  • Idea of an algorithm to detect a website's navigation structure?

    - by Uwe Keim
    Currently I am in the process of developing an importer of any existing, arbitrary (static) HTML website into the upcoming release of our CMS. While the downloading the files is solved successfully, I'm pulling my hair off when it comes to detect a site structure (pages and subpages) purely from the HTML files, without the user specifying additional hints. Basically I want to get a tree like: + Root page 1 + Child page 1 + Child page 2 + Child child page1 + Child page 3 + Root page 2 + Child page 4 + Root page 3 + ... I.e. I want to be able to detect the menu structure from the links inside the pages. This has not to be 100% accurate, but at least I want to achieve more than just a flat list. I thought of looking at multiple pages to see similar areas and identify these as menu areas and parse the links there, but after all I'm not that satisfied with this idea. My question: Can you imagine any algorithm when it comes to detecting such a structure? Update 1: What I'm looking for is not a web spider, but an algorithm do create a logical tree of the relationship of the pages to be able to create pages and subpages inside my CMS when importing them. Update 2: As of Robert's suggestion I'll solve this by starting at the root page, and then simply parse links as you go and treat every link inside a page simply as a child page. Probably I'll recurse not in a deep-first manner but rather in a breadth-first manner to get a more balanced navigation structure.

  • MVC 4 and the App_Start folder

    - by pjohnson
    I've been delving into ASP.NET MVC 4 a little since its release last month. One thing I was chomping at the bit to explore was its bundling and minification functionality, for which I'd previously used Cassette, and been fairly happy with it. MVC 4's functionality seems very similar to Cassette's; the latter's CassetteConfiguration class matches the former's BundleConfig class, specified in a new directory called App_Start.At first glance, this seems like another special ASP.NET folder, like App_Data, App_GlobalResources, App_LocalResources, and App_Browsers. But Visual Studio 2010's lack of knowledge about it (no Solution Explorer option to add the folder, nor a fancy icon for it) made me suspicious. I found the MVC 4 project template has five classes there--AuthConfig, BundleConfig, FilterConfig, RouteConfig, and WebApiConfig. Each of these is called explicitly in Global.asax's Application_Start method. Why create separate classes, each with a single static method? Maybe they anticipate a lot more code being added there for large applications, but for small ones, it seems like overkill. (And they seem hastily implemented--some declared as static and some not, in the base namespace instead of an App_Start/AppStart one.) Even for a large application I work on with a substantial amount of code in Global.asax.cs, a RouteConfig might be warranted, but the other classes would remain tiny.More importantly, it appears App_Start has no special magic like the other folders--it's just convention. I found it first described in the MVC 3 timeframe by Microsoft architect David Ebbo, for the benefit of NuGet and WebActivator; apparently some packages will add their own classes to that directory as well. One of the first appears to be Ninject, as most mentions of that folder mention it, and there's not much information elsewhere about this new folder.

  • Default Parameter in .NET 4(C#)

    - by Yousef_Jadallah
    During my using for the new release .NET 4, I notice that C# support default (Optional) Parameters, after thousands of complains form C# programmer- especially it was supported by VB.NET- now it's available. Let's create Test function with Optional Parameter   private void TestFunction(string para1, string para2 = "Default") { Response.Write("Parameter one =" + para1 +" , Parameter two="+ para2 ); } Then, if you try to call this method the Intellisense display likes this:   .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; }   Therefore,if you don’t pass the second parameter the value of para2 will be “Default”. With this new future in C#, you can ignore many overload functions event it was acceptable solution!

I am running Ubuntu 12.04.2 and have the infamous (as I see everywhere in the net) problem with Atheros AR9462 wifi card. I tried everything to fix it and compat drivers are the only solution that I haven't tried. I tried to install some random package from kernel.org site and it couldn't make the driver (it threw some error). Then I updated the kernel to 3.10-rc7 and downloaded the last release of compat drivers and again the same problem occured. I reinstalled Ubuntu 12.04.2 and now I am using the 3.5 kernel because I don't know if rc7 is stable version. So my question is which compat wireless or compat drivers to download for this kernel and what is the process of installing. I tried with some command from the repository and it returned that it's not found. PS I am new to Ubuntu and Linux in general so explaining at length the install process and which driver I should install would be appreciated.

