  • UNMOUNTABLE BOOT VOLUME win7

    - by user1809318
    i'm having a serious problem with my laptop (Toshiba satellite l40). Two days ago i just turned it off by holding the power button and the next day it didn't start at all. There is a blue screen with an error : UNMOUNTABLE BOOT VOLUME, i searched all over the net for a solution, did almost everything like using the windows 7 install disk and trying to repair with the command prompt (check c: /r, bootfix etc.) it runs the check saying there are no errors and when i restart the blue screen again. Can someone please give me some new solution?

  • Harddrive speed drops a lot!

    - by AZ
    The hard drive is used to do BT with uTorrent. Recently uTorrent began to report there is a "I/O Device error", then I use HD Tune to test it, it turns out the transfer rate is only 16 MB/sec. At the same time, I have a similar hard drive tested, it rates as 120 MB/sec. They are both 7200rpm desktop hard drives. I used chkdsk to fix it but the rate didn't change. Is this a symptom of hard drive failure? Should I backup the content on the disk ASAP or is there any other tool can fix it or diagnosis it?`

  • When NOT to use virtualisation? [closed]

    - by Nils
    When virtualisation was new, we tried to virtualized everything. Then came the cases where the virtual machine was very much slower than a physical one. It boils down to the following ruleset (with us) when not to virtualize: Network-io-intesive applications (i.e. with many interrupts/packets) Disk-io-intensive (if not on SAN storage) RAM-intensive (this is the most precious resource) Now this is true for a combination of XEN using local DRBD storage. The same seems to be true for Hyper-V using DAS. I wonder - is it true for all combinations - and what are your limits on these combinations?

  • Windows 7 boot error 0xc0000225 after falling down

    - by Hulehule20
    My Toshiba netbook fell down and hasn't booted again. When I start Windows 7 it immediately says: Windows failed to start... Status: 0xc0000225 Info: The boot selection failed because a required device is inaccessible. After that, there are a few things to consider: There's a Linux distro Linkat which is also installed in the computer. It starts normally without any problem and it doesn't seem to display any errors when it boots. I restored all computer OSs with clonezilla and some images provided by the manufacturer, and it's done nothing. I have already checked the basic components of the PC (RAM, Hard Disk, WLAN Card) are pluged in and working. My impression is that's all about some broken part inside, though the Linux OS starts normally. Does anyone know a way I can fix this or at least any software for identifying the problem at all?

  • Install Windows 8 (clean) on Hybrid Drive

    - by Ananthakrishnan Ravi
    I have a Sony Vaio T series (UEFI) that consists of a Hybrid Drive (SSD + HDD). I would like to install Windows 8 on the SSD and keep the Program files and other applications on the hard disk. What I could perceive was to keep the SSD as the System Drive. I'm able to install the OS on the SSD, but I run into some issues where I don't see the Microsoft Store App on my system and there are no apps on Windows 8. I tried using this blog post but doesn't seem to fit for Windows 8. Any help in this regard would be great. I would like the Windows 8 alone on the SSD, I don't care about the space wasted on the SSD and install other programs on my HDD. Thanks

  • What is and what is not replicated in a glassfish cluster with a mod_jk load balancer?

    - by Navigateur
    I have a Glassfish (3.1.2) cluster over 2 computers as nodes, with a mod_jk load balancer. Are servlet instance variables replicated perfectly? If not, how do I make sure it is? Are all actions, including method calls and disk writes, replicated perfectly? If not, how do I make sure they are? These may seem like stupid questions, but I'm not seeking "load balancing" as much as I am seeking exact replication to enable future upgrading without any service interruption. How do I achieve this if it is not already the case?

  • New Kingson SSD drive fails after 1 week

    - by user35356
    I upgraded the hard disk in my notebook to a 128GB Kingston SSD V100. Everything worked fine for about a week then out of the blue the notebook would not boot up any more. A black dos-like screen was shown with the options to try and boot normally or attempt to repair windows. Neither option would do anything. When I removed the drive and tested it in an external usb case no other computers are able to access the drive either. Is there anything I can try to fix it myself? The drive is partitioned into three drives and when it's connected through an external usb case to another computer I can see the partitions, just can't access anything on them. Does this mean the drive might be recoverable?

