• BDD (Behavior-Driven Development) tools for .Net

  - by tikrimi

  For several years, I use TDD (Test-Driven Development) to produce code. I no longer plans to work without using TDD. The use of TDD significantly increases code quality, but does not guarantee that the code is the code that corresponds to the requirements specifications (write the "right code" with BDD as opposed to the write "code right" with BDD). Dan North has described in an article in published in 2006 the foundations of the BDD (Behavior-Driven Development). In this article, he introduces the formalism "When Given Then". This formalism is used in all tools dedicated to BDD. This is a short list of open source BDD tools that you can use with .Net : SpecFlow: Here you can find an article in MSDN Magazine and 2 webcasts (http://channel9.msdn.com/posts/ASPNET-MVC-With-Community-Tools-Part-2-Spec-Flow-and-WatiN and http://channel9.msdn.com/posts/ASPNET-MVC-With-Community-Tools-Part-3-More-Spec-Flow-and-WatiN) published on Chanel9. NSpec: This is certainly the most used project. There are many examples on the web. StoryQ: This project is hosted on Codeplex. This small project is very simple to implement and very useful.

• What happens when my domain provider cancels order after domain transfer?

  - by Saifur Rahman Mohsin

  I purchased 2 domains say xyz.in and abc.com on october 2012 and I got emails that they will be expiring on oct 2013. I called my local domain provider and told him I'd like to transfer the domain from Webiq to GoDaddy to which he said I cannot unless the domain is active. He asked me to pay for both the domains, renew it and then I could transfer the domain via the domain panel. When I went to the domain panel I noticed that the order was made and so I made a transfer which happened successfully. Just as he mentioned the period of validity (1 year) for each domain got transferred to GoDaddy as well! Additionally, I added 1 year of period to both the domain via GoDaddy so both of them and also GoDaddy provided an extra free year to both these domains as I paid for the transfer on 11/10/2013 at 9:18 PM MST so both of these were stated to be valid till 2016 and that's what it showed when I did a whois lookup as well. But now it suddenly shows me that my domains are getting expired this year (and the whois also shows 2015). This is confusing as I have no idea who to blame for the missing one year. I'm wondering what would have happened say if my old domain provider's client who got my domain registered cancelled the order. Since it was no longer under their control would they still be able to deduce that one year? When I tried submitting a support request to Webiq they replied: Your domain "abc.com" has been transferred away from us on 17-11-2013 and the domain "xyz.in" was transferred away from us on 18-01-2014. There are no order cancellation actions placed. If you have any billing related issues kindly contact your parent reseller. I need some guidance on explaining what issue might have occurred or understanding how this domain control works!

• Keystone Correction using 3D-Points of Kinect

  - by philllies

  With XNA, I am displaying a simple rectangle which is projected onto the floor. The projector can be placed at an arbitrary position. Obviously, the projected rectangle gets distorted according to the projectors position and angle. A Kinect scans the floor looking for the four corners. Now my goal is to transform the original rectangle such that the projection is no longer distorted by basically pre-warping the rectangle. My first approach was to do everything in 2D: First compute a perspective transformation (using OpenCV's warpPerspective()) from the scanned points to the internal rectangle's points und apply the inverse to the rectangle. This seemed to work but was too slow as it couldn't be rendered on the GPU. The second approach was to do everything in 3D in order to use XNA's rendering features. First, I would display a plane, scan its corners with Kinect and map the received 3D-Points to the original plane. Theoretically, I could apply the inverse of the perspective transformation to the plane, as I did in the 2D-approach. However, in since XNA works with a view and projection matrix, I can't just call a function such as warpPerspective() and get the desired result. I would need to compute the new parameters for the camera's view and projection matrix. Question: Is it possible to compute these parameters and split them into two matrices (view and projection)? If not, is there another approach I could use?

• Oracle IRM video demonstration of seperating duties of document security

  - by Simon Thorpe

  One thing an Information Rights Management technology should do well is separate out three main areas of responsibility.The business process of defining and controlling the classifications to which content is secured and the definition of the roles employees, customers, partners and contractors have when accessing secured content. Allow IT to manage the server and perform the role of authorizing the creation of new classifications to meet business needs but yet once the classification has been created and handed off to the business, IT no longer plays a role on the ongoing management. Empower the business to take ownership of classifications to which their own content is secured. For example an employee who is leading an acquisition project should be responsible for defining who has access to confidential project documents. This person should be able to manage the rights users have in the classification and also be the point of contact for those wishing to gain rights. Oracle IRM has since it's creation in the late 1990's had this core model at the heart of its design. Due in part to the important seperation of rights from the documents themselves, Oracle IRM places the right functionality within the right parts of the business. For example some IRM technologies allow the end user to make decisions about what users can print, edit or save a secured document. This in practice results in a wide variety of content secured with a plethora of options that don't conform to any policy. With Oracle IRM users choose from a list of classifications to which they have been given the ability to secure information against. Their role in the classification was given to them by the business owner of the classification, yet the definition of the role resides within the realm of corporate security who own the overall business classification policies. It is this type of design and philosophy in Oracle IRM that makes it an enterprise solution that works beyond a few users and a few secured documents to hundreds of thousands of users and millions of documents. This following video shows how Oracle IRM 11g, the market leading document security solution, lets the security organization manage and create classifications whilst the business owns and manages them. If you want to experience using Oracle IRM secured content and the effects of different roles users have, why not sign up for our free demonstration.

• Seamless Mode Not Working Correctly in Virtual Box

  - by Jeremy

  I run Ubuntu Desktop in a VirtualBox seamless mode, hosted on Windows 7. I recently upgraded from 11.10 to 12.04 and seamless mode no longer works correctly. I have re-installed guest extensions. The problem is that the Ubuntu desktop wallpaper is shown, effectively blocking the Windows desktop. I can bring Windows apps to the foreground, but as soon as I bring any Ubuntu window to the foreground, all the windows apps will disappear, hidden by the ubuntu desktop even if I activated an Ubuntu window in a different monitor. So, it is not very much different from full-screen mode at this time. I suspect if I could turn off the Ubuntu desktop or wallpaper this would be a sufficient workaround (this is basically what Seamless mode is) but that does not seem to be possible within Ubuntu itself. [Jeremy doesn't specify system config, but I can confirm I'm seeing this behavior in Win 7 64-bit with both 32-bit and 64-bit guests. Giovanni sees the same thing on his laptop running Vista Ultimate 64 bit after upgrading his 32-bit guest to 12.04 (forums.virtualbox.org p225407, requires logging in with your free Oracle account). I was using vbox 4.1.14r77440 and matching Guest Additions. I upgraded to 4.1.16-78094 vbox+additions. Still a problem. And I filed launchpad bug 999929 to see if I can get feedback from developers. – tbc0] Any other ideas?

• Whew.... what a week!

