• LDoms with Solaris 11

  - by Orgad Kimchi

  Oracle VM Server for SPARC (LDoms) release 2.2 came out on May 24. You can get the software, see the release notes, reference manual, and admin guide here on the Oracle VM for SPARC page. Oracle VM Server for SPARC enables you to create multiple virtual systems on a single physical system.Each virtual system is called alogical domain and runs its own instance of Oracle Solaris 10 or Oracle Solaris 11. The version of the Oracle Solaris OS software that runs on a guest domain is independent of the Oracle Solaris OS version that runs on the primary domain. So, if you run the Oracle Solaris 10 OS in the primary domain, you can still run the Oracle Solaris 11 OS in a guest domain, and if you run the Oracle Solaris 11 OS in the primary domain, you can still run the Oracle Solaris 10 OS in a guest domain In addition to that starting with the Oracle VM Server for SPARC 2.2 release you can migrate guest domain even if source and target machines have different processor type. You can migrate guest domain from a system with UltraSPARC  T2+ or SPARC T3 CPU to a system with a SPARC T4 CPU.The guest domain on the source and target system must run Solaris 11 In order to enable cross CPU migration.In addition to that you need to change the cpu-arch property value on the source system. For more information about Oracle VM Server for SPARC (LDoms) with Solaris 11 and  Cross CPU Migration refer to the following white paper

• How do I architect 2 plugins that share a common component?

  - by James

  I have an object that takes in data and spits out a transformed output, called IBaseItem. I also have two parsers, IParserA and IParserB. These parsers transform external data (in format dataA and dataB respectively) to a format usable by my IBaseItem (baseData). I want to create 2 systems, one that works with dataA and one that works with dataB. They will allow the user to enter data and match it to the right plugins/implementations and transform the data to outData. I want to write these traffic cops myself, but have other people provide the parsers and baseitem logic, and and as such am implementing these items as plugins (hence the use of interfaces). Other programmers can choose to implement 1 or both parsers. Q: How should I structure the way base items and parsers are associated, stored, and loaded into each of my programs? Class Relations: What I've Tried: Initially I though there should be a different dll for each of my 2 traffic cops, that each have a parser and baseitem in them. However, the duplication of baseitem logic doesn't seem right (especially if the base item logic changes). I then thought the base items could all have their own dll, and then somehow associate parsers and baseitems (guids?), but I don't know if implementing the overhead id/association is adding too much complexion.

• The overlooked OUTPUT clause

  - by steveh99999

  I often find myself applying ad-hoc data updates to production systems – usually running scripts written by other people. One of my favourite features of SQL syntax is the OUTPUT clause – I find this is rarely used, and I often wonder if this is due to a lack of awareness of this feature.. The OUTPUT clause was added to SQL Server in the SQL 2005 release – so has been around for quite a while now, yet I often see scripts like this… SELECT somevalue FROM sometable WHERE keyval = XXX UPDATE sometable SET somevalue = newvalue WHERE keyval = XXX -- now check the update has worked… SELECT somevalue FROM sometable WHERE keyval = XXX This can be rewritten to achieve the same end-result using the OUTPUT clause. UPDATE sometable SET somevalue = newvalue OUTPUT deleted.somevalue AS ‘old value’,              inserted.somevalue AS ‘new value’ WHERE keyval = XXX The Update statement with output clause also requires less IO - ie I've replaced three SQL Statements with one, using only a third of the IO.  If you are not aware of the power of the output clause – I recommend you look at the output clause in books online And finally here’s an example of the output produced using the Northwind database…

