• What to monitor on MSSQL Server

  - by user361434

  Hi all I have been asked to monitor MSSQL Server (2005 & 2008) and am wondering what are good metrics to look at? I can access WMI counters but am slightly lost as to how much depth is going to be useful. Currently I have on my list: user connections logins per second latch waits per second total latch wait time dead locks per second errors per second Log and data file sizes I am looking to be able to monitor values that will indicate a degradation of performance on the machine or a potential serious issue. To this end I am also wondering at what values some of these things would be considered normal vs problematic? As I reckon it would probably be a really good question to have answered for the general community I thought i'd court some of you DBA experts out there (I am certainly not one of them!) Apologies if a rather open ended question. Ry

• Events raised by BackgroundWorker not executed on expected thread

  - by Topdown

  A winforms dialog is using BackgroundWorker to perform some asynchronous operations with significant success. On occasion, the async process being run by the background worker will need to raise events to the winforms app for user response (a message that asks the user if they wish to cancel), the response of which captured in an CancelEventArgs type of the event. Being an implementation of threading, I would have expected the RaiseEvent of the worker to fire, and then the worker would continue, hence requiring me to pause the worker until the response is received. Instead however, the worker is held to wait for the code executed by the raise event to complete. It seems like method I am calling via the event call is actually on the worker thread used by the background worker, and I am surprised, since I expected to see it on the Main Thread which is where the mainform is running. Also surprisingly, there are no cross thread exceptions thrown. Can somebody please explain why this is not as I expect?

• Anyone realize success using Apple Mac OS 10.6 and Parallels 5 for a Visual Studio Dev machine?

  - by Buffalo

  Greetings my wonderful StackOverflow family :) I grew up using Windows and switched to OSX as a Computer Science major in College. I've recently started my first real software developer job, and have a ThinkPad and Windows XP for developing ASP.NET / MS SQL applications (Visual Studio 2008). Question: Basically, I am wondering if any developers out there have had real success creating ASP.NET applications on a Mac using a VM? I've been fighting with Parallels 5 all week and finally have Windows 7 and VS 2008 running but my hot-keys are all screwed up. Is it worth the work to keep beating this thing into submission? Should I give up? Should I give Mono a try instead? Thanks Folks, I can't wait to see what you all think!

• Quick methodology to show client a working demo

  - by LordCover

  I am not starting an argumentative discussion here and this post is not about career development, but from the commercial point of view: If a company was using ASP.Net MVC as a main methodology to build their web sites and application. However, ASP.Net MVC takes more time to show a functional application than ASP.Net Web Forms, for example, building domain models would take some time which obviously can't be represented on a UI at that current stage. My question is, if a client wants to see a functional demo application (just a proof of concept) so he knows that the company he is dealing with is professional and capable of doing that. Would it be better to do that demo in ASP.Net Web Forms only to show the client, and then work on the real application using ASP.Net MVC? If not, what are the (quick) alternatives?, I mean, if we tell the client to wait till we have a working demo (by ASP.Net MVC) we may lose the client and the whole project opportunity.

Can I make progressdialog to be shown while the black screen is displayed??

• stub webserver for integration testing

  - by Frank Schwieterman

  I have some integration tests where I want to verify certain requires are made against a third-[arty webserver. I was thinking I would replace the third-party server with a stub server that simply logs calls made to it. The calls do not need to succeed, but I do need a record of the requests made (mainly just the path+querystring). I was considering just using IIS for this. I could 1) set up an empty site, 2) modify the system's host file to redirect requests to that site 3) parse the log file at the end of each test. This is problematic as for IIS the log files are not written to immediately, and the files are written to continuosly. I'll need to locate the file, read the contents before the test, wait a nondeterministic amount of time after the test, read the update contents, etc. Can someone think of a simpler way?