  - by [email protected]

  Last week was a busy week for the UPK and Tutor teams at Oracle. It started with the the Collaborate Conference in Las Vegas and ended with our first UPK and Tutor Customer Advisory Board (CAB) meeting at Oracle HQ. The Collaborate Conference is a yearly event sponsored by three of the largest Oracle User Groups. • Oracle Applications User Group (OAUG) • Independent Oracle User Group (IOUG) • Quest - International User Group The User Groups are completely user run organizations with Oracle participation. If you've never attended a conference, time to start planning for the 2011 event in Orlando! If that's out of your reach, there are many regional and industry user groups that meet on a regular basis. They offer a great way to get involved, network with other users, and increase your knowledge around the Oracle applications. For a list of groups near you, check out the Oracle User Group Center. I'll add that the biggest meeting of Oracle users is at the Oracle Open World Conference in San Francisco in September, where we will have many UPK & Tutor focused development and customer sessions. More information on Oracle Open World will be forthcoming over the next few months. We hope to see many of you there! The CAB was a first for the UPK and Tutor team. Although we speak with customers regularly, this gave us an opportunity to meet in a more formal setting to discuss industry trends, business issues, and the direction of the products. Members serve a 2 year term and are required to attend 2 meetings per year, one in person, one via phone. We have some tweaking to do to our meeting format (most members wanted it to be longer!), but the overwhelming consensus was that it was a great success. There were many experiences and ideas shared and the wheels of the UPK and Tutor Development teams have been turning ever since. I'm sure you will see some of these discussions result in new product features over time. What a great week!

• Understanding C# async / await (2) Awaitable / Awaiter Pattern

  - by Dixin

  What is awaitable Part 1 shows that any Task is awaitable. Actually there are other awaitable types. Here is an example: Task<int> task = new Task<int>(() => 0); int result = await task.ConfigureAwait(false); // Returns a ConfiguredTaskAwaitable<TResult>. The returned ConfiguredTaskAwaitable<TResult> struct is awaitable. And it is not Task at all: public struct ConfiguredTaskAwaitable<TResult> { private readonly ConfiguredTaskAwaiter m_configuredTaskAwaiter; internal ConfiguredTaskAwaitable(Task<TResult> task, bool continueOnCapturedContext) { this.m_configuredTaskAwaiter = new ConfiguredTaskAwaiter(task, continueOnCapturedContext); } public ConfiguredTaskAwaiter GetAwaiter() { return this.m_configuredTaskAwaiter; } } It has one GetAwaiter() method. Actually in part 1 we have seen that Task has GetAwaiter() method too: public class Task { public TaskAwaiter GetAwaiter() { return new TaskAwaiter(this); } } public class Task<TResult> : Task { public new TaskAwaiter<TResult> GetAwaiter() { return new TaskAwaiter<TResult>(this); } } Task.Yield() is a another example: await Task.Yield(); // Returns a YieldAwaitable. The returned YieldAwaitable is not Task either: public struct YieldAwaitable { public YieldAwaiter GetAwaiter() { return default(YieldAwaiter); } } Again, it just has one GetAwaiter() method. In this article, we will look at what is awaitable. The awaitable / awaiter pattern By observing different awaitable / awaiter types, we can tell that an object is awaitable if It has a GetAwaiter() method (instance method or extension method); Its GetAwaiter() method returns an awaiter. An object is an awaiter if: It implements INotifyCompletion or ICriticalNotifyCompletion interface; It has an IsCompleted, which has a getter and returns a Boolean; it has a GetResult() method, which returns void, or a result. This awaitable / awaiter pattern is very similar to the iteratable / iterator pattern. Here is the interface definitions of iteratable / iterator: public interface IEnumerable { IEnumerator GetEnumerator(); } public interface IEnumerator { object Current { get; } bool MoveNext(); void Reset(); } public interface IEnumerable<out T> : IEnumerable { IEnumerator<T> GetEnumerator(); } public interface IEnumerator<out T> : IDisposable, IEnumerator { T Current { get; } } In case you are not familiar with the out keyword, please find out the explanation in Understanding C# Covariance And Contravariance (2) Interfaces. The “missing” IAwaitable / IAwaiter interfaces Similar to IEnumerable and IEnumerator interfaces, awaitable / awaiter can be visualized by IAwaitable / IAwaiter interfaces too. This is the non-generic version: public interface IAwaitable { IAwaiter GetAwaiter(); } public interface IAwaiter : INotifyCompletion // or ICriticalNotifyCompletion { // INotifyCompletion has one method: void OnCompleted(Action continuation); // ICriticalNotifyCompletion implements INotifyCompletion, // also has this method: void UnsafeOnCompleted(Action continuation); bool IsCompleted { get; } void GetResult(); } Please notice GetResult() returns void here. Task.GetAwaiter() / TaskAwaiter.GetResult() is of such case. And this is the generic version: public interface IAwaitable<out TResult> { IAwaiter<TResult> GetAwaiter(); } public interface IAwaiter<out TResult> : INotifyCompletion // or ICriticalNotifyCompletion { bool IsCompleted { get; } TResult GetResult(); } Here the only difference is, GetResult() return a result. Task<TResult>.GetAwaiter() / TaskAwaiter<TResult>.GetResult() is of this case. Please notice .NET does not define these IAwaitable / IAwaiter interfaces at all. As an UI designer, I guess the reason is, IAwaitable interface will constraint GetAwaiter() to be instance method. Actually C# supports both GetAwaiter() instance method and GetAwaiter() extension method. Here I use these interfaces only for better visualizing what is awaitable / awaiter. Now, if looking at above ConfiguredTaskAwaitable / ConfiguredTaskAwaiter, YieldAwaitable / YieldAwaiter, Task / TaskAwaiter pairs again, they all “implicitly” implement these “missing” IAwaitable / IAwaiter interfaces. In the next part, we will see how to implement awaitable / awaiter. Await any function / action In C# await cannot be used with lambda. This code: int result = await (() => 0); will cause a compiler error: Cannot await 'lambda expression' This is easy to understand because this lambda expression (() => 0) may be a function or a expression tree. Obviously we mean function here, and we can tell compiler in this way: int result = await new Func<int>(() => 0); It causes an different error: Cannot await 'System.Func<int>' OK, now the compiler is complaining the type instead of syntax. With the understanding of the awaitable / awaiter pattern, Func<TResult> type can be easily made into awaitable. GetAwaiter() instance method, using IAwaitable / IAwaiter interfaces First, similar to above ConfiguredTaskAwaitable<TResult>, a FuncAwaitable<TResult> can be implemented to wrap Func<TResult>: internal struct FuncAwaitable<TResult> : IAwaitable<TResult> { private readonly Func<TResult> function; public FuncAwaitable(Func<TResult> function) { this.function = function; } public IAwaiter<TResult> GetAwaiter() { return new FuncAwaiter<TResult>(this.function); } } FuncAwaitable<TResult> wrapper is used to implement IAwaitable<TResult>, so it has one instance method, GetAwaiter(), which returns a IAwaiter<TResult>, which wraps that Func<TResult> too. FuncAwaiter<TResult> is used to implement IAwaiter<TResult>: public struct FuncAwaiter<TResult> : IAwaiter<TResult> { private readonly Task<TResult> task; public FuncAwaiter(Func<TResult> function) { this.task = new Task<TResult>(function); this.task.Start(); } bool IAwaiter<TResult>.IsCompleted { get { return this.task.IsCompleted; } } TResult IAwaiter<TResult>.GetResult() { return this.task.Result; } void INotifyCompletion.OnCompleted(Action continuation) { new Task(continuation).Start(); } } Now a function can be awaited in this way: int result = await new FuncAwaitable<int>(() => 0); GetAwaiter() extension method As IAwaitable shows, all that an awaitable needs is just a GetAwaiter() method. In above code, FuncAwaitable<TResult> is created as a wrapper of Func<TResult> and implements IAwaitable<TResult>, so that there is a  GetAwaiter() instance method. If a GetAwaiter() extension method  can be defined for Func<TResult>, then FuncAwaitable<TResult> is no longer needed: public static class FuncExtensions { public static IAwaiter<TResult> GetAwaiter<TResult>(this Func<TResult> function) { return new FuncAwaiter<TResult>(function); } } So a Func<TResult> function can be directly awaited: int result = await new Func<int>(() => 0); Using the existing awaitable / awaiter - Task / TaskAwaiter Remember the most frequently used awaitable / awaiter - Task / TaskAwaiter. With Task / TaskAwaiter, FuncAwaitable / FuncAwaiter are no longer needed: public static class FuncExtensions { public static TaskAwaiter<TResult> GetAwaiter<TResult>(this Func<TResult> function) { Task<TResult> task = new Task<TResult>(function); task.Start(); return task.GetAwaiter(); // Returns a TaskAwaiter<TResult>. } } Similarly, with this extension method: public static class ActionExtensions { public static TaskAwaiter GetAwaiter(this Action action) { Task task = new Task(action); task.Start(); return task.GetAwaiter(); // Returns a TaskAwaiter. } } an action can be awaited as well: await new Action(() => { }); Now any function / action can be awaited: await new Action(() => HelperMethods.IO()); // or: await new Action(HelperMethods.IO); If function / action has parameter(s), closure can be used: int arg0 = 0; int arg1 = 1; int result = await new Action(() => HelperMethods.IO(arg0, arg1)); Using Task.Run() The above code is used to demonstrate how awaitable / awaiter can be implemented. Because it is a common scenario to await a function / action, so .NET provides a built-in API: Task.Run(): public class Task2 { public static Task Run(Action action) { // The implementation is similar to: Task task = new Task(action); task.Start(); return task; } public static Task<TResult> Run<TResult>(Func<TResult> function) { // The implementation is similar to: Task<TResult> task = new Task<TResult>(function); task.Start(); return task; } } In reality, this is how we await a function: int result = await Task.Run(() => HelperMethods.IO(arg0, arg1)); and await a action: await Task.Run(() => HelperMethods.IO());

