• Java EE 7 turns one today!

  - by delabassee

  "Tell me and I forget. Teach me and I remember. Involve me and I learn." (Benjamin Franklin) Today marks the first year anniversary of Java EE 7. The JSR 342 specification was finalised on May 28, 2013 with the official launch taking place on June 12, 2013 (original press release). As of today, there are already 3 Java EE 7 compatible Application Servers, coming from different 'vendors' (Oracle, TmaxSoft and Red Hat). Two of those Java EE 7 Application Servers are free and open source. We expect the list of Java EE 7 compatible Application Servers to grow over the coming months. Source: RebelLabs - 'Java Tools and Technologies Landscape for 2014' According to a recent independent survey, one third of the Java EE users who participated in that survey is already using Java EE 7. This is a good sign but it also means that a lot of people are not yet on Java EE 7. So if you haven't yet embarked on Java EE 7, now is really the time to do so! There are various ways to learn Java EE 7, in no particular order ... Continue to read The Aquarium. Through this blog, we are relaying Java EE news but we are also doing our best to highlight relevant technical contents such as articles, community tutorials, etc. Watch the GlassFish YouTube channel. Amongst others, it contains the different videos of the Java EE 7 launch, those videos will give you good technical update on Java EE and its different components specifications (JMS 2.0, JAX-RS 2.0, EJB 3.2, etc.) Take a formal training. Oracle University is starting to roll-out Java EE 7 trainings like the 'Java EE 7: New Features' class.  Attend conferences and JUGs sessions. On that note, we have spent a lot of time to create a strong JavaOne 'Server-Side Java' track. It's still possible to benefit from the early bird JavaOne pricing but don't wait too much! Read books. There are more than 25 (!) books related to Java EE 7 or to one of the Java EE 7 component specification.  There are many more ways to learn Java EE but if I have to suggest one and only one way, I would recommend the Java EE 7 Tutorial. It's exhaustive and clear, it's free and it continues to evolve. And finally as the introductory quote suggest, participation is key to learning. Participate in JUGs,  participate in Adopt-a-JSR, get involved in the different open source communities evolving around Java EE, participate in the JCP... in one word, participate!

• Java Dynamic Binding

  - by Chris Okyen

  I am having trouble understanding the OOP Polymorphic principl of Dynamic Binding ( Late Binding ) in Java. I looked for question pertaining to java, and wasn't sure if a overall answer to how dynamic binding works would pertain to Java Dynamic Binding, I wrote this question. Given: class Person { private String name; Person(intitialName) { name = initialName; } // irrelevant methods is here. // Overides Objects method public void writeOutput() { println(name); } } class Student extends Person { private int studentNumber; Student(String intitialName, int initialStudentNumber) { super(intitialName); studentNumber = initialStudentNumber; } // irrellevant methods here... // overides Person, Student and Objects method public void writeOutput() { super.writeOutput(); println(studentNumber); } } class Undergaraduate extends Student { private int level; Undergraduate(String intitialName, int initialStudentNumber,int initialLevel) { super(intitialName,initialStudentNumber); level = initialLevel; } // irrelevant methods is here. // overides Person, Student and Objects method public void writeOutput() { super.writeOutput(); println(level); } } I am wondering. if I had an array called person declared to contain objects of type Person: Person[] people = new Person[2]; person[0] = new Undergraduate("Cotty, Manny",4910,1); person[1] = new Student("DeBanque, Robin", 8812); Given that person[] is declared to be of type Person, you would expect, for example, in the third line where person[0] is initialized to a new Undergraduate object,to only gain the instance variable from Person and Persons Methods since doesn't the assignment to a new Undergraduate to it's ancestor denote the Undergraduate object to access Person - it's Ancestors, methods and isntance variables... Thus ...with the following code I would expect person[0].writeOutput(); // calls Undergraduate::writeOutput() person[1].writeOutput(); // calls Student::writeOutput() person[0] to not have Undergraduate's writeOutput() overidden method, nor have person[1] to have Student's overidden method - writeOutput(). If I had Person mikeJones = new Student("Who?,MikeJones",44,4); mikeJones.writeOutput(); The Person::writeOutput() method would be called. Why is this not so? Does it have to do with something I don't understand about relating to arrays? Does the declaration Person[] people = new Person[2] not bind the method like the previous code would?

• Is throwing an error in unpredictable subclass-specific circumstances a violation of LSP?

  - by Motti Strom

  Say, I wanted to create a Java List<String> (see spec) implementation that uses a complex subsystem, such as a database or file system, for its store so that it becomes a simple persistent collection rather than an basic in-memory one. (We're limiting it specifically to a List of Strings for the purposes of discussion, but it could extended to automatically de-/serialise any object, with some help. We can also provide persistent Sets, Maps and so on in this way too.) So here's a skeleton implementation: class DbBackedList implements List<String> { private DbBackedList() {} /** Returns a list, possibly non-empty */ public static getList() { return new DbBackedList(); } public String get(int index) { return Db.getTable().getRow(i).asString(); // may throw DbExceptions! } // add(String), add(int, String), etc. ... } My problem lies with the fact that the underlying DB API may encounter connection errors that are not specified in the List interface that it should throw. My problem is whether this violates Liskov's Substitution Principle (LSP). Bob Martin actually gives an example of a PersistentSet in his paper on LSP that violates LSP. The difference is that his newly-specified Exception there is determined by the inserted value and so is strengthening the precondition. In my case the connection/read error is unpredictable and due to external factors and so is not technically a new precondition, merely an error of circumstance, perhaps like OutOfMemoryError which can occur even when unspecified. In normal circumstances, the new Error/Exception might never be thrown. (The caller could catch if it is aware of the possibility, just as a memory-restricted Java program might specifically catch OOME.) Is this therefore a valid argument for throwing an extra error and can I still claim to be a valid java.util.List (or pick your SDK/language/collection in general) and not in violation of LSP? If this does indeed violate LSP and thus not practically usable, I have provided two less-palatable alternative solutions as answers that you can comment on, see below. Footnote: Use Cases In the simplest case, the goal is to provide a familiar interface for cases when (say) a database is just being used as a persistent list, and allow regular List operations such as search, subList and iteration. Another, more adventurous, use-case is as a slot-in replacement for libraries that work with basic Lists, e.g if we have a third-party task queue that usually works with a plain List: new TaskWorkQueue(new ArrayList<String>()).start() which is susceptible to losing all it's queue in event of a crash, if we just replace this with: new TaskWorkQueue(new DbBackedList()).start() we get a instant persistence and the ability to share the tasks amongst more than one machine. In either case, we could either handle connection/read exceptions that are thrown, perhaps retrying the connection/read first, or allow them to throw and crash the program (e.g. if we can't change the TaskWorkQueue code).

