  • Performance Drop Lingers after Load [closed]

    - by Charles
    Possible Duplicate: How do you do Load Testing and Capacity Planning for Databases I'm noticing a drop in performance after subsequent load tests. Although our cpu and ram numbers look fine, performance seems to degrade over time as sustained load is applied to the system. If we allow more time between the load tests, the performance gets back to about 1,000 ms, but if you apply load every 3 minutes or so, it starts to degrade to a point where it takes 12,000 ms. None of the application servers are showing lingering apache processes and the number of database connections cools down to about 3 (from a sustained 20). Is there anything else I should be looking out for here?

  • Turning a running Linux system into a KVM instance on another machine

    - by Charles
    I have two physical machines that I wish to virtualize. I can not (physically) plug the hard drives from either machine into the new machine that will act as their VM host, so I think that copying the entire structure of the system over using dd is out of the question. How can I best go about migrating these machines from their hardware to the KVM environment? I've set up empty, unformatted LVM logical volumes to host their filesystems, with the understanding that giving the VMs a real partition to work with achieves higher performance than sticking an image on the filesystem. Would I be better off creating new OS installs and rsyncing the differences over? FWIW, the two machines to be VM'd are running CentOS 5, and the host machine is running Ubuntu Server 10.04 for no particularly important reason. I doubt this matters too much, as it's still going to be KVM and libvert that matter.

  • SQL query. An unusual join. DB implemented in sqlite-3

    - by user02814
    This is essentially a question about constructing an SQL query. The db is implemented with sqlite3. I am a relatively new user of SQL. I have two tables and want to join them in an unusual way. The following is an example to explain the problem. Table 1 (t1): id year name ------------------------- 297 2010 Charles 298 2011 David 300 2010 Peter 301 2011 Richard Table 2 (t2) id year food --------------------------- 296 2009 Bananas 296 2011 Bananas 297 2009 Melon 297 2010 Coffee 297 2012 Cheese 298 2007 Sugar 298 2008 Cereal 298 2012 Chocolate 299 2000 Peas 300 2007 Barley 300 2011 Beans 300 2012 Chickpeas 301 2010 Watermelon I want to join the tables on id and year. The catch is that (1) id must match exactly, but if there is no exact match in Table 2 for the year in Table 1, then I want to choose the year that is the next (lower) available. A selection of the kind that I want to produce would give the following result id year matchyr name food ------------------------------------------------- 297 2010 2010 Charles Coffee 298 2011 2008 David Cereal 300 2010 2007 Peter Barley 301 2011 2010 Richard Watermelon To summarise, id=297 had an exact match for year=2010 given in Table 1, so the corresponding line for id=297, year=2010 is chosen from Table 2. id=298, year=2011 did not have a matching year in Table 2, so the next available year (less than 2011) is chosen. As you can see, I would also like to know what that matched year (whether exactly , or inexactly) actually was. I would very much appreciate (1) an indication (yes/no answer) of whether this is possible to do in SQL alone, or whether I need to look outside SQL, and (2) a solution, if that is not too onerous.

  • JRuby and JVM Languages at JavaOne!

    - by Yolande Poirier
    "My goal with my talks at JavaOne is to teach what is happening at the JVM level and below so people understand better where we are going" explains Charles Nutter, Jruby project lead. In this interview, Charles shared the JRuby features he presented at the JVM Language Summit. They include foreign function interface (FFI), IO layer, character transcoding, regular expressions, compilers, coroutines, and more.  At JavaOne, he will be presenting:  Going Native: Bringing FFI to the JVM The Java Native Runtime (JNR) is a high-speed foreign function interface (FFI) for calling native code from Java without ever writing a line of C. Based on the success of JNR, JDK Enhancement Proposal (JEP) 191 will bring FFI to OpenJDK as an internal API.  The Emerging Languages Bowl: The Big League Challenge In this panel discussion, these emerging languages are portrayed by their respective champions, who explain how they may help your everyday life as a Java developer. Script Bowl 2014: The Battle Rages On In this contest, languages that run on the JVM, represented by their respective language experts, battle for most popular language status by showing off their new features. Audience members will also vote on a language that should not return in 2015. Returning from 2013 are language gurus representing Clojure, Groovy, JRuby, and Scala.

