  • URL Redirect Configuration in Virtualhost for a Single Page Web Application

    - by fenderplayer
    I have a web application under development that I am running locally. The home page of the application is fetched with the following url: http://local.dev/myapp/index.shtml When the app runs, javascript on the webpage maintains the url and the app state internally. Some of the other urls read as: http://local.dev/myapp/results?param1=val1&param2=val2 http://local.dev/myapp/someResource Note that there are no pages named results.html or someResource.html on my web server. They are just made up URLs to simulate RESTfulness in the single page app. All the app code - javascript, css etc - is present in the index.shtml file So, essentially, the question is how can I redirect all requests to the first URL above? Here's how the vhost configuration looks like: <VirtualHost 0.0.0.0:80> ServerAdmin [email protected] DocumentRoot "/Users/Me/mySites" ServerName local.dev RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(myapp|myapp2)\/results\?.+$ $1/index.shtml [R=301,L] <Directory "/Users/Me/mySites/"> Options +Includes Indexes MultiViews FollowSymlinks AllowOverride All Order allow,deny Allow from all </Directory> ErrorLog "/private/var/log/apache2/error.log" CustomLog "/private/var/log/apache2/access.log" common </VirtualHost> But this doesn't seem to work. Requesting the other URLs directly results in 404 error.

  • IIS7 can't read web.config on shared Mac filesystem

    - by RobG
    I'm running a VirtualBox virtualized Windows 2008 Server on my Mac, just finished setting it up today. On it, I have SQL Server 2008, IIS and ColdFusion 9. I want to serve websites from my Mac filesystem (for development purposes). So I created a new website in IIS and pointed it at the appropriate path using a UNC path: \vboxsvr\rob\Sites\testsite, which contains the ColdFusion code and a web.config file. When I attempt to modify the file at all, or view the site in a web browser, I get an error: HTTP 500.19 - Internal Server Error The requested page cannot be accessed because the related configuration data for the page is invalid. I did some Googling, and found several similar problems, but nothing exactly like I have. The closest one seemed to indicate permissions. So I recreated the site and set it up to allow the Administrator (in Windows) to access the stuff. That didn't help. I can read/modify the files just fine from within Windows, but IIS itself can't seem to do it. What do I need to do to fix this? Thanks!

  • Windows/IIS Hosting :: How much is too much?

    - by bsisupport
    I have 4 Windows 2003 servers running IIS 6. These servers host a bunch of unique web sites (in that they are all different in build/architecture/etc). The code behind these sites range from straight HTML, classic ASP, and 1.1/2.0/3.x flavors of .NET. Some (most) of the sites use a SQL backend, which is hosted on one or two different servers – not the IIS servers themselves. No virtualization on these servers and no load balancing for these particular sites. The problem I’m running into is coming up with some baseline metrics to determine, or basically come up with a “baseline score” to know when a web server has reached its hosting limit. Today, some basic information about each server is used: how much bandwidth does the server pump out, hard drive space availability, and basic (very basic) RAM & CPU utilization (what it looks like at peak traffic times.) I would be grateful if those of you that are 1000x smarter than I am could indulge me with your methods of managing IIS environments. Whether performance monitoring specifics, “score” determination as I’m trying to determine, or the obvious combination of both. Thanks in advance.

  • Why does my SQL Server use AWE memory? and why is this not visible in RAMMap?

    - by Marnix Klooster
    We have a Windows Server 2008 R2 (64-bit) 8GB server where, according to Sysinternals RAMMap, 2GB of memory is allocated using AWE. As far as I understood, this means that these pages stay in physical memory and are never pushed out. This causes other apps to be pushed out of physical memory. In RAMMap, on the Physical Pages tab, the Process column is empty for all of the AWE pages. We run SQL Server on that box, but (through SQL Server Management Studio, under Server Properties - Memory, under Server memory options) it says is configured not to use AWE. However, when stopping SQL Server, the AWE pages are suddenly gone. So it really is the culprit. So I have three questions: Why does RAMMap not know/show that a SQL Server process is responsible for that AWE memory? Why does SQL Server Management Studio say that AWE memory is not used? How do we make configure SQL Server to really not use AWE memory?

  • How can I determine what is causing SQL Server 2008 Express to hang Windows 7?

