• Meet Thomas, the Most Innovational person in Oracle Direct EMEA of Q1

  - by Maria Sandu

  Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 Thomas was voted, by his peers,  the most Innovational person in Oracle Direct EMEA of Q1, the first quarter of this fiscal! Thomas, a Business Development Consultant at Oracle Direct’s Applications Team, taught himself how to use and leverage the power of social engagement consistent with Oracle’s Social Media Policy.  From these learning's he provided both his and other applications teams in Dublin with huge amounts of training and has presented his findings to the teams on more than one occasion. It is important to recognise that this isn't just a great idea....it actually works! The results speak for themselves. Thomas is engaging with customers and prospects via their preferred channel of communication and creating a strong personal social brand. We congratulate Thomas for his efforts of raising Social Media to the next level within Business Development Group. He put a lot of work into Social Selling, as one of the first within the BDG and set the example for a new innovative approach on how to sell anno 2013. He deserves to be recognized for this. His contribution to social media has been a great inspiration for all Business Development Consultants or Business Relationship Consultants. He knows what he talks about and has great conversion rates out of his social media campaigns. And he doesn't mind sharing his knowledge with everybody. Great effort in searching for new ways of communication and social selling. Thomas has shown great initiative towards leveraging the social media and networks (twitter, linkedin) to find new business opportunities in a previously way. He has shown great out-of-the-box thinking while addressing new companies and prospects and has shared those experiences and ideas to help his colleagues use the same approach. This included a presentation, informational emails and a general helpful attitude from him. He also shared his success stories from his innovational approach.  Thomas is showing initiative with an innovative and fresh character, truly helping people to try something new  with a focus on selling across channels and working for the CRM team which is focused on selling social. We think the way Thomas positions social, by using social is innovative and inspirational. What better way to tell your clients do social, by engaging with them on a social platform? Going always the extra mile, we believe, that Thomas Brits, is an innovator from the day he walked into Oracle Direct. The way Thomas operates on the work floor by introducing new ideas to find the best opportunities as possible shows he runs the extra mile for coming up with new ideas around how to engage with customers more efficiently for instance via Social Media. Thomas also organises power hours/days for the team.

• MEB Support to NetBackup MMS

  - by Hema Sridharan

  In MySQL Enterprise Backup 3.6, new option was introduced to support backup to tapes via SBT interface. SBT stands for System Backup to Tape, an Oracle API that helps to perform backup and restore jobs via media management software such as Oracle's Secure Backup (OSB). There are other storage managers like IBM's Tivoli Storage Manager (TSM) and Symantec's Netbackup (NB) which are also supported by MEB but we don't guarantee that it will function as expected for every release. MEB supports SBT API version 2.0 In this blog, I am primarily going to focus the interface of MEB and Symantec's NB. If we are using tapes for backup, ensure that tape library and tape drives are compatible. Test Setup 1. Install NB 7.5 master and media servers in Linux OS. ( NB 7.1 can also be used but for testing purpose I used NB 7.5)2. Install MEB 3.8 also in Linux OS.3. Install NB admin console in your windows desktop and configure the NB master server from there. Note: Ensure that you have root user permission to install NetBackup. Configuration Steps for MEB and NB Once MEB and NB are installed, Ensure that NB is linked to MEB by specifying the library /usr/openv/netbackup/bin/libobk.so64 in the mysqlbackup command line using --sbt-lib-path. Configure the NB master server from windows console. That is configure the storage units by specifying the Storage unit name, Disk type, Media Server name etc.  Create NetBackup policies that are user selectable. But please make sure that policy type is "Oracle".  Define the clients where MEB will be executed. Some times this will be different host where MEB is run or some times in same Media server where NB and tapes are attached. Now once the installation and configuration steps are performed for MEB and NB, the next part is the actual execution.MEB should be run as single file backup using --backup-image option with prefix sbt:(it is a tag which tells MEB that it should stream the backup image through the SBT interface) which is sent to NB client via SBT interface . The resulting backup image is stored where NB stores the images that it backs up. The following diagram shows how MEB interacts with MMS through SBT interface. Backup The following parameters should also be ready for the execution,    --sbt-lib-path : Path to SBT library specific to NetBackup MMS. SBT lib for NetBackup  is in /usr/openv/netbackup/bin/libobk.so64    --sbt-environment: Environment variables must be defined specific to NetBackup. In our example below, we use     NB_ORA_SERV=myserver.com,    NB_ORA_CLIENT=myserver.com,    NB_ORA_POLICY=NBU-MEB    ORACLE_HOME = /export/home2/tmp/hema/mysql-server/ ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- ./mysqlbackup --port=13000 --protocol=tcp --user=root --backup-image=sbt:bkpsbtNB --sbt-lib-path=/usr/openv/netbackup/bin/libobk.so64 --sbt-environment="NB_ORA_SERV=myserver.com, NB_ORA_CLIENT=myserver.com, NB_ORA_POLICY=NBU-MEB, ORACLE_HOME=/export/home2/tmp/hema/mysql-server/” --backup-dir=/export/home2/tmp/hema/MEB_bkdir/ backup-to-image ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Once backup is completed successfully, this should appear in Activity Monitor in NetBackup Console.For restore,  image contents has to be extracted using image-to-backup-dir command and then apply-log and copy-back steps are applied. ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- ./mysqlbackup --sbt-lib-path=/usr/openv/netbackup/bin/libobk.so64  --backup-dir=/export/home2/tmp/hema/NBMEB/ --backup-image=sbt:bkpsbtNB image-to-backup-dir-----------------------------------------------------------------------------------------------------------------------------------Now apply logs as usual, shutdown the server and perform restore, restart the server and check the data contents. ./mysqlbackup   ---backup-dir=/export/home2/tmp/hema/NBMEB/  apply-log ./mysqlbackup --datadir=/export/home2/tmp/hema/mysql-server/mysql-5.5-meb-repo/mysql-test/var/mysqld.1/data/  --backup-dir=/export/home2/tmp/hema/MEB_bkpdir/ innodb_log_files_in_group=2 --innodb_log_file_size=5M --user=root --port=13000 --protocol=tcp copy-back The NB console should show 'Restore" job as done. If you don't see that there is something wrong with MEB or NetBackup.You can also refer to more detailed steps of MEB and NB integration in whitepaper here

