatever value existed previously.  For an EMS with an Insert operation, both tags with an empty value and no tags result in –null-- being written to the DO. Hope this helps .. Happy 4th!

• What micro web-framework has the lowest overhead but includes templating

  - by Simon Martin

  I want to rewrite a simple small (10 page) website and besides a contact form it could be written in pure html. It is currently built with classic asp and Dreamweaver templates. The reason I'm not simply writing 10 html pages is that I want to keep the layout all in 1 place so would need either includes or a masterpage. I don't want to use Dreamweaver templates, or batch processing (like org-mode) because I want to be able to edit using notepad (or Visual Studio) because occasionally I might need to edit a file on the server (Go Daddy's IIS admin interface will let me edit text). I don't want to use ASP.NET MVC or WebForms (which I use in my day job) because I don't need all the overhead they bring with them when essentially I'm serving up 9 static files, 1 contact form and 1 list of clubs (that I aim to use jQuery to filter). The shared hosting package I have on Go Daddy seems to take a long time to spin up when serving aspx files. Currently the clubs page is driven from an MS SQL database that I try to keep up to date by manually checking the dojo locator on the main HQ pages and editing the entries myself, this is again way over the top. I aim to get a text file with the club details (probably in JSON or xml format) and use that as the source for the clubs page. There will need to be a bit of programming for this as the HQ site is unable to provide an extract / feed so something will have to scrape the site periodically to update my clubs persistence file. I'd like that to be automated - but I'm happy to have that triggered on a visit to the clubs page so I don't need to worry about scheduling a job. I would probably have a separate process that updates the persistence that has nothing to do with the rest of the site. Ideally I'd like to use Mercurial (or git) to publish, I know Bitbucket (and github) both serve static page sites so they wouldn't work in this scenario (dynamic pages and a contact form) but that's the model I'd like to use if there is such a thing. My requirements are: Simple templating system, 1 place to define header, footers, menu etc., that can be edited using just notepad. Very minimal / lightweight framework. I don't need a monster for 10 pages Must run either on IIS7 (shared Go Daddy Windows hosting) or other free host

• Miracle Growth Of Organs From Our Own Cells

  - by Rekha

  At the current situation, there is a shortage of healthy organs. The donor and patient also have to be closely matched and there are chances for the patient’s immune system may reject the transplant. Right now, researchers are seriously involved in a new kind of solution: "bioartifical" organs are being grown from the patient’s own cells. There are a few people who have already received lab-grown bladders. Bladder technique was developed by Anthony Atala of the Wake Forest Institute for Regenerative Medicine in Winston-Salem, North Carolina. The healthy cells from the patient’s diseased bladder is taken and cause them to multiply profusely in petri dishes. The muscle cells go on the outside, urothelial cells on the inside by layering the cells one layer at a time. The bladder-to-be is then incubated at body temperature until the cells form functioning tissue. This process could take six to eight months. Organs with lots of blood vessels, such as kidneys or livers, are harder to grow than hollow ones like bladders. Atala’s group works on 22 organs and tissues including ears, recently made a functioning piece of human liver. Others in the list includes:  Columbia University – Jawbone, Yale University – Lung, University of Minnesota – Rat heart, University of Michigan – Artificial Kidney There are possibilities that growing a copy of patient’s organ is not always possible – for instance, when the original is completely damaged by cancer. By using stem cell bank collected without harming human embryos from amniotic fluid in the womb, those cells are coaxed into becoming heart, liver and other organ cells. A bank of 1,00,000 stem cell samples would have enough genetic variety to match nearly any patient. Surgeons can order organs grown as needed instead of waiting for the perfect donor. "There are few things as devastating for a surgeon as knowing you have to replace the tissue and you’re doing something that’s not ideal," says Atala, a urologic surgeon himself. "Wouldn’t it be great if they had their own organ?" Great for the patient especially, he means.

• Introduction to Lean Software Development and Kanban Systems

  - by Ben Griswold

  Last year I took myself through a crash course on Lean Software Development and Kanban Systems in preparation for an in-house presentation.  I learned a bunch.  In this series, I’ll be sharing what I learned with you.   If your career looks anything like mine, you have probably been affiliated with a company or two which pushed requirements gathering and documentation to the nth degree. To add insult to injury, they probably added planning process (documentation, requirements, policies, meetings, committees) to the extent that it possibly retarded any progress. In my opinion, the typical company resembles the quote from Tom DeMarco. It isn’t enough just to do things right – we also had to say in advance exactly what we intended to do and then do exactly that. In the 1980s, Toyota turned the tables and revolutionize the automobile industry with their approach of “Lean Manufacturing.” A massive paradigm shift hit factories throughout the US and Europe. Mass production and scientific management techniques from the early 1900’s were questioned as Japanese manufacturing companies demonstrated that ‘Just-in-Time’ was a better paradigm. The widely adopted Japanese manufacturing concepts came to be known as ‘lean production’. Lean Thinking capitalizes on the intelligence of frontline workers, believing that they are the ones who should determine and continually improve the way they do their jobs. Lean puts main focus on people and communication – if people who produce the software are respected and they communicate efficiently, it is more likely that they will deliver good product and the final customer will be satisfied. In time, the abstractions behind lean production spread to logistics, and from there to the military, to construction, and to the service industry. As it turns out, principles of lean thinking are universal and have been applied successfully across many disciplines. Lean has been adopted by companies including Dell, FedEx, Lens Crafters, LLBean, SW Airlines, Digital River and eBay. Lean thinking got its name from a 1990’s best seller called The Machine That Changed the World : The Story of Lean Production. This book chronicles the movement of automobile manufacturing from craft production to mass production to lean production. Tom and Mary Poppendieck, that is.  Here’s one of their books: Implementing Lean Software Thinking: From Concept to Cash Our in-house presentations are supposed to run no more than 45 minutes.  I really cranked and got through my 87 slides in just under an hour. Of course, I had to cheat a little – I only covered the 7 principles and a single practice. In the next part of the series, we’ll dive into Principle #1: Eliminate Waste. And I am going to be a little obnoxious about listing my Lean and Kanban references with every series post.  The references are great and they deserve this sort of attention.

