How to setup Dual Head with "radeon" driver for R770?

- by user1709408

I want to make dual head setup without xrandr but with Xinerama. I put "Screen 1" line into xorg.conf, but card still show identical output on DVI-2 and DVI-3 It is important to use xinerama for me (to glue three monitors), that's why i decide not to use ranrd (randr is incompatible with xinerama as i read somewhere) Here is my videocard (HD 4850 X2): lspci | grep R700 03:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI R700 [Radeon HD 4850] 04:00.0 Display controller: Advanced Micro Devices [AMD] nee ATI R700 [Radeon HD 4850] Here is how monitors are connected: grep "DVI" /var/log/Xorg.0.log [ 1210.002] (II) RADEON(0): Output DVI-0 using monitor section Monitor0 [ 1210.048] (II) RADEON(0): Output DVI-1 has no monitor section [ 1210.079] (II) RADEON(0): EDID for output DVI-0 [ 1210.080] (II) RADEON(0): Printing probed modes for output DVI-0 [ 1210.128] (II) RADEON(0): EDID for output DVI-1 [ 1210.128] (II) RADEON(0): Output DVI-0 connected [ 1210.128] (II) RADEON(0): Output DVI-1 disconnected [ 1210.128] (II) RADEON(0): Output DVI-0 using initial mode 1920x1200 [ 1210.160] (II) RADEON(1): Output DVI-2 using monitor section Monitor2 [ 1210.215] (II) RADEON(1): Output DVI-3 has no monitor section [ 1210.246] (II) RADEON(1): EDID for output DVI-2 [ 1210.247] (II) RADEON(1): Printing probed modes for output DVI-2 [ 1210.299] (II) RADEON(1): EDID for output DVI-3 [ 1210.300] (II) RADEON(1): Printing probed modes for output DVI-3 [ 1210.300] (II) RADEON(1): Output DVI-2 connected [ 1210.300] (II) RADEON(1): Output DVI-3 connected [ 1210.300] (II) RADEON(1): Output DVI-2 using initial mode 1920x1200 [ 1210.300] (II) RADEON(1): Output DVI-3 using initial mode 1920x1200 Here is my /etc/X11/xorg.conf Section "ServerFlags" Option "RandR" "0" Option "Xinerama" "1" EndSection Section "ServerLayout" Identifier "Three Head Layout" Screen "MyPrecious0" Screen "MyPrecious2" RightOf "MyPrecious0" Screen "MyPrecious3" LeftOf "MyPrecious0" EndSection Section "Screen" Identifier "MyPrecious0" Monitor "Monitor0" Device "Device300" EndSection Section "Screen" Identifier "MyPrecious2" Monitor "Monitor2" Device "Device400" EndSection Section "Screen" Identifier "MyPrecious3" Monitor "Monitor3" Device "Device401" EndSection Section "Device" Identifier "Device300" BusID "PCI:3:0:0" Screen 0 Driver "radeon" EndSection Section "Device" Identifier "Device400" BusID "PCI:4:0:0" Screen 0 Driver "radeon" EndSection Section "Device" Identifier "Device401" BusID "PCI:4:0:0" Screen 1 Driver "radeon" EndSection Section "Monitor" Identifier "Monitor0" EndSection Section "Monitor" Identifier "Monitor2" EndSection Section "Monitor" Identifier "Monitor3" EndSection I tried to switch to vesa driver (didn't work for me) I tried to add options like Option "ZaphodHeads" "DVI-2" and Option "ZaphodHeads" "DVI-3" into sections "Device 400" and "Device 401" (this didn't help because "ZaphodHeads" option is for ranrd, and randr is disabled by decision) I tried to merge sections "Device 400" and "Device 401" into one section and add Option "ZaphodHeads" "DVI-2,DVI-3" (see comment about randr above) single section setup helps to change log line RADEON(1): Output DVI-3 has no monitor section into RADEON(1): Output DVI-3 using monitor section Monitor3 but nothing was enough to switch from screen cloning to separate screens. This problem (lack of documentation on radeon driver) is similar to these: Radeon display driver clones monitors while using Xinerama (moderators decision to close that problem was wrong) Ubuntu 12.10 multi-monitor setup isn't working The problem is solvable, because this hardware worked as three headed for me earlier with gentoo/xorg-server-1.3 Xorg -configure creates setup for the first monitor on the first GPU Please don't advise to use fglrx/aticonfig/amdcccle (this goes against my religion beliefs)

Windows Azure End to End Examples

- by BuckWoody

I’m fascinated by the way people learn. I’m told there are several methods people use to understand new information, from reading to watching, from experiencing to exploring. Personally, I use multiple methods of learning when I encounter a new topic, usually starting with reading a bit about the concepts. I quickly want to put those into practice, however, especially in the technical realm. I immediately look for examples where I can start trying out the concepts. But I often want a “real” example – not just something that represents the concept, but something that is real-world, showing some feature I could actually use. And it’s no different with the Windows Azure platform – I like finding things I can do now, and actually use. So when I started learning Windows Azure, I of course began with the Windows Azure Training Kit – which has lots of examples and labs, presentations and so on. But from there, I wanted more examples I could learn from, and eventually teach others with. I was asked if I would write a few of those up, so here are the ones I use. CodePlex CodePlex is Microsoft’s version of an “Open Source” repository. Anyone can start a project, add code, documentation and more to it and make it available to the world, free of charge, using various licenses as they wish. Microsoft also uses this location for most of the examples we publish, and sample databases for SQL Server. If you search in CodePlex for “Azure”, you’ll come back with a list of projects that folks have posted, including those of us at Microsoft. The source code and documentation are there, so you can learn using actual examples of code that will do what you need. There’s everything from a simple table query to a full project that is sort of a “Corporate Dropbox” that uses Windows Azure Storage. The advantage is that this code is immediately usable. It’s searchable, and you can often find a complete solution to meet your needs. The disadvantage is that the code is pretty specific – it may not cover a huge project like you’re looking for. Also, depending on the author(s), you might not find the documentation level you want. Link: http://azureexamples.codeplex.com/site/search?query=Azure&ac=8 Tailspin Microsoft Patterns and Practices is a group here that does an amazing job at sharing standard ways of doing IT – from operations to coding. If you’re not familiar with this resource, make sure you read up on it. Long before I joined Microsoft I used their work in my daily job – saved a ton of time. It has resources not only for Windows Azure but other Microsoft software as well. The Patterns and Practices group also publishes full books – you can buy these, but many are also online for free. There’s an end-to-end example for Windows Azure using a company called “Tailspin”, and the work covers not only the code but the design of the full solution. If you really want to understand the thought that goes into a Platform-as-a-Service solution, this is an excellent resource. The advantages are that this is a book, it’s complete, and it includes a discussion of design decisions. The disadvantage is that it’s a little over a year old – and in “Cloud” years that’s a lot. So many things have changed, improved, and have been added that you need to treat this as a resource, but not the only one. Still, highly recommended. Link: http://msdn.microsoft.com/en-us/library/ff728592.aspx Azure Stock Trader Sometimes you need a mix of a CodePlex-style application, and a little more detail on how it was put together. And it would be great if you could actually play with the completed application, to see how it really functions on the actual platform. That’s the Azure Stock Trader application. There’s a place where you can read about the application, and then it’s been published to Windows Azure – the production platform – and you can use it, explore, and see how it performs. I use this application all the time to demonstrate Windows Azure, or a particular part of Windows Azure. The advantage is that this is an end-to-end application, and online as well. The disadvantage is that it takes a bit of self-learning to work through. Links: Learn it: http://msdn.microsoft.com/en-us/netframework/bb499684 Use it: https://azurestocktrader.cloudapp.net/