  WEBCAST THURSDAY!! 03/22/12 Do you need to lower costs? Raise Productivity? Foster Innovation? Improve Online Engagement? But you’re still stuck with Documentum? Step away from the ledge – there is hope – let us help you. Top 4 Content Imperatives · Lower Costs - Reduce labor, maintenance fees, storage and electrical consumption · Raise Productivity - Automation and integration, communication, findability · Foster Innovation - Enable collaboration, expertise location · Improve Online Engagement – enable user-driven, dynamic marketing initiatives With the coming technology wave we see four content imperatives. Every organization has had to reduce costs, cost cutting has become a way of life. Everyone is working three jobs as positions are eliminated. And so we have to reduce labor, reduce maintenance, and reduce money we are wasting on things like storing content that is redundant or no longer useful. We also, to fill that gap, need to raise productivity. Knowledge workers represent the fastest growing segment of the workforce, accounting for 40%-75% of the employees at organizations in sectors like financial services, life sciences, healthcare and retail.  What’s more, their wages total 18 percent of the United States GDP. And so we can’t afford information systems that don’t let our top performers be the best they can be. We look to automate the content processes, provide ways to integrate that content into our processes, provide communication to make decisions, and to make content more findable so people can make the right decision and move the process forward. And really to get ourselves out of the current financial status, we can only cut costs so far. We have to innovate out of economic tough times – to find new products and new markets. And to enable the innovation process, we have to enable collaboration and expertise location. So much of innovation is about building on innovations that have come before. To solve problems, we have to be able to find what our organization has already created. We find that problems we need to solve have already been solved if we can find the right document, the right person. So we have to provide systems that enable us to stand on the shoulders of our organization’s accomplishments. Good content drives great marketing. Online engagement is growing as an absolute necessity for modern growing marketing organizations that require the business users be enabled for dynamic marketing content creation, updates and targeted content creation and management. Unfortunately – if you are currently stuck with Documentum, you are really lacking in your Web Experience Management capabilities. Documentum previously used FatWire for web publishing. Now FatWire is part of Oracle. Oracle provides powerful web engagement capabilities: Increase sales and loyalty by optimizing online engagement Create, manage and moderate contextually relevant, targeted and interactive online experiences Optimize customer engagement across, web, mobile and social channels Manage large scale multichannel global online presence with integration to enterprise applications Enable business users to control their content and make their own updates Publish content from native files – enable navigation of project documents, procedures, policy information Enable content display and updates from existing web applications – one click to drag and drop content management functionality So you get the ability to self-publish information and make it navigable, to move the process of publishing from IT to business users, and the ability to address a whole new area of user engagement with web experience management. So… if you are still stuck with Documentum and don’t know what to do – contact us – not only will Oracle help you step away from the ledge, but also with the MoveOff Documentum program, we are offering you a way – trade-in your Documentum licenses for a 100% credit on Oracle WebCenter.

• Recent improvements in Console Performance

  - by loren.konkus

  Recently, the WebLogic Server development and support organizations have worked with a number of customers to quantify and improve the performance of the Administration Console in large, distributed configurations where there is significant latency in the communications between the administration server and managed servers. These improvements fall into two categories: Constraining the amount of time that the Console stalls waiting for communication Reducing and streamlining the amount of data required for an update A few releases ago, we added support for a configurable domain-wide mbean "Invocation Timeout" value on the Console's configuration: general, advanced section for a domain. The default value for this setting is 0, which means wait indefinitely and was chosen for compatibility with the behavior of previous releases. This configuration setting applies to all mbean communications between the admin server and managed servers, and is the first line of defense against being blocked by a stalled or completely overloaded managed server. Each site should choose an appropriate timeout value for their environment and network latency. In the next release of WebLogic Server, we've added an additional console preference, "Management Operation Timeout", to the Console's shared preference page. This setting further constrains how long certain console pages will wait for slowly responding servers before returning partial results. While not all Console pages support this yet, key pages such as the Servers Configuration and Control table pages and the Deployments Control pages have been updated to support this. For example, if a user requests a Servers Table page and a Management Operation Timeout occurs, the table is displayed with both local configuration and remote runtime information from the responding managed servers and only local configuration information for servers that did not yet respond. This means that a troublesome managed server does not impede your ability to manage your domain using the Console. To support these changes, these Console pages have been re-written to use the Work Management feature of WebLogic Server to interact with each server or deployment concurrently, which further improves the responsiveness of these pages. The basic algorithm for these pages is: For each configuration mbean (ie, Servers) populate rows with configuration attributes from the fast, local mbean server Find a WorkManager For each server, Create a Work instance to obtain runtime mbean attributes for the server Schedule Work instance in the WorkManager Call WorkManager.waitForAll to wait WorkItems to finish, constrained by Management Operation Timeout For each WorkItem, if the runtime information obtained was not complete, add a message indicating which server has incomplete data Display collected data in table In addition to these changes to constrain how long the console waits for communication, a number of other changes have been made to reduce the amount and scope of managed server interactions for key pages. For example, in previous releases the Deployments Control table looked at the status of a deployment on every managed server, even those servers that the deployment was not currently targeted on. (This was done to handle an edge case where a deployment's target configuration was changed while it remained running on previously targeted servers.) We decided supporting that edge case did not warrant the performance impact for all, and instead only look at the status of a deployment on the servers it is targeted to. Comprehensive status continues to be available if a user clicks on the 'status' field for a deployment. Finally, changes have been made to the System Status portlet to reduce its impact on Console page display times. Obtaining health information for this display requires several mbean interactions with managed servers. In previous releases, this mbean interaction occurred with every display, and any delay or impediment in these interactions was reflected in the display time for every page. To reduce this impact, we've made several changes in this portlet: Using Work Management to obtain health concurrently Applying the operation timeout configuration to constrain how long we will wait Caching health information to reduce the cost during rapid navigation from page to page and only obtaining new health information if the previous information is over 30 seconds old. Eliminating heath collection if this portlet is minimized. Together, these Console changes have resulted in significant performance improvements for the customers with large configurations and high latency that we have worked with during their development, and some lesser performance improvements for those with small configurations and very fast networks. These changes will be included in the 11g Rel 1 patch set 2 (10.3.3.0) release of WebLogic Server.