    - by thelaughingdm
    I have SQL Server Express 2008 installed on a Windows 7 (32-bit) developer workstation. Whenever I run an application that accesses SQL Server the Windows 7 shell hangs when the application closes. Applications like Windows Explorer and Task Manager become completely unresponsive. The task bar will not allow any interaction. The only way to recover the system is to power cycle. Two of the applications in use when this happens are NUnit and SQL Server Management Studio. NUnit always runs the unit tests that interact with the database fine. SQL Server Management Studio will sometimes cause the problem while trying to explore the database. The Windows event log does not show any events that are obviously connected to the problem. I have reverted and reinstalled SQL Server Express 2008 several times. What can be done to identify what is causing SQL Server Express 2008 to hang the Windows 7 shell?

  • Can web apps allow fast data-typists to "type-ahead"?

    - by user61852
    In some data entry contexts, I've seen data typists, type really fast and know so well the app they use, and have a mechanic quality in their work so that they can "type ahead", ie continue typing and "tab-bing" and "enter-ing" faster than the display updates, so that in many occasions they are typing in the data for the next form before it draws itself. Then when this next entry form appears, their keystrokes fill the text boxes and they continue typing, selecting etc. In contexts like this, this speed is desirable, since this persons are really productive. I think this "type ahead of time" is only possible in desktop apps, but I may be wrong. My question is whether this way of handling the keyboard buffer (which in desktop apps require no extra programming) is achievable in web apps, or is this impossible because of the way web apps work, handle sessions, etc (network latency and the overhead of generating new web pages ) ? Edit: By "type ahead" I mean "keyboard type ahead" (typing faster than the next entry form can load), not suggets-as-you-type-like-google type ahead. Typeahead is a feature of computers and software (and some typewriters) that enables users to continue typing regardless of program or computer operation—the user may type in whatever speed he or she desires, and if the receiving software is busy at the time it will be called to handle this later. Often this means that keystrokes entered will not be displayed on the screen immediately. This programming technique for handling user what is known as a keyboard buffer.

  • Breadcrumbs in a modern web application, make sense? [on hold]

    - by Xtreme Biker
    I'm currently beginning with the development of a new web application. The whole web application is going to be bookmarkable and all the pages accesible via GET requests and url parameters. Having said that, let's suppose I've got three entities in my application, Customer, Team and City. Each Customer and Team belong to a city and I've got a city-detail page which displays the detail for a concrete city. So next navigation cases are possible: Customers - Customer detail (id=2) - City detail (id=3) Football teams - Team detail (id=5) - City detail (id=3) Cities - City detail (id=3) There are three possible ways of ending up in a city detail view. My question is, does it make sense to implement a breadcrumb to show such a history, having it available in the browser itself? Would it be more appropiate to show a breadcrumb with the last case, no matter where we're coming from (hierarchical breadcrumb)? That's what Jakob Nielsen points out here: Offering users a Hansel-and-Gretel-style history trail is basically useless, because it simply duplicates functionality offered by the Back button, which is the Web’s second-most-used feature. A history trail can also be confusing: users often wander in circles or go to the wrong site sections. Having each point in a confused progression at the top of the current page doesn’t offer much help. Finally, a history trail is useless for users who arrive directly at a page deep within the site. Also, even if the history trail seems the most natural way to implement it, it requires an extra effort to keep the whole track being HTTP a stateless mean.

