  • Oracle Virtualization Friday Spotlight - November 8, 2013

    - by Monica Kumar
    Hands-on Private Cloud Simulator In One Hour Submitted by: Doan Nguyen, Senior Principal Product Marketing Director My aeronautics instructor used to say, "you can’t appreciate flying until you take flight." To clarify, this is not about gearing up in a flying squirrel suit and hopping off a cliff (topic for another blog!) but rather about flying an airplane. The idea is to get hands-on with the controls at the cockpit and experience flight before you actually fly a real plane. After the initial 40 hours of flight time, the concept sank in and it really made sense.This concept is what inspired our technical experts to put together the hands-on lab for a private cloud deployment and management self-service model. Yes, we are comparing the lab to a flight simulator! Let’s look at the parallels: To get trained to fly, starting in the simulator gets you off the ground quicker. There is no need to have a real plane to begin with. In a hands-on lab, there is no need for a real server, with networking and real storage installed. All you need is your laptop The simulator is pre-configured, pre-flight check done. Similarly, in a hands-on lab, Oracle VM and Oracle Enterprise Manager are pre-configured and assembled using Oracle VM VirtualBox as the container. Software installations are not needed. After time spent training at the controls, you can really appreciate the practical experience of flying. Along the same lines, the hands-on lab is a guided learning path, without the encumbrances of hardware, software installation, so you can learn about cloud deployment and management.  However, unlike the simulator training, your time investment with the lab is only about an hour and not 40 hours! This hands-on lab takes you through private cloud deployment and management using Oracle VM and  Oracle Enterprise Manager Cloud Control 12c in an Infrastructure as a service IaaS model. You will first configure the IaaS cloud as the cloud administrator and then deploy guest virtual machines (VMs) as a self-service user. Then you are ready to take flight into the cloud! Why not step into the cockpit now!

  • Windows Repairs Itself After Ubuntu Boot

    - by pjtatlow
    I have a custom built computer in my home which was running Windows 7 primarily. After I installed Ubuntu 12.04 and upgraded to 12.10, Windows 7 has to perform startup repair after every Ubuntu boot up. For example, I am using Ubuntu for my everyday work, but when I switch to Windows to play one of my steam games, windows fails to boot, and it switches to the recovery partition to "repair windows" then boots windows. The whole process takes about 20 minutes, which is quite annoying. Anyone know why this is happening or what I can do? Thanks in advance!

  • How to deal with "software end-of-life" situations?

    - by rwong
    When a vendor declares that they no longer intend to provide any support or services to a piece of software (and stated the intent to exit the business - offering no upgrade paths), and stated that customers must pay a nominal fee in order to have the existing data exported, what kind of recourse do programmers/customers have? Things I can think of: Need to purchase spare hardware and set up a spare environment on which the software can continue to operate. Various data export methods which do not require vendor involvement. (For example, screen scraping, printing to image followed by re-scanning, etc) Parallel systems where staff will duplicate the old data into a new system manually or semi-automatically Legal means, in case the vendor is in financial trouble Any other ideas? Assuming that there is no "circumvention" involved (no DRM, no DMCA), is data recovery or reverse engineering legal/acceptable?

  • Google Webmaster Tools Index dropped to Zero [closed]

    - by Brian Anderson
    Earlier this year I rebuilt my website using ZenCart. Immediately I saw a drop in index status from 59 to 0. I then signed up for Google Webmaster Tools and noticed the Index status took a dramatic drop and has never recovered. I have worked to add content and I know I am not done, but have not seen any recovery of this index since. What confuses me is when I look at the sitemap status under Optimization it shows me there are 1239 submitted and 1127 pages indexed. Most of my pages have fallen off page one for relevant search terms and some are as far back as page 7 or 8 where they used to be on the first page. I have made some changes in the past week to robots.txt and sitemap.xml, but have not seen any improvements. Can anyone tell me what might be going on here? My website is andersonpens.net. Thanks!

  • [EF + Oracle] Intro

    - by JTorrecilla
    Prologue I have a busy personal and working time, and at this moment that I start to get more free time, I decided to start a Serie about Entity Framework with Oracle. A few time ago, I got my first experience with EF and Oracle with Oracle 10 g express and Oracle 10 g with the same results, Doesn’t work. Now I download Oracle 11 g to Test again. Tools To start using EF with Oracle we need the following: 1. Visual Studio 2010. No Express Edition 2. Oracle 11g 3 Oracle Driver for EF (ODAC) Intro People, who are starting with EF developments, I recommend to take a look into Unai Zorrilla’s Blog, the post were written in Spanish but they are great! To this Serie, we are going to define the DB from the Oracle administrator. For that we need to follow the next steps: 1. Create a User with a PassWord. In my example the user will be Jtorrecilla 2. Create a TableSpace 3. Define some example tables   (Image1) When we have created the DB, we are going to start a new project in VS 2010. I will start a C# Project. To start with EF, we need to add a new objet to our Project “ADO .NET Entity Data Model". (Image2) The next step will be to indicate that our model will be based on an existing DB, and indicate the connection string (Images 3 and 4): (Imagen3) (Imagen4) Once we selected the connection string, we will need to indicate that in the connection will be saved “Sensitive” data (Image 5), and in the next step we are going to select the DB objets to use in the project(Image 6).   (Image 5) (Image 6) A the end of the selection, we will press Finish button, and it will generate a EDMX file to add to our solution, and in the IDE will appear the DB Schema with the selected Tables and Relations. (Imagen7) One Entity is composed by a set of properties (each matches with a column from the Table in the DB) and Navigation Properties that represents any relation with other Entities.   Finally With this chapter we have installed the environment, defined a DB and configured the solution to start using EF with Oracle. In the next chapter we are going to see What is a Entity and how it works. I hope you enjoy this Serie!