• Spotlight on an office - Denmark

  - by jessica.ebbelaar(at)oracle.com

  Hi, my name is Michael. I work as an Intern at the Danish office in Ballerup. My job is a part-time position beside my bachelor study in International Business at Copenhagen Business School. I joined Oracle end of February last year, and what a thrilling ride it has been! Last year, when I was offered the position, there was no doubt that I wanted to go for it. Back then, I only had little idea about Oracle as a company and what kind of exciting assignments lay ahead of me. My main role is internal communications, i.e. editor of a monthly employee’s news letter; Newszone. It is an interesting task, since it requires that I am updated on the different activities that take place within the Oracle Denmark office. I try to bring interesting articles, which are relevant and interesting news to my colleagues and it allows me to interact with many different persons at the office and to learn from their experience, which give me great inspiration and ideas for the magazine. Besides being the editor of Newszone, I also make sure that other communication flow freely at the Oracle Denmark office. I do this through our LCD screen channels. I update the internal channel with the latest information and important messages for employees, and on the external channel I circulate marketing videos featuring Oracle products and customer reference stories. In addition to this, I have the responsibility acting as a content manager of the Local Communication Denmark site on MyOracle (UCM). These are more or less my usual work assignments. On top of these I take care of various ad hoc assignments such as updating the GCM database, renew newspaper subscriptions etc. The Oracle Denmark office Being part of the local employees club I also assist with arranging social events outside working hours – e.g. evenings at the theater or cinema or by attending many of the sportsactivities;such as our running club, cycling club, food club and book club. These activities have indeed helped me grow my personal network within Oracle.  The office is packed with engaging, high-paced and motivated people who manage to take time off to spend a day attending Corporate Social Responsibility initiatives, one of them being GVD (Global Volunteer Day) with approximately 40 employees attending. This proofs some of the social responsible aspects of Oracle. I was positively surprised on how the office (named O-Zone) is designed. The office is designed into three distinct zones, namely Call zone, Project and Dialogue zone and Quiet zone, having different working environments for different job roles. The other thing which I like is that you do not have your own desk, which means you get to sit next to different people every day, getting new ideas and inspiration as well as getting to know more people in the organization you work in. To sum up: If you are considering pursuing an intern or a career after graduation in Oracle, do it! You will not regret it. It has given me many relevant practical experiences beside my study, and I am sure many great experiences will await you too.   Want to know more about the current vacancies in Denmark?

