  • virtual appliance resources

    - by user11457
    I'm fairly new to appliances but have become a big fan of virtualization. Are there any other resources where I can find and download virtual appliances outside of vmware's website? Or do I just need to scour the web looking them? I'm sure there is a central site that lists all the virtual appliances available, if there isn't I'm going to write one.

  • Accessing local resources over wifi with a BES-connected Blackberry

    - by bshacklett
    I'm trying to get to a local web site on my LAN at 192.168.1.10 with my Blackberry, but I'm getting a message saying the server did not respond. I know that some, if not all, internet traffic on a BES-connected blackberry goes through the BES. This is clear because I can access internal resources on my employers network via the mobile network. Is there any way for me to specify that the device should attempt to route directly over wifi before it tries to connect via the BES server at work?

  • HDD Producing high pithched beep noise

    - by POTHEN
    Recently I had an upgrade on one of my PC I added a 512Mb Nvidia Graphic card and 500GB seagate 7200Rpm HDD, Now the new HDD is producing a high pitched squeek/beep i cant really tell and on reboot my XP sector 63 gets corrupted, so I get reboot error. I gave the HDD for replacement but the replaced one too makes the noice, yet the HDD does not produce sound on my gaming rig.

  • Wireless traffic stops when downloading large files at high speed: packets lost (Linksys WRT120N router)

    - by Torious
    The problem Note: First I'd like to understand WHY this is happening. Ofcourse, a solution would be nice too. :) When downloading a large file over HTTP at high-speeds, my wireless traffic basically stops: I can't open webpages and the download itself pauses. It pauses pretty much immediately after starting it; sometimes at 800 KB, sometimes at a few MB. After some time, the download (and other traffic) resumes, but the problem keeps reoccurring during the same download. The problem does not occur when using a wired connection through the same router (Linskys WRT120N). Also note that the connection is not dropped when this happens. It's just that the traffic stops and I can't browse to web pages, etc. (SYN packets are sent but nothing is received, etc.) Inspection with Wireshark shows that the following happens: Server sends data packets which are acknowledged by client Server sends a packet, but SEQ indicates some packets were lost (6 packets in one occurrence). Server sends a few more packets and client acknowledges these using "selective acknowledgement" Server stops sending data for a while (since the lost packets were not acknowledged or the router stops forwarding them?) Eventually, server does a "retransmission" and traffic resumes as normal. This all seems normal behavior to me when packet loss occurs. It's the consistent packet loss throughout a large, high-speed download that puzzles me. What might cause this? My own idea is the following: My internet is pretty fast (100 mbps), so when starting a large-file download, the router buffers the incoming data (since wireless introduces some slight delay / lower speed, in part due to other networks), but the buffer overflows and the router drops packets to regulate traffic (and because it has no choice). But how could that happen? Doesn't the TCP window size limit the amount of data that can go unacknowledged? So how can the router's buffer overflow if there can only be like 64 KB waiting to be acknowledged? Note: I've disabled TCP window scaling and dynamic window size through netsh options, in an attempt to fix this, but it doesn't seem to matter. Also, Wireshark shows a pattern of the server sending 2 packets (of 1514 bytes) and the client sending an ACK, so does that rule out a possible buffer overflow? And a few more subsequent packets are received... I'm at a loss here. Thanks for any insights. Things that are (probably) NOT the cause / I have experimented with The browser Various TCP options in Windows 7 (netsh etc.) Router settings such as MTU, beacon interval, UPnP, ...

  • PHP Websites: Very high IOPS

    - by Khuram
    We are hosting a set of websites on VM Cloud. These sites were previously on a couple of dedicated servers but to enhance performance, we transferred them onto a Cloud environment. The Cloud has SSD storage but they are now saying that we have very high IOPS and are goign to degrade us if we do not do anything soon. We have good PHP Websites but they are run without any Caching. how do I start to debug this? Sincerely, Khuram

  • Diagnosing a Memcache server with a high cache miss rate

    - by Hobozilla
    Hi Guys, What tools are available to debug a memcache server with a high miss rate (62%)? Ideally I would like to know the keys for the top cache misses, but I would just settle for seeing the keys of live get requests and working it out from there. I have tried a few web based things (phpMemcache) but it doesn't have the information I need. I also tried statsproxy-1.0 which appeared to do what I need but would not play ball. Many thanks

  • Diagnostic high load sys cpu - low io

    - by incous
    A Linux server running Ubuntu 12.04 LTS with LAMP has a strange behaviour since last week: - cpu %sys higher than before, nearly equal %usr (before that, %sys just little compare with %usr) - IO reduce by half or 1/3 compare with the week before I try to diagnostic the process/cpu by some command (top/vmstat/mpstat/sar), and see that maybe it's a bit high on interrupt timer/resched. I don't know what that means, now open to any suggestion.

  • Set process priority to High: Dangerous?

    - by eek142
    I have read that setting something to realtime is a big no-no, so I am not going to do that. But I do have an application that I need to make sure always has the highest priority on my system as it is critical for the rest of the applications I am running. Is there any danger in setting the priority to high, which is one level below realtime? Also, how would I be able to do this by changing the shortcut target? What is the command?

