  • Visual Studio Agents 2012 on Server 2003 SP2

    - by Corith Malin
    I'm attempting to build out our Lab Manager with TFS 2012. On a virtual machine running Server 2003 SP2 32bit, I'm attempting to install the Visual Studio Agents 2012 and am running into an error: Setup Failed! Install cannot continue because some required components failed. Microsoft .NET Framework 4.5 Asia Looking into it, the install log is erroring when it's attempting to install dotNetFx45_Full_x86_x64.exe component. Looking at that install log, it is failing with: The .NET Framework 4.5 is not supported on this operating system. So, I see according to the Agents 2012 MSDN documentation, that Server 2003 SP2 is supported by Agents 2012. But I also see that according to the .NET 4.5 MSDN documentation, Server 2003 isn't supported. So how do I install Agents 2012 on 2003 SP2 as the documentation implies I can?

  • One bigger Virtual Machine distributed across many OpenStack nodes [duplicate]

    - by flyer
    This question already has an answer here: Can a virtualized machine have the CPU and RAM resources of multiple underlying physical machines? 2 answers I just setup virtual machines on one hardware with Vagrant. I want to use a Puppet to configure them and next try to setup OpenStack. I am not sure If I am understanding how this should look at the end. Is it possible to have below architecture with OpenStack after all where I will run one Virtual Machine with Linux? ------------------------------- | VM with OS | ------------------------------- | NOVA | NOVA | NOVA | ------------------------------- | OpenStack | ------------------------------- | Node | Node | Node | ------------------------------- More details: In my environment Nodes are just virtual machines, but my question concerns separate Hardware nodes. If we imagine this Nodes(Novas) are placed on a separate machines (e.g. every has 4 cores) can I run one Virtual Machine across many OpenStack Nodes? Is it possible to aggregate the computation power of OpenStack in one virtual distributed operating system?

  • DoubleBuffering in Java

    - by DDP
    Hello there, I'm having some trouble implementing DoubleBuffer into my program. Before you faint from the wall of text, you should know that a lot of it is there just in case you need to know. The actual place where I think I'm having problems is in one method. I've recently looked up a tutorial on the gpwiki about double buffering, and decided to try and implement the code they had into the code I have that I'm trying to implement doublebuffer in. I get the following error: "java.lang.IllegalStateException: Component must have a valid peer". I don't know if it makes any difference if you know it or not, but the following is the code with the main method. This is just a Frame that displays the ChronosDisplay class inside it. I omitted irrelevant code with "..." public class CDM extends JFrame { public CDM(String str) { super("CD:M - "+str); try { ... ChronosDisplay theGame = new ChronosDisplay(str); ((Component)theGame).setFocusable(true); add(theGame); } catch(Exception e) { System.out.println("CDM ERROR: " +e); } } public static void main( String args[] ) { CDM run = new CDM("DP_Mini"); } } Here is the code where I think the problem resides (I think the problem is in the paint() method). This class is displayed in the CDM class public class ChronosDisplay extends Canvas implements Runnable { String mapName; public ChronosDisplay (String str) { mapName = str; new Thread(this).start(); setVisible(true); createBufferStrategy(2); } public void paint( Graphics window ) { BufferStrategy b = getBufferStrategy(); Graphics g = null; window.setColor(Color.white); try { g = b.getDrawGraphics(); paintMap(g); paintUnits(g); paintBullets(g); } finally { g.dispose(); } b.show(); Toolkit.getDefaultToolkit().sync(); } public void paintMap( Graphics window ) { TowerMap m = new TowerMap(); try { m = new TowerMap(mapName); for(int x=0; x<m.getRows()*50; x+=50) { for(int y = 0; y<m.getCols()*50; y+=50) { int tileType = m.getLocation(x/50,y/50); Image img; if(tileType == 0) { Tile0 t = new Tile0(x,y); t.draw(window); } ...// More similar if statements for other integers } catch(Exception e) ... } ...// Additional methods not shown here public void run() { try { while(true) { Thread.currentThread().sleep(20); repaint(); } } catch(Exception e) ... } } If you're curious (I doubt it matters), the draw() method in the Tile0 class is: public void draw( Graphics window ) { window.drawImage(img,getX(),getY(),50,50,null); } Any pointers, tips, or solutions are greatly appreciated. Thanks for your time! :D

  • How to determine why a burned DVD won't boot?

