  • VOTE by 20 June for OpenWorld Talk on OWB with Non-Oracle Sources

    - by antonio romero
    OWB/ODI Linkedin Group member Suraj Bang has offered a topic through OpenWorld 2010 Suggest-a-Session at Oracle Mix: Extend ETL to Heterogeneous and Unstructured Data Sources with OWB 11gR2 To vote for this talk to appear, click through to: http://bit.ly/owb_km_openworld and click on the "Vote" button. Abstract follows: Beyond basic Oracle-to-Oracle ETL, data warehousing customers need to integrate data from multiple data sources spanning multiple database vendors, file formats(csv, xml, html) and unstructured data sources like pdf's and log files. This session describes experiences extending OWB 11gR2 to extract data from Postgres, SQL Server, MySQL and Sybase, PDF documents, and more for a major banking client's data warehousing project supporting IT operations. This included metadata extraction, custom knowledge module-based ETL and replacing ad-hoc perl and java extraction code with a manageable ETL solution built on OWB's extensible plaform. Note: You must vote for at least two other talks for your vote to count, so if you haven’t already picked your three, also consider: Case Study: Real-Time data warehousing and fraud detection with Oracle 11gR2.

  • Display root node of Hierarchical Tree using ADF - EJB DC

    - by arul.wilson(at)oracle.com
    Displaying Employee (HR schema) records in Hierarchical Tree can be achieved in ADF-BC by creating custom VO and a Viewlink for displaying root node. This can be more easily done using  EJB-DC by just introducing a NamedQuery to get the root node.Here you go to get this scenario working.Create DB connection based on HR schema.Create Entity Bean from Employees Table.Add custom NamedQuery to Employees.java bean, this named query is responsible for fetching the root node (King in this example). @NamedQueries({  @NamedQuery(name = "Employees.findAll", query = "select o from Employees o"),  @NamedQuery(name = "Employees.findRootEmp", query = "select p from Employees p where p.employees is null")}) Create Stateless Session Bean and expose the Named Queries through the Session Facade.Create Datacontrol from SessionBean local interface.Create jspx page in ViewController project.Drop employeesFindRootEmp from Data Controls Palette as ADF Tree.Add employeesList as Tree level rule.Run page to see the hierarchical tree with root node as 'King'

  • Starting Spring Lineup

    - by onefloridacoder
    This morning I finished removing all VS2008 related frameworks and installed items related to VS2010 based on posts around the community.  Here’s what I started with on my dev laptop, the config for my laptop:  HP Pavilion dv6  Win7 64-bit 4Gb RAM Installed Developer Tools and Frameworks: Sync 2.0 SDK Visual Studio 2010 Pex Power Tools Enterprise Library 5.0 SQL Server 2008 Developer Edition Visual Studio 2008 Ultimate Expression Blend 4 RC Team Foundation Server 2010 Team Foundation Server 2010 SDK   The only item I did not reinstall on top of VS2010 was ReSharper 4.5 only because I read mixed reviews on the dev experience.  At this point I really just want to get use to the new(er) IDEs without adding any confusion to my dev machine.  I’ll level off my desire for early adoption at Blend, EntLib 5.0, and Pex - I’m also interested in the Moles integration as well.   Something else I didn’t have to install was my IDE theme which was left behind in my user folder was merged during installation – afterwards it was nice to see once the dust settled.

