  • Le Logiciel Libre – Omniprésent dans le secteur public

    - by gravax
    NOTE : Cet article a servi de base à du contenu publié en Juin 2011 dans le magazine Acteurs Publics. Créé il y a plusieurs décennies déjà, pour répondre à un besoin de partage de savoir, et de compétences, le Logiciel Libre existe sous plusieurs appellations, à l'origine anglo-saxonnes, dont « Free Software » et « Open Source » sont les plus utilisées. En Anglais, le mot « Free » pouvant signifier à la fois libre et gratuit, cela a créé une certaine confusion qui n'existe pas en Français avec le mot « libre ». Du coup, on voit souvent l’acronyme FOSS ou FLOSS, pour « Free, Libre, Open Source Software » afin d'éliminer l’ambiguïté. De nos jours, dans le secteur public, le logiciel libre est, depuis, devenu omniprésent. Il répond à plusieurs besoins critiques dont le contrôle des coûts, le choix (de partenaire, de logiciel, de fonctionnalités), la liberté de pouvoir modifier les applications pour les adapter à ses propres besoins, la sécurité provenant du fait que de nombreux développeurs et utilisateurs ont pu contrôler la qualité du code. Un autre aspect très présent dans les logiciels libres et l'adhérence quasi-systématique aux standards de l'industrie, qui garantit une intégration simple et facile au système d'information existant. Il y a cependant des éléments à prendre en compte lors des choix de logiciels libres stratégiques. Si l'aspect coûts est clairement un élément de choix qui peut conduire aux logiciels libres, il est principalement dû au fait qu'un logiciel libre existe souvent en version gratuite, librement téléchargeable. Mais ceci n'est que le le sommet de l'iceberg. Lors de la mise en production de logiciels il va falloir s'entourer de services dont l'intégration, où les possibilités de choix d'un partenaire seront d'autant plus grandes que le logiciel choisi est populaire et connu, ce qui conduira à des coups tirés vers le bas grâce à une concurrence saine. Mais il faudra aussi prévoir le support technique. La encore, la popularité du logiciel choisi augmentera la palette de prestataires de support possible. Le choix devra se faire suivant des critères très solides, et en particulier la capacité à s'engager sur des niveaux de service, la disponibilité 24 heures sur 24, 7 jours sur 7 (le pays ne s’arrête pas de fonctionner le week-end ou la nuit), et, éventuellement, la couverture géographique correspondant aux métiers que l'on exerce (un pays comme la France couvrant avec ses DOM et ses TOM une grande partie des fuseaux horaires et zones géographiques de la planète). La plus part des services publics, que ce soit éducation, santé, ou gouvernement, utilisent déjà des logiciels libres. On les retrouve coté infrastructure, avec des produits comme la base de données MySQL, fortement appréciée dans le monde de l'éducation pour construire des plate-formes d'e-éducation en conjonction avec d'autres produits libres tels Moodle, ou GlassFish, le serveur d'applications très prisé des développeurs pour son adhérence au standard Java EE version 6 et sa simplicité de mise-en-œuvre. Linux est extrêmement présent comme système d'exploitation libre dans le datacenter, mais aussi sur le poste de travail. On retrouve des outils de virtualisation tels Oracle VM, issu de Xen, dans le datacenter, et VirtualBox sur le poste du développeur. Avec une telle palette de solutions et d'outils dans le monde du Logiciel libre, Oracle se apporte au secteur public des réponses ciblées, efficaces, aux besoins du marché, y compris en matière de support technique et qualité de service associée.

  • The enterprise vendor con - connecting SSD's using SATA 2 (3Gbits) thus limiting there performance

    - by tonyrogerson
    When comparing SSD against Hard drive performance it really makes me cross when folk think comparing an array of SSD running on 3GBits/sec to hard drives running on 6GBits/second is somehow valid. In a paper from DELL (http://www.dell.com/downloads/global/products/pvaul/en/PowerEdge-PowerVaultH800-CacheCade-final.pdf) on increasing database performance using the DELL PERC H800 with Solid State Drives they compare four SSD drives connected at 3Gbits/sec against ten 10Krpm drives connected at 6Gbits [Tony slaps forehead while shouting DOH!]. It is true in the case of hard drives it probably doesn’t make much difference 3Gbit or 6Gbit because SAS and SATA are both end to end protocols rather than shared bus architecture like SCSI, so the hard drive doesn’t share bandwidth and probably can’t get near the 600MiBytes/second throughput that 6Gbit gives unless you are doing contiguous reads, in my own tests on a single 15Krpm SAS disk using IOMeter (8 worker threads, queue depth of 16 with a stripe size of 64KiB, an 8KiB transfer size on a drive formatted with an allocation size of 8KiB for a 100% sequential read test) I only get 347MiBytes per second sustained throughput at an average latency of 2.87ms per IO equating to 44.5K IOps, ok, if that was 3GBits it would be less – around 280MiBytes per second, oh, but wait a minute [...fingers tap desk] You’ll struggle to find in the commodity space an SSD that doesn’t have the SATA 3 (6GBits) interface, SSD’s are fast not only low latency and high IOps but they also offer a very large sustained transfer rate, consider the OCZ Agility 3 it so happens that in my masters dissertation I did the same test but on a difference box, I got 374MiBytes per second at an average latency of 2.67ms per IO equating to 47.9K IOps – cost of an 240GB Agility 3 is £174.24 (http://www.scan.co.uk/products/240gb-ocz-agility-3-ssd-25-sata-6gb-s-sandforce-2281-read-525mb-s-write-500mb-s-85k-iops), but that same drive set in a box connected with SATA 2 (3Gbits) would only yield around 280MiBytes per second thus losing almost 100MiBytes per second throughput and a ton of IOps too. So why the hell are “enterprise” vendors still only connecting SSD’s at 3GBits? Well, my conspiracy states that they have no interest in you moving to SSD because they’ll lose so much money, the argument that they use SATA 2 doesn’t wash, SATA 3 has been out for some time now and all the commodity stuff you buy uses it now. Consider the cost, not in terms of price per GB but price per IOps, SSD absolutely thrash Hard Drives on that, it was true that the opposite was also true that Hard Drives thrashed SSD’s on price per GB, but is that true now, I’m not so sure – a 300GByte 2.5” 15Krpm SAS drive costs £329.76 ex VAT (http://www.scan.co.uk/products/300gb-seagate-st9300653ss-savvio-15k3-25-hdd-sas-6gb-s-15000rpm-64mb-cache-27ms) which equates to £1.09 per GB compared to a 480GB OCZ Agility 3 costing £422.10 ex VAT (http://www.scan.co.uk/products/480gb-ocz-agility-3-ssd-25-sata-6gb-s-sandforce-2281-read-525mb-s-write-410mb-s-30k-iops) which equates to £0.88 per GB. Ok, I compared an “enterprise” hard drive with a “commodity” SSD, ok, so things get a little more complicated here, most “enterprise” SSD’s are SLC and most commodity are MLC, SLC gives more performance and wear, I’ll talk about that another day. For now though, don’t get sucked in by vendor marketing, SATA 2 (3Gbit) just doesn’t cut it, SSD need 6Gbit to breath and even that SSD’s are pushing. Alas, SSD’s are connected using SATA so all the controllers I’ve seen thus far from HP and DELL only do SATA 2 – deliberate? Well, I’ll let you decide on that one.