    - by cat pants
    So I have an interesting problem where a burned DVD of "debian-7.2.0-ia64-CD-1.iso" won't boot. The DVD is a DVD+RW. I have tried erasing, burning, and booting from "debian-live-7.0.0-i386-gnome-desktop+nonfree.iso" and that works fine, but I would rather install debian 7.2 with the x86-64 architecture. After burning "debian-7.2.0-ia64-CD-1.sio", I can mount the CD as well and it appears that all the files show up correctly. I was just wondering if there is any sort of boot sector I can try inspecting on the ISO to see if perhaps it is incorrect. Thanks!

  • Back up of Streaming server

    - by Maxwell
    I want to take a new streaming server for my website which generally holds videos and audio files. But how do we maintain backup of the streaming server if storage size is increasing day by day. Generally on Database servers, like Sql Server, backups can be easily taken and restored very easily as they do not occupy much space for medium range applications. On the other hand how can we take backup of streaming server? If the server fails, the there should be an alternative server / solution that should decrease downtime of the server. How is the back-end architecture of YouTube built to handle this?

  • How to set User Tile image Windows Server 2012?

    - by moontear
    I found this nice article of how to add a user tile image via code: http://joco.name/2010/12/06/i-discovered-the-new-windows-user-tile-api/ This is also explained in depth here: http://msitpros.com/?p=1036 I have problems with doing this in Windows Server 2012. Whenever I run the code: using System; using System.Runtime.InteropServices; namespace FejesJoco { class Program { [DllImport("shell32.dll", EntryPoint = "#262", CharSet = CharSet.Unicode, PreserveSig = false)] public static extern void SetUserTile(string username, int whatever, string picpath); [STAThread] static void Main(string[] args) { SetUserTile(args[0], 0, args[1]); } } } I get an exception: Error HRESULT E_FAIL has been returned from a call to a COM component. Can anyone get this to work and add a user tile image via code?

  • Mono-LibreOffice System.TypeLoadException

    - by Marco
    In the past I wrote a C# library to work with OpenOffice and this worked fine both in Windows than under Ubuntu with Mono. Part of this library is published here as accepted answer. In these days I discovered that Ubuntu decided to move to LibreOffice, so I tried my library with LibreOffice latest stable release. While under Windows it's working perfectly, under Linux I receive this error: Unhandled Exception: System.TypeLoadException: A type load exception has occurred. [ERROR] FATAL UNHANDLED EXCEPTION: System.TypeLoadException: A type load exception has occurred. Usually Mono tells us which library can't load, so I can install correct package and everything is OK, but in this case I really don't know what's going bad. I'm using Ubuntu oneiric and my library is compiled with Framework 4.0. Under Windows I had to write this into app.config: <?xml version="1.0"?> <configuration> <startup useLegacyV2RuntimeActivationPolicy="true"> <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0,Profile=Client"/> </startup> </configuration> because LibreOffice assemblies uses Framework 2.0 (I think). How can I find the reason of this error to solve it? Thanks UPDATE: Even compiling with Framework 2.0 problem (as expected) is the same. Problem (I think) is that Mono is not finding cli-uno-bridge package (installable on previous Ubuntu releases and now marked as superseded), but I cannot be sure. UPDATE 2: I created a test console application referencing cli-uno dlls on Windows (they are registered in GAC_32 and GAC_MSIL). CONSOLE app static void Main(string[] args) { Console.WriteLine("Starting"); string dir = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location); string doc = Path.Combine(dir, "Liberatoria siti web.docx"); using (QOpenOffice.OpenOffice oo = new QOpenOffice.OpenOffice()) { if (!oo.Init()) return; oo.Load(doc, true); oo.ExportToPdf(Path.ChangeExtension(doc, ".pdf")); } } LIBRARY: using unoidl.com.sun.star.lang; using unoidl.com.sun.star.uno; using unoidl.com.sun.star.container; using unoidl.com.sun.star.frame; using unoidl.com.sun.star.beans; using unoidl.com.sun.star.view; using unoidl.com.sun.star.document; using System.Collections.Generic; using System.IO; using System; namespace QOpenOffice { class OpenOffice : IDisposable { private XComponentContext context; private XMultiServiceFactory service; private XComponentLoader component; private XComponent doc; public bool Init() { Console.WriteLine("Entering Init()"); try { context = uno.util.Bootstrap.bootstrap(); service = (XMultiServiceFactory)context.getServiceManager(); component = (XComponentLoader)service.createInstance("com.sun.star.frame.Desktop"); XNameContainer filters = (XNameContainer)service.createInstance("com.sun.star.document.FilterFactory"); return true; } catch (System.Exception ex) { Console.WriteLine(ex.Message); if (ex.InnerException != null) Console.WriteLine(ex.InnerException.Message); return false; } } } } but I'm not able to see "Starting" !!! If I comment using(...) on application, I see line on console... so I think it's something wrong in DLL. There I'm not able to see "Entering Init()" message on Init(). Behaviour is the same when LibreOffice is not installed and when it is !!! try..catch block is not executed...

