• Prevent your Silverlight XAP file from caching in your browser.

  - by mbcrump

  If you work with Silverlight daily then you have run into this problem. Your XAP file has been cached in your browser and you have to empty your browser cache to resolve it. If your using Google Chrome then you typically do the following: Go to Options –> Clear Browsing History –> Empty the Cache and finally click Clear Browsing data. As you can see, this is a lot of unnecessary steps. It is even worse when you have a customer that says, “I can’t see the new features you just implemented!” and you realize it’s a cached xap problem.  I have been struggling with a way to prevent my XAP file from caching inside of a browser for a while now and decided to implement the following solution. If the Visual Studio Debugger is attached then add a unique query string to the source param to force the XAP file to be refreshed. If the Visual Studio Debugger is not attached then add the source param as Visual Studio generates it. This is also in case I forget to remove the above code in my production environment. I want the ASP.NET code to be inline with my .ASPX page. (I do not want a separate code behind .cs page or .vb page attached to the .aspx page.) Below is an example of the hosting code generated when you create a new Silverlight project. As a quick refresher, the hard coded param name = “source” specifies the location of your XAP file.  <form id="form1" runat="server" style="height:100%"> <div id="silverlightControlHost"> <object data="data:application/x-silverlight-2," type="application/x-silverlight-2" width="100%" height="100%"> <param name="source" value="ClientBin/SilverlightApplication2.xap"/> <param name="onError" value="onSilverlightError" /> <param name="background" value="white" /> <param name="minRuntimeVersion" value="4.0.50826.0" /> <param name="autoUpgrade" value="true" /> <a href="http://go.microsoft.com/fwlink/?LinkID=149156&v=4.0.50826.0" style="text-decoration:none"> <img src="http://go.microsoft.com/fwlink/?LinkId=161376" alt="Get Microsoft Silverlight" style="border-style:none"/> </a> </object><iframe id="_sl_historyFrame" style="visibility:hidden;height:0px;width:0px;border:0px"></iframe></div> </form> We are going to use a little bit of inline ASP.NET to generate the param name = source dynamically to prevent the XAP file from caching. Lets look at the completed solution: <form id="form1" runat="server" style="height:100%"> <div id="silverlightControlHost"> <object data="data:application/x-silverlight-2," type="application/x-silverlight-2" width="100%" height="100%"> <% string strSourceFile = @"ClientBin/SilverlightApplication2.xap"; string param; if (System.Diagnostics.Debugger.IsAttached) //Debugger Attached - Refresh the XAP file. param = "<param name=\"source\" value=\"" + strSourceFile + "?" + DateTime.Now.Ticks + "\" />"; else { //Production Mode param = "<param name=\"source\" value=\"" + strSourceFile + "\" />"; } Response.Write(param); %> <param name="onError" value="onSilverlightError" /> <param name="background" value="white" /> <param name="minRuntimeVersion" value="4.0.50826.0" /> <param name="autoUpgrade" value="true" /> <a href="http://go.microsoft.com/fwlink/?LinkID=149156&v=4.0.50826.0" style="text-decoration:none"> <img src="http://go.microsoft.com/fwlink/?LinkId=161376" alt="Get Microsoft Silverlight" style="border-style:none"/> </a> </object><iframe id="_sl_historyFrame" style="visibility:hidden;height:0px;width:0px;border:0px"></iframe></div> </form> We add the location to our XAP file to strSourceFile and if the debugger is attached then it will append DateTime.Now.Ticks to the XAP file source and force the browser to download the .XAP. If you view the page source of your Silverlight Application then you can verify it worked properly by looking at the param name = “source” tag as shown below. <param name="source" value="ClientBin/SilverlightApplication2.xap?634299001187160148" /> If the debugger is not attached then it will use the standard source tag as shown below. <param name="source" value="ClientBin/SilverlightApplication2.xap"/> At this point you may be asking, How do I prevent my XAP file from being cached on my production app? Well, you have two easy options: 1) I really don’t recommend this approach but you can force the XAP to be refreshed everytime with the following code snippet.  <param name="source" value="ClientBin/SilverlightApplication2.xap?<%=Guid.NewGuid().ToString() %>"/> NOTE: You could also substitute the “Guid.NewGuid().ToString() for anything that create a random field. (I used DateTime.Now.Ticks earlier). 2) Another solution that I like even better involves checking the XAP Creation Date and appending it to the param name = source. This method was described by Lars Holm Jenson. <% string strSourceFile = @"ClientBin/SilverlightApplication2.xap"; string param; if (System.Diagnostics.Debugger.IsAttached) param = "<param name=\"source\" value=\"" + strSourceFile + "\" />"; else { string xappath = HttpContext.Current.Server.MapPath(@"") + @"\" + strSourceFile; DateTime xapCreationDate = System.IO.File.GetLastWriteTime(xappath); param = "<param name=\"source\" value=\"" + strSourceFile + "?ignore=" + xapCreationDate.ToString() + "\" />"; } Response.Write(param); %> As you can see, this problem has been solved. It will work with all web browsers and stubborn proxy servers that are caching your .XAP. If you enjoyed this article then check out my blog for others like this.

• Fraud Detection with the SQL Server Suite Part 2

  - by Dejan Sarka

  This is the second part of the fraud detection whitepaper. You can find the first part in my previous blog post about this topic. My Approach to Data Mining Projects It is impossible to evaluate the time and money needed for a complete fraud detection infrastructure in advance. Personally, I do not know the customer’s data in advance. I don’t know whether there is already an existing infrastructure, like a data warehouse, in place, or whether we would need to build one from scratch. Therefore, I always suggest to start with a proof-of-concept (POC) project. A POC takes something between 5 and 10 working days, and involves personnel from the customer’s site – either employees or outsourced consultants. The team should include a subject matter expert (SME) and at least one information technology (IT) expert. The SME must be familiar with both the domain in question as well as the meaning of data at hand, while the IT expert should be familiar with the structure of data, how to access it, and have some programming (preferably Transact-SQL) knowledge. With more than one IT expert the most time consuming work, namely data preparation and overview, can be completed sooner. I assume that the relevant data is already extracted and available at the very beginning of the POC project. If a customer wants to have their people involved in the project directly and requests the transfer of knowledge, the project begins with training. I strongly advise this approach as it offers the establishment of a common background for all people involved, the understanding of how the algorithms work and the understanding of how the results should be interpreted, a way of becoming familiar with the SQL Server suite, and more. Once the data has been extracted, the customer’s SME (i.e. the analyst), and the IT expert assigned to the project will learn how to prepare the data in an efficient manner. Together with me, knowledge and expertise allow us to focus immediately on the most interesting attributes and identify any additional, calculated, ones soon after. By employing our programming knowledge, we can, for example, prepare tens of derived variables, detect outliers, identify the relationships between pairs of input variables, and more, in only two or three days, depending on the quantity and the quality of input data. I favor the customer’s decision of assigning additional personnel to the project. For example, I actually prefer to work with two teams simultaneously. I demonstrate and explain the subject matter by applying techniques directly on the data managed by each team, and then both teams continue to work on the data overview and data preparation under our supervision. I explain to the teams what kind of results we expect, the reasons why they are needed, and how to achieve them. Afterwards we review and explain the results, and continue with new instructions, until we resolve all known problems. Simultaneously with the data preparation the data overview is performed. The logic behind this task is the same – again I show to the teams involved the expected results, how to achieve them and what they mean. This is also done in multiple cycles as is the case with data preparation, because, quite frankly, both tasks are completely interleaved. A specific objective of the data overview is of principal importance – it is represented by a simple star schema and a simple OLAP cube that will first of all simplify data discovery and interpretation of the results, and will also prove useful in the following tasks. The presence of the customer’s SME is the key to resolving possible issues with the actual meaning of the data. We can always replace the IT part of the team with another database developer; however, we cannot conduct this kind of a project without the customer’s SME. After the data preparation and when the data overview is available, we begin the scientific part of the project. I assist the team in developing a variety of models, and in interpreting the results. The results are presented graphically, in an intuitive way. While it is possible to interpret the results on the fly, a much more appropriate alternative is possible if the initial training was also performed, because it allows the customer’s personnel to interpret the results by themselves, with only some guidance from me. The models are evaluated immediately by using several different techniques. One of the techniques includes evaluation over time, where we use an OLAP cube. After evaluating the models, we select the most appropriate model to be deployed for a production test; this allows the team to understand the deployment process. There are many possibilities of deploying data mining models into production; at the POC stage, we select the one that can be completed quickly. Typically, this means that we add the mining model as an additional dimension to an existing DW or OLAP cube, or to the OLAP cube developed during the data overview phase. Finally, we spend some time presenting the results of the POC project to the stakeholders and managers. Even from a POC, the customer will receive lots of benefits, all at the sole risk of spending money and time for a single 5 to 10 day project: The customer learns the basic patterns of frauds and fraud detection The customer learns how to do the entire cycle with their own people, only relying on me for the most complex problems The customer’s analysts learn how to perform much more in-depth analyses than they ever thought possible The customer’s IT experts learn how to perform data extraction and preparation much more efficiently than they did before All of the attendees of this training learn how to use their own creativity to implement further improvements of the process and procedures, even after the solution has been deployed to production The POC output for a smaller company or for a subsidiary of a larger company can actually be considered a finished, production-ready solution It is possible to utilize the results of the POC project at subsidiary level, as a finished POC project for the entire enterprise Typically, the project results in several important “side effects” Improved data quality Improved employee job satisfaction, as they are able to proactively contribute to the central knowledge about fraud patterns in the organization Because eventually more minds get to be involved in the enterprise, the company should expect more and better fraud detection patterns After the POC project is completed as described above, the actual project would not need months of engagement from my side. This is possible due to our preference to transfer the knowledge onto the customer’s employees: typically, the customer will use the results of the POC project for some time, and only engage me again to complete the project, or to ask for additional expertise if the complexity of the problem increases significantly. I usually expect to perform the following tasks: Establish the final infrastructure to measure the efficiency of the deployed models Deploy the models in additional scenarios Through reports By including Data Mining Extensions (DMX) queries in OLTP applications to support real-time early warnings Include data mining models as dimensions in OLAP cubes, if this was not done already during the POC project Create smart ETL applications that divert suspicious data for immediate or later inspection I would also offer to investigate how the outcome could be transferred automatically to the central system; for instance, if the POC project was performed in a subsidiary whereas a central system is available as well Of course, for the actual project, I would repeat the data and model preparation as needed It is virtually impossible to tell in advance how much time the deployment would take, before we decide together with customer what exactly the deployment process should cover. Without considering the deployment part, and with the POC project conducted as suggested above (including the transfer of knowledge), the actual project should still only take additional 5 to 10 days. The approximate timeline for the POC project is, as follows: 1-2 days of training 2-3 days for data preparation and data overview 2 days for creating and evaluating the models 1 day for initial preparation of the continuous learning infrastructure 1 day for presentation of the results and discussion of further actions Quite frequently I receive the following question: are we going to find the best possible model during the POC project, or during the actual project? My answer is always quite simple: I do not know. Maybe, if we would spend just one hour more for data preparation, or create just one more model, we could get better patterns and predictions. However, we simply must stop somewhere, and the best possible way to do this, according to my experience, is to restrict the time spent on the project in advance, after an agreement with the customer. You must also never forget that, because we build the complete learning infrastructure and transfer the knowledge, the customer will be capable of doing further investigations independently and improve the models and predictions over time without the need for a constant engagement with me.

