  • Load balancing on Ubuntu Server

    - by SabreWolfy
    I have Ubuntu 10.04.4 server (32-bit) installed on a headless quad-core machine with 2GB RAM. I'm running a command-line analysis which is analyzing a large amount of data, but which does not require a large amount of RAM. The tool does not provide any multi-threading, so the CPU load is sitting at 1.00 (or sometimes just a little over). I ran top and pressed 1 to see the load on each of the cores and noticed that "Cpu1" is always running at 100%. I thought that the load would be distributed between the cores, rather than loading one core all the time. I'm sure I've seen this load-balancing behaviour before in Ubuntu or Debian Desktop versions. Why would the Server edition work differently? The analysis will likely take several hours to run, so loading one core at 100% for many hours while the other 3 remain idle is surely not the best approach?

  • Using EUSM to manage EUS mappings in OUD

    - by Sylvain Duloutre
    EUSM is a command line tool that can be used to manage the EUS settings starting with the 11.1 release of Oracle. In the 11.1 release the tool is not yet documented in the Oracle EUS documentation, but this is planned for a coming release. The same commands used by EUSM can be performed from the Database Console GUI or from Grid Control*. For more details, search for the document ID 1085065.1 on OTN. The examples below don't include all the EUSM options, only the options that are used by EUS. EUSM is user friendly and intuitive. Typing eusm help <option> lists the parameters to be used for any of the available options. Here are the options related to connectivity with OUD : ldap_host="gnb.fr.oracle.com" - name of the OUD server. ldap_port=1389 - nonSSL (SASL) port used for OUD connections.  ldap_user_dn="cn=directory manager" - OUD administrator nameldap_user_password="welcome1" - OUD administrator password Find below common commands: To List Enterprise roles in OUD eusm listEnterpriseRoles domain_name=<Domain> realm_dn=<realm> ldap_host=<hostname> ldap_port=<port> ldap_user_dn=<oud administrator> ldap_user_password=<oud admin password> To List Mappings eusm listMappings domain_name=<Domain> realm_dn=<realm> ldap_host=<hostname> ldap_port=<port> ldap_user_dn=<oud admin> ldap_user_password=<oud admin password> To List Enterprise Role Info eusm listEnterpriseRoleInfo enterprise_role=<rdn of enterprise role> domain_name=<Domain> realm_dn=<realm> ldap_host=<hostname> ldap_port=<port> ldap_user_dn="<oud admin>" ldap_user_password=<oud admin password> To Create Enterprise Role eusm createRole enterprise_role=<rdn of the enterprise role> domain_name=<Domain> realm_dn=<realm> ldap_host=<hostname> ldap_port=<port> ldap_user_dn="<oud admin>" ldap_user_password=<oud admin password> To Create User-Schema Mapping eusm createMapping database_name=<SID of target database> realm_dn="<realm>" map_type=<ENTRY/SUBTREE> map_dn="<dn of enterprise user>" schema="<name of the shared schema>" ldap_host=<oud hostname> ldap_port=<port> ldap_user_dn="<oud admin>" ldap_user_password="<oud admin password>" To Create Proxy Permission eusm createProxyPerm proxy_permission=<Name of the proxypermission> domain_name=<Domain> realm_dn="<realm>" ldap_host=<hostname> ldap_port=<port> ldap_user_dn="<oud admin>" ldap_user_password=<oud admin password> To Grant Proxy permission to Proxy group eusm grantProxyPerm proxy_permission=<Name of the proxy permission> domain_name=<Domain> realm_dn="<realm>" ldap_host=<hostname> ldap_port=<port> ldap_user_dn="<oud admin>" ldap_user_password=<password> group_dn="<dn of the enterprise group>" To Map proxy permission to proxy user in DB eusm addTargetUser proxy_permission=<Name of the proxy permission> domain_name=<Domain> realm_dn="<realm>" ldap_host=<hostname> ldap_port=<port> ldap_user_dn="<oud admin>" ldap_user_password=<oud admin password> database_name=<SID of the target database> target_user=<target database user> dbuser=<Database user with DBA privileges> dbuser_password=<database user password> dbconnect_string=<database_host>:<port>:<DBSID> Enterprise role to Global role mapping eusm addGlobalRole enterprise_role=<rdn of the enterprise role> domain_name=<Domain> realm_dn="<realm>" database_name=<SID of the target database> global_role=<name of the global role defined in the target database> dbuser=<database user> dbuser_password=<database user password> dbconnect_string=<database_host>:<port>:<DBSID> ldap_host=<oid_hostname> ldap_port=<port> ldap_user_dn="<oud admin>" ldap_user_password=<oud admin password>