  Mind Reading With The Raspberry Pi At JavaOne in San Francisco I did a session entitled "Do You Like Coffee with Your Dessert? Java and the Raspberry Pi".  As part of this I showed some demonstrations of things I'd done using Java on the Raspberry Pi.  This is the first part of a series of blog entries that will cover all the different aspects of these demonstrations. A while ago I had bought a MindWave headset from Neurosky.  I was particularly interested to see how this worked as I had had the opportunity to visit Neurosky several years ago when they were still developing this technology.  At that time the 'headset' consisted of a headband (very much in the Bjorn Borg style) with a sensor attached and some wiring that clearly wasn't quite production ready.  The commercial version is very simple and easy to use: there are two sensors, one which rests on the skin of your forehead, the other is a small clip that attaches to your earlobe. Typical EEG sensors used in hospitals require lots of sensors and they all need copious amounts of conductive gel to ensure the electrical signals are picked up.  Part of Neurosky's innovation is the development of this simple dry-sensor technology.  Having put on the sensor and turned it on (it powers off a single AAA size battery) it collects data and transmits it to a USB dongle plugged into a PC, or in my case a Raspberry Pi. From a hacking perspective the USB dongle is ideal because it does not require any special drivers for any complex, low level USB communication.  Instead it appears as a simple serial device, which on the Raspberry Pi is accessed as /dev/ttyUSB0.  Neurosky have published details of the command protocol.  In addition, the MindSet protocol document, including sample code for parsing the data from the headset, can be found here. To get everything working on the Raspberry Pi using Java the first thing was to get serial communications going.  Back in the dim distant past there was the Java Comm API.  Sadly this has grown a bit dusty over the years, but there is a more modern open source project that provides compatible and enhanced functionality, RXTXComm.  This can be installed easily on the Pi using sudo apt-get install librxtx-java.  Next I wrote a library that would send commands to the MindWave headset via the serial port dongle and read back data being sent from the headset.  The design is pretty simple, I used an event based system so that code using the library could register listeners for different types of events from the headset.  You can download a complete NetBeans project for this here.  This includes javadoc API documentation that should make it obvious how to use it (incidentally, this will work on platforms other than Linux.  I've tested it on Windows without any issues, just by changing the device name to something like COM4). To test this I wrote a simple application that would connect to the headset and then print the attention and meditation values as they were received from the headset.  Again, you can download the NetBeans project for that here. Oracle recently released a developer preview of JavaFX on ARM which will run on the Raspberry Pi.  I thought it would be cool to write a graphical front end for the MindWave data that could take advantage of the built in charts of JavaFX.  Yet another NetBeans project is available here.  Screen shots of the app, which uses a very nice dial from the JFxtras project, are shown below. I probably should add labels for the EEG data so the user knows which is the low alpha, mid gamma waves and so on.  Given that I'm not a neurologist I suspect that it won't increase my understanding of what the (rather random looking) traces mean. In the next blog I'll explain how I connected a LEGO motor to the GPIO pins on the Raspberry Pi and then used my mind to control the motor!

• Removing Barriers to Create Effective Data Models

  After years of creating and maintaining data models, I have started to notice common barriers that decrease the accuracy and usefulness of models. In my opinion, the main causes of these barriers are the lack of knowledge and communication from within a company. The lack of knowledge in regards to data models or data modeling can take many forms. Company Culture Knowledge Whether documented or undocumented, existing business rules of a company can affect how data is modeled. For example, if a company only allows 1 assigned person per customer to be able to manipulate a customer’s record then then a data model that includes an associated table that joins customers and employee’s would be unneeded because that would allow for the possibility of multiple employees to handle a customer because of the potential for a many to many relationship between Customers and Employees. Technical Knowledge Depending on the data modeler’s proficiency in modeling data they can inadvertently cause issues and/or complications with a design without even noticing. It is important that companies share data modeling responsibilities so that the models are developed from multiple perspectives of a system, company and the original problem.  In addition, the tools that a company selects to create data models can also affect the accuracy of the model if designer are not familiar with the tools or the tools are too complex to use for the designer. Existing System Knowledge In order for a data modeler to model data for an existing system so that new changes can be applied to a system then they need to at least know the basic concepts of a system so that they can work within it. This will promote reusability of data and prevent the chance of duplicating data. Project Knowledge This should be pretty obvious, but it is very hard to create an accurate data model without knowing what data needs to be modeled. I have always found it strange that I have been asked to start modeling data prior to a client formalizing any requirements. Usually when this happens I have to make several iterations to a model, and the client still does not know exactly what they want.  In addition additional issues can arise when certain stakeholders of a project are not consulted prior to the design or after the project is over because it can cause miss understandings and confusion by the end user as well as possibly not solving the original problem for which a project is intended to solve. One common thread between each type of knowledge is that they can all be avoided through the use of good communication. For example, if a modeler is new to a company then they should ask older employees about any business specific rules that may be documented or undocumented that must be applied to projects in general. Furthermore, if a modeler is not really familiar with a specific data modeling software then they need to speak up and ask for help form other employees or their manager. This will not only help the modeler in the project, but also help them in future projects that they do for the company. Additionally, if a project is not clearly defined prior to a data modeler being assigned the modeling project then it is their responsibility to communicate with the other stakeholders to clarify any part of a project that is unclear so that the data model that is created is accurately aligned with a project.

• The Raspberry Pi JavaFX In-Car System (Part 3)

  - by speakjava

  Ras Pi car pt3 Having established communication between a laptop and the ELM327 it's now time to bring in the Raspberry Pi. One of the nice things about the Raspberry Pi is the simplicity of it's power supply.  All we need is 5V at about 700mA, which in a car is as simple as using a USB cigarette lighter adapter (which is handily rated at 1A).  My car has two cigarette lighter sockets (despite being specified with the non-smoking package and therefore no actual cigarette lighter): one in the centre console and one in the rear load area.  This was convenient as my idea is to mount the Raspberry Pi in the back to minimise the disruption to the very clean design of the Audi interior. The first task was to get the Raspberry Pi to communicate using Wi-Fi with the ELM 327.  Initially I tried a cheap Wi-Fi dongle from Amazon, but I could not get this working with my home Wi-Fi network since it just would not handle the WPA security no matter what I did.  I upgraded to a Wi Pi from Farnell and this works very well. The ELM327 uses Ad-Hoc networking, which is point to point communication.  Rather than using a wireless router each connecting device has its own assigned IP address (which needs to be on the same subnet) and uses the same ESSID.  The settings of the ELM327 are fixed to an IP address of 192.168.0.10 and useing the ESSID, "Wifi327".  To configure Raspbian Linux to use these settings we need to modify the /etc/network/interfaces file.  After some searching of the web and a few false starts here's the settings I came up with: auto lo eth0 wlan0 iface lo inet loopback iface eth0 inet static     address 10.0.0.13     gateway 10.0.0.254     netmask 255.255.255.0 iface wlan0 inet static     address 192.168.0.1     netmask 255.255.255.0     wireless-essid Wifi327     wireless-mode ad-ho0 After rebooting, iwconfig wlan0 reported that the Wi-Fi settings were correct.  However, ifconfig showed no assigned IP address.  If I configured the IP address manually using ifconfig wlan0 192.168.0.1 netmask 255.255.255.0 then everything was fine and I was able to happily ping the IP address of the ELM327.  I tried numerous variations on the interfaces file, but nothing I did would get me an IP address on wlan0 when the machine booted.  Eventually I decided that this was a pointless thing to spend more time on and so I put a script in /etc/init.d and registered it with update-rc.d.  All the script does (currently) is execute the ifconfig line and now, having installed the telnet package I am able to telnet to the ELM327 via the Raspberry Pi.  Not nice, but it works. Here's a picture of the Raspberry Pi in the car for testing In the next part we'll look at running the Java code on the Raspberry Pi to collect data from the car systems.

