  • Defining Discovery: Core Concepts

    - by Joe Lamantia
    Discovery tools have had a referencable working definition since at least 2001, when Ben Shneiderman published 'Inventing Discovery Tools: Combining Information Visualization with Data Mining'.  Dr. Shneiderman suggested the combination of the two distinct fields of data mining and information visualization could manifest as new category of tools for discovery, an understanding that remains essentially unaltered over ten years later.  An industry analyst report titled Visual Discovery Tools: Market Segmentation and Product Positioning from March of this year, for example, reads, "Visual discovery tools are designed for visual data exploration, analysis and lightweight data mining." Tools should follow from the activities people undertake (a foundational tenet of activity centered design), however, and Dr. Shneiderman does not in fact describe or define discovery activity or capability. As I read it, discovery is assumed to be the implied sum of the separate fields of visualization and data mining as they were then understood.  As a working definition that catalyzes a field of product prototyping, it's adequate in the short term.  In the long term, it makes the boundaries of discovery both derived and temporary, and leaves a substantial gap in the landscape of core concepts around discovery, making consensus on the nature of most aspects of discovery difficult or impossible to reach.  I think this definitional gap is a major reason that discovery is still an ambiguous product landscape. To help close that gap, I'm suggesting a few definitions of four core aspects of discovery.  These come out of our sustained research into discovery needs and practices, and have the goal of clarifying the relationship between discvoery and other analytical categories.  They are suggested, but should be internally coherent and consistent.   Discovery activity is: "Purposeful sense making activity that intends to arrive at new insights and understanding through exploration and analysis (and for these we have specific defintions as well) of all types and sources of data." Discovery capability is: "The ability of people and organizations to purposefully realize valuable insights that address the full spectrum of business questions and problems by engaging effectively with all types and sources of data." Discovery tools: "Enhance individual and organizational ability to realize novel insights by augmenting and accelerating human sense making to allow engagement with all types of data at all useful scales." Discovery environments: "Enable organizations to undertake effective discovery efforts for all business purposes and perspectives, in an empirical and cooperative fashion." Note: applicability to a world of Big data is assumed - thus the refs to all scales / types / sources - rather than stated explicitly.  I like that Big Data doesn't have to be written into this core set of definitions, b/c I think it's a transitional label - the new version of Web 2.0 - and goes away over time.