• jQuery Audio Player

  - by tony noriega

  I was given 2 MP3 files, one that is 4.5Mb and one that is 5.6Mb. I was instructed to have them play on a website i am managing. I have found a nice, clean looking CSS based jQuery audio player. My question is, is this the right solution for files that big? I am not sure if the player preloads the file, or streams it ? (if that is the correct terminology) i dont deal much with audio players and such... this player is from happyworm.com/jquery/jplayer/latest/demo-01.htm is there another approach i shoudl take to get this to play properly? I dont want it to have to buffer, and the visitor to wait, or slow page loading...etc..etc.. i want it to play clean and not affect the visitors session to the site. thanks

• ArrayBlockingQueue - How to "interrupt" a thread that is wating on .take() method

  - by bernhard

  I use an ArrayBlockingQueue in my code. Clients will wait untill an element becomes available: myBlockingQueue.take(); How can I "shutdown" my service in case no elements are present in the queue and the take() ist wating indefenitely for an element to become available? This method throws an InterruptedException. My question is, how can I "evoke" an Interrupted Exception so that take() will quit? (I also tought about notify(), but it seems I doesnt help here..) I know I could insert an special "EOF/QUIT" marker Element but is this really the only solution? UPDATE (regarding the comment, that points to another question with two solutions: one mentioned above using a "Poisoning Pill Object" and the second one is Thread.interrupt(): The myBlockingQueue.take() is used NOT in a Thread (extending Thread) but rather implements Runnable. It seems a Runnable does not provide the .interrupt() method? How could I interrupt the Runnable? Million Thanks Bernhard

  I want to perform asynchronous JavaScript downloads of two files that have dependencies attached to them. function addScript(url) { var script = document.createElement('script'); script.src = url; document.getElementsByTagName('head')[0].appendChild(script); } addScript('http://google.com/gmaps.js'); addScript('http://jquery.com/jquery.js'); function requiresJQuery() { ... } function requiresGmaps() { ... } function requiresBothJQueryGmaps() { ... } // do some work that has no dependencies on either JQuery or Google maps ... // now call a function that requires Gmaps to be loaded if (GmapsIsLoaded) { requiresGmaps(); } // then do something that requires both JQuery & Gmaps (or wait until they are loaded) if (JQueryAndGmapsIsLoaded) { requiresBothJQueryGmaps(); } Question: How can I create an event to indicate when: JQuery is loaded? Google Maps is loaded JQuery & Google Maps are both loaded?

• Qt compilation and stylesheet

  - by Yosko

  Each time I compile my Qt project after modifying my qss stylesheet file, the modifications aren't taken into account, unless I rebuild everything. Any idea on a workaround for this, so that I don't have to wait 5 minutes each time I change my qss ? Notes: I use Qt 4.8, and my stylsheet is declared in a resource file (qrc). EDIT: As suggested by Luca Carlon, when a qss is reference in the project through a .qrc file, the changes in the qss don't affect the qrc, and the compiler ignores it. To avoid that, I added a Custom Build Step to my project: before the qmake step! calls a .bat file without any argument the .bat contains the real command copy /b files.qrc +,,

• Soundpool sample not ready

  - by SteD

  I have a .wav file that I'd like to use across my game, currently I am loading the sound in onCreate() of each activity in the game. soundCount = soundpool.load(this,R.raw.count, 1); The sound will be played once the activity starts. soundpool.play(soundCount, 0.9f, 0.9f, 1, -1, 1f); Problem is at times I will hit the error "sample x not ready". Is it possible to load the .wav file once upon starting the game and keep it in memory and use it later across the game? Or is it possible to wait for 1-2 seconds for the sound to load finish?

• I cannot fetch appointments immediately via EWS on exchange server

  - by DappleHou

  I developed a transport agent for exchange server. In this agent, I code to invoke EWS to get appointments. I cannot get appointments immediately by the code. wait for a while, then go to get appointments again. This time, its OK. Why not immediately? Here is my code. To solve it, I have to get appointments repeatedly till find appointments. do{ webServiceData.FindItemsResults<webServiceData.Appointment> results = folder.FindAppointments(view); Thread.sleep(100); }while(results.Items.Count==0); Note that the code is inside transport agent. Is there any other solutions?