  • Can't use VHD in a particular machine

    - by madth3
    (All the machines referred below have Windows 7 Professional.) I have a virtual machine targetted for Virtual PC. I'm able to use that disk in two different machines (32 bit and 64 bit, respectively). Yet in the machine where I wanted to finally install this virtual machine I get the error that the VHD file is not valid. The faulty machine is 32 bit and has the exact same Virtual PC version as the other machines. The file was correctly copied (SHA1sum says so). Default XP Mode works (therefore Virtual PC is not so wrong) Does anyone have any idea what might be wrong in the target machine?

  • Long term system health monitor

    - by user30336
    As an experienced user, I sometimes notice that things are not going well with my computer. For example, my backup drive recently started cycling up and down, so I guessed it was probably dying, and replaced it. I detected this with my ears. Windows did not seem to notice or care. There ought to be software that monitors overall system health by keeping track of things like this, so that unusual events or increasing error rates will not be shrugged off. Among other things: disk errors that are recovered, corrupt network packets (at above the baseline expected rate) and crashes of trusted programs are early warnings. Is there any software that tries to use this kind of monitoring to warn of impending trouble?

  • vSphere 4 - how can I cancel a file copy in progress?

    - by DrStalker
    VMware vSphere 4 SAN storage with multiple data-stores No vCenter I shut-down a virtual machine and using the data-store browser did a copy/paste to copy the VM to a new datastore with additional space. The file copy performance was very poor, and due to time constraints I decided to cancel the copy task. However the copy task showing in the vsphere client can not be cancelled; the cancel option is disabled. Currently I am not able to start the machine in it's original location as the disk files are locked for the copy. How can I abort the copy? I tried deleting the target directory but this did not abort the copy task.

  • Computer doesn't start at all

    - by Sniffer
    I have a desktop computer that won't start at all, I had it for years, and now suddenly when I press the power button I get no beeps, no fans spinning, no hard disk spinning. And the amazing thing that it sometimes works when I press the power button and every thing works normally. Sometimes it works after an hour, 10 hours or 10 minutes after I press the power button and this problem happens when electricity goes out and comes back. If I managed to turn the computer and no power outage happened. I am able to keep turning it on. But when the electricity goes off and on. And I press the power button it may turn on after an hour, two, 10 or not at all.

  • Hosting ESXI (free edition) [closed]

    - by Peter Adss
    We currently have one physical server running the free version of VMWare ESXi that virtualizes a Win SBS 2003 server and a Citrix server. We need to collocate the server and are investigating our options. Are there places that will host our virtual servers and save us the expense of shipping the physical server out for collocation. In my mind we'd copy the Vms to disk and ship them out. Does the fact that we're using the free version of ESXi create a barrier to this idea? Thanks for the help, I realize this is a stupid question.

  • Insufficient Permissions Problems with MSDeploy and TFS Build 2010

    - by jdanforth
    I ran into these problems on a TFS 2010 RC setup where I wanted to deploy a web site as part of the nightly build: C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v10.0\Web\Microsoft.Web.Publishing.targets (3481): Web deployment task failed.(An error occurred when reading the IIS Configuration File 'MACHINE/REDIRECTION'. The identity performing the operation was 'NT AUTHORITY\NETWORK SERVICE'.)  An error occurred when reading the IIS Configuration File 'MACHINE/REDIRECTION'. The identity performing the operation was 'NT AUTHORITY\NETWORK SERVICE'. Filename: \\?\C:\Windows\system32\inetsrv\config\redirection.config Error: Cannot read configuration file due to insufficient permissions  As you can see I’m running the build service as NETWORK SERVICE which is quite usual. The first thing I did then was to give NETWORK SERVICE read access to the whole directory where redirection.config is sitting; C:\Windows\system32\inetsrv\config. That gave me a new error: C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v10.0\Web\Microsoft.Web.Publishing.targets (3481): Web deployment task failed. (Attempted to perform an unauthorized operation.) The reason for this problem was that NETWORK SERVICE didn’t have write permission to the place where I’ve told MSDeploy to put the web site physically on the disk. Once I’d given the NETWORK SERVICE the right permissions, MSDeploy completed as expected! NOTE! I’ve not had this problem with TFS 2010 RTM, so it might be just a RC issue!