  • The 2012 JAX Innovation Awards

    - by Janice J. Heiss
    A new article, now up on otn/java, titled “The 2012 JAX Innovation Awards” reports on  important Java developments celebrated by the Awards, which were announced in July of 2012. The Awards, given by S&S Media Group, aim to, "Reward those technologies, companies, organizations and individuals that make outstanding contributions to Java." The Awards fall into three categories: Most Innovative Java Technology, Most Innovative Java Company, and Top Java Ambassador. In addition, a finalist who did not win an award receives a Special Jury prize, "in acknowledgement of their unique contribution and positive impact on the Java ecosystem."The winners were: JetBrains for Most Innovative Java Company; Adam Bien as Top Java Ambassador; Restructure 101, created by Headway Software, as Most Innovative Technology; and Charles Nutter, Special Jury award. Each winner received a $2,500 prize. The five finalists in each category were invited to attend the JAX Conference in San Francisco, California. This year's winners each received a $2,500 prize. JetBrains Fellow, Ann Oreshnikova, listed her favorite JetBrains innovations: * Nullability annotations and nullability checker* CamelCase navigation and completion* Continuous Integration in grid (on multiple agents), in TeamCity* IntelliJ Platform and its language support framework* MPS language workbench* Kotlin programming languageWhen asked what currently excites him about Java, Adam Bien, winner of the Java Ambassador Award, expressed enthusiasm over the increasing interest of smaller companies and startups for Java EE. “This is a very good sign,” he said. “Only a few years ago J2EE was mostly used by larger companies -- now it becomes interesting even for one-person shows. Enterprise Java events are also extremely popular. On the Java SE side, I'm really excited about Project Nashorn.”Special Jury Prize Winner, Charles Nutter of Red Hat, remarked that, “JRuby seems to have hit a tipping point this past year, moving from ‘just another Ruby implementation’ to ‘the best Ruby implementation for X,’ where X may be performance, scaling, big data, stability, reliability, security, and a number of other features important for today's applications.

  • Lucene - querying with long strings

    - by Mikos
    I have an index, with a field "Affiliation", some example values are: "Stanford University School of Medicine, Palo Alto, CA USA", "Institute of Neurobiology, School of Medicine, Stanford University, Palo Alto, CA", "School of Medicine, Harvard University, Boston MA", "Brigham & Women's, Harvard University School of Medicine, Boston, MA" "Harvard University, Cambridge MA" and so on... (the bottom-line being the affiliations are written in multiple ways with no apparent consistency) I query the index on the affiliation field using say "School of Medicine, Stanford University, Palo Alto, CA" (with QueryParser) to find all Stanford related documents, I get a lot of false +ves, presumably because of the presence of School of Medicine etc. etc. (note: I cannot use Phrase query because of variability in the way affiliation is constructed) I have tried the following: Use a SpanNearQuery by splitting the search phrase with a whitespace (here I get no results!) Tried boosting (using ^) by splitting with the comma and boosting the last parts such as "Palo Alto CA" with a much higher boost than the initial phrases. Here I still get lots of false +ves. Any suggestions on how to approach this? If SpanNearQuery the way to go, Any ideas on why I get 0 results?

  • Attempted GCF app for Android

  • WebLogic history an interview with Laurie Pitman by Qualogy

    - by JuergenKress
    All those years that I am working with WebLogic, the BEA and Oracle era are the most well known about WebLogic evolving into a worldwide Enterprise platform for Java applications, being used by multinationals around the globe. But how did it all begin? Besides from the spare info you find on some Internet pages, I was eager to hear it in person from one of the founders of WebLogic back in 1995, before the BEA era, Laurie Pitman. Four young people, Carl Resnikoff, Paul Ambrose, Bob Pasker, and Laurie Pitman, became friends and colleagues about the time of the first release of Java in 1995. Between the four of them, they had an MA in American history, an MA in piano, an MS in library systems, a BS in chemistry, and a BS in computer science. They had come together kind of serendipitously, interested in building some web tools exclusively in Java for the emerging Internet web application market. They found many things to like about each other, some overlap in our interests, but also a lot of well-placed differences which made a partnership particularly interesting. They made it formal in January 1996 by incorporating. Read the complete article here.

  • How to read Scala code with lots of implicits?

    - by Petr Pudlák
    Consider the following code fragment (adapted from http://stackoverflow.com/a/12265946/1333025): // Using scalaz 6 import scalaz._, Scalaz._ object Example extends App { case class Container(i: Int) def compute(s: String): State[Container, Int] = state { case Container(i) => (Container(i + 1), s.toInt + i) } val d = List("1", "2", "3") type ContainerState[X] = State[Container, X] println( d.traverse[ContainerState, Int](compute) ! Container(0) ) } I understand what it does on high level. But I wanted to trace what exactly happens during the call to d.traverse at the end. Clearly, List doesn't have traverse, so it must be implicitly converted to another type that does. Even though I spent a considerable amount of time trying to find out, I wasn't very successful. First I found that there is a method in scalaz.Traversable traverse[F[_], A, B] (f: (A) => F[B], t: T[A])(implicit arg0: Applicative[F]): F[T[B]] but clearly this is not it (although it's most likely that "my" traverse is implemented using this one). After a lot of searching, I grepped scalaz source codes and I found scalaz.MA's method traverse[F[_], B] (f: (A) => F[B])(implicit a: Applicative[F], t: Traverse[M]): F[M[B]] which seems to be very close. Still I'm missing to what List is converted in my example and if it uses MA.traverse or something else. The question is: What procedure should I follow to find out what exactly is called at d.traverse? Having even such a simple code that is so hard analyze seems to me like a big problem. Am I missing something very simple? How should I proceed when I want to understand such code that uses a lot of imported implicits? Is there some way to ask the compiler what implicits it used? Or is there something like Hoogle for Scala so that I can search for a method just by its name?

