  • How much RAM on a windows VPS (2003, 2008, 2008R2)

    - by Pietro
    Right now I'm running Windows Server 2003 on a VPS with 640mb RAM and it works fine. I would like to upgrade OS to Windows Web Server 2008 or Windows Web Server 2008 R2. I understand that it is difficult to say how much RAM is needed, but can you make a comparison between 2003 and the two new 2008 versions? RAM on VPS is by far the most expensive item, so I wonder if I can get similar performances with 1GB and 2008 or 2008R2 compared to 640MB and 2003. Basically I run IIS, SQL Server and MailEnable.

  • Sharing Windows Folders on a Network... other PCs see but can't access

    - by John
    I'm soooo tired of network setup issues. All I want to do is share a folder and all it's sub-folders so other PCs on my network can view and change this remote location. Why is it that setting a dir to "shared" doesn't actually make it usable in any way? The other PC can see the fodler but is unable to actually open it and look inside. It seems every time I want to do this I go through some semi-random process of right clicking the folder and enabling sharing, then looking in the folder properties to add permissions and other sharing... and then I end up with some folders working but others will randomly block permission on certain files or sub-dirs. I have 5 PCs in my local testing network and I cannot believe it should be this complicated... where is the simple "make this folder work on the network" option?! I have a mixture of XP, Vista & W7 machines, but this seems common to all of them.

  • How do I create DNS entries for EC2 instances created by Auto Scaling?

    - by Evan
    I'm looking into using auto scaling groups for a tier of webservers that would be fronted by an ELB. One of the things I'm having a hard time with is how to give each new instance the proper DNS name. For example, I'd like webservers to have names like frontend-web-XXX.prod.example.com so their names would appear correct in logs and just ease of organization. I have two other tiers I'd ultimately like to make autoscaled and I'd like them to have names like api-web-XXX.prod.example.com as well. I have some experience with cloudformation templates and have spun up individual instances with associated Route53 records but I don't see any indication of how this can be done within an autoscaled group.

  • SSL Certificate for local web server

    - by Firefly
    Is it at all possible to create a self-signed certificate for use on multiple machines on a local network which would stop the browser complaining it is not a trusted site? We have a product which is basically a computer running lighttpd to serve a web interface for configuring the computer (sort of how a router has a web interface). There can also be many of these machines running on the same network with dynamic IP's. What I basically want to do is enable SSL for extra security but I don't want people who are on the local network to be given a browser warning about the certificate not being trusted. Is this at all possible?

  • Setting up Ubuntu Server for hosting Java web applications

    - by Denis Hoss
    I'm trying to set up an Web Server running Ubuntu server to host some Java web applications, with MySQL running on it, an so on .. here is the tutorial I follow: perfect server ubuntu 11.10 The server configuration is: CPU S1155 INTEL Pentium G850 2.9GHz VGA 5GTs 3MB 65W MB Gigabyte GA-H77-D3H Ram 4x4Gb HDD 5x1TB Seagate (4 in RAID5 and 1 for Backup) The problem is that when I am trying to install the Server version of Ubuntu, when the installer asks me whether to activate ATA RAID Devices, and I click yes, he sees only that one, if I click no, he sees all 5 HDD's separate without any RAID, is this normal? I also tried to install the Desktop version on RAID5, but after restart, Ubuntu does't want to boot up, an underscore stands on the top of the screen. I am a newbie in servers and their configuration, in fact I am developer. I need a help from you guys.

  • Displaying same image multiple times at different locations in a web page using JavaScript or CSS

    - by Joe B
    I’m looking to create a web page with 6 coupons on it, two per line in a web space of 1275 X 1650. Each coupon space will consist of a different image. The problem is I will be creating 20 such web pages that will have these coupons on them. Now some of the same images will appear in different locations/positions on the various web pages. Is there a way to update the same image that appear in different locations/positions at the same time? And what language is used to complete this? I’ve tried CSS but it don’t think it’s possible. So should I be using JavaScript.

  • How to disable or tune filesystem cache sharing for OpenVZ?