  • PowerShell Script to Deploy Multiple VM on Azure in Parallel #azure #powershell

    - by Marco Russo (SQLBI)
    This blog is usually dedicated to Business Intelligence and SQL Server, but I didn’t found easily on the web simple PowerShell scripts to help me deploying a number of virtual machines on Azure that I use for testing and development. Since I need to deploy, start, stop and remove many virtual machines created from a common image I created (you know, Tabular is not part of the standard images provided by Microsoft…), I wanted to minimize the time required to execute every operation from my Windows Azure PowerShell console (but I suggest you using Windows PowerShell ISE), so I also wanted to fire the commands as soon as possible in parallel, without losing the result in the console. In order to execute multiple commands in parallel, I used the Start-Job cmdlet, and using Get-Job and Receive-Job I wait for job completion and display the messages generated during background command execution. This technique allows me to reduce execution time when I have to deploy, start, stop or remove virtual machines. Please note that a few operations on Azure acquire an exclusive lock and cannot be really executed in parallel, but only one part of their execution time is subject to this lock. Thus, you obtain a better response time also in these scenarios (this is the case of the provisioning of a new VM). Finally, when you remove the VMs you still have the disk containing the virtual machine to remove. This cannot be done just after the VM removal, because you have to wait that the removal operation is completed on Azure. So I wrote a script that you have to run a few minutes after VMs removal and delete disks (and VHD) no longer related to a VM. I just check that the disk were associated to the original image name used to provision the VMs (so I don’t remove other disks deployed by other batches that I might want to preserve). These examples are specific for my scenario, if you need more complex configurations you have to change and adapt the code. But if your need is to create multiple instances of the same VM running in a workgroup, these scripts should be good enough. I prepared the following PowerShell scripts: ProvisionVMs: Provision many VMs in parallel starting from the same image. It creates one service for each VM. RemoveVMs: Remove all the VMs in parallel – it also remove the service created for the VM StartVMs: Starts all the VMs in parallel StopVMs: Stops all the VMs in parallel RemoveOrphanDisks: Remove all the disks no longer used by any VMs. Run this script a few minutes after RemoveVMs script. ProvisionVMs # Name of subscription $SubscriptionName = "Copy the SubscriptionName property you get from Get-AzureSubscription"   # Name of storage account (where VMs will be deployed) $StorageAccount = "Copy the Label property you get from Get-AzureStorageAccount"   function ProvisionVM( [string]$VmName ) {     Start-Job -ArgumentList $VmName {         param($VmName) $Location = "Copy the Location property you get from Get-AzureStorageAccount" $InstanceSize = "A5" # You can use any other instance, such as Large, A6, and so on $AdminUsername = "UserName" # Write the name of the administrator account in the new VM $Password = "Password"      # Write the password of the administrator account in the new VM $Image = "Copy the ImageName property you get from Get-AzureVMImage" # You can list your own images using the following command: # Get-AzureVMImage | Where-Object {$_.PublisherName -eq "User" }         New-AzureVMConfig -Name $VmName -ImageName $Image -InstanceSize $InstanceSize |             Add-AzureProvisioningConfig -Windows -Password $Password -AdminUsername $AdminUsername|             New-AzureVM -Location $Location -ServiceName "$VmName" -Verbose     } }   # Set the proper storage -

  • SQL SERVER – Configure Management Data Collection in Quick Steps – T-SQL Tuesday #005