Book review: Microsoft System Center Enterprise Suite Unleashed

- by BuckWoody

I know, I know – what’s a database guy doing reading a book on System Center? Well, I need it from time to time. System Center is actually a collection of about 7 different products that you can use to manage and monitor your software and hardware, from drive space through Microsoft Office, UNIX systems, and yes, SQL Server. It’s that last part I care about the most, and so I’ve dealt with Data Protection Manager and System Center Operations Manager (I call it SCOM) in SQL Server. But I wasn’t familiar with the rest of the suite nor was I as familiar as I needed to be with the “Essentials” release – a separate product that groups together the main features of System Center into a single offering for smaller organizations. These companies usually run with a smaller IT shop, so they sometimes opt for this product to help them monitor everything, including SQL Server. So I picked up “Microsoft System Center Enterprise Suite Unleashed” by Chris Amaris and a cast of others. I don’t normally like to get a technical book by multiple authors – I just find that most of the time it’s quite jarring to switch from author to author, but I think this group did pretty well here. The first chapter on introducing System Center has helped me talk with others about what the product does, and which pieces fit well together with SQL Server. The writing is well done, and I didn’t find a jump from author to author as I went along. The information is sequential, meaning that they lead you from install to configuration and then use. It’s very much a concepts-and-how-to book, and a big one at that – over 950 pages of learning! It was a pretty quick read, though, since I skipped the installation parts and there are lots of screenshots. While I’m not sure you’d be an expert on the product when you finish reading this book, but I would say you’re more than halfway there. I would say it suits someone that learns through examples the best, since they have a lot of step-by-step examples I do recommend that you take a look if you have to interact with this product, or even if you are a smaller shop and you’re the primary IT resource. The last few chapters deal with System Center Essentials, and honestly it was the best part of the book for me. Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

What Did You Do? is a Bad Question

- by Ajarn Mark Caldwell

Brian Moran (blog | Twitter) did a great presentation today for the PASS Professional Development Virtual Chapter on The Art of Questions. One of the points that Brian made was that there are good questions and bad (or at least not-as-good) questions. Good questions tend to open-up the conversation and engender positive reactions (perhaps even trust and respect) between the participants; and bad questions tend to close-down a conversation either through the narrow list of possible responses (e.g. strictly Yes/No) or through the negative reactions they can produce. And this explains why I so frequently had problems troubleshooting real-time problems with users in the past. I’ll explain that in more detail below, but before we go on, let me recommend that you watch the recording of Brian’s presentation to learn why the question Why is often problematic in the U.S. and yet we so often resort to it. For a short portion (3 years) of my career, I taught basic computer skills and Office applications in an adult vocational school, and this gave me ample opportunity to do live troubleshooting of user challenges with computers. And like many people who ended up in computer related jobs, I also have had numerous times where I was called upon by less computer-savvy individuals to help them with some challenge they were having, whether it was part of my job or not. One of the things that I noticed, especially during my time as a teacher, was that when I was helping somebody, typically the first question I would ask them was, “What did you do?” This seemed to me like a good way to start my detective work trying to figure out what happened, what went wrong, how to fix it, and how to help the person avoid it again in the future. I always asked it in a polite tone of voice as I was just trying to gather the facts before diving in deeper. However; 99.999% of the time, I always got the same answer, “Nothing!” For a long time this frustrated me because (remember I’m in detective mode at that point) I knew it could not possibly be true. They HAD to have done SOMETHING…just tell me what were the last actions you took before this problem presented itself. But no, they always stuck with “Nothing”. At which point, with frustration growing, and not a little bit of disdain for their lack of helpfulness, I would usually ask them to move aside while I took over their machine and got them out of whatever they had gotten themselves into. After a while I just grew used to the fact that this was the answer I would usually receive, but I always kept asking because for the .001% of the people who would actually tell me, I could then help them understand what went wrong and how to avoid it in the future. Now, after hearing Brian’s talk, I understand what the problem was. Even though I meant to just be in an information gathering mode, the words I was using, “What did YOU do?” have such a strong negative connotation that people would instinctively go into defense-mode and stop sharing information that might make them look bad. Many of them probably were not even consciously aware that they had gone on the defensive, but the self-preservation instinct, especially self-preservation of the ego, is so strong that people would end up there without even realizing it. So, if “What did you do” is a bad question, what would have been better? Well, one suggestion that Brian makes in his talk is something along the lines of, “Can you tell me what led up to this?” or “what was happening on the computer right before this came up?” It’s subtle, but the point is to take the focus off of the person and their behavior; instead depersonalizing it and talk about events from more of a 3rd-party observer point of view. With this approach, people will be more likely to talk about what the computer did and what they did in response to it without feeling the interrogation spotlight is on them. They are also more likely to mention other events that occurred around the same time that may or may not be related, but which could certainly help you troubleshoot a larger problem if it is not just user actions. And that is the ultimate goal of your asking the questions. So yes, it does matter how you ask the question; and there are such things as good questions and bad questions. Excellent topic Brian! Thanks for getting the thinking gears churning! (Cross-posted to the Professional Development Virtual Chapter blog.)

