  • Why does Chrome video performance substantially degrade after waking from suspend in 10.10?

    - by Grant Heaslip
    Note: For some more details, some of which may not be true given what I've figured out, see this post. When I first boot my computer, video performance (both native H.264 HTML5 in YouTube and Vimeo, and in Flash) in Chrome is perfectly reasonable. CPU usage stays slow, everything works correctly, and the video is silky-smooth. But for whatever reason, if I suspend my computer then wake it up, video performance plummets. Full screen HTML5 video is choppy at best, and full-screen Flash video basically brings my computer to its knees (I'm talking less than a frame a second, and a 5 second lead time to leave full-screen after hitting Esc). Restarting Chrome doesn't fix this — I need to completely restart my machine before performance goes back to normal. Video performance in other applications, such as Movie Player, doesn't seem to be affected at all by the suspend cycle — it's only Chrome. I'm using a Lenovo X201, with an Intel GMA HD graphics chipset, and Intel compnents all around (I don't need any proprietary drivers). This didn't happen in 10.04, and I haven't anything that I think would have caused this to happen. It's possible that a Chrome release could have caused this, but it seems less likely than a regression between 10.04 and 10.10. Any ideas? EDIT: In response Georg's comment, logging in and out doesn't fix it. Restarting Compiz or switching to Metacity (at least by using "compiz/metacity --replace & disown" — am I doing it right?) doesn't help (actually, it seemed to help somewhat with Flash once, but I haven't been able to reproduce this). I'm not sure about GDM — when I use "sudo restart gdm" I get kicked back to the Linux shell (?), which I have no idea how to get out of. Also, I want to make very clear that this isn't just a case of Flash sucking (it does,but that's beside the point). I"m seeing the same general problem with HTML5 videos, and Flash is performing better on my Nexus One than it does on my Core i5 laptop. There's something screwy going on with Chrome and/or 10.10.

  • Congratulations to the 2012 Oracle Spatial Award Winners!

    - by Mandy Ho
    I just returned from the 2012 Location Intelligence and Oracle Spatial User conference in Washington, DC, held by Directions Magazine. It was a great conference with presentations from across the country and globe, networking with Oracle Spatial users and meeting new customers and partners. As part of the yearly event, Oracle recognizes special customers and partners for their contributions to advancing mainstream solutions using geospatial technology. This was the 8th year that Oracle has recognized innovative, industry leaders.   The awards were given in three categories: Education/Research, Innovator and Partnership. Here's a little on each of the award winners. Education and Research Award Winner: Technical University of Berlin The Institute for Geodesy and Geoinformation Science of the Technical University of Berlin (TU Berlin) was selected for its leading research work in mapping of urban and regional space onto virtual 3D-city and landscape models, and use of Oracle Spatial, including 3D Vector and Georaster type support, as the data management platform. Innovator Award Winner:  Istanbul Metropolitan Municipality Istanbul is the 3rd largest metropolitan area in Europe. One of their greatest challenges is organizing efficient public transportation for citizens and visitors. There are 15 types of transportations organized by 8 different agencies. To solve this problem, the Directorate of GIS of Istanbul Metropolitan Municipality has created a multi-model itinerary system to help citizens in their decision process for using public transport or their private cars. They choose to use Oracle Spatial Network Model as the solution in our system together with Java and SOAP web services.  Partnership Award Winners: CSoft Group and OSCARS. The Partnership award is given to the ISV or integrator who have demonstrated outstanding achievements in partnering with Oracle on the development side, in taking solutions to market.  CSoft Group- the largest Russion integrator and consultancy provider in CAD and GIS. CSoft was selected by the Oracle Spatial product development organization for the key role in delivering geospatial solutions based on Oracle Database and Fusion Middleware to the Russian market.