    - by pinaldave
    This article was written as a response to T-SQL Tuesday #005 – Reporting. The three most important components of any computer and server are the CPU, Memory, and Hard disk specification. This post talks about  how to get more details about these three most important components using the Management Data Collection. Management Data Collection generates the reports for the three said components by default. Configuring Data Collection is a very easy task and can be done very quickly. Please note: There are many different ways to get reports generated for CPU, Memory and IO. You can use DMVs, Extended Events as well Perfmon to trace the data. Keeping the T-SQL Tuesday subject of reporting this post is created to give visual tutorial to quickly configure Data Collection and generate Reports. From Book On-Line: The data collector is a core component of the Data Collection platform for SQL Server 2008 and the tools that are provided by SQL Server. The data collector provides one central point for data collection across your database servers and applications. This collection point can obtain data from a variety of sources and is not limited to performance data, unlike SQL Trace. Let us go over the visual tutorial on how quickly Data Collection can be configured. Expand the management node under the main server node and follow the direction in the pictures. This reports can be exported to PDF as well Excel by writing clicking on reports. Now let us see more additional screenshots of the reports. The reports are very self-explanatory  but can be drilled down to get further details. Click on the image to make it larger. Well, as we can see, it is very easy to configure and utilize this tool. Do you use this tool in your organization?

  • Downloading a file over HTTP the SSIS way

    This post shows you how to download files from a web site whilst really making the most of the SSIS objects that are available. There is no task to do this, so we have to use the Script Task and some simple VB.NET or C# (if you have SQL Server 2008) code. Very often I see suggestions about how to use the .NET class System.Net.WebClient and of course this works, you can code pretty much anything you like in .NET. Here I’d just like to raise the profile of an alternative. This approach uses the HTTP Connection Manager, one of the stock connection managers, so you can use configurations and property expressions in the same way you would for all other connections. Settings like the security details that you would want to make configurable already are, but if you take the .NET route you have to write quite a lot of code to manage those values via package variables. Using the connection manager we get all of that flexibility for free. The screenshot below illustrate some of the options we have. Using the HttpClientConnection class makes for much simpler code as well. I have demonstrated two methods, DownloadFile which just downloads a file to disk, and DownloadData which downloads the file and retains it in memory. In each case we show a message box to note the completion of the download. You can download a sample package below, but first the code: Imports System Imports System.IO Imports System.Text Imports System.Windows.Forms Imports Microsoft.SqlServer.Dts.Runtime Public Class ScriptMain Public Sub Main() ' Get the unmanaged connection object, from the connection manager called "HTTP Connection Manager" Dim nativeObject As Object = Dts.Connections("HTTP Connection Manager").AcquireConnection(Nothing) ' Create a new HTTP client connection Dim connection As New HttpClientConnection(nativeObject) ' Download the file #1 ' Save the file from the connection manager to the local path specified Dim filename As String = "C:\Temp\Sample.txt" connection.DownloadFile(filename, True) ' Confirm file is there If File.Exists(filename) Then MessageBox.Show(String.Format("File {0} has been downloaded.", filename)) End If ' Download the file #2 ' Read the text file straight into memory Dim buffer As Byte() = connection.DownloadData() Dim data As String = Encoding.ASCII.GetString(buffer) ' Display the file contents MessageBox.Show(data) Dts.TaskResult = Dts.Results.Success End Sub End Class Sample Package HTTPDownload.dtsx (74KB)

  • Examples of temporal database designs? [closed]

    - by miku
    I'm researching various database design for historical record keeping - because I would like to implement a prototypical web application that (excessively) tracks changes made by users and let them undo things, see revisions, etc. I'd love use mercurial or git as backend (with files as records) - since they already implement the kind of append-only changes I imagine. I tried git and dulwich (python git API) - and it went ok - but I was concerned about performance; Bi-temporal database design lets you store a row along with time periods, when this record was valid. This sure sound more performant than to operate on files on disk (as in 1.) - but I had little luck finding real-world examples (e.g. from open source projects), that use this kind of design and are approachable enough to learn from them. Revisions à la MediaWiki revisions or an extra table for versions, as in Redmine. The problem here is, that DELETE would take the whole history with it. I looked at NoSQL solutions, too. With a document oriented approach, it would be simple to just store the whole history of an entity within the document itself - which would reduce design plus implementation time in contrast to a RDBMS approach. However, in this case I'm a bit concerned about ACID-properties, which would be important in the application. I'd like ask about experiences about real-world and pragmatic designs for temporal data.