  • Cables for building a computer

    - by Faken
    I'm looking at building a computer and I have already done a whole bunch of research the topic and I think I know what I'm doing. My question is where do all the cables required for connecting everything come from? I'm pretty sure that the cables required come from their respective components (power connectors from the power supply, assorted cables from the motherboard, ect). However nowhere have I seen it explicitly stated that the cables come with the component I am buying. Just to confirm, if I buy all the components needed for a basic computer (CPU, motherboard, power supply, case, ram, video card, hard drive) from a website, say newegg, will I have all the screws, cables,connectors, and components to put together a working computer or will I need to buy some cables somewhere?

  • Forcing a transaction to rollback on validation errors in Seam

    - by Chris Williams
    Quick version: We're looking for a way to force a transaction to rollback when specific situations occur during the execution of a method on a backing bean but we'd like the rollback to happen without having to show the user a generic 500 error page. Instead, we'd like the user to see the form she just submitted and a FacesMessage that indicates what the problem was. Long version: We've got a few backing beans that use components to perform a few related operations in the database (using JPA/Hibernate). During the process, an error can occur after some of the database operations have happened. This could be for a few different reasons but for this question, let's assume there's been a validation error that is detected after some DB writes have happened that weren't detectible before the writes occurred. When this happens, we'd like to make sure all of the db changes up to this point will be rolled back. Seam can deal with this because if you throw a RuntimeException out of the current FacesRequest, Seam will rollback the current transaction. The problem with this is that the user is shown a generic error page. In our case, we'd actually like the user to be shown the page she was on with a descriptive message about what went wrong, and have the opportunity to correct the bad input that caused the problem. The solution we've come up with is to throw an Exception from the component that discovers the validation problem with the annotation: @ApplicationException( rollback = true ) Then our backing bean can catch this exception, assume the component that threw it has published the appropriate FacesMessage, and simply return null to take the user back to the input page with the error displayed. The ApplicationException annotation tells Seam to rollback the transaction and we're not showing the user a generic error page. This worked well for the first place we used it that happened to only be doing inserts. The second place we tried to use it, we have to delete something during the process. In this second case, everything works if there's no validation error. If a validation error does happen, the rollback Exception is thrown and the transaction is marked for rollback. Even if no database modifications have happened to be rolled back, when the user fixes the bad data and re-submits the page, we're getting: java.lang.IllegalArgumentException: Removing a detached instance The detached instance is lazily loaded from another object (there's a many to one relationship). That parent object is loaded when the backing bean is instantiated. Because the transaction was rolled back after the validation error, the object is now detached. Our next step was to change this page from conversation scope to page scope. When we did this, Seam can't even render the page after the validation error because our page has to hit the DB to render and the transaction has been marked for rollback. So my question is: how are other people dealing with handling errors cleanly and properly managing transactions at the same time? Better yet, I'd love to be able to use everything we have now if someone can spot something I'm doing wrong that would be relatively easy to fix. I've read the Seam Framework article on Unified error page and exception handling but this is geared more towards more generic errors your application might encounter.

  • monitoring TCP/IP performance on Solaris

    - by Andy Faibishenko
    I am trying to tune a high message traffic system running on Solaris. The architecture is a large number (600) of clients which connect via TCP to a big Solaris server and then send/receive relatively small messages (.5 to 1K payload) at high rates. The goal is to minimize the latency of each message processed. I suspect that the TCP stack of the server is getting overwhelmed by all the traffic. What are some commands/metrics that I can use to confirm this, and in case this is true, what is the best way to alleviate this bottleneck?

  • What is "2LUN" mode in connection with RAID?