    - by Edilio Rossi
    Più di 100 professsionisti -  manager della funzione Amministrazione, Finanza e Controllo in azienda e consulenti del settore - hanno partecipato al Workshop, organizzato da CUOA e Oracle Hyperion, in collaborazione con Adacta Studio Associato. E' stata un'occasione unica per approfondire i temi della pianificazione "estesa" e del controllo di gestione nelle imprese italiane - piccole, medie e grandi - alternando chiavi di lettura diverse (accademica, consulenziale, tecnologico-applicativa e utenti) ma tutte legate dal filo conduttore dell'evoluzione dei modelli, degli strumenti e dell'utilizzo dei sistemi evoluti di planning e budgeting economico-finanziario e patrimoniale. Una particolare attenzione è stata posta sul rapporto banca-impresa alla luce dell'attuale crisi e di come i sistemi innovativi di performance management e business intelligence possono aiutare il management nel ridisegno del sistema di finanziamento delle aziende e nella negoziazione con i diversi stakeholders. Grazie alle testimonianze dei casi aziendali GIV (Gruppo Italiano Vini) e Datalogic si è potuto "toccare con mano" l'utlizzo dei modelli e degli strumenti di pianificazione e controllo in realtà aziendali diverse ma che affrontano entrambe alcune delle sfide che i mercati oggi pongono alle imprese italiane.  Le presentazioni sono disponibili su richiesta inviando una mail a: paolo.leveghi-AT-oracle.com

  • Get CLSID by PIA interface Type

    - by Charles
    How can I get the CLSID for a given interface within a Primary Interop Assembly? Here's what I'm talking about: // The c# compiler does some interesting magic. // The following code ... var app = new Microsoft.Office.Interop.Outlook.Application(); // ... is compiled like so (disassembled with Reflector): var app =((Microsoft.Office.Interop.Outlook.Application) Activator.CreateInstance(Type.GetTypeFromCLSID(new Guid("0006F03A-0000-0000-C000-000000000046")))); Microsoft.Office.Interop.Outlook.Application is an interface, and therefore it cannot be instantiated directly. What's interesting here is that c# lets you treat these COM interfaces as if there where classes that you can instantiate with the new keyword. What I want to know is, given the System.Type for a given interface, how can I get the CLSID? Note: I ultimately want to be able to create an instance given the interface's System.Type - I don't really care how. I'm assuming here that the easiest way to do this would be to get CLSID given the Type, just as the c# compiler does.

  • POSIX AIO Library and Callback Handlers

    - by Charles Salvia
    According to the documentation on aio_read/write, there are basically 2 ways that the AIO library can inform your application that an async file I/O operation has completed. Either 1) you can use a signal, 2) you can use a callback function I think that callback functions are vastly preferable to signals, and would probably be much easier to integrate into higher-level multi-threaded libraries. Unfortunately, the documentation for this functionality is a mess to say the least. Some sources, such as the man page for the sigevent struct, indicate that you need to set the sigev_notify data member in the sigevent struct to SIGEV_CALLBACK and then provide a function handler. Presumably, the handler is invoked in the same thread. Other documentation indicates you need to set sigev_notify to SIGEV_THREAD, which will invoke the callback handler in a newly created thread. In any case, on my Linux system (Ubuntu with a 2.6.28 kernel) SIGEV_CALLBACK doesn't seem to be defined anywhere, but SIGEV_THREAD works as advertised. Unfortunately, creating a new thread to invoke the callback handler seems really inefficient, especially if you need to invoke many handlers. It would be better to use an existing pool of threads, similar to the way most network I/O event demultiplexers work. Some versions of UNIX, such as QNX, include a SIGEV_SIGNAL_THREAD flag, which allows you to invoke handlers using a specified existing thread, but this doesn't seem to be available on Linux, nor does it seem to even be a part of the POSIX standard. So, is it possible to use the POSIX AIO library in a way that invokes user handlers in a pre-allocated background thread/threadpool, rather than creating/destroying a new thread everytime a handler is invoked?
