  • ZooKeeper and RabbitMQ/Qpid together - overkill or a good combination?

    - by Chris Sears
    Greetings, I'm evaluating some components for a multi-data center distributed system. We're going to be using message queues (via either RabbitMQ or Qpid) so agents can make asynchronous requests to other agents without worrying about addressing, routing, load balancing or retransmission. In many cases, the agents will be interacting with components that were not designed for highly concurrent access, so locking and cross-agent coordination will be needed to avoid race conditions. Also, we'd like the system to automatically respond to agent or data center failures. With the above use cases in mind, ZooKeeper seemed like it might be a good fit. But I'm wondering if trying to use both ZK and message queuing is overkill. It seems like what Zookeeper does could be accomplished by my own cluster manager using AMQP messaging, but that would be hard to get really right. On the other hand, I've seen some examples where ZooKeeper was used to implement message queuing, but I think RabbitMQ/Qpid are a more natural fit for that. Has anyone out there used a combination like this? Thanks in advance, -Chris

  • Grails - attempting to include HTPPBuilder - Linkage error

    - by Stefan Kendall
    When I run grails install-dependency, I get this. java.lang.LinkageError: loader constraint violation: loader (instance of <bootloader>) previously initiated loading for a different type with name "org/xml/sax/SAXParseException" What's wrong? I've not used grails dependency management before, and this is rather cryptic. repositories { grailsPlugins() grailsHome() mavenLocal() mavenCentral() } dependencies { runtime 'org.codehaus.groovy.modules.http-builder:http-builder:0.5.0' }

  • Ubiquitous way to get the file system root of a .NET WEB application

    - by Eddie
    Similar to Ubiquitous way to get the root directory an application is running in via C#, but that question seems to be related to Win Forms. How would the same be done for Web Forms? I was using... HttpContext.Current.Server.MapPath("~") This works great for handling HTTP requests but seems not to work if a scheduler like Quartz.NET invokes a job (the problem I am having). The HttpContext.Current is null in that scenario since an actual HTTP request is not made.

  • Creating a System.Web.UI.Page programatically in IHTTPHandler

    - by ObiWanKenobi
    I am trying to use the ASP.NET (3.5) "Routing Module" functionality to create custom pages based on the contents of the URL. Various articles, such as this one: http://blogs.msdn.com/mikeormond/archive/2008/05/14/using-asp-net-routing-independent-of-mvc.aspx explain how to use ASP.NET Routing to branch to existing pages on the web server. What I would like to do is create the page on-the-fly using code. My first attempt looks like this: public class SimpleRouteHandler : IRouteHandler { public IHttpHandler GetHttpHandler(RequestContext requestContext) { string pageName = requestContext.RouteData.GetRequiredString("PageName"); Page myPage = new Page(); myPage.Response.Write("hello " + pageName); return myPage; } } But this throws an HTTPException saying "Response is not available in this context." at the Response.Write statement. Any ideas on how to proceed? UPDATE: In the end, I went with an approach based on IHttpModule, which turned out to be rather easy.

  • Is there a free web file manager like Plesk or cPanel in ASP.Net

    - by Ron Klein
    I'm looking for a free, open-sourced web application written in C#/VB.Net on top of ASP.Net, which functions like Plesk or cPanel when it comes to (remote) file management. Something that simulates a regular FTP client, but actually displays web pages over HTTP, with the following functions: Create Folder Rename File/Folder Delete File/Folder Change Timestamp ("Touch") Move Archive etc. I saw a few commercial tools, but nothing when it comes to OSS. Any ideas? links?

  • HTTP HEAD Request and System.Web.Mvc.FileResult

    - by mnero0429
    I'm using BITS to make requests to a ASP.NET MVC controller method named Source that returns a FileResult. I know the type FilePathResult uses HttpResponse.TransmitFile, but I don't know if HttpResponse.TransmitFile actually writes the file to the response stream regardless of the request type. My question is, does FileResult only include the header information on HEAD requests, or does it transmit the file regardless of the request type? Or, do I have to account for HEAD requests myself?

  • Database designing for a bug tracking system in SQL

    - by Yasser
    I am an ASP.NET developer and I really dont do such of database stuff. But for my open source project on Codeplex I am required to setup a database schema for the project. So reading from here and there I have managed to do the following. As being new to database schema designing, I wanted some one else who has a better idea on this topic to help me identify any issues with this design. Most of the relationships are self explanatory I think, but still I will jot each one down. The two keys between UserProfile and Issues are for relationships between UserId and IssueCreatedBy and IssueClosedBy Thanks

  • How to add system property equivalent to java -D in Ant

    - by Shervin
    Hi. I need to set java -Djava.library.path=/some/path and I want to do it when I am running my ant script, building my jar. I think I have to use <sysproperty key="java.library.path" value="/some/path"/> but it doesnt work. I cannot make the syntax work. The only thing I have Googled and found is sysproperty in conjunction with <java classname> but that doesnt make any sense to me. I am not sure if this is relevant, but I am using ant to create a ear and deploying this ear in JBoss.