  • Dynamic Data Connections

    - by Tim Dexter
    I have had a long running email thread running between Dan and David over at Valspar and myself. They have built some impressive connectivity between their in house apps and BIP using web services. The crux of their problem has been that they have multiple databases that need the same report executed against them. Not such an unusual request as I have spoken to two customers in the last month with the same situation. Of course, you could create a report against each data connection and just run or call the appropriate report. Not too bad if you have two or three data connections but more than that and it becomes a maintenance nightmare having to update queries or layouts. Ideally you want to have just a single report definition on the BIP server and to dynamically set the connection to be used at runtime based on the user or system that the user is in. A quick bit of digging and help from Shinji on the development team and I had an answer. Rather embarassingly, the solution has been around since the Oct 2010 rollup patch last year. Still, I grabbed the latest Jan 2011 patch - check out Note 797057.1 for the latest available patches. Once installed, I used the best web service testing tool I have yet to come across - SoapUI. Just point it at the WSDL and you can check out the available services and their parameters and then test them too. The XML packet has a new dynamic data source entry. You can set you own custom JDBC connection or just specify an existing data source name thats defined on the server. <pub:runReport> <pub:reportRequest> <pub:attributeFormat>xml</pub:attributeFormat> <pub:attributeTemplate>0</pub:attributeTemplate> <pub:byPassCache>true</pub:byPassCache> <pub:dynamicDataSource> <pub:JDBCDataSource> <pub:JDBCDriverClass></pub:JDBCDriverClass> <pub:JDBCDriverType></pub:JDBCDriverType> <pub:JDBCPassword></pub:JDBCPassword> <pub:JDBCURL></pub:JDBCURL> <pub:JDBCUserName></pub:JDBCUserName> <pub:dataSourceName>Conn1</pub:dataSourceName> </pub:JDBCDataSource> </pub:dynamicDataSource> <pub:reportAbsolutePath>/Test/Employee Report/Employee Report.xdo</pub:reportAbsolutePath> </pub:reportRequest> <pub:userID>Administrator</pub:userID> <pub:password>Administrator</pub:password> </pub:runReport> So I have Conn1 and Conn2 defined that are connections to different databases. I can just flip the name, make the WS call and get the appropriate dataset in my report. Just as an example, here's my web service call java code. Just a case of bringing in the BIP java libs to my java project. publicReportServiceService = new PublicReportServiceService(); PublicReportService publicReportService = publicReportServiceService.getPublicReportService_v11(); String userID = "Administrator"; String password = "Administrator"; ReportRequest rr = new ReportRequest(); rr.setAttributeFormat("xml"); rr.setAttributeTemplate("1"); rr.setByPassCache(true); rr.setReportAbsolutePath("/Test/Employee Report/Employee Report.xdo"); rr.setReportOutputPath("c:\\temp\\output.xml"); BIPDataSource bipds = new BIPDataSource(); JDBCDataSource jds = new JDBCDataSource(); jds.setDataSourceName("Conn1"); bipds.setJDBCDataSource(jds); rr.setDynamicDataSource(bipds); try { publicReportService.runReport(rr, userID, password); } catch (InvalidParametersException e) { e.printStackTrace(); } catch (AccessDeniedException e) { e.printStackTrace(); } catch (OperationFailedException e) { e.printStackTrace(); } } Note, Im no java whiz kid or whizzy old bloke, at least not unless Ive had a coffee. JDeveloper has a nice feature where you point it at the WSDL and it creates everything to support your calling code for you. Couple of things to remember: 1. When you call the service, remember to set the bypass the cache option. Forget it and much scratching of your head and taking my name in vain will ensue. 2. My demo actually hit the same database but used two users, one accessed the base tables another views with the same name. For far too long I thought the connection swapping was not working. I was getting the same results for both users until I realized I was specifying the schema name for the table/view in my query e.g. select * from EMP.EMPLOYEES. So remember to have a generic query that will depend entirely on the connection. Its a neat feature if you want to be able to switch connections and only define a single report and call it remotely. Now if you want the connection to be set dynamically based on the user and the report run via the user interface, thats going to be more tricky ... need to think about that one!

