• Join me at OpenWorld 2012

  - by Michael Palmeter (Exalogic PM)

  For those of you that will be coming out to Oracle OpenWorld 2012 next ween in San Francisco, I encourage you to take a few minutes on Monday afternoon to come to my session on Oracle Exalogic. Click here for more info: CON9416 - Oracle Exalogic 2.0: Ready-to-Deploy, Mission-Critical Private Cloud My session is one of the first on Oracle Exalogic (one of the privileges of running Product Management for the product) and with that in mind it is going to be something of an introduction and overview.  The material I will present is tailored for C-level customers that are interested in the product but haven't really been exposed to it in any detail.  This is essentially the same sort of presentation I give to customers that visit Oracle HQ, and it provides context for all of the other excellent sessions that follow. During this session I will talk about: The macro-trends in the industry that are driving Exalogic strategy - IT-as-a-Service and infrastructure convergence The first two years of market success with Exalogic - who's bought it, why, and what their results have been Exalogic key features and differentiation - why it's the best possible platform for Oracle business applications and middleware How Exalogic performs, and why it is the hands-down performance champion of Enterprise cloud platforms If you haven't signed up yet, please do.  I'd love to see you there.

• Converting to a mac-book pro for multi disciplined development.

  - by DeanMc

  Hi all, I am in a bit of a bind. I have been contracted to create a small suite of applications for Android, iOS and WP7. Currently I am also on the market for a new notebook for development. Now the issue I have is I can either buy a consumer grade macbook and a laptop or I could just buy an 8gb Ram, SSD, i7 mackbook and virtualise windows 7. I have never used a mac or macbook before so before I go purchase anything I would like to know what your thoughts are on this. Has anyone any experience with this?

• Aide On a Low Memory System

  - by Jason Mock

  I have a Linux server running on a Linode.com VPS, where I'm trying to utilize aide to detect any issues. However, the nightly aide run uses up all of my available memory and swap (512MB RAM / 384MB SWAP). I've tried adding a script to /etc/cron.daily that would stop/start services using a lot of memory (apache2, mysql) during the aide run. Unfortunately, it seems like aide continued to use every available byte (including the space freed up from apache2 and mysql). Here's a graph from munin showing what happens when aide runs: Note the spike of memory usage, well into swap, when aide runs Any suggestions on tuning aide to not use so much memory, or is there an alternative to aide that doesn't behave this way?

• My desktop disappeared, how do I get it back?

  - by sunny

  I have Ubuntu 12.04 LTS. This morning when I logged into my Ubuntu, after login screen the complete desktop was empty, the only operation I could perform is right-click and open terminal. What I've tried: Ctrl+Alt+F1 unity --reset : didn't work From terminal unity --reset : didn't work And from login screen selecting Ubuntu 2D and that also didn't solve the problem. My laptop is Toshiba SA-60 onboard ATI graphic card with 1 GB RAM. Please tell me how to solve this problem. I don't want to reinstall Ubuntu as whenever I install a I/O error pops up, forget about that. I don't want to reinstall Ubuntu. Please help.

• Consultations with ATG Development at OpenWorld 2014

  - by Steven Chan (Oracle Development)

  Our OpenWorld 2014 San Francisco conference is about six weeks away.  We have a great lineup of sessions this year.  Our EBS Applications Technology track sessions are listed here, and we'll have a more-detailed article about those soon. One of the advantages of attending OpenWorld is that you can meet face-to-face with senior staff in ATG Development.  You can use these meetings to discusss your questions, requirements, plans, and deployment architectures with us. There are several options for doing this: At general sessions: collar the speaker of your choice after his or her presentation. At the Meet The Experts sessions:  these are first-come first-served round-table discussions Setting up private meetings via your Oracle account manager The last option is best if you have lots of in-depth questions or confidential details about your implementation that cannot be discussed in front of other customers.  Many of this blog's experts, including me, will be attending OpenWorld this year.  If you'd like to meet with us privately, please contact your Oracle account manager to arrange that as soon as possible.  My calendar, in particular, is already starting to fill up.  It is often completely full by the time OpenWorld starts. See you there!

• Is it only possible to display 64k vertices on the monitor with 16bit?

