  • Oracle WebCenter at the Enterprise 2.0 Conference

    - by Brian Dirking
    We had a great week at the E20 Conference, presenting in four sessions – Andy MacMillan gave a session titled Today’s Successful Enterprises are Social Enterprises and was on a panel that Tony Byrne moderated; Christian Finn spoke on a panel on Unified Communications Unified Communications + Social Computing = Best of Both Worlds?, Mark Bennett spoke on a panel on The Evolution of Talent Management. The key areas of focus this year were sentiment analysis, adoption and community building, the benefits of failure, and social’s role in process applications. Sentiment analysis. This was focused not on external audiences but more on employee sentiment. Tim Young showed his internal "NikoNiko" project, where employees use smilies to report their current mood. The result was a dashboard that showed the company mood by department. Since the goal is to improve productivity, people can see which departments are running into issues and try and address them. A company might otherwise wait until the end of the quarter financials to find out that there was a problem and product didn’t ship. This is a way to identify issues immediately. Tim is great – he had the crowd laughing as soon as he hit the stage, with his proposed hastag for his session: by making it 138 characters long, people couldn’t say much behind his back. And as I tweeted during his session, I loved his comment that complexity diffuses energy - it sounds like something Sun Tzu would say. Another example of employee sentiment analysis was CubeVibe. Founder and CEO Aaron Aycock, in his 3 minute pitch or die session talked about how engaged employees perform better. It was too bad he got gonged, he was just picking up speed, but CubeVibe did win the vote – congratulations to them. Internal adoption, community building, and involvement. On this topic I spoke to Terri Griffith, and she said there is some good work going on at University of Indiana regarding this, and hinted that she might be blogging about it in the near future. This area holds lots of interest for me. Amongst our customers, - CPAC stands out as an organization that has successfully built a community. So, I wonder - what are the building blocks? A strong leader? A common or unifying purpose? A certain level of engagement? I imagine someone has created an equation that says “for a community to grow at 30% per month, there must be an engagement level x to the square root of y, where x equals current community size, and y equals the expected growth rate, and the result is how many engagements the average user must contribute to maintain that growth.” Does anyone have a framework like that? The net result of everyone’s experience is that there is nothing to do but start early and fail often. Kevin Jones made this the focus of his keynote. He talked about the types of failure and what they mean. And he showed his famous kids at work video: Kevin’s blog also has this post: Social Business Failure #8: Workflow Integration. This is something that we’ve been working on at Oracle. Since so much of business is based in enterprise applications such as ERP and CRM (and since Oracle offers e-Business Suite, Siebel, PeopleSoft, and JD Edwards, as well as Fusion Applications), it makes sense that the social capabilities of Oracle WebCenter is built right into these applications. There are two types of social collaboration – ad-hoc, and exception handling. When you are in a business process and encounter an exception, you immediately look for 1) the document that tells you how to handle it, or 2) the person who can tell you how to handle it. With WebCenter built into these processes, people either search their content management system, or engage in expertise location and conversation. The great thing is, THEY DON’T HAVE TO LEAVE THE APPLICATION TO DO IT. Oracle has built the social capabilities right into the applications and business processes. I don’t think enough folks were able to see that at the event, but I expect that over the next six months folks will become very aware of it. WebCenter also provides the ability to have ad-hoc collaboration, search, and expertise location that folks need when they are innovating or collaborating. We demonstrated Oracle Social Network. It’s built on our Oracle WebCenter product to provide social collaboration inside and outside of your company. When we showed it to people, there were a number of areas that they commented on that were different from the other products being shown at the conference: Screenshots from within the product Many authors working on documents simultaneously Flagging people for follow up Direct ability to call out to people Ability to see presence not just if someone is online, but which conversation they are actively in Great stuff, the conference was full of smart people that that we enjoy spending time with. We’ll keep up in the meantime, but we look forward to seeing you in Boston.

  • How do I set a static DNS nameserver address on Ubuntu Server?