  • The Oracle Linux Advantage

    - by Monica Kumar
    It has been a while since we've summed up the Oracle Linux advantage over other Linux products. Wim Coekaerts' new blog entries prompted me to write this article. Here are some highlights. Best enterprise Linux - Since launching UEK almost 18 months ago, Oracle Linux has leap-frogged the competition in terms of the latest innovations, better performance, reliability, and scalability. Complete enterprise Linux solution: Not only do we offer an enterprise Linux OS but it comes with management and HA tools that are integrated and included for free. In addition, we offer the entire "apps to disk" solution for Linux if a customer wants a single source. Comprehensive testing with enterprise workloads: Within Oracle, 1000s of servers run incredible amount of QA on Oracle Linux amounting to100,000 hours everyday. This helps in making Oracle Linux even better for running enterprise workloads. Free binaries and errata: Oracle Linux is free to download including patches and updates. Highest quality enterprise support: Available 24/7 in 145 countries, Oracle has been offering affordable Linux support since 2006. The support team is a large group of dedicated professionals globally that are trained to support serious mission critical environments; not only do they know their products, they also understand the inter-dependencies with database, apps, storage, etc. Best practices to accelerate database and apps deployment: With pre-installed, pre-configured Oracle VM Templates, we offer virtual machine images of Oracle's enterprise software so you can easily deploy them on Oracle Linux. In addition, Oracle Validated Configurations offer documented tips for configuring Linux systems to run Oracle database. We take the guesswork out and help you get to market faster. More information on all of the above is available on the Oracle Linux Home Page. Wim Coekaerts did a great job of detailing these advantages in two recent blog posts he published last week.

  • Downloading a file over HTTP the SSIS way

    This post shows you how to download files from a web site whilst really making the most of the SSIS objects that are available. There is no task to do this, so we have to use the Script Task and some simple VB.NET or C# (if you have SQL Server 2008) code. Very often I see suggestions about how to use the .NET class System.Net.WebClient and of course this works, you can code pretty much anything you like in .NET. Here I’d just like to raise the profile of an alternative. This approach uses the HTTP Connection Manager, one of the stock connection managers, so you can use configurations and property expressions in the same way you would for all other connections. Settings like the security details that you would want to make configurable already are, but if you take the .NET route you have to write quite a lot of code to manage those values via package variables. Using the connection manager we get all of that flexibility for free. The screenshot below illustrate some of the options we have. Using the HttpClientConnection class makes for much simpler code as well. I have demonstrated two methods, DownloadFile which just downloads a file to disk, and DownloadData which downloads the file and retains it in memory. In each case we show a message box to note the completion of the download. You can download a sample package below, but first the code: Imports System Imports System.IO Imports System.Text Imports System.Windows.Forms Imports Microsoft.SqlServer.Dts.Runtime Public Class ScriptMain Public Sub Main() ' Get the unmanaged connection object, from the connection manager called "HTTP Connection Manager" Dim nativeObject As Object = Dts.Connections("HTTP Connection Manager").AcquireConnection(Nothing) ' Create a new HTTP client connection Dim connection As New HttpClientConnection(nativeObject) ' Download the file #1 ' Save the file from the connection manager to the local path specified Dim filename As String = "C:\Temp\Sample.txt" connection.DownloadFile(filename, True) ' Confirm file is there If File.Exists(filename) Then MessageBox.Show(String.Format("File {0} has been downloaded.", filename)) End If ' Download the file #2 ' Read the text file straight into memory Dim buffer As Byte() = connection.DownloadData() Dim data As String = Encoding.ASCII.GetString(buffer) ' Display the file contents MessageBox.Show(data) Dts.TaskResult = Dts.Results.Success End Sub End Class Sample Package HTTPDownload.dtsx (74KB)
