Architects Matter: Making sense of the people who make sense of enterprise IT Why do architects matter? Oracle Enterprise Architect Eric Stephens suggests that you ask yourself this question the next time you take the elevator to the Oracle offices on the 45th floor of the Willis Tower in Chicago, Illinois (or any other skyscraper, for that matter). If you had to take the stairs to get to those offices, who would you blame? "You get the picture," he says. "Architecture is essential for any necessarily complex structure, be it a building or an enterprise." (Read the article) Thought for the Day "I will contend that conceptual integrity is the most important consideration in system design. It is better to have a system omit certain anomalous features and improvements, but to reflect one set of design ideas, than to have one that contains many good but independent and uncoordinated ideas." — Frederick P.

• I.T. Chargeback : Core to Cloud Computing

  - by Anand Akela

  Contributed by Mark McGill Consolidation and Virtualization have been widely adopted over the years to help deliver benefits such as increased server utilization, greater agility and lower cost to the I.T. organization. These are key enablers of cloud, but in themselves they do not provide a complete cloud solution. Building a true enterprise private cloud involves moving from an admin driven world, where the I.T. department is ultimately responsible for the provisioning of servers, databases, middleware and applications, to a world where the consumers of I.T. resources can provision their infrastructure, platforms and even complete application stacks on demand. Switching from an admin-driven provisioning model to a user-driven model creates some challenges. How do you ensure that users provisioning resources will not provision more than they need? How do you encourage users to return resources when they have finished with them so that others can use them? While chargeback has existed as a concept for many years (especially in mainframe environments), it is the move to this self-service model that has created a need for a new breed of chargeback applications for cloud. Enabling self-service without some form of chargeback is like opening a shop where all of the goods are free. A successful chargeback solution will be able to allocate the costs of shared I.T. infrastructure based on the relative consumption by the users. Doing this creates transparency between the I.T. department and the consumers of I.T. When users are able to understand how their consumption translates to cost they are much more likely to be prudent when it comes to their use of I.T. resources. This also gives them control of their I.T. costs, as moderate usage will translate to a lower charge at the end of the month. Implementing Chargeback successfully create a win-win situation for I.T. and the consumers. Chargeback can help to ensure that I.T. resources are used for activities that deliver business value. It also improves the overall utilization of I.T. infrastructure as I.T. resources that are not needed are not left running idle. Enterprise Manager 12c provides an integrated metering and chargeback solution for Enterprise Manager Targets. This solution is built on top of the rich configuration and utilization information already available in Enterprise Manager. It provides metering not just for virtual machines, but also for physical hosts, databases and middleware. Enterprise Manager 12c provides metering based on the utilization and configuration of the following types of Enterprise Manager Target: Oracle VM Host Oracle Database Oracle WebLogic Server Using Enterprise Manager Chargeback, administrators are able to create a set of Charge Plans that are used to attach prices to the various metered resources. These plans can contain fixed costs (eg. $10/month/database), configuration based costs (eg. $10/month if OS is Windows) and utilization based costs (eg. $0.05/GB of Memory/hour) The self-service user provisioning these resources is then able to view a report that details their usage and helps them understand how this usage translates into cost. Armed with this information, the user is able to determine if the resources are delivering adequate business value based on what is being charged. Figure 1: Chargeback in Self-Service Portal Enterprise Manager 12c provides a variety of additional interfaces into this data. The administrator can access summary and trending reports. Summary reports allow the administrator to drill-down through the cost center hierarchy to identify, for example, the top resource consumers across the organization. Figure 2: Charge Summary Report Trending reports can be used for I.T. planning and budgeting as they show utilization and charge trends over a period of time. Figure 3: CPU Trend Report We also provide chargeback reports through BI Publisher. This provides a way for users who do not have an Enterprise Manager login (such as Line of Business managers) to view charge and usage information. For situations where a bill needs to be produced, chargeback can be integrated with billing applications such as Oracle Billing and Revenue Management (BRM).

• Linux-Containers — Part 1: Overview

  - by Lenz Grimmer

  "Containers" by Jean-Pierre Martineau (CC BY-NC-SA 2.0). Linux Containers (LXC) provide a means to isolate individual services or applications as well as of a complete Linux operating system from other services running on the same host. To accomplish this, each container gets its own directory structure, network devices, IP addresses and process table. The processes running in other containers or the host system are not visible from inside a container. Additionally, Linux Containers allow for fine granular control of resources like RAM, CPU or disk I/O. Generally speaking, Linux Containers use a completely different approach than "classicial" virtualization technologies like KVM or Xen (on which Oracle VM Server for x86 is based on). An application running inside a container will be executed directly on the operating system kernel of the host system, shielded from all other running processes in a sandbox-like environment. This allows a very direct and fair distribution of CPU and I/O-resources. Linux containers can offer the best possible performance and several possibilities for managing and sharing the resources available. Similar to Containers (or Zones) on Oracle Solaris or FreeBSD jails, the same kernel version runs on the host as well as in the containers; it is not possible to run different Linux kernel versions or other operating systems like Microsoft Windows or Oracle Solaris for x86 inside a container. However, it is possible to run different Linux distribution versions (e.g. Fedora Linux in a container on top of an Oracle Linux host), provided it supports the version of the Linux kernel that runs on the host. This approach has one caveat, though - if any of the containers causes a kernel crash, it will bring down all other containers (and the host system) as well. For example, Oracle's Unbreakable Enterprise Kernel Release 2 (2.6.39) is supported for both Oracle Linux 5 and 6. This makes it possible to run Oracle Linux 5 and 6 container instances on top of an Oracle Linux 6 system. Since Linux Containers are fully implemented on the OS level (the Linux kernel), they can be easily combined with other virtualization technologies. It's certainly possible to set up Linux containers within a virtualized Linux instance that runs inside Oracle VM Server for Oracle VM Virtualbox. Some use cases for Linux Containers include: Consolidation of multiple separate Linux systems on one server: instances of Linux systems that are not performance-critical or only see sporadic use (e.g. a fax or print server or intranet services) do not necessarily need a dedicated server for their operations. These can easily be consolidated to run inside containers on a single server, to preserve energy and rack space. Running multiple instances of an application in parallel, e.g. for different users or customers. Each user receives his "own" application instance, with a defined level of service/performance. This prevents that one user's application could hog the entire system and ensures, that each user only has access to his own data set. It also helps to save main memory — if multiple instances of a same process are running, the Linux kernel can share memory pages that are identical and unchanged across all application instances. This also applies to shared libraries that applications may use, they are generally held in memory once and mapped to multiple processes. Quickly creating sandbox environments for development and testing purposes: containers that have been created and configured once can be archived as templates and can be duplicated (cloned) instantly on demand. After finishing the activity, the clone can safely be discarded. This allows to provide repeatable software builds and test environments, because the system will always be reset to its initial state for each run. Linux Containers also boot significantly faster than "classic" virtual machines, which can save a lot of time when running frequent build or test runs on applications. Safe execution of an individual application: if an application running inside a container has been compromised because of a security vulnerability, the host system and other containers remain unaffected. The potential damage can be minimized, analyzed and resolved directly from the host system. Note: Linux Containers on Oracle Linux 6 with the Unbreakable Enterprise Kernel Release 2 (2.6.39) are still marked as Technology Preview - their use is only recommended for testing and evaluation purposes. The Open-Source project "Linux Containers" (LXC) is driving the development of the technology behind this, which is based on the "Control Groups" (CGroups) and "Name Spaces" functionality of the Linux kernel. Oracle is actively involved in the Linux Containers development and contributes patches to the upstream LXC code base. Control Groups provide means to manage and monitor the allocation of resources for individual processes or process groups. Among other things, you can restrict the maximum amount of memory, CPU cycles as well as the disk and network throughput (in MB/s or IOP/s) that are available for an application. Name Spaces help to isolate process groups from each other, e.g. the visibility of other running processes or the exclusive access to a network device. It's also possible to restrict a process group's access and visibility of the entire file system hierarchy (similar to a classic "chroot" environment). CGroups and Name Spaces provide the foundation on which Linux containers are based on, but they can actually be used independently as well. A more detailed description of how Linux Containers can be created and managed on Oracle Linux will be explained in the second part of this article.