• What's the best way to create a static utility class in python? Is using metaclasses code smell?

  - by rsimp

  Ok so I need to create a bunch of utility classes in python. Normally I would just use a simple module for this but I need to be able to inherit in order to share common code between them. The common code needs to reference the state of the module using it so simple imports wouldn't work well. I don't like singletons, and classes that use the classmethod decorator do not have proper support for python properties. One pattern I see used a lot is creating an internal python class prefixed with an underscore and creating a single instance which is then explicitly imported or set as the module itself. This is also used by fabric to create a common environment object (fabric.api.env). I've realized another way to accomplish this would be with metaclasses. For example: #util.py class MetaFooBase(type): @property def file_path(cls): raise NotImplementedError def inherited_method(cls): print cls.file_path #foo.py from util import * import env class MetaFoo(MetaFooBase): @property def file_path(cls): return env.base_path + "relative/path" def another_class_method(cls): pass class Foo(object): __metaclass__ = MetaFoo #client.py from foo import Foo file_path = Foo.file_path I like this approach better than the first pattern for a few reasons: First, instantiating Foo would be meaningless as it has no attributes or methods, which insures this class acts like a true single interface utility, unlike the first pattern which relies on the underscore convention to dissuade client code from creating more instances of the internal class. Second, sub-classing MetaFoo in a different module wouldn't be as awkward because I wouldn't be importing a class with an underscore which is inherently going against its private naming convention. Third, this seems to be the closest approximation to a static class that exists in python, as all the meta code applies only to the class and not to its instances. This is shown by the common convention of using cls instead of self in the class methods. As well, the base class inherits from type instead of object which would prevent users from trying to use it as a base for other non-static classes. It's implementation as a static class is also apparent when using it by the naming convention Foo, as opposed to foo, which denotes a static class method is being used. As much as I think this is a good fit, I feel that others might feel its not pythonic because its not a sanctioned use for metaclasses which should be avoided 99% of the time. I also find most python devs tend to shy away from metaclasses which might affect code reuse/maintainability. Is this code considered code smell in the python community? I ask because I'm creating a pypi package, and would like to do everything I can to increase adoption.

• Explanation of the definition of interface inheritance as described in GoF book

  - by Geek

  I am reading the first chapter of the Gof book. Section 1.6 discusses about class vs interface inheritance: Class versus Interface Inheritance It's important to understand the difference between an object's class and its type. An object's class defines how the object is implemented.The class defines the object's internal state and the implementation of its operations.In contrast,an object's type only refers to its interface--the set of requests on which it can respond. An object can have many types, and objects of different classes can have the same type. Of course, there's a close relationship between class and type. Because a class defines the operations an object can perform, it also defines the object's type . When we say that an object is an instance of a class, we imply that the object supports the interface defined by the class. Languages like c++ and Eiffel use classes to specify both an object's type and its implementation. Smalltalk programs do not declare the types of variables; consequently,the compiler does not check that the types of objects assigned to a variable are subtypes of the variable's type. Sending a message requires checking that the class of the receiver implements the message, but it doesn't require checking that the receiver is an instance of a particular class. It's also important to understand the difference between class inheritance and interface inheritance (or subtyping). Class inheritance defines an object's implementation in terms of another object's implementation. In short, it's a mechanism for code and representation sharing. In contrast,interface inheritance(or subtyping) describes when an object can be used in place of another. I am familiar with the Java and JavaScript programming language and not really familiar with either C++ or Smalltalk or Eiffel as mentioned here. So I am trying to map the concepts discussed here to Java's way of doing classes, inheritance and interfaces. This is how I think of of these concepts in Java: In Java a class is always a blueprint for the objects it produces and what interface(as in "set of all possible requests that the object can respond to") an object of that class possess is defined during compilation stage only because the class of the object would have implemented those interfaces. The requests that an object of that class can respond to is the set of all the methods that are in the class(including those implemented for the interfaces that this class implements). My specific questions are: Am I right in saying that Java's way is more similar to C++ as described in the third paragraph. I do not understand what is meant by interface inheritance in the last paragraph. In Java interface inheritance is one interface extending from another interface. But I think the word interface has some other overloaded meaning here. Can some one provide an example in Java of what is meant by interface inheritance here so that I understand it better?