  • Five Things Learned at the BSR Conference in San Francisco on Nov 2nd-4th

    - by Evelyn Neumayr
    The BSR Conference 2011—“Redefining Leadership”—held from Nov 2nd to Nov 4th in San Francisco, with Oracle as one of the main sponsors, saw senior business executives, civil society representatives, and other experts from around the world gathering to share strategies and insights on the future of sustainability. The general conference sessions kicked off on November 2nd with a plenary address by former U.S. Vice President Al Gore. Other sessions were presented by CEOs of the caliber of Carl Bass (Autodesk), Brian Dunn (Best Buy), Carlos Brito (Anheuser-Busch InBev) and Ofra Strauss (Strauss Group). Here are five key highlights from the conference: 1.      The main leadership challenge is integrating sustainability into core business functions and overcoming short-termism. The “BSR GlobeScan State of Sustainable Business Poll 2011” - a survey of nearly 500 business leaders from 300 member companies - shows that 84% of respondents are optimistic that global businesses will embrace CSR/sustainability as part of their core strategies and operations in the next five years but consider integrating sustainability into their core business functions the key challenge. It is still difficult for many companies that are committed to the sustainability agenda to find investors that understand the long-term implications and as Al Gore said “Many companies are given the signal by the investors that it is the short term results that matter and that is a terribly debilitating force in the market.” 2.      Companies are required to address increasing compliance requirements and transparency in their supply chain, especially in relation with conflict minerals legislation and water management. The Dodd-Frank legislation, OECD guidelines, and the upcoming Securities and Exchange Commission (SEC) rules require companies to monitor upstream the sourcing of tin, tantalum, tungsten, and gold, but given the complexity of this issue companies need to collaborate and partner with peer companies in their industry as well as in other industries to understand how to address conflict minerals in their supply chains. The Institute of Public and Environmental Affairs’ (IPE) China Water Pollution Map enables the public to access thousands of environmental quality, discharge, and infraction records released by various government agencies. Empowered with this information, the public has the opportunity to place greater pressure on polluting companies to comply with environmental standards and create solutions to improve their performance. 3.      A new standard for reporting on supply chain greenhouse gas emissions is available. The New “Scope 3” Supply Chain Greenhouse Gas Inventory Standard, released on October 4th 2011, is the only international greenhouse gas emissions standard that accounts for the full lifecycle of a company’s products. It provides a framework for companies to account for indirect emissions outside of energy use, such as transportation, manufacturing, and distribution, and it incorporates both upstream and downstream impacts of a product. With key investors now listing supplier vulnerability to rising energy prices and disruptions of service as a key concern, greenhouse gas (GHG) management isn’t just for leading companies but a necessity for any business. 4.      Environmental, social, and corporate governance (ESG) reporting is becoming increasingly important to investors and other stakeholders. While European investors have traditionally driven the ESG agenda, U.S. investors are increasingly including ESG data in their analyses. This trend will likely increase as stakeholders continue to demand that an ESG lens be applied to their investments. Investors are increasingly looking to partner on sustainability, as they see the benefits of ESG providing significant returns on investment. 5.      Software companies are offering an increasing variety of solutions to help drive changes and measure performance internally, in supply chains, and across peer companies. The significant challenge is how to integrate different software systems to facilitate decision-making based on a holistic understanding of trade-offs. Jon Chorley, Chief Sustainability Officer and Vice President, Supply Chain Management Product Strategy at Oracle was a panelist in the “Trends in Sustainability Software” session and commented that, “How we think about our business decisions really comes down to how we think about cost. And as long as we don’t assign a cost to things that have an environmental impact or social impact, then we make decisions based on incomplete information. If we could include that in the process that determines ‘Is this product profitable? we would then have a much better decision.” For more information on BSR visit www.brs.org. You can also view highlights of the plenary session at http://www.bsr.org/en/bsr-conference/session-summaries/2011. Oracle is proud to be a sponsor of this BSR conference.

  • Import images from camera in KDE with particular directory structure

    - by Sergey
    I have been using f-spot for a few years to manage my photo archive, which is about 50K images at the moment. With the development of f-spot slowing down in the recent years and me switching to KDE, I'm looking at using DigiKam, which seems to be very nice and packed with features beyond my wildest hopes :) One thing I'm missing though is the way f-spot was importing the images: it was creating subdirectories based on the image's shooting date: $HOME/Photos/2011/11/12/IMG_1234.jpg $HOME/Photos/2011/11/13/IMG_1235.jpg $HOME/Photos/2011/11/13/IMG_1236.jpg I don't seem to be able to find a way to make DigiKam to behave like this - although it has some settings to change the image filename according to some mask which may include shooting date, I see now way to tell it to create sub-directories. Is there a way to make DigiKam to behave like this? Or, alternatively, what is a good program to import images from a camera and save them on disk in subdirectories according to their shooting date?

  • What is a good site to use for scheduling 20+ developers and 10 projects? (resource planning) [closed]

    - by b-ryce
    I have around 20 developers and 10 or so active projects. Then I get asked if my team can take on more work, and who is going to free up when. Currently we are using a spreadsheet to keep track :( I've been digging around for a few hours and haven't found anything that meets my requirements, which are: Web based Schedule a developer's time over a period of days/weeks/months Be able to see at a glance which developer has extra capacity Quickly see when the group could take on another large project I don't mind paying for the software (It does NOT need to be free) Two projects which look close are http://www.ganttic.com/tour and http://resourceguruapp.com/ What else are people using? Anyone have the perfect solution

