  • Strange Jmeter connection refuse on Tomcat

    - by Tommy
    I tried difference setting in Jmeter and Tomcat. If the Threads number in JMeter is 1~200, Then tomcat is okay. If It is 300, Then after serving few requests, tomcat starts to output errors. Here is the error show in JMeter java.net.ConnectException: Connection refused: connect at java.net.PlainSocketImpl.socketConnect(Native Method) at java.net.PlainSocketImpl.doConnect(Unknown Source) at java.net.PlainSocketImpl.connectToAddress(Unknown Source) at java.net.PlainSocketImpl.connect(Unknown Source) at java.net.SocksSocketImpl.connect(Unknown Source) at java.net.Socket.connect(Unknown Source) at java.net.Socket.connect(Unknown Source) at sun.net.NetworkClient.doConnect(Unknown Source) at sun.net.www.http.HttpClient.openServer(Unknown Source) at sun.net.www.http.HttpClient.openServer(Unknown Source) at sun.net.www.http.HttpClient.<init>(Unknown Source) at sun.net.www.http.HttpClient.New(Unknown Source) at sun.net.www.http.HttpClient.New(Unknown Source) at sun.net.www.protocol.http.HttpURLConnection.getNewHttpClient(Unknown Source) at sun.net.www.protocol.http.HttpURLConnection.plainConnect(Unknown Source) at sun.net.www.protocol.http.HttpURLConnection.connect(Unknown Source) at org.apache.jmeter.protocol.http.sampler.HTTPJavaImpl.sample(HTTPJavaImpl.java:483) at org.apache.jmeter.protocol.http.sampler.HTTPSamplerProxy.sample(HTTPSamplerProxy.java:62) at org.apache.jmeter.protocol.http.sampler.HTTPSamplerBase.sample(HTTPSamplerBase.java:1018) at org.apache.jmeter.protocol.http.sampler.HTTPSamplerBase.sample(HTTPSamplerBase.java:1004) at org.apache.jmeter.threads.JMeterThread.process_sampler(JMeterThread.java:411) at org.apache.jmeter.threads.JMeterThread.run(JMeterThread.java:297) at java.lang.Thread.run(Unknown Source) My tomcat server.xml in eclipse <!--The connectors can use a shared executor, you can define one or more named thread pools--> <Executor name="tomcatThreadPool" namePrefix="catalina-exec-" maxThreads="2000" minSpareThreads="250" acceptCount="2000"/> <Connector executor="tomcatThreadPool" URIEncoding="UTF-8" connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443" /> Any idea why this is happening ?

  • tar fails to open .tar file on OS X

    - by denonth
    I need to unarchive a file to the /Developer folder. My file is in /Users/User/Desktop/VMware/Downloads And I am trying tar -xf qt-everywhere-ios-4.8.0-arm7-nossl.tar.gz -C /Developer and keep getting: Lions-Mac:Downloads User$ tar -xf qt-everywhere-ios-4.8.0-arm7-nossl.tar -C /Developer tar: Error opening archive: Failed to open 'qt-everywhere-ios-4.8.0-arm7-nossl.tar' How can I achieve this? Install Qt for iOS SDK The Qt for iOS SDK has been configured to be installed in the default Xcode installation location /Developer. It is not possible to install the SDK into another location without first rebuilding it, as the install location is contained within the qmake executable, and that is built as part of Qt. To install the Qt for iOS SDK, open ‘Terminal’ and type the following from the command­-line: tar –xf qt­-everywhere-­ios­-4.8.0­-xxx.tar.gz –C /Developer (where xxx is an identifier which can be used to determine the build of the iOS SDK eg. arm7-­-nossl) This will install the Qt for iOS SDK into the following path: /Developer/Platforms/iPhoneOS.platform/Developer/usr/share/qt­-everywhere­-ios­-4.8.0

  • Open Source webapp that shows PC / Projector status in 30+ Lecture rooms

    - by Seanchán
    I am looking for a simple web application that only has a simple graphical representation of the current status of 30+ lecture rooms. I.e. Green = good, Red=bad i.e. PC or Projector not working. With a little message and a ETA as well. I am not looking for monitoring software, merely a way for a tech to flag a room as "technically challenged" until 1PM or until "Friday 10AM". With a message for those lecturers who are interested: "Waiting on replacement bulb" or "Power supply gone" I know this is a simple thing to code up yourself, but I am looking for something that has been around for a few years that has some cool extra little functionality that you wouldn't think of yourself. I just can't find anything like that out there. And just to be clear: not monitoring software, more like lecturer feedback web app.