• SQL Developer at Oracle Open World 2012

  - by thatjeffsmith

  We have a lot going on in San Francisco this fall. One of the most personal exciting bits, for what will be my 4th or 5th Open World, is that this will be my FIRST as a member of Team Oracle. I’ve presented once before, but most years it was just me pressing flesh at the vendor booths. After 3-4 days of standing and talking, you’re ready to just go home and not do anything for a few weeks. This time I’ll have a chance to walk around and talk with our users and get a good idea of what’s working and what’s not. Of course it will be a great opportunity for you to find us and get to know your SQL Developer team! 3.4 miles across and back – thanks Ashley for signing me up for the run! This year is going to be a bit crazy. Work wise I’ll be presenting twice, working a booth, and proctoring several of our Hands-On Labs. The fun parts will be equally crazy though – running across the Bay Bridge (I don’t run), swimming the Bay (I don’t swim), having my wife fly out on Wednesday for the concert, and then our first WhiskyFest on Friday (I do drink whisky though.) But back to work – let’s talk about EVERYTHING you can expect from the SQL Developer team. Booth Hours We’ll have 2 ‘demo pods’ in the Exhibition Hall over at Moscone South. Look for the farm of Oracle booths, we’ll be there under the signs that say ‘SQL Developer.’ There will be several people on hand, mostly developers (yes, they still count as people), who can answer your questions or demo the latest features. Come by and say ‘Hi!’, and let us know what you like and what you think we can do better. Seriously. Monday 10AM – 6PM Tuesday 9:45AM – 6PM Wednesday 9:45AM – 4PM Presentations Stop by for an hour, pull up a chair, sit back and soak in all the SQL Developer goodness. You’ll only have to suffer my bad jokes for two of the presentations, so please at least try to come to the other ones. We’ll be talking about data modeling, migrations, source control, and new features in versions 3.1 and 3.2 of SQL Developer and SQL Developer Data Modeler. Day Time Event Monday 10:454:45 What’s New in SQL Developer Why Move to Oracle Application Express Listener Tueday 10:1511:455:00 Using Subversion in Oracle SQL Developer Data Modeler Oracle SQL Developer Tips & Tricks Database Design with Oracle SQL Developer Data Modeler Wednesday 11:453:30 Migrating Third-Party Databases and Applications to Oracle Exadata 11g Enterprise Options and Management Packs for Developers Hands On Labs (HOLs) The Hands On Labs allow you to come into a classroom environment, sit down at a computer, and run through some exercises. We’ll provide the hardware, software, and training materials. It’s self-paced, but we’ll have several helpers walking around to answer questions and chat up any SQL Developer or database topic that comes to mind. If your employer is sending you to Open World for all that great training, the HOLs are a great opportunity to capitalize on that. They are only 60 minutes each, so you don’t have to worry about burning out. And there’s no homework! Of course, if you do want to take the labs home with you, many are already available via the Developer Day Hands-On Database Applications Developer Lab. You will need your own computer for those, but we’ll take care of the rest. Wednesday PL/SQL Development and Unit Testing with Oracle SQL Developer 10:15 Performance Tuning with Oracle SQL Developer 11:45 Thursday The Soup to Nuts of Data Modeling with Oracle SQL Developer Data Modeler 11:15 Some Parting Advice Always wanted to meet your favorite Oracle authors, speakers, and thought-leaders? Don’t be shy, walk right up to them and introduce yourself. Normal social rules still apply, but at the conference everyone is open and up for meeting and talking with attendees. Just understand if there’s a line that you might only get a minute or two. It’s a LONG conference though, so you’ll have plenty of time to catch up with everyone. If you’re going to be around on Tuesday evening, head on over to the OTN Lounge from 4:30 to 6:30 and hang out for our Tweet Meet. That’s right, all the Oracle nerds on Twitter will be there in one place. Be sure to put your Twitter handle on your name tag so we know who you are!

• How to Collect Debug Info for Oracle SQL Developer

  - by thatjeffsmith

  In a perfect world, there would be no software bugs. Developers would always test their code. QA would find any scenarios and bugs the developers hadn’t already thought of. Regression tests would be complete and flawless. But alas, we can only afford to pay mere humans here, so we will have bugs from time to time. Or sometimes you are trying to do something the software wasn’t designed for, or perhaps your machine has exhausted it’s resources trying to build the un-buildable. When you run into problems, you will need help. Developers need your help so they can help you. Surprisingly enough, feedback like this isn’t very helpful: Your program isn’t working. How can I make it work? When you are ready to work with us on the SQL Developer OTN forum, you will most likely be asked to run SQL Developer and capture the output from the command console. In case you need help with this, ere’s a step-by-step process you can follow in Windows 7 (should work in XP too.) Open a windows command window Start – Run – CMD Once it’s open, click on the window icon and select ‘Defaults.’ Change the default buffer size to be something bigger, much bigger. Set the CMD window default buffer size HIGHER Note: you only need to do this once. Navigate to your SQL Developer Installation Folder Instead of running the ‘sqldeveloper.exe’ file in the root directory, we are going to go several sub-directories down. Find the ‘bin’ sub-directory and run the ‘sqldeveloper.exe’ there. When you do this, a CMD window will open, and then you’ll see the SQL Developer application load. The SQL Developer bin directory - run the tool from here and get a logging window Use SQL Developer as normal, until it ‘breaks’ or ‘hangs’ Now, you are ready to grab the nitty-gritty information that MIGHT tell the developer what is going wrong or happening in your scenario. Click back into the CMD window Send a Ctrl+Break or a Ctrl+Pause. If you on a newer laptop that doesn’t have this key, be sure to check the ‘Fn’ subset of keys. If you need to map the BREAK or PAUSE buttons, this article might help. You can also try the on-screen keyboard in windows – just type ‘OSK’ in your START – RUN prompt. Copy the logging information from the command window – all of it We need this information, help us get it! Open a case with Oracle Support or Start a Thread on the Forums Or email me. If you’re on my blog reading this, it’s the least I can do to help Now, before you hit ‘Send’ or ‘Post’ or ‘Submit’ – be sure to add a brief description of what you were doing in the application when you ran into the problem. Even if you were doing ‘nothing,’ let us know how many connections you had open, what windows were active, etc. The more you can tell us, the higher your odds go up to getting a quick fix or at least an answer as to what is happening. Also include the following information: The version of SQL Developer you are running The version of the JDK you are using The OS you are using The version of Oracle you are connected to Now, don’t be surprised if you get asked to upgrade to a supported configuration, say ‘version 3.1 and the 1.6 JDK.’ Supporting older versions of software is fun, and while we enjoy a challenge, it may be easier for you to upgrade your way out of the problem at hand.

The value lookup can be configured to be displayed as a select list, combo box, input list of values or combo box with list of values. Displaying the list in an af:inputListOfValues component shows the attribute value in an input text field and with an icon attached to it for the user to launch the list-of-values dialog. The list-of-values dialog allows users to use a search form to filter the lookup data list and to select an entry, which return value then is added as the value of the af:inputListOfValues component. Note: The model driven LOV can be configured in ADF Business Components to update multiple attributes with the user selection, though the most common use case is to update the value of a single attribute. A question on OTN was how to access the row of the selected return value on the ADF Faces front end. For this, you need to know that there is a Model property defined on the af:inputListOfValues that references the ListOfValuesModel implementation in the model. It is the value of this Model property that you need to get access to. The af:inputListOfValues has a ReturnPopupListener property that you can use to configure a managed bean method to receive notification when the user closes the LOV popup dialog by selecting the Ok button. This listener is not triggered when the cancel button is pressed. The managed bean signature can be created declaratively in Oracle JDeveloper 11g using the Edit option in the context menu next to the ReturnPopupListener field in the PropertyInspector. The empty method signature looks as shown below public void returnListener(ReturnPopupEvent returnPopupEvent) { } The ReturnPopupEvent object gives you access the RichInputListOfValues component instance, which represents the af:inputListOfValues component at runtime. From here you access the Model property of the component to then get a handle to the CollectionModel. The CollectionModel returns an instance of JUCtrlHierBinding in its getWrappedData method. Though there is no tree binding definition for the list of values dialog defined in the PageDef, it exists. Once you have access to this, you can read the row the user selected in the list of values dialog. See the following code: public void returnListener(ReturnPopupEvent returnPopupEvent) {   //access UI component instance from return event RichInputListOfValues lovField =        (RichInputListOfValues)returnPopupEvent.getSource();   //The LOVModel gives us access to the Collection Model and //ADF tree binding used to populate the lookup table ListOfValuesModel lovModel =  lovField.getModel(); CollectionModel collectionModel =          lovModel.getTableModel().getCollectionModel();     //The collection model wraps an instance of the ADF //FacesCtrlHierBinding, which is casted to JUCtrlHierBinding   JUCtrlHierBinding treeBinding =          (JUCtrlHierBinding) collectionModel.getWrappedData();     //the selected rows are defined in a RowKeySet.As the LOV table only   //supports single selections, there is only one entry in the rks RowKeySet rks = (RowKeySet) returnPopupEvent.getReturnValue();     //the ADF Faces table row key is a list. The list contains the //oracle.jbo.Key List tableRowKey = (List) rks.iterator().next();   //get the iterator binding for the LOV lookup table binding   DCIteratorBinding dciter = treeBinding.getDCIteratorBinding();   //get the selected row by its JBO key   Key key = (Key) tableRowKey.get(0); Row rw =  dciter.findRowByKeyString(key.toStringFormat(true)); //work with the row // ... }