  • The Java Specialist: An Interview with Java Champion Heinz Kabutz

    - by Janice J. Heiss
    Dr. Heinz Kabutz is well known for his Java Specialists’ Newsletter, initiated in November 2000, where he displays his acute grasp of the intricacies of the Java platform for an estimated 70,000 readers; for his work as a consultant; and for his workshops and trainings at his home on the Island of Crete where he has lived since 2006 -- where he is known to curl up on the beach with his laptop to hack away, in between dips in the Mediterranean. Kabutz was born of German parents and raised in Cape Town, South Africa, where he developed a love of programming in junior high school through his explorations on a ZX Spectrum computer. He received a B.S. from the University of Cape Town, and at 25, a Ph.D., both in computer science. He will be leading a two-hour hands-on lab session, HOL6500 – “Finding and Solving Java Deadlocks,” at this year’s JavaOne that will explore what causes deadlocks and how to solve them. Q: Tell us about your JavaOne plans.A: I am arriving on Sunday evening and have just one hands-on-lab to do on Monday morning. This is the first time that a non-Oracle team is doing a HOL at JavaOne under Oracle's stewardship and we are all a bit nervous about how it will turn out. Oracle has been immensely helpful in getting us set up. I have a great team helping me: Kirk Pepperdine, Dario Laverde, Benjamin Evans and Martijn Verburg from jClarity, Nathan Reynolds from Oracle, Henri Tremblay of OCTO Technology and Jeff Genender of Savoir Technologies. Monday will be hard work, but after that, I will hopefully get to network with fellow Java experts, attend interesting sessions and just enjoy San Francisco. Oh, and my kids have already given me a shopping list of things to get, like a GoPro Hero 2 dive housing for shooting those nice videos of Crete. (That's me at the beginning diving down.) Q: What sessions are you attending that we should know about?A: Sometimes the most unusual sessions are the best. I avoid the "big names". They often are spread too thin with all their sessions, which makes it difficult for them to deliver what I would consider deep content. I also avoid entertainers who might be good at presenting but who do not say that much.In 2010, I attended a session by Vladimir Yaroslavskiy where he talked about sorting. Although he struggled to speak English, what he had to say was spectacular. There was hardly anybody in the room, having not heard of Vladimir before. To me that was the highlight of 2010. Funnily enough, he was supposed to speak with Joshua Bloch, but if you remember, Google cancelled. If Bloch has been there, the room would have been packed to capacity.Q: Give us an update on the Java Specialists’ Newsletter.A: The Java Specialists' Newsletter continues being read by an elite audience around the world. The apostrophe in the name is significant.  It is a newsletter for Java specialists. When I started it twelve years ago, I was trying to find non-obvious things in Java to write about. Things that would be interesting to an advanced audience.As an April Fool's joke, I told my readers in Issue 44 that subscribing would remain free, but that they would have to pay US$5 to US$7 depending on their geographical location. I received quite a few angry emails from that one. I would have not earned that much from unsubscriptions. Most readers stay for a very long time.After Oracle bought Sun, the Java community held its breath for about two years whilst Oracle was figuring out what to do with Java. For a while, we were quite concerned that there was not much progress shown by Oracle. My newsletter still continued, but it was quite difficult finding new things to write about. We have probably about 70,000 readers, which is quite a small number for a Java publication. However, our readers are the top in the Java industry. So I don't mind having "only" 70000 readers, as long as they are the top 0.7%.Java concurrency is a very important topic that programmers think they should know about, but often neglect to fully understand. I continued writing about that and made some interesting discoveries. For example, in Issue 165, I showed how we can get thread starvation with the ReadWriteLock. This was a bug in Java 5, which was corrected in Java 6, but perhaps a bit too much. Whereas we could get starvation of writers in Java 5, in Java 6 we could now get starvation of readers. All of these interesting findings make their way into my courseware to help companies avoid these pitfalls.Another interesting discovery was how polymorphism works in the Server HotSpot compiler in Issue 157 and Issue 158. HotSpot can inline methods from interfaces that have only one implementation class in the JVM. When a new subclass is instantiated and called for the first time, the JVM will undo the previous optimization and re-optimize differently.Here is a little memory puzzle for your readers: public class JavaMemoryPuzzle {  private final int dataSize =      (int) (Runtime.getRuntime().maxMemory() * 0.6);  public void f() {    {      byte[] data = new byte[dataSize];    }    byte[] data2 = new byte[dataSize];  }  public static void main(String[] args) {    JavaMemoryPuzzle jmp = new JavaMemoryPuzzle();    jmp.f();  }}When you run this you will always get an OutOfMemoryError, even though the local variable data is no longer visible outside of the code block.So here comes the puzzle, that I'd like you to ponder a bit. If you very politely ask the VM to release memory, then you don't get an OutOfMemoryError: public class JavaMemoryPuzzlePolite {  private final int dataSize =      (int) (Runtime.getRuntime().maxMemory() * 0.6);  public void f() {    {      byte[] data = new byte[dataSize];    }    for(int i=0; i<10; i++) {      System.out.println("Please be so kind and release memory");    }    byte[] data2 = new byte[dataSize];  }  public static void main(String[] args) {    JavaMemoryPuzzlePolite jmp = new JavaMemoryPuzzlePolite();    jmp.f();    System.out.println("No OutOfMemoryError");  }}Why does this work? When I published this in my newsletter, I received over 400 emails from excited readers around the world, most of whom sent me the wrong explanation. After the 300th wrong answer, my replies became unfortunately a bit curt. Have a look at Issue 174 for a detailed explanation, but before you do, put on your thinking caps and try to figure it out yourself. Q: What do you think Java developers should know that they currently do not know?A: They should definitely get to know more about concurrency. It is a tough subject that most programmers try to avoid. Unfortunately we do come in contact with it. And when we do, we need to know how to protect ourselves and how to solve tricky system errors.Knowing your IDE is also useful. Most IDEs have a ton of shortcuts, which can make you a lot more productive in moving code around. Another thing that is useful is being able to read GC logs. Kirk Pepperdine has a great talk at JavaOne that I can recommend if you want to learn more. It's this: CON5405 – “Are Your Garbage Collection Logs Speaking to You?” Q: What are you looking forward to in Java 8?A: I'm quite excited about lambdas, though I must confess that I have not studied them in detail yet. Maurice Naftalin's Lambda FAQ is quite a good start to document what you can do with them. I'm looking forward to finding all the interesting bugs that we will now get due to lambdas obscuring what is really going on underneath, just like we had with generics.I am quite impressed with what the team at Oracle did with OpenJDK's performance. A lot of the benchmarks now run faster.Hopefully Java 8 will come with JSR 310, the Date and Time API. It still boggles my mind that such an important API has been left out in the cold for so long.What I am not looking forward to is losing perm space. Even though some systems run out of perm space, at least the problem is contained and they usually manage to work around it. In most cases, this is due to a memory leak in that region of memory. Once they bundle perm space with the old generation, I predict that memory leaks in perm space will be harder to find. More contracts for us, but also more pain for our customers.