  • SSIS DSN Not Showing as ODBC Data Source

    - by user1114330
    I have been following the directions here: http://social.msdn.microsoft.com/Forums/en-US/sqlintegrationservices/thread/05ccd778-b78c-4a83-a10a-c4ae412cc6e4 And ran into a problem where my System DSN is not showing up as a ODBC provider. I found this which seemed promising: http://support.microsoft.com/kb/2000277 I was not able to delete the key but followed but I did what was suggested: "If unable to delete the key, double-click the key and erase the Data value entered. Once done, the value should read ' (value not set) '" However, after following the instructions my System DSN still does not appear as an option. The USER DSN however does show...has shown but does not work as I get a permissions error. Any ideas?

  • Why is port 444 open on this router?

    - by TJ Thind
    I have a Cisco RV110W. I ran nmap at it from the outside and nmap reports that the router has tcp port 444 open. Yet there are no port forwarding rules specifying this port. It should as far as I can tell, be closed. There's even a service listening to that port which I can connect to through telnet. I threw some SNPP commands at it but the service doesn't respond to any of them so I don't believe it's SNPP. Does anyone have any idea why this particular router has tcp port 444 open? I haven't been able to find anything in the manual or on Cisco's website.

  • Easiest way to open CSV with commas in Excel

    - by Borek
    CSV files are automatically associated with Excel but when I open them, all the rows are basically in the first column, like this: It's probably because when Excel thinks "comma-separated values", it actually searches for some other delimiter (I think it's semicolon but it's not important). Now when I have already opened this file in Excel, is there a button or something to tell it "reopen this file and use comma as a delimiter"? I know I can import the data into a new worksheet etc. but I'm asking specifically for a help with situation where I already have a CSV file with commas in it and I want to open it in Excel without creating new workbook or transforming the original file.

  • Troubleshooting source of heavy resource-usage on a windows server 2008 running multiple sites

    - by batman_man
    Hi, I am running about 10 asp.net websites on a hosted virtual server. The server runs Server 2008 - each website is backed by its own database running on SQL server 2008 on the same box. Lately the box has seemed really slow. The only kind of discovery i could think of doing was looking in the task manager, where i can see w3wp and sqlserver.exe jumping to 40% cpu usage every 5-10 seconds. What are the steps i can take to determine which of my websites is taking these resources and or what database is getting hit the most? I have of course ssms installed on the machine as well. As you can tell, my sysadmin skills are very very limited - any help would be much appreciated.

  • Use Web Browser (Google Chrome or Firefox) to Open Web Sites from a List in File

    - by MMA
    I have a (text) file containing a list of web site addresses. I know that I can open the file in an editor and then copy-paste the addresses to the browser address bar. That means, if I have ten addresses in that file, I will need ten copy-paste operations, which must be tedious. But is there a way to ask the browser (preferably Google Chrome or Firefox) to open all of them in one go in different tabs? I am using Ubuntu, if that is related in any way to the solution you provide.

  • securing source code with bitlocker

    - by Daniel Powell
    We need to deploy a web based application at a client site where it will be within their local intranet. Part of our requirement is to provide some basic security to protect our IP. I realise that nothings a 100% guaranteed fix but we are just looking to make it a bit harder for most people. The server will be running server 2008 and I was considering using bitlocker as a cheap and nasty way to protect it. From what I understand assuming the mobo supports it we can use the Transparent bitlocker mode and this means that moving the hdd to another pc will mean the hdd will be unreadable in that machine baring some sort of cold boot attack to steal the encryption keys. Is this assumption correct and in the case that the motherboard or any other component fails in the pc and we need to replace it do we lose access to our data or is there a way to unencrypt it (obviously accessible to only our company) EDIT: we do have legal documents that cover this and we will be locking the pc physically and the client will not have access to the pc (windows login) other than via the website we host on it

  • How to open existing VMs in VirtualBox?

    - by Alex R
    VirtualBox seems to lack the obvious "File - Open" menu option. Frustrating! More details... I recently got a new workstation and I moved my VirtualBox and VMWare Player VMs from the old PC to the new. The VMWare Player VMs are a snap... you go to "File - Open a Virtual Machine...", find the .vmx files from the old PC, and voila! It's up and running. All the required files apparently are in the same folder. With VirtualBox there just doesn't seem to be a way to do that. Looks like VMs are tied to the original host in some magical/invisible way like registry entries, etc.

  • Remote installation and configuration software, preferrably open source

    - by Brimstedt
    Hello, Im looking for some remote-installation software. I've looked briefly at unattended, opsi and a bunch of stuff, but there is nowhere near enough time to evaluate them all, and they are rather complex to setup so some insight would be very appreciated. This is foremost for windows clients, but linux support would be good. Something like apt-get would've been great. Requirements: Simple to setup and use Set up groups of users (developers, management, sales, etc) Chose which software to be installed for different groups Add new software to groups and it will be automatically installed on client Dependencies between software Nice-to-have: Linux client support OS-unattended installation thanks in advance