  • Portal And Content - Content Integration - Best Practices

    - by Stefan Krantz
    Lately we have seen an increase in projects that have failed to either get user friendly content integration or non satisfactory performance. Our intention is to mitigate any knowledge gap that our previous post might have left you with, therefore this post will repeat some recommendation or reference back to old useful post. Moreover this post will help you understand ground up how to design, architect and implement business enabled, responsive and performing portals with complex requirements on business centric information publishing. Design the Information Model The key to successful portal deployments is Information modeling, it's a key task to understand the use case you designing for, therefore I have designed a set of question you need to ask yourself or your customer: Question: Who will own the content, IT or Business? Answer: BusinessQuestion: Who will publish the content, IT or Business? Answer: BusinessQuestion: Will there be multiple publishers? Answer: YesQuestion: Are the publishers computer scientist?Answer: NoQuestion: How often do the information changes, daily, weekly, monthly?Answer: Daily, weekly If your answers to the questions matches at least 2, we strongly recommend you design your content with following principles: Divide your pages in to logical sections, where each section is marked with its purpose Assign capabilities to each section, does it contain text, images, formatting and/or is it static and is populated through other contextual information Select editor/design element type WYSIWYG - Rich Text Plain Text - non-format text Image - Image object Static List - static list of formatted informationDynamic Data List - assembled information from multiple data files through CMIS query The result of such design map could look like following below examples: Based on the outcome of the required elements in the design column 3 from the left you will now simply design a data model in WebCenter Content - Site Studio by creating a Region Definition structure matching your design requirements.For more information on how to create a Region definition see following post: Region Definition Post - note see instruction 7 for details. Each region definition can now be used to instantiate data files, a data file will hold the actual data for each element in the region definition. Another way you can see this is to compare the region definition as an extension to the metadata model in WebCenter Content for each data file item. Design content templates With a solid dependable information model we can now proceed to template creation and page design, in this phase focuses on how to place the content sections from the region definition on the page via a Content Presenter template. Remember by creating content presenter templates you will leverage the latest and most integrated technology WebCenter has to offer. This phase is much easier since the you already have the information model and design wire-frames to base the logic on, however there is still few considerations to pay attention to: Base the template on ADF and make only necessary exceptions to markup when required Leverage ADF design components for Tabs, Accordions and other similar components, this way the design in the content published areas will comply with other design areas based on custom ADF taskflows There is no performance impact when using meta data or region definition based data All data access regardless of type, metadata or xml data it can be accessed via the Content Presenter - Node. See below for applied examples on how to access data Access metadata property from Document - #{node.propertyMap['myProp'].value}myProp in this example can be for instance (dDocName, dDocTitle, xComments or any other available metadata) Access element data from data file xml - #{node.propertyMap['[Region Definition Name]:[Element name]'].asTextHtml}Region Definition Name is the expect region definition that the current data file is instantiatingElement name is the element value you like to grab from the data file I recommend you read following  useful post on content template topic:CMIS queries and template creation - note see instruction 9 for detailsStatic List template rendering For more information on templates:Single Item Content TemplateMulti Item Content TemplateExpression Language Internationalization Considerations When integrating content assets via content presenter you by now probably understand that the content item/data file is wired to the page, what is also pretty common at this stage is that the content item/data file only support one language since its not practical or business friendly to mix that into a complex structure. Therefore you will be left with a very common dilemma that you will have to either build a complete new portal for each locale, which is not an good option! However with little bit of information modeling and clear naming convention this can be addressed. Basically you can simply make sure that all content item/data file are named with a predictable naming convention like "Content1_EN" for the English rendition and "Content1_ES" for the Spanish rendition. This way through simple none complex customizations you will be able to dynamically switch the actual content item/data file just before rendering. By following proposed approach above you not only enable a simple mechanism for internationalized content you also preserve the functionality in the content presenter to support business accessible run-time publishing of information on existing and new pages. I recommend you read following useful post on Internationalization topics:Internationalize with Content Presenter Integrate with Review & Approval processes Today the Review and approval functionality and configuration is based out of WebCenter Content - Criteria Workflows. Criteria Workflows uses the metadata of the checked in document to evaluate if the document is under any review/approval process. So for instance if a Criteria Workflow is configured to force any documents with Version = "2" or "higher" and Content Type is "Instructions", any matching content item version on check in will now enter the workflow before getting released for general access. Few things to consider when configuring Criteria Workflows: Make sure to not trigger on version one for Content Items that are Data Files - if you trigger on version 1 you will not only approve an empty document you will also have a content presenter pointing to a none existing document - since the document will only be available after successful completion of the workflow Approval workflows sometimes requires more complex criteria, the recommendation if that is the case is that the meta data triggering such criteria is automatically populated, this can be achieved through many approaches including Content Profiles Criteria workflows are configured and managed in WebCenter Content Administration Applets where you can configure one or more workflows. When you configured Criteria workflows the Content Presenter will support the editors with the approval process directly inline in the "Contribution mode" of the portal. In addition to approve/reject and details of the task, the content presenter natively support the user to view the current and future version of the change he/she is approving. See below for example: Architectural recommendation To support review&approval processes - minimize the amount of data files per page Each CMIS query can consume significant time depending on the complexity of the query - minimize the amount of CMIS queries per page Use Content Presenter Templates based on ADF - this way you minimize the design considerations and optimize the usage of caching Implement the page in as few Data files as possible - simplifies publishing process, increases performance and simplifies release process Named data file (node) or list of named nodes when integrating to pages increases performance vs. querying for data Named data file (node) or list of named nodes when integrating to pages enables business centric page creation and publishing and reduces the need for IT department interaction Summary Just because one architectural decision solves a business problem it doesn't mean its the right one, when designing portals all architecture has to be in harmony and not impacting each other. For instance the most technical complex solution is not always the best since it will most likely defeat the business accessibility, performance or both, therefore the best approach is to first design for simplicity that even a non-technical user can operate, after that consider the performance impact and final look at the technology challenges these brings and workaround them first with out-of-the-box features, after that design and develop functions to complement the short comings.