  • Partner Blog: Hub City Media Introduces iPad Application for Oracle Identity Analytics

    - by Tanu Sood
    About the Writer:Steve Giovannetti is CTO of Hub City Media, Inc., a company that specializes in implementation and product development on the Oracle Identity Management platform. Recently, Hub City Media announced the introduction of iPad application IdentityCert for Oracle Identity Analytics. This post explore the business use cases and application of IdentityCert.Hub City Media(HCM) has been deploying certification solutions based on Oracle Identity Analytics since it first appeared on the market as Vaau RBACx. With each deployment we've seen the same pattern repeat time and time again:1. Customers suffering under the weight of manual access certification regimens deploy Oracle Identity Analytics (OIA) for automated certification. 2. OIA improves the frequency, speed, accuracy, and participation of certifications across the organization. 3. Then the certifiers, typically managers and supervisors, ask, “Is there any easier way to do these certifications offline?”The current version of OIA has a way to export certification data to a spreadsheet.  For some customers, we've leveraged this feature and combined it with some of our own custom code to provide a solution based on spreadsheet exports and imports.  Customers export the certification to Microsoft Excel, complete it, and then import the spreadsheet to OIA. It worked well for offline certification, but if the user accidentally altered the format of the spreadsheet, the import of the data could fail. We were close to a solution but it wasn’t reliable.Over the past few years, we've seen the proliferation of Apple iOS devices, specifically the iPhone and iPad, in the enterprise.  As our customers were asking for offline certification, we noticed the same population of users traditionally responsible for access certification, were early adopters of the iPad. The environment seemed ideal for us to create an iPad application to support offline certifications using Oracle Identity Analytics. That’s why we created IdentityCert™.IdentityCert allows users to view their analytics dashboard, complete user certifications, and resolve policy violations with OIA, from their iPads.The current IdentityCert analytics dashboard displays the same charts that are available in the Oracle Identity Analytics product. However, we plan to expand the number of available analytics in future releases.The main function of IdentityCert is user certification which can be performed quickly and efficiently using a simple touch interface. Managers tap into a certification, use simple gestures to claim users and certify their access.  Certifications can be securely downloaded to IdentityCert and can be completed with or without a network connection. The user can upload the completed certifications once they are connected to a cellular or wi-fi network.Oracle Identity Analytics can generate policy violation notifications based on detective scans of identity warehouse or via preventative analysis of identity access requests. IdentityCert allows users to view all policy violations, resolve, or delegate them to appropriate users. IdentityCert also analyzes the policy violation expression and produces more human friendly descriptions of the policy violation which improves the ability of users to resolve the violation. IdentityCert can be deployed quickly into a customer's environment. It is deployed with Hub City Media's ID Services to connect Oracle Identity Analytics securely with the iPad application.Oracle Identity Management 11g R2 is an important evolutionary release. Oracle's Identity Management suite has more characteristics of a cohesive platform. This platform provides an integrated set of identity services that can be used to protect, manage, and audit security within the enterprise. At HCM we take the platform concept a step further and see it as an opportunity to create unique solutions for Oracle Identity Management customers. IdentityCert is our commitment to this platform. You can download IdentityCert from the Apple iOS App Store today. It includes a demo dataset that you can use to explore the functions of the product without any server infrastructure. Download it. Give it a try. We would appreciate your interest and welcome any feedback.Resources:Press Release: Hub City Media Introduces iPad Application IdentityCert™ for Oracle Identity AnalyticsApp Store Download: http://bit.ly/IdentityCertOracle Identity Governance Suite