That definition of DevOps is the – what. The “why” is even easier. Standardized development methodology, clear communication and documented processes supported by a standards-based, proven middleware platform improves application development and management cycles, brings agility and provides greater availability and security to your IT infrastructure.

• JavaOne 2012: Nashorn Edition

  - by $utils.escapeXML($entry.author)

  As with my JavaOne 2012: OpenJDK Edition post a while back (now updated to reflect the schedule of the talks), I find it convenient to have my JavaOne schedule ordered by subjects of interest. Beside OpenJDK in all its flavors, another subject I find very exciting is Nashorn. I blogged about the various material on Nashorn in the past, and we interviewed Jim Laskey, the Project Lead on Project Nashorn in the Java Spotlight podcast. So without further ado, here are the JavaOne 2012 talks and BOFs with Nashorn in their title, or abstract:CON5390 - Nashorn: Optimizing JavaScript and Dynamic Language Execution on the JVM - Monday, Oct 1, 8:30 AM - 9:30 AMThere are many implementations of JavaScript, meant to run either on the JVM or standalone as native code. Both approaches have their respective pros and cons. The Oracle Nashorn JavaScript project is based on the former approach. This presentation goes through the performance work that has gone on in Oracle’s Nashorn JavaScript project to date in order to make JavaScript-to-bytecode generation for execution on the JVM feasible. It shows that the new invoke dynamic bytecode gets us part of the way there but may not quite be enough. What other tricks did the Nashorn project use? The presentation also discusses future directions for increased performance for dynamic languages on the JVM, covering proposed enhancements to both the JVM itself and to the bytecode compiler.CON4082 - Nashorn: JavaScript on the JVM - Monday, Oct 1, 3:00 PM - 4:00 PMThe JavaScript programming language has been experiencing a renaissance of late, driven by the interest in HTML5. Nashorn is a JavaScript engine implemented fully in Java on the JVM. It is based on the Da Vinci Machine (JSR 292) and will be available with JDK 8. This session describes the goals of Project Nashorn, gives a top-level view of how it all works, provides the current status, and demonstrates examples of JavaScript and Java working together.BOF4763 - Meet the Nashorn JavaScript Team - Tuesday, Oct 2, 4:30 PM - 5:15 PMCome to this session to meet the Oracle JavaScript (Project Nashorn) language teamBOF6661 - Nashorn, Node, and Java Persistence - Tuesday, Oct 2, 5:30 PM - 6:15 PMWith Project Nashorn, developers will have a full and modern JavaScript engine available on the JVM. In addition, they will have support for running Node applications with Node.jar. This unique combination of capabilities opens the door for best-of-breed applications combining Node with Java SE and Java EE. In this session, you’ll learn about Node.jar and how it can be combined with Java EE components such as EclipseLink JPA for rich Java persistence. You’ll also hear about all of Node.jar’s mapping, caching, querying, performance, and scaling features.CON10657 - The Polyglot Java VM and Java Middleware - Thursday, Oct 4, 12:30 PM - 1:30 PMIn this session, Red Hat and Oracle discuss the impact of polyglot programming from their own unique perspectives, examining non-Java languages that utilize Oracle’s Java HotSpot VM. You’ll hear a discussion of topics relating to Ruby, Lisp, and Clojure and the intersection of other languages where they may touch upon individual frameworks and projects, and you’ll get perspectives on JavaScript via the Nashorn Project, an upcoming JavaScript engine, developed fully in Java.CON5251 - Putting the Metaobject Protocol to Work: Nashorn’s Java Bindings - Thursday, Oct 4, 2:00 PM - 3:00 PMProject Nashorn is Oracle’s new JavaScript runtime in Java 8. Being a JavaScript runtime running on the JVM, it provides integration with the underlying runtime by enabling JavaScript objects to manipulate Java objects, implement Java interfaces, and extend Java classes. Nashorn is invokedynamic-based, and for its Java integration, it does away with the concept of wrapper objects in favor of direct virtual machine linking to Java objects’ methods provided by a metaobject protocol, providing much higher performance than what could be expected from a scripting runtime. This session looks at the details of the integration, a topic of interest to other language implementers on the JVM and a wider audience of developers who want to understand how Nashorn works.That's 6 sessions tooting the Nashorn this year at JavaOne, up from 2 last year.