  • Enable Full Screen Mode in Media Center Without Trapping the Mouse

    - by DigitalGeekery
    If you have a dual monitor setup and use Windows Media Center, you’re probably aware that when WMC is in full screen mode, it traps the mouse so you can’t work on a second monitor. Here we look at how to solve the annoyance. The Maxifier is an application that allows you to open Media Center in full screen mode without restricting the mouse. It relieves the annoyance of WMC capturing your mouse on a dual monitor setup. Note: If you don’t have two monitors attached, most of The Maxifier’s functions won’t work. Installation and Use Download, extract, and install The Maxifier. (See the download link below) The Maxifier runs minimized in the system tray and you access the options by right-clicking on the icon. If Media Center is not already open, you can choose Start Media Center to start WMC on the main start screen. Or, choose one of the other selections to open another area of Media Center. By default, Maxifier opens Media Center in full screen mode on the secondary monitor. When Media Center is open in full screen mode, you’ll notice you can now freely move your mouse around your multi-monitor setup. When Media Center is open, you’ll see five additional options. The Fit Screen options simply fits Media Center to the full screen, but still show the Windows borders. Full screen options put WMC in full screen mode.   The Maxifier Options allow you to choose from the various start up options. Selecting Watch for Media Center starting will prompt Maxifier to open WMC to the main start page in full screen mode on the secondary monitor automatically, even if you open Media Center without using The Maxifier.  (You may need to restart for this to take effect) If you have more than 2 monitors, you can define on which monitor to open Media Center, and which monitor you consider to be the main screen.   You can also define a number of Hotkeys in The Maxifier settings. First, select the Enable Hotkeys checkbox. To create a Hotkey, click in the text field and then press the keys to use as the Hotkey. To remove a Hotkey, click in the field and press the Delete key.   Conclusion The Maxifier is a simple program that enables Media Center users to take full advantage of a multi-monitor workspace. It works with both Vista and Windows 7. Version 1.4 is a stable application for Vista, and Version 1.5b is a beta application for Windows 7. Looking for more Media Center tips and tweaks?

  • Solaris 11 pkg fix is my new friend

    - by user12611829
    While putting together some examples of the Solaris 11 Automated Installer (AI), I managed to really mess up my system, to the point where AI was completely unusable. This was my fault as a combination of unfortunate incidents left some remnants that were causing problems, so I tried to clean things up. Unsuccessfully. Perhaps that was a bad idea (OK, it was a terrible idea), but this is Solaris 11 and there are a few more tricks in the sysadmin toolbox. Here's what I did. # rm -rf /install/* # rm -rf /var/ai # installadm create-service -n solaris11-x86 --imagepath /install/solaris11-x86 \ -s [email protected] Warning: Service svc:/network/dns/multicast:default is not online.

  • BIP Debugging to a file

    - by Tim Dexter
    If you use the standalone server or with OBIEE and use OC4J as the web server. Have you ever taken a looksee at the console window (doc/xterm) that you use to start it. Ever turned on debugging to see masses of info flow by that window and want to capture it all? I have been debugging today and watched all that info fly by and on Windoze gets lost before you can see it! The BIP developers use the System.out.println() and System.err.println()methods in the BIP applications to generate debugging formation. Normally the output from these method calls go to the console where the OC4J process is started. However you can specify command line options when starting OC4J to direct the stdout and stderr output directly to files. The ?out and ?err parameters tell OC4J which file to direct the output to. All you need do is modify the oc4j.cmd file used to start BIP. I didnt get fancy and just plugged in the following to the file under the start section. I just modified the line: set CMDARGS=-config "%SERVER_XML%" -userThreads to set CMDARGS=-config "%SERVER_XML%" -out D:\BI\OracleBI\oc4j_bi\j2ee\home\log\oc4j.out -err D:\BI\OracleBI\oc4j_bi\j2ee\home\log\oc4j.err -userThreads Bounced the server and I now have a ballooning pair of debug files that I can pour over to my hearts content. The .out file appears to contain BIP only log info and the .err file, OBIEE messages. If you are using another web server to host BIP, just check out the user docs to find out how to get the log files to write. Note to self, remember to turn off the debug when Im done!