• ANTS Memory Profiler 7.0 Review

  - by Michael B. McLaughlin

  (This is my first review as a part of the GeeksWithBlogs.net Influencers program. It’s a program in which I (and the others who have been selected for it) get the opportunity to check out new products and services and write reviews about them. We don’t get paid for this, but we do generally get to keep a copy of the software or retain an account for some period of time on the service that we review. In this case I received a copy of Red Gate Software’s ANTS Memory Profiler 7.0, which was released in January. I don’t have any upgrade rights nor is my review guided, restrained, influenced, or otherwise controlled by Red Gate or anyone else. But I do get to keep the software license. I will always be clear about what I received whenever I do a review – I leave it up to you to decide whether you believe I can be objective. I believe I can be. If I used something and really didn’t like it, keeping a copy of it wouldn’t be worth anything to me. In that case though, I would simply uninstall/deactivate/whatever the software or service and tell the company what I didn’t like about it so they could (hopefully) make it better in the future. I don’t think it’d be polite to write up a terrible review, nor do I think it would be a particularly good use of my time. There are people who get paid for a living to review things, so I leave it to them to tell you what they think is bad and why. I’ll only spend my time telling you about things I think are good.) Overview of Common .NET Memory Problems When coming to land of managed memory from the wilds of unmanaged code, it’s easy to say to one’s self, “Wow! Now I never have to worry about memory problems again!” But this simply isn’t true. Managed code environments, such as .NET, make many, many things easier. You will never have to worry about memory corruption due to a bad pointer, for example (unless you’re working with unsafe code, of course). But managed code has its own set of memory concerns. For example, failing to unsubscribe from events when you are done with them leaves the publisher of an event with a reference to the subscriber. If you eliminate all your own references to the subscriber, then that memory is effectively lost since the GC won’t delete it because of the publishing object’s reference. When the publishing object itself becomes subject to garbage collection then you’ll get that memory back finally, but that could take a very long time depending of the life of the publisher. Another common source of resource leaks is failing to properly release unmanaged resources. When writing a class that contains members that hold unmanaged resources (e.g. any of the Stream-derived classes, IsolatedStorageFile, most classes ending in “Reader” or “Writer”), you should always implement IDisposable, making sure to use a properly written Dispose method. And when you are using an instance of a class that implements IDisposable, you should always make sure to use a 'using' statement in order to ensure that the object’s unmanaged resources are disposed of properly. (A ‘using’ statement is a nicer, cleaner looking, and easier to use version of a try-finally block. The compiler actually translates it as though it were a try-finally block. Note that Code Analysis warning 2202 (CA2202) will often be triggered by nested using blocks. A properly written dispose method ensures that it only runs once such that calling dispose multiple times should not be a problem. Nonetheless, CA2202 exists and if you want to avoid triggering it then you should write your code such that only the innermost IDisposable object uses a ‘using’ statement, with any outer code making use of appropriate try-finally blocks instead). Then, of course, there are situations where you are operating in a memory-constrained environment or else you want to limit or even eliminate allocations within a certain part of your program (e.g. within the main game loop of an XNA game) in order to avoid having the GC run. On the Xbox 360 and Windows Phone 7, for example, for every 1 MB of heap allocations you make, the GC runs; the added time of a GC collection can cause a game to drop frames or run slowly thereby making it look bad. Eliminating allocations (or else minimizing them and calling an explicit Collect at an appropriate time) is a common way of avoiding this (the other way is to simplify your heap so that the GC’s latency is low enough not to cause performance issues). ANTS Memory Profiler 7.0 When the opportunity to review Red Gate’s recently released ANTS Memory Profiler 7.0 arose, I jumped at it. In order to review it, I was given a free copy (which does not include upgrade rights for future versions) which I am allowed to keep. For those of you who are familiar with ANTS Memory Profiler, you can find a list of new features and enhancements here. If you are an experienced .NET developer who is familiar with .NET memory management issues, ANTS Memory Profiler is great. More importantly still, if you are new to .NET development or you have no experience or limited experience with memory profiling, ANTS Memory Profiler is awesome. From the very beginning, it guides you through the process of memory profiling. If you’re experienced and just want dive in however, it doesn’t get in your way. The help items GAHSFLASHDAJLDJA are well designed and located right next to the UI controls so that they are easy to find without being intrusive. When you first launch it, it presents you with a “Getting Started” screen that contains links to “Memory profiling video tutorials”, “Strategies for memory profiling”, and the “ANTS Memory Profiler forum”. I’m normally the kind of person who looks at a screen like that only to find the “Don’t show this again” checkbox. Since I was doing a review, though, I decided I should examine them. I was pleasantly surprised. The overview video clocks in at three minutes and fifty seconds. It begins by showing you how to get started profiling an application. It explains that profiling is done by taking memory snapshots periodically while your program is running and then comparing them. ANTS Memory Profiler (I’m just going to call it “ANTS MP” from here) analyzes these snapshots in the background while your application is running. It briefly mentions a new feature in Version 7, a new API that give you the ability to trigger snapshots from within your application’s source code (more about this below). You can also, and this is the more common way you would do it, take a memory snapshot at any time from within the ANTS MP window by clicking the “Take Memory Snapshot” button in the upper right corner. The overview video goes on to demonstrate a basic profiling session on an application that pulls information from a database and displays it. It shows how to switch which snapshots you are comparing, explains the different sections of the Summary view and what they are showing, and proceeds to show you how to investigate memory problems using the “Instance Categorizer” to track the path from an object (or set of objects) to the GC’s root in order to find what things along the path are holding a reference to it/them. For a set of objects, you can then click on it and get the “Instance List” view. This displays all of the individual objects (including their individual sizes, values, etc.) of that type which share the same path to the GC root. You can then click on one of the objects to generate an “Instance Retention Graph” view. This lets you track directly up to see the reference chain for that individual object. In the overview video, it turned out that there was an event handler which was holding on to a reference, thereby keeping a large number of strings that should have been freed in memory. Lastly the video shows the “Class List” view, which lets you dig in deeply to find problems that might not have been clear when following the previous workflow. Once you have at least one memory snapshot you can begin analyzing. The main interface is in the “Analysis” tab. You can also switch to the “Session Overview” tab, which gives you several bar charts highlighting basic memory data about the snapshots you’ve taken. If you hover over the individual bars (and the individual colors in bars that have more than one), you will see a detailed text description of what the bar is representing visually. The Session Overview is good for a quick summary of memory usage and information about the different heaps. You are going to spend most of your time in the Analysis tab, but it’s good to remember that the Session Overview is there to give you some quick feedback on basic memory usage stats. As described above in the summary of the overview video, there is a certain natural workflow to the Analysis tab. You’ll spin up your application and take some snapshots at various times such as before and after clicking a button to open a window or before and after closing a window. Taking these snapshots lets you examine what is happening with memory. You would normally expect that a lot of memory would be freed up when closing a window or exiting a document. By taking snapshots before and after performing an action like that you can see whether or not the memory is really being freed. If you already know an area that’s giving you trouble, you can run your application just like normal until just before getting to that part and then you can take a few strategic snapshots that should help you pin down the problem. Something the overview didn’t go into is how to use the “Filters” section at the bottom of ANTS MP together with the Class List view in order to narrow things down. The video tutorials page has a nice 3 minute intro video called “How to use the filters”. It’s a nice introduction and covers some of the basics. I’m going to cover a bit more because I think they’re a really neat, really helpful feature. Large programs can bring up thousands of classes. Even simple programs can instantiate far more classes than you might realize. In a basic .NET 4 WPF application for example (and when I say basic, I mean just MainWindow.xaml with a button added to it), the unfiltered Class List view will have in excess of 1000 classes (my simple test app had anywhere from 1066 to 1148 classes depending on which snapshot I was using as the “Current” snapshot). This is amazing in some ways as it shows you how in stark detail just how immensely powerful the WPF framework is. But hunting through 1100 classes isn’t productive, no matter how cool it is that there are that many classes instantiated and doing all sorts of awesome things. Let’s say you wanted to