  • SQL Server IO handling mechanism can be severely affected by high CPU usage

    - by sqlworkshops
    Are you using SSD or SAN / NAS based storage solution and sporadically observe SQL Server experiencing high IO wait times or from time to time your DAS / HDD becomes very slow according to SQL Server statistics? Read on… I need your help to up vote my connect item – https://connect.microsoft.com/SQLServer/feedback/details/744650/sql-server-io-handling-mechanism-can-be-severely-affected-by-high-cpu-usage. Instead of taking few seconds, queries could take minutes/hours to complete when CPU is busy.In SQL Server when a query / request needs to read data that is not in data cache or when the request has to write to disk, like transaction log records, the request / task will queue up the IO operation and wait for it to complete (task in suspended state, this wait time is the resource wait time). When the IO operation is complete, the task will be queued to run on the CPU. If the CPU is busy executing other tasks, this task will wait (task in runnable state) until other tasks in the queue either complete or get suspended due to waits or exhaust their quantum of 4ms (this is the signal wait time, which along with resource wait time will increase the overall wait time). When the CPU becomes free, the task will finally be run on the CPU (task in running state).The signal wait time can be up to 4ms per runnable task, this is by design. So if a CPU has 5 runnable tasks in the queue, then this query after the resource becomes available might wait up to a maximum of 5 X 4ms = 20ms in the runnable state (normally less as other tasks might not use the full quantum).In case the CPU usage is high, let’s say many CPU intensive queries are running on the instance, there is a possibility that the IO operations that are completed at the Hardware and Operating System level are not yet processed by SQL Server, keeping the task in the resource wait state for longer than necessary. In case of an SSD, the IO operation might even complete in less than a millisecond, but it might take SQL Server 100s of milliseconds, for instance, to process the completed IO operation. For example, let’s say you have a user inserting 500 rows in individual transactions. When the transaction log is on an SSD or battery backed up controller that has write cache enabled, all of these inserts will complete in 100 to 200ms. With a CPU intensive parallel query executing across all CPU cores, the same inserts might take minutes to complete. WRITELOG wait time will be very high in this case (both under sys.dm_io_virtual_file_stats and sys.dm_os_wait_stats). In addition you will notice a large number of WAITELOG waits since log records are written by LOG WRITER and hence very high signal_wait_time_ms leading to more query delays. However, Performance Monitor Counter, PhysicalDisk, Avg. Disk sec/Write will report very low latency times.Such delayed IO handling also occurs to read operations with artificially very high PAGEIOLATCH_SH wait time (with number of PAGEIOLATCH_SH waits remaining the same). This problem will manifest more and more as customers start using SSD based storage for SQL Server, since they drive the CPU usage to the limits with faster IOs. We have a few workarounds for specific scenarios, but we think Microsoft should resolve this issue at the product level. We have a connect item open – https://connect.microsoft.com/SQLServer/feedback/details/744650/sql-server-io-handling-mechanism-can-be-severely-affected-by-high-cpu-usage - (with example scripts) to reproduce this behavior, please up vote the item so the issue will be addressed by the SQL Server product team soon.Thanks for your help and best regards,Ramesh MeyyappanHome: www.sqlworkshops.comLinkedIn: http://at.linkedin.com/in/rmeyyappan

  • Facebook App EULA & Restrictions: What can't they do that my web app can?

    - by Adam Tannon
    I have written a nifty little web app (in Java/GWT/JS) and have been experimenting with the idea of making it available through Facebook as a Facebook App as well. After spending some time reading Facebook's developer docs, it seems like I can just create a Facebook App to point at any URL I want and use that as the app/canvas. It accomplishes this via iframes. So, my tentative plan is to just point it towards my (existing) web app so that I don't have to totally re-write it. But then that got me thinking: Facebook must regulate what sorts of things can be done through a Facebook App, vs. what an app can't do. For instance, I can't imagine I can point a Facebook App to point at a URL for a web app that accepts e-commerce payments (that would by-pass Facebook altogether and not allow them to take a cut from the ecom transaction!). Also, I can't imagine that Facebook allows developers to point their Facebook Apps to just any old URL without some sort of a scan, otherwise that would open Facebook up to the horrors of every security threat knownst to humanity. I know for a fact that when you write an iOS native app and put it up on the Apple App Store, that Apple actually scans your source code for violations of their EULA. So my question: does Facebook do the same? If so, what are their terms & conditions for what a Facebook app can/can't do? Suprisingly, I can't find this anywhere!! Thanks in advance!

  • Is my project a web site or a mobile app?

    I am a web developer. I have been developing web sites professionally for 15+ years using ColdFusion, SQL Server, and jQuery. I am doing a project for a client that uses the above technologies. The site has a mobile facet too. For that, I am using jQuery Mobile. The site enables retail store personnel to gather a store customer's preferences using any smart phone or tablet. The store personnel just needs to access a special link via a QR code and a login. Anyone can easily access the site from a PC's browser, too. Some sources suggest that mobile apps must be downloaded and installed using a third party, such as from Google, Amazon, or Apple. Others sources suggest that any information designed for use on mobile device is a mobile app. Regarding the site that is specifically designed for use by mobile devices that extensively uses jQuery Mobile, is this a "web site" or a "mobile app"? What is the "proper" description for this type of site? My customer insists that it is one and not the other. I insist that it is the other and not the one. Can you help me clarify this?

  • Web hosting deciding to pay for hosting or host your own?

