  • What postgresql client version should I build against, if server is 8.x?

    - by Ben Voigt
    I'm planning updates to a system that is currently running with 8.x server on Windows, 8.x client on Windows, and 8.x client on Linux. Obviously that seems like a bad choice of platform in a mixed environment, but the Linux machine has no persistent writable storage (as an anti-rootkit measure). I'm concerned with compatibility between versions right now. Can a linux postgresql 9.0.x client connect to a Windows 8.x server? The server is using some third-party binary extensions, so upgrading it is a more involved task and will be done later. If combining a 9.0.x client and 8.x server is discouraged, would latest 8.x clients be able to continue to connect if I did upgrade the server first? META: What tag is appropriate for backward-compatibility questions?

  • What we have to measure for measuring server performance If we can't measure the server processing time from client side?

    - by AsadYarKhan
    If we can not measure the server processing time from client side then which attributes will be good to measure in client side for measuring server side performance and What attributes are important ? I know we can get the server response time, latency and Throughput etc,but how do we understand/interpret the result of server side from these attrubutes. How can we analyse that whether my code is taking lots of time,whether Web Server, whether it is because of Server Machine(H/W).how would i know that which thing needs to be upgrade or improve.Please tell me any article or any book something that I need to study or explain here If you can so I can interpret the result of server side using these attributes response time, latency and throughput.You can tell other performance attribute if I need to understand the server result.

  • 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.

  • How to update BIOS with efi?

    - by gasko peter
    We have a GA-H61M-DS2 rev 2.0 motherboard. It has an "F4" BIOS. We went to the vendors website: http://hu.gigabyte.com/products/page/mb/ga-h61m-ds2rev_20/download/bios and downloaded "F7", the latest BIOS version. We already tried: 1) "Efiflash.exe H61MDS22.F7" command from windows 7/32bit, it said nothing, the command line just flashed for a second.. 2) boot the win7 in "dos" mode (...) but the same thing happened. Q: How can we upgrade the BIOS? There aren't any ways for it?

  • Resizing a rectangular array

    - by devdept
    Does a smarter way than the following exist to resize a rectangular array? double[,] temp = new double[newSize, originalSecondDimension]; Array.Copy(original, temp, original.Length); I was concerned about duplicating a huge array and the memory necessary to do it. What does the Array.Resize() do internally? Thanks, Alberto

  • How to identify RAID (5 or 6) controllers that allow dynamic resize of the array

    - by David Pfeffer
    I'm building a server with a RAID5 array, based on a hardware controller. I want to be able to later add additional disks and have the array rebalance across all of the disks, enlarging the usable size. I also want to be able to later upgrade to bigger disks (one at a time, of course) and then expand the array to fill the entire drive. These features are available in Linux software raid (md). I've also heard they're available in some hardware controllers. Currently, I own the Adaptec RAID 3805 card and the 3ware 9650se card. I'd prefer to use the Adaptec if possible, but I can't find if either of these cards offer this feature. If they don't, are there other affordable (read as: sub-$600) RAID cards available that can accomplish this?

  • How to version large binary files?

    - by Walter White
    I run Windows XP inside a virtual machine for some tasks. I attempted to use git to version the image for virtual box; however, it is about 6GB after all the service packs. I only have 6GB of ram and git bombs out saying it is out of memory. I would basically like to have snapshots of Windows so that I can simply blow away an image and start anew when I want to. I like to have something I can rollback to in the event that an upgrade doesn't work so I would prefer to use version control or snapshots if the filesystem supports it. Any ideas on what tools I can use to do that?

  • Using SQL Server profiler from 2008 against R2 database

    - by Chris Lively
    On my dev machine I have the management studio tools installed from SQL Server 2008. However, one of the sql server boxes I need to profile against is running R2. Because of this, when I start the profiler and connect to that server all of the templates are gone. If I go to Edit the templates, the R2 server type isn't available as an option. Do I have to upgrade my local toolset to R2 or is there some other way around this? Note, that if I create a template and save it the next time I connect to the server that saved template isn't available.

  • Updating windows xp hard drive controller from ubuntu live disk

    - by Joel
    The problem: When booting, I get a blue screen shortly after the Windows XP logo splash screen. The error code is 7b, and the second hex number is 0xC0000034. Based on this link (item 7) it appears the driver should be updated. Oddly, I made no changes to the drivers recently. I suspect it was something in a windows update or the newest upgrade of my antivirus (eset). But I digress. The BSOD makes me unable to boot into Windows at all, so I can't update the driver from there. I've run various bios-level diagnostics (including full surface scan) and the hd looks good. I'm also able to boot to an old ubuntu disk and read files from the hd. The question: Based on the above, it appears that I need to update the Windows hard drive controller from the ubuntu live disk. How do I do that?

  • Workflow Automation software for SVN

    - by KyleMit
    We're currently using IBM's ClearQuest for task management and ClearCase for change management. They plug and play very well with each other. Users can create tasks in ClearCase as defects and enhancements, and developers can use those tasks to check out and modify code in source control. We're looking to upgrade to a better, more modern Source Control system, like SVN, although we're not married to that as our Source Control system. There are loads of source control systems out there, but I'm having difficulty finding one that also includes the ability to have users enter tasks and track them, especially in a native way to the source control system itself. Are there any products that replace ClearQuest for systems like SVN? Are there any other cheap / open source application pairs that handle both sides of the coin?