  - by preishuber

  After nearly 7 years I will discontinue blogging on this site. My resources are limited. You can reach my German blog which is used to support my customers. Looking back to a long an interesting journey ASP.NET by ScottGu That was the reason to attend this site and support Microsoft as much as I can. For that I was honored as ASP.NET MVP- thanks again. Meet Scoot several times. Great guy! Forums I have left NNTP forums a few years ago and now Microsoft closed it- It was my idea ;-) AJAX Was the wrong way- JQuery won the game IIS7 That is really a great plattform and the IIS team rules. I am sad that is so silent around that topic. ASP.NET after 2.0 Is no longer my world. I love ASP.NET and ASP.NET Server controls. I hate the discussion about how to follow the holy rules of MVC. Microsoft have dropped the goal to bring ASP.NET to #1 and accepted PHP is it. Facebook & Twittering Microblogging takes over a part of the blogging business. Shorter faster cheaper- or as SteveB mentioned - do more with less. Google Google is taking over the web. I am using Bing every time as I can but Google have more options. Sorry Microsoft you will loose that game. Apple That is not the biggest problem of Microsoft. the Ixxx takes over a small part but big money of the market, but the customers are not strongly linked. New wave new hype- Game over Apple. Silverlight My new home. I can reuse a lot of my skills and love the possibilitys. Silverligth will passing WPF-and strike Flash Windows phone 7 Also my skills fit. I just will use it for fun. I am not really satisfied about what I have heard from MIX. Guys from Redmond, I am sad to say you have been the best Smartphone OS and lost everything. The ADO vNext Story That will be the next mystic point. WCF, REST, JSON, ATOM and now OData. Nothing about SQL commands. LINQ, ORM is also not the final solution for multilayered disconnected async scenarios.

• GUI device for throwing a ball

  - by Fredrik Johansson

  The hero has a ball, which shall be thrown with accuracy in a court on iPhone/iPad. The player is seen from above, in a 2D view. In game play, the player reach is between 1/15 and 1/6 of the height of the iPhone screen. The player will run, and try to outmaneuver his opponent, and then throw the ball at a specific location, which is guarded by the opponent (which is also shown on the screen). The player is controlled by a joystick, and that works ok, but how shall I control the stick? Maybe someone can propose a third control method? I've tried the following two approaches: Joystick: Hero has a reach of 1 meter, and this reach is marked with a semi-opaque circle around the player. The ball can be moved by a joystick. When the joystick is moved south, the ball is moved south within the reach circle. There is a direct coupling with the joystick and the position of the ball. I.e. when the joystick is moved max south, the ball is max south within the player reach. At each touch update the speed is calculated, and the Box2d ball position and ball speed are updated. NB, the ball will never be moved outside the reach as long as the player push the joystick. The ball is thrown by swiping the joystick to make the ball move, and then releasing the joystick. At release, the ball will get a smoothed speed of the joystick. Joystick Problem: The throwing accuracy gets bad, because the joystick can not be that big, and a small movement results in quite a large movement of the ball. If the user does not release before the end of the joystick maximum end point, the ball will stop, and when the user releases the joystick the speed of the ball will be zero. Bad... Touch pad A force is applied to the ball by a sweep on a touchpad. The ball is released when the sweep is ended, or when the ball is moved outside the player reach. As there is no one to one mapping between the swipe and the ball position, the precision can be improved. A large swipe can result in a small ball movement. Touch Pad Problem A touchpad is less intuitive. Users do not seem to know what to do with the touch pad. Some tap the touchpad, and then the ball just falls to the ground. As there is no one-to-one mapping, the ball can be moved outside the reach, and then it will just fall to the ground. It's a bit hard to control the ball, especially if the player also moves.

• JUDCon 2013 Trip Report

  - by reza_rahman

  JUDCon (JBoss Users and Developers Conference) 2013 was held in historic Boston on June 9-11 at the Hynes Convention Center. JUDCon is the largest get together for the JBoss community, has gone global in recent years but has it's roots in Boston. The JBoss folks graciously accepted a Java EE 7 talk from me and actually referenced my talk in their own sessions. I am proud to say this is my third time speaking at JUDCon/the Red Hat Summit over the years (this was the first time on behalf of Oracle). I had great company with many of the rock stars of the JBoss ecosystem speaking such as Lincoln Baxter, Jay Balunas, Gavin King, Mark Proctor, Andrew Lee Rubinger, Emmanuel Bernard and Pete Muir. Notably missing from JUDCon were Bill Burke, Burr Sutter, Aslak Knutsen and Dan Allen. Topics included Java EE, Forge, Arquillian, AeroGear, OpenShift, WildFly, Errai/GWT, NoSQL, Drools, jBPM, OpenJDK, Apache Camel and JBoss Tools/Eclipse. My session titled "JavaEE.Next(): Java EE 7, 8, and Beyond" went very well and it was a full house. This is our main talk covering the changes in JMS 2, the Java API for WebSocket (JSR 356), the Java API for JSON Processing (JSON-P), JAX-RS 2, JPA 2.1, JTA 1.2, JSF 2.2, Java Batch, Bean Validation 1.1, Java EE Concurrency and the rest of the APIs in Java EE 7. I also briefly talked about the possibilities for Java EE 8. The slides for the talk are here: JavaEE.Next(): Java EE 7, 8, and Beyond from reza_rahman Besides presenting my talk, it was great to catch up with the JBoss gang and attend a few interesting sessions. On Sunday night I went to one of my favorite hangouts in Boston - the exalted Middle East Club as Rolling Stone refers to it (other cool spots in an otherwise pretty boring town is "the Church"). As contradictory as it might sound to the uninitiated, the Middle East Club is possibly the best place in Boston to simultaneously get great Middle Eastern (primarily Lebanese) food and great underground metal. For folks with a bit more exposure, this is probably not contradictory at all given bands like Acrassicauda and documentaries like Heavy Metal in Baghdad. Luckily for me they were featuring a few local Thrash metal bands from the greater Boston area. It wasn't too bad considering it was primarily amateur twenty-something guys (although I'm not sure I'm a qualified critic any more since I all but stopped playing about at that age). It's great Boston has the Middle East as an incubator to keep the rock, metal, folk, jazz, blues and indie scene alive. I definitely enjoyed JUDCon/Boston and hope to be part of the conference next year again.