examine just the classes your application contains source code for (in my simple example, that would be the MainWindow and App). Under “Basic Filters”, click on “Classes with source” under “Show only…”. Voilà. Down from 1070 classes in the snapshot I was using as “Current” to 2 classes. If you then click on a class’s name, it will show you (to the right of the class name) two little icon buttons. Hover over them and you will see that you can click one to view the Instance Categorizer for the class and another to view the Instance List for the class. You can also show classes based on which heap they live on. If you chose both a Baseline snapshot and a Current snapshot then you can use the “Comparing snapshots” filters to show only: “New objects”; “Surviving objects”; “Survivors in growing classes”; or “Zombie objects” (if you aren’t sure what one of these means, you can click the helpful “?” in a green circle icon to bring up a popup that explains them and provides context). Remember that your selection(s) under the “Show only…” heading will still apply, so you should update those selections to make sure you are seeing the view you want. There are also links under the “What is my memory problem?” heading that can help you diagnose the problems you are seeing including one for “I don’t know which kind I have” for situations where you know generally that your application has some problems but aren’t sure what the behavior you have been seeing (OutOfMemoryExceptions, continually growing memory usage, larger memory use than expected at certain points in the program). The Basic Filters are not the only filters there are. “Filter by Object Type” gives you the ability to filter by: “Objects that are disposable”; “Objects that are/are not disposed”; “Objects that are/are not GC roots” (GC roots are things like static variables); and “Objects that implement _______”. “Objects that implement” is particularly neat. Once you check the box, you can then add one or more classes and interfaces that an object must implement in order to survive the filtering. Lastly there is “Filter by Reference”, which gives you the option to pare down the list based on whether an object is “Kept in memory exclusively by” a particular item, a class/interface, or a namespace; whether an object is “Referenced by” one or more of those choices; and whether an object is “Never referenced by” one or more of those choices. Remember that filtering is cumulative, so anything you had set in one of the filter sections still remains in effect unless and until you go back and change it. There’s quite a bit more to ANTS MP – it’s a very full featured product – but I think I touched on all of the most significant pieces. You can use it to debug: a .NET executable; an ASP.NET web application (running on IIS); an ASP.NET web application (running on Visual Studio’s built-in web development server); a Silverlight 4 browser application; a Windows service; a COM+ server; and even something called an XBAP (local XAML browser application). You can also attach to a .NET 4 process to profile an application that’s already running. The startup screen also has a large number of “Charting Options” that let you adjust which statistics ANTS MP should collect. The default selection is a good, minimal set. It’s worth your time to browse through the charting options to examine other statistics that may also help you diagnose a particular problem. The more statistics ANTS MP collects, the longer it will take to collect statistics. So just turning everything on is probably a bad idea. But the option to selectively add in additional performance counters from the extensive list could be a very helpful thing for your memory profiling as it lets you see additional data that might provide clues about a particular problem that has been bothering you. ANTS MP integrates very nicely with all versions of Visual Studio that support plugins (i.e. all of the non-Express versions). Just note that if you choose “Profile Memory” from the “ANTS” menu that it will launch profiling for whichever project you have set as the Startup project. One quick tip from my experience so far using ANTS MP: if you want to properly understand your memory usage in an application you’ve written, first create an “empty” version of the type of project you are going to profile (a WPF application, an XNA game, etc.) and do a quick profiling session on that so that you know the baseline memory usage of the framework itself. By “empty” I mean just create a new project of that type in Visual Studio then compile it and run it with profiling – don’t do anything special or add in anything (except perhaps for any external libraries you’re planning to use). The first thing I tried ANTS MP out on was a demo XNA project of an editor that I’ve been working on for quite some time that involves a custom extension to XNA’s content pipeline. The first time I ran it and saw the unmanaged memory usage I was convinced I had some horrible bug that was creating extra copies of texture data (the demo project didn’t have a lot of texture data so when I saw a lot of unmanaged memory I instantly figured I was doing something wrong). Then I thought to run an empty project through and when I saw that the amount of unmanaged memory was virtually identical, it dawned on me that the CLR itself sits in unmanaged memory and that (thankfully) there was nothing wrong with my code! Quite a relief. Earlier, when discussing the overview video, I mentioned the API that lets you take snapshots from within your application. I gave it a quick trial and it’s very easy to integrate and make use of and is a really nice addition (especially for projects where you want to know what, if any, allocations there are in a specific, complicated section of code). The only concern I had was that if I hadn’t watched the overview video I might never have known it existed. Even then it took me five minutes of hunting around Red Gate’s website before I found the “Taking snapshots from your code" article that explains what DLL you need to add as a reference and what method of what class you should call in order to take an automatic snapshot (including the helpful warning to wrap it in a try-catch block since, under certain circumstances, it can raise an exception, such as trying to call it more than 5 times in 30 seconds. The difficulty in discovering and then finding information about the automatic snapshots API was one thing I thought could use improvement. Another thing I think would make it even better would be local copies of the webpages it links to. Although I’m generally always connected to the internet, I imagine there are more than a few developers who aren’t or who are behind very restrictive firewalls. For them (and for me, too, if my internet connection happens to be down), it would be nice to have those documents installed locally or to have the option to download an additional “documentation” package that would add local copies. Another thing that I wish could be easier to manage is the Filters area. Finding and setting individual filters is very easy as is understanding what those filter do. And breaking it up into three sections (basic, by object, and by reference) makes sense. But I could easily see myself running a long profiling session and forgetting that I had set some filter a long while earlier in a different filter section and then spending quite a bit of time trying to figure out why some problem that was clearly visible in the data wasn’t showing up in, e.g. the instance list before remembering to check all the filters for that one setting that was only culling a few things from view. Some sort of indicator icon next to the filter section names that appears you have at least one filter set in that area would be a nice visual clue to remind me that “oh yeah, I told it to only show objects on the Gen 2 heap! That’s why I’m not seeing those instances of the SuperMagic class!” Something that would be nice (but that Red Gate cannot really do anything about) would be if this could be used in Windows Phone 7 development. If Microsoft and Red Gate could work together to make this happen (even if just on the WP7 emulator), that would be amazing. Especially given the memory constraints that apps and games running on mobile devices need to work within, a good memory profiler would be a phenomenally helpful tool. If anyone at Microsoft reads this, it’d be really great if you could make something like that happen. Perhaps even a (subsidized) custom version just for WP7 development. (For XNA games, of course, you can create a Windows version of the game and use ANTS MP on the Windows version in order to get a better picture of your memory situation. For Silverlight on WP7, though, there’s quite a bit of educated guess work and WeakReference creation followed by forced collections in order to find the source of a memory problem.) The only other thing I found myself wanting was a “Back” button. Between my Windows Phone 7, Zune, and other things, I’ve grown very used to having a “back stack” that lets me just navigate back to where I came from. The ANTS MP interface is surprisingly easy to use given how much it lets you do, and once you start using it for any amount of time, you learn all of the different areas such that you know where to go. And it does remember the state of the areas you were previously in, of course. So if you go to, e.g., the Instance Retention Graph from the Class List and then return back to the Class List, it will remember which class you had selected and all that other state information. Still, a “Back” button would be a welcome addition to a future release. Bottom Line ANTS Memory Profiler is not an inexpensive tool. But my time is valuable. I can easily see ANTS MP saving me enough time tracking down memory problems to justify it on a cost basis. More importantly to me, knowing what is happening memory-wise in my programs and having the confidence that my code doesn’t have any hidden time bombs in it that will cause it to OOM if I leave it running for longer than I do when I spin it up real quickly for debugging or just to see how a new feature looks and feels is a good feeling. It’s a feeling that I like having and want to continue to have. I got the current version for free in order to review it. Having done so, I’ve now added it to my must-have tools and will gladly lay out the money for the next version when it comes out. It has a 14 day free trial, so if you aren’t sure if it’s right for you or if you think it seems interesting but aren’t really sure if it’s worth shelling out the money for it, give it a try.