Create Orchard Module in a Separate Project

- by Steve Michelotti

The Orchard Project is a new OOS Microsoft project that is being developed up on CodePlex. From the Orchard home page on CodePlex, it states “Orchard project is focused on delivering a .NET-based CMS application that will allow users to rapidly create content-driven Websites, and an extensibility framework that will allow developers and customizers to provide additional functionality through modules and themes.” The Orchard Project site contains additional information including documentation and walkthroughs. The ability to create a composite solution based on a collection of modules is a compelling feature. In Orchard, these modules can just be created as simple MVC Areas or they can also be created inside of stand-alone web application projects. The walkthrough for writing an Orchard module that is available on the Orchard site uses a simple Area that is created inside of the host application. It is based on the Orchard MIX presentation. This walkthrough does an effective job introducing various Orchard concepts such as hooking into the navigation system, theme/layout system, content types, and more. However, creating an Orchard module in a separate project does not seem to be concisely documented anywhere. Orchard ships with several module OOTB that are in separate assemblies – but again, it’s not well documented how to get started building one from scratch. The following are the steps I took to successfully get an Orchard module in a separate project up and running. Step 1 – Download the OrchardIIS.zip file from the Orchard Release page. Unzip and open up the solution. Step 2 – Add your project to the solution. I named my project “Orchard.Widget” and used and “MVC 2 Empty Web Application” project type. Make sure you put the physical path inside the “Modules” sub-folder to the main project like this: At this point the solution should look like: Step 3 – Add assembly references to Orchard.dll and Orchard.Core.dll. Step 4 – Add a controller and view. I’ll just create a Hello World controller and view. Notice I created the view as a partial view (*.ascx). Also add the [Themed] attribute to the top of the HomeController class just like the normal Orchard walk through shows it. Step 5 – Add Module.txt to the project root. The is a very important step. Orchard will not recognize your module without this text file present. It can contain just the name of your module: name: Widget Step 6 – Add Routes.cs. Notice I’ve given an area name of “Orchard.Widget” on lines 26 and 33. 1: using System; 2: using System.Collections.Generic; 3: using System.Web.Mvc; 4: using System.Web.Routing; 5: using Orchard.Mvc.Routes; 6: 7: namespace Orchard.Widget 8: { 9: public class Routes : IRouteProvider 10: { 11: public void GetRoutes(ICollection<RouteDescriptor> routes) 12: { 13: foreach (var routeDescriptor in GetRoutes()) 14: { 15: routes.Add(routeDescriptor); 16: } 17: } 18: 19: public IEnumerable<RouteDescriptor> GetRoutes() 20: { 21: return new[] { 22: new RouteDescriptor { 23: Route = new Route( 24: "Widget/{controller}/{action}/{id}", 25: new RouteValueDictionary { 26: {"area", "Orchard.Widget"}, 27: {"controller", "Home"}, 28: {"action", "Index"}, 29: {"id", ""} 30: }, 31: new RouteValueDictionary(), 32: new RouteValueDictionary { 33: {"area", "Orchard.Widget"} 34: }, 35: new MvcRouteHandler()) 36: } 37: }; 38: } 39: } 40: } Step 7 – Add MainMenu.cs. This will make sure that an item appears in the main menu called “Widget” which points to the module. 1: using System; 2: using Orchard.UI.Navigation; 3: 4: namespace Orchard.Widget 5: { 6: public class MainMenu : INavigationProvider 7: { 8: public void GetNavigation(NavigationBuilder builder) 9: { 10: builder.Add(menu => menu.Add("Widget", item => item.Action("Index", "Home", new 11: { 12: area = "Orchard.Widget" 13: }))); 14: } 15: 16: public string MenuName 17: { 18: get { return "main"; } 19: } 20: } 21: } Step 8 – Clean up web.config. By default Visual Studio adds numerous sections to the web.config. The sections that can be removed are: appSettings, connectionStrings, authentication, membership, profile, and roleManager. Step 9 – Delete Global.asax. This project will ultimately be running from inside the Orchard host so this “sub-site” should not have its own Global.asax. Now you’re ready the run the app. When you first run it, the “Widget” menu item will appear in the main menu because of the MainMenu.cs file we added: We can then click the “Widget” link in the main menu to send us over to our view: Packaging From start to finish, it’s a relatively painless experience but it could be better. For example, a Visual Studio project template that encapsulates aspects from this blog post would definitely make it a lot easier to get up and running with creating an Orchard module. Another aspect I found interesting is that if you read the first paragraph of the walkthrough, it says, “You can also develop modules as separate projects, to be packaged and shared with other users of Orchard CMS (the packaging story is still to be defined, along with marketplaces for sharing modules).” In particular, I will be extremely curious to see how the “packaging story” evolves. The first thing that comes to mind for me is: what if we explored MvcContrib Portable Areas as a potential mechanism for this packaging? This would certainly make things easy since all artifacts (aspx, aspx, images, css, javascript) are all wrapped up into a single assembly. Granted, Orchard does have its own infrastructure for layouts and themes but it seems like integrating portable areas into this pipeline would not be a difficult undertaking. Maybe that’ll be the next research task. :)

The validation process certifies that the journal entries are accurate, ensuring that ChartFields values are valid, debits and credits equal out, and inter/intra-units are balanced. Once validated, the entries are processed, ensuring that each journal line posts to the correct target ledger, and then changes the journal status to posted. In this benchmark, the Journal Edit & Post is set up to edit and post both Inter-Unit and Regular multi-currency journals. The benchmark processes 20 million journal lines using AppEngine for edits and Cobol for post processes.