• TomEE Integration in NetBeans Next

  - by Geertjan

  At JavaOne 2013, there was a lot of buzz around the TomEE server, e.g., many Tweets, nice party, and a new TomEE consulting company. For those tracking TomEE developments, it is interesting to note that recently the NetBeans IDE development builds have had added to them... TomEE support. Note: The TomEE support described here is not in NetBeans IDE 7.4, but in development builds for the next release of NetBeans IDE.For example, with NetBeans IDE development builds you're able to: register TomEE as a server in the Services window (TomEE has several distributions, e.g., one can use the "with JAX-RS" one, for example) create a Java EE 6 web project (e.g., Maven based) against this server create JPA entities from database create JAX-RS classes from JPA entities create JSF pages from JPA entities the IDE lets you create a new data source for TomEE and deploy it to the server the IDE figures out the components that are already packaged in TomEE, and the fact that (unlike with regular Tomcat), it does not need to package any components such as JSF implementation, persistence provider, or JAX-RS runtime, so that the resulting WAR file is very small the IDE can also do "deploy on save" with TomEE, so that your development cycle is very fast Adam Bien blogged about how he set up TomEE sometime ago, here. The official support in NetBeans IDE will be much more tightly integrated, simplifying the steps Adam describes. For example, the IDE does step 2 from Adam's blog for you, i.e., it sets up TomEE deployment roles. Moreover, it knows about all the technologies included in TomEE so that it can optimize the packaging; it knows about TomEE's persistence setup; it can work with TomEE data sources, etc. Below you see a Maven-based Java EE 6 PrimeFaces application (all entities and JSF pages generated from a database) deployed to TomEE in NetBeans IDE: And here's the management console for configuring and finetuning TomEE in NetBeans IDE: When I tried out the NetBeans IDE development build and TomEE, to see how everything fits together, I was surprised at how fast TomEE started up. Not sure what they did to it, but seems like a server on steroids. And setting it up in NetBeans IDE was trivial. Add the simple set up of TomEE in NetBeans IDE to the many benefits that the widely praised out of the box NetBeans Maven tools make possible, together with the fact that not one single plugin had to be installed to get everything you see described here up and running... and you have a really powerful combination of dev tools, all for free.

The call for papers begins  on December 1st for Devoxx in London and Paris.  Speakers will be able to present at the two  conferences in the same week. Oracle committed  to fully sponsor the three Devoxx conferences in  2013 with a platinum sponsorship. Over 5,000 developers are expected to attend those conferences. Five dancing NAO robots welcomed attendees at the keynote. Stephan Janssen offers the JUGs to replicate Devoxx4kids workshops using his content and web infrastructure.  He recommended organizing kid events because “the workshops were really fun and such rewarding experience.” Stephan also announced the redesign of Parleys with Html 5 and GlassFish. Friendlier to speakers, they will be able to post their slides online before their talks and then sync the talk's sound track with the slides. Nandini Ramani, VP of product development explained in her keynote address the growing role of Java from enterprise application development to cloud computing to embedded machine-to-machines systems. “Java continues to drive the applications and devices that enrich our interactivity with the world around us” she said. The Java platform has expanded its reach with the OS X and Linux ARM support on Java SE and with two new releases, Java SE embedded and Java embedded Suite 7.0 middleware platform.  Coming up next year is JDK 8, which will include Project Lambda, Project Nashorn and more. As part of that release, JavaFX will offer 3D and third-party component integration. At Devoxx, the slick and interactive schedules were designed with JavaFX. The earliest version of the Java EE 7 SDK is available for download and has WebSocket support, improved JSON support and more.  Stephen Chin arrived on stage with his bike, ending his European NightHacking tour.

• Windows8, JavaScript and HTML5 - A good thing?

  - by Albers

  Most of us have seen the Windows 8 news regarding support for native HTML5/JavaScript applications. The press has pushed this as a potential threat to the .NET developer community because JavaScript and HTML5 were called "our new developer platform". The press release refers to "Web-connected and Web-powered apps built using HTML5 and JavaScript that have access to the full power of the PC.".Microsoft has also been hush on details related to these comments. Before we buy the hype and start worrying about a world where we drop our Visual Studio licenses and buy DreamWeaver - let's think about how Windows 8 HTML/JavaScript applications would be implemented. The HTML5 spec offers support for offline applications, but this won't offer the OS-integrated experience the press release refers to. MS has to be planning a way to extend access beyond the traditional JavaScript feature set. Microsoft has a similar option today: HTML Applications or HTAs. They come close to required features, but HTAs need ActiveX or Java integration to provide the promised OS-level access. I'm guessing that Microsoft's future OS strategy isn't built on developers cranking out ActiveX controls or Java applets. So where is Microsoft headed? One possibility is that MS builds a new JavaScript framework from the ground up outside their current APIs. Another idea would be for Microsoft to add support for JavaScript as a first class .NET language using the Dynamic Language Runtime. A solution based on the DLR could be integrated into an HTA-like model to provide the promised access, along with the full range of features in .NET Framework. Security comes included in the Framework. And the work necessary to support this integration would tie in nicely with the effort MS has recently made providing better JavaScript and HTML5 support in Visual Studio 2010. As a bonus, a full-fledged JavaScript DLR implementation would allow single language web solutions across client and server (think node.js) and would appeal to developers who are familiar with JavaScript but have less experience with the Microsoft tech stack. We will all get a better picture after the Build conference in September. But in the mean time we know that Microsoft has a reputation for providing strong developer support. We might want to reserve our harshest judgement and consider that the press release could hint at new opportunities for .NET development.