  • SSMS Tools Pack 1.9.3 is out!

    - by Mladen Prajdic
    This release adds a great new feature and fixes a few bugs. The new feature called Window Content History saves the whole text in all all opened SQL windows every N minutes with the default being 30 minutes. This feature fixes the shortcoming of the Query Execution History which is saved only when the query is run. If you're working on a large script and never execute it, the existing Query Execution History wouldn't save it. By contrast the Window Content History saves everything in a .sql file so you can even open it in your SSMS. The Query Execution History and Window Content History files are correlated by the same directory and file name so when you search through the Query Execution History you get to see the whole saved Window Content History for that query. Because Window Content History saves data in simple searchable .sql files there isn't a special search editor built in. It is turned ON by default but despite the built in optimizations for space minimization, be careful to not let it fill your disk. You can see how it looks in the pictures in the feature list. The fixed bugs are: SSMS 2008 R2 slowness reported by few people. An object explorer context menu bug where it showed multiple SSMS Tools entries and showed wrong entries for a node. A datagrid bug in SQL snippets. Ability to read illegal XML characters from log files. Fixed the upper limit bug of a saved history text to 5 MB. A bug when searching through result sets prevents search. A bug with Text formatting erroring out for certain scripts. A bug with finding servers where it would return null even though servers existed. Run custom scripts objects had a bug where |SchemaName| didn't display the correct table schema for columns. This is fixed. Also |NodeName| and |ObjectName| values now show the same thing.   You can download the new version 1.9.3 here. Enjoy it!