  • High CPU usage - symptoms moving from server to server after bouncing

    - by grt3kl
    First off, I apologize if I didn't include enough information to properly troubleshoot this issue. This sort of thing isn't my specialty, so it is a learning process. If there's something I need to provide, please let me know and I'll be happy to do what I can. The images associated with my question are at the bottom of this post. We are dealing with a clustered environment of four WebLogic 9.2 Java application servers. The cluster utilizes a round-robin load algorithm. Other details include: Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_12-b04) BEA JRockit(R) (build R27.4.0-90_CR352234-91983-1.5.0_12-20071115-1605-linux-x86_64, compiled mode) Basically, I started looking at the servers' performance because our customers are seeing lots of lag at various times of the day. Our servers should easily handle the loads they are given, so it's not clear what's going on. Using HP Performance Manager, I generated some graphs that indicate that the CPU usage is completely out of whack. It seems that, at any given point, one or more of the servers has a CPU utilization of over 50%. I know this isn't particularly high, but I would say it is a red flag based on the CPU utilization of the other servers in the WebLogic cluster. Interesting things to note: The high CPU utilization was occurring only on server02 for several weeks. The server crashed (extremely rare; we are not sure if it's related to this) and upon starting it back up, the CPU utilization was normal on all 4 servers. We restarted all 4 managed servers and the application server (on server01) yesterday, on 2/28. As you can see, server03 and server04 picked up the behavior that was seen on server02 before. The CPU utilization is a Java process owned by the application user (appown). The number of transactions is consistent across all servers. It doesn't seem like any one server is actually handling more than another. If anyone has any ideas or can at least point me in the right direction, that would be great. Again, please let me know if there is any additional information I should post. Thanks!

  • FC SAN network high-error rate simulation

    - by Wieslaw Herr
    Is there a way to simulate a malfunctioning device or a faulty cable in a FC SAN network? edit: I know shutting down a port on a switch is an option, I'd like to simulate high error rates though. In an ethernet network it would be a simple case of adding a transparent bridge that discards a given percent of the packets, but I have absolutely no idea how to tackle that in an Fibre Channel environment...

  • Choosing parts for a high-spec custom PC - feedback required [closed]

    - by James
    I'm looking to build a high-spec PC costing under ~£800 (bearing in mind I can get the CPU half price). This is my first time doing this so I have plenty of questions! I have been doing lots of research and this is what I have come up with: http://pcpartpicker.com/uk/p/j4lE Usage: I will be using it for Adobe CS6, rendering in 3DS Max, particle simulations in Realflow and for playing games like GTA IV (and V when it comes out), Crysis 1/2, Saints Row The Third, Deus Ex HR, etc. Questions: Can you see any obvious problem areas with the current setup? Will it be sufficient for the above usage? I won't be doing any overclocking initially. Is it worth buying the H60 liquid cooler, or will the fan that comes with the CPU be sufficient? Is water cooling generally quieter? Is the chosen motherboard good for the current components? And is it future-proof? I read that the HDD is often the bottleneck when it comes to gaming. I presume this is true to other high-end applications? If so, is my selection good? I keep changing my mind about the GPU; first the 560, now the 660. Can anyone shed some light on how to choose? I read mixed opinions about matching the GPU to the CPU. Will the 560 or the 660 be sufficient for my required usage? Atm I'm basing my choice on the PassMark benchmarks and how much they cost. The specs on the GeForce website state that the 560 and the 660 both require 450W. Is this a good figure to base the wattage of my PSU on? If so, how do you decide? Do I really need 750W? The latest GTX 690 requires 650W. Is it a good idea to buy a 750W PSU now to future-proof myself?

  • Biztalk Server 2009 - Failover Clustering and Network Load Balancing (NLB)

    - by FullOfQuestions
    Hi, We are planning a Biztalk 2009 set up in which we have 2 Biztalk Application Servers and 2 DB Servers (DB servers being in an Active/Passive Cluster). All servers are running Windows Server 2008 R2. As part of our application, we will have incoming traffic via the MSMQ, FILE and SOAP adapters. We also have a requirement for High-availability and Load-balancing. Let's say I create two different Biztalk Hosts and assign the FILE receive handler to the first one and the MSMQ receive handler to the second one. I now create two host instances for each of the two hosts (i.e. one for each of my two physical servers). After reviewing the Biztalk Documentation, this is what I know so far: For FILE (Receive), high-availablity and load-balancing will be achieved by Biztalk automatically because I set up a host instance on each of the two servers in the group. MSMQ (Receive) requires Biztalk Host Clustering to ensure high-availability (Host Clustering however requires Windows Failover Clustering to be set up as well). No loading-balancing option is clear here. SOAP (Receive) requires NLB to achieve Load-balancing and High-availability (if one server goes down, NLB will direct traffic to the other). This is where I'm completely puzzled and I desperately need your help: Is it possible to have a Windows Failover Cluster and NLB set up at the same time on the two application servers? If yes, then please tell me how. If no, then please explain to me how anyone is acheiving high-availability and load-balancing for MSMQ and SOAP when their underlying prerequisites are mutually exclusive! Your help is greatly appreciated, M

  • C#/.Net: What are the best practices for setting ResXResourceReader's basepath?