    - by naxa
    I've came across RAID products that also list JBOD (just a bunch of disks) mode and 2LUN mode. What the heck is 2LUN mode? I could not find a description; the closest thing seems to be LUN 'logical unit number' but I don't get the 2LUN thing. UPDATE 1 This is what Wikipedia has to say about JBOD: JBOD (derived from "just a bunch of disks"): an architecture involving multiple hard drives, while making them accessible either as independent hard drives, or as a combined (spanned) single logical volume with no actual RAID functionality. So JBOD can actually mean two different (albeit related) things. Answer of Guest says 2LUN means no spanning. Does this suggest that 2LUN would simply mean the JBOD-variant with no span?

  • Disk / system configuration for log collection / syslog server

    - by Konrads
    I am looking into building a syslog / logging infrastructure and am pondering about some architecture best practices. Essentially, I see that a syslog system needs to support two conflicting workloads: log collection. Potentially massive streams of data need to be written quickly to disks and indexed. log querying. logs will be queried by both fixed fields such as date and source as well as text search. What is the best disk/system setup assuming I'd like to keep it to a single server for now? Should I use SSDs or ramdisk to off-load some processing? some disks in stripe and some in raid5? I am particularly eyeing Graylog2 with ElasticSearch/MongoDB

  • RHEL Cluster FAIL after changing time on system

  • distributed, fault-tolerant network block device

    - by gucki
    I'm looking for a distributed, fault-tolerant network storage system which exposes block devices (not filesystems) on the clients. A client's block device should write simultaneously to several storage nodes A client's block device should not fail as long as not all storage nodes backing it went down The master should automatically redistribute storages' data when a storage node fails or gets added/ removed A single master (which is for metadata only) is fine So ideally the architecture would be very similar to moosefs (http://www.moosefs.org/) but instead of exposing a real filesystem mounted using a fuse client it'd expose block devices on the clients. I know of iscsi and drbd but both don't seem to offer what I'm looking for. Or am I missing something?

  • When using TCP load balancing with HAProxy, does all outbound traffic flow through the LB?

    - by user122875
    I am setting up an app to be hosted using VMs(probably amazon, but that is not set in stone) which will require both HTTP load balancing and load balancing a large number(50k or so if possible) of persistant TCP connections. The amount of data is not all that high, but updates are frequent. Right now I am evaluating load balancers and am a bit confused about the architecture of HAProxy. If I use HAProxy to balance the TCP connections, will all the resulting traffic have to flow through the load balancer? If so, would another solution(such as LVS or even nginx_tcp_proxy_module) be a better fit?

  • catch-22 with apt-get

    - by Mark J Seger
    I'd recently installed a package and discovered my scp stopped working. After removing and installing some things I got it fixed but then I stated getting errors in apt-get about dpkg: error: configuration error: /etc/dpkg/dpkg.cfg.d/multiarch:1: unknown option 'foreign-architecture' so I commented it out and thought that fixed the problem until I discovered the chrome icon in my launcher turned into a ? and chrome no longer worked. I tried to reinstall it and got the apt-get error: "ambiguous package name 'libglib2.0-0' with more than one installed instance" if I try to remove libglib2 I get the error The following packages have unmet dependencies: iceape-browser : Depends: iceape but it is not going to be installed iceape-chatzilla : Depends: iceape (>= 2.7.11) but it is not going to be installed Depends: iceape (<= 2.7.11-1.1~) but it is not going to be installed E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages. so then I tried to remove icape-browser and it complained about the 2 instances of libglinb2. in fact virtually any command I issue does the same thing so I don't know what I can do to untangle things.

  • Media Sharing on Windows Server 2008 R2

    - by HCL
    I want a Server 2008R2 (x64) to act as DNLA-Server. I remember I tried this with a Server 2008 about two years ago and this was only possible with some ugly hacks. Is it on Server 2008R2 now possible to enable Windows MediaPlayer Media-Sharing by installing the desktop experience packet? Has someone already experience on this. Or is there another possibility to allow media sharing on a Server 2008R2 "the designated way"? I remember that on Server 2008 the way was to install the old MediaConnect-Pacakge. But I hesitate to install such a component on a server. Anciently I installed VirtualServer with Vista and enabled the media server there in, but this seems to me somewhat overkill for such a simple task.