  • Backtick (Grave accent) button sticking

    - by Scott Lemmon
    I have Ubuntu 12.04 running in a Virtual Box virtual machine, on my Windows 7 32bit system. It has been working great, except that the backtick/tilde button sticks(not physically). When I hit the backtick button it keeps repeating until another input button is pressed. So if I press the spacebar while the backtick is repeating, it stops, but if I press the shift while it is repeating, the backtick turns into a tilde, and the tilde keeps repeating until I release the shift key (at which point it's a backtick again and keeps repeating). This sticking behavior only happens with the backtick key, and only in my Ubuntu virtualization, never in windows. I've tried both my laptop's keyboard and an external USB keyboard and the problem happens on both. Both keyboards I've tried are Japanese 106/109 key layout, but I'm using them with a English(US) 101 profile. When I refer to the backtick key above, I mean where it is on the US layout. If I use the Japanese profile, the key in that location (the US backtick location) still sticks, but its no longer mapped as the backtick key. Any thoughts as to what might be causing this and possible solutions? I've searched a lot, but have not found any help so far. Any help is greatly appreciated.

  • Announcement: Oracle Database Appliance 2.4 patch update now available

    - by uwes
    The Oracle Database Appliance 2.4 patch is now available from My Oracle Support (MOS).  If you search for the Oracle Database Appliance 2.4.0.0.0 Kit under Patches it will display the newly uploaded bundles. The patch highlights include: Normal redundancy (double-mirroring) option providing 6TB of usable storage Enhanced Diagnostics - Trace File Analyzer and ODACHK Also, if you review the README, you may see content that says:        "The grid infrastructure and database patching, both are rolling upgradable. During our patching, we patch the node 1 first and when completed, we patch the node 2." I would like to clarify that the 'infrastructure' updates (OS, Firmware, ILOM, etc) will require a  short downtime of the ODA while it is applied.  When you update the grid infrastructure (--gi), the appliance manager verifies that the infrastructure was updated so you cannot just patch the GI without first updating the infrastructure. The high level update patch steps include (but not limited to): Download patch update to your ODA The --infra (infrastructure) is updated and ODA Databases are down and the ODA is/may be rebooted ODA and GI/Databases are restarted Issue the command to update the Grid Infrastructure/databases (The order of the steps are completed automatically and you cannot control when the nodes are brought up and down during the patching) Node 1 -- shutdown databases and GI Node 1 -- patch GI/database Node 1 -- bring up databases and GI Node 2 -- shutdown databases and GI Node 2 -- patch GI/database Node 2 -- bring up databases and GI A replay from Friday's with Sohan on the 2.4 release can be found here.  The PDF of the presentation is here. The Data Sheet, WP, and 2.4 Configurator are available on the ODA OTN site.

  • Kipróbálható az ingyenes új Oracle Data Miner 11gR2 grafikus workflow-val

    - by Fekete Zoltán
    Oracle Data Mining technológiai információs oldal. Oracle Data Miner 11g Release 2 - Early Adopter oldal. Megjelent, letöltheto és kipróbálható az Oracle Data Mining, az Oracle adatbányászat új grafikus felülete, az Oracle Data Miner 11gR2. Az Oracle Data Minerhez egyszeruen az SQL Developer-t kell letöltenünk, mivel az adatbányászati felület abból indítható. Az Oracle Data Mining az Oracle adatbáziskezelobe ágyazott adatbányászati motor, ami az Oracle Database Enterprise Edition opciója. Az adatbányászat az adattárházak elemzésének kifinomult eszköze és folyamata. Az Oracle Data Mining in-database-mining elonyeit felvonultatja: - nincs felesleges adatmozgatás, a teljes adatbányászati folyamatban az adatbázisban maradnak az adatok - az adatbányászati modellek is az Oracle adatbázisban vannak - az adatbányászati eredmények, cluster adatok, döntések, valószínuségek, stb. szintén az adatbázisban keletkeznek, és ott közvetlenül elemezhetoek Az új ingyenes Data Miner felület "hatalmas gazdagodáson" ment keresztül az elozo verzióhoz képest. - grafikus adatbányászati workflow szerkesztés és futtatás jelent meg! - továbbra is ingyenes - kibovült a felület - új elemzési lehetoségekkel bovült - az SQL Developer 3.0 felületrol indítható, ez megkönnyíti az adatbányászati funkciók meghívását az adatbázisból, ha épp nem a grafikus felületetet szeretnénk erre használni Az ingyenes Data Miner felület az Oracle SQL Developer kiterjesztéseként érheto el, így az elemzok közvetlenül dolgozhatnak az adatokkal az adatbázisban és a Data Miner grafikus felülettel is, építhetnek és kiértékelhetnek, futtathatnak modelleket, predikciókat tehetnek és elemezhetnek, támogatást kapva az adatbányászati módszertan megvalósítására. A korábbi Oracle Data Miner felület a Data Miner Classic néven fut és továbbra is letöltheto az OTN-rol. Az új Data Miner GUI-ból egy képernyokép: Milyen feladatokra ad megoldási lehetoséget az Oracle Data Mining: - ügyfél viselkedés megjövendölése, prediktálása - a "legjobb" ügyfelek eredményes megcélzása - ügyfél megtartás, elvándorlás kezelés (churn) - ügyfél szegmensek, klaszterek, profilok keresése és vizsgálata - anomáliák, visszaélések felderítése - stb.

