  • mysql with DRBD on rackspace

    - by Richard Castle
    I am trying to set up a failover secondary MySQL server that is a mirror of my primary MySQL server using DRBD. The problem is that I am on a rackspace cloud server and I need a second partition on both the primary and secondary servers that I will replicate with DRBD. Rackspace does not allow me to create a second partition. I am left with the default single partition. How can I mirror using DRBD?

  • SQL Server 2008 Filestream Impersonation Access Denied error

    - by Adi
    I've been trying to upload a file to the database using SQL SERVER 2008 Filestream and Impersonation technique to save the file in the file system, but i keep getting Access Denied error; even though i've set the permissions for the impersonating user to the Filestream folder(C:\SQLFILESTREAM\Dev_DB). when i debugged the code, i found the server return a unc path(\Server_Name\MSSQLSERVER\v1\Dev_LMDB\dbo\FileData\File_Data\13C39AB1-8B91-4F5A-81A1-940B58504C17), which was not accessible through windows explorer.

  • X:\ is not accessible. Insufficient system resources exist to complete the requested service. Help [

    - by Katherine
    I keeping getting the error message from above on multiple computers that I administer. I wasn't sure if I should be posting this on SuperUser or ServerFault so my apologizes if it should go there... Basically, I have at least 5 computers of varying ages (some fresh out of the box!) throwing the above error. X:\ is one of our network drives that is mapped for users. Most of the time if you shut down the biggest application it will fix the problem, but it's becoming an increasing issue, and I can't keep running around fixing it manually. I have tried to do some research, but most of it just states the obvious without supplying a permanent fix. The machines are all running Win XP SP3, with at least 2gb of ram. Sorry for the delay in getting back to people... a lot of good questions. To respond back to people... It is a windows 2003 server that houses the file share. We have about 175 users, however i cannot state how many are actually accessing the information at a single moment. Considering that this is our largest file share, I would say that probably at least 100+. The files we work with are large, but not that big considering that we do a lot of graphical and video work. ~50mb. That being said, this is error occurs simply when trying to gain access to the server itself, not actual files. When I say close a program, I mean that it can be any program. It doesn't matter which program. It varies from machine to machine, and from day to day. Some days it is Firefox, some days it is Outlook, some days it is Excel. There doesn't seem to be a common bond behind which application could be causing the problem. Thank you for the articles, and the recommendation on paging files. I will have to look into that. None of our computers are set to hibernate, so I am going to rule that out.

  • Is my system good enough for Hotmail Junk Mail Reporting Program? JMRP

    - by Marius
    Hello there! :) Thank you for a great website! I am interested in Hotmails Junk Mail Reporting Program (JMRP). One of the requirements they have are (translated from Norwegian to English), and I wonder if I qualify: Is the IP-address you registered subject to the company name/domain name? Or do you have your own sending rights from the IP address via the hosting company (that you do not share with other senders) We ask that you attach documents supporting this. These are my details: host: smtp.sharedhostingcompany.com username: username for my email account password: my private password. email address: [email protected] Is this what they require? Thank you for your time. Kind regards, Marius

  • 3 TB HDD won't reactivate

    - by isif
    After doing a clean install of Windows 8 my Seagate 3 TB HDD won't reactivate in Disk Management. The two volumes are there but I can't use them for some reason. The drive was previously used with a GPT partition table, I can see the two spanned volumes but can't reactivate either. I backed up all my files from Windows 7 onto that drive and desperately need them back. What can and should I do to get the drive back up and running? When I go to Disk → Properties → Volumes, it claims the drive has a MBR partition style, so converting to GPT somehow without data loss should work. gDisk claims to be able to do that but when I point it to the drive, it claims that it has a GPT partition and a protected MBR partition. Any suggestions on what to do?

  • What are the requirements for an application health monitoring system?

    - by Steven A. Lowe
    What, at a minimum, should an application health-monitoring system do for you (the developer) and/or your boss (the IT Manager) and/or the oeprations (on-call) staff? What else should it do above the minimum requirements? Is monitoring the 'infrastructure' applications (ms-exchange, apache, etc.) sufficient or do individual user applications, web sites, and databases also need to be monitored? if the latter, what do you need to know about them? ADDENDUM: thanks for the input, i was really looking for application-level monitoring not infrastructure monitoring, but it is good to know about both

  • How do I add the Disqus comment system to a Rails application in a similar fashion to Wordpress?

    - by Eric Lubow
    In Wordpress, the Disqus plugin allows you to choose to subscribe to a post via RSS or via email. Is there a pluign similar to the Wordpress plugin for Rails. Norman's Disqus plugin just uses the Disqus site to make it work. I was hoping to have things more stored locally. For an example of what I mean, take a look at this blog entry. I already know that since Rails (this application in particular) is using Authlogic (plus Facebook Connect), that Disqus cannot be too tightly coupled with the Authentication system. Has anyone ever done this or figured out a way to do this?