• A Huge Opportunity in Small Things

  - by Tori Wieldt

  Addressing the strong demand for Java in the embedded market, Oracle is hosting a new Java Embedded @ JavaOne event in San Francisco October 3-4. The event allows decision makers to attend the Java Embedded @ JavaOne business-focused program, while their IT/development staff can attend the technically-focused JavaOne conference. [Obligatory comment about suits & ties vs. jeans & T-shirts removed.] The two-day event includes keynotes, sessions and demonstrations. In his keynote this morning, Judson Althoff, Senior Vice President of Worldwide Alliances and Channels and Embedded Sales, Oracle explained  Devices are all around us - on 24x7, connected all the time. The explosion of devices is the next IT revolution. Java is the right solution for this space. Java embedded solutions provide a framework to  provision, manage, and secure devices.  Java embedded solutions also provide the ability to aggregate, process and analyze multitude of data.  Java is one platform to program them all. Terrance Barr, Java Evangelist and Java ME expert is enthusiastic about the huge opportunity, "It's the right time and right place for Java Embedded," he said, "Oracle is looking for partners who want to take advantage of this next wave in IT." The Embedded space continues to heat up. Today, Cinterion launched the EHS5, an ultra compact, high-speed M2M communication module providing secure wireless connectivity for a wide variety of industrial applications. Last week, Oracle announced Oracle Java ME Embedded 3.2, a complete client Java runtime Optimized for resource-constrained, connected, embedded systems, Oracle Java Wireless Client 3.2, Oracle Java ME Software Development Kit (SDK) 3.2, and Oracle Java Embedded Suite 7.0 for larger embedded devices. There is a huge opportunity in small things.

• Who is a CMS really for?

  - by Eirc man

  I have started lately discovering Content Management Systems, and I was wondering, who is really CMS for? What I mean by that: is it only for companies, small businesses or individuals, that pays a contractor to make a website that it's users can just upload content through a easy interface. Or is it used also by programmers, to build their own websites, projects? Would a Facebook, Tweeter, StackExhange ever started by using a CMS, a very powerful one for example. Would you as a programmer build your own "fancy" website on top of a CMS, for example like Typo3, or you would build it from scratch? P.S To be more clear is a summary: What I mean to begin with is, would I as a developer choose a CMS to develop a website that can be scaled with a big base of users, be stuck if I choose to start with a CMS system. What if I build a website using CMS, and the website explodes in popularity, and then I wanted to add much more functionality that I have planed, is it possible that the CMS will limit the growth, because it might have not been build for that kind of scale?

• Why is purchasing Microsoft licences such a daunting task? [closed]

  - by John Nevermore

  I've spent 2 frustrating days jumping through hoops and browsing through different local e-shops for VS (Visual Studio) 2010 Pro. And WHS (Windows Home Server) FPP 2011 licenses. I found jack .. - or to be more precise, the closest I found in my country was WHS OEM 2011 licenses after multiple emails sent to individuals found on Microsoft partners page. Question being, why is it so difficult to get your hands on Microsoft licenses as an individual? Sure, you can get the latest end user operating systems from most shops, but when it comes to development tools or server software you are left dry. And companies that do sell licenses most of the time don't even put up pricing or a self service environment for buying the licenses, you need to have an hawk's eye for that shiny little Microsoft partner logo and spam through bunch of emails not knowing, if you can count on them to get the license or not. Sure, i could whip out my credit card and buy the VS 2010 license on the online Microsoft Shop. Well whippideegoddamndoo, they sell that, but they don't sell WHS 11 licenses. Why does a company make it so hard to buy their products? Let's not even talk about the licensing itself being a pain.

• Data Center Modernization: Harness the power of Oracle Exalogic and Exadata with PeopleSoft

  - by Michelle Kimihira

  Author: Latha Krishnaswamy, Senior Manager, Exalogic Product Management   Allegis Group - a Hanover, MD-based global staffing company is the largest privately held staffing company in the United States with more than 10,000 internal employees and 90,000 contract employees. Allegis Group is a $6+ billion company, offering a full range of specialized staffing and recruiting solutions to clients in a wide range of industries.   The company processes about 133,000 paychecks per week, every week of the year. With 300 offices around the world and the hefty task of managing HR and payroll, the PeopleSoft system at Allegis  is a mission-critical application. The firm is in the midst of a data center modernization initiative. Part of that project meant moving the company's PeopleSoft applications (Financials and HR Modules as well as Custom Time & Expense module) to a converged infrastructure.     The company ran a proof of concept with four different converged architectures before deciding upon Exadata and Exalogic as the platform of choice.   Performance combined with High availability for running mission-critical payroll processes drove this decision.  During the testing on Exadata and Exalogic Allegis applied a particular (11-F) tax update in production environment. What job ran for roughly six hours completed in less than 1.5 hours. With additional tuning the second run of the Tax update 11-F reduced to 33 minutes - a 90% improvement!     Not only that, the move will help the company save money on middleware by consolidating use of Oracle licensing in a single platform.   Summary With a modern data center powered by Exalogic and Exadata to run mission-critical PeopleSoft HR and Financial Applications, Allegis is positioned to manage business growth and improve employee productivity. PeopleSoft applications run on engineered systems platform minimizing hardware and software integration risks.