  • Top 10 Linked Blogs of 2010

    - by Bill Graziano
    Each week I send out a SQL Server newsletter and include links to interesting blog posts.  I’ve linked to over 500 blog posts so far in 2010.  Late last year I started storing those links in a database so I could do a little reporting.  I tend to link to posts related to the OLTP engine.  I also try to link to the individual blogger in the group blogs.  Unfortunately that wasn’t possible for the SQLCAT and CSS blogs.  I also have a real weakness for posts related to PASS. These are the top 10 blogs that I linked to during the year ordered by the number of posts I linked to. Paul Randal – Paul writes extensively on the internals of the relational engine.  Lots of great posts around transactions, transaction log, disaster recovery, corruption, indexes and DBCC.  I also linked to many of his SQL Server myths posts. Glenn Berry – Glenn writes very interesting posts on how hardware affects SQL Server.  I especially like his posts on the various CPU platforms.  These aren’t necessarily topics that I’m searching for but I really enjoy reading them. The SQLCAT Team – This Microsoft team focuses on the largest and most interesting SQL Server installations.  The regularly publish white papers and best practices. SQL Server CSS Team – These are the top engineers from the Microsoft Customer Service and Support group.  These are the folks you finally talk to after your case has been escalated about 20 times.  They write about the interesting problems they find. Brent Ozar – The posts I linked to mostly focused on the relational engine: CPU, NUMA, SSD drives, performance monitoring, etc.  But Brent writes about a real variety of topics including blogging, social networking, speaking, the MCM, SQL Azure and anything else that seems to strike his fancy.  His posts are always well written and though provoking. Jeremiah Peschka – A number of Jeremiah’s posts weren’t about SQL Server.  He’s very active in the “NoSQL” area and I linked to a number of those posts.  I think it’s important for people to know what other technologies are out there. Brad McGehee – Brad writes about being a DBA including maintenance plans, DBA checklists, compression and audit. Thomas LaRock – I linked to a variety of posts from PBM to networking to 24 Hours of PASS to TDE.  Just a real variety of topics.  Tom always writes with an interesting style usually mixing in a movie theme and/or bacon. Aaron Bertrand – Many of my links this year were Denali features.  He also had a great series on bad habits to kick. Michael J. Swart – This last one surprised me.  There are some well known SQL Server bloggers below Michael on this list.  I linked to posts on indexes, hierarchies, transactions and I/O performance and a variety of other engine related posts.  All are interesting and well thought out.  Many of his non-SQL posts are also very good.  He seems to have an interest in puzzles and other brain teasers.  Michael, I won’t be surprised again!

But there remains a lack of understanding about SOA Governance. DevOps Basics: Track Down High CPU Thread with ps, top and the new JDK7 jcmd Tool | Frank Munz "The approach is very generic and works for WebLogic, Glassfish or any other Java application," say Frank Munz. "UNIX commands in the example are run on CentOS, so they will work without changes for Oracle Enterprise Linux or RedHat. Creating the thread dump at the end of the video is done with the jcmd tool from JDK7." Frank has captured the process in the posted video.

    The results are in... Listed below are the Top 10 most popular items shared via the OTN ArchBeat Facebook Page for the month of September 2012.

Just a full day of technical sessions and peer interaction focused on using Oracle technologies in today's cloud and SOA architectures. The event is free, but seating is limited, so register now. Thursday October 25, 2012. 8:00 a.m. – 5:00 p.m. Sofitel Los Angeles, 8555 Beverly Boulevard, Los Angeles, CA 90048. Oracle Fusion Middleware Security: Attaching OWSM policies to JRF-based web services clients "OWSM (Oracle Web Services Manager) is Oracle's recommended method for securing SOAP web services," says Oracle Fusion Middleware A-Team member Andre Correa. "It provides agents that encapsulate the necessary logic to interact with the underlying software stack on both service and client sides. Such agents have their behavior driven by policies. OWSM ships with a bunch of policies that are adequate to most common real world scenarios." His detailed post shows how to make it happen. Oracle 11gR2 RAC on Software Defined Network (SDN) (OpenvSwitch, Floodlight, Beacon) | Gilbert Stan "The SDN [software defined network] idea is to separate the control plane and the data plane in networking and to virtualize networking the same way we have virtualized servers," explains Gil Standen. "This is an idea whose time has come because VMs and vmotion have created all kinds of problems with how to tell networking equipment that a VM has moved and to preserve connectivity to VPN end points, preserve IP, etc." H/T to Oracle ACE Director Tim Hall for the recommendation.

  • Review&ndash;Build Android and iOS apps in Visual Studio with Nomad

    - by Bill Osuch
    Nomad is a Visual Studio extension that allows you build apps for both Android and iOS platforms in Visual Studio using HTML5. There is no need to switch between .Net, Java and Objective-C to target different platforms - write your code once in HTML5 and build for all common mobile platforms and tablets. You have access to the native hardware functions (such as camera and GPS) through the PhoneGap library, UI libraries such as jQuery mobile allow you to create an impressive UI with minimal work. Nomad is still in an early access beta stage, so the documentation is a bit sparse. In fact, the only documentation is a simple series of steps on how to install the plug-in, set up a project, build and deploy it. You're going to want to be a least a little familiar with the PhoneGap library and jQuery mobile to really tap into the power of this. The sample project included with the download shows you just how simple it is to create projects in Visual Studio. The sample solution comes with an index.html file containing the HTML5 code, the Cordova (PhoneGap) library, jQuery libraries, and a JQuery style sheet: The html file is pretty straightforward. If you haven't experimented with JQuery mobile before, some of the attributes (such as data-role) might be new to you, but some quick Googling will fill in everything you need to know. The first part of the file builds a simple (but attractive) list with some links in it: The second part of the file is where things get interesting and it taps into the PhoneGap library. For instance, it gets the geolocation position by calling position.coords.latitude and position.coords.longitude: ...and then displays it in a simple span: Building is pretty simple, at least for Android (I'm not an iOS developer so I didn't look at that feature) - just configure the display name, version number, and package ID. There's no need to specify Android version; Nomad supports 2.2 and later. Enter these bits of information, click the new "Build for Android" button (not the regular Visual Studio Build link...) and you get a dialog box saying that your code is being built by their cloud build service (so no building while away from a WiFi signal apparently). After a couple minutes you wind up with a .apk file that can be copied over to your device. Applications built with Nomad for Android currently use a temporary certificate, so you can test the app on your devices but you cannot publish them in the Google Play Store (yet). And I love the "success" dialog box: Since Nomad is still in Beta, no pricing plans have been announced yet, so I'll be curious to see if this becomes a cost-effective solution to mobile app development. If it is, I may even be tempted to spring for the $99 iOS membership fee! In the meantime, I plan to work on porting some of my apps over to it and seeing how they work. My only quibble at this time is the lack of a centralized documentation location - I'd like to at least see which (if any) features of JQuery and PhoneGap are limited or not supported. Also, some notes on targeting different Android screen sizes would be nice, but it's relatively easy to find jQuery examples out on the InterWebs. Oh well, trial and error! You can download the Nomad extension for Visual Studio by going to their web site: www.vsnomad.com. Technorati Tags: Android, Nomad