• BizTalk 2009 - SQL Server Job Configuration

  - by StuartBrierley

  Following the installation of Biztalk Server 2009 on my development laptop I used the BizTalk Server Best Practice Analyser which highlighted the fact that two of the SQL Server Agent jobs that BizTalk relies on were not running successfully.  Upon investigation it turned out that these jobs needed to be configured before they would run successfully. To configure these jobs open SQL Server Management Studio, expand SQL Server Agent > Jobs and double click on the appropriate job.  Select Steps and then edit the appropriate entries. Backup BizTalk Server (BizTalkMgmtDb) This job is comprised of three steps BackupFull, MarkAndBackupLog and ClearBackupHistory. BackupFull exec [dbo].[sp_BackupAllFull_Schedule] ‘d’ /* Frequency */,‘BTS’ /* Name */,‘<destination path>’ /* location of backup files */ The frequency here is set/left as daily The name is left as BTS You must provide a full destination path for the backup files to be stored. There are also two optional parameters: A flag that controls if the job forces a full backup if a partial backup fails A parameter to control the time of day to run the full backup; the default is midnight UTC time For example: exec [dbo].[sp_BackupAllFull_Schedule] ‘d’ /* Frequency */,‘BTS’ /* Name */,‘<destination path>’ /* location of backup files */ , 0, 22 MarkAndBackUpLog exec [dbo].[sp_MarkAll] ‘BTS’ /* Log mark name */,’<destination path>’  /*location of backup files */ You must provide a destination path for the log backups. Optionally you can also add an extra parameter that tells the procedure to use local time: exec [dbo].[sp_MarkAll] ‘BTS’ /* Log mark name */,’<destination path>’  /*location of backup files */ ,1 Clear Backup History exec [dbo].[sp_DeleteBackupHistory] @DaysToKeep=7 This will clear out the instances in the MarkLog table older than 7 days.    DTA Purge and Archive (BizTalkDTADb) This job is comprised of a single step. Archive and Purge exec dtasp_BackupAndPurgeTrackingDatabase 0, --@nLiveHours tinyint, 1, --@nLiveDays tinyint = 0, 30, --@nHardDeleteDays tinyint = 0, null, --@nvcFolder nvarchar(1024) = null, null, --@nvcValidatingServer sysname = null, 0 --@fForceBackup int = 0 Any completed instance that is older than the live days plus live hours will be deleted, as will any associated data. Any data older than the HardDeleteDays will be deleted - this means that those long running orchestration instances that would otherwise never be purged will at some point have their data cleared down while allowing the instance to continue, thus preventing the DTA databse from growing indefinitely.  This should always be greater than the soft purge window. The NVC folder is the path for the backup files, if this is null the job will not run failing with the error : DTA Purge and Archive (BizTalkDTADb) Job failed SQL Server Management Studio, job activity monitor, view history The @nvcFolder parameter cannot be null. Archive and Purge step How long you choose to keep instances in the Tracking Database is really up to you. For development I have set this up as: exec dtasp_BackupAndPurgeTrackingDatabase 0, 1, 30, ’<destination path>’, null, 0 On a live server you may want to adjust these figures: exec dtasp_BackupAndPurgeTrackingDatabase 0, 15, 20, ’<destination path>’, null, 0