• I Didn&rsquo;t Get You Anything&hellip;

  - by Bob Rhubart

  Nearly every day this blog features a  list posts and articles written by members of the OTN architect community. But with Christmas just days away, I thought a break in that routine was in order. After all, if the holidays aren’t excuse enough for an off-topic post, then the terrorists have won. Rather than buy gifts for everyone -- which, given the readership of this blog and my budget could amount to a cash outlay of upwards of $15.00 – I thought I’d share a bit of holiday humor. I wrote the following essay back in the mid-90s, for a “print” publication that used “paper” as a content delivery system.  That was then. I’m older now, my kids are older, but my feelings toward the holidays haven’t changed… It’s New, It’s Improved, It’s Christmas! The holidays are a time of rituals. Some of these, like the shopping, the music, the decorations, and the food, are comforting in their predictability. Other rituals, like the shopping, the  music, the decorations, and the food, can leave you curled into the fetal position in some dark corner, whimpering. How you react to these various rituals depends a lot on your general disposition and credit card balance. I, for one, love Christmas. But there is one Christmas ritual that really tangles my tinsel: the seasonal editorializing about how our modern celebration of the holidays pales in comparison to that of Christmas past. It's not that the old notions of how to celebrate the holidays aren't all cozy and romantic--you can't watch marathon broadcasts of "It's A Wonderful White Christmas Carol On Thirty-Fourth Street Story" without a nostalgic teardrop or two falling onto your plate of Christmas nachos. It's just that the loudest cheerleaders for "old-fashioned" holiday celebrations overlook the fact that way-back-when those people didn't have the option of doing it any other way. Dashing through the snow in a one-horse open sleigh? No thanks. When Christmas morning rolls around, I'm going to be mighty grateful that the family is going to hop into a nice warm Toyota for the ride over to grandma's place. I figure a horse-drawn sleigh is big fun for maybe fifteen minutes. After that you’re going to want Old Dobbin to haul ass back to someplace warm where the egg nog is spiked and the family can gather in the flickering glow of a giant TV and contemplate the true meaning of football. Chestnuts roasting on an open fire? Sorry, no fireplace. We've got a furnace for heat, and stuffing nuts in there voids the warranty. Any of the roasting we do these days is in the microwave, and I'm pretty sure that if you put chestnuts in the microwave they would become little yuletide hand grenades. Although, if you've got a snoot full of Yule grog, watching chestnuts explode in your microwave might be a real holiday hoot. Some people may see microwave ovens as a symptom of creeping non-traditional holiday-ism. But I'll bet you that if there were microwave ovens around in Charles Dickens' day, the Cratchits wouldn't have had to entertain an uncharacteristically giddy Scrooge for six or seven hours while the goose cooked. Holiday entertaining is, in fact, the one area that even the most severe critic of modern practices would have to admit has not changed since Tim was Tiny. A good holiday celebration, then as now, involves lots of food, free-flowing drink, and a gathering of friends and family, some of whom you are about as happy to see as a subpoena. Just as the Cratchit's Christmas was spent with a man who, for all they knew, had suffered some kind of head trauma, so the modern holiday gathering includes relatives or acquaintances who, because they watch too many talk shows, and/or have poor personal hygiene, and/or fail to maintain scheduled medication, you would normally avoid like a plate of frosted botulism. But in the season of good will towards men, you smile warmly at the mystery uncle wandering around half-crocked with a clump of mistletoe dangling from the bill of his N.R.A. cap. Dickens' story wouldn't have become the holiday classic it has if, having spotted on their doorstep an insanely grinning, raw poultry-bearing, fresh-off-a-rough-night Scrooge, the Cratchits had pulled their shades and pretended not to be home. Which is probably what I would have done. Instead, knowing full well his reputation as a career grouch, they welcomed him into their home, and we have a touching story that teaches a valuable lesson about how the Christmas spirit can get the boss to pump up the payroll. Despite what the critics might say, our modern Christmas isn't all that different from those of long ago. Sure, the technology has changed, but that just means a bigger, brighter, louder Christmas, with lasers and holograms and stuff. It's our modern celebration of a season that even the least spiritual among us recognizes as a time of hope that the nutcases of the world will wake up and realize that peace on earth is a win/win proposition for everybody. If Christmas has changed, it's for the better. We should continue making Christmas bigger and louder and shinier until everybody gets it.  *** Happy Holidays, everyone!   del.icio.us Tags: holiday,humor Technorati Tags: holiday,humor

As one would expect of an industry leader, Oracle's participation in industry standards bodies is extensive. We participate in dozens of organizations that produce open standards which apply to our products, and our commitment to the success of these organizations is manifest in several way - we support them financially through our memberships; our senior engineers are active participants, often serving in leadership positions on boards, technical working groups and committees; and when it makes good business sense we contribute our intellectual property. We believe supporting the development of open standards is fundamental to Oracle meeting customer demands for product choice, seamless interoperability, and lowering the cost of ownership. Nowhere is this truer than in the area of cloud standards, and for the most recent release of our flagship management product, Oracle Enterprise Manager Cloud Control 12c (EM Cloud Control 12c). There is a fundamental rule that standards follow architecture. This was true of distributed computing, it was true of service-oriented architecture (SOA), and it's true of cloud. If you are familiar with Enterprise Manager it is likely to be no surprise that EM Cloud Control 12c is a source of technology that can be considered for adoption within cloud management standards. The reason, quite simply, is that the Oracle integrated stack architecture aligns with the cloud architecture models being adopted by the industry, and EM Cloud Control 12c has been developed to manage this architecture. EM Cloud Control 12c has facilities for managing the various underlying capabilities of the integrated stack in IaaS, PaaS, and SaaS clouds, and enables essential characteristics such as on-demand self-service provisioning, centralized policy-based resource management, integrated chargeback, and capacity planning, and complete visibility of the physical and virtual environment from applications to disk. Our most recent contribution in support of cloud management standards to come out of the EM Cloud Control 12c work was the Oracle Cloud Elemental Resource Model API. Oracle contributed the Elemental Resource Model API to the Distributed Management Task Force (DMTF) in 2011 where it was assigned to DMTF's Cloud Management Working Group (CMWG). The CMWG is considering the Oracle specification and those of several other vendors in their effort to produce a best practices specification for managing IaaS clouds. DMTF's Cloud Infrastructure Management Interface specification, called CIMI for short, is currently out for public review and expected to be released by DMTF later this year. We are proud to be playing an important role in the development of what is expected to become a major cloud standard. You can find more information on DMTF CIMI at http://dmtf.org/standards/cloud. You can find the work-in-progress release of CIMI at http://dmtf.org/content/cimi-work-progress-specifications-now-available-public-comment . The Oracle Cloud API specification is available on the Oracle Technology Network. You can find more information about the Oracle Cloud Elemental Resource Model API on the Oracle Technical Network (OTN), including a webcast featuring the API engineering manager Jack Yu (see TechCast Live: Inside the Oracle Cloud Resource Model API). If you have not seen this video we recommend you take the time to view it. Simply hover your cursor over the webcast title and control+click to follow the embedded link. If you have a question about the Oracle Cloud API or want to learn more about Oracle's participation in cloud management standards efforts drop us a line. We'd love to hear from you.

