  • Execution plan issue requires reset on SQL Server 2005, how to determine cause?

    - by Tony Brandner
    We have a web application that delivers training to thousands of corporate students running on top of SQL Server 2005. Recently, we started seeing that a single specific query in the application went from 1 second to about 30 seconds in terms of execution time. The application started throwing timeouts in that area. Our first thought was that we may have incorrect indexes, so we reviewed the tables and indexes. However, similar queries elsewhere in the application also run quickly. Reviewing the indexes showed us that they were configured as expected. We were able to narrow it down to a single query, not a stored procedure. Running this query in SQL Studio also runs quickly. We tried running the application in a different server environment. So a different web server with the same query, parameters and database. The query still ran slow. The query is a fairly large one related to determining a student's current list of training. It includes joins and left joins on a dozen tables and subqueries. A few of the tables are fairly large (hundreds of thousands of rows) and some of the other tables are small lookup tables. The query uses a grouping clause and a few where conditions. A few of the tables are quite active and the contents change often but the volume of added rows doesn't seem extreme. These symptoms led us to consider the execution plan. First off, as soon as we reset the execution plan cache with the SQL command 'DBCC FREEPROCCACHE', the problem went away. Unfortunately, the problem started to reoccur within a few days. The problem has continued to plague us for awhile now. It's usually the same query, but we did appear to see the problem occur in another single query recently. It happens enough to be a nuisance. We're having a heck of a time trying to fix it since we can't reproduce it in any other environment other than production. I have downloaded the High Availability guide from Red Gate and I read up more on execution plans. I hope to run the profiler on the live server, but I'm a bit concerned about impact. I would like to ask - what is the best way to figure out what is triggering this problem? Has anyone else seen this same issue?

  • Does this video card support sound?

    - by Macros
    Probably a rookie question but here goes...I am looking to buy a new video card for a few year old PC which will be used as a media centre. The card I am looking at is this one http://www.ebuyer.com/product/173708, with the main aim being to play blu-ray films. In the product description it states that the card has 7.1 audio channel support, does this mean it will play the sound from the blu-ray through the HDMI, or do I need a separate sound card?

    - by Andrew
    This question already has an answer here: How many files can a windows folder contain? 1 answer I am running Windows XP Professional, service pack 3. Right now I have 4,398 files in a single folder, and Windows XP seems to read it fine. How many more files can I place in this same folder, either theoretically or practically? Thanks for your time.

  • IIS 7 - allow http for part of site, https for rest?

    - by Martin Clarke
    In IIS 7, is there a way to set two urls on the same site to allow http and https, and the rest to be https only? - http://mysite/url1 or https://mysite/url1 is accepted and stays on that protocol. - http://mysite/url2 or https://mysite/url2 is accepted and stays on that protocol. - any other item, i.e. http://mysite/whatever redirects to https://mysite/whatever - https://mysite/whatever is accepted. Edited because first question wasn't clear enough.

  • Copying info from the device manager to the clipboard

    - by user12816
    I have a Logitech webcam, which I can plug into my Windows XP machine via USB. When I open the Device Manager, I can select the webcam and choose Properties--Driver--Driver Details. This gives me the following list of driver filenames: C:\Program Files\Common Files\logishrd\WUApp32.exe [25 more filenames...] C:\WINDOWS\TWAIN_32\QuickCam\reset.wav My question is, is there any way to copy this list to the clipboard? Copying it by hand is a drag.

  • Adding additional locations to Office 2013 save "Places"

    - by Paperjam
    When saving a document in Office, you are given the option of saving locally or to your SkyDrive account. Presumably, it's possible to add additional locations to this menu (Dropbox, etc.). Is this possible in the Live Preview, and how does one accomplish this? Edit: when I asked this question, I was not logged into a Live account. I have since logged in and discovered services may be added to the logged-in account, however Dropbox (and non-MS services) are not offered. Account settings:

  • Lighttpd Prepending Strings to Certain Files.

    - by Kyle
    I have a Mint install (Fantastic stats, if you were wondering) and I would like to move over to Lighttpd for my server needs. Unfortunatly, this means that php_auto_prepend is no longer easily available. I understand that PHP can do this in the php.ini file, but I have areas that can't have this value prepended so that's out of the question. Is there a lighttpd way to prepend my script for my mint install in some files, and have it disabled for others?