  • Sparse virtual machine disk image resizing weirdness?

    - by Matt H
    I have a partitioned virtual machine disk image created by vmware. What I want to do is resize that by 10GB. The file size is showing as 64424509440. Or 60GB. So I ran this: dd if=/dev/zero of=./win7.img seek=146800640 count=0 It ran without errors and I can verify the new size is in fact 75161927680 bytes or 70GB. This is where it gets a little odd. I started the guest domain in xen which is a Windows 7 enterprise machine. What I was expecting to see in diskmgmt.msc is 2 partitions. 1 system partition at the start of around 100MB and near 60GB partition (which is C drive) followed by around 10GB of free space. Actually what I saw was a 70GB partition!?! That confused me... so I decided to run the Check Disk which when you set it on the C drive it asks you to reboot so it'll run on boot. So I did that and during the boot it ran the checks. It got all the way through stage 3 and didn't show any errors at all. Looked at the partitions in disk manager and now C drive has shrunk back to 60GB and there is no free space. What gives? Ok, I thought I'd try mounting it under Dom0 and examining it with fdisk. This is what I get when mounted sudo xl block-attach 0 tap:aio:/home/xen/vms/otoy_v1202-xen.img xvda w sudo fdisk -l /dev/xvda Disk /dev/xvda: 64.4 GB, 64424509440 bytes 255 heads, 63 sectors/track, 7832 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x582dfc96 Device Boot Start End Blocks Id System /dev/xvda1 * 1 13 102400 7 HPFS/NTFS Partition 1 does not end on cylinder boundary. /dev/xvda2 13 7833 62810112 7 HPFS/NTFS Note the cylinder boundary comment. When I run sudo cfdisk /dev/xvda I get: FATAL ERROR: Bad primary partition 1: Partition ends in the final partial cylinder Press any key to exit cfdisk So I guess this is a bigger problem than first thought. How can I fix this? EDIT: Oops, the cylinder boundary thing is not a problem at all since disks have used LBA etc. So that threw me for a moment... still the problem exists... Now this output looks a little different. sudo sfdisk -uS -l /dev/xvda Disk /dev/xvda: 7832 cylinders, 255 heads, 63 sectors/track Units = sectors of 512 bytes, counting from 0 Device Boot Start End #sectors Id System /dev/xvda1 * 2048 206847 204800 7 HPFS/NTFS /dev/xvda2 206848 125827071 125620224 7 HPFS/NTFS /dev/xvda3 0 - 0 0 Empty /dev/xvda4 0 - 0 0 Empty BTW: I do have a backup of the image so if you help me mess it up that's ok. EDIT: sudo parted /dev/xvda print free Model: Xen Virtual Block Device (xvd) Disk /dev/xvda: 64.4GB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 32.3kB 1049kB 1016kB Free Space 1 1049kB 106MB 105MB primary ntfs boot 2 106MB 64.4GB 64.3GB primary ntfs 64.4GB 64.4GB 1049kB Free Space Cool. Linux is showing free space is 10GB which is what I expect. The problem is windows isn't seeing this?