  • Moving from windows to linux

    - by rincewind
    I need to reconcile these 2 facts: I don't feel comfortable working on Linux; I need to develop software for Linux. Some background: I have a 10+ years of programming experience on Windows (almost exclusively C/C++, but some .NET as well), I was a user of FreeBSD at home for about 3 years or so (then had to go back to Windows), and I've never had much luck with Linux. And now I have to develop software for Linux. I need a plan. On Windows, you can get away with just knowing a programming language, an API you're coding against, your IDE (VisualStudio) and some very basic tools for troubleshooting (Depends, ProcessExplorer, DebugView, WinDbg). Everything else comes naturally. On Linux, it's a very different story. How the hell would I know what DLL (sorry, Shared Object) would load, if I link to it from Firefox plugin? What's the Linux equivalent of inserting __asm int 3/DebugBreak() in the source and running the program, and then letting the OS call a debugger? Why the hell release builds use something, called appLoader, while debug builds work somehow different? Worst of all: how to provision Linux development environment? So, taking into account that hatred is usually associated with not knowing enough, what would you recommend? I'm ok with Emacs and GCC. I need to educate myself as a Linux admin/user, and I need to learn proper troubleshooting tools (strace is cool, btw), equivalents to the ones I mentioned above. Do I need to do Linux From Scratch? Or do I need to just read some books (I've read "UNIX programming enviornment" by Kernighan and "Advanced Programming..." by Stevens, but I need to learn something more practical)? Or do I need to have some Linux distro on my home computer?

  • Acer Aspire One 725 - missing graphic card driver?

    - by Melon
    Recently I bought an Acer Aspire One 725 Netbook and installed Ubuntu 12.10 on it. I bought it, because it can run HD movies and has Full HD on external VGA port. However, movies from youtube have a really slow framerate. If you open three tabs in Opera (for example g-mail, youtube and askubuntu) it gets really laggy. My suspicion is that the driver for graphic card is missing. When I check the System->Details->Graphics the driver is unknown. After running lspci | grep VGA I get this output: 00:01.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Device 980a From what I see, I have a AMD C70 processor integrated with (or something similar) AMD Radeon HD 6290. Has anyone had the same problem? Do you know which drivers need to be installed for the graphics to work properly? On official Acer page there are only drivers for Win7 and Win8...

  • FMw Diagnostic Framework : Automatic Capture of Diagnostic Data Upon First Failure!