• Talking JavaOne with Rock Star Martijn Verburg

  - by Janice J. Heiss

  JavaOne Rock Stars, conceived in 2005, are the top-rated speakers at each JavaOne Conference. They are awarded by their peers, who, through conference surveys, recognize them for their outstanding sessions and speaking ability. Over the years many of the world’s leading Java developers have been so recognized. Martijn Verburg has, in recent years, established himself as an important mover and shaker in the Java community. His “Diabolical Developer” session at the JavaOne 2011 Conference got people’s attention by identifying some of the worst practices Java developers are prone to engage in. Among other things, he is co-leader and organizer of the thriving London Java User Group (JUG) which has more than 2,500 members, co-represents the London JUG on the Executive Committee of the Java Community Process, and leads the global effort for the Java User Group “Adopt a JSR” and “Adopt OpenJDK” programs. Career highlights include overhauling technology stacks and SDLC practices at Mizuho International, mentoring Oracle on technical community management, and running off shore development teams for AIG. He is currently CTO at jClarity, a start-up focusing on automating optimization for Java/JVM related technologies, and Product Advisor at ZeroTurnaround. He co-authored, with Ben Evans, "The Well-Grounded Java Developer" published by Manning and, as a leading authority on technical team optimization, he is in high demand at major software conferences.Verburg is participating in five sessions, a busy man indeed. Here they are: CON6152 - Modern Software Development Antipatterns (with Ben Evans) UGF10434 - JCP and OpenJDK: Using the JUGs’ “Adopt” Programs in Your Group (with Csaba Toth) BOF4047 - OpenJDK Building and Testing: Case Study—Java User Group OpenJDK Bugathon (with Ben Evans and Cecilia Borg) BOF6283 - 101 Ways to Improve Java: Why Developer Participation Matters (with Bruno Souza and Heather Vancura-Chilson) HOL6500 - Finding and Solving Java Deadlocks (with Heinz Kabutz, Kirk Pepperdine, Ellen Kraffmiller and Henri Tremblay) When I asked Verburg about the biggest mistakes Java developers tend to make, he listed three: A lack of communication -- Software development is far more a social activity than a technical one; most projects fail because of communication issues and social dynamics, not because of a bad technical decision. Sadly, many developers never learn this lesson. No source control -- Developers simply storing code in local filesystems and emailing code in order to integrate Design-driven Design -- The need for some developers to cram every design pattern from the Gang of Four (GoF) book into their source code All of which raises the question: If these practices are so bad, why do developers engage in them? “I've seen a wide gamut of reasons,” said Verburg, who lists them as: * They were never taught at high school/university that their bad habits were harmful.* They weren't mentored in their first professional roles.* They've lost passion for their craft.* They're being deliberately malicious!* They think software development is a technical activity and not a social one.* They think that they'll be able to tidy it up later.A couple of key confusions and misconceptions beset Java developers, according to Verburg. “With Java and the JVM in particular I've seen a couple of trends,” he remarked. “One is that developers think that the JVM is a magic box that will clean up their memory, make their code run fast, as well as make them cups of coffee. The JVM does help in a lot of cases, but bad code can and will still lead to terrible results! The other trend is to try and force Java (the language) to do something it's not very good at, such as rapid web development. So you get a proliferation of overly complex frameworks, libraries and techniques trying to get around the fact that Java is a monolithic, statically typed, compiled, OO environment. It's not a Golden Hammer!”I asked him about the keys to running a good Java User Group. “You need to have a ‘Why,’” he observed. “Many user groups know what they do (typically, events) and how they do it (the logistics), but what really drives users to join your group and to stay is to give them a purpose. For example, within the LJC we constantly talk about the ‘Why,’ which in our case is several whys:* Re-ignite the passion that developers have for their craft* Raise the bar of Java developers in London* We want developers to have a voice in deciding the future of Java* We want to inspire the next generation of tech leaders* To bring the disparate tech groups in London together* So we could learn from each other* We believe that the Java ecosystem forms a cornerstone of our society today -- we want to protect that for the futureLooking ahead to Java 8 Verburg expressed excitement about Lambdas. “I cannot wait for Lambdas,” he enthused. “Brian Goetz and his group are doing a great job, especially given some of the backwards compatibility that they have to maintain. It's going to remove a lot of boiler plate and yet maintain readability, plus enable massive scaling.”Check out Martijn Verburg at JavaOne if you get a chance, and, stay tuned for a longer interview yours truly did with Martijn to be publish on otn/java some time after JavaOne.

• Adding UCM as a search source in Windows Explorer

  - by kyle.hatlestad

  A customer recently pointed out to me that Windows 7 supports federated search within Windows Explorer. This means you can perform searches to external sources such as Google, Flickr, YouTube, etc right from within Explorer. While we do have the Desktop Integration Suite which offers searching within Explorer, I thought it would be interesting to look into this method which would not require any client software to implement. Basically, federated searching hooks up in Windows Explorer through the OpenSearch protocol. A Search Connector Descriptor file is run and it installs the search provider. The file is a .osdx file which is an OpenSearch Description document. It describes the search provider you are hooking up to along with the URL for the query. If those results can come back as an RSS or ATOM feed, then you're all set. So the first step is to install the RSS Feeds component from the UCM Samples page on OTN. If you're on 11g, I've found the RSS Feeds works just fine on that version too. Next, you want to perform a Quick Search with a particular search term and then copy the RSS link address for that search result. Here is what an example URL might looks like: http://server:16200/cs/idcplg?IdcService=GET_SCS_FEED&feedName=search_results&QueryText=%28+%3cqsch%3eoracle%3c%2fqsch %3e+%29&SortField=dInDate&SortOrder=Desc&ResultCount=20&SearchQueryFormat= Universal&SearchProviders=server& Now you want to create a new text file and start out with this information: <?xml version="1.0" encoding="UTF-8"?><OpenSearchDescription xmlns:ms-ose="http://schemas.microsoft.com/opensearchext/2009/"> <ShortName></ShortName> <Description></Description> <Url type="application/rss+xml" template=""/> <Url type="text/html" template=""/> </OpenSearchDescription> Enter a ShortName and Description. The ShortName will be the value used when displaying the search provider in Explorer. In the template attribute for the first Url element, enter the URL copied previously. You will then need to convert the ampersand symbols to '&' to make them XML compliant. Finally, you'll want to switch out the search term with '{searchTerms}'. For the second Url element, you can do the same thing except you want to copy the UCM search results URL from the page of results. That URL will look something like: http://server:16200/cs/idcplg?IdcService=GET_SEARCH_RESULTS&SortField=dInDate&SortOrder=Desc&ResultCount=20&QueryText=%3Cqsch%3Eoracle%3C%2Fqsch%3E&listTemplateId= &ftx=1&SearchQueryFormat=Universal&TargetedQuickSearchSelection= &MiniSearchText=oracle Again, convert the ampersand symbols and replace the search term with '{searchTerms}'. When complete, save the file with the .osdx extension. The completed file should look like: <?xml version="1.0" encoding="UTF-8"?> <OpenSearchDescription xmlns="http://a9.com/-/spec/opensearch/1.1/" xmlns:ms-ose="http://schemas.microsoft.com/opensearchext/2009/"> <ShortName>Universal Content Management</ShortName> <Description>OpenSearch for UCM via Windows 7 Search Federation.</Description> <Url type="application/rss+xml" template="http://server:16200/cs/idcplg?IdcService=GET_SCS_FEED&amp;feedName=search_results&amp;QueryText=%28+%3Cqsch%3E{searchTerms}%3C%2fqsch%3E+%29&amp;SortField=dInDate&amp;SortOrder=Desc&amp;ResultCount=200&amp;SearchQueryFormat=Universal"/> <Url type="text/html" template="http://server:16200/cs/idcplg?IdcService=GET_SEARCH_RESULTS&amp;SortField=dInDate&amp;SortOrder=Desc&amp;ResultCount=20&amp;QueryText=%3Cqsch%3E{searchTerms}%3C%2Fqsch%3E&amp;listTemplateId=&amp;ftx=1&amp;SearchQueryFormat=Universal&amp;TargetedQuickSearchSelection=&amp;MiniSearchText={searchTerms}"/> </OpenSearchDescription> After you save the file, simply double-click it to create the provider. It will ask if you want to add the search connector to Windows. Click Add and it will add it to the Searches folder in your user folder as well as your Favorites. Now just click on the search icon and in the upper right search box, enter your term. As you are typing, it begins executing searches and the results will come back in Explorer. Now when you double-click on an item, it will try and download the web viewable for viewing. You also have the ability to save the search, just as you would in UCM. And there is a link to Search On Website which will launch your browser and go directly to the search results page there. And with some tweaks to the RSS component, you can make the results a bit more interesting. It supports the Media RSS standard, so you can pass along the thumbnail of the documents in the results. To enable this, edit the rss_resources.htm file in the RSS Feeds component. In the std_rss_feed_begin resource include, add the namespace 'xmlns:media="http://search.yahoo.com/mrss/' to the rss definition: <rss version="2.0" xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:sy="http://purl.org/rss/1.0/modules/syndication/" xmlns:media="http://search.yahoo.com/mrss/"> Next, in the rss_channel_item_with_thumb include, below the closing image element, add this element: </images> <media:thumbnail url="<$if strIndexOf(thumbnailUrl, "@t") > 0 or strIndexOf(thumbnailUrl, "@g") > 0 or strIndexOf(thumbnailUrl, "@p") > 0$><$rssHttpHost$><$thumbnailUrl$><$elseif dGif$><$HttpWebRoot$>images/docgifs/<$dGif$><$endif$>" /> <description> This and lots of other tweaks can be done to the RSS component to help extend it for optimum use in Explorer. Hopefully this can get you started. *Note: This post also applies to Universal Records Management (URM).