  • Doing Time Limited Flight Recordings Using Start Up Parameters

    - by Marcus Hirt
    Just like with the old JRockit Runtime Analyzer, it is possible to start up recordings using command line parameters to JRockit. The parameter is called -XX:StartFlightRecording in R28. Below is an example that starts a flight recording half a minute after the JVM has been started. The recording will last for a minute. The name when viewing the ongoing recordings will be MyRecording, and the resulting file will be written to C:\tmp\myrecording.jfr. The recording will use the settings in jre\lib\jfr\profile.jfs. -XX:StartFlightRecording=delay=30s,duration=60s,name=MyRecording,filename=C:\tmp\myrecording.jfr,settings=profile For more information, see the JRockit R28 command line parameter documentation.

  • OrbitFX: JavaFX 8 3D & NetBeans Platform in Space!

    - by Geertjan
    Here is a collection of screenshots from a proof of concept tool being developed by Nickolas Sabey and Sean Phillips from a.i. solutions. Before going further, read a great new article here written on java.net by Kevin Farnham, in light of the Duke's Choice Award (DCA) recently received at JavaOne 2013 by the a.i. solutions team. Here's Sean receiving the award on behalf of the a.i. solutions team, surrounded by the DCA selection committee and other officials: They won the DCA for helping facilitate and deploy the 2014 launch of NASA's Magnetospheric Multiscale mission, using JDK 7, the NetBeans Platform, and JavaFX to create the GEONS Ground Support System, helping reduce software development time by approximately 35%. The prototype tool that Nicklas and Sean are now working on uses JavaFX 3D with the NetBeans Platform and is nicknamed OrbitFX. Much of the early development is being done to experiment with different patterns, so that accuracy is currently not the goal. For example, you'll notice in the screenshots that the Earth is really close to the Sun, which is obviously not correct. The screenshots are generated using Java 8 build 111, together with NetBeans Platform 7.4. Inspired by various JavaOne demos using JavaFX 3D, Nick began development integrating them into their existing NetBeans Platform infrastructure. The 3D scene showing the Sun and Earth objects is all JavaFX 8 3D, demonstrating the use of Phong Material support, along with multiple light and camera objects. Each JavaFX component extends a JFXPanel type, so that each can easily be added to NetBeans Platform TopComponents. Right-clicking an item in the explorer view offers a context menu that animates and centers the 3D scene on the selected celestial body.  With each JavaFX scene component wrapped in a JFXPanel, they can easily be integrated into a NetBeans Platform Visual Library scene.  In this case, Nick and Sean are using an instance of their custom Slipstream PinGraphScene, which is an extension of the NetBeans Platform VMDGraphScene. Now, via the NetBeans Platform Visual Library, the OrbitFX celestial body viewer can be used in the same space as a WorldWind viewer, which is provided by a previously developed plugin. "This is a clear demonstration of the power of the NetBeans Platform as an application development framework," says Sean Phillips. "How else could you have so much rich application support placed literally side by side so easily?"

  • What Error Messages Reveal

    - by ultan o'broin
    I love this blog entry Usability doesn't mean UI Especially the part: Ask for a list of all error messages when you do your next vendor evaluation. You will learn more about the vendor's commitment to usability and product quality than you will fathom from a slick demo. Not so sure about the part about error messages not being "hip" or "glamorous" though. I know... I should get out more...:)

  • ADF Bounded Taskflow Activation

    - by Vijay Mohan
    hey guys, It's really been a while since I last blogged. Just came across a hard-to-debug scenario, so thought of sharing it for the benefit of ADF developers.I had a page fragment(jsff) wrapped inside a  bounded taskflow, for which the activation was conditional and was based on a requestScope property (be it a requestScope variable or a property coming from a requestScope bean). As soon as the taskflow activates and page renders the requestScope parameters life span ends. After that, when you raise an event inside the page (click of commandLink, moseHover, valueChange event etc) then for the first time the event gets fired but it fails to affect the change in the page, moreover, for the subsequent times the event itself doesn't get fired. Any guesses as to what could be the culprit..?I guess, I already gave the reason in the initial paragraph. For the first time when the event gets fired, the fwk sees that the page is already lying in inactivate state, so it fails to affect the change and for subsequent times it doesn't even fire the event because it already knew that the page/region is inactive. So, in such a scenario we must use either a pageFlowScope property or transientVO property which could exist till the page's life span.