  • Upgrade 11.10 to 12.04 on Eee PC failed. GLIBC_2.14 not found

    - by user69170
    I was upgrading my Eee PC from 11.10 to 12.04 as prompted and the upgrade locked up (the lappy was plugged into power - so that wasn't the problem). The system won't boot now and I'm getting an error that "GLIBC_2.14 not found". I am unable to boot into any recovery mode or prior version. The lappy was a dual boot, but when I installed Ubuntu the first time, I opted out of that option (whoops). Now I can't load, it goes into a forever 'ubuntu' loading screen. I have a fresh install on a memory stick, but when I set the lappy to boot from it - it doesn't work. Help. I have no idea what to do next... ??

  • The old "do as I say, not as I do" problem

    - by AaronBertrand
    Microsoft is often considered a leader, an innovator, a trend-setter. The same could be said for Apple, Google, and a host of other tech companies. And each of those has its set of critics as well, who think that the company is the opposite - or worse. Some people think it is a good idea to model their own code, architecture or applications after things that these companies have done, but this is not always the best approach. Humans work at these companies too, and everyone is prone to mistakes,...(read more)

  • Why does update-grub not find ubuntu 11.10?

    - by Klaynos
    I've recently installed ubuntu onto my laptop. With the intention of dual booting with windows 7. On installation Grub wasn't loading, the computer continued to boot straight into windows. I loaded a live cd, mounted the installed ubuntu partion (sda6) as /mnt/ and windows boot partition as /mnt/boot Following the second option here: http://ubuntuguide.net/how-to-restore-grub-2-after-reinstalling-windows-xpvistawin7 Through its entirety, so creating a new grub.cfg file. chroot /mnt update-grub Did not find ubuntu, just windows 7 and the windows recovery partition. Thinking this might be a weird quirk that as I was in ubuntu (all be it a live cd) it might not list ubuntu I restarted. Grub loaded but ubuntu was nowhere to be seen. How can I add ubuntu with Grub2? I could have fixed this myself in old grub but I'm pretty much in the dark here. Thanks

  • Grub errors during UEFI dual boot for Windows 8 (can't find command 'drivemap')

    - by luca-mastro
    I have got a newly bought ASUS N56V with Windows 8 preinstalled. I needed to install Ubuntu so i partitioned the disk and after having disabled the Secure Boot option from Windows 8 i successfully installed Ubuntu 12.10 from a Live USB. The problem is that if i try to access both to Windows 8 (loader) and Windows Recovery System (loader) from the GRUB menu, these two errors show: can't find command 'drivemap' and invalid EFI file path and it goes back to the grub menu. In conclusion I do not have access to my Windows 8 partition but can only use Ubuntu. How can I solve the problem? I am pretty new to the matter. Thank you!

  • Would Ubuntu support this Avell G1711?

    - by Bernardo
    I just bought a gaming notebook (model G1711) from a local brand in Brazil named Avell. Its configuration is quite advanced and this is the reason for my purchase. However, all of their official support relies on Windows 7 or 8, actually. So would Ubuntu work on this machine? It is an i5 Haswell, Chipset Intel HM87, Nvidia Geforce GTX 765M, sound with THX TruStudio Pro, Blu-ray writer, US layout keybord 101/102, USB 2 and 3.0, eSata port, 9 in one memory card reader.

  • Garbled display after Ubuntu upgrade to 2.6.32-2* kernel

    - by Matthias
    I was running Ubuntu 9 (Karmic Koala) with no problems. I recently upgraded to Ubuntu 10 (Lucid Lynx) and cannot use it normally. After I log in, the screen scrambles (a purple/green mess)--impossible to see anything, although I can get out by marking the spot on the screen to click for a restart, so Linux is working behind the scenes. If I start in recovery mode with basic graphics, I have no problems at all (other than limited functionality). If I start the old 2.6.31-22 kernel, I see a bunch of "unmountable" errors in the startup script, but I can use Linux normally with no apparent problems. I'm running an IBM ThinkPad A30 with ATI Mobility graphics. Just to reiterate, the screen looks normal until I log in, at which point it goes bonkers. What do I need to change in order to fix this?