  • Linux Uninstalling errors

    - by Zack
    I want to uninstall back-track 5 so I deleted the partitions for back-track os. After deleting the partition that used to be for back-track becomes free space as in picture. But I can't delete that partition nor creating a new partition. I used G-Parted from hiren boot cd but it says there is no partition table, you need to create a partition table. But actually I have 5 partitions already. And I thought of restarting might fix it. But after showing post screen my laptop show grub error. I don't know what to do, and I tried to install back-track again to fix the problem but it also says that i do not have any partitions. I can only boot windows by passing through hiren boot cd. But most of the time My computer is not recognizing the external dvd drive, nor the internal so i have to restart again and again, hoping to catch the time computer recognize the dvd drive. Can I change the boot loader to correct the grub error? SOLVED : I have solved the grub error by writing MBR again by using EasyBCD But I still have the format error.

  • BootMgr is missing, usual fixes don't work

    - by parsley72
    I know this question has been asked before but I've tried all the usual fixes and nothing works. Basically the hard drive had two partitions with Vista and Windows 7. I've deleted the Vista partition to make more room and expanded the Windows 7 partition to fill the drive (using GParted). I've tried: Running Startup Repair - it doesn't find any problems. Setting partition to Active - worked. bootsect /nt60 c: - worked. BootRec /FixMbr - worked. BootRec /FixBoot - worked. BootRec /ScanOs - I get the message "Total identified Windows installations: 0" BootRec /RebuildBcd - I get the message "Total identified Windows installations: 0" BcdEdit shows a Windows Boot Manager and a Windows Boot Loader, both on C: partition. What else can I try?

  • Does the Noctua NH-U12-DX 1366 cooling system mount on Asus P6T 1366?

    - by Andrea Ambu
    The Noctua NH-U12-DX 1366 is an aftermarket CPU cooler for LGA1366 Xeon CPUs. On Noctua's site they state: Caution: The NH-U12DX 1366 can only be used on mainboards that have a backplate with screw threads for CPU cooler installation (such as the Intel reference backplate for Xeon 5500). The cooler is thus incompatible with Xeon 3500 and Core i7 mainboards that don’t have such a backplate. How do I know if the Asus P6T has this backplate?

  • Getting out of the Helpdesk. Getting into the system administration.

    - by eric.s
    Today I found out that the job which would have been a promotion for me went to an outside candidate. The position is for a systems admin on our LAN team. I have been working on the helpdesk here for almost two years with another two years experience working it prior. While we are the first tier support we also work in AD, monitor and update certain servers and set up and deploy Windows/Mac images for those we support. What I am looking for here is what can I do to better myself to inside/outside places to move up this ladder? I take what I can from my job - working on projects that I can learn from - but what projects should I be volunteering for? What can I do for myself outside to make me a more viable candidate for a systems admin?

  • List input and output audio devices in Applet

    - by Jhonny Everson
    I am running a signed applet that needs to provide the ability for the user to select the input and output audio devices ( similar to what skype provides). I borrowed the following code from other thread: import javax.sound.sampled.*; public class SoundAudit { public static void main(String[] args) { try { System.out.println("OS: "+System.getProperty("os.name")+" "+ System.getProperty("os.version")+"/"+ System.getProperty("os.arch")+"\nJava: "+ System.getProperty("java.version")+" ("+ System.getProperty("java.vendor")+")\n"); for (Mixer.Info thisMixerInfo : AudioSystem.getMixerInfo()) { System.out.println("Mixer: "+thisMixerInfo.getDescription()+ " ["+thisMixerInfo.getName()+"]"); Mixer thisMixer = AudioSystem.getMixer(thisMixerInfo); for (Line.Info thisLineInfo:thisMixer.getSourceLineInfo()) { if (thisLineInfo.getLineClass().getName().equals( "javax.sound.sampled.Port")) { Line thisLine = thisMixer.getLine(thisLineInfo); thisLine.open(); System.out.println(" Source Port: " +thisLineInfo.toString()); for (Control thisControl : thisLine.getControls()) { System.out.println(AnalyzeControl(thisControl));} thisLine.close();}} for (Line.Info thisLineInfo:thisMixer.getTargetLineInfo()) { if (thisLineInfo.getLineClass().getName().equals( "javax.sound.sampled.Port")) { Line thisLine = thisMixer.getLine(thisLineInfo); thisLine.open(); System.out.println(" Target Port: " +thisLineInfo.toString()); for (Control thisControl : thisLine.getControls()) { System.out.println(AnalyzeControl(thisControl));} thisLine.close();}}} } catch (Exception e) {e.printStackTrace();}} public static String AnalyzeControl(Control thisControl) { String type = thisControl.getType().toString(); if (thisControl instanceof BooleanControl) { return " Control: "+type+" (boolean)"; } if (thisControl instanceof CompoundControl) { System.out.println(" Control: "+type+ " (compound - values below)"); String toReturn = ""; for (Control children: ((CompoundControl)thisControl).getMemberControls()) { toReturn+=" "+AnalyzeControl(children)+"\n";} return toReturn.substring(0, toReturn.length()-1);} if (thisControl instanceof EnumControl) { return " Control:"+type+" (enum: "+thisControl.toString()+")";} if (thisControl instanceof FloatControl) { return " Control: "+type+" (float: from "+ ((FloatControl) thisControl).getMinimum()+" to "+ ((FloatControl) thisControl).getMaximum()+")";} return " Control: unknown type";} } But what I get: Mixer: Software mixer and synthesizer [Java Sound Audio Engine] Mixer: No details available [Microphone (Pink Front)] I was expecting the get the real list of my devices (My preferences panels shows 3 output devices and 1 Microphone). I am running on Mac OS X 10.6.7. Is there other way to get that info from Java?

