  • Should Production Windows Web Servers (IIS & SQL) be in a domain?

    - by tlianza
    We have a few web servers and a few database servers. To date, they've been standalone machines that are not part of a domain. The web servers don't talk to each other, and the web servers talk to the database servers via SQL Auth. My concern with putting the machines in a domain together were added complexity - it's one more "thing" running, and doing "things" that could go wrong. risk - if a domain controller fails, am I now putting other machines at risk? However, in certain scenarios it does seem convenient for them to be on a domain, sharing credentials. For example, if I want to give the "services" control on one machine access to another machine (because Remote Desktop craps out) I need to go in and assign privileges on multiple machines - something that I believe Active Directory and Domain Accounts set to simplify. My question: I'm sure there are things I'm not considering here. Is there a best practice?

  • How to handle SalesForce WSDL files for sandbox and production sites in ASP.Net?

    - by Traveling Tech Guy
    I need to authenticate users and get info about them from an ASP.Net application. Since I have 2 sites (sandbox, production) and 2 org IDs - I needed to generate 2 SalesForce WSDL files. I diffed the 2 files (each about 600kb in size) and while they are 95% the same, there are enough differences strewn all over the place - enough for me to need to use them both. I added both as web references to my solution, and here's where my problem starts.Obviously, I cannot use both references in the same file, as they contain the same classes/functions. I had to write a quick-and-dirty solution over the weekend, so I just created 2 classes - each using a different web reference - but otherwise the exact functionality, and I use the appropriate one, based on the URL the user is coming from. This works well, but strikes me as a bad (read: quick-and-dirty) solution. My question: is there any way to do one or more of the following: change the web reference on the fly? use both web references in the same file, but put one in a different namespace? find a better solution to the whole situation? I nd up with a huge XmlSerializer.dll (3mb!) - probably due to using both huge WSDL files. Thanks for your time.

  • How to transform a production to LL(1) for a list separated by a semicolon?

    - by Subb
    Hi, I'm reading this introductory book on parsing (which is pretty good btw) and one of the exercice is to "build a parser for your favorite language." Since I don't want to die today, I thought I could do a parser for something relatively simple, ie a simplified CSS. Note: This book teach you how to right a LL(1) parser using the recursive-descent algorithm. So, as a sub-exercice, I am building the grammar from what I know of CSS. But I'm stuck on a production that I can't transform in LL(1) : //EBNF block = "{", declaration, {";", declaration}, [";"], "}" //BNF <block> =:: "{" <declaration> "}" <declaration> =:: <single-declaration> <opt-end> | <single-declaration> ";" <declaration> <opt-end> =:: "" | ";" This describe a CSS block. Valid block can have the form : { property : value } { property : value; } { property : value; property : value } { property : value; property : value; } ... The problem is with the optional ";" at the end, because it overlap with the starting character of {";", declaration}, so when my parser meet a semicolon in this context, it doesn't know what to do. The book talk about this problem, but in its example, the semicolon is obligatory, so the rule can be modified like this : block = "{", declaration, ";", {declaration, ";"}, "}" So, Is it possible to achieve what I'm trying to do using a LL(1) parser?

  • getting CS1502 compiler error on dev environment but not production.

    - by nw
    When I try to run my ASP.NET app from my development environment I get the following error message: Compiler Error Message: CS1502: The best overloaded method match for 'mmars.Printing.printFunctions.SetPrintSummaryProperties(mmars.contextInfo, ref mmars.Printing.printObjSummary)' has some invalid arguments. When I publish and run on our production server I don't get this error. It seems to compile fine when I build from the build menu (in fact if I change the second argument of the bolded function call below, i get a compiler error in visual studio), but now i've suddenly started getting this error message at runtime. So another question I have in addition to getting rid of the error is why is the .NET development server even trying to do JIT compilation on my project if it is already compiled into a DLL? Printing.printObjSummary myPrintObj = new Printing.printObjSummary(); Printing.printFunctions.SetPrintSummaryProperties(ci, ref myPrintObj); printObjects.Add(myPrintObj); This seems to have just suddenly appeared from nowhere today and it's extremely frustrating. Also, though there are no warnings at compile-time, when I get redirected to the page with that first compilation error there are many warnings like the following: Warning: CS0436: The type 'mmars.MMARSSummaryDataItem' in 'c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\root\3dad423c\40569048\App_Code.b0rgpkzr.4.cs' conflicts with the imported type 'mmars.MMARSSummaryDataItem' in 'c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\root\3dad423c\40569048\assembly\dl3\7179c19a\345f948c_ece7ca01\mmars.DLL'.

Is the webserver complaining about name conflicts in the source file and dll resulting from the source file?

  • Restoring dev db from production: Running a set of SQL scripts based on a list stored in a table?

    - by mattley
    I need to restore a backup from a production database and then automatically reapply SQL scripts (e.g. ALTER TABLE, INSERT, etc) to bring that db schema back to what was under development. There will be lots of scripts, from a handful of different developers. They won't all be in the same directory. My current plan is to list the scripts with the full filesystem path in table in a psuedo-system database. Then create a stored procedure in this database which will first run RESTORE DATABASE and then run a cursor over the list of scripts, creating a command string for SQLCMD for each script, and then executing that SQLCMD string for each script using xp_cmdshell. The sequence of cursor-sqlstring-xp_cmdshell-sqlcmd feels clumsy to me. Also, it requires turning on xp_cmdshell. I can't be the only one who has done something like this. Is there a cleaner way to run a set of scripts that are scattered around the filesystem on the server? Especially, a way that doesn't require xp_cmdshell?