• ASP.Net MVC - how to post values to the server that are not in an input element

  - by David Carter

  Problem As was mentioned in a previous blog I am building a web page that allows the user to select dates in a calendar and then shows the dates in an unordered list. The problem now is that those dates need to be sent to the server on page submit so that they can be saved to the database. If I was storing the dates in an input element, say a textbox, that wouldn't be an issue but because they are in an html element whose contents are not posted to the server an alternative strategy needs to be developed. Solution The approach that I took to solve this problem is as follows: 1. Place a hidden input field on the form <input id="hiddenDates" name="hiddenDates" type="hidden" value="" /> ASP.Net MVC has an Html helper with a method called Hidden() that will do this for you @Html.Hidden("hiddenDates"). 2. Copy the values from the html element to the hidden input field before submitting the form The following javascript is added to the page:        $(function () {          $('#formCreate').submit(function () {               PopulateHiddenDates();          });        });            function PopulateHiddenDates() {          var dateValues = '';          $($('#dateList').children('li')).each(function(index) {             dateValues += $(this).attr("id") + ",";          });          $('#hiddenDates').val(dateValues);        } I'm using jQuery to bind to the form submit event so that my method to populate the hidden field gets called before the form is submitted. The dateList element is an unordered list and by using the jQuery each function I can itterate through all the <li> items that it contains, get each items id attribute (to which I have assigned the value of the date in millisecs) and write them to the hidden field as a comma delimited string. 3. Process the dates on the server        [HttpPost]         public ActionResult Create(string hiddenDates, string utcOffset)         {            List<DateTime> dates = GetDates(hiddenDates, utcOffset);         }         private List<DateTime> GetDates(string hiddenDates, int utcOffset)         {             List<DateTime> dates = new List<DateTime>();             var values = hiddenDates.Split(",".ToCharArray(),StringSplitOptions.RemoveEmptyEntries);             foreach (var item in values)             {                 DateTime newDate = new DateTime(1970, 1, 1).AddMilliseconds(double.Parse(item)).AddMinutes(utcOffset*-1);                 dates.Add(newDate);                }             return dates;         } By declaring a parameter with the same name as the hidden field ASP.Net will take care of finding the corresponding entry in the form collection posted back to the server and binding it to the hiddenDates parameter! Excellent! I now have my dates the user selected and I can save them to the database. I have also used the same technique to pass back a utcOffset so that I know what timezone the user is in and I can show the dates correctly to users in other timezones if necessary (this isn't strictly necessary at the moment but I plan to introduce times later), Saving multiple dates from an unordered list - DONE!