    - by Aleks
    I am trying statically to set DNS server addresses in my Ubuntu server running as virtual machine. I followed all recommendations on official Ubuntu support pages but I simply cannot get rid of my ISP's DNS servers set by DHCP. I assigned br0 interface on my host machine static IP address and eth0 on VM to use Google DNS and my own local DNS running on the second vm by setting it in /etc/network/interfaces. Tried to fiddle with head base and tail files in /etc/resolvconf/resolv.conf.d/ and tried to shuffle interface-order in /etc/resolvconf/interface-order but when I restarted network service I got the ISP's DNS addresses back every time. Is there a way that I can disable resolvconf and set up my resolv.conf file manually as I always did on Red Hat? Or at can you tell me which hook script keeps putting ISP DNSs in resolv.conf? My ISP don't allow me to change DHCP settings on my router so I cannot do it that way. Why is such a simple thing such as setting DNS servers got so complicated???

  • Discovering Assets on Multiple Subnets

    - by Owen Allen
    I saw this question recently, about making discovery work: "I am attempting to discover a group of ILOMs which seem to be on a different subnet than their hosts. When I try to discover the ILOMs, Ops Center can't find them. Is it a requirement that the ILOM and its host should be on the same subnet?" The short answer is no, related assets don't have to be on the same subnet for you to discover them. The correlation between related assets doesn't depend on them being on the same subnet. What's likely going on, if you're running into similar issues, is that the subnet where you're trying to discover systems needs to be associated with a Proxy Controller that can reach it. You can go here to see how to associate a network with a Proxy Controller. Once the network is associated with a Proxy Controller, you should be able to discover and manage assets on it.

  • SPARC T5-4 LDoms for RAC and WebLogic Clusters

    - by Jeff Taylor-Oracle
    I wanted to use two Oracle SPARC T5-4 servers to simultaneously host both Oracle RAC and a WebLogic Server Cluster. I chose to use Oracle VM Server for SPARC to create a cluster like this: There are plenty of trade offs and decisions that need to be made, for example: Rather than configuring the system by hand, you might want to use an Oracle SuperCluster T5-8 My configuration is similar to jsavit's: Availability Best Practices - Example configuring a T5-8 but I chose to ignore some of the advice. Maybe I should have included an  alternate service domain, but I decided that I already had enough redundancy Both Oracle SPARC T5-4 servers were to be configured like this: Cntl 0.25  4  64GB

  • How to share internet over VPN and inside a virtual machine (Windows)?