• C++ and system exceptions

  - by Abyx

  Why standard C++ doesn't respect system (foreign or hardware) exceptions? E.g. when null pointer dereference occurs, stack isn't unwound, destructors aren't called, and RAII doesn't work. The common advice is "to use system API". But on certain systems, specifically Win32, this doesn't work. To enable stack unwinding for this C++ code // class Foo; // void bar(const Foo&); bar(Foo(1, 2)); one should generate something like this C code Foo tempFoo; Foo_ctor(&tempFoo); __try { bar(&tempFoo); } __finally { Foo_dtor(&tempFoo); } Foo_dtor(&tempFoo); and it's impossible to implement this as C++ library. Upd: Standard doesn't forbid handling system exceptions. But it seems that popular compilers like g++ doesn't respect system exceptions on any platforms just because standard doesn't require this. The only thing that I want - is to use RAII to make code readable and program reliable. I don't want to put hand-crafted try\finally around every call to unknown code. For example in this reusable code, AbstractA::foo is such unknown code: void func(AbstractA* a, AbstractB* b) { TempFile file; a->foo(b, file); } Maybe one will pass to func such implementation of AbstractA, which every Friday will not check if b is NULL, so access violation will happen, application will terminate and temporary file will not be deleted. How many months uses will suffer because of this issue, until either author of func or author of AbstractA will do something with it? Related: Is `catch(...) { throw; }` a bad practice?

• Why is Windows registry needed?

  - by Job

  As I have debugged problems in com, side by side, dealt with dll hell, all while hating the windows registry with passion, I was wondering why is it needed. I never felt compelled to read an entire book on registry best practices, and then just "get it". I have, however, used Linux and Mac OS, and look at the ways one can install multiple versions of Python and its libraries on the same *nix computer. Because registry has somewhat of a free (albeit ugly) format, and is used for all sorts of purposes, I have never understood what essential problem it is trying to solve. For instance, Microsoft does not want you to have two different versions of MS Office installed side by side. They use registry to enforce this during installation. This limitation is artificial, in my opinion. If they really cared to allow a different behavior, they could have adjusted their architecture accordingly. In Mac OS you can install and remove apps by just dropping them into a particular folder. So, A) What essential problem it is trying to solve? B) How do other operating systems solve it?

• Flashback Database

  - by Sebastian Solbach (DBA Community)

  Flashback Database bezeichnet die Funktionalität der Oracle Datenbank, die Datenbank zeitlich auf einen bestimmten Punkt, respektive eine bestimmte System Change Number (SCN) zurücksetzen zu können - vergleichbar mit einem Rückspulknopf eines Kassettenrekorders oder der Rücksetztaste eines CD-Players. Mag dieses Vorgehen bei Produktivsystemen eher selten Einsatz finden, da beim Rücksetzten alle Daten nach dem zurückgesetzten Zeitpunkt verloren wären (es sei denn man würde dieser vorher exportieren), gibt es gerade für Test- oder Standby Systeme viele Einsatzmöglichkeiten: Rücksetzten des Systems bei fehlgeschlagenen Applikations-Upgrade Alternatives Point in Time Recovery (PITR) mit anschließendem Roll Forward (besonders geeignet bei Standby Systemen) Testdatenbank mit definiertem, reproduzierbaren Ausgangspunkt (z.B. für Real Application Testing) Datenbank Upgrade Test Einige bestehende Datenbank Funktionalitäten verwenden Flashback Database implizit: Snapshot Standby Reinstanziierung der Standby (z.B. bei Fast Start Failover) Obwohl diese Funktionalität gerade für Standby Systeme und Testsysteme bestens geeignet ist, gibt es eine gewisse Zurückhaltung Flashback Database einzusetzen. Eine Ursache ist oft die Angst vor zusätzlicher Last, die das Schreiben der Flashback Logs erzeugt, sowie der zusätzlich benötigte Plattenplatz. Dabei ist die Last im Normalfall relativ gering (ca. 5%) und auch der zusätzlich benötigte Platz für die Flashback Logs lässt sich relativ genau bestimmen. Ebenfalls wird häufig nicht beachtet, dass es auch ohne das explizite Einschalten der Flashback Logs möglich ist, einen garantieren Rücksetzpunkt (Guaranteed Restore Point kurz GRP) festzulegen, und die Datenbank dann auf diesen Restore Point zurückzusetzen. Das Setzen eines garantierten Rücksetzpunktes funktioniert in 11gR2 im laufenden Betrieb. Wie dies genau funktioniert, welche Unterschiede es zum generellen Einschalten von Flashback Logs gibt, wie man Flashback Database monitoren kann und was es sonst noch zu berücksichtigen gibt, damit beschäftigt sich dieser Tipp.