• IT Admin for Thrill Seekers

  - by Tony Davis

  A developer suggested to me recently that the life of the DBA was, surely, a dull one. My first reaction was indignation, but quickly followed by the thought that for many people excitement isn't necessarily the most desirable aspect of their job. It's true that some aspects of the DBA role seem guaranteed to quieten the pulse; in the days of tape backups, time must have slowed to eternity for the person whose job it was to oversee this process, placing tapes into secure containers, ensuring correct labeling, and.sorry, I drifted off there for a second. On the other hand, if you follow the adventures of the likes of Brent Ozar or Tom LaRock, you'd be forgiven for thinking that much of a database guy's time is spent, metaphorically, diving through plate glass windows in tight fitting underwear in order to extract grateful occupants from burning database applications. Alas it isn't true of the majority, but it isn't as dull as some people imagine, and is a helter-skelter ride compared with some other IT roles. Every IT department has people who toil away in shadowy corners doing quiet but mysterious tasks. When you ask them to explain what they do, you almost immediately want them to stop, but you hear enough to appreciate that these tasks are often absolutely vital to the smooth functioning of an IT organization. Compared with them, the DBAs are prima donnas. Here are a few nominations: Installation engineer - install all of the company's laptops and workstations, and software, deal with licensing, shipping and data entry.many organizations, especially those subject to tight regulation, would simply grind to a halt without their efforts. Localization engineer - Not quite software engineering, not quite translation, the job is to rebuild a product in a different language and make sure everything still works. QA Tester - firstly, I should say that the testers at Red Gate seem to me some of the most-fulfilled in the company. I refer here to the QA Tester whose job is more-or-less entirely to read a script, click some buttons and make sure the actual and expected values match. Configuration manager - for example, someone whose main job is to configure build environments so that devs can access their source code; assuredly necessary for the smooth functioning and productivity of the team, and hopefully well-paid. So what other sort of job in IT should one choose if the work of a DBA proves to be too exciting? Or are these roles secretly more exciting than many imagine? I invite you all to put forward your own suggestions. Cheers, Tony.

• Manage Your Favorite Social Accounts in Chrome and Iron with Seesmic

  - by Asian Angel

  Are you looking for a way to manage your Twitter, Facebook, Google Buzz, LinkedIn, and Foursquare accounts all in one place? Using the Seesmic Web App for Chrome and Iron you can access your favorite accounts and manage them in a single, simple-to-use interface. A feature that we loved from the start was the ability to access Twitter without creating a special Seesmic account. And in these days of multiple accounts who needs another one to complicate things up? All that you need to do is to sign in with your user name/e-mail along with your password. You do have to authorize access for Seesmic to connect with your account but the whole process (login & authorization) is handled in a single window instance. Now on to a quick look at some of the UI features… The sidebar allows you to add additional columns to the main interface, set your favorite location for Trends, and tie in additional social services as desired. You can also access additional options and controls in the upper right corner. When you are ready to start tweeting click in the blank at the top and enter your text, etc. in the convenient drop-down window that appears. Another nice perk is the ability to switch to a black and grey theme if the white is too bright for your needs. The Seesmic web app provides a simple-to-use, highly efficient way to manage your Twitter account and other favorite social services in a single tab interface.

• Executable Resumes

  - by Liam McLennan

  Over the past twelve months I have been thinking a lot about executable specifications. Long considered the holy grail of agile software development, executable specifications means expressing a program’s functionality in a way that is both readable by the customer and computer verifiable in an automatic, repeatable way. With the current generation of BDD and ATDD tools executable specifications seem finally within the reach of a significant percentage of the development community. Lately, and partly as a result of my craftsmanship tour, I have decided that soon I am going to have to get a job (gasp!). As Dave Hoover describes in Apprenticeship Patters, “you … have mentors and kindred spirits that you meet with periodically, [but] when it comes to developing software, you work alone.” The time may have come where the only way for me to feel satisfied and enriched by my work is to seek out a work environment where I can work with people smarter and more knowledgeable than myself. Having been on both sides of the interview desk many times I know how difficult and unreliable the process can be. Therefore, I am proposing the idea of executable resumes. As a journeyman programmer looking for a fruitful work environment I plan to write an application that demonstrates my understanding of the state of the art. Potential employers can download, view and execute my executable resume and judge wether my aesthetic sensibility matches their own. The concept of the executable resume is based upon the following assertion: A line of code answers a thousand interview questions Asking people about their experiences and skills is not a direct way of assessing their value to your organisation. Often it simple assesses their ability to mislead an interviewer. An executable resume demonstrates: The highest quality code that the person is able to produce. That the person is sufficiently motivated to produce something of value in their own time. That the person loves their craft. The idea of publishing a program to demonstrate a developer’s skills comes from Rob Conery, who suggested that each developer should build their own blog engine since it is the public representation of their level of mastery. Rob said: Luke had to build his own lightsaber – geeks should have to build their own blogs. And that should be their resume. In honour of Rob’s inspiration I plan to build a blog engine as my executable resume. While it is true that the world does not need another blog engine it is as good a project as any, it is a well understood domain, and I have not found an existing blog engine that I like. Executable resumes fit well with the software craftsmanship metaphor. It is not difficult to imagine that under the guild system master craftsmen may have accepted journeymen based on the quality of the work they had produced in the past. We now understand that when it comes to the functionality of an application that code is the final arbiter. Why not apply the same rule to hiring?

• Idea to develop a caching server between IIS and SQL Server

  - by John

  I work on a few high traffic websites that all share the same database and that are all heavily database driven. Our SQL server is max-ed out and, although we have already implemented many changes that have helped but the server is still working too hard. We employ some caching in our website but the type of queries we use negate using SQL dependency caching. We tried SQL replication to try and kind of load balance but that didn't prove very successful because the replication process is quite demanding on the servers too and it needed to be done frequently as it is important that data is up to date. We do use a Varnish web caching server (Linux based) to take a bit of the load off both the web and database server but as a lot of the sites are customised based on the user we can only do so much. Anyway, the reason for this question... Varnish gave me an idea for a possible application that might help in this situation. Just like Varnish sits between a web browser and the web server and caches response from the web server, I was wondering about the possibility of creating something that sits between the web server and the database server. Imagine that all SQL queries go through this SQL caching server. If it's a first time query then it will get recorded, and the result requested from the SQL server and stored locally on the cache server. If it's a repeat request within a set time then the result gets retrieved from the local copy without the query being sent to the SQL server. The caching server could also take advantage of SQL dependency caching notifications. This seems like a good idea in theory. There's still the same amount of data moving back and forward from the web server, but the SQL server is relieved of the work of processing the repeat queries. I wonder about how difficult it would be to build a service that sort of emulates requests and responses from SQL server, whether SQL server's own caching is doing enough of this already that this wouldn't be a benefit, or even if someone has done this before and I haven't found it? I would welcome any feedback or any references to any relevant projects.

