• xsltproc killed, out of memory

  - by David Parks

  I'm trying to split up a 13GB xml file into small ~50MB xml files with this XSLT style sheet. But this process kills xsltproc after I see it taking up over 1.7GB of memory (that's the total on the system). Is there any way to deal with huge XML files with xsltproc? Can I change my style sheet? Or should I use a different processor? Or am I just S.O.L.? <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0" xmlns:exsl="http://exslt.org/common" extension-element-prefixes="exsl" xmlns:fn="http://www.w3.org/2005/xpath-functions"> <xsl:output method="xml" indent="yes"/> <xsl:strip-space elements="*"/> <xsl:param name="block-size" select="75000"/> <xsl:template match="/"> <xsl:copy> <xsl:apply-templates select="mysqldump/database/table_data/row[position() mod $block-size = 1]" /> </xsl:copy> </xsl:template> <xsl:template match="row"> <exsl:document href="chunk-{position()}.xml"> <add> <xsl:for-each select=". | following-sibling::row[position() &lt; $block-size]" > <doc> <xsl:for-each select="field"> <field> <xsl:attribute name="name"><xsl:value-of select="./@name"/></xsl:attribute> <xsl:value-of select="."/> </field> <xsl:text>&#xa;</xsl:text> </xsl:for-each> </doc> </xsl:for-each> </add> </exsl:document> </xsl:template>

• Source of (programmer) inefficiency

  - by Daniel

  I am interested to gain a better insight about the possible reasons of personal inefficiency as programmers (and only in programming) due to – simply - our own errors (because we are humans – well, almost all of us). I am not interested in how much we are productive or in how many adjustements the customer asks for when the work is done, but where and how each of us spend that part of its time in tasks that are unproductive and there is no one to blame except ourselves. Excluding ego - feeding and / or self – gratification, what I am trying to get (for all of us) is: what are the common issues eating our time; insight on reasons for that issues; identify simple way for us, personally (not delegating actions to other or our organizations), to correct our own problems. Please, do not think in academic terms but aim at the opportunity to compare our daily experiences and understand what are and how we try to fix our personal deficiencies. If you are interested to respond to this post, please: integrate the list if you see something important (or obvious) missing; highlight or name honestly your first issue tellng the way you try to address and solve your issue acting on yourself and yourself only in a sort of "continuous quality improving" My criteria for accepting the answer is: choose the best solution (feasibility and utility) to fix one (or more) of the problems of the list. Of course, selecting an error is not a vote on our skills: maybe we are hyper professional programmers and we lose ten minutes only every year or we are terribly inefficient, losing a couple of days a week: reasons for inefficiency could be really the same - but in a different scale. A possible list: Plain error in the names (variables, functions). Inability to see the obvious in your code. Misreading. Lack of concentration. Trying to use a technology you have not mastered. Errors with data types. Time required to understand your previous code or your documentation. Trying to do something more than requested because you enjoy it Using solutions more complicated than required because you enjoy it. Plain logical errors. Errors due to your fault in communications. Distraction My first personal issue: "Trying to use a technology you do not master." I have to use daily several technologies and I often need to spend significant time correcting code because my assumptions were plainly wrong. Reasons for this: production needs put high pressure and make difficult to find the time to learn. I try to address this reading technical books - as many as I can - even if this actually consumes a lot of time.

• SQL SERVER – BI Quiz Hint – Performance Tuning Cubes – Hints

  - by pinaldave

  I earlier wrote about SQL BI Quiz over here and here. The details of the quiz is here: Working with huge data is very common when it is about Data Warehousing. It is necessary to create Cubes on the data to make it meaningful and consumable. There are cases when retrieving the data from cube takes lots of the time. Let us assume that your cube is returning you data very quickly. Suddenly on one day it is returning the data very slowly. What are the three things will you to diagnose this. After diagnose what you will do to resolve performance issue. Participate in my question over here I required BI Expert Jason Thomas to help with few hints to blog readers. He is one of the leading SSAS expert and writes a complicated subject in simple words. If queries were executing properly before but now take a long time to return the data, it means that there has been a change in the environment in which it is running. Some possible changes are listed below:-  1) Data factors:- Compare the data size then and now. Increase in data can result in different execution times. Poorly written queries as well as poor design will not start showing issues till the data grows. How to find it out? (Ans : SQL Server profiler and Perfmon Counters can be used for identifying the issues and performance  tuning the MDX queries)  2) Internal Factors:- Is some slow MDX query / multiple mdx queries running at the same time, which was not running when you had tested it before? Is there any locking happening due to proactive caching or processing operations? Are the measure group caches being cleared by processing operations? (Ans : Again, profiler and perfmon counters will help in finding it out. Load testing can be done using AS Performance Workbench (http://asperfwb.codeplex.com/) by running multiple queries at once)  3) External factors:- Is some other application competing for the same resources?  HINT : Read “Identifying and Resolving MDX Query Performance Bottlenecks in SQL Server 2005 Analysis Services” (http://sqlcat.com/whitepapers/archive/2007/12/16/identifying-and-resolving-mdx-query-performance-bottlenecks-in-sql-server-2005-analysis-services.aspx) Well, these are great tips. Now win big prizes by participate in my question over here.