• PCI Compliance Book Suggestion

  - by Joel Weise

  I am always looking for good books on security, compliance and of course, PCI.  Here is one I think you will find very useful. "PCI Compliance, Third Edition: Understand and Implement Effective PCI Data Security Standard Compliance" by Branden Williams and Anton Chuvakin.  [Fair disclosure - Branden and I work together on the Information Systems Security Association Journal's editorial board.]   The primary reason I like this book is that the authors take a holistic architectural approach to PCI compliance and that to me is the most safe and sane way to approach PCI.  Using such an architectural approach to PCI is, in my humble opinion, the underlying intent of PCI.  Don't create a checklist of the PCI DSS and then map a solution to each.  That is a recipe for disaster.  Instead, look at how the different components and their configurations work together in a synergistic fashion.  In short, create a security architecture and governance framework (the ISO 27000 series is a good place to start) that begins with an evaluation of the requirements laid down in the PCI DSS, as well as your other applicable compliance, business and technical requirements.  By developing an integrated security architecture you should be able to not only address current requirements, but also be in a position to quickly address future ones as well.

• Are R&D mini-projects a good activity for interns?

  - by dukeofgaming

  I'm going to be in charge of hiring some interns for our software department soon (automotive infotainment systems) and I'm designing an internship program. The main productive activity "menu" I'm planning for them consists of: Verification testing Writing Unit Tests (automated, with an xUnit-compliant framework [several languages in our projects]) Documenting Code Updating wiki Updating diagrams & design docs Helping with low priority tickets (supervised/mentored) Hunting down & cleaning compiler/run-time warnings Refactoring/cleaning code against our coding standards But I also have this idea that having them do small R&D projects would be good to test their talent and get them to have fun. These mini-projects would be: Experimental implementations & optimizations Proof of concept implementations for new technologies Small papers (~2-5 pages) doing formal research on the previous two points Apps (from a mini-project pool) These kinds of projects would be pre-defined and very concrete, although new ideas from the interns themselves would be very welcome. Even if a project is too big or is abandoned, the idea would also be to lay the ground work so they can be retaken by another intern or intern team. While I think this is good in concept, I don't know if it could be good in practice, as obviously this would diminish their productivity on "real work" (work with immediate value to the company), but I think it could help bring aboard very bright people and get them to want to stay in the future (which, I think, is the end goal for any internship program). My question here is if these activities are too open ended or difficult for the average intern to accomplish and if R&D is an efficient use of an interns time or if it makes more sense for to assign project work to interns instead.

• Regulation of the software industry

  - by Flexo

  Every few years someone proposes tighter regulation for the software industry. This IEEE article has been getting some attention lately on the subject. If software engineers who write programs for systems that expose the public to physical or financial risk knew they would be tested on their competence, the thinking goes, it would reduce the flaws and failures in code—and maybe save a few lives in the bargain. I'm skeptical about the value and merit of this. To my mind it looks like a land grab by those that proposed it. The quote that clinches that for me is: The exam will test for basic knowledge, not mastery of subject matter because the big failures (e.g. THERAC-25) seem to be complex, subtle issues that "basic knowledge" would never be sufficient to prevent. Ignoring any local issues (such as existing protections of the title Engineer in some jurisdictions): The aims are noble - avoid the quacks/charlatans1 and make that distinction more obvious to those that buy their software. Can tighter regulation of the software industry ever achieve it's original goal? 1 Exactly as regulation of the medical profession was intended to do.