• 4 Key Ingredients for the Cloud

  - by Kellsey Ruppel

  It's a short week here with the US Thanksgiving Holiday. So, before we put on our stretch pants and get ready to belly up to the dinner table for turkey, stuffing and mashed potatoes, let's spend a little time this week talking about the Cloud (kind of like the feathery whipped goodness that tops the infamous Thanksgiving pumpkin pie!) But before we dive into the Cloud, let's do a side by side comparison of the key ingredients for each. Cloud Whipped Cream  Application Integration  1 cup heavy cream  Security  1/4 cup sugar  Virtual I/O  1 teaspoon vanilla  Storage  Chilled Bowl It’s no secret that millions of people are connected to the Internet. And it also probably doesn’t come as a surprise that a lot of those people are connected on social networking sites.  Social networks have become an excellent platform for sharing and communication that reflects real world relationships and they play a major part in the everyday lives of many people. Facebook, Twitter, Pinterest, LinkedIn, Google+ and hundreds of others have transformed the way we interact and communicate with one another.Social networks are becoming more than just an online gathering of friends. They are becoming a destination for ideation, e-commerce, and marketing. But it doesn’t just stop there. Some organizations are utilizing social networks internally, integrated with their business applications and processes and the possibility of social media and cloud integration is compelling. Forrester alone estimates enterprise cloud computing to grow to over $240 billion by 2020. It’s hard to find any current IT project today that is NOT considering cloud-based deployments. Security and quality of service concerns are no longer at the forefront; rather, it’s about focusing on the right mix of capabilities for the business. Cloud vs. On-Premise? Policies & governance models? Social in the cloud? Cloud’s increasing sophistication, security in applications, mobility, transaction processing and social capabilities make it an attractive way to manage information. And Oracle offers all of this through the Oracle Cloud and Oracle Social Network. Oracle Social Network is a secure private network that provides a broad range of social tools designed to capture and preserve information flowing between people, enterprise applications, and business processes. By connecting you with your most critical applications, Oracle Social Network provides contextual, real-time communication within and across enterprises. With Oracle Social Network, you and your teams have the tools you need to collaborate quickly and efficiently, while leveraging the organization’s collective expertise to make informed decisions and drive business forward. Oracle Social Network is available as part of a portfolio of application and platform services within the Oracle Cloud. Oracle Cloud offers self-service business applications delivered on an integrated development and deployment platform with tools to rapidly extend and create new services. Oracle Social Network is pre-integrated with the Fusion CRM Cloud Service and the Fusion HCM Cloud Service within the Oracle Cloud. If you are looking for something to watch as you veg on the couch in a post-turkey dinner hangover, you might consider watching these how-to videos! And yes, it is perfectly ok to have that 2nd piece of pie

• Patterns for a tree of persistent data with multiple storage options?

  - by Robin Winslow

  I have a real-world problem which I'll try to abstract into an illustrative example. So imagine I have data objects in a tree, where parent objects can access children, and children can access parents: // Interfaces interface IParent<TChild> { List<TChild> Children; } interface IChild<TParent> { TParent Parent; } // Classes class Top : IParent<Middle> {} class Middle : IParent<Bottom>, IChild<Top> {} class Bottom : IChild<Middle> {} // Usage var top = new Top(); var middles = top.Children; // List<Middle> foreach (var middle in middles) { var bottoms = middle.Children; // List<Bottom> foreach (var bottom in bottoms) { var middle = bottom.Parent; // Access the parent var top = middle.Parent; // Access the grandparent } } All three data objects have properties that are persisted in two data stores (e.g. a database and a web service), and they need to reflect and synchronise with the stores. Some objects only request from the web service, some only write to it. Data Mapper My favourite pattern for data access is Data Mapper, because it completely separates the data objects themselves from the communication with the data store: class TopMapper { public Top FetchById(int id) { var top = new Top(DataStore.TopDataById(id)); top.Children = MiddleMapper.FetchForTop(Top); return Top; } } class MiddleMapper { public Middle FetchById(int id) { var middle = new Middle(DataStore.MiddleDataById(id)); middle.Parent = TopMapper.FetchForMiddle(middle); middle.Children = BottomMapper.FetchForMiddle(bottom); return middle; } } This way I can have one mapper per data store, and build the object from the mapper I want, and then save it back using the mapper I want. There is a circular reference here, but I guess that's not a problem because most languages can just store memory references to the objects, so there won't actually be infinite data. The problem with this is that every time I want to construct a new Top, Middle or Bottom, it needs to build the entire object tree within that object's Parent or Children property, with all the data store requests and memory usage that that entails. And in real life my tree is much bigger than the one represented here, so that's a problem. Requests in the object In this the objects request their Parents and Children themselves: class Middle { private List<Bottom> _children = null; // cache public List<Bottom> Children { get { _children = _children ?? BottomMapper.FetchForMiddle(this); return _children; } set { BottomMapper.UpdateForMiddle(this, value); _children = value; } } } I think this is an example of the repository pattern. Is that correct? This solution seems neat - the data only gets requested from the data store when you need it, and thereafter it's stored in the object if you want to request it again, avoiding a further request. However, I have two different data sources. There's a database, but there's also a web service, and I need to be able to create an object from the web service and save it back to the database and then request it again from the database and update the web service. This also makes me uneasy because the data objects themselves are no longer ignorant of the data source. We've introduced a new dependency, not to mention a circular dependency, making it harder to test. And the objects now mask their communication with the database. Other solutions Are there any other solutions which could take care of the multiple stores problem but also mean that I don't need to build / request all the data every time?

• Where to place web.xml outside WAR file for secure redirect?