• Impulsioned jumping

  - by Mutoh

  There's one thing that has been puzzling me, and that is how to implement a 'faux-impulsed' jump in a platformer. If you don't know what I'm talking about, then think of the jumps of Mario, Kirby, and Quote from Cave Story. What do they have in common? Well, the height of your jump is determined by how long you keep the jump button pressed. Knowing that these character's 'impulses' are built not before their jump, as in actual physics, but rather while in mid-air - that is, you can very well lift your finger midway of the max height and it will stop, even if with desacceleration between it and the full stop; which is why you can simply tap for a hop and hold it for a long jump -, I am mesmerized by how they keep their trajetories as arcs. My current implementation works as following: While the jump button is pressed, gravity is turned off and the avatar's Y coordenate is decremented by the constant value of the gravity. For example, if things fall at Z units per tick, it will rise Z units per tick. Once the button is released or the limit is reached, the avatar desaccelerates in an amount that would make it cover X units until its speed reaches 0; once it does, it accelerates up until its speed matches gravity - sticking to the example, I could say it accelerates from 0 to Z units/tick while still covering X units. This implementation, however, makes jumps too diagonal, and unless the avatar's speed is faster than the gravity, which would make it way too fast in my current project (it moves at about 4 pixels per tick and gravity is 10 pixels per tick, at a framerate of 40FPS), it also makes it more vertical than horizontal. Those familiar with platformers would notice that the character's arc'd jump almost always allows them to jump further even if they aren't as fast as the game's gravity, and when it doesn't, if not played right, would prove itself to be very counter-intuitive. I know this because I could attest that my implementation is very annoying. Has anyone ever attempted at similar mechanics, and maybe even succeeded? I'd like to know what's behind this kind of platformer jumping. If you haven't ever had any experience with this beforehand and want to give it a go, then please, don't try to correct or enhance my explained implementation, unless I was on the right way - try to make up your solution from scratch. I don't care if you use gravity, physics or whatnot, as long as it shows how these pseudo-impulses work, it does the job. Also, I'd like its presentation to avoid a language-specific coding; like, sharing us a C++ example, or Delphi... As much as I'm using the XNA framework for my project and wouldn't mind C# stuff, I don't have much patience to read other's code, and I'm certain game developers of other languages would be interested in what we achieve here, so don't mind sticking to pseudo-code. Thank you beforehand.

• Understanding Data Science: Recent Studies

  - by Joe Lamantia

  If you need such a deeper understanding of data science than Drew Conway's popular venn diagram model, or Josh Wills' tongue in cheek characterization, "Data Scientist (n.): Person who is better at statistics than any software engineer and better at software engineering than any statistician." two relatively recent studies are worth reading.   'Analyzing the Analyzers,' an O'Reilly e-book by Harlan Harris, Sean Patrick Murphy, and Marck Vaisman, suggests four distinct types of data scientists -- effectively personas, in a design sense -- based on analysis of self-identified skills among practitioners.  The scenario format dramatizes the different personas, making what could be a dry statistical readout of survey data more engaging.  The survey-only nature of the data,  the restriction of scope to just skills, and the suggested models of skill-profiles makes this feel like the sort of exercise that data scientists undertake as an every day task; collecting data, analyzing it using a mix of statistical techniques, and sharing the model that emerges from the data mining exercise.  That's not an indictment, simply an observation about the consistent feel of the effort as a product of data scientists, about data science.  And the paper 'Enterprise Data Analysis and Visualization: An Interview Study' by researchers Sean Kandel, Andreas Paepcke, Joseph Hellerstein, and Jeffery Heer considers data science within the larger context of industrial data analysis, examining analytical workflows, skills, and the challenges common to enterprise analysis efforts, and identifying three archetypes of data scientist.  As an interview-based study, the data the researchers collected is richer, and there's correspondingly greater depth in the synthesis.  The scope of the study included a broader set of roles than data scientist (enterprise analysts) and involved questions of workflow and organizational context for analytical efforts in general.  I'd suggest this is useful as a primer on analytical work and workers in enterprise settings for those who need a baseline understanding; it also offers some genuinely interesting nuggets for those already familiar with discovery work. We've undertaken a considerable amount of research into discovery, analytical work/ers, and data science over the past three years -- part of our programmatic approach to laying a foundation for product strategy and highlighting innovation opportunities -- and both studies complement and confirm much of the direct research into data science that we conducted. There were a few important differences in our findings, which I'll share and discuss in upcoming posts.

• How to recover from finite-state-machine breakdown?

  - by Earl Grey

  My question may seems very scientific but I think it's a common problem and seasoned developers and programmers hopefully will have some advice to avoid the problem I mention in title. Btw., what I describe bellow is a real problem I am trying to proactively solve in my iOS project, I want to avoid it at all cost. By finite state machine I mean this I have a UI with a few buttons, several session states relevant to that UI and what this UI represents, I have some data which values are partly displayed in the UI, I receive and handle some external triggers (represented by callbacks from sensors). I made state diagrams to better map the relevant scenarios that are desirable and alowable in that UI and application. As I slowly implement the code, the app starts to behave more and more like it should. However, I am not very confident that it is robust enough. My doubts come from watching my own thinking and implementation process as it goes. I was confident that I had everything covered, but it was enough to make a few brute tests in the UI and I quickly realized that there are still gaps in the behavior ..I patched them. However, as each component depends and behaves based on input from some other component, a certain input from user or some external source trigers a chain of events, state changes..etc. I have several components and each behave like this Trigger received on input - trigger and its sender analyzed - output something (a message, a state change) based on analysis The problem is, this is not completely selfcontained, and my components (a database item, a session state, some button's state)...COULD be changed, influenced, deleted, or otherwise modified, outside the scope of the event-chain or desirable scenario. (phone crashes, battery is empty phone turn of suddenly) This will introduce a nonvalid situation into the system, from which the system potentially COULD NOT BE ABLE to recover. I see this (althought people do not realize this is the problem) in many of my competitors apps that are on apple store, customers write things like this "I added three documents, and after going there and there, i cannot open them, even if a see them." or "I recorded videos everyday, but after recording a too log video, I cannot turn of captions on them.., and the button for captions doesn't work".. These are just shortened examples, customers often describe it in more detail..from the descriptions and behavior described in them, I assume that the particular app has a FSM breakdown. So the ultimate question is how can I avoid this, and how to protect the system from blocking itself? EDIT I am talking in the context of one viewcontroller's view on the phone, I mean one part of the application. I Understand the MVC pattern, I have separate modules for distinct functionality..everything I describe is relevant to one canvas on the UI.