  • Wireless card unseen by lspci

    - by al-Amjad Tawfiq Isstaif
    I installed both Ubuntu 8.04 and 10.04. I tried to install the wireless card. although I succeeded in installing the driver using ndiswrapper, it tells me that the hardware is not present. When I use lspci, it doesn't list it. I have this laptop model and I think it should have the same entry about the wireless card here: http://ubuntuforums.org/showthread.php?t=1810193 Could the problem be other than hardware malfunction?

  • Fail to load Ubuntu11.10 onto ASUS PC 1015PX

    - by strugglingbadly
    My new ASUS 1015PX has the usual windows on the SDA1 partition - 100Gb, followed by SDA2 - 15Gb - with the recovery for windows, SDA3 with 183Gb for drive 'D' for windows. ASUS uses SDA4 - 19Mb for it's own use. 11.10 on an USB will load Ubuntu on a try basis and it seems OK, but every time I attempt an install, Ubuntu quickly shuts down and the restart process begins. Repeat endlessly. I've tried 10.4 netbook but that will not boot at all with the machine reporting - unknown keyword in config file gfxboot vesamenu.c32: not a COM32R image. I've gone through the above about 6 times each with the same results. I have also tried the above with the partitioning unchanged, and using gparted, with SDA3 formatted to ext4, windows 'D' reduced to 8Gb providing a 175Gb unallocated space - all to no avail. Please help

  • Should I choose 10.04 LTS or 10.10?

    - by torbengb
    I'm new to Ubuntu (and Linux) but I want to give it a go. I've spent a few evenings trying to get 10.10 to run but I think my nVidia 8400 GS is causing trouble; only recovery mode with failsafeX gets me to the desktop (low-res but seems to be fully functional otherwise). Given that the xx.04 vesions are long-term support, I'm wondering whether it would be smarter for me to use that. I don't need to be on the cutting edge - I prefer to have a system that just works, long-term. Later I hope to move my media center and wife's netbook over too. Question: Why should I (not?) choose the 10.04 LTS version over the newest 10.10 version?

  • Is that possible to natively boot Ubuntu Touch on a PC, especially on a Surface Pro?

    - by Jules P.
    I know the question has already been asked, but the link for the instructions in the answer is outdated and the proof of concept video doesn't match with what I'm looking for. I've got a Surface Pro (1st model), I've already ran Ubuntu and Android on it several times with UnetBootin, so the question is : Is there a way to natively run Ubuntu Touch (By natively I mean by directly booting it, even on a USB key, but no emulation, no virtualization) on such a device ?

  • Defining a service layer: the text-based adventure

    - by Stacy Vicknair
    Applications these days have more options than ever for a user interface, and it’s only going to grow. A successful product might require native applications for mobile devices, a regular web implementation, or even a gaming console. These systems often will be centralized and data driven. The solution is one that’s fairly solitary, a service layer! Simply put, take what’s shared and put it behind a physical or abstract layer that defines the boundary between the specific user interface and the shared content.   I know, I know, none of this is complicated. But some times it can be difficult to discern what belongs on which side of the line. For instance, say we’re creating a service that will provide content for both an ASP.NET MVC application and a WP7 application. Although the content served to each application is the same, there are different paradigms and patterns for displaying that data in the different environments. In ASP.NET MVC, you may create a model specific to a page that combines necessary information. In the WP7 application you might require different sets of data that you will connect via MVVM with the view. The general rule of thumb is that any shared content, business rules, or data should exist separately. Any element that is specific to the current UI implementation should be included in a separate library or with the UI implementation itself. The WP7 application doesn’t need my MVC specific model classes. My MVC application doesn’t require those INotifyPropertyChanged viewmodels that the WP7 application depends on. In both cases, there should be additional processing done above the service layer to massage the data to the application’s specific needs.   Service-ocalypse: the text based adventure What helps me the most about deciding whether or not something belongs coupled to the UI implementation or in the shared implementation is thinking of the simplest implementation you could have: a console application. You might have played a game like Peasant’s Quest: The console app is the text based adventure game version of your application. If you’re service was consumed in its simplest form, you would simply have a console based API for it that issues requests. Maybe those requests aren’t SWIM TO BOAT, but they might be CREATE USER JOHN. If I issue a request, I expect that request to be issued to the service. If the service has any exceptions or issues with my input, that business logic should be encapsulated in that service, not implemented in the UI. The service layer should be your functional application in its entirety, and anything above that layer should only assist with the display of that information.

    New computer with Windows 7 installed, I defrag, shrink, re-boot from Ubuntu LiveUSB, go to gparted and look at partitions before installing Ubuntu....for some reason Win7 is still taking up 400G of my HD! I resized partition down with gparted, exit and yes of course I can't boot into Windows. When I go to install Ubuntu in new large unallocated space I get a blank screen at the point you are asked what kind of installation you want. I have Ubuntu 12.04 LiveUSB, Windows 7 re-installation disk and driver disks also. The HDD currently has 3 allocated partitions: 'diag' fat16, 'recovery' ntfs and 'OS' ntfs which has a red '!' next to it.