Reposted (Borrowed) from his posting of May 24, 2012 Dear [insert business name], what’s your promise? - Brian Solis You say you want to get closer to customers, but your actions are different than your words. You say you want to “surprise and delight” customers, but your product development teams are too busy building against a roadmap without consideration of the 5th P of marketing…people. Your employees are your number one asset, however the infrastructure of the organization has turned once optimistic and ambitious intrapreneurs into complacent cogs or worse, your greatest detractors. You question the adoption of disruptive technology by your internal champions yet you’ve not tried to find the value for yourself. You’re a change agent and you truly wish to bring about change, but you’ve not invested time or resources to answer “why” in your endeavors to become a connected or social business. If we are to truly change, we must find purpose. We must uncover the essence of our business and the value it delivers to traditional and connected consumers. We must rethink the spirit of today’s embrace and clearly articulate how transformation is going to improve customer and employee experiences and relationships now and over time. Without doing so, any attempts at evolution will be thwarted by reality. In an era of Digital Darwinism, no business is too big to fail or too small to succeed. These are undisciplined times which require alternative approaches to recognize and pursue new opportunities. But everything begins with acknowledging the 360 view of the world that you see today is actually a filtered view of managed and efficient convenience. Today, many organizations that were once inspired by innovation and engagement have fallen into a process of marketing, operationalizing, managing, and optimizing. That might have worked for the better part of the last century, but for the next 10 years and beyond, new vision, leadership and supporting business models will be written to move businesses from rigid frameworks to adaptive and agile entities. I believe that today’s executives will undergo a great test; a test of character, vision, intention, and universal leadership. It starts with a simple, but essential question…what is your promise? Notice, I didn’t ask about your brand promise. Nor did I ask for you to cite your mission and vision statements. This is much more than value propositions or manufactured marketing language designed to hook audiences and stakeholders. I asked for your promise to me as your consumer, stakeholder, and partner. This isn’t about B2B or B2C, but instead, people to people, person to person. It is this promise that will breathe new life into an organization that on the outside, could be misdiagnosed as catatonic by those who are disrupting your markets. A promise, for example, is meant to inspire. It creates alignment. It serves as the foundation for your vision, mission, and all business strategies and it must come from the top to mean anything. For without it, we cannot genuinely voice what it is we stand for or stand behind. Think for a moment about the definition of community. It’s easy to confuse a workplace or a market where everyone simply shares common characteristics. However, a community in this day and age is much more than belonging to something, it’s about doing something together that makes belonging matter The next few years will force a divide where companies are separated by intention as measured by actions and words. But, becoming a social business is not enough. Becoming more authentic and transparent doesn’t serve as a mantra for a renaissance. A promise is the ink that inscribes the spirit of the relationship between you and me. A promise serves as the words that influence change from within and change beyond the halls of our business. It is the foundation for a renewed embrace, one that must then find its way to every aspect of the organization. It’s the difference between a social business and an adaptive business. While an adaptive business can also be social, it is the culture of the organization that strives to not just use technology to extend current philosophies or processes into new domains, but instead give rise to a new culture where striving for relevance is among its goals. The tools and networks simply become enablers of a greater mission You are reading this because you believe in something more than what you’re doing today. While you fight for change within your organization, remember to aim for a higher purpose. Organizations that strive for innovation, imagination, and relevance will outperform those that do not. Part of your job is to lead a missionary push that unites the groundswell with a top down cascade. Change will only happen because you and other internal champions see what others can’t and will do what other won’t. It takes resolve. It takes the ability to translate new opportunities into business value. And, it takes courage. “This is a very noisy world, so we have to be very clear what we want them to know about us”-Steve Jobs ----------------------------------------------------------------- So -- where do you begin to evaluate the kind of experience you are delivering for your customers, partners, and employees?  Take a look at this White Paper: Creating a Successful and Meaningful Customer Experience on the Web and then have a cup of coffee while you listen to the sage advice of Guy Kawasaki in a short video below.   An interview with Guy Kawasaki on Maximizing Social Media Channels

• Tracing Silex from PHP to the OS with DTrace

  - by cj

  In this blog post I show the full stack tracing of Brendan Gregg's php_syscolors.d script in the DTrace Toolkit. The Toolkit contains a dozen very useful PHP DTrace scripts and many more scripts for other languages and the OS. For this example, I'll trace the PHP micro framework Silex, which was the topic of the second of two talks by Dustin Whittle at a recent SF PHP Meetup. His slides are at Silex: From Micro to Full Stack. Installing DTrace and PHP The php_syscolors.d script uses some static PHP probes and some kernel probes. For Oracle Linux I discussed installing DTrace and PHP in DTrace PHP Using Oracle Linux 'playground' Pre-Built Packages. On other platforms with DTrace support, follow your standard procedures to enable DTrace and load the correct providers. The sdt and systrace providers are required in addition to fasttrap. On Oracle Linux, I loaded the DTrace modules like: # modprobe fasttrap # modprobe sdt # modprobe systrace # chmod 666 /dev/dtrace/helper Installing the DTrace Toolkit I download DTraceToolkit-0.99.tar.gz and extracted it: $ tar -zxf DTraceToolkit-0.99.tar.gz The PHP scripts are in the Php directory and examples in the Examples directory. Installing Silex I downloaded the "fat" Silex .tgz file from the download page and extracted it: $ tar -zxf silex_fat.tgz I changed the demonstration silex/web/index.php so I could use the PHP development web server: <?php // web/index.php $filename = __DIR__.preg_replace('#(\?.*)$#', '', $_SERVER['REQUEST_URI']); if (php_sapi_name() === 'cli-server' && is_file($filename)) { return false; } require_once __DIR__.'/../vendor/autoload.php'; $app = new Silex\Application(); //$app['debug'] = true; $app->get('/hello', function() { return 'Hello!'; }); $app->run(); ?> Running DTrace The php_syscolors.d script uses the -Z option to dtrace, so it can be started before PHP, i.e. when there are zero of the requested probes available to be traced. I ran DTrace like: # cd DTraceToolkit-0.99/Php # ./php_syscolors.d Next, I started the PHP developer web server in a second terminal: $ cd silex $ php -S localhost:8080 -t web web/index.php At this point, the web server is idle, waiting for requests. DTrace is idle, waiting for the probes in php_syscolors.d to be fired, at which time the action associated with each probe will run. I then loaded the demonstration page in a browser: http://localhost:8080/hello When the request was fulfilled and the simple output of "Hello" was displayed, I ^C'd php and dtrace in their terminals to stop them. DTrace output over a thousand lines long had been generated. Here is one snippet from when run() was invoked: C PID/TID DELTA(us) FILE:LINE TYPE -- NAME ... 1 4765/4765 21 Application.php:487 func -> run 1 4765/4765 29 ClassLoader.php:182 func -> loadClass 1 4765/4765 17 ClassLoader.php:198 func -> findFile 1 4765/4765 31 ":- syscall -> access 1 4765/4765 26 ":- syscall <- access 1 4765/4765 16 ClassLoader.php:198 func <- findFile 1 4765/4765 25 ":- syscall -> newlstat 1 4765/4765 15 ":- syscall <- newlstat 1 4765/4765 13 ":- syscall -> newlstat 1 4765/4765 13 ":- syscall <- newlstat 1 4765/4765 22 ":- syscall -> newlstat 1 4765/4765 14 ":- syscall <- newlstat 1 4765/4765 15 ":- syscall -> newlstat 1 4765/4765 60 ":- syscall <- newlstat 1 4765/4765 13 ":- syscall -> newlstat 1 4765/4765 13 ":- syscall <- newlstat 1 4765/4765 20 ":- syscall -> open 1 4765/4765 16 ":- syscall <- open 1 4765/4765 26 ":- syscall -> newfstat 1 4765/4765 12 ":- syscall <- newfstat 1 4765/4765 17 ":- syscall -> newfstat 1 4765/4765 12 ":- syscall <- newfstat 1 4765/4765 12 ":- syscall -> newfstat 1 4765/4765 12 ":- syscall <- newfstat 1 4765/4765 20 ":- syscall -> mmap 1 4765/4765 14 ":- syscall <- mmap 1 4765/4765 3201 ":- syscall -> mmap 1 4765/4765 27 ":- syscall <- mmap 1 4765/4765 1233 ":- syscall -> munmap 1 4765/4765 53 ":- syscall <- munmap 1 4765/4765 15 ":- syscall -> close 1 4765/4765 13 ":- syscall <- close 1 4765/4765 34 Request.php:32 func -> main 1 4765/4765 22 Request.php:32 func <- main 1 4765/4765 31 ClassLoader.php:182 func <- loadClass 1 4765/4765 33 Request.php:249 func -> createFromGlobals 1 4765/4765 29 Request.php:198 func -> __construct 1 4765/4765 24 Request.php:218 func -> initialize 1 4765/4765 26 ClassLoader.php:182 func -> loadClass 1 4765/4765 89 ClassLoader.php:198 func -> findFile 1 4765/4765 43 ":- syscall -> access ... The output shows PHP functions being called and returning (and where they are located) and which system calls the PHP functions in turn invoked. The time each line took from the previous one is displayed in the third column. The first column is the CPU number. In this example, the process was always on CPU 1 so the output is naturally ordered without requiring post-processing, or the D script requiring to be modified to display a time stamp. On a terminal, the output of php_syscolors.d is color-coded according to whether each function is a PHP or system one, hence the file name. Summary With one tool, I was able to trace the interaction of a user application with the operating system. I was able to do this to an application running "live" in a web context. The DTrace Toolkit provides a very handy repository of DTrace information. Even though the PHP scripts were created in the time frame of the original PHP DTrace PECL extension, which only had PHP function entry and return probes, the scripts provide core examples for custom investigation and resolution scripts. You can easily adapt the ideas and and create scripts using the other PHP static probes, which are listed in the PHP Manual. Because DTrace is "always on", you can take advantage of it to resolve development questions or fix production situations.