    - by gertvdijk
    For OpenVZ, an example of container-based virtualization, it seems that host and all guests are sharing the filesystem cache. This sounds paradoxical when talking about virtualization, but this is actually a feature of OpenVZ. It makes sense too. Because only one kernel is running, it's possible to benefit from sharing the same pages of filesystem cache in memory. And while it sounds beneficial, I think a set up here actually suffers in performance from it. Here's why I think why: my machines aren't actually sharing any files on disk so I can't benefit from this feature in OpenVZ. Several OpenVZ machines are running MySQL with MyISAM tables. MyISAM relies on the system's filesystem cache for caching of data files, unlike InnoDB's buffer pool. Also some virtual machines are known to do heavy and large I/O operations on the same filesystem in the host. For example, when running cat *.MYD > /dev/null on some large database in one machine, I saw the filesystem cache lowering in another, monitored by htop. This essentially flushes all the useful filesystem cache in guests (FIFO) and so it flushes the MySQL caches in the guests. Now users are complaining that MySQL is very slow. And it is. Some simple SELECT queries take several seconds on times disk I/O is heavily used by other machines. So, simply put: Is there a way to avoid filesystem cache being wiped out by other virtual machines in container-based virtualization? Some thoughts: Choosing algorithm for flushing filesystem cache in the kernel. (possible? how?) Reserving a certain amount of pages for a single VM. (seems no option for filesystem cache type of pages that reading man vzctl) Will running MySQL on another filesystem get me anywhere? If not, I think my alternatives are: Use KVM for MySQL-MyISAM running VMs. KVM actually assigns memory to the VM and does not allow swapping out caches unless using a balloon driver. Move to InnoDB and tune the buffer pools, dirty pages, etc. This is now considered to be 'nice to have' on the long-term as not everyone responsible for administration of the system understands InnoDB. more suggestions welcome. System software: Proxmox (now 1.9, could be upgraded to 2.x). One big LV assigned for the VMs.

  • How to reduce the need for IISRESET for developing ASP.NET web app in IIS 5.1

    - by John Galt
    I have a web application project on my dev PC running WinXP and hence IIS 5.1. The changes I'm making to this site seem to "take effect" only after I do IISRESET. That is, I make a source change, Rebuild the project and then Start without Debugging (or with debugging). The newly changed code is not "visible" or in effect unless I intervene with an IISRESET. BTW, the "web" tab on the Properties display for the web app project is configured to use the Local IIS web server at project Url: http://localhost/myVirtualDirectory ... but I've noticed the same issue when using the VStudio Dev Server (i.e. I have to stop it by visiting the taskbar tray area in order to see my source changes take effect). Is this something I can change? EDIT UPDATE: Just wanting to clear this up if possible. Two answers diverge below; not sure how to move forward. One states this is to be expected (weakness of IIS 5.1 which in turn is the best WinXP can provide). Another states this is not expected behavior (and I tend to agree since this is the first I've encounted this on the same old WinXP dev platform I've had a long time). I suspect it may be something "deep inside" the Visual Studio 2008 web app which was upgraded to this new IDE from VStudio 2002 (ASP.NET 1.1). I've tried to add comment/questions down each answer path. Thanks.

  • I bought a domain name at GoDaddy and hosting at Dreamhost but the first doesn't work!

    - by janooChen
    I added the Dreamhost's nameservers like 12 hours ago to: I entered to the following panel: Nameservers -> Set Nameservers (I have specific nameservers for my domains) and added Dreamhost's nameservers liek this: Nameserver 1: NS1.DREAMHOST.COM Nameserver 2: NS2.DREAMHOST.COM Nameserver 3: NS3.DREAMHOST.COM So now in the admin panel I see this: Nameservers Nameservers: (Last Update 2/10/2011) NS1.DREAMHOST.COM NS2.DREAMHOST.COM NS3.DREAMHOST.COM But I get this when I run the analysis tools: Attention Required! There are critical issues Accessing Your Web Site Accessing Your Web Site Properly configuring your domain name and hosting account ensures that visitors can access your site. Did I do something wrong or I have to wait 24 to 48 hours? (Dreamhost does display my page because I can access the other domain name I bought together with the hosting) (By the way, if everyone uses the same nameserver, how will go GoDaddy know which is the hosting space that I purchased among all others)? Thanks in advance.

  • Deploying backing bean with composite component in separate jar

    - by Checkoff
    I have some difficulties deploying my web app on JBoss AS 6.1. My current Project is separated into the main web app (controller/managed beans & web frontend using JSF 2 facelets) and one jar with the composite components + backing beans. But when I try to access the page I got an error that the specified component type could not be instantiated. Copying the backing bean into the main web app solves the problem, but this isn't what I want. So is there anything to pay attention to? The backing bean looks like @FacesComponent(value = "elementBase") public class ElementBase extends UINamingContainer { ... } and the composite components interface <composite:interface componentType="elementBase"> ... some attributes </composite:interface> The structure of the jar is the following -- META-INF |-- resources | |-- components | |-- elementBase.xhtml -- com |-- example | |-- ElementBase.class I've also tried to add faces-config.xml within META-INF folder, with the component type, but the component type was still not found.

  • Project. Properties.Settings versus plain old appSettings?