• Going Paperless

  - by Jesse

  One year ago I came to work for a company where the entire development team is 100% “remote”; we’re spread over 3 time zones and each of us works from home. This seems to be an increasingly popular way for people to work and there are many articles and blog posts out there enumerating the advantages and disadvantages of working this way. I had read a lot about telecommuting before accepting this job and felt as if I had a pretty decent idea of what I was getting into, but I’ve encountered a few things over the past year that I did not expect. Among the most surprising by-products of working from home for me has been a dramatic reduction in the amount of paper that I use on a weekly basis. Hoarding In The Workplace Prior to my current telecommute job I worked in what most would consider pretty traditional office environments. I sat in cubicles furnished with an enormous plastic(ish) modular desks, had a mediocre (at best) PC workstation, and had ready access to a seemingly endless supply of legal pads, pens, staplers and paper clips. The ready access to paper, countless conference room meetings, and abundance of available surface area on my desk and in drawers created a perfect storm for wasting paper. I brought a pad of paper with me to every meeting I ever attended, scrawled some brief notes, and then tore that sheet off to keep next to my keyboard to follow up on any needed action items. Once my immediate need for the notes was fulfilled, that sheet would get shuffled off into a corner of my desk or filed away in a drawer “just in case”. I would guess that for all of the notes that I ever filed away, I might have actually had to dig up and refer to 2% of them (and that’s probably being very generous). That said, on those rare occasions that I did have to dig something up from old notes, it was usually pretty important and I ended up being very glad that I saved them. It was only when I would leave a job or move desks that I would finally gather all those notes together and take them to shredding bin to be disposed of. When I left my last job the amount of paper I had accumulated over my three years there was absurd, and I knew coworkers who had substance-abuse caliber paper wasting addictions that made my bad habit look like nail-biting in comparison. A Product Of My Environment I always hated using all of this paper, but simply couldn’t bring myself to stop. It would look bad if I showed up to an important conference room meeting without a pad of paper. What if someone said something profound! Plus, everyone else always brought paper with them. If you saw someone walking down the hallway with a pad of paper in hand you knew they must be on their way to a conference room meeting. Some people even had fancy looking portfolio notebook sheaths that gave their legal pads all the prestige of a briefcase. No one ever worried about running out of fresh paper because there was an endless supply, and there certainly was no shortage of places to store and file used paper. In short, the traditional office was setup for using tons and tons of paper; it’s baked into the culture there. For that reason, it didn’t take long for me to kick the paper habit once I started working from home. In my home office, desk and drawer space are at a premium. I don’t have the budget (or the tolerance) for huge modular office furniture in my spare bedroom. I also no longer have access to a bottomless pit of office supplies stock piled in cabinets and closets. If I want to use some paper, I have to go out and buy it. Finally (and most importantly), all of the meetings that I have to attend these days are “virtual”. We use instant messaging, VOIP, video conferencing, and e-mail to communicate with each other. All I need to take notes during a meeting is my computer, which I happen to be sitting right in front of all day. I don’t have any hard numbers for this, but my gut feeling is that I actually take a lot more notes now than I ever did when I worked in an office. The big difference is I don’t have to use any paper to do so. This makes it far easier to keep important information safe and organized. The Right Tool For The Job When I first started working from home I tried to find a single application that would fill the gap left by the pen and paper that I always had at my desk when I worked in an office. Well, there are no silver bullets and I’ve evolved my approach over time to try and find the best tool for the job at hand. Here’s a quick summary of how I take notes and keep everything organized. Notepad++ – This is the first application I turn to when I feel like there’s some bit of information that I need to write down and save. I use Launchy, so opening Notepad++ and creating a new file only takes a few keystrokes. If I find that the information I’m trying to get down requires a more sophisticated application I escalate as needed. The Desktop – By default, I save every file or other bit of information to the desktop. Anyone who has ever had to fix their parents computer before knows that this is a dangerous game (any file my mother has ever worked on is saved directly to the desktop and rarely moves anywhere else). I agree that storing things on the desktop isn’t a great long term approach to keeping organized, which is why I treat my desktop a bit like my e-mail inbox. I strive to keep both empty (or as close to empty as I possibly can). If something is on my desktop, it means that it’s something relevant to a task or project that I’m currently working on. About once a week I take things that I’m not longer working on and put them into my ‘Notes’ folder. The ‘Notes’ Folder – As I work on a task, I tend to accumulate multiple files associated with that task. For example, I might have a bit of SQL that I’m working on to gather data for a new report, a quick C# method that I came up with but am not yet ready to commit to source control, a bulleted list of to-do items in a .txt file, etc. If the desktop starts to get too cluttered, I create a new sub-folder in my ‘Notes’ folder. Each sub-folder’s name is the current date followed by a brief description of the task or project. Then all files related to that task or project go into that sub folder. By using the date as the first part of the folder name, these folders are automatically sorted in reverse chronological order. This means that things I worked on recently will generally be near the top of the list. Using the built-in Windows search functionality I now have a pretty quick and easy way to try and find something that I worked on a week ago or six months ago. Dropbox – Dropbox is a free service that lets you store up to 2GB of files “in the cloud” and have those files synced to all of the different computers that you use. My ‘Notes’ folder lives in Dropbox, meaning that it’s contents are constantly backed up and are always available to me regardless of which computer I’m using. They also have a pretty decent iPhone application that lets you browse and view all of the files that you have stored there. The free 2GB edition is probably enough for just storing notes, but I also pay $99/year for the 50GB storage upgrade and keep all of my music, e-books, pictures, and documents in Dropbox. It’s a fantastic service and I highly recommend it. Evernote – I use Evernote mostly to organize information that I access on a fairly regular basis. For example, my Evernote account has a running grocery shopping list, recipes that my wife and I use a lot, and contact information for people I contact infrequently enough that I don’t want to keep them in my phone. I know some people that keep nearly everything in Evernote, but there’s something about it that I find a bit clunky, so I tend to use it sparingly. Google Tasks – One of my biggest paper wasting habits was keeping a running task-list next to my computer at work. Every morning I would sit down, look at my task list, cross off what was done and add new tasks that I thought of during my morning commute. This usually resulted in having to re-copy the task list onto a fresh sheet of paper when I was done. I still keep a running task list at my desk, but I’ve started using Google Tasks instead. This is a dead-simple web-based application for quickly adding, deleting, and organizing tasks in a simple checklist style. You can quickly move tasks up and down on the list (which I use for prioritizing), and even create sub-tasks for breaking down larger tasks into smaller pieces. Balsamiq Mockups – This is a simple and lightweight tool for creating drawings of user interfaces. It’s great for sketching out a new feature, brainstorm the layout of a interface, or even draw up a quick sequence diagram. I’m terrible at drawing, so Balsamiq Mockups not only lets me create sketches that other people can actually understand, but it’s also handy because you can upload a sketch to a common location for other team members to access. I can honestly say that using these tools (and having limited resources at home) have lead me to cut my paper usage down to virtually none. If I ever were to return to a traditional office workplace (hopefully never!) I’d try to employ as many of these applications and techniques as I could to keep paper usage low. I feel far less cluttered and far better organized now.