Antenna Aligner Part 10: Updates and emails…

- by Chris George

Since my last post back in July, I’ve not done huge amounts of work on my app for two reasons. Firstly, no time! Secondly, I wanted to leave it out in the wild for a while and see what happened. Well, what happened? over 1,300 users, that’s what’s happened! This uptake is beyond my wildest expectations, and apart from a couple of issues that I’ll mention in a minute, most of the feedback has been very positive indeed! I’ve had several emails giving me feedback and reporting issues, all of which I have made a point of replying to immediately. This act alone has met with favourable replies! One of the main issues was with iPad. So it turns out that my app is only accurate in portrait mode. Turning it into landscape will offset the direction by +-90degrees! Whoops! I think I’ve fixed this by disabling the orientation switching, but I have not yet had an iPad to test this on. I had several emails from iPod Touch users claiming the app did not work for them. Specifically, the compass view did not work. On investigation, it turns out that the iPod Touch does not have the compass hardware required to do this. Unfortunately there is no way to exclude iPod Touch’s from the list of supported devices, so I’ve just had to make it very clear in the itunes description that the device is not fully supported. You can still get the list of transmitters, but you then have to use a real compass to get the bearing. But that’s not the end of the world. Several customers have requested the aerial polarisation to be displayed in the app. I was already working on this, and the data was already there, it was just a case of displaying this in the UI. I have a solution now, and this will be in the next release. Of course, with the Digital switchover in full swing across the UK, there have been one set of data updates (in 1.0.3), and another is due shortly. This reflects the transmitters as they switch over the digital fully and their power output increased. So all in all I’m very pleased with the feedback I’ve had, and I’m looking to get the next release out there by early December (allowing for the 2-3 week Apple approval lag!)

The Jack LaLanne School of Sysadmins

- by rickramsey

Two of my childhood heroes were Tarzan and Jack LaLanne. Tarzan was an obvious choice: what boy wouldn't want to spend his days bungee jumping through the jungle with his own pack of gorillas? Jack Lalanne had a disturbing habit of wearing stretch pants, but he was so damn fit for an old guy that you couldn't help but be impressed. Especially back then, when nobody knew what a dumb bell was, much less Cross-Fit. Here's what he did to celebrate his 70th birthday. Sooner or later we all face a choice in our careers: surrender to the life of a has-been like Bruce Sprinsteen's baseball player or become an unstoppable sysadmin like Jack Lalanne. If you'd rather keep on fighting like Jack, give these resources a look. Brian Bream's blog provides specific suggestions for keeping your skills up to date. The video interviews describe the types of technologies that are challenging what you used to know. Blog: The Old School Sysadmin - A Dying Breed? by Brian Bream "The sysadmin role has been far too dependent on performing repetitive tasks and working in a reactionary mode ... the sysadmin must grow a much larger skill set to be successful. Don’t grow vertically in one technology, grow horizontally amongst many technologies." Just one of the suggestions Brian Bream provides in this excellent blog post. Video: Freeing the Sysadmin From Repetitive Tasks Interview with Marshall Choy Marshall Choy, Director of Optimized Solutions at Oracle was once a sysadmin. And a Solaris engineer. He explains what optimized solutions are, how they are developed and tested, how they handle patching, and how these vertically integrated systems impact the job and duties of a sysadmin. Video: The Oracle Database Appliance Interview with Bob Thome Bob Thome, Senior Director of Product Management, explains what makes the Database Appliance simple, reliable, and affordable, and how it could change the economies and processes of the data center. Video: Why Pinellas County Chose Oracle Exalytics Interview with Gautham Gautham (pronounced like Batman's Gotham) recently led an effort to refresh the Pinellas County hardware systems. He'll explain what they were looking for, why they chose Oracle Exalytics, how they became convinced it was the right decision, and how it changed the way they managed their data center. Video: DTrace for System Administrators Interview with Brendan Gregg This video interview will give you an idea of some of the value-add tasks you can perform when you are freed from the reactive mode that Brian Bream describes in his blog.

Download Internet Explorer 9 RTM

- by Harish Ranganathan

The much anticipated RTM release of Internet Explorer 9 (IE9) happened today. IE9 preview release was first showcased at MIX 2010 and post that there were 7-8 Platform Preview releases. Also, IE9 Beta came out in September 2010 with close to 10 million downloads within a month. More recently, the RC version was out with much improved performance. Today, marks the launch of IE9 RTM. What this means is that, within an year, the IE Team has shipped the stable product, much faster than the earlier cycles for IE8 and IE7. I wanted to clarify a few things (myths) that arise in common 1. I am already using Chrome and its faster for me, why would I need IE9 IE9 uses 100% hardware acceleration which means, you are going to get the best of performance compared to any other browser that shipped/will ship in future. With native Windows support, IE9 will outperform all other browsers in terms of performance. 2. What about standards and security Agreed IE6 hasn’t been in the best of standards, but why would someone compare IE6 which was released almost 10 years back. Later, we shipped IE7 and IE8 which had the best of standards and supports during their timeframes, but one would agree that standards and specifications keep getting updated and its hard to keep pace with the same for older browsers. Example. HTML5 support is not there in IE8 but it is very much there in IE9. IE9 supports most of the stable standards of HTML5 and its going to provide preview releases for the work-in-progress standards. 3. IE doesn’t keep in pace with other browsers Agreed! we don’t force/release updates on major versions in very short time periods. What we do is provide Windows Update that provides security updates/patches and other critical updates for not just IE but the whole of Windows operating system 4. I am running Windows XP, what do I do? This is the trickiest part. Windows XP isn’t the supported operating system for IE9 and there are various reasons to it. The recommended operating system is Windows Vista and Windows 7. In the interest of technology and its pace, we had to discontinue Windows XP both from a retail selling perspective as well as IE9 support. But, the recent 2 years has seen PCs/Laptops only shipped with Windows Vista or Windows 7 so, it shouldn't affect them. 5. Where do I verify IE9’s performance/standard support and other information. http://samples.msdn.microsoft.com/ietestcenter/ Here below is a snapshot of one of the tests. Clearly IE9 outperforms all other browsers and will continue to outperform them in future. You can download IE9 from www.beautyoftheweb.com Cheers!!!