  • Use all 5.1 speakers with a 2.1 audio source

    - by thegreyspot
    Hi! I just bought a 5.1 surround sound speaker set for my computer in my bedroom. The rear speakers are next to me in bed while the front speakers are at the other end of the bed at my feet. While I enjoy the surround sound during movies that support 5.1 sound, I would like to have my rear speakers working when listening to podcasts, or other 2.1 channel sound. How can I do this? When I enable "Speaker Fill" in the Realtek Hd Audio manager the sound only comes out of the front and center speakers with a few background noises that come out the rear ones. But since my ears are closer to the rear speakers, I'd rather have the sound come out of them. Let me know of any ideas! Hmm seems like the only option is to set the rear speakers to "Front Speakers" and change it to stereo in the Realtek HD audio. But still that take alot of steps and it doesnt not use the center speaker Thanks

  • Windows 8 can't open any modern UI app

    - by Joyal
    I just upgraded my machine with Windows 7 Pro x64, to Windows 8 Pro x64, with the Windows 8 Upgrade Assistant. Everything went great, but none of the Modern UI Apps open, and they do not show any error messages or warnings, they just close right away I opened them. I tried to open Skydrive, Windows Store, Photo App,Music App, Bing, Videos , Finances and all the available Modern UI apps on my screen My screen resolution is 1080p, so it is not a resolution issue, I'm using a Windows account , but i switched to Local account but didn't solved the issue. I ran Windows Update and updated my nVidia video drivers. I also tried an app called "Metro App Troubleshooter" without luck

  • Windows 7: Open File - Security Warning box appears for every app on the desktop

    - by Michael Ratanapintha
    Whenever I double-click to open an executable on the desktop (.exe, .bat, etc.), or a shortcut on the desktop that points to an executable, the "Security Warning" pops up and asks me "Are you really sure you want to open that? Stuff from the Internet is dangerous!" I don't usually mind this warning and don't want to disable it globally, but now I'm getting it for any executable on the desktop, even ones that I didn't download from the Web and don't have the Mark of the Web alternate data stream. (That is, streams -d * shouldn't and doesn't help.) This started fairly recently, but I can't really point to anything I did that triggered it. It only occurs in one user account on the machine; the other account doesn't have this problem. Running System Restore didn't help. How can I fix the problem and make the pop-up warning appear only when it's supposed to?

  • Good source of reviews of CULV machines?

    - by Jason Sundram
    I'm potentially interested in acquiring a CULV machine. I like the idea of a netbook, but need a little more horsepower. So, of course, I need to obsess over a hundred different reviews first. Can you recommend some good sources of CULV reviews? Anandtech recently ran a roundup, but I'd prefer sites that have ongoing CULV coverage. Thanks!

  • hiera data source in using puppet syntax?

    - by Zoredache
    The documentation for hiera on docs.puppetlabs.com seems to give me the impression that I can use puppet syntax to describe my data. Or posssibly will be able to in the future. See: Coming soon. Is this functionality present in a release version of puppet, and just not documented, or is this still being developed? If this functionality is present, does anyone have examples of how to actually use this? The presence of the puppet_backend.rb file on my system gives which was part of the puppetmaster package makes me thing that this functionality is present, but just not documented. So I am trying to figure out how to actually use this.

  • How to set JS source directory in apache2?

    - by highBandWidth
    I am trying to run a very basic webserver for development/debugging. The static HTML seems to be delivered correctly, but it seems that the JavaScript libraries are not being delivered to the browser. The page HTML says something like <html> <head> <script type='text/javascript' src="/lib/json.js"></script> ... Now, I have set up a link for /lib/ in my httpd.conf as: Scriptalias /lib/ "/SomeFolder/lib/" When I do this, it can't fetch the files because this is what I see in my apache error log: ... [error] [client ::1] client denied by server configuration: /SomeFolder/lib/json.js, referer: http://localhost/SomeSite It seems that apache is not allowing access to the folder, so I add this to httpd.conf: Directory "/SomeFolder/lib/"> Allow from all </Directory> After this, browsing the page still does not run the JS, instead I see the following error in my apache error log: [error] [client ::1] (13)Permission denied: exec of '/SomeFolder/lib/json.js' failed, referer: http://localhost/SomeSite So now, it seems that apache is trying to run the JS files on the server like a cgi script or something. But I have not made that folder a cgi-bin folder. The only lines where SomeFolder is mentioned by name is in these lines in httpd.conf: Scriptalias /lib/ "/SomeFolder/lib/" Directory "/SomeFolder/lib/"> Allow from all </Directory>

  • How do I open a 60M png image on OSX

    - by Topener
    Alright, so I've been looking around on this site on how to open a big PNG image. The question I found was about a 10M png. Xee apparently did the job. So, I downloaded Xee for my 60M file, but it crashes. So does iPhoto, Pixelmator and previewer. In the Pixelmator and Xee case, I actually had to kill the computer, and restart it. It crashed so 'hard' I couldn't get it to respond again. How do I open this file? (and zoom it) Specs: newly acquired macbook pro: 4gb memory, 2.3ghz i7 58M png image approx: 15000x30000 pixels