  • Is Master Data Management CRM's Secret Sauce?

    - by divya.malik
    This was the title of a recent blog entry by our colleagues in EMEA. Having a good master data management system enables organizations to get a unified, accurate and complete understanding of their customers. Gartner Group's John Radcliffe explains why MDM is destined to be at the heart of future CRM and social CRM projects. Experts are predicting big things for master data management (MDM) in the immediate future. While far from being a new kid on the block, its potential benefits at a time when organisations are drowning in data mean that it is in the right place at the right time. "MDM is not 'nice to have'," explains John Radcliffe, research vice president at Gartner. "If tackled in the right way it can provide near term business value that plays into an organisation's new focus on cost efficiencies, risk management and regulatory compliance, while supporting growth and future transformative strategies." The complete article can be found here.

  • Using the JRockit Flight Recorder as an In-Flight Black Box

    The new JRockit Flight Recorder has some very interesting properties. It can be used like the black box of an airplane, allowing users to go back in time and check what was happening around the time when something went wrong. Here is how to enable the default continuous recording in JRockit to allow for that use case. The flight recorder is on by default in JRockit R28, the problem is that there is no recording running by default. To configure JRockit to start with the default recording running, add the parameter: -XX:FlightRecorderOptions=defaultrecording=true That will enable a recording with recording ID 0. You can see that it has been started properly by choosing Show Recordings from the context menu in JRockit Mission Control.   You should see something similar to the picture below. Simply right click on the recording and select dump to dump information available in the flight recorder. You can select to dump data for a specific period of time or all data. For more information about the command line parameters available to control the Flight Recorder, see the JRockit documentation.

  • Java Developer Days India Trip Report

    - by reza_rahman
    October 21st through October 25th I spoke at Java Developer Days India. This was three separate but identical one-day events in the cities of Pune (October 21st), Chennai (October 24th) and Bangalore (October 25th). For those with some familiarity with India, other than Hyderabad these cities are India's IT powerhouses. The events were focused on Java EE. I delivered five sessions on Java EE 7, WebSocket, JAX-RS 2, JMS 2 and EclipeLink/NoSQL. The events went extremely well and was packed in all three cities. More details on the sessions and Java Developer Days India, including the slide decks, posted on my personal blog.

  • Iterative Conversion

    - by stuart ramage
    Question Received: I am toying with the idea of migrating the current information first and the remainder of the history at a later date. I have heard that the conversion tool copes with this, but haven't found any information on how it does. Answer: The Toolkit will support iterative conversions as long as the original master data key tables (the CK_* tables) are not cleared down from Staging (the already converted Transactional Data would need to be cleared down) and the Production instance being migrated into is actually Production (we have migrated into a pre-prod instance in the past and then unloaded this and loaded it into the real PROD instance, but this will not work for your situation. You need to be migrating directly into your intended environment). In this case the migration tool will still know all about the original keys and the generated keys for the primary objects (Account, SA, etc.) and as such it will be able to link the data converted as part of a second pass onto these entities. It should be noted that this may result in the original opening balances potentially being displayed with an incorrect value (if we are talking about Financial Transactions) and also that care will have to be taken to ensure that all related objects are aligned (eg. A Bill must have a set to bill segments, meter reads and a financial transactions, and these entities cannot exist independantly). It should also be noted that subsequent runs of the conversion tool would need to be 'trimmed' to ensure that they are only doing work on the objects affected. You would not want to revalidate and migrate all Person, Account, SA, SA/SP, SP and Premise details since this information has already been processed, but you would definitely want to run the affected transactional record validation and keygen processes. There is no real "hard-and-fast" rule around this processing since is it specific to each implmentations needs, but the majority of the effort required should be detailed in the Conversion Tool section of the online help (under Adminstration/ The Conversion Tool). The major rule is to ensure that you only run the steps and validation/keygen steps that you need and do not do a complete rerun for your subsequent conversion.