• Windows 8: Everything from design, build, and how to sell a Metro style app

  - by Thomas Mason

  For me, there are a lot of similarities between an application developed for Windows Phone and a Metro style app developed for Windows 8. A Windows Phone 7 application (rather than an XNA game) is built in .NET and XAML against a subset of the .NET framework and the application has a lifecycle which needs to be conscious of battery life and so is split out into foreground/background pieces. The application is sandboxed in terms of its interactions with the local device and is packaged with a manifest which describes those interactions. The app needs to be aware of network connectivity status and its work on the network is done asynchronously to preserve the user experience.The app is packaged and deployed to a Marketplace which the user browses to find the app, read reviews, perhaps purchase it and then install it and receive updates over time. Quite a lot of those statements are as true of a Windows 8 Metro style app as they are for a Windows Phone app and so a Windows Phone app developer already has a good head start when it comes to building Metro style apps for Windows 8. With that in mind, there is an event to help developers with a Windows Phone app in Marketplace to begin the process of looking at Windows 8 and whether you can get a quick win by bringing your Phone application onto Windows. The idea of the event was to provide a space where developers can get together over 2 days and take the time out to look at what it means to take their app from Windows Phone to Windows 8. Kicking off on Saturday 16th June at 10am, we are told they have plenty of power sockets, WiFi, whiteboards, drinks, pizza, games, prizes and some quiet space that you can work in. Including people on hand with Windows Phone and Windows 8 experience to help everything along the way. There will be an attendee-voted schedule of talks but we’ll keep these out of your way if you just want to get on and code. We’ll also provide information around submitting your app to the Windows Store If you have a Windows Phone app in Marketplace, now’s a great time to look at getting it onto Windows 8. Sign up. Bring your laptop. Bring your app. Bring Windows 8 and Visual Studio 11. And everyone will their best to help you get your app onto Windows 8. Location & Venue TBA but it will be in central London, accessible by major railway and underground transportation. Day 1 Saturday 16th June 10am – 9pm Day 2 Sunday 17th June 10am – 4pm

• Wireless Drivers for Broadcom BCM 4321 (14e4:4329) will not stay connected to a wireless network

  - by Eugene

  So, I'm not necessary new to Linux, I just never took the time to learn it, so please, bare with me. I just swapped out one of my wireless cards from one computer to another. This wireless card in question would be a "Broadcom BCM4321 (14e4:4329)" or actually a "Netgear WN311B Rangemax Next 270 Mbps Wireless PCI Adapter", but that's not important. I've tried (but probably screwed up in the process) installing the "wl" , "b43" and "brcmsmac" drivers, or at least I think I did. Currently I have only the following drivers loaded: eugene@EugeneS-PCu:~$ lsmod | grep "brcmsmac\|b43\|ssb\|bcma\|wl" b43 387371 0 bcma 52096 1 b43 mac80211 630653 1 b43 cfg80211 484040 2 b43,mac80211 ssb_hcd 12869 0 ssb 62379 2 b43,ssb_hcd The main issue is that with most of the drivers available that I've installed, they will find my wireless network but, they will only stay connected for about a minute with abnormally slow speed and then all of a sudden disconnect. Currently, the computer is hooked into another to share it's connect so that I can install drivers from the internet instead of loading them on to a flash drive and doing it offline. If anyone has any insight to the problem, that would be awesome. If not, I'll probably just look up how to install the Windows closed source driver. Edit 1: Even when I try the method here, as suggested when this was marked as a duplicate, I still can't stay connected to a wireless network. Edit 2: After discussing my issue with @Luis, he opened my question back up and told me to include the tests/procedures in the comments. Basically I did this: Read the first answer of the link above when this question was marked as duplicate which involved installing removing bcmwl-kernel-source and instead install firmware-b43-installer and b43-fwcutter. No change of result and contacted Luis in the comments, who then told me to try the second answer which involved removing my previous mistake and installing bcmwl-kernel-source Now the Network Manger (this has happend before, but usally I fixed it by using a different driver) even recognizes WiFi exist (both non-literal and literal). Luis who then suggested sudo rfkill unblock all rfkill unblock all didn't return anything, so I decide to try sudo rfkill list all. Returns nothing (no wonder rfkill unblock all did nothing). I enter lsmod | grep "brcmsmac\|b43\|ssb\|bcma\|wl" and that returns nothing. Try loading the driver by entering sudo modprobe b43 and try lsmod | grep "brcmsmac\|b43\|ssb\|bcma\|wl" again. Returns this: eugene@Eugenes-uPC:~$ sudo modprobe b43 eugene@Eugenes-uPC:~$ lsmod | grep "brcmsmac\|b43\|ssb\|bcma\|wl" b43 387371 0 bcma 52096 1 b43 mac80211 630653 1 b43 cfg80211 484040 2 b43,mac80211 ssb_hcd 12869 0 ssb 62379 2 b43,ssb_hcd So to recap: Currently Network Manager doesn't recognize Wireless exists, b43 drivers are loaded and I've currently hardwired a connect from my laptop to the computer that's causing this.

• Using SQL Source Control and Vault Professional Part 4

  - by Ajarn Mark Caldwell

  Two weeks ago I upgraded our installation of Fortress to the latest version, which is now named Vault Professional.  This is the version of Vault (i.e. Vault Standard 5.1 / Vault Professional 5.1) that will be officially supported with Red-Gate SQL Source Control 2.1.  While the folks at Red-Gate did a fantastic job of working with me to get SQL Source Control to work with the older Fortress version, we weren’t going to just sit on that.  There are a couple of things that Vault Professional cleaned up for us, such as improved integration with Visual Studio 2010, so it was a win all around. Shortly after that upgrade, I received notice from Red-Gate that they had a new Early Access version of SQL Source Control available that included the ability to source control static data.  The idea here is that you probably have a few fairly static lookup tables in your system, and those data values are similar in concept to source code, and should be versioned in your source control management system also.  I agree with this, but please be wise…somebody out there is bound to try to use this feature as their disaster recovery for their entire database, and that is NOT the purpose.  First off, you should never have your PROD (or LIVE, whatever you call it) system attached to source control.  Source Control is for development, not for PROD systems.  Second, use the features that are intended for this purpose, such as BACKUP and RESTORE. Laying that tangent aside, it is great that now you can include these critical values in your repository and make them part of a deployment process.  As you would guess, SQL Source Control uses SQL Data Compare to create the data change scripts just like it uses SQL Compare to create the schema change scripts.  Once again, they did a very good job with the integration to their other products.  At this point we are really starting to see some good payback on our investment in the full SQL Developer Bundle.  Those products were worth the investment back when we only used them sporadically for troubleshooting and DBA analysis, but now with SQL Source Control, they are becoming everyday-use products for the development team. I like this software (SQL Source Control) so much that I am about to break my own rules and distribute it to my team to use even though it is still in beta.  This is the first time that I have approved the use of any beta software in a production scenario (actively building our next versions of internal software) but I predict that the usability and productivity gain of using SQL Source Control over manual scripting is worth the risk.  Of course, I have also put this beta software through its paces pretty well to be comfortable with it, and Red-Gate has proven their responsiveness to issues that came up in my early beta testing, and so I am willing to bet on their continued support.  Likewise, SourceGear, the maker of Vault Professional, has proven itself to me as well, and so the combination of SQL Source Control with Vault Professional is the new standard for my development team.