  • No internet access since 12.04

    - by Roelof
    I have updated yesterday to Ubuntu 12.04 but can not access the Internet. It is an old PC without wireless. But the older Ubuntu I had installed up until now (11.??) worked perfectly. I'm not that familiar with Ubuntu, and I have been trying Google for some time know, but I cannot find the answer. I noticed that running nm-tool resulted in some things that don't sound right: Type: wired Driver: ne2k-pci state: unavailable Default: no Carrier: off Does anyone have a way to fix the connection?

  • Seeking questions about creating Microsoft Live Labs Pivot collections

    - by John Conwell
    I've spent the past 3 weeks working a lot with Pivot from Microsoft Live Labs (http://getpivot.com/).  Pivot is a tool that allows you to visually explore data. Its an interesting take on visual data mining. Anyway, I've been writing a lot of code that creates a hierarchy of Pivot collections, where one item in the collection drills down into an entirly new collection. The dev community around Pivot is still very young, so there isnt much tribal knowledge built up yet.  I've spent a lot of time trying to get things to work through trial and error, as well as digging around in Reflector.  But I've finally got a framework built for programatically creating DeepZoom images, Pivot collections, Sparse Images, etc.   If anyone has any questions, or suggestions on a post topic, leave a comment and I'll try and answer your question.

  • The Enterprise Architect (EA) diary - day 22 (from business processes to implemented applications)

  • Best gui toolkit to use for creating 3D board game

    - by UserInteractive
    I have created a board game using Java and Swing - using GridLayout and various other apis. It works properly but the UI looks very very simple. I would want couple of animations like tilting the GridLayoutat any angle. There are pawns on boxes of the GridLayout that I want to be animated when somebody clicks on it. I'm not sure of the right GUI toolkit to use for this. Swing repaint is possible to a limit and cannot be used for a lot of animation and graphics. And I realized after creating the game that Swing is probably not a good tool to create games. Could anybody suggest a better framework to use that I can use it in Eclipse with Java? I was thinking of JavaFX or tools like Adobe Flash or Adobe Air. Any suggestions please?

  • How can I give my client "full access" to their PHP application's MySQL database?

    - by Micah Delane Bolen
    I am building a PHP application for a client and I'm seriously considering WordPress or a simple framework that will allow me to quickly build out features like forums, etc. However, the client is adamant about having "full access" to the database and the ability to "mine the data." Unfortunately, I'm almost certain they will be disappointed when they realize they won't be able to easily glean meaningful insight by looking at serialized fields in wp_usermeta, etc. One thought I had was to replicate a variation on the live database where I flatten out all of those ambiguous and/or serialized fields into something that is then parsable by a mere mortal using a tool as simple as phpMyAdmin. Unfortunately, the client is not going to settle for a simple backend dashboard where I create the custom reports for them even though I know that would be the easiest and most sane approach.

  • Visual Studio 2010 Zooming Keyboard Commands, Global Zoom

    One of my favorite features in Visual Studio 2010 is zoom. It first caught my attention as a useful tool for screencasts and presentations, but after getting used to it Im finding that its really useful when Im developing letting me zoom out to see the big picture, then zoom in to concentrate on a few lines of code. Zooming without the scroll wheel The common way youll see this feature demonstrated is with the mouse wheel you hold down the control key and scroll up or down to change font size....Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • Edit 100MB+ file

    - by Majid Fouladpour
    I have captured some traffic with Wireshark and saved the result as a file. The file has 3 sections now: request headers response headers response body The response body is to become an flv file, but now everything is saved as a single file. So I need a way to delete the first two sections from the file, but the problem is that the file is very big (over a thousand mega bytes). I have tried to open it with gedit, but no matter how long I wait, gedit hangs and remains unresponsive until I kill it. What tool can I use to edit this big file easily?