  • Pivotal Announces JSR-352 Compliance for Spring Batch

    - by reza_rahman
    Pivotal, the company currently funding development of the popular Spring Framework, recently announced JSR 352 (aka Batch Applications for the Java Platform) compliance for the Spring Batch project. More specifically, Spring Batch targets JSR-352 Java SE runtime compatibility rather than Java EE runtime compatibility. If you are surprised that APIs included in Java EE can pass TCKs targeted for Java SE, you should not be. Many other Java EE APIs target compatibility in Java SE environments such as JMS and JPA. You can read about Spring Batch's support for JSR-352 here as well as the Spring configuration to get JSR-352 working in Spring (typically a very low level implementation concern intended to be completely transparent to most JSR-352 users). JSR 352 is one of the few very encouraging cases of major active contribution to the Java EE standard from the Spring development team (the other major effort being Rod Johnson's co-leadership of JSR 330 along with Bob Lee). While IBM's Christopher Vignola led the spec and contributed IBM's years of highly mission critical batch processing experience from products like WebSphere Compute Grid and z/OS batch, the Spring team provided major influences to the API in particular for the chunk processing, listeners, splits and operational interfaces. The GlassFish team's own Mahesh Kannan also contributed, in particular by implementing much of the Java EE integration work for the reference implementation. This was an excellent example of multilateral engineering collaboration through the standards process. For many complex reasons it is not too hard to find evidence of less than amicable interaction between the Spring ecosystem and the Java EE standard over the years if one cares to dig deep enough. In reality most developers see Spring and Java EE as two sides of the same server-side Java coin. At the core Spring and Java EE ecosystems have always shared deep undercurrents of common user bases, bi-directional flows of ideas and perhaps genuine if not begrudging mutual respect. We can all hope for continued strength for both ecosystems and graceful high notes of collaboration via efforts like JSR 352.

  • Elevating Customer Experience through Enterprise Social Networking

    - by john.brunswick
    I am not sure about most people, but I really dislike automated call center routing systems. They are impersonal and convey a sense that the company I am dealing with does not see the value of providing customer service that increases positive perception of their brand. By the time I am connected with a live support representative I am actually more frustrated than before I originally dialed. Each time a company interacts with its customers or prospects there is an opportunity to enhance that relationship. Technical enablers like call center routing systems can be a double edged sword - providing process efficiencies, but removing the human context of some interactions that can build a lot of long term value and create substantial repeat business. Certain web systems, available through "chat with a representative" now links on some web sites, provide a quick and easy way to get in touch with someone and cut down on help desk calls, but miss the opportunity to deliver an even more personal experience to customers and prospects. As more and more users head to the web for self-service and product information, the quality of this interaction becomes critical to supporting a company's brand image and viability. It takes very little effort to go a step further and elevate customer experience, without adding significant cost through social enterprise software technologies. Enterprise Social Networking Social networking technologies have slowly gained footholds in the enterprise, evolving from something that people may have been simply curious about, to tools that have started to provide tangible value in the enterprise. Much like instant messaging, once considered a toy in the enterprise, expertise search, blogs as communications tools, wikis for tacit knowledge sharing are all seeing adoption in a way that is directly applicable to the business and quickly adding value. So where does social networking come in when trying to enhance customer experience?