    - by pllee
    Is there a guide out there on how to choose when to pay for web hosting vs. hosting your own? Assuming that root access is a must I would like to compare things like cost, scalability and personal stress. Here is what I could come up with. Paying for web hosting: Benefits: Much cheaper for a small scale. I assume anything under $50 a month would be cheaper than paying for the bandwidth of hosting. No stress in dealing with power outages, server restarts or internet going down. For the most part less busy work involved with setting up. Negatives: Cost goes way up when higher specs are needed (for example monthly cost triples with ability to use 8gb of ram that you can buy for $90 ). This means you have to target a particular ram usage and monitor so your instance stays within the threshold. root access for the most part is a premium. You may get tied into a vendor specific deployment process. Hosting on own : Positives: 100% control of specs and software. When you get past paying for the bandwidth you get much more bang for your buck by building your own machine. Negatives: Doesn't make financial sense if bandwidth costs are more than web hosting costs. Having to deal with power outages, server restarts or internet going down. I think the best of both worlds would be if there was a place that dealt with bandwidth, power outages and server restarts but you provided your own server. Kind of like a 24 hour day care for a server. Does anything like that exist?

  • Instalar SQL Server 2008

    - by Jason Ulloa
    En este post trataré de explicar los pasos para la instalación de SQL y su posterior configuración. Primer paso: Instalación de las reglas de Soporte (Setup Support Rules) Está será la primer pantalla de instalación con la que nos toparemos cuando tratemos de instalar sql server. En ella, únicamente debemos dar clic en siguiente(next). Paso 2: Selección de las características de instalación de SQL Server (Feature Selection) Este es a mi parecer el paso mas importante del proceso de instalación de SQL, pues es el que nos permitirá seleccionar todos los componentes que este tendrá posteriormente Acá lo importante es: Servicios de bases de datos y herramientas de administración. Todas las demás son plus del motor.   Paso 3: Configuración de la Instancia En este paso, no debemos preocuparnos por nada. Únicamente presionamos siguiente. Paso 4: Requerimientos de espacio en disco Nuevamente en esta instancia no tendremos trabajo alguno. Únicamente es una pantalla informativa de SQL en donde se muestra el espacio actual del disco y el espacio que la instalación de SQL Server consumirá. Presionamos siguiente (next). Paso 5: Configuración del servidor Este paso es uno de los mas importantes, pues en el le indicaremos a SQL que usuario utilizará para autenticarse y levantar cada uno de los servicios que hayamos seleccionado al inicio. Generalmente cuando se trabaja en local el usuario NT AUTHORITY\SYSTEM es la mejor opción. Si en este paso, seleccionamos un usuario con permisos insuficientes SQL nos dará un error. Presionamos siguiente (next) Paso 6: Configuración del motor de bases de datos En este paso, nos enfocaremos en la pestaña Account Provisioning, que será en la que le indiquemos el usuario con el que el motor de bases de datos funcionará por defecto. Lo mas recomendado sería hacer clic en la opción add current user, la cual agregará el usuario de windows  que se encuentre en ese momento. También, podremos seleccionar si queremos el modo de autenticación de SQL o el modo Mixto, que incluye autenticación de SQL Server y Windows. Para nuestra instalación seleccionaremos unicamente modo de autenticación de SQL. Una vez que agregamos el usuario presionamos siguiente (next) Paso 7:  Finalizar la configuración Luego de los pasos anteriores, las demás pantallas no requieren nada especial. Únicamente presionar siguiente y esperar a que la instalación de SQL termine.

