  • SQL SERVER – Detect Virtual Log Files (VLF) in LDF

    - by pinaldave
    In one of the recent training engagements, I was asked if it true that there are multiple small log files in the large log file (LDF). I found this question very interesting as the answer is yes. Multiple small Virtual Log Files commonly known as VLFs together make an LDF file. The writing of the VLF is sequential and resulting in the writing of the LDF file is sequential as well. This leads to another talk that one does not need more than one log file in most cases. However, in short, you can use following DBCC command to know how many Virtual Log Files or VLFs are present in your log file. DBCC LOGINFO You can find the result of above query to something as displayed in following image. You can see the column which is marked as 2 which means it is active VLF and the one with 0 which is inactive VLF.

  • Why does Unity3D crash in VirtualBox?

    - by FakeRainBrigand
    I'm running Unity3D in a virtual instance of Windows, using the Virtual Box software on Linux. I have guest additions installed with DirectX support. I've tried using Windows XP SP3 32-bit, and Windows 7 64bit. My host is Ubuntu 12.04 64bit. I installed and registered Unity on both. It loads up fine, and then crashes my entire VirtualBox instance (equivalent of a computer shutting off with no warning).

  • How to unmount a virtual cd/dvd in Ubuntu 11.1o

    - by P J Reil
    I'm new to Ubuntu 11.10 and have absolutely no idea what I'm doing. I don't now how but in downloading and fooling around with a virtual cd/dvd program I seem to have inadvertently installed it. I had to shut down my computer for a while and when I re booted it all my files and my setup was gone. I have a brand new 11.10 setup with all the programs installed that I originally had but no files or bookmarks etc.. I'm not sure, but I think I'm running in a virtual cd/dvd. I don't know how to determine if I am or not and can't boot up in my original setup. Can anyone help me?

  • Why didn't virtual ubuntu halts clearly?

    - by Dims
    I am running Ubuntu 11.10 on Oracle Virtual Box 4.2.4 under Windows 7 x64. To stop guest system I often use halt command which works fine on physical machines. But it looks hanging on virtual ubunty. After halt it starts shutting down, Ubuntu logo appears with dots below flashing. After some cycles it just stops. VM manager does not feel machine is gone, so I need to power off it. P.S. The system stops Ok if I shutdown it via GUI.

  • Compizconfig Grid doesn't work under Ubuntu as virtual machine

    - by SoftTimur
    I have installed Ubuntu as virtual machine within Mac. I have installed VM tools. The approach in this link of Compizconfig Grid, which worked in my previous laptop where Ubuntu was not a virtual machine, does not work anymore. I set some shortcut, but no action is launched... Does anyone know why? The major functionality I need from Grid is tiling windows to left/right side of the screen... Does anyone know any alternative?

  • Visual Studio Load Tests Virtual Users Simulation

    - by Eldar
    Hello, I'm currently working on writing a load testing application that takes advantage of Load Test using Visual Studio 2010. The load test will simulate 20 users on the same machine, and I need some data to be shared in-memory between all simulated users. I was suprised I couldn't find documentation answering the following question: What seperates each virtual user's running context from the other? Does each virtual user runs the tests in its own process? Maybe in its own app domain? Or just on its own thread? I need to know because if each user is running tests in its own process then all the in-memory cache isn't shared and is created for each user instead of one time for all of them, which is bad for me.

  • Connect to a VPN from a Virtual Machine

    - by kaharas
    I am running an Ubuntu ditro inside a VMWare virtual machine with a bridged connection on a windows 7 host. What I am trying to do is to have the virtual machine connect to a VPN, but I'm not having much success. At first, the system was using wicd, but I replaced it with network-manager who's supposed to have OpenVPN support. The problem is, even tho i've purged the wicd installation, there're connections shown in the network manager, and still, I'm able to access the net. I've also added the openvpn data in the network manager tab, but it's shown as never used. PS: when I try to stop and start the NetworkManager service, an error message pops up telling me that there's not such a service, but apt-get tells me i've already installed it...

  • New 64 bit linux system has regular processes (ps, grep etc) taking up way too much VIRT mem

    - by user42980
    We just moved from a 32-bit machine to a 64-bit machine. We have quickly ran out of memory despite the new boxes have twice as much ram as the old boxes. Running a simple ps command will illustrate the problem. New machine: 132 prod-Charlotte1-node1 ~/public_html/rearch/cgi-bin ps aux | grep ps root 293 0.0 0.0 0 0 ? S< May09 0:00 [kpsmoused] xamine 2267 1.0 0.0 63728 928 pts/3 R+ 16:50 0:00 ps aux xamine 2268 0.0 0.0 61172 752 pts/3 S+ 16:50 0:00 grep ps Old machine: 132 prod-116431-node1:/home/xamine ps aux | grep ps xamine 23191 0.0 0.0 2332 768 pts/6 R+ 15:41 0:00 ps aux xamine 23192 0.0 0.0 3668 692 pts/6 S+ 15:41 0:00 grep ps Notice that the ps process is using 63M of VIRT mem vs 2 on the old machine.

  • How do you return a pointer to a base class with a virtual function?

    - by Nick Sweet
    I have a base class called Element, a derived class called Vector, and I'm trying to redefine two virtual functions from Element in Vector. //element.h template <class T> class Element { public: Element(); virtual Element& plus(const Element&); virtual Element& minus(const Element&); }; and in another file //Vector.h #include "Element.h" template <class T> class Vector: public Element<T> { T x, y, z; public: //constructors Vector(); Vector(const T& x, const T& y = 0, const T& z =0); Vector(const Vector& u); ... //operations Element<T>& plus(const Element<T>& v) const; Element<T>& minus(const Element<T>& v) const; ... }; //sum template <class T> Element<T>& Vector<T>::plus(const Element<T>& v) const { Element<T>* ret = new Vector((x + v.x), (y + v.y), (z + v.z)); return *ret; } //difference template <class T> Element<T>& Vector<T>::minus(const Element<T>& v) const { Vector<T>* ret = new Vector((x - v.x), (y - v.y), (z - v.z)); return *ret; } but I always get error: 'const class Element' has no member named 'getx' So, can I define my virtual functions to take Vector& as an argument instead, or is there a way for me to access the data members of Vector through a pointer to Element? I'm still fairly new to inheritance polymorphism, fyi.

  • Is it ok to throw NotImplemented exception in virtual methods?

    - by Axarydax
    I have a base class for some plugin-style stuff, and there are some methods that are absolutely required to be implemented. I currently declare those in the base class as virtual, for example public virtual void Save { throw new NotImplementedException(); } and in the descendand I have a public override void Save() { //do stuff } Is it a good practice to throw a NotImplementedException there? The descendand classes could for example be the modules for handling different file formats. Thanks