mso-style-unhide:no; mso-tstyle-shading:#F7CBC7; mso-tstyle-shading-themecolor:accent6; mso-tstyle-shading-themetint:63;} It is generally accepted among business communities that technology by itself is not a silver bullet to all problems, but when it is combined with leading practices, strategy, careful planning and execution, it can create a recipe for success. This post attempts to highlight some of the best practices along with dos & don’ts that our practice has accumulated over the years in the identity & access management space in general, and also in the context of R2, in particular. Best Practices The following section illustrates the leading practices in “How” to plan, implement and sustain a successful OIM deployment, based on our collective experience. Planning is critical, but often overlooked A common approach to planning an IAM program that we identify with our clients is the three step process involving a current state assessment, a future state roadmap and an executable strategy to get there. It is extremely beneficial for clients to assess their current IAM state, perform gap analysis, document the recommended controls to address the gaps, align future state roadmap to business initiatives and get buy in from all stakeholders involved to improve the chances of success. When designing an enterprise-wide solution, the scalability of the technology must accommodate the future growth of the enterprise and the projected identity transactions over several years. Aligning the implementation schedule of OIM to related information technology projects increases the chances of success. As a baseline, it is recommended to match hardware specifications to the sizing guide for R2 published by Oracle. Adherence to this will help ensure that the hardware used to support OIM will not become a bottleneck as the adoption of new services increases. If your Organization has numerous connected applications that rely on reconciliation to synchronize the access data into OIM, consider hosting dedicated instances to handle reconciliation. Finally, ensure the use of clustered environment for development and have at least three total environments to help facilitate a controlled migration to production. If your Organization is planning to implement role based access control, we recommend performing a role mining exercise and consolidate your enterprise roles to keep them manageable. In addition, many Organizations have multiple approval flows to control access to critical roles, applications and entitlements. If your Organization falls into this category, we highly recommend that you limit the number of approval workflows to a small set. Most Organizations have operations managed across data centers with backend database synchronization, if your Organization falls into this category, ensure that the overall latency between the datacenters when replicating the databases is less than ten milliseconds to ensure that there are no front office performance impacts. Ingredients for a successful implementation During the development phase of your project, there are a number of guidelines that can be followed to help increase the chances for success. Most implementations cannot be completed without the use of customizations. If your implementation requires this, it’s a good practice to perform code reviews to help ensure quality and reduce code bottlenecks related to performance. We have observed at our clients that the development process works best when team members adhere to coding leading practices. Plan for time to correct coding defects and ensure developers are empowered to report their own bugs for maximum transparency. Many organizations struggle with defining a consistent approach to managing logs. This is particularly important due to the amount of information that can be logged by OIM. We recommend Oracle Diagnostics Logging (ODL) as an alternative to be used for logging. ODL allows log files to be formatted in XML for easy parsing and does not require a server restart when the log levels are changed during troubleshooting. Testing is a vital part of any large project, and an OIM R2 implementation is no exception. We suggest that at least one lower environment should use production-like data and connectors. Configurations should match as closely as possible. For example, use secure channels between OIM and target platforms in pre-production environments to test the configurations, the migration processes of certificates, and the additional overhead that encryption could impose. Finally, we ask our clients to perform database backups regularly and before any major change event, such as a patch or migration between environments. In the lowest environments, we recommend to have at least a weekly backup in order to prevent significant loss of time and effort. Similarly, if your organization is using virtual machines for one or more of the environments, it is recommended to take frequent snapshots so that rollbacks can occur in the event of improper configuration. Operate & sustain the solution to derive maximum benefits When migrating OIM R2 to production, it is important to perform certain activities that will help achieve a smoother transition. At our clients, we have seen that splitting the OIM tables into their own tablespaces by categories (physical tables, indexes, etc.) can help manage database growth effectively. If we notice that a client hasn’t enabled the Oracle-recommended indexing in the applicable database, we strongly suggest doing so to improve performance. Additionally, we work with our clients to make sure that the audit level is set to fit the organization’s auditing needs and sometimes even allocate UPA tables and indexes into their own table-space for better maintenance. Finally, many of our clients have set up schedules for reconciliation tables to be archived at regular intervals in order to keep the size of the database(s) reasonable and result in optimal database performance. For our clients that anticipate availability issues with target applications, we strongly encourage the use of the offline provisioning capabilities of OIM R2. This reduces the provisioning process for a given target application dependency on target availability and help avoid broken workflows. To account for this and other abnormalities, we also advocate that OIM’s monitoring controls be configured to alert administrators on any abnormal situations. Within OIM R2, we have begun advising our clients to utilize the ‘profile’ feature to encapsulate multiple commonly requested accounts, roles, and/or entitlements into a single item. By setting up a number of profiles that can be searched for and used, users will spend less time performing the same exact steps for common tasks. We advise our clients to follow the Oracle recommended guides for database and application server tuning which provides a good baseline configuration. It offers guidance on database connection pools, connection timeouts, user interface threads and proper handling of adapters/plug-ins. All of these can be important configurations that will allow faster provisioning and web page response times. Many of our clients have begun to recognize the value of data mining and a remediation process during the initial phases of an implementation (to help ensure high quality data gets loaded) and beyond (to support ongoing maintenance and business-as-usual processes). A successful program always begins with identifying the data elements and assigning a classification level based on criticality, risk, and availability. It should finish by following through with a remediation process. Dos & Don’ts Here are the most common dos and don'ts that we socialize with our clients, derived from our experience implementing the solution. Dos Don’ts Scope the project into phases with realistic goals. Look for quick wins to show success and value to the stake holders. Avoid “boiling the ocean” and trying to integrate all enterprise applications in the first phase. Establish an enterprise ID (universal unique ID across the enterprise) earlier in the program. Avoid major UI customizations that require code changes. Have a plan in place to patch during the project, which helps alleviate any major issues or roadblocks (product and database). Avoid publishing all the target entitlements if you don't anticipate their usage during access request. Assess your current state and prepare a roadmap to address your operations, tactical and strategic goals, align it with your business priorities. Avoid integrating non-production environments with your production target systems. Defer complex integrations to the later phases and take advantage of lessons learned from previous phases Avoid creating multiple accounts for the same user on the same system, if there is an opportunity to do so. Have an identity and access data quality initiative built into your plan to identify and remediate data related issues early on. Avoid creating complex approval workflows that would negative impact productivity and SLAs. Identify the owner of the identity systems with fair IdM knowledge and empower them with authority to make product related decisions. This will help ensure overcome any design hurdles. Avoid creating complex designs that are not sustainable long term and would need major overhaul during upgrades. Shadow your internal or external consulting resources during the implementation to build the necessary product skills needed to operate and sustain the solution. Avoid treating IAM as a point solution and have appropriate level of communication and training plan for the IT and business users alike. Conclusion In our experience, Identity programs will struggle with scope, proper resourcing, and more. We suggest that companies consider the suggestions discussed in this post and leverage them to help enable their identity and access program.