• Back Up to Tape the Way You Shop For Groceries

  - by rickramsey

  Imagine if this was how you shopped for groceries: From the end of the aisle sprint to the point where you reach the ketchup. Pull a bottle from the shelf and yell at the top of your lungs, “Got it!” Sprint back to the end of the aisle. Start again and sprint down the same aisle to the mustard, pull a bottle from the shelf and again yell for the whole store to hear, “Got it!” Sprint back to the end of the aisle. Repeat this procedure for every item you need in the aisle. Proceed to the next aisle and follow the same steps for the list of items you need from that aisle. Sounds ridiculous, doesn’t it? Not only is it horribly inefficient, it’s exhausting and can lead to wear out failures on your grocery cart, or worse, yourself. This is essentially how NetApp and some other applications write NDMP backups to tape. In the analogy, the ketchup and mustard are the files to be written, yelling “Got it!” is the equivalent of a sync mark at the end of a file, and the sprint back to the end of an aisle is the process most commonly called a “backhitch” where the drive has to back up on a tape to start writing again. Writing to tape in this way results in very slow tape drive performance and imposes unnecessary wear on the tape drive and the media, especially when writing small files. The good news is not all tape drives behave this way when writing small files. Unlike midrange LTO drives, Oracle’s StorageTek T10000D tape drive is designed to handle this scenario efficiently. The difference between the two drive types is that the T10000D drive gives you the ability to write files in a NetApp NDMP backup environment the way you would normally shop for groceries. With grocery shopping, you essentially stream through aisles picking up items as you go, and then after checking out, yell, “Got it!”, though you might do that last step silently. With the T10000D, it has a feature called the Tape Application Accelerator, which prevents the drive from having to stop after each file is written to notify NetApp or another application that the write was successful. When enabled in the T10000D tape drive, Tape Application Accelerator causes the tape drive to respond to tape mark and file sync commands differently than when disabled: A tape mark received by the tape drive is treated as a buffered tape mark. A file sync received by the tape drive is treated as a no op command. Since buffered tape marks and no op commands do not cause the tape drive to empty the contents of its buffer to tape and backhitch, the data is written to tape in significantly less time. Oracle has emulated NetApp environments with a number of different file sizes and found the following when comparing the T10000D with the Tape Application Accelerator enabled versus LTO6 tape drives. Notice how the T10000D is not only monumentally faster, but also remarkably consistent? In addition, the writing of the 50 GB of files is done without a single backhitch. The LTO6 drive, meanwhile, will perform as many as 3,800 backhitches! At the end of writing the entire set of files, the T10000D tape drive reports back to the application, in this case NetApp, that the write was successful via a tape mark. So if the Tape Application Accelerator dramatically improves performance and reliability, why wouldn’t you always have it enabled? The reason is because tape drive buffers are meant to be just temporary data repositories so in the event of a power loss, there could be data loss in certain environments for the files that resided in the buffer. Fortunately, we do have best practices depending on your environment to avoid this from happening. I highly recommend reading Maximizing Tape Performance with StorageTek T10000 Tape Drives (pdf) to decide which best practice is right for you. The white paper also digs deeper into the benefits of the Tape Application Accelerator. The white paper is free, and after downloading it you can decide for yourself whether you want to yell “Got it!” out loud or just silently to yourself. Customer Advisory Panel One final link: Oracle has started up a Customer Advisory Panel program to collect feedback from customers on their current experiences with Oracle products, as well as desires for future product development.

• BPM Suite 11gR1 Released

  - by Manoj Das

  This morning (April 27th, 2010), Oracle BPM Suite 11gR1 became available for download from OTN and eDelivery. If you have been following our plans in this area, you know that this is the release unifying BEA ALBPM product, which became Oracle BPM10gR3, with the Oracle stack. Some of the highlights of this release are: BPMN 2.0 modeling and simulation Web based Process Composer for BPMN and Rules authoring Zero-code environment with full access to Oracle SOA Suite’s rich set of application and other adapters Process Spaces – Out-of-box integration with Web Center Suite Process Analytics – Native process cubes as well as integration with Oracle BAM You can learn more about this release from the documentation. Notes about downloading and installing Please note that Oracle BPM Suite 11gR1 is delivered and installed as part of SOA 11.1.1.3.0, which is a sparse release (only incremental patch). To install: Download and install SOA 11.1.1.2.0, which is a full release (you can find the bits at the above location) Download and install SOA 11.1.1.3.0 During configure step (using the Fusion Middleware configuration wizard), use the Oracle Business Process Management template supplied with the SOA Suite11g (11.1.1.3.0) If you plan to use Process Spaces, also install Web Center 11.1.1.3.0, which also is delivered as a sparse release and needs to be installed on top of Web Center 11.1.1.2.0 Some early feedback We have been receiving very encouraging feedback on this release. Some quotes from partners are included below: “I just attended a preview workshop on BPM Studio, Oracle's BPMN 2.0 tool, held by Clemens Utschig Utschig from Oracle HQ. The usability and ease to get started are impressive. In the business view analysts can intuitively start modeling, then developers refine in their own, more technical view. The BPM Studio sets itself apart from pure play BPMN 2.0 tools by being seamlessly integrated inside a holistic SOA / BPM toolset: BPMN models are placed in SCA-Composites in SOA Suite 11g. This allows to abstract away the complexities of SOA integration aspects from business process aspects. For UIs in BPMN tasks, you have the richness of ADF 11g based Frontends. With BPM Studio we architects have a new modeling and development IDE that gives us interesting design challenges to grasp and elaborate, since many things BPMN 2.0 are different from good ol' BPEL. For example, for simple transformations, you don't use BPEL "assign" any more, but add the transformation directly to the service call. There is much less XPath involved. And, there is no translation from model to BPEL code anymore, so the awkward process model to BPEL roundtrip, which never really worked as well as it looked on marketing slides, is obsolete: With BPMN 2.0 "the model is the code". Now, these are great times to start the journey into BPM! Some tips: Start Projects smoothly, with initial processes being not overly complex and not using the more esoteric areas of BPMN, to manage the learning path and to stay successful with each iteration. Verify non functional requirements by conducting performance and load tests early. As mentioned above, separate all technical integration logic into SOA Suite or Oracle Service Bus. And - share your experience!” Hajo Normann, SOA Architect - Oracle ACE Director - Co-Leader DOAG SIG SOA   "Reuse of components across the Oracle 11G Fusion Middleware stack, like for instance a Database Adapter, is essential. It improves stability and predictability of the solution. BPM just is one of the components plugging into the stack and reuses all other components." Mr. Leon Smiers, Oracle Solution Architect, Capgemini   “I had the opportunity to follow a hands-on workshop held by Clemens for Oracle partners and I was really impressed of the overall offering of BPM11g. BPM11g allows the execution of BPMN 2.0 processes, without having to transform/translate them first to BPEL in order to be executable. The fact that BPMN uses the same underlying service infrastructure of SOA Suite 11g has a lot of benefits for us already familiar with SOA Suite 11g. BPMN is just another SCA component within a SCA composite and can (re)use all the existing components like Rules, Human Workflow, Adapters and Mediator. I also like the fact that BPMN runs on the same service engine as BPEL. By that all known best practices for making a BPEL  process reliable are valid for BPMN processes as well. Last but not least, BPMN is integrated into the superior end-to-end tracing of SOA Suite 11g. With BPM11g, Oracle offers a very competitive product which will have a big effect on the IT market. Clemens and Jürgen: Thanks for the great workshop! I’m really looking forward to my first project using Oracle BPM11g!” Guido Schmutz, Technology Manager / Oracle ACE Director for Fusion Middleware and SOA, Company:  Trivadis Some earlier feedback were summarized in this post.