• Aptronyms: fitting the profession to the name

  - by Tony Davis

  Writing a recent piece on the pains of index fragmentation, I found myself wondering why, in SQL Server, you can’t set the equivalent of a fill factor, on a heap table. I scratched my head…who might know? Phil Factor, of course! I approached him with a due sense of optimism only to find that not only did he not know, he also didn’t seem to care much either. I skulked off thinking how this may be the final nail in the coffin of nominative determinism. I’ve always wondered if there was anything in it, though. If your surname is Plumb or Leeks, is there even a tiny, extra percentage chance that you’ll end up fitting bathrooms? Some examples are quite common. I’m sure we’ve all met teachers called English or French, or lawyers called Judge or Laws. I’ve also known a Doctor called Coffin, a Urologist called Waterfall, and a Dentist called Dentith. Two personal favorites are Wolfgang Wolf who ended up managing the German Soccer team, Wolfsburg, and Edmund Akenhead, a Crossword Editor for The Times newspaper. Having forgiven Phil his earlier offhandedness, I asked him for if he knew of any notable examples. He had met the famous Dr. Batty and Dr. Nutter, both Psychiatrists, knew undertakers called Death and Stiff, had read a book by Frederick Page-Turner, and suppressed a giggle at the idea of a feminist called Gurley-Brown. He even managed to better my Urologist example, citing the article on incontinence in the British Journal of Urology (vol.49, pp.173-176, 1977) by A. J. Splatt and D. Weedon. What, however, if you were keen to gently nudge your child down the path to a career in IT? What name would you choose? Subtlety probably doesn’t really work, although in a recent interview, Rodney Landrum did congratulate PowerShell MVP Max Trinidad on being named after a SQL function. Grant “The Memory” Fritchey (OK, I made up that nickname) doesn’t do badly either. Some surnames, seem to offer a natural head start, although I know of no members of the Page-Reid clan in the profession. There are certainly families with the Table surname, although sadly, Little Bobby Tables was merely a legend by xkcd. A member of the well-known Key family would need to name their son Primary, or maybe live abroad, to make their mark. Nominate your examples of people seemingly destined, by name, for their chosen profession (extra points for IT). The best three will receive a prize. Cheers, Tony.

• Most Unprofessional Workplace

  - by TehGrumpyCoder

  I've worked lots of places in lots of roles: Delivery truck driver, Boilermaker, antenna rigger, Professional Musician, Electronic Technician, Electrical Engineer, and for most of my career: Software Turkey. I want to say this large company is the most unprofessional place I've ever worked, but then I think about other jobs such as TTI that stiffed us all for 10 months salary -- or had us work 2-1/2 years at 66% however you want to look at it, or maybe NeoPlanet with a cast from a bad sitcom running the show, I could go on, but I digress (as usual). So maybe this place isn't the *most* unprofessional, but the personnel rank up there. I'm in a small room off a factory. There are 3 managerial offices, and 36 common-folk of various skill-sets in a variety of single to quad cubicles. No matter where you sit though, because of the layout and location, you've got a hard wall as one wall of your cubicle. Because of that hard wall, everything echoes. I get off the phone, and the guy in the next cubicle makes a comment in response to my phone conversation... I hate that it can be heard and I hate that they do that! These people have no problem yelling from cube to cube to carry on running conversations some of which are actually work-related. There's a lady two cubes away that talks so loud I can clearly hear every phone conversation she has... all work-related but still... Then the one in the next cubicle must have been raised on a farm because there's only one volume setting: LOUD... "HEY MARGE, CAN I GET IN FOR A QUICK APPOINTMENT AFTER WORK TONIGHT?" ... sigh Also that cube is the 'party cube' so that's where all the candy, cake, donuts, and leftovers sits. Anything MzLoud brings in has to have a verbal recipe associated with it at least 10 times during the day, and of course at volume. I've had running conversations over the top of my cube from people in the next one on each side. The weird thing is... the boss sits with an open door closer to this whole fiasco than me. So I wear a pair of Bose noise-cancelling headphones, and crank up Kenny Burrell, Herb Ellis, Wes Montgomery, or Jimmy Smith to the point I can't hear the racket... what the heck, I already have a hearing loss from playing guitar.

• Where would my different development rhythm be suitable for the work?