• Keep an ASP.NET IIS website responsive when time between visits is long

  - by Abel

  After years of ASP.NET development I'm actually quite surprised that I can't seem to find a satisfying solution for this. Why does an IIS ASP.NET site always seem to fall asleep (for 2-6 seconds) after a certain time of inactivity (after several hours), during which no HTTP response is sent from server to client. This happens on any type of site, one page or many, db or not, regardless the settings. How can I fix this? During the wait time, the server is not busy and there are no high peaks or (.NET) memory shortages. My guess is, it has to do with Windows moving the IIS process to the background and its memory to the page file, but I'm not sure. Anybody any idea? EDIT: one solution is to send some HTTP request once an hour or so, but I hope for something more constructive. EDIT: what I meant is: after hours of inactivity, it pauses several seconds on any new HTTP request.

• SQL Server Command Timeouts Timeout expired. The timeout period elapsed prior to completion of the o

  - by user104295

  Hi there, we've had a ASP.NET web application deployed for a number of years now.... last week we migrated to a slightly slower server to save some money. Now we're frequently getting command timeouts: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding This is understandable in that a slower server will take longer to produce results; take longer time and produce a timeout. Is there any system-wide way to get SqlClient to set a longer timeout? We cannot change the code, as it's everywhere... we're using multiple data access technologies as well. Maybe there's a default command timeout setting on a connection string? We just need to increase it by 30 seconds; we're happy to wait a bit longer for queries to return. thanks

• Computer sending data while turned of

  - by Nicklas Ansman

  I have a some what strange problem (which could have and easy and obvious solution for all I know). My problem is that when I've booted ubuntu (now 10.4 but same problem with 9.10) and turns it off it starts sending a HUGE amount of data via the ethernet cable, so much in fact that my router can't handle it and stops responding. As far as I can tell the computer is completely turned off with no fans spinning. I can add that if I boot windows I do not have this problem, just when exiting ubuntu. There are two "fixes" for my problem: Pull the ethernet cable until the next boot Turn off power to the PSU and wait for the capacitors to unload Is there anyone who knows what could be going on? I'd be happy to post some logs or conf-files. Currently I'm using the ethernet port on my motherboard which is a Asus P6T Deluxe V2 with an updated version of the BIOS (maybe not the latest but since it only happens when I've been in ubuntu I don't wanna mess with the BIOS too much). Regards Nicklas

• Netlink user-space and kernel-space communication

  - by sasayins

  Hi, I am learning programming in embedded systems using Linux as my main platform. And I want to create a Device Event Management Service. This service is a user-space application/daemon that will detect if a connected hardware module triggered an event. But my problem is I don't know where should I start. I read about Netlink implementation for userspace-kernelspace communication and it seems its a good idea but not sure if it is the best solution. But I read that the UDEV device manager uses Netlink to wait a "uevent" from the kernel space but it is not clear for me how to do that. I read about polling sysfs but it seems it is not a good idea to poll filesystem. What do you think the implementation that should I use in my service? Should I use netlink(hard/no clue how to) or just polling the sysfs(not sure if it works)? Thanks

• Boolean Not operator in VBScript

  - by Lumi

  Consider the following two conditionals (involving bitwise comparisons) in VBScript: If 1 And 3 Then WScript.Echo "yes" Else WScript.Echo "no" If Not(1 And 3) Then WScript.Echo "yes" Else WScript.Echo "no" Prints first yes, then no, right? cscript not.vbs Wrong! It prints yes twice! Wait a second, the Not operator is supposed to perform logical negation on an expression. The logical negation of true is false, as far as I know. Must I conclude that it doesn't live up to that promise? How and why and what is going on here? What is the rationale, if any?