  • Pendrive USB Ubuntu installation - black screen on boot

    - by ubuntico
    I see many posts on this, but no solution. I installed Ubuntu 12.04 on my 16GB USB flash drive using this official link using their tool Universal USB Installer. Installation to USB went fine so I set my laptop to boot from USB and the Ubuntu was recognized. I saw the usual boot screen and I chose option "Run Ubuntu from this USB". The boot process started and after 5-6 seconds the screen goes black and non-responsive. I thought that it hang on X loading so I tried switching to console via Ctrl+Alt+F1-6 but the system did not respond. Why is this happening? Am I doing something wrong? PS. My laptop is HP Pavillion G6

  • Is Ubuntu MAAS free? Will it remain like that?

    - by Bruno Pereira
    Ubuntu MAAS, very cool, awesome in fact, looks like a unique tool for several jobs. It looks free, but part of its documentation starts already with clauses that would scare anyone with interest in it: Documentation is copy righted by Canonical; Documentation must be used only for non-commercial purposes; If documentation is distributed within the non-commercial clause you must retain copyright; It just sounds a lot for a guide on how to install MAAS + Juju + Openstack and that scares me a bit. Under what license is Ubuntu MAAS distributed and what would be the reasoning for being so worried about copyrighting a guide like that so heavily? Is Ubuntu MAAS free? Will it continue like that?

  • How to determine the version and origin of proprietary drivers installed by Additional Drivers?

    - by Bribles
    How can I tell which version and from which repository the Additional Drivers tool is trying to install the fglrx graphics driver? It says that I have a different version of the driver in use. I installed the driver from maverick/restricted and apt-cache tells me it's from a regular Ubuntu mirror. The installed version is the same as the candidate version. Can I get Additional Drivers to tell me what it would install if I activated the driver through it? Is it possible Additional Drivers just assumes it's a different version since it was installed by a different process?

  • What file manager/uploader do you use with your embeded wysiwyg editor ?

    - by Wookai
    I am looking for a wysiwyg editor to allow user to edit part of their website. I already worked with TinyMCE, and heard about CKEditor, which both look great. However, they both lack a free (PHP) file manager/uploader, as they sell their own tool to make some money. I found a few free alternatives for TinyMCE, the best one (for my needs) being PHP Letter's one, but I was wondering about what the community uses ? Do you buy the "official" file manager ? Do you code your own ? Or do you have a great (free) alternative ?

  • quick prototyping in project design & development

    - by lurscher
    i'm currently working on a project in my spare time (mostly 3-4 hours from monday to friday, and up to 6 hours on sundays) and i've found redmine very useful to hold a record of development tasks. However, there are some stuff, specially when you are trying to prototype or brainstorm a redesign of a set of related classes, that the best tool that i've found for this still is a sheet of paper and a pen. I want to understand if maybe i'm just short of getting to work properly with existing tools. Do you find the use of a notebook or a journal an unavoidable part of software design? are there better alternatives? how do you organize pen-and-paper work and other software management tools like redmine?

  • How do you deal with web designers who are too afraid to read and touch PHP code?

    - by Lacrymology
    I've been hired to make a website and am working with a designer (who happens to be the guy who is in contact with the client and hired me, so no, I can't kick his ass out =) ) who's too afraid to touch into the php code, and is too newbie in html and css to give me good enough models, so the work of today will be going through his new html model of a half-programmed page and removing s and changing classes and the such. Is there some kind of tool, or some better workflow in order to make this easier for both of us? maybe I'm dealing with this the wrong way altogether, I'm new to web development, and I don't know enough html/css (and he supposedly does) to have him just give me a graphic mock-up and do the whole thing, so what we're doing is he gives me a static html page that looks like he wants, and I put around it =) can anyone give me some advice on this?

  • Moving Ubuntu to a new hdd

    - by jaurisan
    I have a 300gb hdd which I am currently using on my older PC. Now I want to have a copy of those 300GB into a new 1TB hdd (installed in a new computer). My "problem" is that the 1TB hdd already has a 50GB partition with a Win XP (the rest of the space is not partitioned). The 300GB disk has a 240GB partition for Ubuntu, and the rest is a FAT partition which I don't care if it gets copied or not to the new disk. So how can I transfer the entire Ubuntu to the new hard disk and still being able to boot the XP? Is there a way or tool that can help me do over LAN? So I wont have to take out the hdd from the new pc and put it in the older to do the copy.