  • ASP.NET application developed in 32 bit environment not working in 64 bit environment

    - by jgonchik
    We have developed an ASP.NET website on a Windows 7 - 32 bit platform using Visual Studio 2008. This website is being hosted at a hosting company where we share a server with hundreds of other ASP.NET websites. We are in the process of changing our hosting to a dedicated Windows 2008 - 64 bit server. We have installed Visual Studio on this new server in order to debug our application. If we try to start the application on this new server using Visual Studios 2008's own web server (not IIS 7) we get the error below. We have tried to compile the application in both 32 as well as 64 bit mode. We also tried to compile to "Any CPU". But nothing helps. We also tried running Visual Studio as an administrator but without success. We get the following error: Server Error in '/' Application. The specified module could not be found. (Exception from HRESULT: 0x8007007E) Description: An unhandled exception occurred during the execution of the current web request.

  • About fork system call and global variables

    - by lurks
    I have this program in C++ that forks two new processes: #include <pthread.h> #include <iostream> #include <unistd.h> #include <sys/types.h> #include <sys/wait.h> #include <cstdlib> using namespace std; int shared; void func(){ extern int shared; for (int i=0; i<10;i++) shared++; cout<<"Process "<<getpid()<<", shared " <<shared<<", &shared " <<&shared<<endl; } int main(){ extern int shared; pid_t p1,p2; int status; shared=0; if ((p1=fork())==0) {func();exit(0);}; if ((p2=fork())==0) {func();exit(0);}; for(int i=0;i<10;i++) shared++; waitpid(p1,&status,0); waitpid(p2,&status,0);; cout<<"shared variable is: "<<shared<<endl; cout<<"Process "<<getpid()<<", shared " <<shared<<", &shared " <<&shared<<endl; } The two forked processes make an increment on the shared variables and the parent process does the same. As the variable belongs to the data segment of each process, the final value is 10 because the increment is independent. However, the memory address of the shared variables is the same, you can try compiling and watching the output of the program. How can that be explained ? I cannot understand that, I thought I knew how the fork() works, but this seems very odd.. I need an explanation on why the address is the same, although they are separate variables.

  • Integrate with Hawk Monitoring System

    - by Joel Martinez
    Hello, I am looking to integrate an existing product with Hawk (http://www.hawkms.com/), which our application support team uses to keep an eye on operations. I've never used the product so I was wondering if anyone could point me to some resources about how to expose performance data so that it can be monitored with Hawk. Specifically, the technologies we're using is asp.net and wcf ... but resources on other technology stacks would still be useful if they are available. Thanks!

  • Good source for studying professional software development with Visual Studio 2010?

    - by Ben
    I spent a lot of time reading blogs and tutorials on the Net regarding how to do this and that with VS2010, but I thought it would be better to learn it in a more systematic way. Do you know of a good website/book that will teach me how to use Visual Studio 2010/2008 Team System + Microsoft Project to perform various tasks from Project Management to code development and testing in the way the software was designed for? Thank you.

  • Which operating systems book should I go for?

    - by pecker
    Hi, I'm in a confusion. For our course (1 year ago) I used Stallings. I read it. It was fine. But I don't own any operating system's book. I want to buy a book on operating systems. I'm confused!! which one to pick? Modern Operating Systems (3rd Edition) ~ Andrew S. Tanenbaum (Author) Operating System Concepts ~ Abraham Silberschatz , Peter B. Galvin, Greg Gagne Operating Systems: Internals and Design Principles (6th Edition) ~ William Stallings I've plans of getting into development of realworld operating systems : Linux, Unix & Windows Driver Development. I know that for each of these there are specific books available. But I feel one should have a basic book on the shelf. So, which one to go for?

  • version control on large files

    - by Dustin Getz
    We happily use SVN for SCM at work. Currently I've got our binary assets in the same SVN repository as our code. SVN supports very large files (it transmits them 'streamily' to keep memory usage sane), but it is SLOOWWWWW. What asset management software do you recommend, for about a GB (and growing) worth of assets? We would prefer branching and merging (different assets & config files go to different customers).

  • Embedding an existing exe file into another program

    - by Milad
    Is there a way to link an existing .exe file with other C++ source files during compilation? What I'm actually trying to do is to compress and decompress some files in my console program using LZMA(7zip) SDK but unfortunately it's very difficult to use for a newbie. There is a command line version of LZMA called 7za.exe and I am wondering if I can somehow embed it into my program and use it like a function. It can be easily used with system() function (which seems to be a very dangerous thing to use) but then if I send my program to someone who doesn't have 7za.exe in the right folder it won't work. I came across CreateProcess() function in windows.h header files but it seems to achieve what system() does in a more proper and advanced way. I don't know if it can actually link the exe file like an object file during compilation
