On this panel this year we had Michael Wells from Raymond James, Joy Mathew and Venki Govindarajan from Comcast, and Serkan Karatas from Turk Telekom. Our panelists have a great mix of experiences and all are passionate about using Oracle Data Integration products to solve very complex use cases. Each panelist was given a ten minute to overview their use of our product, followed by a barrage of questions from the audience. Michael Wells spoke about using Oracle GoldenGate for heterogeneous real time replication from HP (Tandem) NonStop to SQL Server and emphasized the need for using standard naming conventions for when customers configure GoldenGate, as the practices is immensely helpful when debugging a problem. Joy Mathew and Venkat Govindarajan from Comcast described how they have used GoldenGate for over a decade and their experiences of using the product for replicating data from HP nonstop to Terdata. Serkan Karatas from Turk Telekom dove into using Oracle GoldenGate and the value of archiving data in extremely large databases, which in Turk Telekoms case resulted in a 1 month ROI for the entire project. Thanks again to our panelist and audience participants for making the session interactive and informative.  For Wednesday we have a number of sessions available to attendees plus two hands-on labs, which I have listed below.   If you are unable to attend our hands-on lab for Oracle GoldenGate Veridata, it is available online at youtube.com.

• Installation of 11.10 on new drive (no OS)

  - by Jeffrey Vincent

  I have a Dell Dimension 600 XPS Phoenix BIOS version A03, the original HD crashed and burned. Dell didn't send OS disks (was on the original drive and no back up disks), so I am trying to install Ubuntu 11.10 on the new drive. The new drive is a Western Digital 1TB. I formatted the new drive by putting it in an enclosure and formatting it with Windows 7 on my HP system. When I put the cd in the cdrom it boots to the cd with the Advanced user screen (won't boot into the usually Windows GUI). When I try to install (or run from live Cd) I get the same error message. Same with trying the various boot options. The message is: VFS: cannot open root device "(NULL)" or unknown-block(8,1) Please append a correct "root=" boot option: Here are the available partitions: Kernal Panic- not syncing: VFS: Unable to mount rootfs on unknown-block(8,1) and then it lists Trace messages then freezing. Any help or suggestions are appreciated in advance.

• How to disable laptop internal keyboard

  - by Abhijit Navale

  I am using external usb keyboard. I want to disable laptop's internal keyboard using software. I know that i can just remove the internal keyboards wire and disconnect it physically, but i wanted to disable it using software so that later I can enable it by just executing a command in terminal easily. I am talking about disabling the keyboard and NOT the keyboard layout. I am having Hp-Compaq Presario A965 TU Laptop Intel Centrino Core 2 Duo(Freq. 2 GHz). I am using 64 bit Ubuntu Lucid Lynx.

• Disable ATI Radeon graphics card and use intel graphics (switcheroo unavailable)

  - by user92356

  So I have a HP Envy with ATI Radeon 5450 + intel switchable graphics. I think (though I'm not sure) that the Radeon is running right now on Ubuntu 12.04 (because my laptop is making too much noise when I'm doing something non gpu intensive like word processing, or web browsing). So what I want to do is disable the ATI Radeon and use the Intel instead. I looked around and it seems all the solutions use switcheroo, but I dont have it on my computer! I think this happened because I tried installing the proprietary driver (fglrx). Any and all help is 200% appreciated, thank you

• Xubuntu 14.04 black screen after monitor off/on

  - by Sampo Smolander

  I have a HP desktop machine with Ubuntu 14.04, with also Xubuntu and Gnome desktops installed. I mostly use the Xubuntu session. When using the Xubuntu session, when I power off my monitor, and power it back on, the screen stays black and I cannot do any work. With ctrl-alt-f6 I can open another virtual terminal, and then the screen works again, but if I to go back to the desktop session with ctrl-alt-f7, all I have is a black screen. But, if I login to Unity (the Ubuntu default session), or to Gnome, and turn the monitor off and back on, everything works ok. Also, if I log out, and while in the lightdm greeter, turn the monitor off and back on, everything works ok. What could be the cause for this, and how to fix this?