• Announcing Unbreakable Enterprise Kernel Release 3 for Oracle Linux

  - by Lenz Grimmer

  We are excited to announce the general availability of the Unbreakable Enterprise Kernel Release 3 for Oracle Linux 6. The Unbreakable Enterprise Kernel Release 3 (UEK R3) is Oracle's third major supported release of its heavily tested and optimized Linux kernel for Oracle Linux 6 on the x86_64 architecture. UEK R3 is based on mainline Linux version 3.8.13. Some notable highlights of this release include: Inclusion of DTrace for Linux into the kernel (no longer a separate kernel image). DTrace for Linux now supports probes for user-space statically defined tracing (USDT) in programs that have been modified to include embedded static probe points Production support for Linux containers (LXC) which were previously released as a technology preview Btrfs file system improvements (subvolume-aware quota groups, cross-subvolume reflinks, btrfs send/receive to transfer file system snapshots or incremental differences, file hole punching, hot-replacing of failed disk devices, device statistics) Improved support for Control Groups (cgroups)  The ext4 file system can now store the content of a small file inside the inode (inline_data) TCP fast open (TFO) can speed up the opening of successive TCP connections between two endpoints FUSE file system performance improvements on NUMA systems Support for the Intel Ivy Bridge (IVB) processor family Integration of the OpenFabrics Enterprise Distribution (OFED) 2.0 stack, supporting a wide range of Infinband protocols including updates to Oracle's Reliable Datagram Sockets (RDS) Numerous driver updates in close coordination with our hardware partners UEK R3 uses the same versioning model as the mainline Linux kernel version. Unlike in UEK R2 (which identifies itself as version "2.6.39", even though it is based on mainline Linux 3.0.x), "uname" returns the actual version number (3.8.13). For further details on the new features, changes and any known issues, please consult the Release Notes. The Unbreakable Enterprise Kernel Release 3 and related packages can be installed using the yum package management tool on Oracle Linux 6 Update 4 or newer, both from the Unbreakable Linux Network (ULN) and our public yum server. Please follow the installation instructions in the Release Notes for a detailed description of the steps involved. The kernel source tree will also available via the git source code revision control system from https://oss.oracle.com/git/?p=linux-uek3-3.8.git If you would like to discuss your experiences with Oracle Linux and UEK R3, we look forward to your feedback on our public Oracle Linux Forum.

• Interactive Reporting with BI Publisher 11G

  - by kanichiro.nishida

  One of the new features that came out with BI Publisher 11G and made me really excited about is the Interactive Viewer, which allows you to interact with the data presented in the reports and gain more insights about the data. You can have as many Table, Chart, Pivot Table, Gauge components in a single report and all of them are linked together so that you can click on any data point on the components such as Chart, Pivot Table, Gauge, and that would refresh other components in the report to reflect the selection without refreshing the whole report or page. No longer you need to navigate to another report or open other reports to see related data or drill down to the detail data. It’s all there within a single report. Well, sounds cliché but really this is a typical case of ‘seeing is believing’, so instead of reading I would love you guys to take a look so I’ve recorded the following video. Please take a look !   The above video shows you the power of the BI Publisher Interactive Viewer with a real data from San Francisco Airport. The lists shown at the top or the left are one of the new features that we’ll be introducing in coming future very soon, but everything else is there with 11.1.1.3. So why not start today ? And please share your feedback with us!

• Are project managers useful in Scrum?