  - by Silverhalide

  I am running Tomcat 7 and am deploying a bunch of applications delivered to me by a third party as WAR files. I'd like to force some of those apps to always use SSL. (All the "SSL" apps are in one service; other apps outside this discussion are in another service.) I've figured out how to use conf\web.xml to redirect apps from HTTP to HTTPS, but that applies to all applications hosted by Tomcat. I've also figured out how to put web.xml in an unpacked app's web-inf directory; that does the trick for that specific app, but runs the risk of being overwritten if our vendor gives us a new war file to deploy. I've also tried placing the web.xml file in various places under conf\service\host, or under appbase, but none seem to work. Is it possible to redirect some apps to SSL without forcing all apps to redirect, or to put the web.xml file inside the extracted WAR file? Here's my server.xml: <Service name="secure"> <Connector port="80" connectionTimeout="20000" redirectPort="443" URIEncoding="UTF-8" enableLookups="false" compression="on" protocol="org.apache.coyote.http11.Http11Protocol" compressableMimeType="text/html,text/xml,text/plain,text/javascript,application/json,text/css"/> <Connector port="443" URIEncoding="UTF-8" enableLookups="false" compression="on" protocol="org.apache.coyote.http11.Http11Protocol" compressableMimeType="text/html,text/xml,text/plain,text/javascript,application/json,text/css" scheme="https" secure="true" SSLEnabled="true" sslProtocol="TLS" keystoreFile="..." keystorePass="..." keystoreType="PKCS12" truststoreFile="..." truststorePass="..." truststoreType="JKS" clientAuth="false" ciphers="SSL_RSA_WITH_RC4_128_MD5,SSL_RSA_WITH_RC4_128_SHA,TLS_RSA_WITH_AES_128_CBC_SHA,TLS_DHE_RSA_WITH_AES_128_CBC_SHA,TLS_DHE_DSS_WITH_AES_128_CBC_SHA,SSL_RSA_WITH_AES_128_CBC_SHA"/> <Engine name="secure" defaultHost="localhost"> <Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="UserDatabase"/> <Host name="localhost" appBase="webapps" unpackWARs="false" autoDeploy="true" xmlValidation="false" xmlNamespaceAware="false"> </Host> </Engine> </Service> <Service name="mutual-secure"> ... </Service> The content of the web.xml files I'm playing with is: <web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0" metadata-complete="true"> <security-constraint> <web-resource-collection> <web-resource-name>All applications</web-resource-name> <url-pattern>/*</url-pattern> </web-resource-collection> <user-data-constraint> <description>Redirect all requests to HTTPS</description> <transport-guarantee>CONFIDENTIAL</transport-guarantee> </user-data-constraint> </security-constraint> </web-app> (For conf\web.xml the security-constraint is added just before the end of the existing file, rather than create a new file.) My webapps directory (currently) contains only the WAR files.

Error code = 0x8007000b In MS connect this is reported as a bug but MS is unable to reproduce the problem altough when you search the fora I'm not the only one with this problem. So any help is appreciated.

• WCF: Manually configuring Binding and Endpoint causes SerciveChannel Faulted State

  - by Matthias

  Hi there, I've created a ComVisible assembly to be used in a classic-asp application. The assembly should act as a wcf client and connect to a wcf service host (inside a windows service) on the same machine using named pipes. The wcf service host works fine with other clients, so the problem must be within this assembly. In order to get things work I added a service reference to the ComVisible assembly and proxy classes and the corresponding app.config settings were generated for me. Everything fine so far except that the app config would not be recognized when doing an CreateObject with my assembly in the asp code. I went and tried to hardcode (just for testing) the Binding and Endpoint and pass those two to the constructor of my ClientBase derived proxy using this code: private NetNamedPipeBinding clientBinding = null; private EndpointAddress clientAddress = null; clientBinding = new NetNamedPipeBinding(); clientBinding.OpenTimeout = new TimeSpan(0, 1, 0); clientBinding.CloseTimeout = new TimeSpan(0, 0, 10); clientBinding.ReceiveTimeout = new TimeSpan(0, 2, 0); clientBinding.SendTimeout = new TimeSpan(0, 1, 0); clientBinding.TransactionFlow = false; clientBinding.TransferMode = TransferMode.Buffered; clientBinding.TransactionProtocol = TransactionProtocol.OleTransactions; clientBinding.HostNameComparisonMode = HostNameComparisonMode.StrongWildcard; clientBinding.MaxBufferPoolSize = 524288; clientBinding.MaxBufferSize = 65536; clientBinding.MaxConnections = 10; clientBinding.MaxReceivedMessageSize = 65536; clientAddress = new EndpointAddress("net.pipe://MyService/"); MyServiceClient client = new MyServiceClient(clientBinding, clientAddress); client.Open(); // do something with the client client.Close(); But this causes the following error: The communication object, System.ServiceModel.Channels.ServiceChannel, cannot be used for communication because it is in the faulted state. The environment is .Net Framework 3.5 / C#. What am I missing here?

• .NET remoting exception: Exception in the Socket#33711845::DoBind - Only one usage of each socket ad

  Hi All, I'm attempting to setup a simple remoting windows service and getting the following error when starting the service: "System.Net.Sockets Error: 0 : [4180] Exception in the Socket#33711845::DoBind - Only one usage of each socket address (protocol/network address/port) is normally permitted System.Net.Sockets Verbose: 0 : [4180] ExclusiveTcpListener#4032828::Start() System.Net.Sockets Verbose: 0 : [4180] Socket#33711845::Bind(0:9998#9998) System.Net.Sockets Error: 0 : [4180] Exception in the Socket#33711845::DoBind - Only one usage of each socket address (protocol/network address/port) is normally permitted ". In the windows service application I have the following code in the "OnStart" method - the error occurs when registering the Channel - ChannelServices.RegisterChannel(tcpPipe, true); As far as I can tell there are no other processes using port 9998 ...