• Communities - The importance of exchange and discussion

  Communication with your environment is an essential part of everyone's life. And it doesn't matter whether you are actually living in a rural area in the middle of nowhere, within the pulsating heart of a big city, or in my case on a wonderful island in the Indian Ocean. The ability to exchange your thoughts, your experience and your worries with another person helps you to get different points of view and new ideas on how to resolve an issue you might be confronted with. Benefits of community work What happens to be common sense in your daily life, also applies to your work environment. Working in IT, or ICT as it is called in Mauritius, requires a lot of reading and learning. Not only during your lectures at the university but with your colleagues in a project assignment and hopefully with 'unknown' pals in the universe of online communities. At least I can say that I learned quite a lot from other developers code, their responses in various forums, their numerous blog articles, and while attending local user group meetings. When I started to work as a professional software developer (or engineer some may say) years ago I immediately checked the existence of communities on the programming language, the database technology and other vital information on software development in general. Luckily, it wasn't too difficult to find. My employer had a subscription of the monthly magazines and newsletters of a national organisation which also run the biggest forum in that area. Getting in touch with other developers and reading their common problems but also solutions was a huge benefit to my growth. Image courtesy of Michael Kappel (CC BY-NC 2.0) Active participation and regular contribution to this community gave me some nice advantages, too. Within three years I was listed as a conference speaker at the annual developer's conference and provided several sessions on different topics during consecutive years. Back in 2004, I took over the responsibility and management of the monthly meetings of a regional user group, and organised it for more than two years. Furthermore, I was invited to the newly-founded community program of Microsoft Germany (Community Leader/Insider Program - CLIP). My website on Active FoxPro Pages was nominated in the second batch of online communities. Due to my community work and providing advice to others, I had the honour to be awarded as Microsoft Most Valuable Professional (MVP) - Visual Developer for Visual FoxPro in the years 2006 and 2007. It was a great experience to meet with other like-minded people and I'm really grateful for that. Just in case, more details are listed in my Curriculum Vitae. But this all changed when I moved to Mauritius... Cyber island Mauritius? During the first months in Mauritius I was way too busy to think about community activities at all. First of all, there was the new company that had to be set up, the new staff had to be trained and of course the communication work-flows and so on with the project managers back in Germany had to be sorted out, too. Second, I had to get a grip of my private matters like getting the basics for my new household or exploring the neighbourhood, and last but not least I needed a break from the hectic and intensive work prior to my departure. As soon as the sea literally calmed down, I started to have conversations with my colleagues about communities and user groups. Sadly, it turned out that there were none, or at least no one was aware of any at that time. Oh oh, what did I do? Anyway, having this kind of background and very positive experience with off-line and on-line activities I decided for myself that some day I'm going to found a community in Mauritius for all kind of IT/ICT-related fields. The main focus might be on software development but not on a certain technology or methodology. It was clear to me that it should be an open infrastructure and anyone is welcome to join, to experience, to share and to contribute if they would like to. That was the idea at that time... Ok, fast-forward to recent events. At the end of October 2012 I was invited to an event called Open Days organised by Microsoft Indian Ocean Islands together with other local partners and resellers. There I got in touch with local Technical Evangelist Arnaud Meslier and we had a good conversation on communities during the breaks. Eventually, I left a good impression on him, as we are having chats on Facebook or Skype irregularly. Well, seeing that my personal and professional surroundings have been settled and running smooth, having that great exchange and contact with Microsoft IOI (again), and being really eager to re-animate my intentions from 2007, I recently founded a new community: Mauritius Software Craftsmanship Community - #MSCC It took me a while to settle down with the name but it was obvious that the community should not be attached to one single technology, like ie. .NET user group, Oracle developers, or Joomla friends (these are fictitious names). There are several other reasons why I came up with 'Craftsmanship' as the core topic of this community. The expression of 'engineering' didn't feel right with the fields covered. Software development in all kind of facets is a craft, and therefore demands a lot of practice but also guidance from more experienced developers. It also includes the process of designing, modelling and drafting the ideas. Has to deal with various types of tests and test methodologies, and of course should be focused on flexible and agile ways of acting. In order to meet and to excel a customer's request for a solution. Next, I was looking for an easy way to handle the organisation of events and meeting appointments. Using all kind of social media platforms like Google+, LinkedIn, Facebook, Xing, etc. I was never really confident about their features of event handling. More by chance I stumbled upon Meetup.com and in combination with the other entities (G+ Communities, FB Pages or in Groups) I am looking forward to advertise and manage all future activities here: Mauritius Software Craftsmanship Community This is a community for those who care and are proud of what they do. For those developers, regardless how experienced they are, who want to improve and master their craft. This is a community for those who believe that being average is just not good enough. I know, there are not many 'craftsmen' yet but it's a start... Let's see how it looks like by the end of the year. There are free smartphone apps for Android and iOS from Meetup.com that allow you to keep track of meetings and to stay informed on latest updates. And last but not least, there will be a Trello workspace to collect and share ideas and provide downloads of slides, etc. Sharing is caring! As mentioned, the #MSCC is present in various social media networks in order to cover as many people as possible here in Mauritius. Following is an overview of the current networks: Twitter - Latest updates and quickies Google+ - Community channel Facebook - Community Page LinkedIn - Community Group Trello - Collaboration workspace to share and develop ideas Hopefully, this covers the majority of computer-related people in Mauritius. Please spread the word about the #MSCC between your colleagues, your friends and other interested 'geeks'. Your future looks bright Running and participating in a user group or any kind of community usually provides quite a number of advantages for anyone. On the one side it is very joyful for me to organise appointments and get in touch with people that might be interested to present a little demo of their projects or their recent problems they had to tackle down, and on the other side there are lots of companies that have various support programs or sponsorships especially tailored for user groups. At the moment, I already have a couple of gimmicks that I would like to hand out in small contests or raffles during one of the upcoming meetings, and as said, companies provide all kind of goodies, books free of charge, or sometimes even licenses for communities. Meeting other software developers or IT guys also opens up your point of view on the local market and there might be interesting projects or job offers available, too. A community like the Mauritius Software Craftsmanship Community is great for freelancers, self-employed, students and of course employees. Meetings will be organised on a regular basis, and I'm open to all kind of suggestions from you. Please leave a comment here in blog or join the conversations in the above mentioned social networks. Let's get this community up and running, my fellow Mauritians!

• RIF PRD: Presentation syntax issues

  - by Charles Young

  Over Christmas I got to play a bit with the W3C RIF PRD and came across a few issues which I thought I would record for posterity. Specifically, I was working on a grammar for the presentation syntax using a GLR grammar parser tool (I was using the current CTP of ‘M’ (MGrammer) and Intellipad – I do so hope the MS guys don’t kill off M and Intellipad now they have dropped the other parts of SQL Server Modelling). I realise that the presentation syntax is non-normative and that any issues with it do not therefore compromise the standard. However, presentation syntax is useful in its own right, and it would be great to iron out any issues in a future revision of the standard. The main issues are actually not to do with the grammar at all, but rather with the ‘running example’ in the RIF PRD recommendation. I started with the code provided in Example 9.1. There are several discrepancies when compared with the EBNF rules documented in the standard. Broadly the problems can be categorised as follows: ·      Parenthesis mismatch – the wrong number of parentheses are used in various places. For example, in GoldRule, the RHS of the rule (the ‘Then’) is nested in the LHS (‘the If’). In NewCustomerAndWidgetRule, the RHS is orphaned from the LHS. Together with additional incorrect parenthesis, this leads to orphanage of UnknownStatusRule from the entire Document. ·      Invalid use of parenthesis in ‘Forall’ constructs. Parenthesis should not be used to enclose formulae. Removal of the invalid parenthesis gave me a feeling of inconsistency when comparing formulae in Forall to formulae in If. The use of parenthesis is not actually inconsistent in these two context, but in an If construct it ‘feels’ as if you are enclosing formulae in parenthesis in a LISP-like fashion. In reality, the parenthesis is simply being used to group subordinate syntax elements. The fact that an If construct can contain only a single formula as an immediate child adds to this feeling of inconsistency. ·      Invalid representation of compact URIs (CURIEs) in the context of Frame productions. In several places the URIs are not qualified with a namespace prefix (‘ex1:’). This conflicts with the definition of CURIEs in the RIF Datatypes and Built-Ins 1.0 document. Here are the productions: CURIE          ::= PNAME_LN                  | PNAME_NS PNAME_LN       ::= PNAME_NS PN_LOCAL PNAME_NS       ::= PN_PREFIX? ':' PN_LOCAL       ::= ( PN_CHARS_U | [0-9] ) ((PN_CHARS|'.')* PN_CHARS)? PN_CHARS       ::= PN_CHARS_U                  | '-' | [0-9] | #x00B7                  | [#x0300-#x036F] | [#x203F-#x2040] PN_CHARS_U     ::= PN_CHARS_BASE                  | '_' PN_CHARS_BASE ::= [A-Z] | [a-z] | [#x00C0-#x00D6] | [#x00D8-#x00F6]                  | [#x00F8-#x02FF] | [#x0370-#x037D] | [#x037F-#x1FFF]                  | [#x200C-#x200D] | [#x2070-#x218F] | [#x2C00-#x2FEF]                  | [#x3001-#xD7FF] | [#xF900-#xFDCF] | [#xFDF0-#xFFFD]                  | [#x10000-#xEFFFF] PN_PREFIX      ::= PN_CHARS_BASE ((PN_CHARS|'.')* PN_CHARS)? The more I look at CURIEs, the more my head hurts! The RIF specification allows prefixes and colons without local names, which surprised me. However, the CURIE Syntax 1.0 working group note specifically states that this form is supported…and then promptly provides a syntactic definition that seems to preclude it! However, on (much) deeper inspection, it appears that ‘ex1:’ (for example) is allowed, but would really represent a ‘fragment’ of the ‘reference’, rather than a prefix! Ouch! This is so completely ambiguous that it surely calls into question the whole CURIE specification.   In any case, RIF does not allow local names without a prefix. ·      Missing ‘External’ specifiers for built-in functions and predicates.  The EBNF specification enforces this for terms within frames, but does not appear to enforce (what I believe is) the correct use of External on built-in predicates. In any case, the running example only specifies ‘External’ once on the predicate in UnknownStatusRule. External() is required in several other places. ·      The List used on the LHS of UnknownStatusRule is comma-delimited. This is not supported by the EBNF definition. Similarly, the argument list of pred:list-contains is illegally comma-delimited. ·      Unnecessary use of conjunction around a single formula in DiscountRule. This is strictly legal in the EBNF, but redundant.   All the above issues concern the presentation syntax used in the running example. There are a few minor issues with the grammar itself. Note that Michael Kiefer stated in his paper “Rule Interchange Format: The Framework” that: “The presentation syntax of RIF … is an abstract syntax and, as such, it omits certain details that might be important for unambiguous parsing.” ·      The grammar cannot differentiate unambiguously between strategies and priorities on groups. A processor is forced to resolve this by detecting the use of IRIs and integers. This could easily be fixed in the grammar.   ·      The grammar cannot unambiguously parse the ‘->’ operator in frames. Specifically, ‘-’ characters are allowed in PN_LOCAL names and hence a parser cannot determine if ‘status->’ is (‘status’ ‘->’) or (‘status-’ ‘>’).   One way to fix this is to amend the PN_LOCAL production as follows: PN_LOCAL ::= ( PN_CHARS_U | [0-9] ) ((PN_CHARS|'.')* ((PN_CHARS)-('-')))? However, unilaterally changing the definition of this production, which is defined in the SPARQL Query Language for RDF specification, makes me uncomfortable. ·      I assume that the presentation syntax is case-sensitive. I couldn’t find this stated anywhere in the documentation, but function/predicate names do appear to be documented as being case-sensitive. ·      The EBNF does not specify whitespace handling. A couple of productions (RULE and ACTION_BLOCK) are crafted to enforce the use of whitespace. This is not necessary. It seems inconsistent with the rest of the specification and can cause parsing issues. In addition, the Const production exhibits whitespaces issues. The intention may have been to disallow the use of whitespace around ‘^^’, but any direct implementation of the EBNF will probably allow whitespace between ‘^^’ and the SYMSPACE. Of course, I am being a little nit-picking about all this. On the whole, the EBNF translated very smoothly and directly to ‘M’ (MGrammar) and proved to be fairly complete. I have encountered far worse issues when translating other EBNF specifications into usable grammars.   I can’t imagine there would be any difficulty in implementing the same grammar in Antlr, COCO/R, gppg, XText, Bison, etc. A general observation, which repeats a point made above, is that the use of parenthesis in the presentation syntax can feel inconsistent and un-intuitive.   It isn’t actually inconsistent, but I think the presentation syntax could be improved by adopting braces, rather than parenthesis, to delimit subordinate syntax elements in a similar way to so many programming languages. The familiarity of braces would communicate the structure of the syntax more clearly to people like me.  If braces were adopted, parentheses could be retained around ‘var (frame | ‘new()’) constructs in action blocks. This use of parenthesis feels very LISP-like, and I think that this is my issue. It’s as if the presentation syntax represents the deformed love-child of LISP and C. In some places (specifically, action blocks), parenthesis is used in a LISP-like fashion. In other places it is used like braces in C. I find this quite confusing. Here is a corrected version of the running example (Example 9.1) in compliant presentation syntax: Document(    Prefix( ex1 <http://example.com/2009/prd2> )    (* ex1:CheckoutRuleset *)  Group rif:forwardChaining (     (* ex1:GoldRule *)    Group 10 (      Forall ?customer such that And(?customer # ex1:Customer                                     ?customer[ex1:status->"Silver"])        (Forall ?shoppingCart such that ?customer[ex1:shoppingCart->?shoppingCart]           (If Exists ?value (And(?shoppingCart[ex1:value->?value]                                  External(pred:numeric-greater-than-or-equal(?value 2000))))            Then Do(Modify(?customer[ex1:status->"Gold"])))))      (* ex1:DiscountRule *)    Group (      Forall ?customer such that ?customer # ex1:Customer        (If Or( ?customer[ex1:status->"Silver"]                ?customer[ex1:status->"Gold"])         Then Do ((?s ?customer[ex1:shoppingCart-> ?s])                  (?v ?s[ex1:value->?v])                  Modify(?s [ex1:value->External(func:numeric-multiply (?v 0.95))]))))      (* ex1:NewCustomerAndWidgetRule *)    Group (      Forall ?customer such that And(?customer # ex1:Customer                                     ?customer[ex1:status->"New"] )        (If Exists ?shoppingCart ?item                   (And(?customer[ex1:shoppingCart->?shoppingCart]                        ?shoppingCart[ex1:containsItem->?item]                        ?item # ex1:Widget ) )         Then Do( (?s ?customer[ex1:shoppingCart->?s])                  (?val ?s[ex1:value->?val])                  (?voucher ?customer[ex1:voucher->?voucher])                  Retract(?customer[ex1:voucher->?voucher])                  Retract(?voucher)                  Modify(?s[ex1:value->External(func:numeric-multiply(?val 0.90))]))))      (* ex1:UnknownStatusRule *)    Group (      Forall ?customer such that ?customer # ex1:Customer        (If Not(Exists ?status                       (And(?customer[ex1:status->?status]                            External(pred:list-contains(List("New" "Bronze" "Silver" "Gold") ?status)) )))         Then Do( Execute(act:print(External(func:concat("New customer: " ?customer))))                  Assert(?customer[ex1:status->"New"]))))  ) )   I hope that helps someone out there :-)