  • PeopleSoft at Alliance 2012 Executive Forum

    - by John Webb
    Guest Posting From Rebekah Jackson This week I jointed over 4,800 Higher Ed and Public Sector customers and partners in Nashville at our annual Alliance conference.   I got lost easily in the hallways of the sprawling Gaylord Opryland Hotel. I carried the resort map with me, and I would still stand for several minutes at a very confusing junction, studying the map and the signage on the walls. Hallways led off in many directions, some with elevators going down here and stairs going up there. When I took a wrong turn I would instantly feel stuck, lose my bearings, and occasionally even have to send out a call for help.    It strikes me that the theme for the Executive Forum this year outlines a less tangible but equally disorienting set of challenges that our higher education customer’s CIOs are facing: Making Decisions at the Intersection of Business Value, Strategic Investment, and Enterprise Technology. The forces acting upon higher education institutions today are not neat, straight-forward decision points, where one can glance to the right, glance to the left, and then quickly choose the best course of action. The operational, technological, and strategic factors that must be considered are complex, interrelated, messy…and the stakes are high. Michael Horn, co-author of “Disrupting Class: How Disruptive Innovation Will Change the Way the World Learns”, set the tone for the day. He introduced the model of disruptive innovation, which grew out of the research he and his colleagues have done on ‘Why Successful Organizations Fail’. Highly simplified, the pattern he shared is that things start out decentralized, take a leap to extreme centralization, and then experience progressive decentralization. Using computers as an example, we started with a slide rule, then developed the computer which centralized in the form of mainframes, and gradually decentralized to mini-computers, desktop computers, laptops, and now mobile devices. According to Michael, you have more computing power in your cell phone than existed on the planet 60 years ago, or was on the first rocket that went to the moon. Applying this pattern to Higher Education means the introduction of expensive and prestigious private universities, followed by the advent of state schools, then by community colleges, and now online education. Michael shared statistics that indicate 50% of students will be taking at least one on line course by 2014…and by some measures, that’s already the case today. The implication is that technology moves from being the backbone of the campus, the IT department’s domain, and pushes into the academic core of the institution. Innovative programs are underway at many schools like Bellevue and BYU Idaho, joined by startups and disruptive new players like the Khan Academy.   This presents both threat and opportunity for higher education institutions, and means that IT decisions cannot afford to be disconnected from the institution’s strategic plan. Subsequent sessions explored this theme.    Theo Bosnak, from Attain, discussed the model they use for assessing the complete picture of an institution’s financial health. Compounding the issue are the dramatic trends occurring in technology and the vendors that provide it. Ovum analyst Nicole Engelbert, shared her insights next and suggested that incremental changes are no longer an option, instead fundamental changes are affecting the landscape of enterprise technology in higher ed.    Nicole closed with her recommendation that institutions focus on the trends in higher education with an eye towards the strategic requirements and business value first. Technology then is the enabler.   The last presentation of the day was from Tom Fisher, Sr. Vice President of Cloud Services at Oracle. Tom runs the delivery arm of the Cloud Services group, and shared his thoughts candidly about his experiences with cloud deployments as well as key issues around managing costs and security in cloud deployments. Okay, we’ve covered a lot of ground at this point, from financials planning, business strategy, and cloud computing, with the possibility that half of the institutions in the US might not be around in their current form 10 years from now. Did I forget to mention that was raised in the morning session? Seems a little hard to believe, and yet Michael Horn made a compelling point. Apparently 100 years ago, 8 of the top 10 education institutions in the world were German. Today, the leading German school is ranked somewhere in the 40’s or 50’s. What will the landscape be 100 years from now? Will there be an institution from China, India, or Brazil in the top 10? As Nicole suggested, maybe US parents will be sending their children to schools overseas much sooner, faced with the ever-increasing costs of a US based education. Will corporations begin to view skill-based certification from an online provider as a viable alternative to a 4 year degree from an accredited institution, fundamentally altering the education industry as we know it?

  • Reverse horizontal and vertical for a HTML table

    - by porton
    There is a two-dimensional array describing a HTML table. Each element of the array consists of: the cell content rowspan colspan Every row of this two dimensional array corresponds to <td> cells of a <tr> of the table which my software should generate. I need to "reverse" the array (interchange vertical and horizontal direction). Insofar I considered algorithm based on this idea: make a rectangular matrix of the size of the table and store in every element of this matrix the corresponding index of the element of the above mentioned array. (Note that two elements of the matrix may be identical due rowspan/colspan.) Then I could use this matrix to calculate rowspan/colspan for the inverted table. But this idea seems bad for me. Any other algorithms? Note that I program in PHP.

  • Mysql ndb cluster - node restart.