  • Tellago announces SQL Server 2008 R2 BI quick adoption programs

    - by Vishal
    During the last year, we (Tellago) have been involved in various business intelligence initiatives that leverage some emerging BI techniques such as self-service BI or complex event processing (CEP). Specifically, in the last few months, we have partnered with Microsoft to deliver a series of events across the country where we present the different technologies of the SQL Server 2008 R2 BI stack such as PowerPivot, StreamInsight, Ad-Hoc Reporting and Master Data Services. As part of those events, we try to go beyond the traditional technology presentation and provide a series of best practices and lessons we have learned on real world BI projects that leverage these technologies. Now that SQL Server 2008 R2 has been released to manufacturing, we have launched a series of quick adoption programs that are designed to help customers understand how they can embrace the newest additions to Microsoft's BI stack as part of their IT initiatives. The programs are also designed to help customers understand how the new SQL Server features interact with established technologies such as SQL Server Analysis Services or SQL Server Integration Services. We try to keep these adoption programs very practical by doing a lot of prototyping and design sessions that will give our customers a practical glimpse of the capabilities of the technologies and how they can fit in their enterprise architecture roadmap. Here is our official announcement (you can blame my business partner, BI enthusiast, and Tellago's CEO Elizabeth Redding for the marketing pitch ;)): Tellago Marks Microsoft's SQL Server 2008 R2 Launch With Business Intelligence Quick Adoption Program Microsoft launched SQL Server 2008 R2 last week, which delivers several breakthrough business intelligence (BI) capabilities that enable organizations to:  Efficiently process, analyze and mine data Improve IT and developer efficiency Enable highly scalable and well-managed Business Intelligence on a self-service basis for business users The release offers a new feature called PowerPivot, which enables self service BI through connecting business users directly to enterprise data sources and providing improved reporting and analytics. The release also offers Master Data Management which helps enterprises centrally manage critical data assets company-wide and across diverse systems, enabling increased integrity of information over time. Finally, the release includes StreamInsight, which is a framework for implementing Complex Event Processing (CEP) applications on the Microsoft platform. With StreamInsight, IT organizations can implement the infrastructure to process a large volume of events near real time, execute continuous queries against event streams and enable real time business intelligence. As a thought leader in the Business Intelligence community, Tellago has recognized the occasion by launching a series of quick adoption programs to enable the adoption of this new BI technology stack in your enterprise. Our Quick Adoption programs are designed to help you: Brainstorm BI solution options  Architect initial infrastructure components Prototype key features of a solution As a 2-3 day program, our approach is more efficient and cost effective than a traditional Proof of Concept because it allows you to understand the new SQL Server 2008 R2 feature set  while seeing directly how you can leverage it for your business intelligence needs. If you are interested in learning more about the BI capabilities of Microsoft's Business Intelligence stack, including SQL Server 2008 R2, we can help.  As industry experts and software content advisers to Microsoft, Tellago is the place where ideas meet technology expertise.  Let us help you see for yourself the advantages that you can gain from Microsoft's  SQL Server 2008 R2.

  • SQL Injection - some sense at last!

    - by TATWORTH
    I see various articles that proclaim means to guard against SQL injection. As individual steps they are of use but since they were often proclaimed as "the solution" they were potentially misleading. At http://www.simple-talk.com/sql/learn-sql-server/sql-injection-defense-in-depth/ there is an article entitled "SQL Injection: Defense in Depth" - this article argues what I have argued myself. Remember that however low-grade the information on your web site is, if your site is hacked, the public may percive the hacking as your most sensitive information was exposed.

  • PL/SQL to delete invalid data from token Strings

    - by Jie Chen
    Previous article describes how to delete the duplicated values from token string in bulk mode. This one extends it and shows the way to delete invalid data. Scenario Support we have page_two and manufacturers tables in database and the table DDL is: SQL> desc page_two; Name NULL? TYPE ----------------------------------------- -------- ------------------------ MULTILIST04 VARCHAR2(765) SQL> SQL> desc manufacturers; Name NULL? TYPE ----------------------------------------- -------- ------ ID NOT NULL NUMBER NAME VARCHAR In table page_two, column multilist04 stores a token string splitted with common. Each token represent a valid ID in manufacturers table. My expectation is to delete invalid token strings from page_two.multilist04, which have no mapping id in manufacturers.id. For example in below SQL result: ,6295728,33,6295729,6295730,6295731,22, , value 33 and 22 are invalid data because there is no ID equals to 33 or 22 in manufacturers table. So I need to delete 33 and 22. SQL> col rowid format a20; SQL> col multilist04 format a50; SQL> select rowid, multilist04 from page_two; ROWID MULTILIST04 -------------------- -------------------------------------------------- AAB+UrADfAAAAhUAAI ,6295728,6295729,6295730,6295731, AAB+UrADfAAAAhUAAJ ,1111,6295728,6295729,6295730,6295731, AAB+UrADfAAAAhUAAK ,6295728,111,6295729,6295730,6295731, AAB+UrADfAAAAhUAAL ,6295728,6295729,6295730,6295731,22, AAB+UrADfAAAAhUAAM ,6295728,33,6295729,6295730,6295731,22, SQL> select id, encode_name from manufacturers where id in (1111,11,22,33); No rows selected SQL> Solution As there is no existing SPLIT function or related in PL/SQL, I should program it by myself. I code Split intermediate function which is used to get the token value between current splitter and next splitter. Next program is main entry point, it get each column value from page_two.multilist04, process each row based on cursor. When it get each multilist04 value, it uses above Split function to get each token string stored to singValue variant, then check if it exists in manufacturers.id. If not found, set fixFlag to 1, pending to be deleted.

  • Online SQL course [closed]

    - by Sualeh Fatehi
    Does anyone know of a free online SQL source that allows you to practice SQL online without installing a database? Sort of like Code Academy? I am looking to start teaching SQL to a remote audience, and I want to be able to set up a schema and some data, and have the students run SQL against my schema, and practice. I also want a way to set up some exercises for them. In short, a Code Academy kind of environment for SQL.