    - by mountrix
    ` My final goal is to have a virtual machine at work in which anything that happen inside (tcp, udp, ping, ...) will use the Internet connection of a computer at home. So, if inside this VM should I open an Internet browser to a site such as "show my IP", my home IP should be printed. I am also looking for a way to debug/develop a software inside this VM, but I would like to tunnel only the connections of this software, not the full graphical interface, this is why a Remote Desktop solution won't fit me. The connection between the both computer should be secured somehow, like in a SSH tunnel. This ultimately should allow me to have a portable VM in which I can connect to whatever networks I have access at home, in a secure way. This is my configuration: At work, I have a LAN-connected desktop computer, with Windows 7 Professional Edition as a host [computer W] On this same computer, I have a Virtual Box machine running Windows XP [computer V] At home, I have a laptop computer, running Windows 7 Home Edition [computer H] This laptop is connected to a Livebox 2 broadband modem by Wifi. What I am trying to do is to sit at work in front of the virtual machine [V], and connect to a webpage as if the request was issued from the laptop [H] at home, and the data should be securely tunneled between the both. But if I am using internet directly inside [W], it should use the normal LAN interface at work. To achieve my goal, I first try using VPN, than SSH tunneling, without success. I first tried to install Teamviewer between [W] and [H]. This is working fine, I can send files, share desktop, etc. Teamviewer has a VPN mode that creates a new VPN network interface with its own IP, both on computer [W] and [H]. This allowed me to connect [H] as a network computer inside [W] and I was able to share files, but not to share Internet. At this point, I tried to use from [W] the Internet as if I was at home. I setup a route (using route add from command line in [W]) in order to instruct each packet going to a given website to pass by the new VPN interface on [W], with the hope it will be forwarded to [H], but the webpage was simply inaccessible. I then tried to setup a Windows VPN connection between [W] and [H], using the Windows 7 VPN feature. [H] was the server and [W] the client. But it failed: I got the "Unable to join a remote PC while trying to VPN" 720 Error when I was setting up the client on [W]. I think the problem is the Livebox 2 that could blocks the packets. But I am not sure of this: 1) with Teamviewer it works fine, 2) Livebox 2 has a configuration page for port mapping that gives the proper configuration to map VPN ports as an example so I guess that it should allow it, 3) I opened the ports 1723 (TCP) and 500 (UDP) according to some forums. Virtual box has a network configuration parameter in which I can use the VPN network interface created by Teamviewer as a bridged connection. This is suppose to work in the sense that all packets issued by the virtual machine [V] is supposed to go directly to [H]. But I had no internet connection inside [V]. Using the NAT mode, [V] has internet. For me this is the feature that I look for: filtering all connections from the virtual box application to the VPN network interface, and the remaining should use the normal LAN interface. Apart from the build-in feature of VBox, I even do not know if it is possible to route the packet from a given application to a given interface. Finally I tried also SSH tunneling, but this is not the solution I looked for. Using an external SSH server (Linux), I was able to create a localhost connection on [W] (or [V]), using something like 'ssh -N -D server[H]' in order to allow a web browser located in [W] to connect to any website using the SOCKS 5 proxy created locally (SOCKS is a build-in feature of SSH). But repeating the same operation on windows, using a windows SSH server inside [W] (I tried freeSSHd), it failed: SFTP worked, but not the SOCKS tunneling, it was like the browser in [H] did not find internet. Finally only Teamviewer looked able to create a VPN between [W] and [H], but I am not able to use it, as I want, I mean using the Internet connection of [H] sitting in front of [W]. I also tried to bridge the VPN interface and the wifi interface inside [H], but it blocked my laptop, and I tried also the Internet Connection Sharing, trying to share on [H] the wifi connection over the VPN interface. This fails also, but it seems because Teamviewer actually use the wifi interface to be able to provide the VPN link, so I guess I am creating a recursive loop. I do not know what to try next... Thank you for any advice!!

  • 11.10 AMD64 alternate installer has broken packages?

    - by Ibrahim
    I'm installing Ubuntu 11.10 from the alternate install ISO because I need to use LVM. Unfortunately, at some point the installer fails because it can't install libpurple0 and ubuntu-desktop because they depend on libsasl2-modules but it's not installable somehow. It also has the same error for xserver-xorg-video-all but I think I could probably live without that one. Kind of annoying that this is broken, I'm guessing maybe if I had internet it would work but right now I'm on a campus network with a captive portal so I can't actually get a network connection without using a browser to log in. Just thought someone should know or maybe I'm doing something wrong. I'm going to try installing 11.04 alternate and then upgrading I guess.

  • Printing multiple pages per sheet doesn't work

    - by Ricky Robinson
    In Ubuntu 12.04, I added a network printer which I had previously used without any problems on a different machine (with the same release of Ubuntu). Now, with the default generic driver installed, printing multiple pages per sheet from evince doesn't work properly. If I select 2 per sheet, be it long or short edge, it always prints 4. Why is this? It used to happen with non-pdf documents in the past, like from a browser. My workaround was to print to pdf file and then print the pdf itself. Now I'm clueless... Edit: the same happens with a different network printer, in which I installed the driver specific to its particular model.

  • Help making TP-Link Wireless USB Adapter TL-WN723N work consistently

    - by Savvas Katseas
    I've only recently made the jump to Ubuntu, using 11.10/64 as my only desktop OS. Everything seems to be working fine, except my USB Wireless adapter, TP-Link's TL-WN723N which is randomly connecting and disconnecting. The connection time appears to be random, too: I've experienced hours of connectivity and lots of connections/disconnections. I've tried searching for a solution, but what I find doesn't concern this specific USB adapter. I'd like some help identifying the problem... I've also recently switched to using a D-Link router as a wireless hub, which creates its own wireless/n network. Unfortunately this didn't solve my problems, as the new n network can be joined, but there's no connectivity to the internet. I know that's not much info to help others solve my problem, so please let me know of what else I can provide to make this a better question -- and possibly help others facing similar trouble. lsusb reports that I'm using Realtek Semiconductor Corp.