  - by Martin Wickman

  There are three roles defined in Scrum: Team, Product Owner and Scrum Master. There is no project manager, instead the project manager job is spread across the three roles. For instance: The Scrum Master: Responsible for the process. Removes impediments. The Product Owner: Manages and prioritizes the list of work to be done to maximize ROI. Represents all interested parties (customers, stakeholders). The Team: Self manage its work by estimating and distributing it among themselves. Responsible for meeting their own commitments. So in Scrum, there is no longer a single person responsible for project success. There is no command-and-control structure in place. That seems to baffle a lot of people, specifically those not used to agile methods, and of course, PM's. I'm really interested in this and what your experiences are, as I think this is one of the things that can make or break a Scrum implementation. Do you agree with Scrum that a project manager is not needed? Do you think such a role is still required? Why?

• Shockwave Flash crashes with Chromium and Firefox

  - by Stephan

• How do you use blank lines in your code ?

  - by Matthieu M.

  There has been a few remarks about white space already in discussion about curly braces placements. I myself tend to sprinkle my code with blank lines in an attempt to segregate things that go together in "logical" groups and hopefully make it easier for the next person to come by to read the code I just produced. In fact, I would say I structure my code like I write: I make paragraphs, no longer than a few lines (definitely shorter than 10), and try to make each paragraph self-contained. For example: in a class, I will group methods that go together, while separating them by a blank line from the next group. if I need to write a comment I'll usually put a blank line before the comment in a method, I make one paragraph per step of the process All in all, I rarely have more than 4/5 lines clustered together, meaning a very sparse code. I don't consider all this white space a waste because I actually use it to structure the code (as I use the indentation in fact), and therefore I feel it worth the screen estate it takes. For example: for (int i = 0; i < 10; ++i) { if (i % 3 == 0) continue; array[i] += 2; } I consider than the two statements have clear distinct purposes and thus deserve to be separated to make it obvious. So, how do you actually use (or not) blank lines in code ?

• The Cloud is STILL too slow!

  - by harry.foxwell(at)oracle.com

  If you've been in the computing industry sufficiently long enough to remember dialup modems and other "ancient" technologies, you might be tempted to marvel at today's wonderfully powerful multicore PCs, ginormous disks, and blazingly fast networks.  Wow, you're in Internet Nirvana, right!  Well, no, not by a long shot.Considering the exponentially growing expectations of what the Web, that is, "the Cloud", is supposed to provide, today's Web/Cloud services are still way too slow.Already we are seeing cloud-enabled consumer devices that are stressing even the most advanced public network services.  Like the iPad and its competitors, ever more powerful smart-phones, and an imminent hoard of special purpose gadgets such as the proposed "cloud camera" (see http://gdgt.com/discuss/it-time-cloud-camera-found-out-cnr/ ).And at the same time that the number and type of cloud services are growing, user tolerance for even the slightest of download delays is rapidly decreasing.  Ten years ago Web developers followed the "8-Second Rule", (average time a typical Web user would tolerate for a page to download and render).  Not anymore; now it's less than 3 seconds, and only a bit longer for mobile devices (see http://www.technologyreview.com/files/54902/GoogleSpeed_charts.pdf).  How spoiled we've become!Google, among others, recognizes this problem and is working to encourage the development of a faster Web (see http://www.technologyreview.com/web/32338/). They, along with their competitors and ISPs, will have to encourage and support significantly better Web performance in order to provide the types of services envisioned for the Cloud.  How will they do this? Through the development of faster components, better use of caching technologies, and the really tough one - exploiting parallelism. Not that parallel technologies like multicore processors are hard to build...we already have them.  It's just that we're not that good yet at using them effectively.  And if we don't get better, users will abandon cloud-based services...in less than 3 seconds.

• How can I reinstall XRandR without serious disruption to 12.04?

  - by broiyan

  This is the sequence that leads to xrandr going missing: Installed 12.04 on a system with a motherboard using the Intel G45 chipset and the E8400 Core 2 Duo and AMD Radeon HD 5450 video card. Installed fglrx when ubuntu prompted via Additional Drivers. Ran Catalyst (Administrative) to select multi-desktop and rebooted. Ran Catalyst (Administrative) to select Xinerama and rebooted. Answer yes to about 3 prompts that request to send bug reports to ubuntu. At this point Settings > Appearances no longer offers the widget that allows you to resize the Unity Launcher icons. Also Settings > Displays says randr extension is not present. BTW: This same sequence is repeatable, including the issues with the missing icon resizer and xrandr, so there is clearly bug fixing potential here. How can I get xrandr reinstalled without un-installing a large set of dependencies? I realize that if I un-install xrandr I will have the chance to re-install but the number of dependencies is large and so an un-install will cause many systems to be un-installed and I am afraid that will ruin Ubuntu 12.04. Hence, I'm looking for a more direct fix. I thought rebooting the .ISO disk and reinstalling would be a good fix but obviously not since this problem is repeatable.

• Getting SQL table row counts via sysindexes vs. sys.indexes

  - by Bill Osuch

  Among the many useful SQL snippets I regularly use is this little bit that will return row counts in a table: SELECT so.name as TableName, MAX(si.rows) as [RowCount] FROM sysobjects so JOIN sysindexes si ON si.id = OBJECT_ID(so.name) WHERE so.xtype = 'U' GROUP BY so.name ORDER BY [RowCount] DESC This is handy to find tables that have grown wildly, zero-row tables that could (possibly) be dropped, or other clues into the data. Right off the bat you may spot some "non-ideal" code - I'm using sysobjects rather than sys.objects. What's the difference? In SQL Server 2005 and later, sysobjects is no longer a table, but a "compatibility view", meant for backward compatibility only. SELECT * from each and you'll see the different data that each returns. Microsoft advises that sysindexes could be removed in a future version of SQL Server, but this has never really been an issue for me since my company is still using SQL 2000. However, there are murmurs that we may actually migrate to 2008 some year, so I might as well go ahead and start using an updated version of this snippet on the servers that can handle it: SELECT so.name as TableName, ddps.row_count as [RowCount] FROM sys.objects so JOIN sys.indexes si ON si.OBJECT_ID = so.OBJECT_ID JOIN sys.dm_db_partition_stats AS ddps ON si.OBJECT_ID = ddps.OBJECT_ID  AND si.index_id = ddps.index_id WHERE si.index_id < 2  AND so.is_ms_shipped = 0 ORDER BY ddps.row_count DESC