Live CD / Live USB much faster than full install

- by user29347

I've observed it on both laptops I own! HP Compaq nx6125 and Ubuntu 11.04 x64 - somewhat solved Lenovo Thinkpad T500 and Ubuntu 11.10 x64 - help needed! I'm still struggling with the Thinkpad to get performance level similar to that of 10 y.o. laptops... All in all a really serious issue with multiple versions of Ubuntu that renders computers with perfectly compatible hardware unusable, as far as out of the box experience is concerned. Troubleshooting resultant issues seems to be a hard case even for users with some experience with installing graphics drivers. EDIT: I can't really post additional details. Two different ubuntu versions, two laptops, two different set of graph. drivers (OS vs ATI prop.) - all with the same symptoms. Also I can't stress enough how massive the performance degradation is compared to a healthy system. For that reason I ask for input from people who may know roughly what are we dealing with here. I can post more details if we were to focus on my current Thinkpad T500. In that case my current system details: Lenovo Thinkpad T500 Ubuntu 11.10 x64 ATI Mobility Radeon HD 3650 (also see the "What I have already tried" section about Intel graphics tested) ATI Catalyst 11.10 drivers OCZ Agility 3 SSD but! same with the default driver for ATI the card same with the prop. driver for the ATI card from Jockey (Additional drivers applet) What I have already tried: 0. Switching to Intel integrated card (Intel GMA 4500M HD) with the default driver - same effects = may indicate not driver related problem but a problem with something of global influence like e.g. nomodeset or other I don't even know about. (What you can read above) ATI Catalyst 11.10 and radeon.modeset=0 boot parameter + disabled Wait for VBlank. Unity 2D Ubuntu 10.04 LTS tested (ubuntu-10.04.3-desktop-i386.iso): Both live USB and installed version blazing fast! (on the default drivers - without even installing the proprietary fglrx drivers). re2 a) seems to give me the only significant results (still poor) - perfect Unity elements performance with the same crawling stuttering/lagging when dragging windows around. re2 b) this happens often http://i17.photobucket.com/albums/b68/Bucic/ubuntuforumsorg/Screenshotat2011-10-28083140.png re2 c) Sometimes I am able to witness a normal performance when dragging a window around but only for a second or two. When I try to shake it longer it starts to lag and it will keep lagging like that with an increased probability of what you see in the sshot in point re2 b). re2 d) I can't establish the radeon.modeset=0 influence though. Once it seems to work be smooth with it, the other time - without it. Really can't tell.

VLC will sometimes have issues displaying video in fullscreen. What could cause this? How would I troubleshoot the issue?

- by George Marian

Recently VLC has been having issues displaying video in fullscreen mode. AFAIK, nothing has changed with the video card drivers and it's certainly the same version of VLC. (/me shakes a fist at the repository maintainers) This has worked without issue in the past. In fact, I've had as many as 6 instances of VLC running, each playing a video. One was always fullscreen on my second monitor, while the others were tiled on my primary monitor. I was able to toggle any of the other 5 into fullscreen mode and the video displayed without issue. Lately, I've been having trouble running 2 instances in fullscreen mode. (Sometimes, even a single instance will not display the video in fullscreen.) VLC will continue to play the video, but in fullscreen mode I see nothing but a black screen. Sometimes, the video will display if I maximize the VLC window. Other times, I have to settle for a smaller sized window. I don't know if this is pertinent, but sometimes changing the min/max state of a Firefox window (Minefield, specifically) seemed to allow the troublesome instance to display the video in fullscreen mode. However, that did not prove to be a consistent workaround. Sometimes, it seemed that closing a Firefox window did the trick, though that isn't consistently successful either. (I futzed with Firefox, because with the crazy number of windows and tabs that I normally have open, it regularly hogs about 1 GB of RAM.) Another bit of funkiness that comes to mind is the fact that my secondary monitor is considered the primary on boot-up. I use xrandr to designate the real 1st monitor as primary after boot-up, as suggested by someone in a question I asked on the Unix & Linux SE site. Specs: Ubuntu 10.10 w/ Gnome and Compiz 8GB RAM AMD Phenom II 965 Black Edition Asus M4A79 Deluxe mobo XFX ATI Radeon HD 5750 w/ 1GB RAM VLC is configured to use the hardware overlay for video (as per the default setting) Does anyone have an idea what may cause this issue or how I may go about troubleshooting it? Update: Right now I have 2 instances of VLC playing, each in fullscreen mode on a separate monitor. This is what I see:

The winning combination: Oracle VM Server for x86 + Oracle Sun Fire HW

- by Karim Berrah

You might be wondering why OVM Server for x86 (OVM/x86 here and below) should be seriously considered as a nice (business point of view) alternative to standard Hypervisors, if you are virtualizing Oracle Software, especially if you are planning to move to Oracle x86 Hardware (rackmount or blades). Well, let see some "not well known" facts that might interest you and help you in saving more money for your entire company (and not only the Virtulization team). Fact 1: OVM/x86 is considered as a hard partitionning technology (check page 2 of Oracle Server Partitionning Licencing Policies), so if you are buying new servers based on the latest INTEL Xeon E7 CPUs (10 cores per Socket) and have some licencing issues in deploying further Oracle SW, because you are using a hypervisor not recognized as a hard partitionning technology (like VMware), then you need to check here how to do it with OVM . This might help you to continue to deploy your Oracle DB instances on new x86 HW (12 cores, 40 cores, 64 cores servers) in a reasonable way, without having to pay licences for 12 CPU, 40 CPUs or 64 CPUs. You might also consider migrating your legacy Oracle DB DBs to a virtualized environment like OVM/x86 an recover some CPU licences, that can be reused somewhere else in production. Fact 2: OVM/x86 is free to use, without any extra licence for any specific feature (LiveMigration, High Availability, Embedded Management Console). If you want to use it on non Oracle HW, there is a support fee per system and per year, that is much below VMware support (Oracle VM Premier Limited Support for systems up to 2 CPUs, and Oracle VM Premier Support for any bigger system, independently on the number of populated sockets). Fact 3: support is included with your Oracle x86 HW support (OPS for systems) and you can re-install on you system Oracle Linux, Oracle Solaris or Oracle VM server for x86, without beeing charged, an keeping the same support level. Fact 4: it is less expensive to virtualize Oracle Linux or Oracle Solaris on OVM/x86 with Oracle HW that any other similar solution with VMware, because all the VMs are then supported and licenced when you buy Oracle HW with OPS. Fact 5: Oracle VM Templates bring you many Virtual Machines already installed, patched and optimized for various Oracle applications. And to be more specific, those templates are fully supported by Oracle, which is not really true when it comes to another hypervisor. By optimized VM Kernel, I mean PV drivers, OVM-ready kernels in the VM, single source clock for all the VMS, better memory management of the VM ... Fact 6: there is no extra costs for a management console. OVM comes with a free OVM Manager package for Linux.