• Five Key Strategies in Master Data Management

  - by david.butler(at)oracle.com

  Here is a very interesting Profit Magazine article on MDM: A recent customer survey reveals the deleterious effects of data fragmentation. by Trevor Naidoo, December 2010   Across industries and geographies, IT organizations have grown in complexity, whether due to mergers and acquisitions, or decentralized systems supporting functional or departmental requirements. With systems architected over time to support unique, one-off process needs, they are becoming costly to maintain, and the Internet has only further added to the complexity. Data fragmentation has become a key inhibitor in delivering flexible, user-friendly systems. The Oracle Insight team conducted a survey assessing customers' master data management (MDM) capabilities over the past two years to get a sense of where they are in terms of their capabilities. The responses, by 27 respondents from six different industries, reveal five key areas in which customers need to improve their data management in order to get better financial results. 1. Less than 15 percent of organizations surveyed understand the sources and quality of their master data, and have a roadmap to address missing data domains. Examples of the types of master data domains referred to are customer, supplier, product, financial and site. Many organizations have multiple sources of master data with varying degrees of data quality in each source -- customer data stored in the customer relationship management system is inconsistent with customer data stored in the order management system. Imagine not knowing how many places you stored your customer information, and whether a customer's address was the most up to date in each source. In fact, more than 55 percent of the respondents in the survey manage their data quality on an ad-hoc basis. It is important for organizations to document their inventory of data sources and then profile these data sources to ensure that there is a consistent definition of key data entities throughout the organization. Some questions to ask are: How do we define a customer? What is a product? How do we define a site? The goal is to strive for one common repository for master data that acts as a cross reference for all other sources and ensures consistent, high-quality master data throughout the organization. 2. Only 18 percent of respondents have an enterprise data management strategy to ensure that data is treated as an asset to the organization. Most respondents handle data at the department or functional level and do not have an enterprise view of their master data. The sales department may track all their interactions with customers as they move through the sales cycle, the service department is tracking their interactions with the same customers independently, and the finance department also has a different perspective on the same customer. The salesperson may not be aware that the customer she is trying to sell to is experiencing issues with existing products purchased, or that the customer is behind on previous invoices. The lack of a data strategy makes it difficult for business users to turn data into information via reports. Without the key building blocks in place, it is difficult to create key linkages between customer, product, site, supplier and financial data. These linkages make it possible to understand patterns. A well-defined data management strategy is aligned to the business strategy and helps create the governance needed to ensure that data stewardship is in place and data integrity is intact. 3. Almost 60 percent of respondents have no strategy to integrate data across operational applications. Many respondents have several disparate sources of data with no strategy to keep them in sync with each other. Even though there is no clear strategy to integrate the data (see #2 above), the data needs to be synced and cross-referenced to keep the business processes running. About 55 percent of respondents said they perform this integration on an ad hoc basis, and in many cases, it is done manually with the help of Microsoft Excel spreadsheets. For example, a salesperson needs a report on global sales for a specific product, but the product has different product numbers in different countries. Typically, an analyst will pull all the data into Excel, manually create a cross reference for that product, and then aggregate the sales. The exact same procedure has to be followed if the same report is needed the following month. A well-defined consolidation strategy will ensure that a central cross-reference is maintained with updates in any one application being propagated to all the other systems, so that data is synchronized and up to date. This can be done in real time or in batch mode using integration technology. 4. Approximately 50 percent of respondents spend manual efforts cleansing and normalizing data. Information stored in various systems usually follows different standards and formats, making it difficult to match the data. A customer's address can be stored in different ways using a variety of abbreviations -- for example, "av" or "ave" for avenue. Similarly, a product's attributes can be stored in a number of different ways; for example, a size attribute can be stored in inches and can also be entered as "'' ". These types of variations make it difficult to match up data from different sources. Today, most customers rely on manual, heroic efforts to match, cleanse, and de-duplicate data -- clearly not a scalable, sustainable model. To solve this challenge, organizations need the ability to standardize data for customers, products, sites, suppliers and financial accounts; however, less than 10 percent of respondents have technology in place to automatically resolve duplicates. It is no wonder, therefore, that we get communications about products we don't own, at addresses we don't reside, and using channels (like direct mail) we don't like. An all-too-common example of a potential challenge follows: Customers end up receiving duplicate communications, which not only impacts customer satisfaction, but also incurs additional mailing costs. Cleansing, normalizing, and standardizing data will help address most of these issues. 5. Only 10 percent of respondents have the ability to share data that was mastered in a master data hub. Close to 60 percent of respondents have efforts in place that profile, standardize and cleanse data manually, and the output of these efforts are stored in spreadsheets in various parts of the organization. This valuable information is not easily shared with the rest of the organization and, more importantly, this enriched information cannot be sent back to the source systems so that the data is fixed at the source. A key benefit of a master data management strategy is not only to clean the data, but to also share the data back to the source systems as well as other systems that need the information. Aside from the source systems, another key beneficiary of this data is the business intelligence system. Having clean master data as input to business intelligence systems provides more accurate and enhanced reporting.  Characteristics of Stellar MDM When deciding on the right master data management technology, organizations should look for solutions that have four main characteristics: enterprise-grade MDM performance complete technology that can be rapidly deployed and addresses multiple business issues end-to-end MDM process management with data quality monitoring and assurance pre-built MDM business relevant applications with data stores and workflows These master data management capabilities will aid in moving closer to a best-practice maturity level, delivering tremendous efficiencies and savings as well as revenue growth opportunities as a result of better understanding your customers.  Trevor Naidoo is a senior director in Industry Strategy and Insight at Oracle.

• Exalogic 2.0.1 Tea Break Snippets - Creating a ModifyJeOS VirtualBox

  - by The Old Toxophilist

  Following on from my previous blog entry "Modifying the Base Template" I decided to put together a quick blog to show how to create a small VirtualBox, guest, that can be used to execute the ModifyJeOS and hence edit you templates. One of the main advantages of this is that Templates can be created away from the Exalogic Environment. For the Guest OS I chose OEL 6u3 and decided to create it as a basic server because I did not require a graphical interface but it's a simple change to create it with a GUI. Required Software Virtual Box. Oracle Enterprise Linux. Creating the VM I'll assume that the reader is experienced with Virtual Box and installing OEL and hence will make this section brief. Create VirtualBox Guest Create a new VirtualBox Guest and select oracle Linux 64 bit. Follow through the create process and select Dynamic Disk Size and the default 12GB disk size. The actual image will be a lot smaller than this but the OEL install will fail with insufficient disk space if you attempt a smaller size. Once the guest has been created attach the previously downloaded OEL 6u3 iso to the cd drive and start the guest. Install OEL On starting the guest the system will boot off the associated OEL 6u3 iso and take you through the standard installation process. Select all the appropriate information but when you reach the installation type select Basic Server because we do not need that additional packages and only need to access through the command line interface. Complete the installation and reboot the Guest. At this point we now have a basic OEL server running. Installing Guest Add-ons Before we can easily access the Guest we will need to add the VirtualBox guest add-ons. These will provide better keyboard and mouse integration and allow access the shared folders on the host machine. Before we can do this we will need to do the following: Enable Networking. Install additional rpms.  To enable the networking (eth0), that appears to be disabled by default, we can execute: ifup eth0 This will start the eth0 connection but once the Guest is rebooted the network will be down again. To resolve this you will need to edit the /etc/sysconfig/network-scripts/ifcfg-eth0 file and change the ONBOOT parameter to "yes". Now we have enabled the network we will need to install a number of addition rpm. First we will need to configure the yum repository as follows: [ol6_latest] name=Oracle Linux $releasever Latest ($basearch) baseurl=http://public-yum.oracle.com/repo/OracleLinux/OL6/latest/$basearch/ gpgkey=http://public-yum.oracle.com/RPM-GPG-KEY-oracle-ol6 gpgcheck=1 enabled=1 [ol6_ga_base] name=Oracle Linux $releasever GA installation media copy ($basearch) baseurl=http://public-yum.oracle.com/repo/OracleLinux/OL6/0/base/$basearch/ gpgkey=http://public-yum.oracle.com/RPM-GPG-KEY-oracle-ol6 gpgcheck=1 enabled=0 [ol6_u1_base] name=Oracle Linux $releasever Update 1 installation media copy ($basearch) baseurl=http://public-yum.oracle.com/repo/OracleLinux/OL6/1/base/$basearch/ gpgkey=http://public-yum.oracle.com/RPM-GPG-KEY-oracle-ol6 gpgcheck=1 enabled=0 [ol6_u2_base] name=Oracle Linux $releasever Update 2 installation media copy ($basearch) baseurl=http://public-yum.oracle.com/repo/OracleLinux/OL6/2/base/$basearch/ gpgkey=http://public-yum.oracle.com/RPM-GPG-KEY-oracle-ol6 gpgcheck=1 enabled=0 [ol6_u3_base] name=Oracle Linux $releasever Update 3 installation media copy ($basearch) baseurl=http://public-yum.oracle.com/repo/OracleLinux/OL6/3/base/$basearch/ gpgkey=http://public-yum.oracle.com/RPM-GPG-KEY-oracle-ol6 gpgcheck=1 enabled=0 [ol6_UEK_latest] name=Latest Unbreakable Enterprise Kernel for Oracle Linux $releasever ($basearch) baseurl=http://public-yum.oracle.com/repo/OracleLinux/OL6/UEK/latest/$basearch/ gpgkey=http://public-yum.oracle.com/RPM-GPG-KEY-oracle-ol6 gpgcheck=1 enabled=1 [ol6_UEK_base] name=Unbreakable Enterprise Kernel for Oracle Linux $releasever ($basearch) baseurl=http://public-yum.oracle.com/repo/OracleLinux/OL6/UEK/base/$basearch/ gpgkey=http://public-yum.oracle.com/RPM-GPG-KEY-oracle-ol6 gpgcheck=1 enabled=0 Once the repository has been edited we will need to execute the following yum commands: yum update yum install gcc yum install kernel-uek-devel yum install kernel-devel yum install createrepo At this point we now have all the additional packages required to install the VirtualBox Guest Add-ons. So select Devices->InstallGuest Additions on you running guest: This will simply place the VirtualBoxGuestAdditions.iso in the virtual cd and we will need to execute the following before we can run them. mkdir /media/cdrom mount -t iso9660 -o ro /dev/cdrom /media/cdrom cd /media/cdrom/ ls ./VBoxLinuxAdditions.run This will initiate the install and kernel rebuild. What you will notice is that during the installation a Failed will be displayed but this is simply because we have no graphical components. At this point we the installation will also have added the vboxsf group to the system and to access any shared folders we will create our user will need to be a member of this group an so the next stage is to add the root user to this group as follows: usermod -G vboxsf root cat /etc/group cat /etc/passwd init 0 Now simply shutdown the guest and add the Shared folder within your guests settings. Install ModifyJeOS Once the shared folder has been added restart the guest and change directory into the shared folder (/media/sf_<folder name>). For the next step I am assuming the ModifyJeOS rpms are located in the shared folder. We can simply execute: rpm -ivh ovm-modify-jeos-1.1.0-17.el5.noarch.rpm # Test with modifyjeos Using ModifyJeOS I have a modified MountSystemImg.sh script that should be copied into the /root/bin directory (you may need to create this) and from here it can be executed from any location: MountSystemImg.sh #!/bin/sh # The script assumes it's being run from the directory containing the System.img # Export for later i.e. during unmount export LOOP=`losetup -f` export SYSTEMIMG=/mnt/elsystem export TEMPLATEDIR=`pwd` # Make Temp Mount Directory mkdir -p $SYSTEMIMG # Create Loop for the System Image losetup $LOOP System.img kpartx -a $LOOP mount /dev/mapper/`basename $LOOP`p2 $SYSTEMIMG #Change Dir into mounted Image cd $SYSTEMIMG echo "######################################################################" echo "### ###" echo "### Starting Bash shell for editing. When completed log out to ###" echo "### Unmount the System.img file. ###" echo "### ###" echo "######################################################################" echo bash cd ~ cd $TEMPLATEDIR umount $SYSTEMIMG kpartx -d $LOOP losetup -d $LOOP rm -rf $SYSTEMIMG This script will simple create a mount directory, mount the System.img and then start a new shell in the mounted directory. On exiting the shell it will unmount the System.img. It only requires that you execute the script in the directory containing the System.img. These can be created under the mounted shared directory. In the example below I have extracted the Base template within the shared folder and then renamed it OEL_40GB_ROOT before changing into that directory and executing the script.