• cant get ubuntu to work with windows 8

  - by John Mark High

  ive been trying to dual boot Ubuntu with windows 8 but so far I haven't been able too. the laptop im using is a HP Pavilion g6-2240sa pre-installed with windows 8. ive made the bootbale USB with Ubuntu 12.10, it installs but when I restart the computer boot straight into windows, no grub boot options. I can get into Ubuntu once by doing an advanced restart and booting from the Ubuntu partition. I can use Ubuntu fine but once I restart or shutdown, I do the advanced restart again and the Ubuntu partition is now gone and I have to reinstall. i used this tutorial to install Ubuntu, http://www.youtube.com/watch?v=wNCSbTyUzoM After i have to reinstall and still no grub boot menu, i used the boot repair to re-install it. once i rebooted the computer it went straight to windows again and the Ubuntu partition was gone. can i dual boot windows 8 and unbuntu 12.10 with the grub so i can pick what OS to boot into when the computer is starting, and without the partition going AWOL???? Thanks in advance

• how to recover deleted ntfs patition with data entirely while installing ubuntu 13.04

  - by Anson Varghese

  I've installed ubuntu 13.04 onto my hp 2231tx computer. During installation all of my data was erased. I didn't know all of my three partitions would be deleted. I was shocked after finding out that all of my personal data was erased. I didn't know what to do to resolve this problem so I search google for an answer. I found a program called testdisk and I used it to recover about half of my data. Among this data weren't my personal photos and videos. Is there a way to recover the other half?

• Lack of Transparency in the Supply Chain Results in Inconsistent Reporting on Conflict Minerals

  - by Terri Hiskey

  May 31, 2014 was the official deadline for U.S.-listed companies to disclose use of conflict minerals to the SEC. Of the estimated 6,000 companies that were required to file audits of their tin, gold, tungsten or tantalum in their products, only 1,300 filed reports, and these results have revealed the ongoing challenges that many manufacturers are having complying with this legislation. An article authored by IDC analyst Heather Ashton,"Conflict Minerals Reporting Passes a Notable Milestone" notes that many leading companies such as Intel, Apple and HP filed their reports ahead of the deadline, but other companies are struggling with trying to trace their supply chain back to raw materials, especially as many non-U.S. based suppliers have no legal requirement to comply with the law since they are not U.S.-listed companies. This has resulted in widely varying levels of reporting from company to company. Check out the full article here. Are your customers experiencing the same pains?

• DOT implementation

  - by Denis Ermolin

  I have some DOT(damage over time) implementation problems. My game runs on 30 FPS speed. Current implementation is: let's say hero cast spell which make 1 damage per second. So on every frame i do (pseudo code): damage_done = getRandomDamage() * delta_time; I accumulate damage and when it becomes more then 0 then subtract rounded damage from current health and so on. With 30 FPS and 1 DPS it will be 1/33 = 0.05... We know that floats a not precise enough to sum 30 circulating decimals and have exact 1 in the end. But HP is discrete value and that's why 1 DPS will not have 1 damage after 1 second because value will be 0.9999..... It's not so big deal when you have 100000 DPS - +/- 1 damage will not be noticeable. But if i have 1, 5 DPS? How modern RPG's implemented DOT's?

• Getting vga_switcheroo with ATI Mobility Radeon 5650 HD to work

  - by stevejb

  Hello! I have a new HP dv7 laptop with ATI Mobility Radeon HD 5650 graphics card, and also Intel graphics (switchable). I have done the following and want to understand what is going on with my graphics driver Resized windows 7 and did fresh install of 10.10 Booted into 10.10 and things seemed to be working okay Enabled ATI graphics, and was clearly working on the ATI rather than Intel GPU (desktop cube worked) Rebooted, got an error that modprobe could not load modules.dep, and also something about i915 symbols Rebooted into recovery mode, modified xorg.conf to remove the mention of fglrx Rebooted, and the errors show, but then x starts but clearly in intel graphics I would ideally like to be able to switch between the ATI and Intel graphics, a la vga_switcheroo. My first problem seems to be that the folder /sys/kernel/debug/vgaswitcheroo does not exist, hinting at some kind of kernel issue. What can I do to get this available? Thanks!