Windows Azure End to End Examples

- by BuckWoody

I’m fascinated by the way people learn. I’m told there are several methods people use to understand new information, from reading to watching, from experiencing to exploring. Personally, I use multiple methods of learning when I encounter a new topic, usually starting with reading a bit about the concepts. I quickly want to put those into practice, however, especially in the technical realm. I immediately look for examples where I can start trying out the concepts. But I often want a “real” example – not just something that represents the concept, but something that is real-world, showing some feature I could actually use. And it’s no different with the Windows Azure platform – I like finding things I can do now, and actually use. So when I started learning Windows Azure, I of course began with the Windows Azure Training Kit – which has lots of examples and labs, presentations and so on. But from there, I wanted more examples I could learn from, and eventually teach others with. I was asked if I would write a few of those up, so here are the ones I use. CodePlex CodePlex is Microsoft’s version of an “Open Source” repository. Anyone can start a project, add code, documentation and more to it and make it available to the world, free of charge, using various licenses as they wish. Microsoft also uses this location for most of the examples we publish, and sample databases for SQL Server. If you search in CodePlex for “Azure”, you’ll come back with a list of projects that folks have posted, including those of us at Microsoft. The source code and documentation are there, so you can learn using actual examples of code that will do what you need. There’s everything from a simple table query to a full project that is sort of a “Corporate Dropbox” that uses Windows Azure Storage. The advantage is that this code is immediately usable. It’s searchable, and you can often find a complete solution to meet your needs. The disadvantage is that the code is pretty specific – it may not cover a huge project like you’re looking for. Also, depending on the author(s), you might not find the documentation level you want. Link: http://azureexamples.codeplex.com/site/search?query=Azure&ac=8 Tailspin Microsoft Patterns and Practices is a group here that does an amazing job at sharing standard ways of doing IT – from operations to coding. If you’re not familiar with this resource, make sure you read up on it. Long before I joined Microsoft I used their work in my daily job – saved a ton of time. It has resources not only for Windows Azure but other Microsoft software as well. The Patterns and Practices group also publishes full books – you can buy these, but many are also online for free. There’s an end-to-end example for Windows Azure using a company called “Tailspin”, and the work covers not only the code but the design of the full solution. If you really want to understand the thought that goes into a Platform-as-a-Service solution, this is an excellent resource. The advantages are that this is a book, it’s complete, and it includes a discussion of design decisions. The disadvantage is that it’s a little over a year old – and in “Cloud” years that’s a lot. So many things have changed, improved, and have been added that you need to treat this as a resource, but not the only one. Still, highly recommended. Link: http://msdn.microsoft.com/en-us/library/ff728592.aspx Azure Stock Trader Sometimes you need a mix of a CodePlex-style application, and a little more detail on how it was put together. And it would be great if you could actually play with the completed application, to see how it really functions on the actual platform. That’s the Azure Stock Trader application. There’s a place where you can read about the application, and then it’s been published to Windows Azure – the production platform – and you can use it, explore, and see how it performs. I use this application all the time to demonstrate Windows Azure, or a particular part of Windows Azure. The advantage is that this is an end-to-end application, and online as well. The disadvantage is that it takes a bit of self-learning to work through. Links: Learn it: http://msdn.microsoft.com/en-us/netframework/bb499684 Use it: https://azurestocktrader.cloudapp.net/

Oracle’s Sun Server X4-8 with Built-in Elastic Computing

- by kgee

We are excited to announce the release of Oracle's new 8-socket server, Sun Server X4-8. It’s the most flexible 8-socket x86 server Oracle has ever designed, and also the most powerful. Not only does it use the fastest Intel® Xeon® E7 v2 processors, but also its memory, I/O and storage subsystems are all designed for maximum performance and throughput. Like its predecessor, the Sun Server X4-8 uses a “glueless” design that allows for maximum performance for Oracle Database, while also reducing power consumption and improving reliability. The specs are pretty impressive. Sun Server X4-8 supports 120 cores (or 240 threads), 6 TB memory, 9.6 TB HDD capacity or 3.2 TB SSD capacity, contains 16 PCIe Gen 3 I/O expansion slots, and allows for up to 6.4 TB Sun Flash Accelerator F80 PCIe Cards. The Sun Server X4-8 is also the most dense x86 server with its 5U chassis, allowing 60% higher rack-level core and DIMM slot density than the competition. There has been a lot of innovation in Oracle’s x86 product line, but the latest and most significant is a capability called elastic computing. This new capability is built into each Sun Server X4-8. Elastic computing starts with the Intel processor. While Intel provides a wide range of processors each with a fixed combination of core count, operational frequency, and power consumption, customers have been forced to make tradeoffs when they select a particular processor. They have had to make educated guesses on which particular processor (core count/frequency/cache size) will be best suited for the workload they intend to execute on the server.Oracle and Intel worked jointly to define a new processor, the Intel Xeon E7-8895 v2 for the Sun Server X4-8, that has unique characteristics and effectively combines the capabilities of three different Xeon processors into a single processor. Oracle system design engineers worked closely with Oracle’s operating system development teams to achieve the ability to vary the core count and operating frequency of the Xeon E7-8895 v2 processor with time without the need for a system level reboot. Along with the new processor, enhancements have been made to the system BIOS, Oracle Solaris, and Oracle Linux, which allow the processors in the system to dynamically clock up to faster speeds as cores are disabled and to reach higher maximum turbo frequencies for the remaining active cores. One customer, a stock market trading company, will take advantage of the elastic computing capability of Sun Server X4-8 by repurposing servers between daytime stock trading activity and nighttime stock portfolio processing, daily, to achieve maximum performance of each workload.To learn more about Sun Server X4-8, you can find more details including the data sheet and white papers here.Josh Rosen is a Principal Product Manager for Oracle’s x86 servers, focusing on Oracle’s operating systems and software. He previously spent more than a decade as a developer and architect of system management software. Josh has worked on system management for many of Oracle's hardware products ranging from the earliest blade systems to the latest Oracle x86 servers.