  - by DarenW

  Over the years I have worked on many projects, with some successful and a great benefit to the company, and some total failures with me getting fired or otherwise leaving. What is the difference? Naturally I prefer the former and wish to avoid the latter, so I'm pondering this issue. The key seems to be that my personal approach differs from the norm. I write code first, letting it be all spaghetti and chaos, using whatever tools "fit my hand" that I'm fluent in. I try to organize it, then give up and start over with a better design. I go through cycles, from thinking-design to coding-testing. This may seem to be the same as any other development process, Agile or whatever, cycling between design and coding, but there does seem to be a subtle difference: The methods (ideally) followed by most teams goes design, code; design, code; ... while I'm going code, design; code, design; (if that makes any sense.) Music analogy: some types of music have a strong downbeat while others have prominent syncopation. In practice, I just can't think in terms of UML, specifications and so on, but grok things only by attempting to code and debug and refactor ad-hoc. I need the grounding provided by coding in order to think constructively, then to offer any opinions, advice or solutions to the team and get real work done. In positions where I can initially hack up cowboy code without constraints of tool or language choices, I easily gain a "feel" for the data, requirements etc and eventually do good work. In formalized positions where paperwork and pure "design" comes first and only later any coding (even for small proof-of-concept projects), I am lost at sea and drown. Therefore, I'd like to know how to either 1) change my rhythm to match the more formalized methodology-oriented team ways of doing things, or 2) find positions at organizations where my sense of development rhythm is perfect for the work. It's probably unrealistic for a person to change their fundamental approach to things. So option 2) is preferred. So where I can I find such positions? How common is my approach and where is it seen as viable but different, and not dismissed as undisciplined or cowboy coder ways?

• Please help me give this principle a name

  - by Brent Arias

  As a designer, I like providing interfaces that cater to a power/simplicity balance. For example, I think the LINQ designers followed that principle because they offered both dot-notation and query-notation. The first is more powerful, but the second is easier to read and follow. If you disagree with my assessment of LINQ, please try to see my point anyway; LINQ was just an example, my post is not about LINQ. I call this principle "dial-able power". But I'd like to know what other people call it. Certainly some will say "KISS" is the common term. But I see KISS as a superset, or a "consumerism" practice. Using LINQ as my example again, in my view, a team of programmers who always try to use query notation over dot-notation are practicing KISS. Thus the LINQ designers practiced "dial-able power", whereas the LINQ consumers practice KISS. The two make beautiful music together. I'll give another example. Imagine a C# logging tool that has two signatures allowing two uses: void Write(string message); void Write(Func<string> messageCallback); The purpose of the two signatures is to fulfill these needs: //Every-day "simple" usage, nothing special. myLogger.Write("Something Happened" + error.ToString() ); //This is performance critical, do not call ToString() if logging is //disabled. myLogger.Write( () => { "Something Happened" + error.ToString() }); Having these overloads represents "dial-able power," because the consumer has the choice of a simple interface or a powerful interface. A KISS-loving consumer will use the simpler signature most of the time, and will allow the "busy" looking signature when the power is needed. This also helps self-documentation, because usage of the powerful signature tells the reader that the code is performance critical. If the logger had only the powerful signature, then there would be no "dial-able power." So this comes full-circle. I'm happy to keep my own "dial-able power" coinage if none yet exists, but I can't help think I'm missing an obvious designation for this practice. p.s. Another example that is related, but is not the same as "dial-able power", is Scott Meyer's principle "make interfaces easy to use correctly, and hard to use incorrectly."

• Great Expectations - Fusion HCM Highlights at OOW

  - by Kathryn Perry

  A guest post by Lisa Conley, Principal Product Strategy Manager, Fusion HCM, Oracle Applications Development Oracle Open World is just around the corner! There's always so much to see and do and learn at the conference so I want to share some of the 'don't miss' Fusion HCM highlights with you. (Use this tool to search by session number to get a full description.) For starters, we have several customers who will be sharing their Fusion HCM implementation stories. We'll kick off these presentations with a customer panel at 12:15 on Monday in Moscone West 2005 (CON9420). You'll hear from Zillow, the Gerson Lehrman Group, UBS, and ConAgra about their experiences with our products. Oracle partners MarketSphere (CON8581) and eVerge (CON3800) have implemented Fusion HCM themselves and and will talk about how they'll use their experiences to help customers with their implementations (both are in Moscone West 2006). Beth Correa, CEO of Official Payroll Advisor, will highlight her favorite things about Oracle Fusion HCM Payroll on Tuesday at 11:45 in Moscone West 2006 (CON6691). And you'll get to hear from customers again when they speak with Steve Miranda in his Oracle Applications: Strategic Directions and Recommendations session on Tuesday at 1:15 in Moscone West 2002/2004 (CON11434). To bring it all together for you, we've listed all your Fusion HCM opportunities to learn and interact in this Focus On Document. I am really looking forward to the sessions on Human Capital Management in the Cloud. The Oracle Cloud combines the multiple product offerings into a single environment that leverages a common technology infrastructure enabling users to focus on their business - not the business of managing environments. On Tuesday at 10:15 in Moscone West 2002/2004, there is a General Session entitled the Future of Oracle HCM -- Strategy and Roadmap (GEN9505). This will touch on all product lines. Fusion HCM will be highlighted in Gretchen Alarcon's Oracle HCM: Overview, Strategy, Customer Experiences, and Roadmap session on Monday at 12:15 in Moscone West 2005 (CON9410). Also on Tuesday at 1:15 in Moscone West 2006, is a session focused on Talent Management and how you can try out these new products, co-existing with your current product set (CON9430). This is important in that you can test the waters before diving in. ConAgra will be sharing their experience in this session as well.  And of course, if you want to have a personal demonstration, please come by the Oracle DEMOgrounds in West Exhibition Hall Level 1 or the Oracle Cloud Services Lounge at Moscone West Level 3 where our Oracle HCM Cloud Services experts will be ready to answer your questions. I hope you have a wonderful week in San Francisco.Lisa ConleyPrincipal Product Strategy Manager, Fusion HCMApplications DevelopmentOracle Corporation

