• World Record Batch Rate on Oracle JD Edwards Consolidated Workload with SPARC T4-2

  - by Brian

  Oracle produced a World Record batch throughput for single system results on Oracle's JD Edwards EnterpriseOne Day-in-the-Life benchmark using Oracle's SPARC T4-2 server running Oracle Solaris Containers and consolidating JD Edwards EnterpriseOne, Oracle WebLogic servers and the Oracle Database 11g Release 2. The workload includes both online and batch workload. The SPARC T4-2 server delivered a result of 8,000 online users while concurrently executing a mix of JD Edwards EnterpriseOne Long and Short batch processes at 95.5 UBEs/min (Universal Batch Engines per minute). In order to obtain this record benchmark result, the JD Edwards EnterpriseOne, Oracle WebLogic and Oracle Database 11g Release 2 servers were executed each in separate Oracle Solaris Containers which enabled optimal system resources distribution and performance together with scalable and manageable virtualization. One SPARC T4-2 server running Oracle Solaris Containers and consolidating JD Edwards EnterpriseOne, Oracle WebLogic servers and the Oracle Database 11g Release 2 utilized only 55% of the available CPU power. The Oracle DB server in a Shared Server configuration allows for optimized CPU resource utilization and significant memory savings on the SPARC T4-2 server without sacrificing performance. This configuration with SPARC T4-2 server has achieved 33% more Users/core, 47% more UBEs/min and 78% more Users/rack unit than the IBM Power 770 server. The SPARC T4-2 server with 2 processors ran the JD Edwards "Day-in-the-Life" benchmark and supported 8,000 concurrent online users while concurrently executing mixed batch workloads at 95.5 UBEs per minute. The IBM Power 770 server with twice as many processors supported only 12,000 concurrent online users while concurrently executing mixed batch workloads at only 65 UBEs per minute. This benchmark demonstrates more than 2x cost savings by consolidating the complete solution in a single SPARC T4-2 server compared to earlier published results of 10,000 users and 67 UBEs per minute on two SPARC T4-2 and SPARC T4-1. The Oracle DB server used mirrored (RAID 1) volumes for the database providing high availability for the data without impacting performance.

Oracle offers 70 JD Edwards EnterpriseOne application modules to support a diverse set of business operations. Oracle's Day in the Life (DIL) kit is a suite of scripts that exercises most common transactions of JD Edwards EnterpriseOne applications, including business processes such as payroll, sales order, purchase order, work order, and manufacturing processes, such as ship confirmation. These are labeled by industry acronyms such as SCM, CRM, HCM, SRM and FMS. The kit's scripts execute transactions typical of a mid-sized manufacturing company. The workload consists of online transactions and the UBE – Universal Business Engine workload of 61 short and 4 long UBEs. LoadRunner runs the DIL workload, collects the user’s transactions response times and reports the key metric of Combined Weighted Average Transaction Response time. The UBE processes workload runs from the JD Enterprise Application server. Oracle's UBE processes come as three flavors: Short UBEs < 1 minute engage in Business Report and Summary Analysis, Mid UBEs > 1 minute create a large report of Account, Balance, and Full Address, Long UBEs > 2 minutes simulate Payroll, Sales Order, night only jobs. The UBE workload generates large numbers of PDF files reports and log files. The UBE Queues are categorized as the QBATCHD, a single threaded queue for large and medium UBEs, and the QPROCESS queue for short UBEs run concurrently. Oracle's UBE process performance metric is Number of Maximum Concurrent UBE processes at transaction rate, UBEs/minute. Key Points and Best Practices Two JD Edwards EnterpriseOne Application Servers, two Oracle WebLogic Servers 11g Release 1 coupled with two Oracle Web Tier HTTP server instances and one Oracle Database 11g Release 2 database on a single SPARC T4-2 server were hosted in separate Oracle Solaris Containers bound to four processor sets to demonstrate consolidation of multiple applications, web servers and the database with best resource utilizations. Interrupt fencing was configured on all Oracle Solaris Containers to channel the interrupts to processors other than the processor sets used for the JD Edwards Application server, Oracle WebLogic servers and the database server. A Oracle WebLogic vertical cluster was configured on each WebServer Container with twelve managed instances each to load balance users' requests and to provide the infrastructure that enables scaling to high number of users with ease of deployment and high availability. The database log writer was run in the real time RT class and bound to a processor set. The database redo logs were configured on the raw disk partitions. The Oracle Solaris Container running the Enterprise Application server completed 61 Short UBEs, 4 Long UBEs concurrently as the mixed size batch workload. The mixed size UBEs ran concurrently from the Enterprise Application server with the 8,000 online users driven by the LoadRunner.