  • What's the best version control system for handling projects with graphics?

    - by acrosman
    I'm part of a small team (usually just two people), I handle the code, he handles the graphic design. In the past I've used CVS to handle version control of the code files, and while we've included the graphics in the repository, he hasn't derived nearly as much value from it as I have. Are there other packages that provide the better features for supporting graphics? The system would need to have an easy to use GUI interface, as I don't think it's fair to expect a graphic designer to learn command-line tools. Additional aspect: The client software needs to run smoothly on OS X (for the designer), and Windows (for the programmer).

  • How can I redirect the output of Perl's system() to a filehandle?

    - by syker
    With the open command in Perl, you can use a filehandle. However I have trouble getting back the exit code with the open command in Perl. With the system command in Perl, I can get back the exit code of the program I'm running. However I want to just redirect the STDOUT to some filehandle (no stderr). My stdout is going to be a line-by-line output of key-value pairs that I want to insert into a mao in perl. That is why I want to redirect only my stdout from my Java program in perl. Is that possible? Note: If I get errors, the errors get printed to stderr. One possibility is to check if anything gets printed to stderr so that I can quite the Perl script.

  • ASP.NET 2.0 files work in one folder, but NOT in another

    - by Steve
    I am about to leap of a building. I have created an app for a client and all the files are in a folder on their D drive. Now it is time to go production, so I copied all my files and folders to their excisting classic asp folder on the same drive. BUT NOTHING WORKS. The only difference I can see is that DEV does not require HTTPS like the production site. I also made sure all the permissions are the same on both folder. I made sure that the GAC has read rights using the aspnet_regiis tool. I am at the end of my debug knowlegde, could someone please help me out.

  • Is there a way to pass a custom type from C# to Oracle using System.Data.OracleClient?

    - by Frankie Simon
    I was searching online for a solution to passing a string array to a stored procedure in Oracle. The "easy" but messy way was using a comma delimited string. I had found a sample based on which I created my own type of TABLE of VARCHAR2(200). I understood that I could use a constructor created "behind-the-scenes" by Oracle to give a list of values that would, in the PL/SQL, be treated as a TABLE I could iterate through. But when I got to the C# I saw that there is no way for me to create an OracleParameter object that would allow me to use this implicit constructor. All the samples I'm finding online for now are dealing with Oracle Data Adapter, none say anything about System.Data.OracleClient. Is there a way to achieve this?

  • Intel Server Board S3420GP fails to boot with video connected

    - by Riley
    All, Building a new system using an Intel Server Board S3420GP motherboard and an Intel Xeon X3440 processor. Before installing this motherboard into the chassis we want to test that it will actually boot correctly. We have mounted the processor and RAM with no hard drives attached. The boot sequence differs between the next variable: 1) Connecting video results in the system fans ramp up and down, twice, and then the system beeps with the same behavior repeating; the system status light shows "Amber" 2) With no video, the system goes through POST and the diag LEDs show that the system is missing a bootable device Need some assistance identifying why the board would fail to POST with video connected. // Update // Using another Power Supply the system gets passed the fans ramping up and down twice. Video still does not display.

  • Sync sticky notes between Windows 7 and Linux on Dual Boot System?

    - by TheLQ
    I love Windows 7's sticky notes, it really helps. Here's the issue though: I dual boot Windows 7 and Fedora Linux. Whichever OS I'm in is random, depending on what I'm wanting to do at the time. Therefore I can't rely on just keeping the notes in my "primary" OS and referencing it when needed Does anybody know of a way to sync Windows 7's Sticky Notes with Fedora? Various Google searches haven't yielded much as they deal with primarily syncing between common OS's.

  • Is it possible to replace the system open file dialog?

    - by Edwin
    I want to replace the standard system open file dialog with the one I wrote, that means no matter within which programs you are opening a file, my dialog will be shown instead of the standard one, is this possible? It seems that that there is no such API provided to accomplish this, is it possible to use some hooking technique, but this has to be reliable and not to be treated as spyware by anti-virus tools? any other options? If this is not possible, is it possible to add to the spacebar or toolbar in the standard open file dialog a button which invokes my dialog, which allow users select a file and in turn returns the path of the selected file to the "File name" input box of the standard dialog? Any hits, links and code examples will be appreciated.