  • Windows 8.1 & manual removal of "Sentinel Runtime Drivers"

    - by uos??
    I'm trying to install Windows 8.1 (basic upgrade from Windows 8). It is complaining of Sentinel Runtime Drivers incompatibility. I've looked for it in my Programs & Features list, but it's not there by that name nor SafeNet (as related by google search) nor do I see any obvious candidates for it having been bundled with another listed application. I tried the "Sentinel Runtime Driver Cleanup" program from the SafeNet website. It ran but was ineffective, even after a reboot. Do you recognize this "Sentinel Runtime Drivers"? I ran MalwareBytes too, just in case, but it found nothing.

  • IPhone Development Profile Expired

    - by theiphoneguy
    I really combed this site and others. I read and re-read the related links here and the Apple docs. I'm sorry, but either I am obviously missing something right under my nose, or this Apple profile/certificate stuff is a bit convoluted. Here it is: I have a product in the App Store. I have updated it several times and users like it. My development profile recently expired just when I was improving the app for its next release. I can run the app in the simulator. I can compile and put the distribution build on my iPhone just fine. I went to the Apple portal and renewed the development profile. I downloaded it and installed it in Xcode. I see it in the Organize window. I see it on my iPhone. I CANNOT put the debug build on my iPhone to debug or run with Instruments. The message is that either there is not a valid signed profile or it is untrusted. I subsequently tried to download and install the certificate to my Mac's keychain. Still no success. I checked the code signing section of Project settings and also for the target and the root. All appears to indicate that it is using the expected development profile for debug. Yes, I had deleted the old profile from my iPhone, from the Organizer. I cleaned the Xcode cache and all targets. I have done all of this several times and in varying sequences to try to cover every possibility. I am ready to do anything to be able to debug with Instruments in order to check for leaks or high memory usage. Even though the distribution compile runs fine on my iPhone and plays well with other running processes, I will not release anything without a leaks/memory test. Any ideas will be appreciated. If I missed something obvious, please forgive me - it was not due to just posting a question without searching for similar postings. Thanks!

  • Changing new Tomcat settings from the defaults in STS Eclipse

    - by Ribeye
    I find myself continually having to delete my Tomcat 7 server in STS Eclipse and re-installing. Each time I have to then: a) increase start up time from 45 sec and b) increase Tomcat memory by adding something like this on the "VM Arguments" under the "Arguments" tab: "-XX:MaxPermSize=512m -XX:PermSize=512m -Xms256m -Xmx1024m -XX:-UseGCOverheadLimit" How do you change defaults for a) and b)? Google has plenty of info on changing these one time, but I want to change the defaults for a "new", and on this the search is coming up a blank. Thanks

  • Rack processes taking over CPU under Passenger

    - by pjmorse
    I have a Spree site running the following stack: Nginx 1.0.8 Passenger 3.0.9 Ruby 1.9.2-p290 Rack 1.3.6 Rails 3.1.4 Spree 0.70.5 I recently upgraded from Spree 0.70.3, which also brought a Deface upgrade from 0.7.x to 0.8.0. Since then things have been very unstable. Recently we've seen some CPU-hogging processes which drive load up on the server and grind the whole thing to a stop. They're Rack processes and it looks like Passenger is starting them; they're owned by the site-runner user, an unprivileged user who owns the application code. (Passenger automatically runs the site code as the user who owns it.) If I restart Nginx and kill the runaway processes, it helps for a while, but eventually similar processes return and bog things down again. How can I figure out what's starting these processes, what they're trying to do, and how to stop them?

  • Very slow Windows 7 on Thinkpad T61

    - by bogdanf
    I have a very strange problem with my fresh install of Windows 7 Profesional, 64bits on my Lenovo Thinkpad T61 : The overal performance is very slow, the disk is constantly spinning, even without any program running (after boot, no other programs installed). The boot process is very slow itself (4-5 minutes). I mention that the laptop was fine on XP until the upgrade. Thanks ! Additional info (as requested by the comments) : 2GB RAM Yes, I added all the manufacturer (Lenovo) drivers and updates (using the utility provided by Lenovo) Tried with both 32 and 64 bits editions. The 32 bits one is performing a little better, but not very usable either. The hdd has enough space (20 GB or so) The problem is still present on a fresh install, so no recycle bin emptying or unistall programs (there aren't any except plain 7) would help. I'm not a newbie, so no obvious causes are left unchecked

  • How do I run vino-server without a monitor attached in Ubuntu 10.04

    - by Ole
    I just upgraded to Ubuntu 10.04 yesterday on a headless home server. I use the server for a variety of purposes, and what I don't know how to do via SSH I've alway been able to do through VNC. However, since the upgrade vino-server will no longer run if there isn't a monitor attached. Before it used to start up without a problem. Even by attempting to run the server via SSH gives me a "could not load display" error. Summary: I need to get vino-server running at boot time on a server with Ubuntu 10.04, without a monitor attached.

  • Is Windows Server 2003 on 96 MB possible?

    - by Nifle
    I have an old laptop, a Pentium II with 96 MB. I have had Windows 2000 on it for ages, it was slow but usable. But now I have to upgrade since I can't get my USB-wlan drivers to install (the old PCMCIA network card broke). I would prefer to install Windows XP but I have no spare licence, but I do have a Windows Server 2003 licence. Do you think it's possible (and usable) to squeeze in 2003 on this computer? Edit: Unfortunately 2003 simply refuses to install on the laptop. It hangs with an error message (paraphrased) 2003 has detected a problem with your computer and has halted the installation to prevent damage. And then some error codes This happens very early in the installation while it's copying the installation files just after I accepted the licence. So I give up for now.