• How to prepare for an interview presentation!

  - by Tim Koekkoek

  During an interview process you might be asked to prepare a presentation as one of the steps in the recruitment process. Below, we want to give you some tips to help you prepare for what might be considered a daunting aspect of a recruitment process. Main purpose of the presentation Always keep in mind the main purpose of what the presentation is meant to convey. Generally speaking, an interview presentation is for the company to check if you have the ability to represent and sell the organization (and yourself), to the internal and external stakeholders in the position you are applying for. A presentation is often also part of the recruitment process to check whether you can structure and explain your experience and thoughts in a convincing manner. If you are unsure about the purpose of the presentation, feel free to ask your recruiter for more information. Preparation As with every task you do, preparation is key, so is the case with an interview presentation. It is important to know who your audience is. You have to adapt your presentation to your audience, ensuring that you are presenting the facts which they would want to hear. Furthermore, make sure you practice your presentation beforehand; this will make you more confident in your presenting skills. Also, estimate the length of your presentation as presentations or pitches during the recruitment process are often capped to a certain time limit. Structure Every presentation should have a beginning, middle and an end. Make sure you give an overview of your presentation and tell the audience what they can expect. Your presentation should have a logical order and a clear message. Always build up to your key message with strong arguments and evidence. When speaking about the topic, make sure you convey your points with conviction. Also be sure you believe the message you bring forward, if you don’t believe it yourself, then the audience definitely won’t! Delivery When you think back on successful presentations you have seen, the presenter was most likely always standing up. So if asked to do a presentation, follow this example and make sure you stand up as well. Standing up when you are doing your presentation shows confidence and control. Another important aspect in the delivery of the presentation is to relax and speak slowly and with enough volume for the audience to hear you. Speaking slowly allows the audience the time to absorb the information you are providing to them. Visual Using PowerPoint, or an equivalent, makes it very easy to have a visually attractive presentation. Make sure however that you take into account that the visual aids you use are there to support you, not for you to read word for word what is on the slides! Questions When starting your presentation, it is a good idea to tell your audience that you will deal with any questions they might have at the end of the presentation. This way it doesn’t interrupt your train of thought and the flow of your presentation. Answering questions at the end may give you additional opportunities to further expand on your facts in the topic. Some people might play the “devil’s advocate” role and confront you with opposing opinions, if this is the case, take your time to reiterate your points and remain professional in your response. A good way to deal with this is to start interacting with other members of the audience and ask for their opinions, so it will become a group discussion. This will also shows strong leadership skills, as you are open to discuss and ask for other opinions.

• Principles of Service-Oriented Architecture by Douwe P. van den Bos

  - by JuergenKress

  Today I hosted a session on the Principles of Service-Oriented Architecture for my colleagues at Capgemini. A very interesting session because everyone had a very clear view on the Oracle SOA Suite and a technical background. What we wanted to do was creating a common view on what a Service-Oriented Architecture is, what the benefits are that can be achieved and what is needed to create a Service-Oriented Architecture. During this very interactive session we moved from a clearly technology view on the matter (Oracle SOA Suite) to an architectural view slicing from business to technology. And this is where SOA really kicks in, because it is a philosophy. Here is the presentation on SlideShare: Principles of Service-Oriented Architecture.