  - by Aufziehvogel

  I did the first 3D tutorial over at riemers.net and stumbled upon that my graphic card only supports Shader 2.0 (Reach profile in XNA) which means I can only use Int16 to store the indices (triangle to vertex). This means that I can only store 2^16 = 65536 vertices. Also I read on the internet that you should prefer 16-bit over 32-bit because not all hardware (like mine) does support 32-bit. Yet, I am wondering: Do really all game scenes get along with only so little vertices? I though already faces of people used a lot of polygons (which are made up of vertices?). It’s not relevant for me yet, but I am interested: Do game scenes use only 65536 vertices? Do you use some trade-off to display more (e.g. 64k in GPU buffer rest on RAM) Is there some method to get more into the GPU buffer? I already read on some other posts that there seems to be a limit of 64k per mesh too, so maybe you can compact stuff to meshes?

• Ubuntu perfomance issues

  - by Pelda

  I have as deafult Win 7 64b. But i get annoyed by some windows stuff so I decided to install ubuntu and learn Linux, because Win 8 is a nightmare. I have my Ubuntu 12.04 64bit installed in 100gb partition of my 1 Tb disc. My problem is that my Ubuntu feel really slower than Win 7 - even though my Win 7 are after some years of usage and they became much slower. And Ubuntu is just installed OS - I just downloaded wine and skype. It takes some time for new window to appear (its not 10 seconds, but its really slower than my windows). Sometimes my donwload get stuck (in basic ubuntu app store) Its just weird to me. I thought its because of some drivers, but I am really new to linux, so I decided to ask some1 before I screw whole system up. Specs: -6gbs of RAM - 3x2gb -3.0 ghz CPU quadcore -graphic card is HD4870 sapphire Please excuse my poor english and my addiction to windows interface. Pelda

• How do you configure mupen64plus controls?

  - by user99426

  I installed mupen64plus from the repositories using Synaptic. I like the emulator (for the most part, a couple of graphics glitches on TLOZ Ocarina of Time), especially its performance on my old machine, but I cannot figure out how to configure the controls for myself. I tried looking at Google Code's guide here but I can't find the file I need to edit and the link with the key ids isn't working, so even if I could find the file I wouldn't be able to change anything. So what I need is a resource with the key ids and where to find the file I need to edit. I am running Ubuntu 12.10 32-bit. 2GB RAM, Intel CORE 2 DUO @ 2.00GHz

• Is There a Cloud Over OpenWorld?

  - by Tony Berk

  If you have been to OpenWorld in the past, you know it can be overwhelming or at least a bit "large." If this is your first time at OpenWorld, get ready! You are in for a big (or I should say HUGE) treat. The first thing you'll notice when you get to San Francisco is there are a lot of people, buses with "Oracle" posters, large exhibit halls filled with demos, games and tchotchkes from vendors with hot new solutions, and then there are the sessions. Yes, in fact there are over 2000 sessions. How can you possibly sort through 2000 sessions to find the best 20 or so for you? Which are the 1% for you? We will try to help with some insight over the next few weeks.  I'm going start at the highest level. Up in the Clouds! Since I know many people are looking for an update on The Oracle Cloud. We will drill down into the cloud and other topics for CRM and Customer Experience sessions in the next set of posts. Below is a list of some of the Oracle executive keynotes during OpenWorld highlighting The Oracle Cloud and applications related topics (the full list is here). In these sessions you will get details on Oracle's strategy and how Oracle is changing the industry to help our customers be more efficient, effective and innovative. Sunday, September 30 6:00pm - 7:00pm Larry Ellison: Hardware and Software, Engineered to Work Together: Why it's a Different Approach Tuesday, October 2 8:45am - 9:45am Thomas Kurian: The Oracle Cloud: Oracle's Cloud Platform and Application's Strategy Tuesday, October 2 3:30pm - 4:30pm Larry Ellison: The Oracle Cloud: Where Social is Built in Thursday, October 4 9:45am - 10:45am Mark Hurd: See More, Act Faster: Oracle Business Analytics We encourage you to also join the keynotes on the Oracle Database and Cloud Infrastructure and the fascinating partner keynotes, as well.

• How to calculate maximum number of request in 128 MB VPS performance?