• Developing add-ins for multiple versions of Office

  - by Pranav

  Do you want to develop an add-in targeting multiple versions of Office? And you have basic questions like “Is it possible to do? ” and “How to do it?” ? Then you came to the right place. Few months back, I got a requirement to developed add-ins for Outlook 2003 and Outlook 2007. The functionality for both the versions is same. A doubt stroked… when the functionality is same, why would I develop two add-ins separately? Why don’t I make a single build for both the versions of Office? Then I started searching for techniques to develop add-ins which works in both (2003 and 2007) and read many articles written by VSTO Experts in their blogs, Official VSTO Blog, MSDN, Forums and what not. Misha Says: Theoretically, you can develop an add-in for multiple versions of Microsoft Office by catering to the lowest common denominator. This means if you use an Excel 2003 add-in template in Visual Studio 2008, you would be able to develop and debug this with Excel 2007. However if you try this, you may meet these error messages: “You cannot debug or run this project, because the required version of the Microsoft Office application is not installed.”, followed by “Unable to start debugging.” You can develop Office 2003 add-in in a system where Office 2007 is installed. The following is the procedure that demonstrates how to update your Visual Studio debugging options to use Microsoft Outlook 2007 to debug an add-in targeting Microsoft Outlook 2003. On the Project menu, click on ProjectName Properties Click on the Debug tab In the Start Action pane, click the Start external program radio button Click the file browser button and navigate to %ProgramFiles%\Microsoft Office\Office12 Choose Outlook.exe and click Open Press F5 to debug your add-in For more details. Go through this article in Misha Shneerson’s Blog. There are some tips and tricks to be followed and the things that one needs to take care while developing add-ins targeting multiple versions of Office in Andrew’s Blog. Have a look at this too. You might find it interesting and useful. http://blogs.msdn.com/andreww/archive/2007/06/15/can-you-build-one-add-in-for-multiple-versions-of-office.aspx Here is an MSDN article on Running Solutions in Different Versions of Microsoft Office http://msdn.microsoft.com/en-us/library/bb772080.aspx Hope this helps!

• BPM ADF Task forms. Checking whether the current user is in a BPM Swimlane

  - by Christopher Karl Chan

  @page { margin: 0.79in } P { margin-bottom: 0.08in } --Focus So this blog entry will focus on BPM Swimlane roles and users from a ADF context. So we have an ADF Task Details Form and we are in the process of making it richer and dynamic in functionality. A common requirement could be to dynamically show different areas based on the user logged into the workspace. Perhaps even we want to know even what swim-lane role the user belongs to. It is is a little bit harder to achieve then one thinks unless you know the trick. The Challenge The tricky part here is that the ADF Task Details Form is in fact part of a separate J2EE application to the main workspace. So if you try to use Java or Expression Language to get the logged in user you will only find anonymous and none of the BPM Roles you will be expecting. So what to do? The Magic First add the BC4J Security library to your view project. Then Restart JDeveloper. Now find the web.xml file in the view project of your ADF Task Details Application and look for the JpsFilter section. Then add in the following section. <init-param> <param-name>application.name</param-name> <param-value>OracleBPMProcessRolesApp</param-value></init-param> This will link your application to that of the BPM workspace. Then in your dynamic part of your ADF form you can now check whether the user logged into the BPM Workspace belongs in a BPM swim-lane in any BPM process. The best way to do this is by using expression language in the JSF page itself. Here I am simply changing the rendered flag to either true or false and thereby hiding or showing a section. Perhaps you are re-using the same form for a task in an approver swim-lane and ordinary user swimlane. So we only want the approver to see this field. So call the built in function to check if the user is a member of the BPM swim-lane role. The name of the role must be of the syntax BPMProject.RoleName <af:outputText value="This will only be rendered when the user is part of the BPM Swimlane Role rendered="#{securityContext.userInRole['BPMProjectName.Rolename']}"/> Now you must redeploy your ADF Task Form project Now (in the image above) the text will ONLY get rendered in the Task Details Form only if the user logged into the workspace is a member of the swimlane Unsecure of the BPM project SimpleTask