    I am working on a Windows Forms application in C#/.Net. I want to use a resource file that contains translations of my strings. My my project in visual studio I have the following hierarchy: Project CS files ... Resources\ resource.en-US.resx I am trying to read in the resource file as follows: m_ResourceReader = new ResXResourceReader("resources/resource.en-US.resx"); When I run this project, Visual Studio seems to look for the resources folder in the bin/Debug output folder of my project. My questions are: What is the right way to reference a resource file? I would like my installer to place this resource file under my application's folder under Program Files\MyApp\resources\resource.en-US.resx. What would be the way to make ResXResourceReader read it from that location. Thanks for your help. -Raj

  • Performance Tuning a High-Load Apache Server

    - by futureal
    I am looking to understand some server performance problems I am seeing with a (for us) heavily loaded web server. The environment is as follows: Debian Lenny (all stable packages + patched to security updates) Apache 2.2.9 PHP 5.2.6 Amazon EC2 large instance The behavior we're seeing is that the web typically feels responsive, but with a slight delay to begin handling a request -- sometimes a fraction of a second, sometimes 2-3 seconds in our peak usage times. The actual load on the server is being reported as very high -- often 10.xx or 20.xx as reported by top. Further, running other things on the server during these times (even vi) is very slow, so the load is definitely up there. Oddly enough Apache remains very responsive, other than that initial delay. We have Apache configured as follows, using prefork: StartServers 5 MinSpareServers 5 MaxSpareServers 10 MaxClients 150 MaxRequestsPerChild 0 And KeepAlive as: KeepAlive On MaxKeepAliveRequests 100 KeepAliveTimeout 5 Looking at the server-status page, even at these times of heavy load we are rarely hitting the client cap, usually serving between 80-100 requests and many of those in the keepalive state. That tells me to rule out the initial request slowness as "waiting for a handler" but I may be wrong. Amazon's CloudWatch monitoring tells me that even when our OS is reporting a load of 15, our instance CPU utilization is between 75-80%.

From my limited experience I draw the following conclusions/questions: We may be allowing far too many KeepAlive requests I do see some time spent waiting for IO in the vmstat although not consistently and not a lot (I think?) so I am not sure this is a big concern or not, I am less experienced with vmstat Also in vmstat, I see in some iterations a number of processes waiting to be served, which is what I am attributing the initial page load delay on our web server to, possibly erroneously We serve a mixture of static content (75% or higher) and script content, and the script content is often fairly processor intensive, so finding the right balance between the two is important; long term we want to move statics elsewhere to optimize both servers but our software is not ready for that today I am happy to provide additional information if anybody has any ideas, the other note is that this is a high-availability production installation so I am wary of making tweak after tweak, and is why I haven't played with things like the KeepAlive value myself yet.

  • Getting a Spring resource

    - by Javi
    Hello, I'm trying to read a css file with the Resources provided by Spring. My application looks like this: src src/com herer my classes inside packages WebContent WebContent/resources/style/myCSS.css -- the css I want to read WebContent/WEB-INF -- here is my application-context.xml I can get the css and read it by doing something like this: UrlResource file = new UrlResource("http://localhost:8080/myApp/resources/style/myCSS.css"); but it depends on the server and aplication names. I've tried to do it by other implementations of Resource Interface, but the file is not found cause I can't find out how to wite the path. I've tried with this: FileSystemResource file = new FileSystemResource("/WebContent/resources/style/myCSS.css"); I also tried with wildcards, but it doesn't find the file either. ApplicationContext ctx = new FileSystemXmlApplicationContext("classpath*:/WEB-INF/application-context-core.xml"); Resource file = ctx.getResource("file:**/myCSS.css"); How should I write the path to get the css. Thanks.

  • Resources on wordpress theme-development

    - by Espenhh
    What are the best resources for Wordpress theme-development? I am currently in the phase of starting my own blog, and don't want to use one of the many free themes. I already have a theme for my website, so I want to read about best-practices. Any advice on how to get started would be very welcome :) I have now created my theme (wohoo!), and thought I should summarize the best resources I found. Lets see.. Resources: ThemeTation's three-part guide to create a wordpress-theme from scratch Nettuts.com's guide: How to Create a Wordpress Theme from Scratch (And Part 2) Didn't actually use this, it's a quite new article, but anyway - it's great. It will get a follow-up in the next few days too.. Wordpress.org's own guide on templates Definatly a must-read for everyone new to wordpress-designing.. "The loop" Essential knowledge, also a must-read Directory of all the template tags Used by wordpress to actually output blog-content.. Inspiration: Smashing Magazine's lists: first, one more, yet another one Wordpress.org's theme-directory