  • Ubuntu keyboard shortcuts - two-part question

    - by Don
    Background: I come from a Windows background and just started dual-booting Ubuntu (my first Linux experience) about 4 days ago. So my systems are Windows 7/Ubuntu 12.04, and so far I'm loving Ubuntu. I am a dedicated mouse-abolitionist (trackpads are hell) and do most of my browsing and navigation with keyboard shortcuts. However, on switching to Ubuntu, a lot of my keyboard shortcuts are gone, and my productivity has resultantly taken a huge hit anytime I am using Ubuntu. Problem 1: My computer was designed to display on-screen notifications for a second when I hit caps-lock or num-lock, and there are no constant indicators of the lock status (LEDs, etc). In Ubuntu, the keys still worked, but the notifications were gone. Googling got me a tutorial on key-binding(Compiz) and scripts, so now I have capslock and numlock running this script: #!/bin/bash icon="/usr/share/icons/gnome/scalable/devices/keyboard.svg" case $1 in 'scrl') mask=3 key="Scroll" ;; 'num') mask=2 key="Num" ;; 'caps') mask=1 key="Caps" ;; esac value=$(xset q | grep "LED mask" | sed -r "s/.*LED mask:\s+[0-9a-fA-F]+([0-9a-fA-F]).*/\1/") if [ $(( 0x$value & 0x$mask )) == $mask ] then output="$key Lock" output2="On" else output="$key Lock" output2="Off" fi notify-send -i $icon "$output" "$output2" -t 1000 But, whether turning it off or on, the notifications always say that I have turned it on. Is there an easy fix for this, or an easier way to work it to get it do display the CORRECT notifications? Problem 2: I'm not sure if this is because of my keyboard or Ubuntu. In Windows, I use Chrome and use the ctrl+pgUp/pgDwn shortcuts quite a bit to switch between tabs. On my keyboard, I can enter pgUp and pgDwn by either disabling NumLock and hitting 9 or 3 respectively on the 10key. Alternately I can hold the fn key and hit up or down arrow. The first method is the one I very heavily relied upon, and it works in Firefox for Ubuntu, but not in Chrome nor in Chromium. The second method (ctrl + fn + up/down) works fine in Chrome. However, I'd dearly like to find a method to make the first method work. Any suggestions? Thanks in advance for your help. Update: @julien: I've checked the keyboard layout options - I didn't find anything that seemed useful for this goal. @Marty: The script runs once when the button is pressed. In Compiz, I've tied those two keys to the script, so when I press the button, it runs the script with the button pressed as a parameter. Update: @elmicha: Thanks. That one works a lot better, and it even pops an icon into the status bar when caps lock is on. There's still a very slight problem in that if I quickly tap the key twice, the image will show that it has been turned on and then turned off, and the notifaction will come and go from my status area, but the text of both notifications will be "Caps Lock on". Same with Num Lock. However, if the time between presses is long enough for the first notification to disappear, everything displays correctly. Given how quickly the notifications disappear, I don't expect this will pose too much of a problem for me.

  • OpenWorld: Our (Road) Maps are Looking Good!

    - by Tony Berk
    Wow, only one (or two) days down at Oracle OpenWorld! Are you on overload yet? I'm still trying to figure out how to be in 3 sessions at the same time... I guess everyone needs to prioritize! There was a lot to see in Monday's sessions, especially some great forward-looking roadmap sessions. In case you aren't here or you decided to go to other sessions, this is my quick summary of what I could capture from a couple of the roadmaps: In the Fusion CRM Strategy and Roadmap session, Anthony Lye provided an overview of the Fusion CRM strategy including the key design principles of 3 E's: Easy, Effective and Efficient. After an overview of how Oracle has deployed Fusion CRM internally to 25,000 users worldwide, Anthony discussed the features coming in the next release, the releases in the next 12 months and beyond. I can't detail too much since you haven't read Oracle's Safe Harbor statement, but check out Fusion Tap and look for new features and added functionality for sales prediction, marketing, social and integration with a number of the key Customer Experience products.  In the Oracle RightNow CX Cloud Service Vision and Roadmap session, Chris Hamilton presented the focus areas for the RightNow product. As a result of the large increase in development resources after the acquisition, the RightNow CX team is planning a lot of enhancements to the functionality, infrastructure and integrations. As a key piece of the Oracle Customer Experience (CX) strategy, RightNow will be integrated with Oracle Social Network, Oracle Commerce (ATG and Endeca), Oracle Knowledge, Oracle Policy Automation and, of course, further integration with Fusion Sales and Marketing. Look forward to seeing more on the Virtual Assistant, Smart Interaction Hub and Mobility. In addition to the roadmaps, I was looking forward to hearing from Oracle CRM customers. So, I sat in on two great Siebel customer panels: The Maximizing User Adoption Rates for Siebel Sales and Siebel Partner Relationship Management panel consisted of speakers from CSL Behring, McKesson and Intuit. It was great to get an overview of implementations for both B2B and B2C companies. It was great hearing that all of these companies have more than 1,000 sales users (Intuit has 4,000) and how the 360 degree view of the customer in Siebel is helping these customers improve their customers' experience (CX). They are all great examples of centralized implementations which have standardized processes across the globe and across business units.  Waste Management, Farmers Insurance and the US Citizenship & Immigration Services presented in the Driving Great Customer Experiences with Siebel Service Applications session. Talk about serving large customer bases! Is it possible that Farmers with only 10 million households is the smallest of these 3? All of them provided great examples of how they are improving the customer experience (CX) including 60-70% improvements in efficiency or reducing the number of applications the customer service reps (CSRs) need to use from 10 to 1 (Waste Management) and context aware call transfers to avoid the caller explaining their issue 3 times (USCIS). So that's my wrap up of only 4 sessions from Monday. In between sessions, I stopped by the Oracle DEMOgrounds and CRM Pavilion to visit with a group of great partners and see the products and partner integrations in action. Don't miss a recap of Mark Hurd's Keynote. I can't believe there were another 40+ sessions covering CRM, Fusion, Cloud, etc. that I missed today! Anyone else see any great sessions?