• Configurable Objects - Introduction

  - by Anthony Shorten

  One of the interesting facilities in the framework is Configurable Object functionality (it is also known as Task Optimization and also known as Cool Tools). The idea is that any implementation can create their own views of the base product objects and services and implement functionality against those new views. For example, in Oracle Utilities Customer Care and Billing, there is a Person object. That object is used to store and manage information about individuals as well as companies. In the base product you would use the Person Maintenance screen and fill in some of the screen when you wanted to register or maintain and individual as well and fill out other parts of the screen when you wanted to register or maintain a company. This can be somewhat confusing to some customers. Using Configurable Objects this can be simplified. A business object can be created that is a view of the any object. For example, you could create a Human business object which would cover the aspects of the Person object pertaining to an individual and a Company business object to cover the aspects unique to a company. Even the tag names (i.e. Field Names) in the object can be changed to be more what the implementation is familiar with. The object can also restructure the object. For example, a common identifier for an individual in the USA is the Social Security number, this value is a Person Identifier (as this varies in each country). In the new Human object you can remap the Person Identifier as a Social Security number. To define a Business Object you use a schema editor built into the browser user interface and use a mapping language to setup the business objects. An example of the language is shown below in an extract of the schema for the Human business object. As you can see there are mapping as well as formatting and other tags. This information can be built manually or using a wizard which generates the base structure for you to alter. This is all stored as meta data when saved. Once a Business object is built it can be used as basis for code, other business objects (we support inheritance), called by a screen (called a UI Map) or even as a Web Service. This is just a start with Configurable Objects as you can also create views of base services called Business Services, Service Scripts used for non-object or complex object processing (as well as other things), UI Maps used for screens and Data Areas to reuse definitions across multiple objects. Configurable Objects are powerful and I only really touched on them here. Over the next few months I hope to add lots more entries about them.

• Adding Column to a SQL Server Table

  - by Dinesh Asanka

  Adding a column to a table is  common task for  DBAs. You can add a column to a table which is a nullable column or which has default values. But are these two operations are similar internally and which method is optimal? Let us start this with an example. I created a database and a table using following script: USE master Go --Drop Database if exists IF EXISTS (SELECT 1 FROM SYS.databases WHERE name = 'AddColumn') DROP DATABASE AddColumn --Create the database CREATE DATABASE AddColumn GO USE AddColumn GO --Drop the table if exists IF EXISTS ( SELECT 1 FROM sys.tables WHERE Name = 'ExistingTable') DROP TABLE ExistingTable GO --Create the table CREATE TABLE ExistingTable (ID BIGINT IDENTITY(1,1) PRIMARY KEY CLUSTERED, DateTime1 DATETIME DEFAULT GETDATE(), DateTime2 DATETIME DEFAULT GETDATE(), DateTime3 DATETIME DEFAULT GETDATE(), DateTime4 DATETIME DEFAULT GETDATE(), Gendar CHAR(1) DEFAULT 'M', STATUS1 CHAR(1) DEFAULT 'Y' ) GO -- Insert 100,000 records with defaults records INSERT INTO ExistingTable DEFAULT VALUES GO 100000 Before adding a Column Before adding a column let us look at some of the details of the database. DBCC IND (AddColumn,ExistingTable,1) By running the above query, you will see 637 pages for the created table. Adding a Column You can add a column to the table with following statement. ALTER TABLE ExistingTable Add NewColumn INT NULL Above will add a column with a null value for the existing records. Alternatively you could add a column with default values. ALTER TABLE ExistingTable Add NewColumn INT NOT NULL DEFAULT 1 The above statement will add a column with a 1 value to the existing records. In the below table I measured the performance difference between above two statements. Parameter Nullable Column Default Value CPU 31 702 Duration 129 ms 6653 ms Reads 38 116,397 Writes 6 1329 Row Count 0 100000 If you look at the RowCount parameter, you can clearly see the difference. Though column is added in the first case, none of the rows are affected while in the second case all the rows are updated. That is the reason, why it has taken more duration and CPU to add column with Default value. We can verify this by several methods. Number of Pages The number of data pages can be obtained by using DBCC IND command. Though, this an undocumented dbcc command, many experts are ok to use this command in production. However, since there is no official word from Microsoft, use this “at your own risk”. DBCC IND (AddColumn,ExistingTable,1) Before Adding the Columns 637 Adding a Column with NULL 637 Adding a column with DEFAULT value 1270 This clearly shows that pages are physically modified. Please note, a high value indicated in the Adding a column with DEFAULT value  column is also a result of page splits. Continues…

• Networking Guidelines

  - by ACShorten

  One of the things I have noticed in my years in IT is the changes in networking. In the past networking was pretty simple with the host name and name resolution (via DNS) being pretty simple. Some sites still use this simple networking setup. These days, more complex name resolution, proxies, firewalls, demarcation nd virtualization, can make networking more complex. This can cause issues when installing products with in built networking that can frustrate even seasoned veterans. I have put together a few basic guidelines to hopefully help along with product installation and getting a product to operate in a somewhat complex network setup. All the components of the product (including the infrastructure) need to communicate via a network (even it is within a local machine/host). Ensure any host names referred to within configuration files are accessible via your networking setup. This may mean defining the hosts to the machines, to the DNS for name resolution and even your firewall to allow machines to communicate within your network. Make sure the ports used for any of the infrastructure are accessible (even through your firewall) and are unique within the host. Host duplication can cause the product to fail on startup as the port is already in use. If there are still issues, consider using localhost as your host name. I have used this in so many situations that I tend to use it now as a default anytime I install anything myself. Most Oracle products suggest to use localhost when using dynamic host or dynamic IP addresses and this is no different for the Oracle Utilities Application Framework. If you do use localhost then installing a Loopback Adapter for the operating system is recommended to force networking to a minimum. Usually localhost resolves to 127.0.0.1. When using multiple network connections, especially in a virtualized environment, ensure the host and ports used are relevent for the network cards you have setup. One of the common issues is finding the product is using a vierualized network card only to find that it is not setup for correct networking. If you are using the batch component, do not forget to ensure that the multicast protocol is enabled on your host and that the multicast address and port number specified are valid and accessible from all machines in the batch cluster (if clustering used). The same advice applies if you are using unicast where each host/port combination should be accessible. Hopefully these basic networking recommendations will help minimize any networking issues you might encounter.