    - by BryanG
    I have an assembly built that uses appSettings in the app.config...pretty straight forward. however, I'm referencing this assembly in a web service, and that web service contains the nAnt build file for this service plus being the entry point for everything. Ideally I'd like to be able to set the assembly's appConfig values from the build file, but is this possible? Or do I have to switch to using the Settings values of the assembly and do something like this in the build: <xmlpoke file="${PublishLocation}\web.config" xpath="//applicationSettings/Namespace.AssemblyClass.Properties.Settings/setting[@name='ExchangeServer']/value" value="${ServerName}" /> You get the idea. Is this possible with just a config? My ideal situation would be to keep the settings more flexible in the appConfig so that when everything is on the server, if frogs rain down, I can update the assembly's config values without rebuilding the solution. Is this even possible (the xpath is wrong, it's just an example of what I'd like to do): <xmlpoke file="${PublishLocation}\web.config" xpath="//appSettings/Namespace/AssemblyClass/add[@key = 'ExchangeServer']/@value" value="${a}" />

  • How do I nicely manage many localhost web site URIs with IIS7

    - by Simeon
    I'm having trouble setting up a clean development environment with all the web sites I'm working on. I'm working on up to 40 different web sites, and at least 5 of them simultaneously. I need them all to be in a site root, for URL management to work with all CMSes. My first attempt was to use increasing port numbers for them, beginning with localhost:1000 and working upwards. Unfortunately, it took a great deal of looking up which port belonged to which web site, and it was very irritating. My second try was mapping the irritating ports to real words using the hosts file. So I ended up with localhost.tele2, localhost.ikea, localhost.volvo etc. Unfortunately, this takes a long time to set up (cleaning and adding to the hosts file, setting web site with highest port number in IIS etc.) and regularly I have to flush the DNS cache in order to get some sites working that I've added/removed from the hosts file. So how do I organize a lot of web sites in IIS7 nicely? Perhaps I've missed a very clever method that you're using.

  • press button to open web page from app

    - by Lee
    I have an app that I want to interact with a web page. Basically I want to press a button and the web page will open in a new view... Sorry I wasn't clear, I am developing on a Mac for an iPhone. Currently I have a "locate me" app that displays your Latitude and Longitude. I want to use those variables to populate 2 of the blanks on a PHP web page/form I have developed. I have added a label and button to my current app, when the button is pressed the URL with the Lat and Long (as passed vars) are displayed in the label. I want those vars to appear on my web page. Hope this is clearer... Solved: I just added these lines of code I found here: NSURL *url = [ [ NSURL alloc ] initWithString: @"http://www.cnn.com" ]; [[UIApplication sharedApplication] openURL:url];

  • Oracle data provider hangs IIS worker process when web site is stopped

    - by Greg
    We're experiencing a nasty issue in Oracle 11g Release 2 where the w3wp process takes over and entire processor core, and debugging shows that the Oracle data provider is throwing ThreadAbortExceptions infinitely. A developer found this issue by doing the following: 1) Browse a web site that uses Oracle data connections locally (http://localhost/OracleWebSite) - we use IIS, not the ASP.NET dev server, for all of our sites. This ensures that the w3wp process is running and that an active Oracle pool of connections exists in the app pool. 2) Stop the web site (or perform a Rebuild All operation in Visual Studio on the web site in question). Our Oracle connection handling in the affected applications (all Oracle web apps) is well-established and robust. This issue does not occur if we disable connection pooling. This issue does not occur in Oracle 11g Release 1.

  • Getting started with html5 web sockets

    - by Stanni
    Hi, I'm very interested in learning about the new feature in html5 called web sockets. I've looked into it and have come out with a few questions. It seems that before I can start implementing this new technology into a web application of mine I need to have a web server which supports it. Does this involve downloading something and installing it on the said server? Is there more than one available? If so where do I find these? I already have experience with JavaScript and html/css of course, Are there any other languages I will need to learn to start using web sockets? Any additional information that you think I might need to know would be appreciated.

  • Getting started with the vCenter Web Client Administration tool

    - by Saariko
    I am trying to access a newly vCenter. The documentation clearly mentions to access the web-admin through: https://localhost:9443/admin-app but since I don't have a windows OS built under the vCenter (I use the vCenter Appliance) There is no localhost to use. If I try with the host IP I get the error: This PDF explains to install IIS component - But it's ESX 4 - and also not talking about appliance. so, a simple question: how can I access the web-app admin tool? also found a similar question on vmware forum. But I can't understand the solution/if any.

  • Ultra-lightweight web browser?

    - by zildjohn01
    Are there any good super-lightweight graphical web browsers out there? I'd like to be able to browse the web on an old PC, but the mainstream crop of browsers is just too heavy, and I don't want to resort to something like Lynx. There must be something decent out there that'll fit in 16 or 32MB of RAM comfortably. 100% standards compliance isn't necessary, but I'd like something that supports the most widely used parts of CSS and JavaScript. The goal is to get 98% of sites usable in a nice, graphical format.