  • How to deploy to multiple redundant production servers with "cap deploy"?

    - by Chad Johnson
    Capistrano is working great to deploy to a single server. However, I have multiple production API servers for my web application. When I deploy, my code needs to get deployed to every API server at once. Specifying each server manually is NOT the solution I am looking for (e.g. I don't want to do "cap api1 deploy; cap api2 deploy"). Is there a way, using Capistrano, to deploy to all servers at once, with just a simple "cap deploy"? I'm wondering what changes I would need to make to a typical deploy.rb file, whether I'd need to create a separate file for each server, and whether and how the Capfile would need to be changed. Also, I need to be able to specify a different deploy_to path for each server. And ideally, I wouldn't have to repeat things in different config files for different servers (eg. wouldn't have to specify :repository, :application, etc. multiple times). I have spent hours searching Google on this and looking through tutorials, but I have found nothing helpful. Here is a snippet from my current deploy.rb file: set :application, "testapplication" set :repository, "ssh://domain.com//srv/hg/#{application}" set :scm, :mercurial set :deploy_to, "/srv/www/#{application}" role :web, "domain.com" role :app, "domain.com" role :db, "domain.com", :primary => true, :norelease => true Should I just use the multistage extension and do this? task :deploy_everything do system "cap api1 deploy" system "cap api2 deploy" system "cap api2 deploy" end That could work, but I feel like this isn't what this extension is meant for...

  • Git development?production workflow – how to set up repo?

    - by Blixt
    I'm working on a relatively small, but fast-changing project (a web application) with a few other developers. We're using Git for source control. We started out creating a stable branch which is what is deployed to the live production web server. The master branch is what is deployed to a secondary "unstable" server for testing purposes. Whenever we felt that the master branch was ready to go live, we merged it into stable. However, we came to a point where we wanted one of the later master commits, but not some of the commits before it, so we used cherry-pick to pull that change into stable. This creates a new commit with the same change as the one in master, and it feels as if we're losing the nice history that Git otherwise provides. Are there better ways of handling this type of unstable/stable deployment model? One solution I thought of was using feature branches, and only ever merging a feature branch into master once we want it to go live. Then we'll tag every deployment instead of having a stable branch.

  • ASP.Net MVC - What replaces events to support loose coupling?

    - by James
    What feature(s) of ASP.Net MVC can replace the way events can be used in Webforms to support loosely coupled components. For example, take a simple pager control: A page number is clicked Pager fires off a "PageChange" event with the new page number This subscribing page/control received the event and handles initiating a call to fetch and bind new data. What tools are available in ASP.Net MVC to support Loose coupling Component re-usability Separation of logic for a single page/view (such a very complex "portal" type page).

  • What products support 3-digit region subtags, e.g., es-419 for Latin-American Spanish?

    - by Ektron Doug D
    What products support 3-digit region subtags, e.g., es-419 for Latin-American Spanish? Are web browsers, translation tools and translators familiar with these numeric codes in addition to the more common "es" or "es-ES"? I've already visited the following pages: W3C Choosing a Language Tag W3C Language tags in HTML and XML RFC 5646 Tags for Identifying Languages Microsoft National Language Support (NLS) API Reference

  • What is the state of C99 support in major compilers / toolchains?

    - by pkh
    A response to a comment I made here made me stop and think: "I don't really know what the state of C99 support is." Wikipedia gives details for a few compilers, but I'm not familiar enough with C99 to know all the bits and pieces of the standard, so I'm looking for a gestalt overview answer to the question: What is the state of C99 support in major compilers / toolchains?

  • Which browser versions do YouTube and Google Apps support?

    - by Alex
    Hi. We're building a site and wish to build for the same set of browsers Google Apps/Docs and YouTube support. Though not recommended, they seem to be detecting specific browsers/versions vs. features/functionality. What's the best way to support a minimum set of browsers while displaying a message to the users of older browsers to upgrade? What's the minimum set of browsers that the major sites are supporting? Thanks.

  • Does Doctrine 1.2 support importing indexes with Doctrine_Core::generateModelsFromDb function?

    - by Coagulant
    Does Doctrine 1.2 support importing indexes with Doctrine_Core::generateModelsFromDb() function? I need to make a migration between 2 database connections, one of them having unique index on 2 fields and one doesn't. And my migration is empty. It looks like Doctrine doesn't support indexes when importing from databae, other than those tied to relationship foreign keys. $changes = Doctrine_Core::generateMigrationsFromDiff($migrationsPath, array('doctrineOld'), array('doctrine'));

  • StarTeam trunk.

    - by Nix
    I have the unfortunate opportunity of source control via Borland's StarTeam. It unfortunately does very few things well, and one supreme weakness is its view management. I love SVN and come from an SVN mindset. Our issue is post production release we are spending countless hours merging changes into a "production support" environment. Please do not harass me this was not my doing, I inherited it and am trying to present a better way of managing the repository. It is not an option to switch to a different SCM tool. Current setup Product.1.0 (TRUNK, current production code, and at this level are pending bug fixes) Product.2.0(true trunk anything checked in gets tested, and then released next production cycle, a lot of changes occur in this view) My proposal is going to be to swap them, have all development be done on the trunk (Production), tag on releases, and as needed create child views to represent production support bug fixes. Production Production.2.0.SP.1 I can not find any documentation to support the above proposal so I am trying to get feedback on whether or not the change is a good idea and if there is anything you would recommend doing differently.