• How-to filter table filter input to only allow numeric input

  - by frank.nimphius

  In a previous ADF Code Corner post, I explained how to change the table filter behavior by intercepting the query condition in a query filter. See sample #30 at http://www.oracle.com/technetwork/developer-tools/adf/learnmore/index-101235.html In this OTN Harvest post I explain how to prevent users from providing invalid character entries as table filter criteria to avoid problems upon re-querying the table. In the example shown next, only numeric values are allowed for a table column filter. To create a table that allows data filtering, drag a View Object – or a data collection of a Web Service or JPA business service – from the DataControls panel and drop it as a table. Choose the Enable Filtering option in the Edit Table Columns dialog so the table renders with the column filter boxes displayed. The table filter fields are created using implicit af:inputText components that need to be customized for you to apply a custom filter input component, or to change the input behavior. To change the input filter, so only a defined set of input keys is allowed, you need to change the default filter field with your own af:inputText field to which you apply an af:clientListener tag that filters user keyboard entries. For this, in the Oracle JDeveloper visual editor, select the column which filter you want to change and expand the column node in the Oracle JDeveloper Structure Window. Part of the column definition is the Column facet node. Expand the facets so you see the filter facet entry. The filter facet is grayed out as there is no custom facet defined. In a next step, open theComponent Palette (ctrl+shift+P) and drag an Input Text component onto the facet. This demarks the first part in the filter customization. To make the custom filter component work, you need to map the af:inputText component value property to the ADF filter criteria that is exposed in the Expression Builder. Open the Expression Builder for the filter input component value property by clicking the arrow icon to its right. In the Expression Builder expand the JSP Objects | vs | filterCriteria node to select the attribute name represented by the table column. The vs entry is the name of a variable that is defined on the table and that grants you access to the table attributes. Now that the filter works as before – though using a custom filter input component – you can add the af:clientListener tag to your custom filter component – af:inputText – to call out to JavaScript when users type in the column filter field Point the client filter method property to a JavaScript function that you reference or add through using the af:resource tag and set the type property value to keyDown. <af:document id="d1">     <af:resource type="javascript" source="/js/filterHandler.js"/> … The filter definition looks as shown below <af:inputText label="Label 1" id="it1"                         value="#{vs.filterCriteria.Employe        <af:clientListener method="suppressCharacterInput"                                     type="keyDown"/> </af:inputText> The JavaScript code that you can use to either filter character inputs or numeric inputs is shown below. Just store this code in an external JavaScript (.js) file and reference it from the af:resource tag. //Allow numbers, cursor control keys and delete keys function suppressCharacterInput(evt) {     var _keyCode = evt.getKeyCode();     var _filterField = evt.getCurrentTarget();     var _oldValue = _filterField.getValue();     if (!((_keyCode < 57) ||(_keyCode > 96 && _keyCode < 105))) {         _filterField.setValue(_oldValue);         evt.cancel();     } } //Allow characters, cursor control keys and delete keys function suppressNumericInput(evt) {  var _keyCode = evt.getKeyCode();  var _filterField = evt.getCurrentTarget();  var _oldValue = _filterField.getValue();  //check for numbers  if ((_keyCode < 57 && _keyCode > 47) ||      (_keyCode > 96 && _keyCode < 105)){     _filterField.setValue(_oldValue);     evt.cancel();   } } But what if browsers don't allow JavaScript ? Don't worry about this. If browsers would not support JavaScript then ADF Faces as a whole would not work and you had a different problem.

• Oracle Social Network Developer Challenge Winners

  - by kellsey.ruppel

  Originally posted by Jake Kuramoto on The Apps Lab blog. Now that OpenWorld 2012 has wrapped, I have time to tell you all about what happened. Maybe you recall that Noel (@noelportugal) and I were running a modified hackathon during the show, the Oracle Social Network Developer Challenge. Without further ado, congratulations to Dimitri Gielis (@dgielis) and Martin Giffy D’Souza (@martindsouza) on their winning entry, an integration between Oracle APEX and Oracle Social Network that integrates feedback and bug submission with Oracle Social Network Conversations, allowing developers, end-users and project leaders to view and discuss the feedback on their APEX applications from within Oracle Social Network. Update: Bob Rhubart of OTN (@brhubart) interviewed Dimitri and Martin right after their big win. Money quote from Dimitri when asked what he’d buy with the $500 in Amazon gift cards, “Oracle Social Network.” Nice one. In their own words: In the developers perspective it’s important to get feedback soon, so after a first iteration and end-users start to test, they can give feedback of the application. Previously it stopped there, and it was up to the developer to communicate further with email, phone etc. With OSN every feedback and communication gets logged and other people can see the discussion immediately as well. For the end users perspective he can now communicate in a more efficient way to not only the developers, but also between themselves. Maybe many end-users (in different locations) would like to change some behaviour, by using OSN they can see the entry somebody put in with a screenshot and they can just start to chat about it. Some key technical end users can have lighten the tasks of the development team by looking at the feedback first and start to communicate with their peers. For the project manager he has now the ability to really see what communication has taken place in certain areas and can make decisions on that. Later, if things come up again, he can always go back in OSN and see what was said at that moment in time. Integrating OSN in the APEX applications enhances the user experience, makes the lives of the developers easier and gives a better overview to project managers. Incidentally, you may already know Dimitri and Martin, since both are Oracle Ace Directors. I ran into Martin at the Ace Director briefings Friday before the conference started, and at that point, he wasn’t sure he’d have time to enter the Challenge. After some coaxing, he and Dimitri agreed to give it a go and banged out their entry on Tuesday night, or more accurately, very early Wednesday morning, the day of the Challenge judging. I think they said it took them about four hours of hardcore coding to get it done, very much like a traditional hackathon, which is essentially a code sprint from idea to finished product. Here are some screenshots of the workflow they built. #gallery-1 { margin: auto; } #gallery-1 .gallery-item { float: left; margin-top: 10px; text-align: center; width: 33%; } #gallery-1 img { border: 2px solid #cfcfcf; } #gallery-1 .gallery-caption { margin-left: 0; } I love this idea, i.e. closing the loop between web developers and users, a very common pain point, and so did our judges. Speaking of, special thanks to our panel of three judges: Reggie Bradford (@reggiebradford), serial entrepreneur, founder of Vitrue and SVP of Cloud Product Development at Oracle Robert Hipps (@roberthipps), VP of Development for Oracle Social Network and my former boss Roland Smart (@rsmartx), VP of Social Marketing and the brains behind the Oracle Social Developer Community Finally, thanks to everyone who made this possible, including: The three other teams from HarQen (@harqen), TEAM Informatics (@teaminformatics) and Fishbowl Solutions (@fishbowle20) featuring Friend of the ‘Lab John Sim (@jrsim_uix), who finished and presented entries. I’ll be posting the details of their work this week. The one guy who finished an entry, but couldn’t make the judging, Bex Huff (@bex). Bex rallied from a hospitalization due to an allergic reaction during the show; he’s fine, don’t worry. I’ll post details of his work next week, too. The 40-plus people who registered to compete in the Challenge. Noel for all his hard work, sample code, and flying monkey target, more on that to come. The Oracle Social Network development team for supporting this event. Everyone in legal and the beta program office for their help. And finally, the Oracle Technology Network (@oracletechnet) for hosting the event and providing countless hours of operational and moral support. Sorry if I’ve missed some people, since this was a huge team effort. This event was a big success, and we plan to do similar events in the future. Stay tuned to this channel for more.