The focus of my talk was Mobile Technology in Human Resources, and while still a new and developing area, the enormous growth and ubiquitous presence of mobile devices and increasing importance of and demand for constant connectivity in both our personal and professional lives has put planning and developing a mobile HR technology strategy high on many organizations lists of priorities in 2012. Numerous studies have shown that the confluence of ever-rising sales of smartphones and tablets; and the increasing tendency for workers of all kinds to be more mobile and less tied down to traditional, fixed-location workplaces and what now seem like old-fashioned PC-centric and traditional computing environments are driving Human Resources leaders to think about how, where, when, and for whom that the deployment of mobile HR solutions will help them address their business needs, and put information in the hands of those that need it, when they need it, and on their preferred devices. In the session we talked about some of the potential opportunities for mobile HR technologies, from simple workflow-based approval capability, to employee directories and robust employee profiles, to more advanced use cases like internal social networking and location-based mobile recruiting applications. And truly we are just scratching the surface of the potential and the value that all kinds of HR-related mobile technologies will help deliver to enterprises in the coming years. Additionally, it was encouraging to talk with many of the HR leaders in attendance who expressed interest in these kinds of mobile HR technology opportunities, as well as to hear how some of them are already working on developing their own mobile strategies or experimenting with mobile solutions in their workforces. It was a fantastic meeting and I’d like to express my thanks to Kim Bryant, IHRIM Atlanta/SE Board President, the other board members, and also the IHRIM Atlanta Chapter members and attendees at the event. If you are in the Atlanta area and are interested in HR and HR Technology, you can learn more about the programs and services that the Chapter has to offer at their website - http://www.ihrimatlantase.org/. And for people that are interested in what we at Oracle are working on in mobile, you can also sign up to receive the latest updates about the Oracle Fusion Applications tablet solutions, Oracle Fusion Tap, at https://fusiontap.oracle.com/.

  • getfacl command and Linux file permissions - getting 403 error when accessing Wordpress

In virsh on physicalServer1, I typed: virsh # migrate virtualmachine1 qemu+ssh://username@physicalServer2/system error: operation failed: migration to 'tcp:physicalServer2:49163' failed: migration failed Then I searched FAQ part on libvirt.org. It says: error: operation failed: migration to '...' failed: migration failed This is an error often encountered when trying to migrate with QEMU/KVM. This typically happens with plain migration, when the source VM cannot connect to the destination host. You will want to make sure your hosts are properly configured for migration (see the migration section of this FAQ) I managed to ssh physicalServer2 from a shell on virtualmachine1 so the above red part did not explain my failure. I also open ports on physicalServer2, iptables -L shows following information: Chain INPUT (policy ACCEPT) target prot opt source destination ACCEPT udp -- anywhere anywhere udp dpt:domain ACCEPT tcp -- anywhere anywhere tcp dpt:domain ACCEPT udp -- anywhere anywhere udp dpt:bootps ACCEPT tcp -- anywhere anywhere tcp dpt:bootps ACCEPT udp -- anywhere anywhere udp dpt:domain ACCEPT tcp -- anywhere anywhere tcp dpt:domain ACCEPT udp -- anywhere anywhere udp dpt:bootps ACCEPT tcp -- anywhere anywhere tcp dpt:bootps ACCEPT tcp -- anywhere anywhere state NEW tcp dpts:49152:49215 Chain FORWARD (policy ACCEPT) target prot opt source destination ACCEPT all -- anywhere 192.168.122.0/24 state RELATED,ESTABLISHED ACCEPT all -- 192.168.122.0/24 anywhere ACCEPT all -- anywhere anywhere REJECT all -- anywhere anywhere reject-with icmp-port-unreachable REJECT all -- anywhere anywhere reject-with icmp-port-unreachable ACCEPT all -- anywhere 192.168.122.0/24 state RELATED,ESTABLISHED ACCEPT all -- 192.168.122.0/24 anywhere ACCEPT all -- anywhere anywhere REJECT all -- anywhere anywhere reject-with icmp-port-unreachable REJECT all -- anywhere anywhere reject-with icmp-port-unreachable Chain OUTPUT (policy ACCEPT) target prot opt source destination The /var/log/libvirt/qemu/virtualmachine1.log on physicalServer2: 2011-05-06 13:37:30.708: starting up LC_ALL=C PATH=/usr/local/sbin:/usr/local/bin:/usr/bin:/usr/sbin:/sbin:/bin QEMU_AUDIO_DRV=none /usr/bin/kvm -S -M pc-0.14 -enable-kvm -m 2048 -smp 1,sockets=1,cores=1,threads=1 -name openjudge-test -uuid a8c704bc-a4f9-90db-3e57-40e60b00aac1 -nodefconfig -nodefaults -chardev socket,id=charmonitor,path=/var/lib/libvirt/qemu/virtualmachine1.monitor,server,nowait -mon chardev=charmonitor,id=monitor,mode=readline -rtc base=utc -boot c -drive file=/media/nfs/virtualmachine1.img,if=none,id=drive-ide0-0-0,format=raw -device ide-drive,bus=ide.0,unit=0,drive=drive-ide0-0-0,id=ide0-0-0 -drive if=none,media=cdrom,id=drive-ide0-1-0,readonly=on,format=raw -device ide-drive,bus=ide.1,unit=0,drive=drive-ide0-1-0,id=ide0-1-0 -netdev tap,fd=20,id=hostnet0 -device rtl8139,netdev=hostnet0,id=net0,mac=00:16:36:8a:22 :a0,bus=pci.0,addr=0x3 -chardev pty,id=charserial0 -device isa-serial,chardev=charserial0,id=serial0 -usb -vnc 127.0.0.1:2 -vga cirrus -incoming tcp:0.0.0.0:49163 -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x4 char device redirected to /dev/pts/0 2011-05-06 13:37:30.915: shutting down The /var/log/libvirt/qemu/virtualmachine1.log on physicalServer1 is empty.