• Solaris 11 SRU / Update relationship explained, and blackout period on delivery of new bug fixes eliminated

  - by user12244672

  Relationship between SRUs and Update releases As you may know, Support Repository Updates (SRUs) for Oracle Solaris 11 are released monthly and are available to customers with an appropriate support contract.  SRUs primarily deliver bug fixes.  They may also deliver low risk feature enhancements. Solaris Update are typically released once or twice a year, containing support for new hardware, new software feature enhancements, and all bug fixes available at the time the Update content was finalized.  They also contain a significant number of new bug fixes, for issues found internally in Oracle and complex customer bug fixes which  require significant "soak" time to ensure their efficacy prior to release. Changes to SRU and Update Naming Conventions We're changing the naming convention of Update releases from a date based format such as Oracle Solaris 10 8/11 to a simpler "dot" version numbering, e.g. Oracle Solaris 11.1. Oracle Solaris 11 11/11 (i.e. the initial Oracle Solaris 11 release) may be referred to as 11.0. SRUs will simply be named as "dot.dot" releases, e.g. Oracle Solaris 11.1.1, for SRU1 after Oracle Solaris 11.1. Many Oracle products and infrastructure tools such as BugDB and MOS are tailored towards this "dot.dot" style of release naming, so these name changes align Oracle Solaris with these conventions. No Blackout Periods on Bug Fix Releases The Oracle Solaris 11 release process has been enhanced to eliminate blackout periods on the delivery of new bug fixes to customers. Previously, Oracle Solaris Updates were a superset of all preceding bug fix deliveries.  This made for a very simple update message - that which releases later is always a superset of that which was delivered previously. However, it had a downside.  Once the contents of an Update release were frozen prior to release, the release of new bug fixes for customer issues was also frozen to maintain the Update's superset relationship. Since the amount of change allowed into the final internal builds of an Update release is reduced to mitigate risk, this throttling back also impacted the release of new bug fixes to customers. This meant that there was effectively a 6 to 9 week hiatus on the release of new bug fixes prior to the release of each Update.  That wasn't good for customers awaiting critical bug fixes. We've eliminated this hiatus on the delivery of new bug fixes in Oracle Solaris 11 by allowing new bug fixes to continue to be released in SRUs even after the contents of the next Update release have been frozen. The release of SRUs will remain contiguous, with the first SRU released after the Update release effectively being a superset of both the the Update release and all preceding SRUs*.  That is, later SRUs are supersets of the content of previous SRUs. Therefore, the progression path from the final SRUs prior to the Update release is to the first SRU after the Update release, rather than to the Update release itself. The timeline / logical sequence of releases can be shown as follows: Updates: 11.0                                                11.1                               11.2     etc.                  \                                                         \                                    \ SRUs:       11.0.1, 11.0.2,...,11.0.12, 11.0.13, 11.1.1, 11.1.2,...,11.1.x, 11.2.1, etc. For example, for systems with Oracle Solaris 11 11/11 SRU12.4 or later installed, the recommended update path is to Oracle Solaris 11.1.1 (i.e. SRU1 after Solaris 11.1) or later rather than to the Solaris 11.1 release itself.  This will ensure no bug fixes are "lost" during the update. If for any reason you do wish to update from SRU12.4 or later to the 11.1 release itself - for example to update a test system - the instructions to do so are in the SRU12.4 README, https://updates.oracle.com/Orion/Services/download?type=readme&aru=15564533 For systems with Oracle Solaris 11 11/11 SRU11.4 or earlier installed, customers can update to either the 11.1 release or any 11.1 SRU as both will be supersets of their current version. Please do read the README of the SRU you are updating to, as it will contain important installation instructions which will save you time and effort. *Nerdy details: SRUs only contain the latest change delta relative to the Update on which they are based.  Their dependencies will, however, effectively pull in the Update content.  Customers maintaining a local Repo (e.g. behind their firewall), need to add both the 11.1 content and the relevant SRU content to their Repo, to enable the SRU's dependencies to be resolved.  Both will be available from the standard Support Repo and from MOS.  This is no different to existing SRUs for Oracle Solaris 11.0, whereby you may often get away with using just the SRU content to update, but the original 11.0 content may be needed in the Repo to resolve dependencies.

• Windows Azure Virtual Machine Readiness and Capacity Assessment for SQL Server

  - by SQLOS Team

  Windows Azure Virtual Machine Readiness and Capacity Assessment for Windows Server Machine Running SQL Server With the release of MAP Toolkit 8.0 Beta, we have added a new scenario to assess your Windows Azure Virtual Machine Readiness. The MAP 8.0 Beta performs a comprehensive assessment of Windows Servers running SQL Server to determine you level of readiness to migrate an on-premise physical or virtual machine to Windows Azure Virtual Machines. The MAP Toolkit then offers suggested changes to prepare the machines for migration, such as upgrading the operating system or SQL Server. MAP Toolkit 8.0 Beta is available for download here Your participation and feedback is very important to make the MAP Toolkit work better for you. We encourage you to participate in the beta program and provide your feedback at [email protected] or through one of our surveys. Now, let’s walk through the MAP Toolkit task for completing the Windows Azure Virtual Machine assessment and capacity planning. The tasks include the following: Perform an inventory View the Windows Azure VM Readiness results and report Collect performance data for determine VM sizing View the Windows Azure Capacity results and report Perform an inventory: 1. To perform an inventory against a single machine or across a complete environment, choose Perform an Inventory to launch the Inventory and Assessment Wizard as shown below: 2. After the Inventory and Assessment Wizard launches, select either the Windows computers or SQL Server scenario to inventory Windows machines. HINT: If you don’t care about completely inventorying a machine, just select the SQL Server scenario. Click Next to Continue. 3. On the Discovery Methods page, select how you want to discover computers and then click Next to continue. Description of Discovery Methods: Use Active Directory Domain Services -- This method allows you to query a domain controller via the Lightweight Directory Access Protocol (LDAP) and select computers in all or specific domains, containers, or OUs. Use this method if all computers and devices are in AD DS. Windows networking protocols --  This method uses the WIN32 LAN Manager application programming interfaces to query the Computer Browser service for computers in workgroups and Windows NT 4.0–based domains. If the computers on the network are not joined to an Active Directory domain, use only the Windows networking protocols option to find computers. System Center Configuration Manager (SCCM) -- This method enables you to inventory computers managed by System Center Configuration Manager (SCCM). You need to provide credentials to the System Center Configuration Manager server in order to inventory the managed computers. When you select this option, the MAP Toolkit will query SCCM for a list of computers and then MAP will connect to these computers. Scan an IP address range -- This method allows you to specify the starting address and ending address of an IP address range. The wizard will then scan all IP addresses in the range and inventory only those computers. Note: This option can perform poorly, if many IP addresses aren’t being used within the range. Manually enter computer names and credentials -- Use this method if you want to inventory a small number of specific computers. Import computer names from a files -- Using this method, you can create a text file with a list of computer names that will be inventoried. 4. On the All Computers Credentials page, enter the accounts that have administrator rights to connect to the discovered machines. This does not need to a domain account, but needs to be a local administrator. I have entered my domain account that is an administrator on my local machine. Click Next after one or more accounts have been added. NOTE: The MAP Toolkit primarily uses Windows Management Instrumentation (WMI) to collect hardware, device, and software information from the remote computers. In order for the MAP Toolkit to successfully connect and inventory computers in your environment, you have to configure your machines to inventory through WMI and also allow your firewall to enable remote access through WMI. The MAP Toolkit also requires remote registry access for certain assessments. In addition to enabling WMI, you need accounts with administrative privileges to access desktops and servers in your environment. 5. On the Credentials Order page, select the order in which want the MAP Toolkit to connect to the machine and SQL Server. Generally just accept the defaults and click Next. 6. On the Enter Computers Manually page, click Create to pull up at dialog to enter one or more computer names. 7. On the Summary page confirm your settings and then click Finish. After clicking Finish the inventory process will start, as shown below: Windows Azure Readiness results and report After the inventory progress has completed, you can review the results under the Database scenario. On the tile, you will see the number of Windows Server machine with SQL Server that were analyzed, the number of machines that are ready to move without changes and the number of machines that require further changes. If you click this Azure VM Readiness tile, you will see additional details and can generate the Windows Azure VM Readiness Report. After the report is generated, select View | Saved Reports and Proposals to view the location of the report. Open up WindowsAzureVMReadiness* report in Excel. On the Windows tab, you can see the results of the assessment. This report has a column for the Operating System and SQL Server assessment and provides a recommendation on how to resolve, if there a component is not supported. Collect Performance Data Launch the Performance Wizard to collect performance information for the Windows Server machines that you would like the MAP Toolkit to suggest a Windows Azure VM size for. Windows Azure Capacity results and report After the performance metrics are collected, the Azure VM Capacity title will display the number of Virtual Machine sizes that are suggested for the Windows Server and Linux machines that were analyzed. You can then click on the Azure VM Capacity tile to see the capacity details and generate the Windows Azure VM Capacity Report. Within this report, you can view the performance data that was collected and the Virtual Machine sizes.   MAP Toolkit 8.0 Beta is available for download here Your participation and feedback is very important to make the MAP Toolkit work better for you. We encourage you to participate in the beta program and provide your feedback at [email protected] or through one of our surveys.