• 7 reasons you had to be at JavaOne Latin America 2012

  - by Bruno.Borges

  Yesterday was 12/12/12, and everybody went crazy on Twitter with cool memes like this one. And maybe you are now wondering why I mentioned 7 (seven) on the blog title. Because I want to play numbers? Yes! Today is 7 days after JavaOne Latin America 2012 is over (... and I had to figure out an excuse for taking so long to blog about it...). So unless you were at JavaOne Latin America this year, here are 7 things you missed: OTN Lounge mini-theatreThere was a mini-theatre holding several lightning talks. We had people from SouJava JUG, GoJava JUG, Globalcode, and several other Java gurus and companies running demos, talks, and even more. For example, @drspockbr talked about the ScrumToys project, that demonstrates the power of JSF. Hands On Lab for JAX-RS and WebSocketsOne of the cool things to do during JavaOne is to come to these Hands On labs and really do something using new technologies with the help of experts. This one in particular, was covered by me, Arun Gupta, and Reza Rahman. The HOL had more people than laptops (and we had 48 laptops!) interested on understanding and learning about the new stuff that is coming within Java EE 7. Things like JAX-RS, Server-sent Events and WebSockets. Hey, if you want to try this HOL by yourself, it is available on Github, so go for it! If you have questions, just let me know! Java Community KeynoteThis keynote presented a lot of cool things like startups using Java in their projects, the Duke Awards, SouJava winning the JCP Outstanding Award, the Java Band, and even more! It was really a space where the Java community could present what they are doing and what they want to do. There's a lot of interest on the Adopt-a-JSR program and the Adopt-OpenJDK. There's also an Adopt-a-JavaEE-JSR program! Take a look if you want to participate and Make the Future Java. Java EE (JMS, JAX-RS) sessions from Reza Rahman, the HeavyMetal guyReza is a well know professional and Java EE enthusiast from the communitty who just joined Oracle this year. His sessions were very well attended, perhaps because of a high interest on the new things coming to Java EE 7 like JMS 2.0 and JAX-RS 2.0. If you want to look at what he did at this JavaOne edition, read his blog post. By the way, if you like Java and heavymetal, you should follow him on Twitter as well! :-) Java EE (WebSockets, HTML5) sessions from Arun Gupta, the GlassFish guyIf you don't know Arun Gupta, no worries. You will have time to know about him while you read his Java EE 6 Pocket Guide. Arun has been evangelizing Java EE for a long time, and is now spreading his word about the new upcoming version Java EE 7. He gave one talk about HTML5 Productivity on the Java EE 7 platform, and another one on building web apps with WebSockets. Pretty neat! Arun blogged about JavaOne Latin America as well. Read it here. Java Embedded and JavaFXIf there are two things that are really trending in the Java World right now besides Java EE 7, certainly they are JavaFX and Java Embedded. There were 14 talks covering Java Embedded, from Java Cards to Raspberry.pi, from Java ME to Java on your TV with Ginga-J. The Internet of Things is becoming true, and Java is the only platform today that can connect it all in an standardized and concise way. JavaFX gained a lot of attention too. There were 8 sessions covering what the platform has to offer in terms of Rich User Experience. The JavaFX Scene Builder is an awesome tool to start playing designing an UI, and coding for JavaFX is like coding Swing with 8 hands, one holding your coffee cup. You can achieve a lot, with your two hands (unless, you really have 8 hands, then you can achieve 4 times more :-). If you want to read more about JavaFX, go to Stephen Chin's blog post. GlassFish and Friends Party, 1st edition at JavaOne Lating AmericaThis is probably the thing that I'm most proud. We brought to Brasil the tradition of holding a happy hour for all GlassFish, Java EE friends. This party started almost 7 years ago in San Francisco, and it was about time to bring it to Brazil! The party happened on Tuesday night, right after JavaOne General Keynote, at the Tribeca Pub. We had about 80 attendees and met a lot of Java EE developers there! People from JUGs, Oracle, Locaweb and Red Hat showed up too, including some execs from Oracle that didn't resist and could not miss a party like this one.Lots of caipirinhas, beer and food to everyone, some cool music... even The Fish walking around the party with Juggy!You can see more photos from the party on an album I shared with the recently created GlassFish Brasil community on Google+ here (but you may be more interested in joining the GlassFish english community). There's also more pictures that Arun took and shared on this link. So now you may want to consider coming to Brazil next year! Java EE 7 is on its way, and Brazil is happily and patiently waiting for it, with a lot of enthusiasm. By the way, GlassFish and Java EE 6 just celebrated a Happy Birthday!

• Interview with Ronald Bradford about MySQL Connect

  - by Keith Larson

  Ronald Bradford,  an Oracle ACE Director has been busy working with  database consulting, book writing (EffectiveMySQL) while traveling and speaking around the world in support of MySQL. I was able to take some of his time to get an interview on this thoughts about theMySQL Connect conference. Keith Larson: What where your thoughts when you heard that Oracle was going to provide the community the MySQL Conference ?Ronald Bradford: Oracle has already been providing various different local community events including OTN Tech Days and  MySQL community days. These are great for local regions both in the US and abroad.  In previous years there has been an increase of content at Oracle Open World, however that benefits the Oracle community far more then the MySQL community.  It is good to see that Oracle is realizing the benefit in providing a large scale dedicated event for the MySQL community that includes speakers from the MySQL development teams, invested companies in the ecosystem and other community evangelists.I fully expect a successful event and look forward to hopefully seeing MySQL Connect at the upcoming Brazil and Japan OOW conferences and perhaps an event on the East Coast.Keith Larson: Since you are part of the content committee, what did you think of the submissions that were received during call for papers?Ronald Bradford: There was a large number of quality submissions to the number of available presentation sessions. As with the previous years as a committee member for the annual MySQL conference, there is always a large variety of common cornerstone MySQL features as well as new products and upcoming companies sharing their MySQL experiences. All of the usual major players in the ecosystem will in presenting at MySQL Connect including Facebook, Twitter, Yahoo, Continuent, Percona, Tokutek, Sphinx and Amazon to name a few.  This is ensuring the event will have a large number of quality speakers and a difficult time in choosing what to attend. Keith Larson: What sessions do you look forwarding to attending? Ronald Bradford: As with most quality conferences you can only be in one place at one time, so with multiple tracks per session it is always difficult to decide. The continued work and success with MySQL Cluster, and with a number of sessions I am sure will be popular. The features that interest me the most are around the optimizer, where there are several sessions on new features, and on the importance of backups. There are three presentations in this area to choose from.Keith Larson: Are you going to cover any of the content in your books at your MySQL Connect sessions?Ronald Bradford: I will be giving two presentations at MySQL Connect. The first will include the techniques available for creating better indexes where I will be touching on some aspects of the first Effective MySQL book on Optimizing SQL Statements.  In my second presentation from experiences of managing 500+ AWS MySQL instances, I will be touching on areas including SQL tuning, backup and recovery and scale out with replication.   These are the key topics of the initial books in the Effective MySQL series that focus on performance, scalability and business continuity.  The books however cover a far greater amount of detail then can be presented in a 1 hour session. Keith Larson: What features of MySQL 5.6 do you look forward to the most ?Ronald Bradford: I am very impressed with the optimizer trace feature. The ability to see exposed information is invaluable not just for MySQL 5.6, but to also apply information discerned for optimizing SQL statements in earlier versions of MySQL.  Not everybody understands that it is easy to deploy a MySQL 5.6 slave into an existing topology running an older version if MySQL for evaluation of many new features.  You can use the new mysqlbinlog streaming feature for duplicating master binary logs on an older version with a MySQL 5.6 slave.  The improvements in instrumentation in the Performance Schema are exciting.   However, as with my upcoming Replication Techniques in Depth title, that will be available for sale at MySQL Connect, there are numerous replication features, some long overdue with provide significant management benefits. Crash Save Slaves, Global transaction Identifiers (GTID)  and checksums just to mention a few.Keith Larson: You have been to numerous conferences, what would you recommend for people at the conference? Ronald Bradford: Make the time to meet and introduce yourself to the speakers that cover the topics that most interest you. The MySQL ecosystem has a very strong community.  The relationships you build with presenters, developers and architects in MySQL can be invaluable, however they are created over time. Get to know these people, interact with them over time.  This is the opportunity to learn more then just the content from a 1 hour session. Keith Larson: Any additional tips to handling the long hours ? Ronald Bradford: Conferences can be hard, especially with all the post event drinking.  This is a two day event and I am sure will include additional events on Friday and Saturday night so come well prepared, and leave work behind. Take the time to learn something new.   You can always catchup on sleep later. Keith Larson: Thank you so much for taking some time to do this I look forward to seeing you at the MySQL Connect conference.  Please stay tuned here for more updates on MySQL.