• When should complexity be removed?

  - by ElGringoGrande

  Prematurely introducing complexity by implementing design patterns before they are needed is not good practice. But if you follow all (or even most of) the SOLID principles and use common design patterns you will introduce some complexity as features and requirements are added or changed to keep your design as maintainable and flexible as needed. However once that complexity is introduced and working like a champ when do you removed it? Example. I have an application written for a client. When originally created there where several ways to give raises to employees. I used the strategy pattern and factory to keep the whole process nice and clean. Over time certain raise methods where added or removed by the application owner. Time passes and new owner takes over. This new owner is hard nosed, keeps everything simple and only has one single way to give a raise. The complexity needed by the strategy pattern is no longer needed. If I where to code this from the requirements as they are now I would not introduce this extra complexity (but make sure I could introduce it with little or no work should the need arise). So do I remove the strategy implementation now? I don't think this new owner will ever change how raises are given. But the application itself has demonstrated that this could happen. Of course this is just one example in an application where a new owner takes over and has simplified many processes. I could remove dozens of classes, interfaces and factories and make the whole application much more simple. Note that the current implementation does works just fine and the owner is happy with it (and surprised and even happier that I was able to implement her changes so quickly because of the discussed complexity). I admit that a small part of this doubt is because it is highly likely the new owner isn't going to use me any longer. I don't really care that somebody else will take this over since it has not been a big income generator. But I do care about 2 (related) things I care a bit that the new maintainer will have to think a bit harder when trying to understand the code. Complexity is complexity and I don't want to anger the psycho maniac coming after me. But even more I worry about a competitor seeing this complexity and thinking I just implement design patterns to pad my hours on jobs. Then spreading this rumor to hurt my other business. (I have heard this mentioned.) So... In general should previously needed complexity be removed even though it works and there has been a historically demonstrated need for the complexity but you have no indication that it will be needed in the future? Even if the question above is generally answered "no" is it wise to remove this "un-needed" complexity if handing off the project to a competitor (or stranger)?

• Hadoop growing pains

  - by Piotr Rodak

  This post is not going to be about SQL Server. I have been reading recently more and more about “Big Data” – very catchy term that describes untamed increase of the data that mankind is producing each day and the struggle to capture the meaning of these data. Ten years ago, and perhaps even three years ago this need was not so recognized. Increasing number of smartphones and discernable trend of mainstream Internet traffic moving to the smartphone generated one means that there is bigger and bigger stream of information that has to be stored, transformed, analysed and perhaps monetized. The nature of this traffic makes if very difficult to wrap it into boundaries of relational database engines. The amount of data makes it near to impossible to process them in relational databases within reasonable time. This is where ‘cloud’ technologies come to play. I just read a good article about the growing pains of Hadoop, which became one of the leading players on distributed processing arena within last year or two. Toby Baer concludes in it that lack of enterprise ready toolsets hinders Hadoop’s apprehension in the enterprise world. While this is true, something else drew my attention. According to the article there are already about half of a dozen of commercially supported distributions of Hadoop. For me, who has not been involved into intricacies of open-source world, this is quite interesting observation. On one hand, it is good that there is competition as it is beneficial in the end to the customer. On the other hand, the customer is faced with difficulty of choosing the right distribution. In future, when Hadoop distributions fork even more, this choice will be even harder. The distributions will have overlapping sets of features, yet will be quite incompatible with each other. I suppose it will take a few years until leaders emerge and the market will begin to resemble what we see in Linux world. There are myriads of distributions, but only few are acknowledged by the industry as enterprise standard. Others are honed by bearded individuals with too much time to spend. In any way, the third fact I can’t help but notice about the proliferation of distributions of Hadoop is that IT professionals will have jobs.   BuzzNet Tags: Hadoop,Big Data,Enterprise IT

• Refreshing imported MySQL data with MySQL for Excel

  - by Javier Rivera

  Welcome to another blog post from the MySQL for Excel Team. Today we're going to talk about a new feature included since MySQL for Excel 1.3.0, you can install the latest GA or maintenance version using the MySQL Installer or optionally you can download directly any GA or non-GA version from the MySQL Developer Zone.As some users suggested in our forums we should be maintaining the link between tables and Excel not only when editing data through the Edit MySQL Data option, but also when importing data via Import MySQL Data. Before 1.3.0 this process only provided you with an offline copy of the Table's data into Excel and you had no way to refresh that information from the DB later on. Now, with this new feature we'll show you how easy is to work with the latest available information at all times. This feature is transparent to you (it doesn't require additional steps to work as long as the users had the Create an Excel Table for the imported MySQL table data option enabled. To ensure you have this option checked, click over Advanced Options... after the Import Data dialog is displayed). The current blog post assumes you already know how to import data into excel, you could always take a look at our previous post How To - Guide to Importing Data from a MySQL Database to Excel using MySQL for Excel if you need further reference on that topic. After importing Data from a MySQL Table into Excel, you can refresh the data in 3 ways.1. Simply right click over the range of the imported data, to show the pop-up menu: Click over the Refresh button to obtain the latest copy of the data in the table. 2. Click the Refresh button on the Data ribbon: 3. Click the Refresh All button in the Data ribbon (beware this will refresh all Excel tables in the Workbook): Please take a note of a couple of details here, the first one is about the size of the table. If by the time you refresh the table new columns had been added to it, and you originally have imported all columns, the table will grow to the right. The same applies to rows, if the table has new rows and you did not limit the results , the table will grow to to the bottom of the sheet in Excel. The second detail you should take into account is this operation will overwrite any changes done to the cells after the table was originally imported or previously refreshed: Now with this new feature, imported data remains linked to the data source and is available to be updated at all times. It empowers the user to always be able to work with the latest version of the imported MySQL data. We hope you like this this new feature and give it a try! Remember that your feedback is very important for us, so drop us a message with your comments, suggestions for this or other features and follow us at our social media channels: MySQL on Windows (this) Blog: https://blogs.oracle.com/MySqlOnWindows/ MySQL for Excel forum: http://forums.mysql.com/list.php?172 Facebook: http://www.facebook.com/mysql YouTube channel: https://www.youtube.com/user/MySQLChannel Thanks!