    - by Daniel Mortimer
    Introduction There is nothing more frustrating than a problem that "cannot be reproduced". Logs, configuration files have been analysed but there just isn't enough information to establish the root cause. The issue maybe closed, but you are left with the feeling that the problem will raise its ugly head again in the future. Trouble is, to resolve such issues you need to capture diagnostic data at the exact time the incident occurs. Step forward Fusion Middleware Diagnostic Framework!  Diagnostic Framework monitors WebLogic Managed Servers and delivers "Automatic capture of diagnostic data upon first failure". To quote fromOracle Fusion Middleware Administrator's Guide 11g Release 1 (11.1.1)Chapter 13 Diagnosing Problems "When a critical error occurs ... the Diagnostic Framework automatically collects diagnostics, such as thread dumps, DMS metric dumps, and WebLogic Diagnostics Framework (WLDF) server image dumps ... The data is stored in a file-based repository and is accessible with command-line utilities." In other words the data collected upon first failure - especially the thread and image dumps - provides a snapshot of the system as or immediately after the problem occurs. The table below shows the type of WebLogic Server issues which fall into the scope of Diagnostic Framework How to Configure Diagnostic Framework? Depending on your Fusion Middleware product choice you may not need to do anything! Diagnostic Framework is automatically installed, configured and initiated for any WebLogic Domain which has the Oracle Java Required Files (JRF) template applied. This template is applied by default whenever you configure WebLogic Managed Servers for products such as Portal / Forms / Reports / Discoverer Identity Management ( OID , OAM , OIM etc) WebCenter SOA Check your WebLogic Domain directory structure. If you have an "adr" sub directory under DOMAIN_HOME/servers/<servername>/ then JRF template has been applied and Diagnostic Framework will be in play. Should the "adr" sub directory not exist, review the advice given in My Oracle Support article How to Apply FMW ( EM ) Control and JRF to a WebLogic Domain and Managed Servers [ID 947043.1] If you are working with a standalone WebLogic Server solution and applying Oracle JRF is not acceptable, consider using WLDF - WebLogic Diagnostic Framework. (Fusion Middleware Diagnostic Framework makes use of WLDF under the covers.) Couple of useful links about WLDF are listed below Configuring and Using the Diagnostics Framework for Oracle WebLogic Server 11g WebLogic Diagnostics Framework-A Very Useful Tool [A nice blog which describes a WLDF use case] How to Get Started With Diagnostic Framework To be frank, the Fusion Middleware Administrator's Guide is the best place to start your learning Oracle Fusion Middleware Administrator's Guide 11g Release 1 (11.1.1)Chapter 13 Diagnosing Problems A lot of reading here,  but if you are in hurry and just want to get the right information to Oracle Support to help resolve your issue, check out the next section below. How to Upload Diagnostic Framework Incident Data to Oracle Support Some Background Information There are three interfaces to the Repository: Enterprise Manager Cloud Control (Support Workbench) WLST (Command Line) ADRCI (Command Line) The Enterprise Manager Cloud Control does provide a nice GUI interface to search, view and package diagnostic framework incidents. However, this software is not to be confused with Fusion Middleware (EM) Control. Cloud Control (formerly known as Grid Control) is part of the Enterprise Manager media package. EM Cloud Control has it's own install and configuration story. Therefore, for the benefit of those yet to install and play with Cloud Control, I am going to describe how to use the command line tools. Ideally, you would only need to one command line interface, but currently I suggest using both - mainly due to the fact that ADRCI SHOW INCIDENTS does not reveal the description behind the Diagnostic Framework error code. Instructions: Note: WLST and ADRCI are case sensitive when it comes to handling parameter values. If you make a mistake, expect an unfriendly syntax error message. 