• How to display a dependent list box disabled if no child data exist

  - by frank.nimphius

  A requirement on OTN was to disable the dependent list box of a model driven list of value configuration whenever the list is empty. To disable the dependent list, the af:selectOneChoice component needs to be refreshed with every value change of the parent list, which however already is the case as the list boxes are already dependent. When you create model driven list of values as choice lists in an ADF Faces page, two ADF list bindings are implicitly created in the PageDef file of the page that hosts the input form. At runtime, a list binding is an instance of FacesCtrlListBinding, which exposes getItems() as a method to access a list of available child data (java.util.List). Using Expression Language, the list is accessible with #{bindings.list_attribute_name.items} To dynamically set the disabled property on the dependent af:selectOneChoice component, however, you need a managed bean that exposes the following two methods //empty – but required – setter method public void setIsEmpty(boolean isEmpty) {} //the method that returns true/false when the list is empty or //has values public boolean isIsEmpty() {   FacesContext fctx = FacesContext.getCurrentInstance();   ELContext elctx = fctx.getELContext();   ExpressionFactory exprFactory =                          fctx.getApplication().getExpressionFactory();   ValueExpression vexpr =                       exprFactory.createValueExpression(elctx,                         "#{bindings.EmployeeId.items}",                       Object.class);   List employeesList = (List) vexpr.getValue(elctx);                        return employeesList.isEmpty()? true : false;      } If referenced from the dependent choice list, as shown below, the list is disabled whenever it contains no list data <! --  master list --> <af:selectOneChoice value="#{bindings.DepartmentId.inputValue}"                                  label="#{bindings.DepartmentId.label}"                                  required="#{bindings.DepartmentId.hints.mandatory}"                                   shortDesc="#{bindings.DepartmentId.hints.tooltip}"                                   id="soc1" autoSubmit="true">      <f:selectItems value="#{bindings.DepartmentId.items}" id="si1"/> </af:selectOneChoice> <! --  dependent  list --> <af:selectOneChoice value="#{bindings.EmployeeId.inputValue}"                                   label="#{bindings.EmployeeId.label}"                                      required="#{bindings.EmployeeId.hints.mandatory}"                                   shortDesc="#{bindings.EmployeeId.hints.tooltip}"                                   id="soc2" disabled="#{lovTestbean.isEmpty}"                                   partialTriggers="soc1">     <f:selectItems value="#{bindings.EmployeeId.items}" id="si2"/> </af:selectOneChoice>

• Thought Oracle Usability Advisory Board Was Stuffy? Wrong. Justification for Attending OUAB: ROI

  - by ultan o'broin

  Looking for reasons tell your boss why your organization needs to join the Oracle Usability Advisory Board or why you need approval to attend one of its meetings (see the requirements)? Try phrases such as "Continued Return on Investment (ROI)", "Increased Productivity" or "Happy Workers". With OUAB your participation is about realizing and sustaining ROI across the entire applications life-cycle from input to designs to implementation choices and integration, usage and performance and on measuring and improving the onboarding and support experience. If you think this is a boring meeting of middle-aged people sitting around moaning about customizing desktop forms and why the BlackBerry is here to stay, think again! How about this for a rich agenda, all designed to engage the audience in a thought-provoking and feedback-illiciting day of swirling interactions, contextual usage, global delivery, mobility, consumerizationm, gamification and tailoring your implementation to reflect real users doing real work in real environments.  Foldable, rollable ereader devices provide a newspaper-like UK for electronic news. Or a way to wrap silicon chips, perhaps. Explored at the OUAB Europe Meeting (photograph from Terrace Restaurant in TVP. Nom.) At the 7 December 2012 OUAB Europe meeting in Oracle Thames Valley Park, UK, Oracle partners and customers stepped up to the mic and PPT decks with a range of facts and examples to astound any UX conference C-level sceptic. Over the course of the day we covered much ground, but it was all related in a contextual, flexibile, simplication, engagement way aout delivering results for business: that means solving problems. This means being about the user and their tasks and how to make design and technology transforms work into a productive activity that users and bean counters will be excited by. The sessions really gelled for me: 1. Mobile design patterns and the powerful propositions for customers and partners offered by using the design guidance with Oracle ADF Mobile. Customers' and partners' developers existing ADF developers are now productive, efficient ADF Mobile developers applying proven UX guidance using ADF Mobile components and other Oracle Fusion Middleware in the development toolkit. You can find the Mobile UX Design Patterns and Guidance on Building Mobile Apps on OTN. 2. Oracle Voice and Apps. How this medium offers so much potentual in the enterprise and offers a window in Fusion Apps cloud webservices, Oracle RightNow NLP and Nuance technology. Exciting stuff, demoed live on a mobile phone. Stay tuned for more features and modalities and how you can tailor your own apps experience.  3. Oracle RightNow Natural Language Processing (NLP) Virtual Assistant technology (Ella): how contextual intervention and learning from users sessions delivers a great personalized UX for users interacting with Ella, a fifth generation VA to solve problems and seek knowledge. 4. BYOD Keynote: A balanced keynote address contrasting Fujitsu's explaining of the conceprt, challenges, and trends and setting the expectation that BYOD must be embraced in a flexible way,  with the resolute, crafted high security enterprise requirements that nuancing the BYOD concept and proposals with the realities of their world of water tight information and device sharing policies. Fascinating stuff, as well providing anecdotes to make us thing about out own DYOD Deployments. One size does not fit all. 5. Icon Cultural Surveys Results and Insights Arising: Ever wondered about the cultural appropriateness of icons used in software UIs and how these icons assessed for global use? Or considered that social media "Like" icons might be  unacceptable hand gestures in culture or enterprise? Or do the old world icons like Save floppy disk icons still find acceptable? Well the survey results told you. Challenges must be tested, over time, and context of use is critical now, including external factors such as the internet and social media adoption. Indeed the fears about global rejection of the face and hand icons was not borne out, and some of the more anachronistic icons (checkbooks, microphones, real-to-real tape decks, 3.5" floppies for "save") have become accepted metaphors for current actions. More importantly the findings brought into focus the reason for OUAB - engage with and illicit feedback though working groups before we build anything. 6. EReaders and Oracle iBook: What is the uptake and trends of ereaders? And how about a demo of an iBook with enterprise apps content?  Well received by the audience, the session included a live running poll of ereader usage. 7. Gamification Design Jam: Fun, hands on event for teams of Oracle staff, partners and customers, actually building gamified flows, a practice that can be applied right away by customers and partners.  8. UX Direct: A new offering of usability best practices, coming to an external website for you in 2013. FInd a real user, observe their tasks, design and approve, build and measure. Simple stuff to improve apps implications no end. 9. FUSE (an internal term only, basically Fusion Simplified Experience): demo of the new Face of Fusion Applications: inherently mobile, simple to use, social, personalizable and FAST, three great demos from the HCM, CRM and ICT world on how these UX designs can be used in different ways. So, a powerful breadth and depth of UX solutions and opporunities for customers and partners to engage with and explore how they can make their users happy and benefit their business reaping continued ROI from those apps investments.

• How-to populate different select list content per table row

  - by frank.nimphius

  Normal 0 false false false EN-US X-NONE X-NONE /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;} A frequent requirement posted on the OTN forum is to render cells of a table column using instances of af:selectOneChoices with each af:selectOneChoice instance showing different list values. To implement this use case, the select list of the table column is populated dynamically from a managed bean for each row. The table's current rendered row object is accessible in the managed bean using the #{row} expression, where "row" is the value added to the table's var property. <af:table var="row">   ...   <af:column ...>     <af:selectOneChoice ...>         <f:selectItems value="#{browseBean.items}"/>     </af:selectOneChoice>   </af:column </af:table> The browseBean managed bean referenced in the code snippet above has a setItems and getItems method defined that is accessible from EL using the #{browseBean.items} expression. When the table renders, then the var property variable - the #{row} reference - is filled with the data object displayed in the current rendered table row. The managed bean getItems method returns a List<SelectItem>, which is the model format expected by the f:selectItems tag to populate the af:selectOneChoice list. public void setItems(ArrayList<SelectItem> items) {} //this method is executed for each table row public ArrayList<SelectItem> getItems() {   FacesContext fctx = FacesContext.getCurrentInstance();   ELContext elctx = fctx.getELContext();   ExpressionFactory efactory =          fctx.getApplication().getExpressionFactory();          ValueExpression ve =          efactory.createValueExpression(elctx, "#{row}", Object.class);      Row rw = (Row) ve.getValue(elctx);         //use one of the row attributes to determine which list to query and   //show in the current af:selectOneChoice list  // ...  ArrayList<SelectItem> alsi = new ArrayList<SelectItem>();  for( ... ){      SelectItem item = new SelectItem();        item.setLabel(...);        item.setValue(...);        alsi.add(item);   }   return alsi;} For better performance, the ADF Faces table stamps it data rows. Stamping means that the cell renderer component - af:selectOneChoice in this example - is instantiated once for the column and then repeatedly used to display the cell data for individual table rows. This however means that you cannot refresh a single select one choice component in a table to change its list values. Instead the whole table needs to be refreshed, rerunning the managed bean list query. Be aware that having individual list values per table row is an expensive operation that should be used only on small tables for Business Services with low latency data fetching (e.g. ADF Business Components and EJB) and with server side caching strategies for the queried data (e.g. storing queried list data in a managed bean in session scope).