• Prioritizing Product Features

  - by Robert May

  A very common task in Agile Environments is prioritization.  Teams that are functioning well will prioritize new features, old features, the backlog, and any other source of stories for the team, and they’ll do it regularly. Not all teams are good at prioritizing according to the real return on investment that building stories will yield to the company.  This is unfortunate.  Too often, teams end up building features that are less valuable, and everyone seems to know it except perhaps the product owner!  Most features built into software are never even used.  Clearly, not much return for features that go unused. So how does a company avoid building features that add little value to the company?  This is a tough question to answer, but usually, this prioritization starts at the top with the executives of the company.  After all, they’re responsible for the overall vision of the company. Here’s what I recommend: Know your market. Know your customers and users. Know where you’re going and what you want to achieve. Implement the Vision Know Your Market We often see companies that don’t know their market.  Personally, I’m surprised by this.  These companies don’t know who their competitors are, don’t know what features make their product desirable in the market, and in many cases, get by with saying, “I’ve been doing this for XX years.  I know what the market wants!”  In many cases, they equate “marketing” with “advertising” and don’t understand the difference. This is almost never true.  Good companies will spend significant amounts of time and money finding out who they’re competing against and what makes their competitors successful in the marketplace.  Good companies understand that marketing involves more than just advertising.  Often, marketing is mostly research and analysis, not sales.  Until you understand your market, you cannot know what features will give you the best return on your investment dollar. Good companies have a marketing department and can answer the next important step which is to know your customers and your users. Know your Customers and Users First, note that I included both customers and users.  They’re often not the same thing.  Users use the product that you build.  Customers buy the product that you build.  It’s a subtle difference, but too often, I’ve seen companies that focus exclusively on one or the other and are not successful simply because they ignore an important part of the group. If your company is doing appropriate marketing, you know that these are two different aspects of your product and that both deserve attention to have a product that is successful in your target market.  Your marketing department should be spending a lot of time understanding these personas and then conveying that information to the company. I’m always surprised when development teams think that they can build a product that people want to use without understanding the users of that product.  Developers think differently than most people in the world.  They know what the computer is doing.  The computer isn’t magic to them.  So when they assume that they know how to build something, they bring with them quite a bit of baggage.  Never assume that you know your customer unless you’re regularly having interaction with them.  Also, don’t just leave this to Marketing or Product Management.  Take them time to get your developers out with the customers as well.  Developers are very smart people, and often, seeing how someone uses their software inspires them to make a much better product. Very often, because the users and customers aren’t know, teams will spend a significant amount of time building apps that are super flexible and configurable so that any possible combination of feature can be used.  This demonstrates a clear lack of understanding of the customer.  Most configuration questions can quickly be answered by talking to the customer.  In most cases, if your software requires significant setup and configuration before its usable, you probably don’t know your customers and users very well. Until you know your customers, you cannot know what features will be most valuable to your customers and you cannot build those features in a way that your customers can use. Know Where You’re Going and What You Want to Achieve Many companies suffer from not having a plan.  Executives will tell the team to make them a plan.  The team, not knowing their market and customers and users, will come up with a plan that doesn’t reflect reality and doesn’t consider ROI.  Management then wonders why the product is doing poorly in the market place. Instead of leaving this up to the teams, as executives, work with Marketing to understand what broad categories of features will sell the most product in the marketplace.  Then, once you’ve determined that, give this vision to the team and let them run with it.  Revise the vision as needed, but avoid changing streams frequently.  Sure, sometimes you need to, but often, executives will change priorities many times a month, leading to nothing more than confusion.  If the team has a vision, they’ll be able to execute that vision far better than they could otherwise. By knowing what products are most important, you can set budgetary goals and guidelines that will help you achieve the vision that was created. Implement the Vision Creating the vision is often where the general executives stop participating in the plan.  The team is responsible for implementing that vision.  Executives should attend showcases and and should remain aware of the progress that the team is making towards meeting the vision, however. Once a broad vision has been created, the team should break that vision down into minimal market features (MMF).  These MMFs should be sized using story points so that, using the team’s velocity, an estimated cost can be determined for each feature.  The product management team should then try to quantify the relative value of the MMFs based on customer feedback and interviews.  Once the value and cost of creating the feature is understood, a return on investment can be calculated.  The features should then be prioritized with the MMF’s that have the highest value and lowest cost rising to the top of features to implement.  Don’t let politics get in the way! Once the MMF’s have been prioritized, they should go through release planning to schedule them for implementation. Conclusion By having a good grasp on the strategy of the company, your Agile teams can be much more effective.  Each and every story the team is implementing will roll up into features that matter to the company and provide ROI to them.  The steps outlined in this post should be repeated on a regular basis.  I recommend reviewing them at least once per quarter to make sure that the vision hasn’t shifted and that the teams are still working on what matters most to the company.