• My program at #MIX10

  - by Laurent Bugnion

  Getting ready to fly to Vegas and MIX10 is really an exciting time! It is also a very busy time, because we are working on a few projects that will be shown on stage, I have my presentation to prepare, and of course as always the book… though these days it has been a bit on the back burner to be honest ;) I arrive in Vegas on Sunday evening around 10PM, so I won’t be able to make it to the traditional IdentityMine dinner this year. I am sure it will be fun nonetheless! My session: Understanding the MVVM pattern http://live.visitmix.com/MIX10/Sessions/EX14 My session is scheduled on the first day, which is awesome, so I am crossing my fingers and hoping that the MIX team doesn’t change it at the last minute… The session will take place on Monday, the 15th of March, 2PM, Room Lagoon F Important: remember that the USA are moving to Summer time on Sunday, so don’t forget to adjust your watches!! Ask the Experts On Monday evening, I will attend the Ask the Experts event, which is taking place between 5Pm and 6:30PM in the main meal hall. This will be a great occasion to grab a beer and talk about code. The Commons MIX has a great place called the Commons, a great location to chill between sessions, and meet tons of interesting people. I love the Commons and plan to spend a lot of time there to meet as many people as I can. Parties I was invited to a few parties, and will do my best to avoid conflicts :) I plan to be at the following events: Silverlight Mixers on Monday evening Insiders MIX party on Tuesday Silverlight partner happy hour on Tuesday too This is a lot of fun, but at the same time we all know that the best value of a conference is to meet people face to face. This is just the right occasion.  And on Thursday… On Thursday I will be attending a Silverlight event at the Luxor. It will be a very busy day, perfect way to end the conference. I fly back home on Friday morning, but due to a long stop in Washington DC (where I intend to go downtown and take pictures… except if the weather is bad, in which case I will probably go to the museum of flight), I will reach home only on Sunday. Getting hold of me The best way to reach me during MIX is to send me a message on Twitter. I will regularly tweet my location at the conference, so make sure to come and meet me. I am eager to make new friends, to talk about the fantastic jobs we did in WPF and Silverlight over the past year and hear your war stories! http://www.twitter.com/lbugnion   Laurent Bugnion (GalaSoft) Subscribe | Twitter | Facebook | Flickr | LinkedIn

  First of all, sorry to ask this, I'm sure that this was asked so many times before. Second, sorry for the English, it's not my native language. And Third, thank you in advance. So, I hope the follow info will help, here's a log. http://www.alsa-project.org/db/?f=07089caf530494bc4bc23e1d1cd56b3a5fae03c6 I already check 'System - Preferences - Sound'.

• SQL Azure and Trust Services

  - by BuckWoody

  Microsoft is working on a new Windows Azure service called “Trust Services”. Trust Services takes a certificate you upload and uses it to encrypt and decrypt sensitive data in the cloud. Of course, like any security service, there’s a bit more to it than that. I’ll give you a quick overview of how you can use this product to protect data you send to SQL Azure. The primary issue with storing data in the cloud is that you are in an environment that isn’t under your control – in fact, that’s the benefit of being in a distributed computing environment in the first place. On premises you’re able to encrypt data you don’t want anyone else to see, using various methods such as passwords (not very strong) or certificates (stronger). When you use a certificate, it’s vital that you create (or procure) and protect it yourself. When you store data remotely, regardless of IaaS, PaaS or SaaS, you don’t own the machines where the data lives. That means if you use a certificate from the cloud vendor to encrypt the data, you have to trust that the data won’t be accessed by the vendor. In some cases having a signed agreement with the vendor that they won’t access your data is sufficient, in other cases that doesn’t meet the requirements your system has for security. With the new Trust Services service, the basic process is that you use a Portal to create a Trust Server using policies and other controls. You place a X.509 Certificate you create or procure in that server. Using the Software development Kit (SDK), the developer has access to an Application Layer Encryption Framework to set fields of data they want to encrypt. From there, the data can be stored in SQL Azure as a standard field – only it is encrypted before it ever arrives. The portion of the client software that decrypts the data uses the same service, so the authenticated user sees the data if they are allowed to do so. The data remains encrypted “at rest”.  You can learn more about this product and check it out in the SQL Azure labs at Microsoft Codename "Trust Services"

• One Week To Go: OTN Architect Day: Cloud Computing

  - by Bob Rhubart

  One week remains until OTN Architect Day: Cloud Computing kicks of at the spectacular Oracle HQ campus in Redwood Shores, CA. The event is free, and there is still time to register. When: Tuesday July 9, 2013 8:30am - 12:30pm Where: Oracle Conference Center350 Oracle Pkwy Redwood City, CA 94065 Register now. It's free! Here's the latest update to the event agenda: 8:30am - 9:00am Registration and Continental Breakfast 9:00am - 9:45am Keynote 21st Century IT | Dr. James Baty VP, Global Enterprise Architecture Program, Oracle Imagine a time long, long ago. A time when servers were certified and dedicated to specific applications, when anything posted on an enterprise web site was from restricted, approved channels, and when we tried to limit the growth of 'dirty' data and storage. Today, applications are services running in the muti-tenant hybrid cloud. Companies beg their customers to tweet them, friend them, and publicly rate their products. And constantly analyzing a deluge of Internet, social and sensor data is the key to creating the next super-successful product, or capturing an evil terrorist. The old IT architecture was planned, dedicated, stable, controlled, with separate and well-defined roles. The new architecture is shared, dynamic, continuous, XaaS, DevOps. This keynote session describes the challenges and opportunities that the new business / IT paradigms present to the IT architecture and architects. 9:45am - 10:30am Technical Session Oracle Cloud: A Case Study in Building a Cloud | Anbu Krishnaswami Enterprise Architect, Oracle Building a Cloud can be challenging thanks to the complex requirements unique to Cloud computing and the massive scale typically associated with Cloud. Cloud providers can take an Infrastructure as a Service (IaaS) approach and build a cloud on virtualized commodity hardware, or they can take the Platform as a Service (PaaS) path, a service-oriented approach based on pre-configured, integrated, engineered systems. This presentation uses the Oracle Cloud itself as a case study in the use of engineered systems, demonstrating how the technical design of engineered systems is leveraged for building PaaS and SaaS Cloud services and a Cloud management infrastructure. The presentation will also explore the principles, patterns, best practices, and architecture views provided in Oracle's Cloud reference architecture. 10:30 am -10:45 am Break 10:45am-11:30am Technical Session Database as a Service | Markus Michalewicz Senior Principal Product Manager Oracle Real Application Clusters (RAC) New applications are now commonly built in a Cloud model, where the database is consumed as a service, and many established business processes are beginning to migrate to database as a service (DBaaS). This adoption of DBaaS is made possible by the availability of new capabilities in the database that enable resource pooling, dynamic resource management, model-based provisioning, metered use, and effective quality-of-service controls. This session will examine the catalog of database services at a large commercial bank to understand how these capabilities are enabling DBaaS for a wide range of needs within the enterprise. 11:30 am - 12:00 pm Panel Q&A Dr. James Baty, Anbu Krishnaswami, and Markus Michalewicz respond to audience questions. Registration is free, but seating is limited, so register now.