    - by Arafat
    Hi guys! I just setup a mysql cluster on a fairly decent baby (IBM x3650 M3) with 24GB memory, xeon 6core, SAS 6Gbps HDD. Running Debian Lenny 5. 64bits. Ndb version is 7.1.9a. Our database size on MyISAM is around 3.2 GB. Ndb_size estimation is 58GB for ndbengine. A little info about my database is as follows. 150 common tables for global purpose. 130 tables for each clients. So it goes like this, 130 x 115(clients) = 14950 tables. Is it normal or usual to have 14000 tables on one database? The reasons why we did this was, Easy maintenance and per client based customization. Now, the problem is, ndb cluster can only support, 20320 tables. But it can support 5,000,000,000 rows in one table if I'm not wrong. My real head ache is my cluster data node takes less than two minutes to startup with out any data. But as soon as convert my tables into ndb, that too only 2000 tables, data node takes at least 30 to 40 mins to start up. Is it normal? If I convertt all my tables into ndb, will it take even longer? Or let's say if consolidate my 14000 table's data into one, which is 130 tables, will it help? Or is there anything idiotically wrong which I'm doing? I'll attach my config.ini file soon. here's the simple overview of my config Datamemory = 14G Indexmemory = 3GB Maxnooftable = 14000 Maxnoofattributes = 78000 I'm just testing these values with 2000 tables first. Please advise, how to increase the start up speed. Please point out where I'm going wrong. Thanks in advance guys!

  • Make isolinux 4.0.3 chainload itself in VMWare

    - by chainloader
    I have a bootable iso which boots into isolinux 4.0.3 and I want to make it chainload itself (my actual goal is to chainload isolinux.bin v4.0.1-debian, which should start up the Ubuntu10.10 Live CD, but for now I just want to make it chainload itself). I can't get isolinux to chainload any isolinux.bin, no matter what version. It either freezes or shows a "checksum error" message. I'm using VMWare to test the iso. Things I have tried: .com32 /boot/isolinux/chain.c32 /boot/isolinux/isolinux-debug.bin (chainload self) this shows Loading the boot file... Booting...

  • SSIS - The expression cannot be parsed because it contains invalid elements at the location specifie

    - by simonsabin
    If you get the following error when trying to write an expression there is an easy solution Attempt to parse the expression "@[User::FilePath] + "\" + @[User::FileName] + ".raw"" failed.  The token "." at line number "1", character number "<some position>" was not recognized. The expression cannot be parsed because it contains invalid elements at the location specified. The SSIS expression language is a C based language and the \ is a token, this means you have to escape it with another one. i.e "\" becomes "\\", unlike C# you can't prefix the string with a @, you have to use the escaping route. In summary when ever you want to use \ you need to use two \\

  • Redering performance in FlasCC + UDK when compared to Stage3d and UDK on Windows?

    - by Arthur Wulf White
    http://gaming.adobe.com/technologies/flascc/ Developers can now access UDK for browser applications. Does this mean greater performance than using a Stage3D engine (Away3D 4) and how much of a noticeable difference in performance would it make in rendering speeds? Is there any benchmark you could propose that would allow to compare them fairly? I am asking this to help myself understand the consequences in performance for deciding to use UDK in a browser based game. I would also like to know how it compares with UDK running natively in Windows? I am not asking which technology to use or which is better. Only interested in the optimizing rendering speed in a 3d browser game with flash.

  • JustMock and Moles A short overview for TDD alpha geeks

    People have been lurking near my house, asking me to write something about Moles and JustMock, so Ill try to be as objective as possible, taking in the fact that I work at Typemock. If I were NOT working at Typemock Id write: JustMock JustMock tries to be Typemock at so many levels its not even funny. Technically they work the same and the API almost looks like its a search and replace work based on the Isolator API (awesome compliment!), but JustMock still has too many growing pains and bugs...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • howto configure mod_proxy for apache2, jetty