  • Cross-platform distributed fault-tolerant (disconnected operation/local cache) filesystem

    - by Adrian Frühwirth
    We are facing a design "challenge" where we are required to set up a storage solution with the following properties: What we need HA a scalable storage backend offline/disconnected operation on the client to account for network outages cross-platform access client-side access from certainly Windows (probably XP upwards), possibly Linux backend integrates with AD/LDAP (permission management (user/group management, ...)) should work reasonably well over slow WAN-links Another problem is that we don't really know all possible use cases here, if people need to be able to have concurrent access to shared files or if they will only be accessing their own files, so a possible solution needs to account for concurrent access and how conflict management would look in this case from a user's point of view. This two years old blog posts sums up the impression that I have been getting during the last couple of days of research, that there are lots of current übercool projects implementing (non-Windows) clustered petabyte-capable blob-storage solutions but that there is none that supports disconnected operation nicely and natively, but I am hoping that we have missed an obvious solution. What we have tried OpenAFS We figured that we want a distributed network filesystem with a local cache and tested OpenAFS (which, as the only currently "stable" DFS supporting disconnected operation, seemed the way to go) for a week but there are several problems with it: it's a real pain to set up there are no official RHEL/CentOS packages the package of the current stable version 1.6.5.1 from elrepo randomly kernel panics on fresh installs, this is an absolute no-go Windows support (including the required Kerberos packages) is mystical. The current client for the 1.6 branch does not run on Windows 8, the current client for the 1.7 does but it just randomly crashes. After that experience we didn't even bother testing on XP and Windows 7. Suffice to say, we couldn't get it working and the whole setup has been so unstable and complicated to setup that it's just not an option for production. Samba + Unison Since OpenAFS was a complete disaster and no other DFS seems to support disconnected operation we went for a simpler idea that would sync files against a Samba server using Unison. This has the following advantages: Samba integrates with ADs; it's a pain but can be done. Samba solves the problem of remotely accessing the storage from Windows but introduces another SPOF and does not address the actual storage problem. We could probably stick any clustered FS underneath Samba, but that means we need a HA Samba setup on top of that to maintain HA which probably adds a lot of additional complexity. I vaguely remember trying to implement redundancy with Samba before and I could not silently failover between servers. Even when online, you are working with local files which will result in more conflicts than would be necessary if a local cache were only touched when disconnected It's not automatic. We cannot expect users to manually sync their files using the (functional, but not-so-pretty) GTK GUI on a regular basis. I attempted to semi-automate the process using the Windows task scheduler, but you cannot really do it in a satisfactory way. On top of that, the way Unison works makes syncing against Samba a costly operation, so I am afraid that it just doesn't scale very well or even at all. Samba + "Offline Files" After that we became a little desparate and gave Windows "offline files" a chance. We figured that having something that is inbuilt into the OS would reduce administrative efforts, helps blaming someone else when it's not working properly and should just work since people have been using this for years. Right? Wrong. We really wanted it to work, but it just doesn't. 30 minutes of copying files around and unplugging network cables/disabling network interfaces left us with (silent! there is only a tiny notification in Windows explorer in the statusbar, which doesn't even open Sync Center if you click on it!) undeletable files on the server (!) and conflicts that should not even be conflicts. In the end, we had one successful sync of a tiny text file, everything else just exploded horribly. Beyond that, there are other problems: Microsoft admits that "offline files" in Windows XP cannot cope with "large files" and therefore does not cache/sync them at all which would mean those files become unavailable if the connection drop In Windows 7 the feature is only available in the Professional/Ultimate/Enterprise editions. Summary Unless there is another fault-tolerant DFS that supports Windows natively I assume that stacking a HA Samba cluster on top of something like GlusterFS/Lustre/whatnot is the only option, but I hope that I am wrong here. How do other companies allow fault-tolerant network access to redundant storage in a heterogeneous environment with Windows?

  • How do you do ASP.Net performance testing?