  • Constructing radiotap header and ieee80211 header structures for packet injection

    - by hektor
    I am trying to communicate between two laptop machines using Wifi. The structure of the radiotap header and ieee80211 header I am using is: struct ieee80211_radiotap_header { unsigned char it_version; uint16_t it_len; uint32_t it_present; }; /* Structure for 80211 header */ struct ieee80211_hdr_3addr { uint16_t frame_ctl[2]; uint16_t duration_id; unsigned char addr1[ETH_ALEN]; unsigned char addr2[ETH_ALEN]; unsigned char addr3[ETH_ALEN]; uint16_t seq_ctl; }; struct packet { struct ieee80211_radiotap_header rtap_header; struct ieee80211_hdr_3addr iee802_header; unsigned char payload[30]; }; /* In main program */ struct packet mypacket; struct ieee80211_radiotap_header ratap_header; struct ieee80211_hdr_3addr iee802_header; unsigned char addr1[ETH_ALEN] = {0xFF,0xFF,0xFF,0xFF,0xFF,0xFF}; /* broadcast address */ unsigned char addr2[ETH_ALEN] = {0x28,0xcf,0xda,0xde,0xd3,0xcc}; /* mac address of network card */ unsigned char addr3[ETH_ALEN] = {0xd8,0xc7,0xc8,0xd7,0x9f,0x21}; /* mac address of access point i am trying to connect to */ /* Radio tap header data */ ratap_header.it_version = 0x00; ratap_header.it_len = 0x07; ratap_header.it_present = (1 << IEEE80211_RADIOTAP_RATE); mypacket.rtap_header = ratap_header; /* ieee80211 header data */ iee802_header.frame_ctl[0] = IEEE80211_FC0_VERSION_0 | IEEE80211_FC0_TYPE_MGT | IEEE80211_FC0_SUBTYPE_BEACON; iee802_header.frame_ctl[1] =IEEE80211_FC1_DIR_NODS; strcpy(iee802_header.addr1,addr1); strcpy(iee802_header.addr2,addr2); strcpy(iee802_header.addr3,addr3); iee802_header.seq_ctl = 0x1086; mypacket.iee802_header=iee802_header; /* Payload */ unsigned char payload[PACKET_LENGTH]="temp"; strcpy(mypacket.payload , payload); I am able to receive the packets when I test the transmission and reception on the same laptop. However I am not able to receive the packet transmitted on a different laptop. Wireshark does not show the packet as well. Can anyone point out the mistake I am making?

  • Splitting an internet connection between multiple separate subnetworks

    - by pythonian4000
    Problem I have an internet connection that I want to split between four separate networks. My requirements are: I need to be able to monitor the amount of bandwidth and data being used by each network, and notify or control as necessary. The four networks should only be able to connect to the internet, not each other. My parents need to be able to operate it, so it needs a simple, preferably Windows-based GUI. Progress so far Server I have a mini-ITX server with six Gigabit ethernet ports - one for the ethernet internet connection, one for each of the four networks, and one for remote access to the server for administration. Bandwidth control I spent a long time researching solutions here. The majority of the control systems/software I found could control bandwidth usage via QOS, but could not monitor or control the amount of data being used. Eventually I found the SoftPerfect Bandwidth Manager, which has everything I need in terms of monitoring and control - per-interface quota management, usage statistics, a web interface for checking usage, and email notifications when quotas are exceeded. It is also Windows-based and has a simple GUI. Internet sharing This is where I am having issues. I am currently using Windows XP Pro SP2 for the server (yes, I know this is far from ideal, but it's the only spare Windows OS I currently have). I can't use the built-in Internet Connection Sharing for several reasons: The upstream internet router has an IP of 192.168.0.1 which ICS clashes with, and I cannot change the router settings. ICS can only share an internet connection with a single interface, but I have four. I have tried bridging the four network cards, but then the Bandwidth Manager cannot see the four individual interfaces - it only sees the bridge. I have tried setting up Dual DHCP DNS server (and am having issues getting DHCP offers to be received by clients), but that would still require gateway software of some sort, which I have been unable to find. My current attempt is to use OpenVPN, with a server for the internet NIC and a separate client for each of the four networks. My thought is that I could bridge the OpenVPN TAP devices to each NIC, meaning that the Bandwidth Manager would control traffic from the bridge instead of the interface. I have not made much progress here though - I've never used OpenVPN before. Questions Is there a Windows software package that does everything I need? (Unlikely, I know) Is there a Windows software package that will share internet between multiple NICs without bridging? Are either of my about attempts feasible? Would it help to have a newer/server version of Windows? Is there a non-Windows alternative that is easy to use?

  • Disk IO causing high load on Xen/CentOS guest

    I'm having serious issues with a xen based server, this is on the guest partition. It's a paravirtualized CentOS 5.5.

  • OpenVPN bridged not pinging beyond openvpn server on Ubuntu/Windows 2003

  • SSH Socks Proxy wiith iptables REDIRECT

    - by Radium
    I have googled and haven`t found the answer on my question. Help me please. There are two servers: serverA with public IP 12.0.0.10 and an private IP 10.0.0.5 serverB with public IP 20.0.0.11 I have setup SOCKS proxy on serverB to serverA: ssh -D20.0.0.11:2222 [email protected] So when on my local machine in a browser i specify SOCKS proxy 20.0.0.11:2222 (serverB:2222) as external IP while browsing i get 12.0.0.10 (serverA IP). That is ok. As well if i go onto http://10.0.0.5 (serverA private IP) it is also reachable. That is what i need. I want to make servers A private IP to be available through servers B public IP on certain ports but without specifying SOCKS in my browser. I could use ssh port forward but the problem is - i need to forward many ports and do not know which exactly - i know only the range. So when i connect to 20.0.0.11 to any port , for example, from 3000:4000 range, i want that traffic to be redirected to 10.0.0.5 on the same port. That is why i`ve decided maybe SOCKS proxy via SSH and iptables REDIRECT could help me. Client - serverBPublicIP (any port from range 3000:4000) - serverAPublicIP - serverAPrivateIP (the port was requested on serverBPublicIP) On serverB i do: ssh -D20.0.0.11:2222 [email protected] iptables -t nat -A PREROUTING -d 20.0.0.11 -p tcp --dport 3000:4000 -j REDIRECT --to-port 2222 But that does not work - when i telnet on 20.0.0.11:3001 for example i do not see any proxied traffic on the serverA. What should i do else? I have tried tcpsocks like this (in example i am telneting to 20.0.0.11:3001) Client -> 20.0.0.11:3001 -> iptables REDIRECT from 3001 --to-port 1111 -> tcpsocks from 1111 to 2222 -> SOCKS proxy from serverB to serverA on port 2222 -> serverA But i do not know what to do with the traffic on serverA. How to route it to its private IP. Help me please. I know, VPN removes all the hell i am trying to create, but i have no ability to use tun/tap device. It is disabled.