News, Perspektiven und jede Menge Gesprächsstoff - Der Oracle Partner Day 2012

- by A&C Redaktion

Was für ein Tag! Unter dem Motto „Maximize your Potential“ kamen über 470 Teilnehmerinnen und Teilnehmer beim Oracle Partner Day 2012 zusammen. Hier drehte sich alles um unsere Partner, die, wie Silvia Kaske, Senior Director Alliances & Channel Europe North, in ihrer Begrüßung betonte, „ein sehr wichtiger Baustein in der Wachstumsstrategie von Oracle“ sind. Wie einmalig diese Partnerschaft ist, betonte auch David Callaghan, Senior Vice President EMEA Alliances & Channel in seiner Keynote. Niemand sonst habe, so Callaghan, in ähnlichem Ausmaß wie Oracle, Hardware und Software tatsächlich integriert. So manche Anbieter würden zwar beides zusammenschnüren, aber bei weitem nicht so optimal abgestimmt und verflochten, wie beim „Red Stack“ von Oracle. Neben Keynotes von Jürgen Kunz, SVP Technology Northern Europe & Country Leader Germany, und Christian Werner, Senior Director Alliances & Channels Germany, zu Neuheiten und Entwicklungspotenzialen im Oracle Universum und den Präsentationen aus verschiedenen Spezialisierung-Fachgebieten, gab es sogar einen Blick in die Zukunft der IT: Der Informatiker Professor Hermann Maurer präsentierte nicht nur existierende und geplante Innovationen, etwa die berüchtigte Computerbrille, die bald das Smartphone abzulösen soll – eine ordentliche Portion Science-Fiction war auch dabei. Im Laufe des Tages nutzten diverse Partner die Möglichkeit, vor Ort den Test als OPN Implementation Specialist beim Testcenter Pearson Vue abzulegen. Viele Teilnehmer zeigten sich beeindruckt von den vielen guten Gesprächen untereinander und schöpften die Möglichkeit zum Networking und Erfahrungsaustausch voll aus. Bei einem so dichten Programm ist es natürlich schwierig, wirklich alles mitzunehmen. Daher haben wir die Präsentationen, die auf dem Oracle Partner Day gehalten wurden, hier in der Agenda noch einmal für Sie zusammengestellt. Spannend wurde es bei der Oracle Partner Award Ceremony: Zum zweiten Mal wurden dort deutsche Partner ausgezeichnet, die sich mit besonderem Engagement und Erfolg spezialisiert haben.

News, Perspektiven und jede Menge Gesprächsstoff - Der Oracle Partner Day 2012

- by A&C Redaktion

Was für ein Tag! Unter dem Motto „Maximize your Potential“ kamen über 470 Teilnehmerinnen und Teilnehmer beim Oracle Partner Day 2012 zusammen. Hier drehte sich alles um unsere Partner, die, wie Silvia Kaske, Senior Director Alliances & Channel Europe North, in ihrer Begrüßung betonte, „ein sehr wichtiger Baustein in der Wachstumsstrategie von Oracle“ sind. Wie einmalig diese Partnerschaft ist, betonte auch David Callaghan, Senior Vice President EMEA Alliances & Channel in seiner Keynote. Niemand sonst habe, so Callaghan, in ähnlichem Ausmaß wie Oracle, Hardware und Software tatsächlich integriert. So manche Anbieter würden zwar beides zusammenschnüren, aber bei weitem nicht so optimal abgestimmt und verflochten, wie beim „Red Stack“ von Oracle. Neben Keynotes von Jürgen Kunz, SVP Technology Northern Europe & Country Leader Germany, und Christian Werner, Senior Director Alliances & Channels Germany, zu Neuheiten und Entwicklungspotenzialen im Oracle Universum und den Präsentationen aus verschiedenen Spezialisierung-Fachgebieten, gab es sogar einen Blick in die Zukunft der IT: Der Informatiker Professor Hermann Maurer präsentierte nicht nur existierende und geplante Innovationen, etwa die berüchtigte Computerbrille, die bald das Smartphone abzulösen soll – eine ordentliche Portion Science-Fiction war auch dabei. Im Laufe des Tages nutzten diverse Partner die Möglichkeit, vor Ort den Test als OPN Implementation Specialist beim Testcenter Pearson Vue abzulegen. Viele Teilnehmer zeigten sich beeindruckt von den vielen guten Gesprächen untereinander und schöpften die Möglichkeit zum Networking und Erfahrungsaustausch voll aus. Bei einem so dichten Programm ist es natürlich schwierig, wirklich alles mitzunehmen. Daher haben wir die Präsentationen, die auf dem Oracle Partner Day gehalten wurden, hier in der Agenda noch einmal für Sie zusammengestellt. Spannend wurde es bei der Oracle Partner Award Ceremony: Zum zweiten Mal wurden dort deutsche Partner ausgezeichnet, die sich mit besonderem Engagement und Erfolg spezialisiert haben.

Customer Support Spotlight: Clemson University

- by cwarticki

I've begun a Customer Support Spotlight series that highlights our wonderful customers and Oracle loyalists. A week ago I visited Clemson University. As I travel to visit and educate our customers, I provide many useful tips/tricks and support best practices (as found on my blog and twitter). Most of all, I always discover an Oracle gem who deserves recognition for their hard work and advocacy. Meet George Manley. George is a Storage Engineer who has worked in Clemson's Data Center all through college, partially in the Hardware Architecture group and partially in the Storage group. George and the rest of the Storage Team work with most all of the storage technologies that they have here at Clemson. This includes a wide array of different vendors' disk arrays, with the most of them being Oracle/Sun 2540's. He also works with SAM/QFS, ACSLS, and our SL8500 Tape Libraries (all three Oracle/Sun products). (pictured L to R, Matt Schoger (Oracle), Mark Flores (Oracle) and George Manley) George was kind enough to take us for a data center tour. It was amazing. I rarely get to see the inside of data centers, and this one was massive. Clemson Computing and Information Technology’s physical resources include the main data center located in the Information Technology Center at the Innovation Campus and Technology Park. The core of Clemson’s computing infrastructure, the data center has 21,000 sq ft of raised floor and is powered by a 14MW substation. The ITC power capacity is 4.5MW. The data center is the home of both enterprise and HPC systems, and is staffed by CCIT staff on a 24 hour basis from a state of the art network operations center within the ITC. A smaller business continuance data center is located on the main campus. The data center serves a wide variety of purposes including HPC (supercomputing) resources which are shared with other Universities throughout the state, the state's medicaid processing system, and nearly all other needs for Clemson University. Yes, that's no typo (14,256 cores and 37TB of memory!!! Thanks for the tour George and thank you very much for your time. The tour was fantastic. I enjoyed getting to know your team and I look forward to many successes from Clemson using Oracle products. -Chris WartickiGlobal Customer Management

Ubuntu turns off instead of suspend / sleeping

- by Marcos

I'm using Ubuntu 11.10 on my notebook as the main OS. How ever, I've been facing a serious problem: Every time I try to suspend it, or it just stays idle for a while, the computer shuts down, instead of suspending. It actually seems to be suspended, but when I press the button the awake it, it turns on, the open works are all lost. How can i fix this? P.s: On windows 7 the suspend / sleep resumes just fine.