Verizon Wireless built the first wide-area wireless broadband network and delivered the first wireless consumer 3G multimedia service in the US, and offers global voice and data services in more than 200 destinations around the world. To support 4.2 million daily wireless transactions and 493,000 calls and emails transactions produced by 94.2 million retail customers, Verizon Wireless employs over 78,000 employees with area headquarters across the United States. The Business Challenge Seeing the stupendous rise in social media, video streaming, live broadcasting…etc which redefined the scope of technology, Verizon Wireless, as a technology savvy company, wanted to provide a platform to its employees where they could network socially, view and host microsites, stream live videos, blog and provide the latest news. The IT team at Verizon Wireless had abundant experience with various technology platforms to support the huge number of applications in the company. However, open-source products weren’t yet widely used in the organization and the team had the ambition to adopt such technologies and see if the architecture could meet Verizon Wireless’ rigid requirements. After evaluating a few solutions, the IT team decided to use the LAMP stack for Vzweb, its mission-critical, 24x7 employee portal, with Drupal as the front end and MySQL on Linux as the backend, and for a few other internal websites also on MySQL. The MySQL Solution Verizon Wireless started to support its employee portal, Vzweb, its online streaming website, Vztube, and internal wiki pages, Vzwiki, with MySQL 5.1 in 2010. Vzweb is the main internal communication channel for Verizon Wireless, while Vztube hosts important company-wide webcasts regularly for executive-level announcements, so both channels have to be live and accessible all the time for its 78,000 employees across the United States. However during the initial deployment of the MySQL based Intranet, the application experienced performance issues. High connection spikes occurred causing slow user response time, and the IT team applied workarounds to continue the service. A number of key performance indexes (KPI) for the infrastructure were identified and the operational framework redesigned to support a more robust website and conform to the 99.985% uptime SLA (Service-Level Agreement). The MySQL DBA team made a series of upgrades in MySQL: Step 1: Moved from MyISAM to InnoDB storage engine in 2010 Step 2: Upgraded to the latest MySQL 5.1.54 release in 2010 Step 3: Upgraded from MySQL 5.1 to the latest GA release MySQL 5.5 in 2011, and leveraging MySQL Thread Pool as part of MySQL Enterprise Edition to scale better After making those changes, the team saw a much better response time during high concurrency use cases, and achieved an amazing performance improvement of 1400%! In January 2011, Verizon CEO, Ivan Seidenberg, announced the iPhone launch during the opening keynote at Consumer Electronic Show (CES) in Las Vegas, and that presentation was streamed live to its 78,000 employees. The event was broadcasted flawlessly with MySQL as the database. Later in 2011, Hurricane Irene attacked the East Coast of United States and caused major life and financial damages. During the hurricane, the team directed more traffic to its west coast data center to avoid potential infrastructure damage in the East Coast. Such transition was executed smoothly and even though the geographical distance became longer for the East Coast users, there was no impact in the performance of Vzweb and Vztube, and the SLA goal was achieved. “MySQL is the key component of Verizon Wireless’ mission-critical employee portal application,” said Shivinder Singh, senior DBA at Verizon Wireless. “We achieved 1400% performance improvement by moving from the MyISAM storage engine to InnoDB, upgrading to the latest GA release MySQL 5.5, and using the MySQL Thread Pool to support high concurrent user connections. MySQL has become part of our IT infrastructure, on which potentially more future applications will be built.” To learn more about MySQL Enterprise Edition, Get our Product Guide.

  • Questions, Knowledge Checks and Assessments

    - by ted.henson
    Questions should be used to reinforce concepts throughout the title. You have the option to include questions in the course, in assessments, in Knowledge Checks, or in any combination. Questions are required for creating knowledge checks and assessments. It is important to remember that questions that are not in assessments are not tracked. Be sure to structure your outline so that questions are added to the appropriate assignable unit. I usually recommend that questions appear directly below their relative section. This serves two purposes. First, it helps ensure that the related content and question stay relative to one another. Secondly, it ensures that when the "link to subject" option is used it will relate back to the relative content. Knowledge checks are created using the questions that have been added to the related assignable unit. Use Knowledge Checks to give users an additional opportunity to review what they have learned. Knowledge Check allows users to check their own knowledge without being tracked or scored. Many users like having this self check option, especially if they know they are going to be tested later. Each assignable unit can have its own Knowledge Check. Assessments provide a way to measure knowledge or understanding of the course material. The results of each assessment are scored and tracked. Assessments are created using the questions that have been added to the relative assignable unit(s). Each assignable unit, including the Title AU, can have multiple assessments. Consider how your knowledge paths will be structured when planning your assessments. For instance, you can create a multiple-activity knowledge path, with multiple assessments from the same title or assignable unit. Also remember, in Manager an assessment can be either a pre or post assessment. Pre-assessments allow the student to discover what is already known in a specific topic or subject and important if the personal course feature is being used. Post-assessments allow you test the student knowledge or understanding after completing the material.