1) Find the incident Note: The managed server which you are troubleshooting must be up and running. If the managed server is down, ensure the domain's Admin Server is accessible. If you cannot connect to the Admin Server or the Managed Server the example WLST commands will not work. a) Launch WLST  Note: Use the WLST which resides in the "oracle_common" directory (not WL_HOME/common/bin) otherwise you will get a syntax error like the one below Traceback (innermost last):  File "<console>", line 1, in ?NameError: listIncidents MW_HOME/oracle_common/common/bin/wlst.sh b) Connect to the managed server or the admin server e.g. wls:/offline> connect('weblogic','welcome1','t3://localhost:7020') c) Run the command wls:/MyDomain/serverConfig> listIncidents() This will list the incidents for the server to which you have connected. If you have connected to the Admin Server and want to list the incidents for a managed server within the domain, use the command wls:/MyDomain/serverConfig> listIncidents(adrHome='diag\ofm\MyDomain\MyManagedServer' ,server='MyManagedServer') Example output Incident Id     Problem Key              Incident Time         1       DFW-99998 [java.lang.NullPointerException] [oracle.error.simulator.ErrorSimulator.createNullPointerException][errorWebApp_1-0-0-0]        Fri Nov 02 10:38:46 GMT 2012  The piece highlighted in bold is the description you do not see when using the ADRCI 'SHOW INCIDENT' command. Make a note of the incident id. You are ready to move to step 2 2. Package the incident a) Set up the environment - example commands below are for Unix cd <DOMAIN_HOME>/bin . ./setDomainEnv.sh If you want ADRCI to run a Remote Diagnostic Agent collection (recommended) at generate package time, point ORACLE_HOME at oracle_common ORACLE_HOME=$MW_HOME/oracle_common; export ORACLE_HOME To prevent ADRCI from running RDA at generate package time, point ORACLE_HOME at WL_HOME/server/adr directory.  ORACLE_HOME=$WL_HOME/server/adr; export ORACLE_HOME b) Launch adrci $WL_HOME/server/adr/adrci c) Set BASE and HOMEPATH adrci> SET BASE /oracle/middleware/user_projects/domains/ mydomain/servers/mymanagedserver/adr adrci> SET HOMEPATH diag/ofm/mydomain/mymanagedserver d)  Optionally run SHOW INCIDENTS e.g. adrci> SHOW INCIDENTS -MODE DETAIL ADR Home = /oracle/middleware/user_projects/domains/mydomain/ servers/mymanagedserver/adr/diag/ofm/mydomain/mymanagedserver:***********************************************************************************************************************************INCIDENT INFO RECORD 1**********************************************************   INCIDENT_ID                   1   STATUS                        ready   CREATE_TIME                   2012-11-02 10:38:46.468000 +00:00   PROBLEM_ID                    1   CLOSE_TIME                    <NULL>   FLOOD_CONTROLLED              none   ERROR_FACILITY                DFW   ERROR_NUMBER                  99998   ERROR_ARG1                    <NULL>   ERROR_ARG2                    <NULL>   ERROR_ARG3                    <NULL>   ERROR_ARG4                    <NULL>   ERROR_ARG5                    <NULL>   ERROR_ARG6                    <NULL>   ERROR_ARG7                    <NULL>   ERROR_ARG8                    <NULL>   ERROR_ARG9                    <NULL>   ERROR_ARG10                   <NULL>   ERROR_ARG11                   <NULL>   ERROR_ARG12                   <NULL>   SIGNALLING_COMPONENT          <NULL>   SIGNALLING_SUBCOMPONENT       <NULL>   SUSPECT_COMPONENT             <NULL>   SUSPECT_SUBCOMPONENT          <NULL>   ECID                          5162744c6a2eea5e:155ff445:13ac0aae7cb:-8000-0000000000000325   IMPACTS                       01 rows fetched e)  Create a logical package IPS CREATE PACKAGE INCIDENT incident_number e.g. adrci> IPS CREATE PACKAGE INCIDENT 1Created package 1 based on incident id 1, correlation level typical f) Generate the package IPS GENERATE PACKAGE package_number IN path e.g. adrci> IPS GENERATE PACKAGE 1 IN /tmp Generated package 1 in file /tmp/DFW99998j_20121102113633_COM_1.zip, mode complete Note: If the generate package command hangs, ADRCI may be experiencing an issue when running RDA.