• Parse.com REST API in Java (NOT Android)

  - by Orange Peel

  I am trying to use the Parse.com REST API in Java. I have gone through the 4 solutions given here https://parse.com/docs/api_libraries and have selected Parse4J. After importing the source into Netbeans, along with importing the following libraries: org.slf4j:slf4j-api:jar:1.6.1 org.apache.httpcomponents:httpclient:jar:4.3.2 org.apache.httpcomponents:httpcore:jar:4.3.1 org.json:json:jar:20131018 commons-codec:commons-codec:jar:1.9 junit:junit:jar:4.11 ch.qos.logback:logback-classic:jar:0.9.28 ch.qos.logback:logback-core:jar:0.9.28 I ran the example code from https://github.com/thiagolocatelli/parse4j Parse.initialize(APP_ID, APP_REST_API_ID); // I replaced these with mine ParseObject gameScore = new ParseObject("GameScore"); gameScore.put("score", 1337); gameScore.put("playerName", "Sean Plott"); gameScore.put("cheatMode", false); gameScore.save(); And I got that it was missing org.apache.commons.logging, so I downloaded that and imported it. Then I ran the code again and got Exception in thread "main" java.lang.NoSuchMethodError: org.slf4j.spi.LocationAwareLogger.log(Lorg/slf4j/Marker;Ljava/lang/String;ILjava/lang/String;Ljava/lang/Throwable;)V at org.apache.commons.logging.impl.SLF4JLocationAwareLog.debug(SLF4JLocationAwareLog.java:120) at org.apache.http.client.protocol.RequestAddCookies.process(RequestAddCookies.java:122) at org.apache.http.protocol.ImmutableHttpProcessor.process(ImmutableHttpProcessor.java:131) at org.apache.http.impl.execchain.ProtocolExec.execute(ProtocolExec.java:193) at org.apache.http.impl.execchain.RetryExec.execute(RetryExec.java:85) at org.apache.http.impl.execchain.RedirectExec.execute(RedirectExec.java:108) at org.apache.http.impl.client.InternalHttpClient.doExecute(InternalHttpClient.java:186) at org.apache.http.impl.client.CloseableHttpClient.execute(CloseableHttpClient.java:82) at org.apache.http.impl.client.CloseableHttpClient.execute(CloseableHttpClient.java:106) at org.apache.http.impl.client.CloseableHttpClient.execute(CloseableHttpClient.java:57) at org.parse4j.command.ParseCommand.perform(ParseCommand.java:44) at org.parse4j.ParseObject.save(ParseObject.java:450) I could probably fix this with another import, but I suppose then something else would pop up. I tried the other libraries with similar results, missing a bunch of libraries. Has anyone actually used REST API successfully in Java? If so, I would be grateful if you shared which library/s you used and anything else required to get it going successfully. I am using Netbeans. Thanks.

• WebSocket handshake with Ruby and EM::WebSocket::Server

• Self hosted WCF ServiceHost/WebServiceHost Concurrency/Peformance Design Options (.NET 3.5)

  - by Kyle

  So I'll be providing a few functions via a self hosted (in a WindowsService) WebServiceHost (not sure how to process HTTP GET/POST with ServiceHost), one of which may be called a large amount of the time. This function will also rely on a connection in the appdomain (hosted by the WindowsService so it can stay alive over multiple requests). I have the following concerns and would be oh so thankful for any input/thoughts/comments: Concurrent access - how does the WebServiceHost handle a bunch of concurrent requests. Are they queued and processes sequentially or are new instances of the contracts automagically created? WebServiceHost - WindowsService communication - I need some form of communication from the WebServiceHost to the hosting WindowsService for things like requesting a new session if one does not exist. Perhaps implementing a class which extends the WebServiceHost with events which the WindowsService subscribes to... (unless there is another way I can set off an event in the WindowsService when a request is made...) Multiple WebServiceHosts or Contracts - Would it give any real performance gain to be running multiple WebServiceHost instances in different threads (one per endpoint perhaps?) - A better understanding of the first point would probably help here. WSDL - I'm not sure why (probably just need to do more reading), but I'm not sure how to get the WebServiceHost base endpoint to respond with a WDSL document describing the available contract. Not required as all the operations will be done via GET requests which will not likely change, but it would be nice to have... That's about it for the moment ;) I've been reading a lot on WCF and wish I'd gotten into it long ago, but definitely still learning.

• Server socket programming in Android 1.5, most power efficient way?

  - by Antek

  Hello people, I am doing a project where I have too develop an application that listens for incoming events by a service. The device that has to listen too events is an Android phone with Android SDK 1.5 on it. Currently the services that call events only implement communication trough UDP or TCP sockets. I can solve my problem by setting up a ServerSocket, but i doubt that's the most power efficient way. This application will be running most of the time, with Wi-Fi on, and I'd like too reach an long battery duration. I've been looking for options on the internet for my question for a while but i couldn't get a real answer. I've got the following questions: What is the most efficient way too listen to incoming events? Should I make an ServerSocket? or what are my options? Are there any other implementations that are more power efficient? Ive been also thinking of implementing communication trough XMPP. Not sure if this is the best way. I'm not forced too an specific implementation. All suggestions are welcome! Thanks for the help, Antek