• Intel 5100 AGN disconnects and then disables my Verizon FiOS Actiontec router

  - by Anthony

  I am a new user (my first trial) of Ubuntu and booted up my Windows Vista laptop up with the Ubuntu CD. I was able to connect wirelessly to my router and stay connected for about a minute. After that it would disconnect and my router would be disabled: none of my other wireless devices would see the signal any longer, as if it disappeared. I would have to cycle the router's power toggle off/on to get it to come back on and put out a signal again. This happened repeatedly. I experienced no other problems trying the software (i.e., accessed my files w/o issue). I did not attempt to connect with an Ethernet cable. Here are the specs on my system: laptop is HP Pavilion dv5 Notebook PC system type is 64-bit operating system CPU is Intel Core 2 Duo P8600 2.4GHz ram is 4 GB network card is Intel WiFi Link 5100 AGN I read elsewhere in this forum that 64-bit systems may not be compatible with Ubuntu. Can anyone help me with this? I'd really like to be able to use this op system.

• Are you ready to take a walk in the clouds?

  - by Steve Loethen

  Cloud computing is here, whether we want it or not.  When I say "a walk in the clouds” I am not talking about a pleasant romantic comedy, but a real alternative to hosting applications on-premise.  For years we have had the power to host our web sites on remote systems.  Sure, challenges existed.  Mostly web sites.  I could, with a few clicks, create a account at a myriad of web host sites, put my site in the hands of a remote hosting company, and boom, I was a site on the internet.  But choices, power, and management was limited. Now, we have a set of services to let us approach and power and control we love, but with scalability of the data center.  My personal web site is hosted on a laptop running hyperV in my basement.  I have to manage the machine, patch it, make sure it is powered up.  This is fine for the “hello, this is my dog skippy site” that I maintain. If the football pool I run has an issue, one of the 10 users I have calls or emails me and I go check it out.  All is well. But this falls well below the needs of even the simplest of enterprises.  A business needs a stronger datacenter, a better pipe to the world.  Do I really want to base my business on a dynamic dns and a dsl line from the local phone company? Cloud computing gives us most of what I value (control, a db of my own, updating my site from Visual Studio). Come learn how this technology can transform your business.  If you are a Microsoft shop, or are interested in Microsoft in the cloud, on April 8 and 9, a 2 day free Azure training class is being conducted in Kansas City.  http://www.azurebootcamp.com/city/kansascity Hope to see you there.  If you come, make sure you look me up.

• Hosting and domain registrations for multiple clients under a single hosting account of mine?

  - by letseatfood

  I am finally getting regular work designing, developing, and deploying websites for small businesses and individuals. So far the websites utilize single-user content management systems, so the websites create, as far as I know, minimal load on the shared servers. I have always required that each of my clients purchase annual shared hosting at Dreamhost. For domain registration, I ask that they register with Dreamhost, but some already have a registered domain elsewhere and this is fine with me. I do this so the billing issues are the client's responsibility, not mine. My question is: Since I can register unlimited domains and connect them to my one shared hosting account at Dreamhost, should I not be requiring clients to individually pay for shared hosting and a domain? Should I actually be paying for one hosting account and then hosting all of my client's websites on that account? As I said before, I currently have each client buy their own hosting, because I feel that, for example, if there is high traffic to their site, there would be less a chance of the site going down than if their site was hosted with many others on one account. I am famous for being long-winded, please let me know if I can clarify at all. Thanks!