Fun with Sun Ray, 3D, Oracle VM x86 and SRIOV

- by wim.coekaerts

One of the things I like about my job is that I get to play around with stuff and make use of the technologies we work on in my teams. Sort of my own little playground. It allows me to study the products in great detail and put them to use in ways that individual product teams don't always intend them to be used for :) but that makes it fun. I have a lot of this set up at home because... work is sort of hobby and I just like to tinker with it. Anyway, a few weeks ago I was looking at my sun ray rig at home and how well 3D works. Google Earth and some basic opengl tests like glxspheres combined with virtualgl. It resulted in some very cool demos recorded with my little camera (sorry for the crappy quality of the video :-) : OVDC (soft client) on my mac Sun Ray 2FS Never mind the hickups during zoom, that's because I was using the scrollwheel on my mouse and I can't scroll uninterrupted :) Anyway, this is quite cool ! The setup for this was the following : Sun Ray on LAN, Sun Ray Server 5 latest installed on OL5.5 inside a VM running on Oracle VM 2.2 (hardware virt, with a virtual network (vif)) and the virtualgl rendering happened on another box (wopr5) that runs linux on a little atom D520 with an ION2 gpu. So network goes from Sun Ray to Sun Ray Server to wopr5 and back. Given that this is full screen 3D it puts a good amount of load on the network and it's pretty cool that SRS was just a VM :) So, separately, I had written a little blog entry about using sriov and oracle vm a while back. link to sriov blog entry Last night when I came home I wanted to do some more playing around with SRIOV and live migrate. To do this, I wanted to set up a VM with 2 network interfaces, one virtual network (vif) and then one that's one of the SRIOV virtual functions from my network card. Inside the guest they show as eth0 and eth1, and then bond them using a standard linux bonding device (bond0 here) with active active links. The goal here is that on live migrate, we would detach the VF (eth1 in guest in this case), the bond would then just hum along on eth0 (vif) we can live migrate the VM and then on the other server after the migrate completes we re-attach a VF to the VM there and eth1 pops up again and the bond uses both eth0/eth1 to do its work. So, to set this up, I figured, why not use my sun ray server VM because the 3D work generates a nice network load and is very latency/timing sensitive. In the end, I ran glxspheres on my sunray server (vm) displaying on my sun ray 2 fs and while that was running, I did my live migrate test of this vm (unplug pci VF, migrate, reconnect vf) and guess what, it just kept running :) veryyyyyy cool. now, it was supposed to, but it's always nice to see it actually work, for real. Here's a diagram of it. No gimics - just real technology at work ! enjoy :)

GlassFish Clustering with DCOM on Windows

- by ByronNevins

DCOM - Distributed COM, a Microsoft protocol for communicating with Windows machines. Why use DCOM? In GlassFish 3.1 SSH is used as the standard way to run commands on remote nodes for clustering. It is very difficult for users to get SSH configured properly on Windows. SSH does not come with Windows so we have to depend on third party tools. And then the user is forced to install and configure these tools -- which can be tricky. DCOM is available on all supported platforms. It is built-in to Windows. The idea is to use DCOM to communicate with remote Windows nodes. This has the huge advantage that the user has to do minimal, if any, configuration on the Windows nodes. Implementation HighlightsTwo open Source Libraries have been added to GlassFish: Jcifs – a SAMBA implementation in Java J-interop – A Java implementation for making DCOM calls to remote Windows computers. Note that any supported platform can use DCOM to work with Windows nodes -- not just Windows.E.g. you can have a Linux DAS work with Windows remote instances.All existing SSH commands now have a corresponding DCOM command – except for setup-ssh which isn’t needed for DCOM. validate-dcom is an all new command. New DCOM Commands create-node-dcom delete-node-dcom install-node-dcom list-nodes-dcom ping-node-dcom uninstall-node-dcom update-node-dcom validate-dcom setup-local-dcom (This is only available via Update Center for GlassFish 3.1.2) These commands are in-place in the trunk (4.0). And in the branch (3.1.2) Windows Configuration Challenges There are an infinite number of possible configurations of Windows if you look at it as a combination of main release, service-pack, special drivers, software, configuration etc. Later versions of Windows err on the side of tightening security be default. This means that the Windows host may need to have configuration changes made.These configuration changes mostly need to be made by the user. setup-local-dcom will assist you in making required changes to the Windows Registry. See the reference blogs for details. The validate-dcom Command validate-dcom is a crucial command. It should be run before any other commands. If it does not run successfully then there is no point in running other commands.The validate-dcom command must be used from a DAS machine to test a different Windows machine. If validate-dcom runs successfully you can be confident that all the DCOM commands will work. Conversely, the opposite is also true: If validate-dcom fails, then no DCOM commands will work. What validate-dcom does Verify that the remote host is not the local machine. Resolves the remote host name Checks that the remote DCOM port is being listened on (135, 139) Checks that the remote host’s File Sharing is enabled (port 445) It copies a file (a script) to the remote host to verify that SAMBA is working and authorization is correct It runs a script that it copied on-the-fly to the remote host. Tips and Tricks The bread and butter commands that use DCOM are existing commands like create-instance, start-instance etc. All of the commands that have dcom in their name are for dealing with the actual nodes. The way the software works is to call asadmin.bat on the remote machine and run a command. This means that you can track these commands easily on the remote machine with the usual tools. E.g. using AS_LOGFILE, looking at log files, etc. It’s easy to attach a debugger to the remote asadmin process, “just in time”, if necessary. How to debug the remote commands:Edit the asadmin.bat file that is in the glassfish/bin folder. Use glassfish/lib/nadmin.bat in GlassFish 4.0+Add these options to the java call:-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=1234 Now if you run, say start-instance on DAS, you can attach your debugger, at your leisure, to the remote machines port 1234. It will be running start-local-instance and patiently waiting for you to attach.