  • ArchBeat Link-o-Rama for December 6, 2012

    - by Bob Rhubart
    Above and Beyond with the A-Team Maybe it's the coffee… If you follow this blog you've probably noticed that I regularly feature posts from members of the Oracle Fusion Middleware Architecture team, otherwise known as the A-Team. One of those bloggers, someone identified only as "fip" who writes on the A-Team SOA blog, went above and beyond on Dec 4, publishing a total of four substantial technical posts in a single day, each one worth a look: Retrieve Performance Data from SOA Infrastructure Database Configure Oracle SOA JMSAdatper to Work with WLS JMS Topics How to Achieve OC4J RMI Load Balancing Using BPEL Performance Statistics to Diagnose Performance Bottlenecks Web Service Example - Part 3: Asynchronous | The Oracle ADF Mobile Blog Part 3 in this series from the Oracle ADF Mobile blog looks at "firing the web service asynchronously and then filling in the UI when it completes." Denis says, "This can be useful when you have data on the device in a local store and want to show that to the user while the application uses lazy loading from a web service to load more data." ADF Mobile - Implementing Reusable Mobile Architecture | Andrejus Baranovskis "Reusability was always a strong part of ADF," says Oracle ACE Director Andrejus Baranovskis. "The same high reusability level is supported now in ADF Mobile." The objective of this post is "to prove technically that [the] reusable architecture concept works for ADF Mobile." Basic is Best | Eric Stephens "The world we live in and enterprises we strive to transform with enterprise architecture are complicated organisms, much like the human body," says Oracle Enterprise Architect Eric Stephens. "But sometimes a simple solution is the best approach...Whatever level of abstraction you are working at, less is more." Selling Federal Enterprise Architecture | Ted McLaughlan "EA must be 'sold' directly to the communities that matter from a coordinated, proactive messaging perspective that takes BOTH the Program-level value drivers AND the broader Agency mission and IT maturity context into consideration, " explains Ted McLaughlan. And that's true for any organization. Avoiding the "I'm Spartacus" Scenario in SOA | Ben Wilcock "This ‘SOA Spartacus’ scenario usually occurs quite soon after SOA is articulated as the primary strategic direction of the programme," says Ben Wilcock, "but before the organisation’s SOA capability is mature enough to understand what is meant by SOA, and how it should be designed and delivered." In such cases, perhaps the "A" in SOA is missing, no? Thought for the Day "It makes me feel guilty that anybody should have such a good time doing what they are supposed to do." — Charles Eames (1907–1978) Source: SoftwareQuotes.com

  • Can't fix broken packages

    - by AWE
    I am too dumb but determined to use Ubuntu that I paid a professional to install it for me (dualboot 11.10 with Win7). When I came home I got a lot of things from the software center. Skype did not have a download button so I googled it and Ubuntu help told me to do this: sudo add-apt-repository "deb http://archive.canonical.com/ $(lsb_release -sc) partner" and then this: sudo apt-get update && sudo apt-get install skype The terminal told me "that this is potentially harmful..." but I thought it was Ubuntu language meaning "are you sure?" Now the computer is mute. Items cannot be installed or removed until the package catalog is repaired, so I want to repair it but the package operation fails. "sudo aptitude -f install" - command not found Synaptic package manager tells me that I have two broken packages, libc6 and libc6-dev so I do this: sudo apt-get update && sudo apt-get upgrade which tells me to do this: sudo apt-get -f install that ends up like this: Can't exec "locale": No such file or directory at /usr/share/perl5/Debconf/Encoding.pm line 16. Use of uninitialized value $Debconf::Encoding::charmap in scalar chomp at /usr/share/perl5/Debconf/Encoding.pm line 17.

  • Instructions on how to configure a WebLogic Cluster and use it with Oracle Http Server