• Ubuntu 12.04 + Wifi not working

  - by user171154

  i'm having problems connecting over wireless. At the moment, I'm using wicd. It seems to get stuck on "Verifying AP association...". Without wicd I can get the connection up and ping the Net - but if I take eth0 down (ifconfig eth0 down), my wireless goes away too (same result if I unplug the wire instead). wicd is the only way I can bring eth0 back (which is the main reason I'm using it) - ifconfig eth0 and/or ifup eth0 do not re-enable the connection (I just discovered it leaves out the gateway. Adding the gateway back in re-enables the connection including wifi; I didn't want to delete the info about wicd above in case it gives someone an idea.) Doing it manually, despite the errors (which it would be nice to also resolve) - allows me to ping the outside world: ifup wlan0 ioctl[SIOCSIWENCODEEXT]: Invalid argument ioctl[SIOCSIWENCODEEXT]: Invalid argument ssh stop/waiting ssh start/running, process 17336 ping -I wlan0 -c 4 8.8.8.8 PING 8.8.8.8 (8.8.8.8) from 192.168.0.12 wlan0: 56(84) bytes of data. 64 bytes from 8.8.8.8: icmp_req=1 ttl=43 time=48.8 ms 64 bytes from 8.8.8.8: icmp_req=2 ttl=43 time=47.9 ms 64 bytes from 8.8.8.8: icmp_req=3 ttl=43 time=48.7 ms 64 bytes from 8.8.8.8: icmp_req=4 ttl=43 time=53.2 ms --- 8.8.8.8 ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 3003ms rtt min/avg/max/mdev = 47.975/49.711/53.235/2.063 ms #

• SpringMvc java.lang.NullPointerException When Posting Form To Server [closed]

  - by dev_darin

  I have a form with a user name field on it when i tab out of the field i use a RESTFUL Web Service that makes a call to a handler method in the controller. The method makes a call to a DAO class that checks the database if the user name exists. This works fine, however when the form is posted to the server i call the same exact function i would call in the handler method however i get a java.lang.NullPointerException when it accesses the class that makes a call to the DAO object. So it does not even access the DAO object the second time. I have exception handlers around the calls in all my classes that makes calls. Any ideas as to whats happening here why i would get the java.lang.NullPointerException the second time the function is called.Does this have anything to do with Spring instantiating DAO classes using a Singleton method or something to that effect? What can be done to resolve this? This is what happens the First Time The Method is called using the Web Service(this is suppose to happen): 13011 [http-8084-2] INFO com.crimetrack.jdbc.JdbcOfficersDAO - Inside jdbcOfficersDAO 13031 [http-8084-2] DEBUG org.springframework.jdbc.core.JdbcTemplate - Executing prepared SQL query 13034 [http-8084-2] DEBUG org.springframework.jdbc.core.JdbcTemplate - Executing prepared SQL statement [SELECT userName FROM crimetrack.tblofficers WHERE userName = ?] 13071 [http-8084-2] DEBUG org.springframework.jdbc.datasource.DataSourceUtils - Fetching JDBC Connection from DataSource 13496 [http-8084-2] DEBUG org.springframework.jdbc.core.StatementCreatorUtils - Setting SQL statement parameter value: column index 1, parameter value [adminz], value class [java.lang.String], SQL type unknown 13534 [http-8084-2] DEBUG org.springframework.jdbc.datasource.DataSourceUtils - Returning JDBC Connection to DataSource 13537 [http-8084-2] INFO com.crimetrack.jdbc.JdbcOfficersDAO - No username was found in exception 13537 [http-8084-2] INFO com.crimetrack.service.ValidateUserNameManager - UserName :adminz does NOT exist The Second time When The Form Is 'Post' and a validation method handles the form and calls the same method the web service would call: 17199 [http-8084-2] INFO com.crimetrack.service.OfficerRegistrationValidation - UserName is not null so going to check if its valid for :adminz 17199 [http-8084-2] INFO com.crimetrack.service.OfficerRegistrationValidation - User Name in try.....catch block is adminz 17199 [http-8084-2] INFO com.crimetrack.service.ValidateUserNameManager - Inside Do UserNameExist about to validate with username : adminz 17199 [http-8084-2] INFO com.crimetrack.service.ValidateUserNameManager - UserName :adminz EXCEPTION OCCURED java.lang.NullPointerException ValidateUserNameManager.java public class ValidateUserNameManager implements ValidateUserNameIFace { private OfficersDAO officerDao;

• Displaylink USB show "Logo / Loading" on monitor

  - by Ken Le

  I tried with this problem for 2 years already. LOL, today, I install Ubuntu for I have to resolve it or I will back to stupid Windows 7. First, I have 3 monitors. My graphic card is support dual ( ATI Radeon ), so I have no problem on extend those multi monitor on VGA and DVI. The 3rd monitor is Displaylink USB. After installed everything required, when I reboot, the displaylink monitor show "Ubuntu ...." like logo / loading screen. I go to System Display , Detect monitor, it only show my 1st and 2nd, NO 3RD Displaylink. I can move my mouse between those 1st & 2nd, but the 3rd is only show the Ubuntu Screen. I press Ctrl+Alt+1, then screen switch to Displaylink USB 3RD monitor, but its "Terminal" not a desktop.

• Clouds Everywhere But not a Drop of Rain – Part 3

  - by sxkumar

  I was sharing with you how a broad-based transformation such as cloud will increase agility and efficiency of an organization if process re-engineering is part of the plan.  I have also stressed on the key enterprise requirements such as “broad and deep solutions, “running your mission critical applications” and “automated and integrated set of capabilities”. Let me walk you through some key cloud attributes such as “elasticity” and “self-service” and what they mean for an enterprise class cloud. I will also talk about how we at Oracle have taken a very enterprise centric view to developing cloud solutions and how our products have been specifically engineered to address enterprise cloud needs. Cloud Elasticity and Enterprise Applications Requirements Easy and quick scalability for a short-period of time is the signature of cloud based solutions. It is this elasticity that allows you to dynamically redistribute your resources according to business priorities, helps increase your overall resource utilization, and reduces operational costs by allowing you to get the most out of your existing investment. Most public clouds are offering a instant provisioning mechanism of compute power (CPU, RAM, Disk), customer pay for the instance-hours(and bandwidth) they use, adding computing resources at peak times and removing them when they are no longer needed. This type of “just-in-time” serving of compute resources is well known for mid-tiers “state less” servers such as web application servers and web servers that just need another machine to start and run on it but what does it really mean for an enterprise application and its underlying data? Most enterprise applications are not as quite as “state less” and justifiably so. As such, how do you take advantage of cloud elasticity and make it relevant for your enterprise apps? This is where Cloud meets Grid Computing. At Oracle, we have invested enormous amount of time, energy and resources in creating enterprise grid solutions. All our technology products offer built-in elasticity via clustering and dynamic scaling. With products like Real Application Clusters (RAC), Automatic Storage Management, WebLogic Clustering, and Coherence In-Memory Grid, we allow all your enterprise applications to benefit from Cloud elasticity –both vertically and horizontally - without requiring any application changes. A number of technology vendors take a rather simplistic route of starting up additional or removing unneeded VM as the "Cloud Scale-Out" solution. While this may work for stateless mid-tier servers where load balancers can handle the addition and remove of instances transparently but following a similar approach for the database tier - often called as "database sharding" - requires significant application modification and typically does not work with off the shelf packaged applications. Technologies like Oracle Database Real Application Clusters, Automatic Storage Management, etc. on the other hand bring the benefits of incremental scalability and on-demand elasticity to ANY application by providing a simplified abstraction layers where the application does not need deal with data spread over multiple database instances. Rather they just talk to a single database and the database software takes care of aggregating resources across multiple hardware components. It is the technologies like these that truly make a cloud solution relevant for enterprises.  For customers who are looking for a next generation hardware consolidation platform, our engineered systems (e.g. Exadata, Exalogic) not only provide incredible amount of performance and capacity, they also reduce the data center complexity and simplify operations. Assemble, Deploy and Manage Enterprise Applications for Cloud Products like Oracle Virtual assembly builder (OVAB) resolve the complex problem of bringing the cloud speed to complex multi-tier applications. With assemblies, you can not only provision all components of a multi-tier application and wire them together by push of a button, other aspects of application lifecycle, such as real-time application testing, scale-up/scale-down, performance and availability monitoring, etc., are also automated using Oracle Enterprise Manager.  An essential criteria for an enterprise cloud to succeed is the ability to ensure business service levels especially when business users have either full visibility on the usage cost with a “show back” or a “charge back”. With Oracle Enterprise Manager 12c, we have created the most comprehensive cloud management solution in the industry that is capable of managing business service levels “applications-to-disk” in a enterprise private cloud – all from a single console. It is the only cloud management platform in the industry that allows you to deliver infrastructure, platform and application cloud services out of the box. Moreover, it offers integrated and complete lifecycle management of the cloud - including planning and set up, service delivery, operations management, metering and chargeback, etc .  Sounds unbelievable? Well, just watch this space for more details on how Oracle Enterprise Manager 12c is the nerve center of Oracle Cloud! Our cloud solution portfolio is also the broadest and most deep in the industry  - covering public, private, hybrid, Infrastructure, platform and applications clouds. It is no coincidence therefore that the Oracle Cloud today offers the most comprehensive set of public cloud services in the industry.  And to a large part, this has been made possible thanks to our years on investment in creating cloud enabling technologies.  Summary  But the intent of this blog post isn't to dwell on how great our solutions are (these are just some examples to illustrate how we at Oracle have approached this problem space). Rather it is to help you ask the right questions before you embark on your cloud journey.  So to summarize, here are the key takeaways.       It is critical that you are clear on why you are building the cloud. Successful organizations keep business benefits as the first and foremost cloud objective. On the other hand, those who approach this purely as a technology project are more likely to fail. Think about where you want to be in 3-5 years before you get started. Your long terms objectives should determine what your first step ought to be. As obvious as it may seem, more people than not make the first move without knowing where they are headed.  Don’t make the mistake of equating cloud to virtualization and Infrastructure-as-a-Service (IaaS). Spinning a VM on-demand will give some short term relief to your IT staff but is unlikely to solve your larger business problems. As such, even if IaaS is your first step towards a more comprehensive cloud, plan the roadmap around those higher level services before you begin. And ask your vendors on how they are going to be your partners in this journey. Capabilities like self-service access and chargeback/showback are absolutely critical if you really expect your cloud to be transformational. Your business won't see the full benefits of the cloud until it empowers them with same kind of control and transparency that they are used to while using a public cloud service.  Evaluate the benefits of integration, as opposed to blindly following the best-of-breed strategy. Integration is a huge challenge and more so in a cloud environment. There are enormous costs associated with stitching a solution out of disparate components and even more in maintaining it. Hope you found these ideas helpful. Looking forward to hearing your thoughts and experiences.

• How to Plug a Small Hole in NetBeans JSF (Join Table) Code Generation

  - by MarkH

  I was asked recently to provide an assist with designing and building a small-but-vital application that had at its heart some basic CRUD (Create, Read, Update, & Delete) functionality, built upon an Oracle database, to be accessible from various locations. Working from the stated requirements, I fleshed out the basic application and database designs and, once validated, set out to complete the first iteration for review. Using SQL Developer, I created the requisite tables, indices, and sequences for our first run. One of the tables was a many-to-many join table with three fields: one a primary key for that table, the other two being primary keys for the other tables, represented as foreign keys in the join table. Here is a simplified example of the trio of tables: Once the database was in decent shape, I fired up NetBeans to let it have first shot at the code. NetBeans does a great job of generating a mountain of essential code, saving developers what must be millions of hours of effort each year by building a basic foundation with a few clicks and keystrokes. Lest you think it (or any tool) can do everything for you, however, occasionally something tosses a paper clip into the delicate machinery and makes you open things up to fix them. Join tables apparently qualify.  :-) In the case above, the entity class generated for the join table (New Entity Classes from Database) included an embedded object consisting solely of the two foreign key fields as attributes, in addition to an object referencing each one of the "component" tables. The Create page generated (New JSF Pages from Entity Classes) worked well to a point, but when trying to save, we were greeted with an error: Transaction aborted. Hmm. A quick debugger session later and I'd identified the issue: when trying to persist the new join-table object, the embedded "foreign-keys-only" object still had null values for its two (required value) attributes...even though the embedded table objects had populated key attributes. Here's the simple fix: In the join-table controller class, find the public String create() method. It will look something like this:     public String create() {        try {            getFacade().create(current);            JsfUtil.addSuccessMessage(ResourceBundle.getBundle("/Bundle").getString("JoinEntityCreated"));            return prepareCreate();        } catch (Exception e) {            JsfUtil.addErrorMessage(e, ResourceBundle.getBundle("/Bundle").getString("PersistenceErrorOccured"));            return null;        }    } To restore balance to the force, modify the create() method as follows (changes in red):     public String create() {         try {            // Add the next two lines to resolve:            current.getJoinEntityPK().setTbl1id(current.getTbl1().getId().toBigInteger());            current.getJoinEntityPK().setTbl2id(current.getTbl2().getId().toBigInteger());            getFacade().create(current);            JsfUtil.addSuccessMessage(ResourceBundle.getBundle("/Bundle").getString("JoinEntityCreated"));            return prepareCreate();        } catch (Exception e) {            JsfUtil.addErrorMessage(e, ResourceBundle.getBundle("/Bundle").getString("PersistenceErrorOccured"));            return null;        }    } I'll be refactoring this code shortly, but for now, it works. Iteration one is complete and being reviewed, and we've met the milestone. Here's to happy endings (and customers)! All the best,Mark