  • OpenVPN multiple servers on the same subnet, high availability

    - by andre
    Hey everyone. Let me start by saying that my Linux experience isn't super awesome but I can usually find my way around things easily. Over at work we have an OpenVPN setup that's been due for some improvement for a while now. The main server (tap mode) runs in our office, behind a rather slow DSL connection. The main problem is that, since I'm usually out of the office, every time I want to access something on the virtual network I have to go through that server to get anywhere else. We have two servers up on 100 Mbit connections that we use for development and production purposes, about 3 more servers in the office (one of them behind a different T1 line for VOIP) and about two dozen clients who use the network on a daily basis from various locations. We've had situations where network routing (outside of our control) would not allow people to reach our main OpenVPN server whilst the other locations were connectable. Also any time someone outside the office wants to fetch something from any of the servers (say, a 500 MB code repository), a whopping 20 KB/s download speed is just unacceptable these days (did I mention slow DSL? ok). We had to implement traffic shaping on this server since maxing out this connection was fairly trivial. I had the thought of running two (or more) OpenVPN servers in the network. These would have to have the same subnet though, as our application relies on virtual network's IP addresses for some of its core functionality. The clients would also preferably retain the same IP addresses but that's not vital. For simplicity, lets call the current server office and the second server I'm setting up, cloud. Call the server on the T1 phone. This proved to be rather complex because as soon as I connect to cloud, I cannot see office. Any routes to a server that would go through office also do not work while I'm connected to cloud (no ping, nothing) and vice-versa. There's no rules for iptables that would be blocking the traffic either. Recently I came across this article on linuxjournal but the solution they provide seems to only cover the use of two servers and somewhat outdated (can't even find much documentation, their wiki is offline). They also state that adding more servers would be a complex task. Ideally I would like to keep the existing server office running the virtual network and also run the OpenVPN daemon on the cloud and phone servers (100 Mbit and very reliable connection, respectively) so that we're on safe ground in case of a hardware failure, DSL failure, etc. So, in essence, I'm looking for a highly available OpenVPN solution (fix, patch, hack, tweak, whatever you want to call it) that will accept connections on multiple hosts (2 or more) whilst keeping the same IP address subnet regardless of the server to which you connect to. Thanks for reading and sorry for the long post, I hope it gets the point across :P

  • Why is Windows 7 announcing itself as an IPv6 router?

    - by Paul
    I have a 6in4 ipv6 connection from a linux box to a broker. I use gogoc to establish the connection to the broker, and radvd to advertise the route to clients on the network. All this appears to work, the problem is that I have a Windows 7 machine on the same network, and it is advertising itself as a ipv6 router. Which it is not. This is output from radvdump: # # radvd configuration generated by radvdump 1.8.5 # based on Router Advertisement from [snip]:ea2 # received by interface eth0 # interface eth0 { AdvSendAdvert on; # Note: {Min,Max}RtrAdvInterval cannot be obtained with radvdump AdvManagedFlag on; AdvOtherConfigFlag on; AdvReachableTime 0; AdvRetransTimer 0; AdvCurHopLimit 0; AdvDefaultLifetime 1800; AdvHomeAgentFlag off; AdvDefaultPreference medium; AdvSourceLLAddress on; AdvLinkMTU 1500; }; # End of interface definition # # radvd configuration generated by radvdump 1.8.5 # based on Router Advertisement from [snip]:1121 # received by interface eth0 # interface eth0 { AdvSendAdvert on; # Note: {Min,Max}RtrAdvInterval cannot be obtained with radvdump AdvManagedFlag off; AdvOtherConfigFlag off; AdvReachableTime 0; AdvRetransTimer 0; AdvCurHopLimit 64; AdvDefaultLifetime 1800; AdvHomeAgentFlag off; AdvDefaultPreference medium; AdvLinkMTU 1280; AdvSourceLLAddress on; prefix [snip]::/64 { AdvValidLifetime 86400; AdvPreferredLifetime 14400; AdvOnLink on; AdvAutonomous on; AdvRouterAddr off; }; # End of prefix definition }; # End of interface definition And I end up with two routes: $ ip -6 route [snip]::/64 dev eth0 proto kernel metric 256 expires 86117sec fe80::/64 dev eth0 proto kernel metric 256 default via [snip]:ea2 dev eth0 proto kernel metric 1024 expires 1492sec default via [snip]:1121 dev eth0 proto kernel metric 1024 expires 1506sec The ea2 route is to the Windows7 box. It doesn't have a router installed, and doesn't have any tun/tap interfaces. I can't see why it is doing this. I could disable ipv6 on it, but I want it to be a client, not a router. Update: The IP Helper service (Provides tunnel connectivity using IPv6 transition technologies (6to4, ISATAP, Port Proxy, and Teredo), and IP-HTTPS. If this service is stopped, the computer will not have the enhanced connectivity benefits that these technologies offer.) seems to be the culprit, as if it is stopped, I don't get the routes advertised. So my question is now more specifically "why is IP Helper announcing routes?".