• SQL SERVER – Get 2 of My Books FREE at Koenig Tech Day – Where Technologies Converge!

  - by pinaldave

  As a regular reader of my blog – you must be aware of that I love to write books and talk about various subjects of my book. The founders of Koenig Solutions are my very old friends, I know them for many years. They have been my biggest supporter of my books. Coming weekend they have a technology event at their Bangalore Location. Every attendee of the technology event will get a set of two books worth Rs. 450 – ‘SQL Server Interview Questions And Answers‘ and ‘SQL Wait Stats Joes 2 Pros‘. I am going to cover a couple of topics of the books and present  as well. I am very confident that every attendee will be having a great time. I will be covering following subjects: SQL Server Tricks and Tips for Blazing Fast Performance Slow Running Queries (SQL) are the most common problem that developers face while working with SQL Server. While it is easy to blame the SQL Server for unsatisfactory performance, however the issue often persists with the way queries have been written, and how SQL Server has been set up. The session will focus on the ways of identifying problems that slow down SQL Servers, and tricks to fix them. Developers will walk out with scripts and knowledge that can be applied to their servers, immediately post the session. After the session is over – I will point to what exact location in the book where you can continue for the further learning. I am pretty excited, this is more like book reading but in entire different format. The one day event will cover four technologies in four separate interactive sessions on: Microsoft SQL Server Security VMware/Virtualization ASP.NET MVC Date of the event: Dec 15, 2012 9 AM to 6PM. Location of the event:  Koenig Solutions Ltd. # 47, 4th Block, 100 feet Road, 3rd Floor, Opp to Shanthi Sagar, Koramangala, Bangalore- 560034 Mobile : 09008096122 Office : 080- 41127140 Organizers have informed me that there are very limited seats for this event and technical session based on my book will start at Sharp 9 AM. If you show up late there are chances that you will not get any seats. Registration for the event is a MUST. Please visit this link for further information.

• What are the tradeoffs for using 'partial view models'?

  - by Kenny Evitt

  I've become aware of an itch due to some non-DRY code pertaining to view model classes in an (ASP.NET) MVC web application and I'm thinking of scratching my itch by organizing code in various 'partial view model' classes. By partial-view-model, I'm referring to a class like a view model class in an analogous way to how partial views are like views, i.e. a way to encapsulate common info and behavior. To strengthen the 'analogy', and to aid in visually organizing the code in my IDE, I was thinking of naming the partial-view-model classes with a _ prefix, e.g. _ParentItemViewModel. As a slightly more concrete example of why I'm thinking along these lines, imagine that I have a domain-model-entity class ParentItem and the user-friendly descriptive text that identifies these items to users is complex enough that I'd like to encapsulate that code in a method in a _ParentItemViewModel class, for which I can then include an object or a collection of objects of that class in all the view model classes for all the views that need to include a reference to a parent item, e.g. ChildItemViewModel can have a ParentItem property of the _ParentItemViewModel class type, so that in my ChildItemView view, I can use @Model.ParentItem.UserFriendlyDescription as desired, like breadcrumbs, links, etc. Edited 2014-02-06 09:56 -05 As a second example, imagine that I have entity classes SomeKindOfBatch, SomeKindOfBatchDetail, and SomeKindOfBatchDetailEvent, and a view model class and at least one view for each of those entities. Also, the example application covers a lot more than just some-kind-of-batches, so that it wouldn't really be useful or sensible to include info about a specific some-kind-of-batch in all of the project view model classes. But, like the above example, I have some code, say for generating a string for identifying a some-kind-of-batch in a user-friendly way, and I'd like to be able to use that in several views, say as breadcrumb text or text for a link. As a third example, I'll describe another pattern I'm currently using. I have a Contact entity class, but it's a fat class, with dozens of properties, and at least a dozen references to other fat classes. However, a lot of view model classes need properties for referencing a specific contact and most of those need other properties for collections of contacts, e.g. possible contacts to be referenced for some kind of relationship. Most of these view model classes only need a small fraction of all of the available contact info, basically just an ID and some kind of user-friendly description (i.e. a friendly name). It seems to be pretty useful to have a 'partial view model' class for contacts that all of these other view model classes can use. Maybe I'm just misunderstanding 'view model class' – I understand a view model class as always corresponding to a view. But maybe I'm assuming too much.

• Developer – Cross-Platform: Fact or Fiction?