  • Working WCF WebServices with NLB server

    - by gguth
    Im starting the architecture of a new project using WCF, but im not the right person to make some network considerations, so im doing some research but cannot find the answers to these questions: We´ll host the WCF service in a common Windows Service app in 2 servers and we´ll have another server to make the Load-Balancing job using the WNLB. The fact that we are hosting the WCF in a Windows Service app can disturb the NLB job? Before my research i thought the load balancing was tought to configure, but with NLB it seems to be very simple, its really that simple? Note: The binding will be basicHttpBinding

  • Suscribers locking during snapshot replication

    - by remi_bourgarel
    Hi all :) Here is my architecture : I have a main server and 4 replica (the servers are synchronized with snapshot replication). The replication is working fine, except for one thing : during the replication a lot of SELECT request on one of the replica fail with a time-out. Here are my questions : Can I avoid these time-out ? If I can't : how can I detect the start and the end of the replication to redirect all the request on one of the replica to the main ? Thanks Sorry if you already answered to that kind of question but I couldn't find anything.

  • MouseMotionListener inside JTable

    - by Harish
    I am trying to add MouseMotion event to the label and move it based on the dragging of the mouse and make it move along with my mouse.However the mousemotion is very difficult to control making this action not usable. Here is the code import java.awt.Color; import java.awt.Component; import java.awt.event.MouseEvent; import java.awt.event.MouseMotionListener; import javax.swing.BorderFactory; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JScrollPane; import javax.swing.JTable; import javax.swing.SwingConstants; import javax.swing.SwingUtilities; import javax.swing.table.DefaultTableCellRenderer; import javax.swing.table.DefaultTableModel; public class TableTest { public TableTest() { String[] columnNames = { "FileName", "Integer" }; Object[][] data = { { new FileName("AAA.jpg", Color.YELLOW), new Integer(2) }, { new FileName("BBB.png", Color.GREEN), new FileName("BBB.png", Color.GREEN) }, { new FileName("CCC.jpg", Color.RED), new Integer(-1) }, }; DefaultTableModel model = new DefaultTableModel(data, columnNames) { public Class getColumnClass(int column) { System.out.println("column is" + column); return getValueAt(0, column).getClass(); } }; JTable table = new JTable(model); //JTable table = new JTable(data, columnNames); table.setDefaultRenderer(FileName.class, new FileNameCellRenderer()); final JLabel label = new JLabel("TESTING", SwingConstants.CENTER); label.setBackground(java.awt.Color.RED); label.setBounds(450, 100, 90, 20); label.setOpaque(true); label.setVisible(true); label.addMouseMotionListener(new MouseMotionListener() { public void mouseDragged(MouseEvent arg0) { label.setBounds(arg0.getX(), arg0.getY(), 90, 20); } public void mouseMoved(MouseEvent arg0) { // TODO Auto-generated method stub } }); table.add(label); JFrame frame = new JFrame(); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.getContentPane().add(table); frame.setSize(800, 600); frame.setLocationRelativeTo(null); frame.setVisible(true); } static class FileNameCellRenderer extends DefaultTableCellRenderer { public Component getTableCellRendererComponent(JTable table, Object v, boolean isSelected, boolean hasFocus, int row, int column) { super.getTableCellRendererComponent(table, v, isSelected, hasFocus, row, column); FileName fn = (FileName) v; setBorder(BorderFactory.createMatteBorder(0, 60, 0, 0, new java.awt.Color(143, 188, 143))); return this; } } static class FileName { public final Color color; public final String label; FileName(String l, Color c) { this.label = l; this.color = c; } public String toString() { return label; } } public static void main(String[] args) { SwingUtilities.invokeLater(new Runnable() { public void run() { new TableTest(); } }); } } I just want to make the label follow the label follow my mouse and the label should be attached to the table.Is there an easy way than this.

  • Java Framework Choice Question.

    - by Sarang
    We do have many frameworks available in Java. Struts, Swing, JSF 2.0, Spring etc are used as per their priority. Actually, I don't know how many they are as well! But, as I am fresher to Java, even learning after their architecture, I cannot decide which framework can be used with what type of Projects ! Also, I am confused with mixed use of framework like Spring + JSF. What is the benefit to it ? Another thing making me confusing is about the UI components available in market. Like, we do have Primefaces, Ice-faces, MyFaces, Rich-faces. They may or may not have been supporting AJAX in-built. They may contains some bugs as well. What is best choice for Framework + UI component that can directly provide a best feet solution for any project ?