  - by ifdion

  I am a newbie here, please let me know if I'm using wrong webmaster terms. I am currently setting up a VPS for a multi site WordPress. The VPS uses Debian 6 LNMP setup and the DNS is being taken care by another service. Currently the VPS is running non multi site WordPress with -+ 83 MB RAM out of 128MB. As far as I know the performance is relative to the number of request, not the number of sites in the multi site setup. The question How do I calculate maximum number of request in with that setup? If the information is not enough, what other factor do I need to know? Thank you in advance.

• Ubuntu samba file and print server

  - by Gerd

  I am using an old Dell desktop PC as a samba file and print server for a Windows 7 network. The version of Unbuntu I am running is 12.04 which seems to big for the RAM and disk space I have available. Unbuntu 12.04 runs very very slow, the printing over the home network works at a quite acceptable speed. I have two problems: SLOW Ubuntu and I cannot update samba. The update manager tells me "update failed". So my two questions: Is there anything I can remove from the standard 12.04 installation to make Ubuntu run faster and should I uninstall and the reinstall samba to overcome the "update failed" problem? I hesitate, as printing and file serving works somehow and I don't want to loose that. I know I should give you more information to give me answers. But what would you need to know? I am not a natural Linux user. Windows 7 is still my home. Thanks in advance, Gerd

• Error after installing Ubuntu 12.04 using Wubi

  - by KJ50

  After using Windows Ubuntu Installer from within Windows, I am prompted to restart, so I follow the directions. When I try to start Ubuntu after restarting, the desktop background appears, but then a loading bar with this title appears. Verifying the installation configuration... While this is loading, an error window pops up that says No root file system is defined Please correct this from the partitioning menu There is only an 'Ok' button available to click, and if I click that the same error window appears. I do not know how to get to the "partitioning menu" from this state, so the only option I have is to shut down my computer. What can I do so that Ubuntu finds a "root file system"? Can I diagnose this problem via Windows? Does anyone have any insight? FYI - I am using a new ultrabook with 6GB RAM, Intel i7 3rd gen processor, and no CD/DVD drive.

• why my system gets frozen?

  - by user93019

  Is now something like 2 weeks since my system gets frozen while browsing the web, using apps, watching videos on web sites, basically using any part of my netbook, even when i'm only using one program (like the web browser) this happens. Is so frozen, that the only option i have left to do is to PRESS and hold the power button, nothing else works; I have seeing an error message telling me about a "compiz" error, but not all the times, and this happens every day, some times 2 or 3 times, during the same day. Why does this happens? how can i fix it? please help. Just to let you know i have my system up to date on 12.04 32 bits version, working on an Acer aspire AOD257, 1 Gb RAM, Intel® Atom™ CPU N570 @ 1.66GHz × 4 .

• Ubuntu 12.04 freezing on startup

  - by Frank

  Have been looking everywhere to find a solution to this problem but have yet to find a solution. I am running 64 bit 12.04 LTS on a AMD C-50 Dual core 6 gigs ram AMD Ratheon HD 6250. The problem I am experiencing is when ubuntu gets to the wallpaper screen it will sometimes freeze soon after the the image appears or shortly there after gnome loads locking up keyboard and mouse. When I try to log in via the console the same thing happens (this is as ubuntu is loading). At the moment the system is set to auto login previously it was set to ask for password but it did the same thing. Switching to from lightdm to gdm did nothing to alleviate the issue. I have never had so many issues with ubuntu I have to say 12.04 is the most buggy version yet.

• Advice on triple/quadruple-booting?

  - by professorfish

  I am currently running Windows 7 Home Premium x64 on my laptop. I would like to install more than one Linux distro, IN ADDITION TO Windows 7. How do I go about this, what do I need to be careful and aware of, is it possible? The specific distros I might eventually install: Definitely: Ubuntu (is it a good idea to install the Linux-Secure-Remix version?) Almost definitely: OpenSUSE Probably: Zorin Possibly: Arch Possibly: Fedora Possibly: FreeBSD Computer details: Successfully used WUBI for Ubuntu in the past Recently reinstalled Windows using the RECOVERY partition Windows 7 Home Premium x64 model: ASUS K53U series AMD Brazos Dual Core E450 1.65 GHz 750GB hard drive, currently partitioned into C: (300GB total, 246 GB free), D: (373GB - total, 167 GB free), and RECOVERY (the rest of the space, I think) 4GB RAM Can I be sure that GRUB will work, if WUBI has worked? In short, how do I go about triple- or quadruple-booting Windows 7, Ubuntu and other distros? What do I need to be aware of? How do I set up the partition structure? Thank you in advance

• Is there a way to force lubuntu screen resolution?