• Planning for the Recovery

  - by john.orourke(at)oracle.com

  As we plan for 2011, there are many positive signs in the global economy, but also some lingering issues. Planning no longer is about extrapolating past performance and adjusting for growth. It is now about constantly testing the temperature of the water, formulating scenarios, assessing risk and assigning probabilities.  So how does one plan for recovery and improve forecast accuracy in such a volatile environment?  Here are some suggestions from a recent article I wrote, which was published in the December Financial Planning & Analysis (FP&A) newsletter from the AFP (Association of Financial Professionals): Increase the frequency of forecasting Get more line managers involved in the planning and forecasting process Re-consider what's being measured - i.e. key financial and operational metrics Incorporate risk and probability into forecasts Reduce reliance on spreadsheets - leverage packaged EPM applications To learn more about these best practices, check out the FP&A section of the AFP website and register to receive the FP&A newsletter.  AFP recently launched a new topic area focused on the FP&A function and items of interest to this group of finance professionals.  In addition to the FP&A quarterly newsletter, AFP will be publishing articles, running webinars and will have an FP&A track in their annual conference, which is in Boston next November.  Brian Kalish, AFP's Finance Lead, is hoping this initiative creates a valuable networking and information-sharing resource for FP&A professionals. Here's a link to the FP&A page on the AFP web site:  http://www.afponline.org/pub/res/topics/topics_fpa.html If you register on the site you can access and subscribe to the FP&A newsletter and other resources. Best of luck in your planning for 2011 and beyond!

• How to install OpenCV without nVidia drivers

  - by Subhamoy Sengupta

  I have a laptop with on-board Intel graphics. I have been using OpenCV for years with this machine and I have managed to avoid manual compilation so far. But in Ubuntu 13.10, when I try to install libopencv-dev from the repositories, it brings along libopencv-ocl, which seems to be dependent on nvidia drivers. Letting the driver install messes up my xserver completely and when I do glxinfo afterwards, I get this: name of display: :0.0 Xlib: extension "GLX" missing on display ":0.0". Xlib: extension "GLX" missing on display ":0.0". Xlib: extension "GLX" missing on display ":0.0". Xlib: extension "GLX" missing on display ":0.0". Xlib: extension "GLX" missing on display ":0.0". Error: couldn't find RGB GLX visual or fbconfig Xlib: extension "GLX" missing on display ":0.0". Xlib: extension "GLX" missing on display ":0.0". Xlib: extension "GLX" missing on display ":0.0". Xlib: extension "GLX" missing on display ":0.0". Xlib: extension "GLX" missing on display ":0.0". Xlib: extension "GLX" missing on display ":0.0". Xlib: extension "GLX" missing on display ":0.0". To solve this, I purge all nVidia drivers and reinstall xserver, much like it has been suggested here, and when I purge the nvidia drivers, OpenCV development libraries are also removed, as apt-get tells me they are no longer needed. This is foreign to me, because I expected a warning that I have installed packages that depend on this, but how can removing a dependency automatically remove the package I installed without warnings or asking? I understand it has something to do with nVidia being the provider of the libopencv-ocl in the repo. How could I get around it? I would rather not compile OpenCV if I can help it. I have seen similar questions, but not a suitable answer.

• What's the term for re-implementing an old API in terms of a newer API

  - by dodgy_coder

  The reason for doing it is to solve the case when a newer API is no longer backwards compatible with an older API. To explain, just say that there is an old API v1.0. The maker of this API decides it is broken and works on a new API v1.1 that intentionally breaks compatibility with the old API v1.0. Now, any programs written against the old API cannot be recompiled as-is with the new API. Then lets say there is a large app written against the old API and the developer doesn't have access to the source code. A solution would be to re-implement a "custom" old API v1.0 in terms of the new API v1.1 calls. So the "custom" v1.0 API is actually keeping the same interface/methods as the v1.0 API but inside its implementation it is actually making calls to the new API v1.1 methods. So the large app can be then compiled and linked against the "custom" v1.0 API and the new v1.1 API without any major source code changes. Is there a term for this practice? There's a recent example of this happening in Jamie Zawinski's port of XScreenSaver to the iPhone - he re-implemented the OpenGL 1.3 API in terms of the OpenGL ES 1.1 API. In this case, OpenGL 1.3 represents the "old" API and OpenGL ES 1.1 represents the "new" API.

• Exalogic&ndash;The One Day Installation Challenge

  - by james.bayer

  It’s a really exciting time for the extended WebLogic community as we are enjoying seeing the impressive results of Exalogic deployments.  At Oracle Open World, a lot of people I spoke with came away impressed with the raw performance.  However, Exalogic offers a lot more than just raw performance.  I had the pleasure of working with Ram Sivaram during one of the Exalogic training sessions in Santa Clara.  In this video diary, he shows the Exalogic machine arrive on the shipping dock, get unpacked, wired up, powered on, configured, and installed with a WebLogic Server cluster in just about 10 hours.  I’ve worked with customers in the past that have taken several weeks or longer to get an environment ready after the hardware arrives.  This typically involves many different specialized teams in their organization.  Mohamad Afshar just wrote a great explanation of the benefit of Engineered Systems and contrasting that to the status quo.  Being able to streamline deployment of middleware capacity will have a lot of value for customers shortening time to deployment.  Thanks for the video Ram, you’ve set a high bar, we’ll see if anyone can top your time!

• De-index URL parameters by value

  - by Doug Firr

  Upon reading over this question is lengthy so allow me to provide a one sentence summary: I need to get Google to de-index URLs that have parameters with certain values appended I have a website example.com with language translations. There used to be many translations but I deleted them all so that only English (Default) and French options remain. When one selects a language option a parameter is aded to the URL. For example, the home page: https://example.com (default) https://example.com/main?l=fr_FR (French) I added a robots.txt to stop Google from crawling any of the language translations: # robots.txt generated at http://www.mcanerin.com User-agent: * Disallow: Disallow: /cgi-bin/ Disallow: /*?l= So any pages containing "?l=" should not be crawled. I checked in GWT using the robots testing tool. It works. But under html improvements the previously crawled language translation URLs remain indexed. The internet says to add a 404 to the header of the removed URLs so the Googles knows to de-index it. I checked to see what my CMS would throw up if I visited one of the URLs that should no longer exist. This URL was listed in GWT under duplicate title tags (One of the reasons I want to scrub up my URLS) https://example.com/reports/view/884?l=vi_VN&l=hy_AM This URL should not exist - I removed the language translations. The page loads when it should not! I played around. I typed example.com?whatever123 It seems that parameters always load as long as everything before the question mark is a real URL. So if Google has indexed all these URLS with parameters how do I remove them? I cannot check if a 404 is being generated because the page always loads because it's a parameter that needs to be de-indexed.