• Accessing your web server via IPv6

  Being able to run your systems on IPv6, have automatic address assignment and the ability to resolve host names are the necessary building blocks in your IPv6 network infrastructure. Now, that everything is in place it is about time that we are going to enable another service to respond to IPv6 requests. The following article will guide through the steps on how to enable Apache2 httpd to listen and respond to incoming IPv6 requests. This is the fourth article in a series on IPv6 configuration: Configure IPv6 on your Linux system DHCPv6: Provide IPv6 information in your local network Enabling DNS for IPv6 infrastructure Accessing your web server via IPv6 Piece of advice: This is based on my findings on the internet while reading other people's helpful articles and going through a couple of man-pages on my local system. Surfing the web - IPv6 style Enabling IPv6 connections in Apache 2 is fairly simply. But first let's check whether your system has a running instance of Apache2 or not. You can check this like so: $ service apache2 status Apache2 is running (pid 2680). In case that you got a 'service unknown' you have to install Apache to proceed with the following steps: $ sudo apt-get install apache2 Out of the box, Apache binds to all your available network interfaces and listens to TCP port 80. To check this, run the following command: $ sudo netstat -lnptu | grep "apache2\W*$"tcp6       0      0 :::80                   :::*                    LISTEN      28306/apache2 In this case Apache2 is already binding to IPv6 (and implicitly to IPv4). If you only got a tcp output, then your HTTPd is not yet IPv6 enabled. Check your Listen directive, depending on your system this might be in a different location than the default in Ubuntu. $ sudo nano /etc/apache2/ports.conf # If you just change the port or add more ports here, you will likely also# have to change the VirtualHost statement in# /etc/apache2/sites-enabled/000-default# This is also true if you have upgraded from before 2.2.9-3 (i.e. from# Debian etch). See /usr/share/doc/apache2.2-common/NEWS.Debian.gz and# README.Debian.gzNameVirtualHost *:80Listen 80<IfModule mod_ssl.c>    # If you add NameVirtualHost *:443 here, you will also have to change    # the VirtualHost statement in /etc/apache2/sites-available/default-ssl    # to <VirtualHost *:443>    # Server Name Indication for SSL named virtual hosts is currently not    # supported by MSIE on Windows XP.    Listen 443</IfModule><IfModule mod_gnutls.c>    Listen 443</IfModule> Just in case that you don't have a ports.conf file, look for it like so: $ cd /etc/apache2/$ fgrep -r -i 'listen' ./* And modify the related file instead of the ports.conf. Which most probably might be either apache2.conf or httpd.conf anyways. Okay, please bear in mind that Apache can only bind once on the same interface and port. So, eventually, you might be interested to add another port which explicitly listens to IPv6 only. In that case, you would add the following in your configuration file: Listen 80Listen [2001:db8:bad:a55::2]:8080 But this is completely optional... Anyways, just to complete all steps, you save the file, and then check the syntax like so: $ sudo apache2ctl configtestSyntax OK Ok, now let's apply the modifications to our running Apache2 instances: $ sudo service apache2 reload * Reloading web server config apache2   ...done. $ sudo netstat -lnptu | grep "apache2\W*$"                                                                                               tcp6       0      0 2001:db8:bad:a55:::8080 :::*                    LISTEN      5922/apache2    tcp6       0      0 :::80                   :::*                    LISTEN      5922/apache2 There we have two daemons running and listening to different TCP ports. Now, that the basics are in place, it's time to prepare any website to respond to incoming requests on the IPv6 address. Open up any configuration file you have below your sites-enabled folder. $ ls -al /etc/apache2/sites-enabled/... $ sudo nano /etc/apache2/sites-enabled/000-default <VirtualHost *:80 [2001:db8:bad:a55::2]:8080>        ServerAdmin [email protected]        ServerName server.ios.mu        ServerAlias server Here, we have to check and modify the VirtualHost directive and enable it to respond to the IPv6 address and port our web server is listening to. Save your changes, run the configuration test and reload Apache2 in order to apply your modifications. After successful steps you can launch your favourite browser and navigate to your IPv6 enabled web server. Accessing an IPv6 address in the browser That looks like a successful surgery to me... Note: In case that you received a timeout, check whether your client is operating on IPv6, too.

• Are you reporting Visual Studio 2012 issues to Microsoft correctly?

  - by Tarun Arora

  Issues you may run into while using Visual Studio need to be reported to the Microsoft Product Team via the Microsoft connect site. The Microsoft team then tries to reproduce the issue using the details provided by you. If the information you provide isn’t sufficient to reproduce the issue the team tries to contact you for specifics, this not only increases the cycle time to resolution but the lack of communication also results in issues not being resolved. So, when I report an issue one part of me tells me to include as much detail about the issue as I can clubbing screen shots, repo steps, system information, visual studio version information,… the other half tells me this is so time consuming, leave it for now and come back to fill all these details later. Reporting a bug but not including the supporting information is an invitation to excuses like …     Microsoft has absolutely changed this experience for VS 2012. The Microsoft Visual Studio Feedback tool is designed to simplify the process of providing feedback and reporting issues to Microsoft that you may encounter while using Microsoft Visual Studio 2012. Note – The Microsoft Visual Studio 2012 Feedback client currently only works for VS 2012 and not any other versions of Visual Studio. Setting up the Microsoft Visual Studio 2012 Feedback client Open Visual Studio, from the Tools menu select Extension and Updates. In the Extension and Updates window, click Online from the left pane and search using the text ‘feedback’, download and Install Microsoft Visual Studio 2012 Feedback Tool by following the instructions from the wizard. Note - Restarting Visual Studio after the install is a must! How to report a bug for Visual Studio 2012? Click on the Help menu and choose Report a Bug You should see an icon Microsoft Visual Studio 2012 Feedback Tool come up in the system tray icon area You’ll need to accept the Privacy statement. You have the option of reporting the feedback as private or public. Microsoft works with several Partners, MVP’s and Vendors who get access to early bits of Microsoft products for valuation. This is where it becomes essential to report the feedback privately. I would choose the Public option otherwise. After all if it’s out there in the public, others can discover and add to it easily. You now have the option to report a new issue or add to an existing issue. Should you choose to add to an existing issue you should have the feedback ID of the issue available. This can be obtained from the Microsoft Connect site. For now I am going to focus on reporting a new feedback privately. Filling out the feedback details You will notice that VsInfo.xml and DxDiagOutput.txt are automatically attached as you enter this screen (more on that later).  Feedback Type Choose the feedback type from (Performance, Hang, Crash, Other) Note – The record button will only be enabled once you have enabled once you have chosen the feedback type, Bug-repro recording is not available for Windows Server 2008.     Effective Title and Description Enter a title that helps us differentiate the bug when it appears in a list, so that we can group it with any related bugs, assign it to a developer more effectively, and resolve it more quickly. Example: Imagine that you are submitting a bug because you tried to install Service Pack 1 and got a message that Visual Studio is not installed even though it is. Helpful:  Installed Visual Studio version not detected during Service Pack 1 setup. Not helpful:  Service Pack 1 problem. Tip: Write the problem description first, and then distil it to create a title. Example Description: Helpful: When I run Service Pack 1 Setup, I get the message "No Visual Studio version is detected" even though I have Visual Studio 2010 Ultimate and Visual C++ 2010 Express installed on my machine. Even though I uninstalled both editions, and then first reinstalled Ultimate and then Express, I still get the message. Record: Becoming a first class citizen Often a repro report is invaluable to describe and decipher the issue. Please use this feature to send actionable feedback. The record repro feature works differently depending on the feedback type you selected. Please find below details for each recording option. You can start recording simply by selecting a feedback type, and clicking on the “Record” button. When "Performance" is the bug type: When the Microsoft Visual Studio trace recorder starts, perform the actions that show the performance problem you want to report and then click on the "Stop Recording" button as soon as you experience the performance problem. Because the tool optimizes trace collection, you can run it for as long as it takes to show the problem, up to two hours. Note that, you need to stop recording as soon as the performance issue occurs, because the tool captures only the last couple minutes of your actions to optimize the trace collection. After you stop the recording, the tool takes up to two minutes to assemble the data and attach an ETLTrace.zip file to your bug report. The data includes information about Windows events and the Visual Studio code path. Note that, running the Microsoft Visual Studio trace recorder requires elevated user privilege. When "Crash" is the bug type: When the dialog box appears, select the running Visual Studio instance for which you want to show the steps that cause a crash. When the crash occurs, click on the "Stop Record" button. After you do this, two files are attached to your bug report - an AutomaticCrashDump.zip file that contains information about the crash and a ReproSteps.zip file that shows the repro steps. Repro steps are captured by Windows Problem Steps Recorder. Note that, you can pause the recording, and resume later, or for a specific step, you can add additional comments. When "Hang" is the bug type: The process for recording the steps that cause a hang resembles the one for crashes. The difference is, you can even collect a dump file after the VS hangs; start the VSFT either from the system tray or by starting a new instance of VS, select "Hang" as feedback type and click on the "Record" button. You will be prompted which VS to collect dump about, select the VS instance that hanged. VSFT collects a dump file regarding the hang, called MiniDump.zip, and attaches to your bug report. When "Other" is the bug type: When the problem step recorder starts, perform the actions that show the issue you want to report and then choose the "Stop” button. You can pause the recording, and resume later, or for a specific step, you can add additional comments. Once you’re done, ReproSteps.zip is added to your bug report. Pre-attached files It is essential for Microsoft to know what version of the the product are you currently using and what is the current configuration of your system. Note – The total size of all attachments in a bug report cannot exceed 2 GB, and every uncompressed attachment must be smaller than 512 MB. We recommend that you assemble all of your attachments, compress them together into a .zip file, and then attach the .zip file. Taking a screenshot Associate a screen shot by clicking the Take screenshot button, choose either the entire desktop, the specific monitor (useful if you are working in a multi monitor configuration) or the specific window in question. And finally … click Submit If you need further help, more details can be found here. You can view your feedback online by using the following URL “">https://connect.microsoft.com/VisualStudio/SearchResults.aspx?SearchQuery=<feedbackId>” Happy bug logging

• EF4 POCO WCF Serialization problems (no lazy loading, proxy/no proxy, circular references, etc)

  - by kdawg

  OK, I want to make sure I cover my situation and everything I've tried thoroughly. I'm pretty sure what I need/want can be done, but I haven't quite found the perfect combination for success. I'm utilizing Entity Framework 4 RTM and its POCO support. I'm looking to query for an entity (Config) that contains a many-to-many relationship with another entity (App). I turn off lazy loading and disable proxy creation for the context and explicitly load the navigation property (either through .Include() or .LoadProperty()). However, when the navigation property is loaded (that is, Apps is loaded for a given Config), the App objects that were loaded already contain references to the Configs that have been brought to memory. This creates a circular reference. Now I know the DataContractSerializer that WCF uses can handle circular references, by setting the preserveObjectReferences parameter to true. I've tried this with a couple of different attribute implementations I've found online. It is needed to prevent the "the object graph contains circular references and cannot be serialized" error. However, it doesn't prevent the serialization of the entire graph, back and forth between Config and App. If I invoke it via WcfTestClient.exe, I get a stackoverflow (ha!) exception from the client and I'm hosed. I get different results from different invocation environments (C# unit test with a local reference to the web service appears to work ok though I still can drill back and forth between Configs and Apps endlessly, but calling it from a coldfusion environment only returns the first Config in the list and errors out on the others.) My main goal is to have a serialized representation of the graph I explicitly load from EF (ie: list of Configs, each with their Apps, but no App back to Config navigation.) NOTE: I've also tried using the ProxyDataContractResolver technique and keeping the proxy creation enabled from my context. This blows up complaining about unknown types encountered. I read that the ProxyDataContractResolver didn't fully work in Beta2, but should work in RTM. For some reference, here is roughly how I'm querying the data in the service: var repo = BootStrapper.AppCtx["AppMeta.ConfigRepository"] as IRepository<Config>; repo.DisableLazyLoading(); repo.DisableProxyCreation(); //var temp2 = repo.Include(cfg => cfg.Apps).Where(cfg => cfg.Environment.Equals(environment)).ToArray(); var temp2 = repo.FindAll(cfg => cfg.Environment.Equals(environment)).ToArray(); foreach (var cfg in temp2) { repo.LoadProperty(cfg, c => c.Apps); } return temp2; I think the crux of my problem is when loading up navigation properties for POCO objects from Entity Framework 4, it prepopulates navigation properties for objects already in memory. This in turn hoses up the WCF serialization, despite every effort made to properly handle circular references. I know it's a lot of information, but it's really standing in my way of going forward with EF4/POCO in our system. I've found several articles and blogs touching upon these subjects, but for the life of me, I cannot resolve this issue. Feel free to simply ask questions and help me brainstorm this situation. PS: For the sake of being thorough, I am injecting the WCF services using the HEAD build of Spring.NET for the fix to Spring.ServiceModel.Activation.ServiceHostFactory. However I don't think this is the source of the problem.