• Relation between developers and clients

  - by guiman

  Hi everyone, i've been facing a situation at work and i would like to share it with you and tell me: Did you had to do it to? Should a developer be in direct contact wit the client? Or there should be an "adapter" guy that translates client needs in pseudo formal requirements understandable to us? I'm currently working in a small company that its taking care of implementing lots of systems, most of them for goverment institutions, in witch it generally means taking software developted 20 years ago and refurbish them so fit up-to-date needs. The clients generally are very used to them and tend to discourage change (they are in their 50s 60s give or take, so not technologie-friendly in general). As you can imagine, dev-team in most cases starts taking care of relation with clients, generating the documentation needed in this cases (CU usually), assisting to weekly meets to see improvements with clients. As for experience, this is a gold mine for me, because gives a nice perspective on all the aspects of software development, but also some problems rise because, if developers come from mars then client are from venus. So there is a fine gap on the vocabulary/experience/capability-to-interpret-needs that generates an noice in the communication, and some times affecting the final product.

• Process Improvement and the Data Professional

  - by BuckWoody

  Don’t be afraid of that title – I’m not talking about Six Sigma or anything super-formal here. In many organizations, there are more folks in other IT roles than in the Data Professional area. In other words, there are more developers, system administrators and so on than there are the “DBA” role. That means we often have more to do than the time we need to do it. And, oddly enough, the first thing that is sacrificed is process improvement – the little things we need to do to make the day go faster in the first place. Then we get even more behind, the work piles up and…well, you know all about that. Earlier I challenged you to find 10-30 minutes a day to study. Some folks wrote back and asked “where do I start”? Well, why not be super-efficient and combine that time with learning how to make yourself more efficient? Try out a new scripting language, learn a new tool that automates things or find out ways others have automated their systems. In general, find out what you’re doing and how, and then see if that can be improved. It’s kind of like doing a performance tuning gig on yourself! If you’re pressed for time, look for bite-sized articles (like the ones I’ve done here for PowerShell and SQL Server) that you can follow in a “serial” fashion. In a short time you’ll have a new set of knowledge you can use to make your day faster. Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

• Dual monitor setup can cause boot problem?

  - by kriszpontaz

  I have a two monitor setup, one 22" (1680x1050 res., 16:10) and another 19" (1280x1024 res. 5:4). I've installed ubuntu 11.10 beta2 x86, and the installation worked fine, the system boot was successful. I've upgraded ubuntu from the main server, and after restart, booting with the kernel 3.0.0-13, my system hangs up with a purple screen, and than nothing happens (the system boots successful with the kernel image 3.0.0-8). Nvidia current drivers not installed, but if i install it, the situation is the same. I have an Nvidia 9600GT installed. I tried to boot with one screen attached, I've tried each port, but no luck at all. With kernel image 3.0.0-8 the system successfully boots with each display attached, but the farther kernels (3.0.0-11; 3.0.0-12; ect.) all freezes, even one display, or multiple attached. I have two systems with ubuntu installed, and the other (with Ati HD 2400XT, latest closed drivers) don't have any issues like this, I wrote about. Update: The problem solved by reinstalling the operatin system, without automatically installing updates during install, with only one monitor attached. After completing installation, and clean reboot, i've installed closed nVidia drivers. After all, i found it's safe to connect another monitor to the system, it's not causing any problems. Probably the situation stays like this.

• In MVC , DAO should be called from Controller or Model

  - by tito

  I have seen various arguments against the DAO being called from the Controller class directly and also the DAO from the Model class.Infact I personally feel that if we are following the MVC pattern , the controller should not coupled with the DAO , but the Model class should invoke the DAO from within and controller should invoke the model class.Why because , we can decouple the model class apart from a webapplication and expose the functionalities for various ways like for a REST service to use our model class. If we write the DAO invocation in the controller , it would not be possible for a REST service to reuse the functionality right ? I have summarized both the approaches below. Approach #1 public class CustomerController extends HttpServlet { proctected void doPost(....) { Customer customer = new Customer("xxxxx","23",1); new CustomerDAO().save(customer); } } Approach #2 public class CustomerController extends HttpServlet { proctected void doPost(....) { Customer customer = new Customer("xxxxx","23",1); customer.save(customer); } } public class Customer { ........... private void save(Customer customer){ new CustomerDAO().save(customer); } } Note- Here is what a definition of Model is : Model: The model manages the behavior and data of the application domain, responds to requests for information about its state (usually from the view), and responds to instructions to change state (usually from the controller). In event-driven systems, the model notifies observers (usually views) when the information changes so that they can react. I would need an expert opinion on this because I find many using #1 or #2 , So which one is it ?