  - by Pinal Dave

  This is a guest blog post by Jeff McVeigh. Jeff McVeigh is the general manager of Performance Client and Visual Computing within Intel’s Developer Products Division. His team is responsible for the development and delivery of leading software products for performance-centric application developers spanning Android*, Windows*, and OS* X operating systems. During his 17-year career at Intel, Jeff has held various technical and management positions in the fields of media, graphics, and validation. He also served as the technical assistant to Intel’s CTO. He holds 20 patents and a Ph.D. in electrical and computer engineering from Carnegie Mellon University. It’s not a homogenous world. We all know it. I have a Windows* desktop, a MacBook Air*, an Android phone, and my kids are 100% Apple. We used to have 2.5 kids, now we have 2.5 devices. And we all agree that diversity is great, unless you’re a developer trying to prioritize the limited hours in the day. Then it’s a series of trade-offs. Do we become brand loyalists for Google or Apple or Microsoft? Do we specialize on phones and tablets or still consider the 300M+ PC shipments a year when we make our decisions on where to spend our time and resources? We weigh the platform options, monetization opportunities, APIs, and distribution models. Too often, I see developers choose one platform, or write to the lowest common denominator, which limits their reach and market success. But who wants to be ?me too”? Cross-platform coding is possible in some environments, for some applications, for some level of innovation—but it’s not all-inclusive, yet. There are some tricks of the trade to develop cross-platform, including using languages and environments that ?run everywhere.” HTML5 is today’s answer for web-enabled platforms. However, it’s not a panacea, especially if your app requires the ultimate performance or native UI look and feel. There are other cross-platform frameworks that address the presentation layer of your application. But for those apps that have a preponderance of native code (e.g., highly-tuned C/C++ loops), there aren’t tons of solutions today to help with code reuse across these platforms using consistent tools and libraries. As we move forward with interim solutions, they’ll improve and become more robust, based, in no small part, on our input. What’s your answer to the cross-platform challenge? Are you fully invested in HTML5 now? What are your barriers? What’s your vision to navigate the cross-platform landscape?  Here is the link where you can head next and learn more about how to answer the questions I have asked: https://software.intel.com/en-us Republished with permission from here.

• WinMo&rsquo;s Demise: Notifying Next of &ldquo;Kin&rdquo;

  This past Monday, April 12th, Visual Studio 2010 was launched.  And on that same day, Microsoft also launched a new line of  mobile phone handsets, called Kin.  The two product launches are actually connected, but only by what they do not have in common, and what they commonly lack. On the former point: VS 2010 had released to manufacturing a couple weeks prior to its launch.  The Kin phones, meanwhile are not yet available.  We don’t even know what they will cost.  (And I think cost will be a major factor in Kin’s success…I told ChannelWeb’s Yara Souza so in this article). What do the two products both lack? Simple: Windows Mobile 6.x. For example, Kin seems to be based on the same platform as Windows Phone 7 (albeit a subset).  And VS 2010 does not support .NET Compact Framework development, which means no .NET development support for WinMo 6.x and earlier. So I guess April 12th marks Windows Phone “clean slate day.”  If you want to develop for the old phone platform, you will need to use the old version of Visual Studio (i.e. 2008).  Luckily VS 2010 and 2008 can be installed side-by-side.  But I doubt that’s much consolation to developers who still target WinMo 6.5 and earlier. Remember, WinMo isn’t just about the phone.  There are all sorts of non-telephony mobile devices, including ruggedized Pocket PC-style instruments, bar code readers and shop-floor-deployed units that don’t run Windows Phone 7 and couldn’t, even if they wanted to. Where will developers in these markets go?  I would guess some will stick with WinMo 6.x and earlier, until Windows Phone 7 can handle their workloads, assuming that does indeed happen.  Others will likely go to Google’s Android platform. For OEMs and developers who need a customizable mobile software stack, Android is turning out to be out-WinMo-ing WinMo.  As I wrote in this post, Google took Microsoft’s model (minus the licensing fees) and combined it with a modern SmartPhone feature set (rather than a late 90s/early oughts PDA paradigm), to great success.  You might say Google embraced and extended. You might also say Microsoft shunned and withdrew.

• Access-based Enumeration (December 04, 2009)

  - by user12612012

  Access-based Enumeration (ABE) is another recent addition to the Solaris CIFS Service - delivered into snv_124.  Designed to be compatible with Windows ABE, which was introduced in Windows Server 2003 SP1, this feature filters directory content based on the user browsing the directory.  Each user can only see the files and directories to which they have access.  This can be useful to implement an out-of-sight, out-of-mind policy or simply to reduce the number of files presented to each user - to make it easier to find files in directories containing a large number of files. ABE is managed on a per share basis by a new boolean share property called, as you might imagine, abe, which is described insharemgr(1M).  When set to true, ABE filtering is enabled on the share and directory entries to which the user has no access will be omitted from directory listings returned to the client.  When set to false or not defined, ABE filtering will not be performed on the share.  The abe property is not defined by default.Administration is straightforward, for example: # zfs sharesmb=abe=true,name=jane tank/home/jane# sharemgr show -vp    zfs       zfs/tank/home/jane nfs=() smb=()          jane=/export/home/jane     smb=(abe="true") ABE is also supported via sharemgr(1M) and on smbautohome(4) shares. Note that even though a file is visible in a share, with ABE enabled, it doesn't automatically mean that the user will always be able to open the file.  If a user has read attribute access to a file ABE will show the it but access will be denied if this user tries to open the file for reading or writing. We considered supporting ABE on NFS shares, as suggested by the name of PSARC/2009/375, but we ran into problems due to NFS client readdir caching.  NFS clients maintain a common directory entry cache for all users, which not only defeats the intent of ABE but can lead to very confusing results.  If multiple users are looking at the content of a directory with ABE enabled, the entries that get cached will depend on who looks at the directory first.  Subsequent users may see files that ABE on the server would have filtered out or files may be missing because they were filtered out for the original user. Although this issue can be resolved by disabling the NFS client readdir cache, this was deemed to be an unsuitable solution because it would create a dependency between a server share property and the configuration on all NFS clients, and there was the potential for differences in behavior across the various NFS clients.  It just seemed to add unnecessary administration complexity so we pulled it out.