  I am having a strange issue that I can't seem to resolve. Here is what happend: I had some log files in a github repository that I didn't want there. I found this script that removes files completely from git history like so: #!/bin/bash set -o errexit # Author: David Underhill # Script to permanently delete files/folders from your git repository. To use # it, cd to your repository's root and then run the script with a list of paths # you want to delete, e.g., git-delete-history path1 path2 if [ $# -eq 0 ]; then exit 0are still fi # make sure we're at the root of git repo if [ ! -d .git ]; then echo "Error: must run this script from the root of a git repository" exit 1 fi # remove all paths passed as arguments from the history of the repo files=$@ git filter-branch --index-filter "git rm -rf --cached --ignore-unmatch $files" HEAD # remove the temporary history git-filter-branch otherwise leaves behind for a long time rm -rf .git/refs/original/ && git reflog expire --all && git gc --aggressive --prune I, of course, made a backup first and then tried it. It seemed to work fine. I then did a git push -f and was greeted with the following messages: error: Unable to append to .git/logs/refs/remotes/origin/master: Permission denied error: Cannot update the ref 'refs/remotes/origin/master'. Everything seems to have pushed fine though, because the files seem to be gone from the GitHub repository, if I try and push again I get the same thing: error: Unable to append to .git/logs/refs/remotes/origin/master: Permission denied error: Cannot update the ref 'refs/remotes/origin/master'. Everything up-to-date EDIT $ sudo chgrp {user} .git/logs/refs/remotes/origin/master $ sudo chown {user} .git/logs/refs/remotes/origin/master $ git push Everything up-to-date Thanks! EDIT Uh Oh. Problem. I've been working on this project all night and just went to commit my changes: error: Unable to append to .git/logs/refs/heads/master: Permission denied fatal: cannot update HEAD ref So I: sudo chown {user} .git/logs/refs/heads/master sudo chgrp {user} .git/logs/refs/heads/master I try the commit again and I get: error: Unable to append to .git/logs/HEAD: Permission denied fatal: cannot update HEAD ref So I: sudo chown {user} .git/logs/HEAD sudo chgrp {user} .git/logs/HEAD And then I try the commit again: 16 files changed, 499 insertions(+), 284 deletions(-) create mode 100644 logs/DBerrors.xsl delete mode 100644 logs/emptyPHPerrors.php create mode 100644 logs/trimXMLerrors.php rewrite public/codeCore/Classes/php/DatabaseConnection.php (77%) create mode 100644 public/codeSite/php/init.php $ git push Counting objects: 49, done.

I've never had this issue before, could this be a problem with github? or did I mess something up with my git project? EDIT Nevermind, I did a simple: git push origin master and it pushed fine.

• OpenVPN Error : TLS Error: local/remote TLS keys are out of sync: [AF_INET]

  - by Lucidity

  Fist off thanks for reading this, I appreciate any and all suggestions. I am having some serious problems reconnecting to my OpenVPN client using Riseup.net's VPN. I have spent a few days banging my head against the wall in attempts to set this up on my iOS devices....but that is a whole other issue. I was however able to set it up on my Mac OS X specifically on my Windows Vista 32 bit BootCamp VM with relatively little trouble. To originally connect I only had to modify the recommended Config file very slightly (Config file included at the end of this post): - I had to enter the code directly into my config file - And change "dev tap" to "dev tun" So I was connected. (Note - I did test to ensure the VPN was actually working after I originally connected, it was. Also verified the .pem file (inserted as the coding in my config file) for authenticity). I left the VPN running. My computer went to sleep. Today I went to use the internet expecting (possibly incorrectly - I am now unsure if I was wrong to leave it running) to still be connected to the VPN. However I saw immediately I was not. I went to reconnect. And was (am) unable to. My logs after attempting to connect (and getting a connection failed dialog box) show everything working as it should (as far as I can tell) until the end where I get the following lines: Mon Sep 23 21:07:49 2013 us=276809 Initialization Sequence Completed Mon Sep 23 21:07:49 2013 us=276809 MANAGEMENT: >STATE:1379995669,CONNECTED,SUCCESS, OMITTED Mon Sep 23 21:22:50 2013 us=390350 Authenticate/Decrypt packet error: packet HMAC authentication failed Mon Sep 23 21:23:39 2013 us=862180 TLS Error: local/remote TLS keys are out of sync: [AF_INET] VPN IP OMITTED [2] Mon Sep 23 21:23:57 2013 us=395183 Authenticate/Decrypt packet error: packet HMAC authentication failed Mon Sep 23 22:07:41 2013 us=296898 TLS: soft reset sec=0 bytes=513834601/0 pkts=708032/0 Mon Sep 23 22:07:41 2013 us=671299 VERIFY OK: depth=1, C=US, O=Riseup Networks, L=Seattle, ST=WA, CN=Riseup Networks, [email protected] Mon Sep 23 22:07:41 2013 us=671299 VERIFY OK: depth=0, C=US, O=Riseup Networks, L=Seattle, ST=WA, CN=vpn.riseup.net Mon Sep 23 22:07:46 2013 us=772508 Data Channel Encrypt: Cipher 'BF-CBC' initialized with 128 bit key Mon Sep 23 22:07:46 2013 us=772508 Data Channel Encrypt: Using 160 bit message hash 'SHA1' for HMAC authentication Mon Sep 23 22:07:46 2013 us=772508 Data Channel Decrypt: Cipher 'BF-CBC' initialized with 128 bit key Mon Sep 23 22:07:46 2013 us=772508 Data Channel Decrypt: Using 160 bit message hash 'SHA1' for HMAC authentication Mon Sep 23 22:07:46 2013 us=772508 Control Channel: TLSv1, cipher TLSv1/SSLv3 DHE-RSA-AES256-SHA, 2048 bit RSA So I have searched for a solution online and I have included what I have attempted below, however I fear (know) I am not knowledgeable enough in this area to fix this myself. I apologize in advance for my ignorance. I do tech support for a living, but not this kind of tech support unfortunately. Other notes and troubleshooting done - - Windows Firewall is disabled completely, as well as other Anti-virus programs - Tor is disabled completely - No Proxies running - Time is correct in all locations - Router Firmware is up to date - Able to connect to the internet and as far as I can tell all necessary ports are open. - No settings have been altered since I was able to connect successfully. - Ethernet as well as wifi connections attempted, resulted in same error. Also tried adding the following lines to my config file (without success or change in error): persist-key persist-tun proto tcp (after reading that this error generally occurs on UDP connections, and is extremely rare on TCP) resolv-retry infinite (thinking the connection may have timed out since the issues occurred after leaving VPN connected during about 10 hrs of computer in sleep mode) All attempts resulted in exact same error code included at the top of this post. The original suggestions I found online stated - (regarding the TLS Error) - This error should resolve itself within 60 seconds, or if not quit wait 120 seconds and try again. (Which isnt the case here...) (regarding the Out of Sync" error) - If you continue to get "out of sync" errors and the link does not come up, then it means that something is probably wrong with your config file. You must use either ping and ping-restart on both sides of the connection, or keepalive on the server side of a client/server connection, in order to gracefully recover from "local/remote TLS keys are out of sync" errors. I wouldn't be surprised if my config file is lacking, or not correct. However I can confirm I followed the instructions to a tee. And was able to connect originally (and have not modified my settings or config file since I was able to connect to when the error began occurring). I have a very simple config file: client dev tun tun-mtu 1500 remote vpn.riseup.net auth-user-pass ca RiseupCA.pem redirect-gateway verb 4 <ca> -----BEGIN CERTIFICATE----- [OMITTED] -----END CERTIFICATE----- </ca> I would really appreciate any help or suggestions. I am at a total loss here, I know I'm asking a lot here. Though I am a new user on this site I help others on many forums including Microsoft's support community and especially Apple's support communities, so I will definitely pass on anything I learn here to help others. Thanks so so so much in advance for reading this.

• C# XmlSchemaSet - Resolving included schemas to enumerate attribute groups

  - by satixx

  Hi, I currently have a compiled XmlSchemaSet from which I get possible elements/attributes for each specific "parent" element defined in the schema. I have a single "master" xsd schema which includes another schema and uses attributeGroup references for some "common" elements. Here is a sample: (MasterSchema.xsd) <?xml version="1.0" encoding="utf-8"?> <xs:schema id="MasterSchema" xmlns:xs="http://www.w3.org/2001/XMLSchema" targetNamespace="CommonNamespace.xsd" xmlns="CommonNamespace.xsd" xmlns:mstns="CommonNamespace.xsd" elementFormDefault="qualified" > <xs:include schemaLocation="SourceAttributeGroups.xsd"/> <xs:element name="Binding" minOccurs="0" maxOccurs="2"> <xs:complexType> <xs:attribute name="Name" type="xs:string"/> <xs:attributeGroup ref="BindingSourceAttributeGroup"/> </xs:complexType> </xs:element> </xs:schema> (SourceAttributeGroups.xsd) <?xml version="1.0" encoding="utf-8"?> <xs:schema id="SourceAttributeGroups" xmlns:xs="http://www.w3.org/2001/XMLSchema" targetNamespace="CommonNamespace.xsd" xmlns="CommonNamespace.xsd" xmlns:mstns="CommonNamespace.xsd" elementFormDefault="qualified" > <xs:attributeGroup id="BindingSourceAttributeGroup" name="BindingSourceAttributeGroup"> <xs:attribute name="Source"> <xs:simpleType> <xs:restriction base="xs:string"> <xs:enumeration value="Data"/> </xs:restriction> </xs:simpleType> </xs:attribute> <!-- When Source is None --> <xs:attribute name="Value" type="xs:string"/> <!-- Label --> <xs:attribute name="Label" type="xs:string"/> </attributeGroup> </xs:schema> I would like to create an XmlSchemaSet in C# which would resolve, compile and "merge" every references of the MasterSchema so it would finaly look like this: (MasterSchema.xsd) <?xml version="1.0" encoding="utf-8"?> <xs:schema id="MasterSchema" xmlns:xs="http://www.w3.org/2001/XMLSchema" targetNamespace="CommonNamespace.xsd" xmlns="CommonNamespace.xsd" xmlns:mstns="CommonNamespace.xsd" elementFormDefault="qualified" > <xs:include schemaLocation="SourceAttributeGroups.xsd"/> <xs:element name="Binding" minOccurs="0" maxOccurs="2"> <xs:complexType> <xs:attribute name="Name" type="xs:string"/> <xs:attribute name="Source"> <xs:simpleType> <xs:restriction base="xs:string"> <xs:enumeration value="Data"/> </xs:restriction> </xs:simpleType> </xs:attribute> <!-- When Source is None --> <xs:attribute name="Value" type="xs:string"/> <!-- Label --> <xs:attribute name="Label" type="xs:string"/> </xs:complexType> </xs:element> </xs:schema> This way, I could traverse each XmlSchemaParticle of the compiled schema to get every single attribute for a specific element, even when its attributes are defined in an external schema. At the moment, when I get the possible attributes for a "Binding" element, I only get the "Name" attribute since it is originally defined in the "master" schema. What would be the possible solutions to this problem? Thanks! Satixx