  • Songbird 4-pane filter panel library view

    - by wonea
    I love Songbird but I was already whether it's possible add an additional column to the Songbird layout, I love categorising my music by dates as well, and find right clicking above the column header to change a little to messy and want even more flexibility. So here's my mockup of the 4-pane panel library, I think I've made Songbird do this by mistake in the past through a bug. Question is, is this possible?

  • Using Dropbox as a cloud based file share - does everyone need an upgraded account?

    - by aSkywalker
    We have a file share in our small office (3-5 users). We now have the need for the files to be accessible outside of the office. I like the idea of dropbox - we have been using it for small remote sharing. If we buy the upgrade account, and move 30 to 70 gigs of files to it, will every user have to have the pro account? I have submitted this question to dropbox - but thought that the advice of users here would also be valuable

  • Data Sources (ODBC) hangs when trying to create a new database connection

    - by FredrikD
    When I try to create a new database connection, the Data Sources (ODBC) programs hangs or takes a very long time to find the list of available SQL Servers. This only happens when there are other computers on the network, when my machine (a standard Windows 7 laptop) is alone, it works just fine. My question is: What should I look for in terms of SQL server or ODBC configurations that will take away this random behaviour?

    - by Sam007
    I am trying to add a response header to the Jetty configuration the following command, Access-Control-Allow-Origin: * Ok so this Jetty webserver is the base on which Geoserver is running.

I wish to add this response to the header to remove the error Unable to load XMLHttpRequest I wish to know that under which tags should I wrap this response header and where in the file should I save it.

  • Exchange ActiveSync is not working with Android's 'verify certificate' setting, what do I need to do to make them work together?

    - by Yannone
    All other methods of Activesync and web access to my Exchange server are working fine with no errors or issues, but when we attempt to configure Android phones for the server, it will only work with 'verify certificate' checked off. Ideally, I'd like my users to be able to use the default configuration, which includes the 'Verify Certificate' option. My primary question is: 'What does Verify Certificate do?', as I imagine if I knew that, I might have some idea why it isn't working.

    - by Alan
    Hello, after a lovely blue screen my vista 64 machine decided to reconfigure one of my drives to no longer be part of my raid volume. So now my raid fails as it only has one member disk. This happened to me about 6 months ago and I just changed the disk in question back to a raid disk and all was well. However I cant seem to find that option in my bios or raid config anymore :( Any help would be appreciated

  • Sql Server huge tables with no rows

    - by Mike Gates
    I have a Sql Server database that has a few tables with zero row count but take up a combined 10 GB of space. I can see this by doing right-click/properties on the tables in question (data space is huge, between 1 and 6 GB, and row count is zero on these tables). I have no clue what could be causing this as I would assume zero rows would mean nearly zero space taken. Any ideas?

  • DVD (vob file) to online video viewer?

    - by Nick
    I've been sent a DVD which needs to be put onto a website, but I honestly don't even know where to start. Do I simply convert the file using some software to MP4(?!) and then use something like http://videojs.com/ to view it online? I'm really sorry for the vague question, but I want to produce the best quality results, with good compression, good quality and a nice video player interface. Would really appreciate any recommendations. Thank you!

  • Dedicated Hosting offering Intel Core 2 Quad @ 6GHz. Is this real?

    - by Daniel Magliola
    Hi, sorry if this is a very dumb question, but... I just got an offer from a dedicated hosting company, offering me a box with "2 Core 2 Quad processors @ 6GHz" I didn't know we could get 6GHz, and some googling turned out a bunch of people getting that, after overclocking like crazy, which seems to confirm my suspicion. Are there hostings offering 6GHz CPUs, or are these people outright lying to me? Thank you!

  • Using ssd intensively. Should we worry?

    - by vvavepacket
    I'm currently using conventional HDDs like the 5200 rpms, browsing a lot, my folder and files are scattered, torrenting always and I'm not fond of optimization like disabling cache, cleaning temp Files , etc. My question is, given the above conditions (no disable of cache, seeding always in torrent, downloading torrent) is it safe to use SSD? I'm pretty worried about cycles but I read an article wherein it says its safe since it will usually wear out for 10 years given that you always write heavily and continuously. Thanks