    - by John
    Our team is in need of a performance testing process. We use ASP.Net (both web forms and MVC) and performance testing is not currently built into our projects. We occasionally do some ad-hoc analysis, such as checking the load on the server or SQL Server Profiler, but we don't have a true beginning to end, built into the project performance testing methodology. Where is a good place to start? I'm interested in both: Process - General knowledge, including best practices. Essential list of tools. I'm aware of a few tools, such as what's built into the pricier versions of VS 2010 and JetBrains products, though I haven't used them.

  • Upgrade to Xubuntu 11.04 Breaks Wireless

    - by fleamour
    When I tried to connect at my mother's house and then my brother's house; the little connection icon would circle forever before eventually prompting for password. I have triple checked all network keys & then some. Even with my home network I now have to revert to 10.04 LTS Lucid Lynx (dual boot) or wired Ethernet. Not even sure where to start trouble shooting TBH? My card is a Edimax EW-7108PCg PCMCIA card which I bought for it's out the box Linux compatibility. Hardware is an IBM Thinkpad T21.

  • Configure Jenkins and Tomcat using Puppet on Vagrant

    - by ex3v
    I'm playing with setting up my first Spring + jenkins + Tomcat CI dev environment. For now it's just a test/fun phase, but in the near future I'll be starting new project with my coworkers. That's the reason that I want development environment virtualized and exactly te same on every development machine, as well as on production server. I choosen to use Vagrant and to try to write puppet scripts that not only install everything, but also configure everything so each of us will have the same jenkins plugins, same jenkins and tomcat login and password, and literally after calling vagrant up we are ready to work. What I managed to do so far is installation of stuff needed and port forwarding. My vagrantfile looks like this (comments stripped): VAGRANTFILE_API_VERSION = "2" Vagrant.configure(VAGRANTFILE_API_VERSION) do |config| config.vm.box = "precise32" config.vm.box_url = "http://files.vagrantup.com/precise32.box" config.vm.network :forwarded_port, guest: 80, host: 8090 config.vm.network :forwarded_port, guest: 8080, host: 8091 config.vm.network :private_network, ip: "192.168.33.10" config.vm.provision :puppet do |puppet| puppet.manifests_path = "puppet/" puppet.manifest_file = "default.pp" puppet.options = ['--verbose'] end end And this is my puppet file: Exec { path => [ "/bin/", "/sbin/" , "/usr/bin/", "/usr/sbin/" ] } class system-update { exec { 'apt-get update': command => 'apt-get update', } $sysPackages = [ "build-essential" ] package { $sysPackages: ensure => "installed", require => Exec['apt-get update'], } } class tomcat { package { "tomcat": ensure => present, require => Class["system-update"], } service { "tomcat": ensure => "running", require => Package["tomcat"], } } class jenkins { package { "jenkins": ensure => present, require => Class["system-update"], } service { "jenkins": ensure => "running", require => Package["jenkins"], } } include system-update include tomcat include jenkins Now, when I hit vagrant provision and go to http://localhost:8091/ I can see jenkins running, so above script works good. Next step is configurating jenkins and tomcat by extending above puppet scripts. I'm pretty green when it comes to CI. After wandering around web I've found few tutorials about jenkins configuration (here's one of them). I really want to move configuration presented in this tutorial to puppet file, so when I spread my vagrantfile and puppet file between my coworkers, I will be sure that everyone has exactly te same setup. Unfortunately I'm also green about using puppet, I don't know how to do this. Any help will be apreciated.

  • How to make Jetty webserver listen on port 80?

    - by Jonas
    I would like to use Jetty as a webserver. I have edited the configuration file at /etc/default/jetty and set: # change to 0 to allow Jetty start NO_START=0 # Listen to connections from this network host # Use 0.0.0.0 as host to accept all connections. JETTY_HOST=0.0.0.0 Now I can reach the Jetty webserver at http://192.168.1.10:8080 but I would like to have Jetty listening on port 80. I have tried this setting in the same configuration file: # The network port used by Jetty JETTY_PORT=80 and then restart Jetty with sudo service jetty restart but it doesn't work. How can I change so that the Jetty webserver is listening on port 80?