• unix career in programming

  - by mnunna

  I am currently working on a HP-UX platform and my role as a prod support team member involves mostly to write shell scripts. But I want to branch out into core systems programming in unix. A quick search on the internet threw no "unix systems programming jobs" in my area. I'm confused as what to do. I really would like to continue with unix as my core competency, but unix jobs are mostly of sys admin/ prod support type, of which I do not want a part of. Can anyone of you give me an informed advice on the career oppurtinities that await unix professionals?? Any advice would be appreciated.

• Cannot sleep/standby in Ubuntu 12.04

  - by mstaessen

  Yesterday, I installed Ubuntu 12.04 Desktop i386 on my netbook (HP Mini 311c). I am unable to use the sleep mode. When I press the suspend button (or do sudo pm-suspend), the screen flickers but the computer does not power off. Even worse, the screen comes back up and I'm back where I left off. Hibernating does work (although it is not available in Power Management). I have to use pm-hibernate to make that work. I'm using the 3.2.0.20 kernel and Gnome 3.3.92 (Unity, especially compiz, is a resource hog). Before Ubuntu 12.04, I was using Mint Linux 12 with the 3.0 kernel and everything worked fine back then. Any help is much appreciated because this is driving me crazy.

• Unity Desktop not loading and ccsm method not working

  - by slimy-spork

  I installed Ubuntu 13.04 x86_64 on my HP Pavillion DV7-6c60us. It installs fine and works until I update. I run the software updater and reboot as it requests after. When my computer comes back on I get the desktop background but the rest of the Unity desktop doesn't load. I've tried the ccsm method and re-enabling but it just de-enables itself. I've also tried installing the gnome desktop but that does nothing for me either. I really want to switch to Ubuntu but this is causing issues. P.S. I've also tried using 12.10 and 12.04 with no dice.

• Icon zoom on gnome panel with mouseover?

  - by brent.with.a.mustache

  I'm actually quite surprised that I couldn't find any information regarding this question through simple google-ing; I would think that it was something of a no-brainer kind of question. I'm basically trying to figure out if there's any way to have the icons in the side panel/favorites bar magnify as you mouseover them, much like you'd see in any the popular launcher programs (i.e. rocket dock or apple's launcher)? I'm on a netbook with a rather limited amount of screen real estate to work with, so the icons depicting my "favorite applications" have been reduced to a permanent, unsatisfying handful of pixels. Again, it seems to me that this should be a fairly obvious feature to include in the options for the panel, so I'm hoping that there's an easy solution. Unfortunately, I haven't found any way to make this happen, so any help would be appreciated. Here's a screenshot :squint: http://i.imgur.com/OpMIF.jpg -- ubuntu 11.10; gnome 3; hp mini 110

• how to find available wireless networks

  - by Quinn

  I'm using an HP Pavilion dv6000 I've looked at other answers similar to this question how ever when I look at my network symbol it doesn't say anything that the answer below says "Make sure that your wifi hardware switch is on or not. It is either F2 or F12 or near to it. Once the switch is enabled, there is a small fan-like applet on the top panel (Gnome Network Manager), fourth from the right. Click on it and if there is no tick mark on the option 'Enable Wireless', enable it. Wait till your wifi connection name appears." it how says 'Enable Networking' my wi-fi switch is on and I've tried using terminal to kill the applet as another answer suggests trying. Does anyone have any other ideas that might help? Just in case anybodies curious as to how I'm posting this I'm on my other ubuntu laptop that's running an older version.

• How can I calibrate my printer using the LaTeX test page?

  - by Chris

  I am trying to print a LaTeX compiled document but my printer doesn't print the top part. It seems that the top part is outside of the printing range. To debug this problem I have printed the LaTeX test page (/usr/share/texmf-texlive/tex/latex/base/testpage.tex) and it turns out that my printer is placing the content about 4.5mm closer to the top of the page than it should. How can I calibrate my printer/driver so that it will place the content where it is supposed to go? I am using an HP OfficetJet 7300 printer with hplip.