    - by Laurent Goldsztejn
    On October 17th I delivered a webcast on WebLogic Clustering that included a demo with Apache as the proxy server.  I realized that many steps are needed to set up the configuration I used during the demo.  The purpose of this article is to go through these steps to show how quickly and easily one can define a new cluster and then proxy requests via an Oracle Http Server (OHS). The domain configuration wizard offers the option to create a cluster.  The administration console or WLST, the Weblogic scripting tool can also be used to define a new cluster.  It can be created at any time but the servers that will participate in it cannot be in a running state. Cluster Creation using the configuration wizard Network and architecture requirements need to be considered while choosing between unicast and multicast. Multicast Vs. Unicast with WebLogic Clustering is of great help to make the best decision between the two messaging modes.  In addition, Configure Cluster offers details on each single field displayed above. After this initial configuration page, individual servers could be assigned to this newly created cluster although servers can be added later to the cluster.  What is not recommended is for the Admin server to participate in a cluster as the main purpose of the Admin server is to perform the bulk of the processing for the domain.  Servers need to stop before being assigned to a cluster.  There is also no minimum number of servers that have to participate in the cluster. At this point the configuration should be done and the cluster created successfully.  This can easily be verified from the console. Each clustered managed server can be launched to join the cluster.   At startup the following messages should be logged for each clustered managed server: <Notice> <WeblogicServer> <BEA-000365> <Server state changed to STARTING> <Notice> <Cluster> <BEA-000197> <Listening for announcements from cluster using messaging_mode cluster messaging> <Notice> <Cluster> <BEA-000133> <Waiting to synchronize with other running members of cluster_name>  It's time to try sending requests to the cluster and we will do this with the help of Oracle Http Server to play the role of a proxy server to demonstrate load balancing.  Proxy Server configuration  The first step is to download Weblogic Server Web Server Plugin that will enhance the web server by handling requests aimed at being sent to the Weblogic cluster.  For our test Oracle Http Server (OHS) will be used.  However plug-ins are also available for Apache Http server, Microsoft Internet Information Server (IIS), Oracle iPlanet Webserver or even WebLogic Server with the HttpClusterServlet. Once OHS is installed on the system, the configuration file, mod_wl_ohs.conf, will need to be altered to include Weblogic proxy specifics. First of all, add the following directive to instruct Apache to load the Weblogic shared object module extracted from the plugins file just downloaded. LoadModule weblogic_module modules/mod_wl_ohs.so and then create an IfModule directive to encapsulate the following location block so that proxy will be enabled by path (each request including /wls will be directed directly to the WebLogic Cluster).  You could also proxy requests by MIME type using MatchExpression in the Location block. <IfModule weblogic_module> <Location /wls>    SetHandler weblogic-handler    PathTrim /wls    WebLogicCluster MS1_URL:port,MS2_URL:port    Debug ON    WLLogFile        c:/tmp/global_proxy.log     WLTempDir        "c:/myTemp"    DebugConfigInfo  On </Location> </IfModule> SetHandler specifies the handler for the plug-in module  PathTrim will instruct the plug-in to trim /w ls from the URL before forwarding the request to the cluster. The list of WebLogic Servers defined in WeblogicCluster could contain a mixed set of clustered and single servers.  However, the dynamic list returned for this parameter will only contain valid clustered servers and may contain more servers if not all clustered servers are listed in WeblogicCluster. Testing proxy and load balancing It's time to start OHS web server which should at this point be configured correctly to proxy requests to the clustered servers.  By default round-robin is the load balancing strategy set by WebLogic. Testing the load balancing can be easily done by disabling cookies on your browser given that a request containing a cookie attempts to connect to the primary server. If that attempt fails, the plug-in attempts to make a connection to the next available server in the list in a round-robin fashion.  With cookies enabled, you could use two different browsers to test the load balancing with a JSP page that contains the following: <%@ page contentType="text/html; charset=iso-8859-1" language="java"  %>  <%  String path = request.getContextPath();   String getProtocol=request.getScheme();   String getDomain=request.getServerName();   String getPort=Integer.toString(request.getLocalPort());   String getPath = getProtocol+"://"+getDomain+":"+getPort+path+"/"; %> <html> <body> Receiving Server <%=getPath%> </body> </html>  Assuming that you name the JSP page Test.jsp and the webapp that contains it TestApp, your browsers should open the following URL: http://localhost/wls/TestApp/Test.jsp  Each browser should connect to a different clustered server and this simple JSP should confirm that.  The webapp that contains the JSP needs to be deployed to the cluster. You can also verify that the load is correctly balanced by looking at the proxy log file.  Each request generates a set of log entries that starts with : timestamp ================New Request: Each request is associated with a primary server and a secondary server if one is available.  For our test request, the following entries should appear in the log as well:Using Uri /wls/TestApp/Test.jsp After trimming path: '/TestApp/Test.jsp' The final request string is '/TestApp/Test.jsp' If an exception occurs, it should also be logged in the proxy log file with the prefix:timestamp *******Exception type   WeblogicBridgeConfig DebugConfigInfo enables runtime statistics and the production of configuration information.  For security purposes, this parameter should be turned off in production. http://webserver_host:port/path/xyz.jsp?__WebLogicBridgeConfig will display a proxy bridge page detailing the plugin configuration followed by runtime statistics which could help in diagnosing issues along with the analyzing of the proxy log file.  In our example the url would be: http://localhost/wls/TestApp/Test.jsp?__WebLogicBridgeConfig  Here is how the top section of the screen can look like: The bottom part of the page contains runtime statistics, here is a snippet of it (unrelated with the previous JSP example).   This entire plugin configuration should be very similar with other web servers, what varies is the name of the proxy server configuration file. So, as you can see, it only takes a few minutes to configure a Weblogic cluster and get servers to join it.