• European e-government Action Plan all about interoperability

  - by trond-arne.undheim

  Yesterday, the European Commission released its European eGovernment Action Plan for 2011-2015. The plan includes measures on providing deeper user empowerment, enhancing the Internal Market, more efficiency and effectiveness of public administrations, and putting in place pre-conditions for developing e-government. The Good - Defines interoperability very clearly. Calls interoperability "a pre-condition for cross-border eGovernment services" (a very strong formulation) and says interoperability "is supported by open specifications". - Uses the terminology "open specifications" which, let's face it, is pretty close to "open standards" which is the term the rest of the world would use. - Confirms that Member States are fully committed to the political priorities of the Malmö Declaration (which was all about open standards) including the very strong action: by 2013: All Member States will have incorporated the political priorities of the Malmö Declaration in their national strategies. Such tight Action Plan integration between Commission and Member State priorities has seldom been attempted before, particularly not in a field where European legal competence is virtually non-existent. What we see now, is the subtle force of soft power rather than the rough force of regulation. In this case, it is the Member States who want Europe to take the lead. Very refreshing! Some quotes that show the commitment to interoperability and open specifications: "The emergence of innovative technologies such as "service-oriented architectures" (SOA), or "clouds" of services,  together with more open specifications which allow for greater sharing, re-use and interoperability reinforce the ability of ICT to play a key role in this quest for effficiency in the public sector." (p.4) "Interoperability is supported through open specifications" (p.13) 2.4.1. Open Specifications and Interoperability (p.13 has a whole section dedicated to this important topic. Open specifications and interoperability are nearly 100% interrelated): "Interoperability is the ability of systems and machines to exchange, process and correctly interpret information. It is more than just a technical challenge, as it also involves legal, organisational and semantic aspects of handling  data" (p.13) "standards and  open platforms offer opportunities for more cost-effective use of resources and delivery of services" (p.13). The Bad Shies away from defining open standards, or even open specifications, the EU's preferred term for the key enabler of interoperability. Verdict 90/100, a very respectable score.

• Forced Learning

  - by Ben Griswold

  If you ask me, it can be a little intimidating to stand in front of a group and walkthrough anything remotely technical. Even if you know “Technical Thingy #52” inside and out, public speaking can be unsettling.  And if you don’t have your stuff together, well, it can be downright horrifying. With that said, if given the choice, I still like to schedule myself to present on unfamiliar topics. Over the past few months, I’ve talked about Aspect-Oriented Programming, Functional Programming, Lean Software Development and Kanban Systems, Domain-Driven Design and Behavior Driven Development.  What do these topics have in common? You guessed it: I was truly interested in them. I had only a superficial understanding of each. Huh?  Why in the world would I ever want to to put myself in that intimidating situation? Actually, I rarely want to put myself into that situation but I often do as I like the results.  There’s nothing remotely clever going on here.  All I’m doing is putting myself into a compromising situation knowing that I’ll likely work myself out of it by learning the topic prior to the presentation.  I’m simply time-boxing myself to learn something new while knowing there are negative repercussions if I fall short. So, I end up doing tons of research and I learn bunches to ensure I have my head firmly wrap around the material before my talk. I’m not saying I become an expert overnight (or over a couple of weeks) but I’ll definitely know enough to be confident and comfortable and I’ll know more than enough to ensure the audience will learn a thing or two from me. It’s forced learning and though it might sound a little scary to some, it works for me. Now I could very easily rename this post to something like Fear Is My Motivator because, in a sense, fear of failure and embarrassment is what’s driving my learning. However, I’m the guy signing up for the presentation and since the entire process is self-imposed I’m not sure Fear deserves too much credit.  Anyway…

• SQL SERVER – Transaction Log Full – Transaction Log Larger than Data File – Notes from Fields #001

  - by Pinal Dave

  I am very excited to announce a new series on this blog – Notes from Fields. I have been blogging for almost 7 years on this blog and it has been a wonderful experience. Though, I have extensive experience with SQL and Databases, it is always a good idea that we consult experts for their advice and opinion. Following the same thought process, I have started this new series of Notes from Fields. In this series we will have notes from various experts in the database world. My friends at Linchpin People have graciously decided to support me in my new initiation.  Linchpin People are database coaches and wellness experts for a data driven world. In this very first episode of the Notes from Fields series database expert Tim Radney (partner at Linchpin People) explains a very common issue DBA and Developer faces in their career, when database logs fills up your hard-drive or your database log is larger than your data file. Read the experience of Tim in his own words. As a consultant, I encounter a number of common issues with clients.  One of the more common things I encounter is finding a user database in the FULL recovery model that does not make a regular transaction log backups or ever had a transaction log backup. When I find this, usually the transaction log is several times larger than the data file. Finding this issue is very significant to me in that it allows to me to discuss service level agreements with the client. I get to ask questions such as, are nightly full backups sufficient or do they need point in time recovery.  This conversation has now signed with the customer and gets them to thinking about their disaster recovery and high availability solutions. This issue is also very prominent on SQL Server forums and usually has the title of “Help, my transaction log has filled up my disk” or “Help, my transaction log is many times the size of my database”. In cases where the client only needs the previous full nights backup, I am able to change the recovery model to SIMPLE and shrink the transaction log using DBCC SHRINKFILE (2,1) or by specifying the transaction log file name by using DBCC SHRINKFILE (file_name, target_size). When the client needs point in time recovery then in most cases I will still end up switching the client to the SIMPLE recovery model to truncate the transaction log followed by a full backup. I will then schedule a SQL Agent job to make the regular transaction log backups with an interval determined by the client to meet their service level agreements. It should also be noted that typically when I find an overgrown transaction log the virtual log file count is also out of control. I clean up will always take that into account as well.  That is a subject for a future blog post. If your SQL Server is facing any issue we can Fix Your SQL Server.