As an industry, we’ve spent many years analyzing all the data that’s been collected. Yes, that data has been invaluable in helping us make better decisions like where to open new stores, how to assort those stores, and how to price our products. But the recent advances in technology are now making it possible to analyze and deliver that data very quickly… fast enough to impact a potential sale in near real-time. Let me give you two examples. Salesmen in car dealerships get pretty good at sizing people up. When a potential customer walks in the door, it doesn’t take long for the salesman to figure out the revenue at stake. Is this person a real buyer, or just looking for a fun test drive? Will this person buy today or three months from now? Will this person opt for the expensive packages, or go bare bones? While the salesman certainly asks some leading questions, much of information is discerned through body language. But body language doesn’t translate very well over the web. Eloqua, which was acquired by Oracle earlier this year, reads internet body language. By tracking the behavior of the people visiting your web site, Eloqua categorizes visitors based on their propensity to buy. While Eloqua’s roots have been in B2B, we’ve been looking at leveraging the technology with ATG to target B2C. Knowing what sites were previously visited, how often the customer has been to your site recently, and how long they’ve spent searching can help understand where the customer is in their purchase journey. And knowing that bit of information may be enough to help close the deal with a real-time offer, follow-up email, or online customer service pop-up. This isn’t so different from the days gone by when the clerk behind the counter of the corner store noticed you were lingering in a particular aisle, so he walked over to help you compare two products and close the sale. You appreciated the personalized service, and he knew the value of the long-term relationship. Move that same concept into the digital world and you have Oracle’s CX Suite, a cloud-based offering of end-to-end customer experience tools, assembled primarily from acquisitions. Those tools are Oracle Marketing (Eloqua), Oracle Commerce (ATG, Endeca), Oracle Sales (Oracle CRM On Demand), Oracle Service (RightNow), Oracle Social (Collective Intellect, Vitrue, Involver), and Oracle Content (Fatwire). We are providing the glue that binds the CIO and CMO together to unleash synergies that drive the top-line higher, and by virtue of the cloud-approach, keep costs at bay. My second example of real-time marketing takes place in the store but leverages the concepts of Web marketing. In 1962 the decline of personalized service in retail began. Anyone know the significance of that year? That’s when Target, K-Mart, and Walmart each opened their first stores, and over the succeeding years the industry chose scale over personal service. No longer were you known as “Jane with the snotty kid so make sure we check her out fast,” but you suddenly became “time-starved female age 20-30 with kids.” I’m not saying that was a bad thing – it was the right thing for our industry at the time, and it enabled a huge amount of growth, cheaper prices, and more variety of products. But scale alone is no longer good enough. Today’s sophisticated consumer demands scale, experience, and personal attention. To some extent we’ve delivered that on websites via the magic of cookies, your willingness to log in, and sophisticated data analytics. What store manager wouldn’t love a report detailing all the visitors to his store, where they came from, and which products that examined? People trackers are getting more sophisticated, incorporating infrared, video analytics, and even face recognition. (Next time you walk in front on a mannequin, don’t be surprised if it’s looking back.) But the ultimate marketing conduit is the mobile phone. Since each mobile phone emits a unique number on WiFi networks, it becomes the cookie of the physical world. Assuming congress keeps privacy safeguards reasonable, we’ll have a win-win situation for both retailers and consumers. Retailers get to know more about the consumer’s purchase journey, and consumers get higher levels of service with the retailer. When I call my bank, a couple things happen before the call is connected. A reverse look-up on my phone number identifies me so my accounts can be retrieved from Siebel CRM. Then the system anticipates why I’m calling based on recent transactions. In this example, it sees that I was just charged a foreign currency fee, so it assumes that’s the reason I’m calling. It puts all the relevant information on the customer service rep’s screen as it connects the call. When I complain about the fee, the rep immediately sees I’m a great customer and I travel lots, so she suggests switching me to their traveler’s card that doesn’t have foreign transaction fees. That technology is powered by a product called Oracle Real-Time Decisions, a rules engine built to execute very quickly, basically in the time it takes the phone to ring once. So let’s combine the power of that product with our new-found mobile cookie and provide contextual customer interactions in real-time. Our first opportunity comes when a customer crosses a pre-defined geo-fence, typically a boundary around the store. Context is the key to our interaction: that’s the customer (known or anonymous), the time of day and day of week, and location. Thomas near the downtown store on a Wednesday at noon means he’s heading to lunch. If he were near the mall location on a Saturday morning, that’s a completely different context. But on his way to lunch, we’ll let Thomas know that we’ve got a new shipment of ASICS running shoes on display with a simple text message. We used the context to look-up Thomas’ past purchases and understood he was an avid runner. We used the fact that this was lunchtime to select the type of message, in this case an informational message instead of an offer. Thomas enters the store, phone in hand, and walks to the shoe department. He scans one of the new ASICS shoes using the convenient QR Codes we provided on the shelf-tags, but then he starts scanning low-end Nikes. Each scan is another opportunity to both learn from Thomas and potentially interact via another message. Since he historically buys low-end Nikes and keeps scanning them, he’s likely falling back into his old ways. Our marketing rules are currently set to move loyal customer to higher margin products. We could have set the dials to increase visit frequency, move overstocked items, increase basket size, or many other settings, but today we are trying to move Thomas to higher-margin products. We send Thomas another text message, this time it’s a personalized offer for 10% off ASICS good for 24 hours. Offering him a discount on Nikes would be throwing margin away since he buys those anyway. We are using our marketing dollars to change behavior that increases the long-term value of Thomas. He decides to buy the ASICS and scans the discount code on his phone at checkout. Checkout is yet another opportunity to interact with Thomas, so the transaction is sent back to Oracle RTD for evaluation. Since Thomas didn’t buy anything with the shoes, we’ll print a bounce-back coupon on the receipt offering 30% off ASICS socks if he returns within seven days. We have successfully started moving Thomas from low-margin to high-margin products. In both of these marketing scenarios, we are able to leverage data in near real-time to decide how best to interact with the customer and lead to an increase in the lifetime value of the customer. The key here is acting at the moment the customer shows interest using the context of the situation. We aren’t pushing random products at haphazard times. We are tailoring the marketing to be very specific to this customer, and it’s the technology that allows this to happen in near real-time. Conclusion As we enable more right-time integrations and interactions, retailers will begin to offer increased service to their customers. Localized and personalized service at scale will drive loyalty and lead to meaningful revenue growth for the retailers that execute well. Our industry needs to support Commerce Anywhere…and commerce anytime as well.

• Installing 12.04 within 11.04

  - by user288752

  I recently installed 11.04 from an installation disk (overwriting Windows in the process). I know 11.04 is no longer supported but I had no problems subsequently upgrading it to 12.04 (via 11.10) a couple of months ago on another device. This time though, things are different. I can't upgrade through update manager because Ubuntu then tells me I have no internet connection, which is (obviously incorrect). I have tried to circumvent the problem by downloading the 12:04 iso from ubuntu.com directly but now I'm troubled by something else. The download is succesfull but after mounting the iso I can't interact with it. When I try to access the Wubi it gives me the following message: Archive: /home/lars/.cache/.fr-7g75Fe/wubi.exe [/home/lars/.cache/.fr-7g75Fe/wubi.exe] End-of-central-directory signature not found. Either this file is not a zipfile, or it constitutes one disk of a multi-part archive. In the latter case the central directory and zipfile comment will be found on the last disk(s) of this archive. zipinfo: cannot find zipfile directory in one of /home/lars/.cache/.fr-7g75Fe/wubi.exe or /home/lars/.cache/.fr-7g75Fe/wubi.exe.zip, and cannot find /home/lars/.cache/.fr-7g75Fe/wubi.exe.ZIP, period. What am I doing wrong here?