    - by Kaustubh P
    Hello, This is how I have setup my environment, atm. An apache2 instance on port 80. Jetty instance on the same server, on port 8090. Use-Case: When I visit foo.com, I should see the webapp, which is hosted on jetty, port 8090. If I put foo.com/blog, I should see the wordpress blog, which is hosted on apache. (I read howtos on the web, and installed it using AMP.) Below are my various configuration files: /etc/apache2/mods-enabled/proxy.conf: ProxyPass / http://foo.com:8090/ << this is the jetty server ProxyPass /blog http://foo.com/blog ProxyRequests On ProxyVia On <Proxy *> Order deny,allow Allow from all </Proxy> ProxyPreserveHost On ProxyStatus On /etc/apache2/httpd.conf: LoadModule proxy_module /usr/lib/apache2/modules/mod_proxy.so LoadModule proxy_balancer_module /usr/lib/apache2/modules/mod_proxy_balancer.so LoadModule proxy_http_module /usr/lib/apache2/modules/mod_proxy_http.so LoadModule proxy_ajp_module /usr/lib/apache2/modules/mod_proxy_ajp.so I have not created any other files, in sites-available or sites-enabled. Current situation: If I goto foo.com, I see the webapp. If I goto foo.com/blog, I see a HTTP ERROR 404 Problem accessing /errors/404.html. Reason: NOT_FOUND powered by jetty:// If I comment out the first ProxyPass line, then on foo.com, I only see the homepage, without CSS applied, ie, only text.. .. and going to foo.com/blog gives me a this error: The proxy server received an invalid response from an upstream server. The proxy server could not handle the request GET /blog. Reason: Error reading from remote server I also cannot access /phpmyadmin, giving the same 404 NOT_FOUND error as above. I am running Debian squeeze on an Amazon EC2 Instance. Question: Where am I going wrong? What changes should I make in the proxy.conf (or another conf files) to be able to visit the blog?

  • Do I need to know servlets and JSP to learn spring or hibernate or any other java web frameworks?

    - by KyelJmD
    I've been asking a lot of people where to start learning java web development, I already know core java (Threading,Generics,Collections, a little experience with (JDBC)) but I do not know JSPs and servlets. I did my fair share of development with several web based applications using PHP for server-side and HTML,CSS,Javascript,HTML5 for client side. Most people that I asked told me to jump right ahead to Hibernate while some told me that I do not need to learn servlets and jsps and I should immediately study the Spring framework. Is this true? do I not need to learn servlets and JSPs to learn hibernate or Spring? All of their answers confused me and now I am completely lost what to learn or study. I feel that if I skipped learning JSP and servlets I would missed a lot of important concepts that will surely help me in the future. So the question, do I need to have foundation/know servlets and JSP to learn spring or hibernate or any other java web frameworks.?

    I am looking for a best approach for designing a dynamic page. I want my users to be able to determine the position of set of controls to be loaded into a page. Should be able to add new controls or swap in and out new controls into an existing page. Eg: Portal based applications,iGoogle kind of websites I am afraid that I will be re-inventing the wheel if I go and create a portal structure for my web application. There are a couple of things in my mind to look into: Good third-party suites which can do the same Should I look into Silverlight RIA application? I have researched about the Infragistics and Telerik controls and the price is high for just a control like LayoutManager which I need. Any alternatives? What is the best approach for this kind of situation, to add to the list?

  • If Scheme is untyped, how can it have numbers and lists?

    - by Dokkat
    Scheme is said to be just an extension of the Untyped Lambda Calculus (correct me if I am wrong). If that is the case, how can it have Lists and Numbers? Those, to me, look like 2 base types. So I'd say Racket is actually an extension of the Simply Typed Lambda Calculus. No? Question: Is Scheme's type system actually based or more similar to Simply Typed or Untyped Lambda Calculus? In what ways does it differ from Untyped and or Simply Typed Lambda Calculus? (The same question is valid for "untyped" languages such as Python and JavaScript - all of which look like they have base types to me.)

  • Good online auction software

    - by Brett
    We are looking for some PHP-based auction software to start off with and I have have been scouring the net many times and am almost ready to purchase phpprobid as this seems to be the best and most feature rich of the lot; only bad things I have read is the lack of after-sales customer service. Others I have also looked at include: AJ Auction Software WeBid GuruScript Auction PHP Auction (enuuk). Many of them turn me off by having unprofessional sites which makes me think their software will be the same and be rubbish. Many also don't go into detail with the feature set like PHP Pro Bid does. So before we purchase PHP Pro Bid I was wondering if I missed something good? Thanks!

    I'm a developer who mostly does web stuff in ruby and C#.. I'd like to start tinkering with iOS and Mac development, Over the last few month i've been trying to get fluent in one set of key bindings (vi / vim because it just feels right).. I have the awesome ViEmu installed for visual studio on windows which gives me a ton of the vim awesomeness side by side with visual studio power toys.. Is there anything like this for xcode? I know i could set up MacVim as the default editor but i'm not too interested in this as it means losing all of xcode's cocoa awareness.. The other option of course would be to go for the lowest common denominator and switch to emacs (as the mac keybindings are based massively on emacs) but lets not think about that for too long. :P