  • PHP 5.4 Support: Traits

    - by Ondrej Brejla
    Hi all! Today we would like to intorduce you another new PHP 5.4 feature for NetBeans 7.2 which is called Traits. Note: All PHP 5.4 features are available in your projects after setting Project Properties -> Sources -> PHP Version to PHP 5.4 value, or after choosing the same value during a PHP Project creation (in New Project Wizard). If you don't know, what Traits are, just look at the official documentation, or RFC. So what is that exact Trait support in NetBeans? Syntax is recognized correctly and code completion offers declared, inherited stuff from used traits. Note: Just one thing is not supported yet - resolving name conflicts and aliasing of method names (it means that you will not have these "virtual" names in your code completion). We would like to implement it in some next NetBeans release. Sorry for any inconvenience. That's all for today and as usual, please test it and if you find something strange, don't hesitate to file a new issue (component php, subcomponent Editor). Thanks.

  • The Hot-Add Memory Hogs

    - by Andrew Clarke
    One of the more difficult tasks, when virtualizing a server, is to determine the amount of memory that Hypervisor should assign to the virtual machine. This requires accurate monitoring and, because of the consequences of setting the value too low, there is a great temptation to err on the side of over-provisioning. This results in fewer guest VMs and, in fact, with more accurate memory provisioning, many virtual environments could support 30% more VMs. In order to achieve a better consolidation (aka VM density) ratio, Windows Server 2008 R2 SP1 has introduced what Microsoft calls ‘Dynamic Memory’. This means that the start-up RAM VM memory assigned to guest virtual machines can be allowed to vary according to demand, changing dynamically while the VM is running, based on the workload of applications running inside. If demand outstrips supply, then memory can be rationed according to the ‘memory weight’ assigned to the guest VM. By this mechanism, memory becomes a shared resource that can be reallocated automatically as demand patterns vary. Unlike VMWare’s Memory Overcommit technology, the sum of all the memory allocations to each virtual machine will not exceed the total memory of the host computer. This is fine for applications that are self-regulating in their demands for memory, releasing memory back into the 'pool' when not under peak load. Other applications however, such as SQL Server Standard and Enterprise, are by nature, memory hogs under high workload; they can grab hot-add memory whilst running under load and then never release it. This requires more careful setting-up and the SQLOS team have provided some guidelines from for configuring SQL Server in virtual environments. Whereas VMWare’s Memory Overcommit is well-proven in a number of different configurations, Hyper-V’s ‘Dynamic Memory’ is new. So far, the indications are that it will improve the business case for virtualizing and it is probably a far more intuitive technology for the average IT professional to grasp. It is certainly worth testing to see whether it works for you.

  • How do you prefer to handle image spriting in your web projects?

    - by Macy Abbey
    It seems like these days it is pretty much mandatory for web applications to sprite images if they want many images on their site AND a fast load time. (Spriting is the process of combining all images referenced from a style sheet into one/few image(s) with each reference containing a different background position.) I was wondering what method of implementing sprites you all prefer in your web applications, given that we are referring to non-dynamic images which are included/designed by the programming team and not images which are dynamically uploaded by a third party. 1. Add new images to an existing sprite by hand, create new css reference by hand. 2. Generate a sprite server-side from your css files which all reference single images set to be background images of an html element that is the same size of the image you are spriting once per build and update all css references programmatically. 3. Use a sprite generating program to generate a sprite image for you once per release and hand insert the new css class / image into your project. 4. Other methods? I prefer two as it requires very little hand-coding and image editing.

  • What are the factors affecting a new programming language?

    - by Saurav Sengupta
    I am developing a new general-purpose programming language of my own design. It's currently my own personal project. I have read of some experts saying that new languages do not usually survive (unfortunately I can't find a reference to that right now). What are the most substantial problems that a new language faces? The language syntax is similar to C/Python families, it does not use S-expressions, and it is an imperative language, but I'm doing first-class functions in it to provide the facilities of currying. In particular, I am concentrating on translating the source language to an intermediate language for execution by an interpreter, but I'm not in a position to translate to native code yet. What would be the issues with that? I've not personally used many non-native code languages, so I'm not well aware of the performance issues on today's machines. I also can't decide upon a lexer and parser generator. What would be the pros and cons of Flex and Yacc vs. hand-made? And what benefits will LLVM provide? I need to get the interpreter ready as quickly as possible. Finally, what factors will affect the language's use post release? I am planning a small library of essentials and full documentation for the first phase.

  • May In Review

    - by Richard Bingham
    Content Highlights Our Application Composer series had fresh articles on the related internal data model and lots more on Groovy, including how to manipulate your data and a useful table showing you when and where groovy scripting can be used. For those just getting started with Fusion Applications user security, this article gave some handy examples to get your going. Jani's Java Cloud Service series continued strongly, with examples of integration using ADFbc, a Web Service Proxy client, and the ADF Data Control. From Other Teams The Oracle A-Team provided a broad set of articles during May, with various topics related to Fusion Applications including patching and performance management for on-premises deployments, and generic content on both integration and data extraction via web services. As part of their presentation to Oracle Israel User Group, our AppsUX colleagues explained the fresh new type of interface to Oracle Sales, through the voice mobile apps. This was in addition to demonstrations of the newer Release 8 Simplified UI customization options. Finally Angelo, our colleague in Platform Technical Services, explained in his blog how to use the findCriteria element included in all Oracle Sales web services to reduce the data returned, making response payloads much more specific, lightweight and therefore usable. Events and Announcements Oliver explained in this post about the new set of code samples on OTN for extending Sales Cloud using Oracle Platform as a Service. In addition, a new set of cloud developer documentation was released to provide more guided-learning on extending Oracle Sales Cloud with Oracle Platform as a Service (PaaS) services. This illustrative content is mainly as downloadable PDFs, and include topics covering sales cloud extensibility basics, using web services from JDeveloper (including security), using PaaS for SaaS development, and ADF (including mobile).