  - by za1

  I have a Dell Inspiron 4000, 900 Mhz Pentium III, 192 MB RAM,10.1 GB disk running Lubuntu 12.04. When I start the computer, and I check the display resolution, Monitor Settings claims that the max resolution is 1024x768. I then connected another monitor I had lying around, rebooted, and now the laptop monitor looks normal,and monitor settings claims that 1280x1024 is the max resolution (it is) and the other monitor doesn't turn on. (black screen) The external monitor is not broken. Is there a way to, without the external monitor, force the laptop monitor resolution to 1280x1024? (The following is another question) - How can you run commands automatically at startup? Specifically "xinput 18 118 0" (without quotes) The first question is important, I can live with typing the second one at every boot. Thanks

• I can't get a native resolution of 1920x1080 on 11.10 (AOC f22 on a Nvidia Geforce GTS 450)

  - by Mikeeeee

  I have a problem were the highest resolution I can get is 1360x769, this is a 22 inch LCD monitor with a native resolution of 1920x1080_60 I have tried numerous drivers but nothing changed I tried editing the xorg.conf scipt with no success (I am a noob with linux though). Running many commands in terminal witch I got from people with similar problems only gives me errors like "Failed to get size of gamma for output default. I get edid checksum is invalid error on boot down also. I think there maybe a communication problem between my screens EDID and ubuntu although xp and windows 7 detect my screen without any errors and automatically set native resolution. also when I am installing ubuntu I get a horrible screen flashing every few seconds until I have installed the nvidia driver. pc specks if it helps x64 os, mainboard N68PV-GS, 4 gig ram, AMD Phenom(tm) 9350e Quad-Core Processor × 4, Nvidia Geforce gts450 512mb, hard drives set up in a onboard nvidia raid array striped. realy need to get a better resolution, 1360x769 does not look nice on a 22 inch screen. ty

• Partitions and cdrom are not automounted

  - by nuit

  Provide my spec and sorry for my poor English first. MB: Gigabyte G31M-S2L (bios ver. F9) CPU: intel E5200 2G RAM HD1: WD 160G with 2 partitions (partition 1:60G, NTFS, win xp; partition 2:100G, NTFS) HD2: WD 320G with 2 partitions (partition 3:220G, NTFS; partition 4:100G, ext4, Ubuntu) Recently, I tried to install Ubuntu 12.04 Beta 2 on my desktop PC (on partition 4). At the beginning, everything looked great including the auto-mounting of partitions 1~3 and the unity (3D). However, after I deleted and re-allocated the partitions on HD2 and re-installed Ubuntu on partition 4, the partitions 1~3 are no longer auto-mounted when I logged in the desktop (and even the inserted cdrom would not be mounted either). The configurations during these two installations are all the same as default. Are there any possible reasons or solutions for this issue?

• Ubuntu 11.04 seem's like a laggy OS

  - by user772401

  I'm new to Linux/Ubuntu in general. I just dual booted the Ubuntu 11.04 w/Windows 7 on my Lenovo laptop - Intel i7 Quad Core 2Ghz, 4Gb ram, etc. etc... and for some reason Ubuntu is very laggy and slow. When I'm switching between programs (Chromium, folders, software center, etc..) it doesn't run as smooth as windows 7 (I have no more than 3 programs/windows up at a time...). I don't think it's my system requirements bkz Linux OSs are known to use low system resources. Could be a bad install or do people find it slow and laggy in general or is it my PC mfg type?? I installed it using Wubi - should I do a reinstall? I've already done all the recommended updates..

• How to make a minimal upgrade?

  - by wajed

  I use apt-get install --no-install-recommends ubuntu-desktop to install minimal desktop. I want to upgrade my system to the latest version (12.04) with it still being minimal. How do I do that? What I tried:- I tried Update Manager, and it gave me the Option to upgrade to 11.10 first, then to 12.04. What happened after I upgraded to 11.10 is that my desktop got bloated, and instead of the system using 500MB of RAM, now it uses about 1.5GB I can't even start apps anymore.