• Test if current page is inside a shadowbox? (so i can close the shadowbox and reopen that page in t

  - by Max Williams

  Hi all I have a couple of pages in my site which open in a shadowbox window rather than the main window. My problem is that if the user session expires, then the user clicks on one of the links that open in a shadowbox, they are redirected to the login page INSIDE THE SHADOWBOX, which i don't want. I've been trying to think of the best way to handle this - one way i thought of, which seems a bit clumsy tbh, was on the login page to test if we're in a shadowbox, and if we are then close it and redirect the parent window to the login page. a) does this seem like a sensible plan? I added the following to my login page, which works: $(document).ready(function(){ if(window.parent.location != window.location){ window.parent.location.href = window.location; } } but i have to wait for the shadowbox to finish loading the page and then redirect. So it's working but like i say a bit clumsy. Is there a nicer way? grateful for any advice - max

• Unable to get multiple connection to MySql on Windows 7

  - by Hussain

  I have installed MySql on windows 7 ... issue is i'm unable to get multiple connection to MySql . If I connect to MySql through command line and at the same time open an other MySql command line client it goes into wait state, as soon as I disconnect the first one later one gets connected. Because of above issues I'm unable to run tomcat in debug mode as it tries to get more than one connection to MySql in debug mode. Previously I was using same version of MySql i.e. 5.1 on vista and it was working fine.

• Too slow gwt develpment mode !

  - by Ehsan Khodarahmi

  I'm using eclipse galileo with latest GWT 2.0 version in development mode, but it runs really slow (i should wait about 1 minute to open one page, but after compilation, my application works very well when I run it using tomcat 5.5). My code is not too heavy & i guess there is an os-related or software inconsistency problem, because I'd this problem before, but when i reinstalled my windows vista sp2 (I formatted my windows drive & reinstalled it), my problem solved for just some days & then again it became to slow ! I didn't install any special software on my windows, so i really dont know why this problem occures ??? any suggestion ?

• PHP Launch Execute Files Concurrently

  - by Ozzy

  Hi all. Basically, I was doing some testing using apache bench. The file i was testing takes 2 seconds to execute (its optimised, it connects to an external server hence the slowdown) Basically I found that the more concurrent useres i emulated, the more executions of the file i could do per second. Is there anyway that i can do something like this in php? : <?php execute_file('file.php'); execute_file('file.php'); execute_file('file.php'); execute_file('file.php'); execute_file('file.php'); ?> That would execute the file 5 times but would NOT wait for the files to finish downloading so the above example would quickly call the 5 functions then exit. Im assuming somesort of timeout would be used?

• Using WINAPI ReadConsole

  - by Jim Fell

  I am trying to use the WINAPI ReadConsole() to wait for any keypress at the end of my Win32 console application. CONSOLE_READCONSOLE_CONTROL tControl; char pStr[65536]; DWORD dwBufLen = 1; DWORD dwCtl; tControl_c.nLength = sizeof( CONSOLE_READCONSOLE_CONTROL ); tControl_c.nInitialChars = 0; tControl_c.dwControlKeyState = 0; tControl_c.dwCtrlWakeupMask = NULL; pBuf[0] = 0x00; do { ReadConsole( hConsole_c, pStr, (*pBufLen) * sizeof(TCHAR), pBufLen, &tControl ); } while ( pStr[0] == 0x00 ); The code executes without throwing an exception. However, when the ReadConsole() function executes the error code ERROR_INVALID_HANDLE (0x06) is flagged. I have verified hConsole_c to be a valid handle. Does anyone have any insight as to what I am doing wrongly? I am using Visual C++ 2008 Express Edition. Thanks.

• Best Practice of Field Collapsing in SOLR 1.4

  - by Dominik

  I need a way to collapse duplicate (defined in terms of a string field with an id) results in solr. I know that such a feature is comming in the next version (1.5), but I can't wait for that. What would be the best way to remove duplicates using the current stable version 1.4? Given that finding duplicates in my case is really easy (comparison of a string field), should it be a Filter, should I overwrite the existing SearchComponent or write a new Component, or use some external libraries like carrot2? The overall result count should reflect the shortened result.