• Manage SQL Server Connectivity through Windows Azure Virtual Machines Remote PowerShell

  - by SQLOS Team

  Manage SQL Server Connectivity through Windows Azure Virtual Machines Remote PowerShell Blog This blog post comes from Khalid Mouss, Senior Program Manager in Microsoft SQL Server. Overview The goal of this blog is to demonstrate how we can automate through PowerShell connecting multiple SQL Server deployments in Windows Azure Virtual Machines. We would configure TCP port that we would open (and close) though Windows firewall from a remote PowerShell session to the Virtual Machine (VM). This will demonstrate how to take the advantage of the remote PowerShell support in Windows Azure Virtual Machines to automate the steps required to connect SQL Server in the same cloud service and in different cloud services.  Scenario 1: VMs connected through the same Cloud Service 2 Virtual machines configured in the same cloud service. Both VMs running different SQL Server instances on them. Both VMs configured with remote PowerShell turned on to be able to run PS and other commands directly into them remotely in order to re-configure them to allow incoming SQL connections from a remote VM or on premise machine(s). Note: RDP (Remote Desktop Protocol) is kept configured in both VMs by default to be able to remote connect to them and check the connections to SQL instances for demo purposes only; but not actually required. Step 1 – Provision VMs and Configure Ports   Provision VM1; named DemoVM1 as follows (see examples screenshots below if using the portal):   Provision VM2 (DemoVM2) with PowerShell Remoting enabled and connected to DemoVM1 above (see examples screenshots below if using the portal): After provisioning of the 2 VMs above, here is the default port configurations for example: Step2 – Verify / Confirm the TCP port used by the database Engine By the default, the port will be configured to be 1433 – this can be changed to a different port number if desired.   1. RDP to each of the VMs created below – this will also ensure the VMs complete SysPrep(ing) and complete configuration 2. Go to SQL Server Configuration Manager -> SQL Server Network Configuration -> Protocols for <SQL instance> -> TCP/IP - > IP Addresses   3. Confirm the port number used by SQL Server Engine; in this case 1433 4. Update from Windows Authentication to Mixed mode   5.       Restart SQL Server service for the change to take effect 6.       Repeat steps 3., 4., and 5. For the second VM: DemoVM2 Step 3 – Remote Powershell to DemoVM1 Enter-PSSession -ComputerName condemo.cloudapp.net -Port 61503 -Credential <username> -UseSSL -SessionOption (New-PSSessionOption -SkipCACheck -SkipCNCheck) Your will then be prompted to enter the password. Step 4 – Open 1433 port in the Windows firewall netsh advfirewall firewall add rule name="DemoVM1Port" dir=in localport=1433 protocol=TCP action=allow Output: netsh advfirewall firewall show rule name=DemoVM1Port Rule Name:                            DemoVM1Port ---------------------------------------------------------------------- Enabled:                              Yes Direction:                            In Profiles:                             Domain,Private,Public Grouping:                             LocalIP:                              Any RemoteIP:                             Any Protocol:                             TCP LocalPort:                            1433 RemotePort:                           Any Edge traversal:                       No Action:                               Allow Ok. Step 5 – Now connect from DemoVM2 to DB instance in DemoVM1 Step 6 – Close port 1433 in the Windows firewall netsh advfirewall firewall delete rule name=DemoVM1Port Output: Deleted 1 rule(s). Ok. netsh advfirewall firewall show  rule name=DemoVM1Port No rules match the specified criteria.   Step 7 – Try to connect from DemoVM2 to DB Instance in DemoVM1  Because port 1433 has been closed (in step 6) in the Windows Firewall in VM1 machine, we can longer connect from VM3 remotely to VM1. Scenario 2: VMs provisioned in different Cloud Services 2 Virtual machines configured in different cloud services. Both VMs running different SQL Server instances on them. Both VMs configured with remote PowerShell turned on to be able to run PS and other commands directly into them remotely in order to re-configure them to allow incoming SQL connections from a remote VM or on on-premise machine(s). Note: RDP (Remote Desktop Protocol) is kept configured in both VMs by default to be able to remote connect to them and check the connections to SQL instances for demo purposes only; but not actually needed. Step 1 – Provision new VM3 Provision VM3; named DemoVM3 as follows (see examples screenshots below if using the portal): After provisioning is complete, here is the default port configurations: Step 2 – Add public port to VM1 connect to from VM3’s DB instance Since VM3 and VM1 are not connected in the same cloud service, we will need to specify the full DNS address while connecting between the machines which includes the public port. We shall add a public port 57000 in this case that is linked to private port 1433 which will be used later to connect to the DB instance. Step 3 – Remote Powershell to DemoVM1 Enter-PSSession -ComputerName condemo.cloudapp.net -Port 61503 -Credential <UserName> -UseSSL -SessionOption (New-PSSessionOption -SkipCACheck -SkipCNCheck) You will then be prompted to enter the password.   Step 4 – Open 1433 port in the Windows firewall netsh advfirewall firewall add rule name="DemoVM1Port" dir=in localport=1433 protocol=TCP action=allow Output: Ok. netsh advfirewall firewall show rule name=DemoVM1Port Rule Name:                            DemoVM1Port ---------------------------------------------------------------------- Enabled:                              Yes Direction:                            In Profiles:                             Domain,Private,Public Grouping:                             LocalIP:                              Any RemoteIP:                             Any Protocol:                             TCP LocalPort:                            1433 RemotePort:                           Any Edge traversal:                       No Action:                               Allow Ok.   Step 5 – Now connect from DemoVM3 to DB instance in DemoVM1 RDP into VM3, launch SSM and Connect to VM1’s DB instance as follows. You must specify the full server name using the DNS address and public port number configured above. Step 6 – Close port 1433 in the Windows firewall netsh advfirewall firewall delete rule name=DemoVM1Port   Output: Deleted 1 rule(s). Ok. netsh advfirewall firewall show  rule name=DemoVM1Port No rules match the specified criteria.  Step 7 – Try to connect from DemoVM2 to DB Instance in DemoVM1  Because port 1433 has been closed (in step 6) in the Windows Firewall in VM1 machine, we can no longer connect from VM3 remotely to VM1. Conclusion Through the new support for remote PowerShell in Windows Azure Virtual Machines, one can script and automate many Virtual Machine and SQL management tasks. In this blog, we have demonstrated, how to start a remote PowerShell session, re-configure Virtual Machine firewall to allow (or disallow) SQL Server connections.