• How to fix 'grub error file not found' when installing 12.04?

  - by Tomasz Grabowski

  i'm trying to install Ubuntu. I don't know if it is important, but i'm trying to install it on external HDD. In the end i have external bootable HDD which only displays: error: file not found grub recovery> From the beginning: I've downloaded ubuntu-12.04-desktop-i386.iso I've used LiLi USB Creator (LinuxLive) to create bootable pendrive from that image I've bootet from it, it works I've clicked "Try ubuntu", it works too. I've used GParted to look over drivers (disks) My primary embedded disk is seen as /dev/sda My attached external disk as /dev/sdb My PenDrive as /dev/sdc I've created partitions on /dev/sdb Fist partition for system (over 200GiB) Second was there already (it's xsf, and i don't want to touch it :P) Third is extended partition, with 1 locital partiton (10GiB) for swap I've started installation i've choose "somethin else" in ... i belive secound screeb then is selected /dev/sdb as boot disk for first partiton of /dev/sdb i set i want ext3 file system, i've check "formattin" checkbox, and mount path set to "/" firs logical partiton set as swap partition After installation finished, i restarted my computer. When i boot from my primary disc it's work ok, my previous operating system - vista - works ok. When i set my BIOS to boot from my external disc, i only get that message: error: file not found grub recovery> I've try to reinstall it, but didn't help... In desperation, i've try to read a bit about that "grub recovery" command-line and experiment a bit... I'm not sure if this has had any point, or if it give you some information (notice, that i don't know what i'm doing :P ) when i've type command: insmod (hd1,1)/boot/grub/linux.mod i've get message: unknown filesystem the same with: insmod (hd1,msdos1)/boot/grub/linux.mod the same with: insmod ext3 but i get no message after command: insmod ext2 ... notice that i really don't know what this command exactly do, but than i thought that maybe if i reinstall ubuntu with ext2 filesystem, it will work. I've done that, but symptoms are the same. I've go back to that Live version of ubuntu, filesystem and basics directories seems to be present on /dev/sdb1 ... i'm completely unfamiliar with GRUB. I'm also don't know which wersion of GRUB it is, i hope there is only one version on ubuntu-12.04-desktop-i386.iso Any help? Thax

• Oracle WebCenter: Composite Applications & Mash-Ups

  - by kellsey.ruppel(at)oracle.com

  We’ve talked in previous weeks about the key goals of the new release of WebCenter are providing a Modern User Experience, unparalleled Application Integration, converging all the best of the existing portal platforms into WebCenter and delivering a Common User Experience Architecture.  We’ve provided an overview of Oracle WebCenter and discussed some of the other key goals in previous weeks, and this week, we’ll focus on how with the new release of Oracle WebCenter you can create composite applications and mashups.We recently talked with Sachin Agarwal, Director of Product Management of Enterprise 2.0 at Oracle around the topic of Composite Applications and Mashups. Oracle WebCenter provides a rich set of tools and capabilities for pulling in content, applications and collaboration functionality from various different sources and weaving them together into what we call Mashups. Mashups that also consists of transactional applications from multiple sources are specifically called Composite Applications. With the latest release of Oracle WebCenter one can develop highly productive tasked based interfaces that aggregate a related set of applications that are part of a business process and provide in context collaboration tools so that users don’t have to navigate away to different tabs to achieve these tasks. For instance, a call center representative (CSR), not only needs to be able to pull customer information from a CRM application like Siebel, but also related information from Oracle E-Business Suite about whether a specific order has shipped. The CSR will be far more efficient if he or she does not have to open different tabs to login into multiple applications while the customer is waiting, but can access all this information in one mashup.Oracle WebCenter Suite provides a comprehensive set of tooling that enables a business user to quickly aggregate together a mashup and wire-in different backend applications to create a custom dashboard. Not only does Oracle WebCenter supports a wide set of standards (WSRP 1.0, 2.0, JSR 168, JSR 286) that allow portlets  from other applications to be surfaced within WebCenter, but it also provides tools to bring in other web applications such as .Net Applications  as well as SharePoint webparts. The new Business Mash-up editor allows business users to take any Oracle Application or 3rd party application and wire the backend data sources or APIs to a rich set of visualizations and reuse them in mashups.  Moreover, Business users can customize or personalize any page using Oracle WebCenter Composer’s on-the-fly visual page editing features. Users access and select different resource components available in Oracle WebCenter’s Business Dictionary in order to add new content to the page. The Business Dictionary provides a role-based view of available components or resources, and these components can include information from a variety of enterprise resources such as enterprise applications, managed content, rich media, business processes, or business intelligence systems. Together, Oracle WebCenter’s Composer and Business Dictionary give users access to a powerful, yet easy to use, set of tools to personalize and extend their Oracle WebCenter portals and applications without involving IT.Keep checking back this week as we share more information on how you can easily create Commposite Applications and Mashups with Oracle WebCenter .Technorati Tags: UXP, collaboration, enterprise 2.0, modern user experience, oracle, portals, webcenter, applications, mashups, composite applications