• QotD: Matt Stephens on OpenJDK in 2012 at the Register

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

  While Java SE churns and gets pushed back, the new initiatives do at least show OpenJDK is reinvigorating the Java space. The project has picked up speed just a little too late for the fifth anniversary of the open-sourcing of Java, but if these promised developments really do come together then that means next year should see a series of “one last things” missing from 2011.Matt Stephens in an article in the Register.

• Building InstallShield based Installers using Team Build 2010

  - by jehan

  Last few weeks, I have been working on Application Packaging stuff using all the widely used tools like InstallShield, WISE, WiX and Visual Studio Installer. So, I thought it would be good to post about how to Build the Installers developed using these tools with Team Build 2010. This post will focus on how to build the InstallShield generated packages using Team Build 2010. For the release of VS2010, Microsoft has partnered with Flexera who are the makers of InstallShield to create InstallShield Limited Edition, especially for the customers of Visual Studio. First Microsoft planned to release WiX (Windows Installer Xml) with VS2010, but later Microsoft dropped  WiX from VS2010 due to reasons which are best known to them and partnered with InstallShield for Limited Edition. It disappointed lot of people because InstallShield Limited Edition provides only few features of InstallShield and it may not feasable to build complex installer packages using this and it also requires License, where as WiX is an open source with no license costs and it has proved efficient in building most complex packages. Only the last three features are available in InstallShield Limited Edition from the total features offered by InstallShield as shown in below list.                                                                                            Feature Limited Edition for Visual Studio 2010 Standalone Build System Maintain a clean build machine by using only the part of InstallShield that compiles the installations. InstallShield Best Practices Validation Suite Avoid common installation issues. Try and Die Functionality RCreate a fully functional trial version of your product. InstallShield Repackager Create Windows Installer setups from any legacy installation. Multilingual Support Present installation text in up to 35 languages. Microsoft App-V™ Support Deploy your applications as App-V virtual packages that run without conflict. Industry-Standard InstallScript Achieve maximum flexibility in your installations. Dialog Editor Modify the layout of existing end-user dialogs, create new custom dialogs, and more. Patch Creation Build updates and patches for your products. Setup Prerequisite Editor Easily control prerequisite restart behavior and source locations. String Editor View Control the localizable text strings displayed at run time with this spreadsheet-like table. Text File Changes View Configure search-and-replace actions for content in text files to be modified at run time. Virtual Machine Detection Block your installations from running on virtual machines. Unicode Support Improve multi-language installation development. Support for 64-Bit COM Extraction Extract COM data from a 64-bit COM server. Windows Installer Installation Chaining Add MSI packages to your main installation and chain them together. XML Support Save time by quickly testing XML configuration changes to installation projects. Billboard Support for Custom Branding Display Adobe Flash billboards and other graphic files during the install process. SaaS Support (IIS 7 and SSL Technologies) Easily deploy Windows-based Web applications. Project Assistant Jumpstart a project by using a simplified set of views. Support for Digital Signatures Save time by digitally signing all your files at build time. Easily Run Custom Actions Schedule a custom action to run at precisely the right moment in your installation. Installation Prerequisites Check for and install prerequisites before your installation is executed. To create a InstallShield project in Visual Studio and Build it using Team Build 2010, first you have to add the InstallShield Project template  to your Solution file. If you want to use InstallShield Limited edition you can add it from FileàNewà project àother Project Types àSetup and Deploymentà InstallShield LE and if you are using other versions of InstallShield, then you have to add it from  from FileàNewà project àInstallShield Projects. Here, I’m using  InstallShield 2011 Premier edition as I already have it Installed. I have created a simple package for TailSpin Application which has a Feature called Web, few components and a IIS Web Site for  TailSpin application.   Before started working on this, I thought I may need to build the package by calling invoke process activity in build process template or have to create a new custom activity. But, it got build without any changes to build process template. But, it was failing with below error message. C:\Program Files (x86)\MSBuild\InstallShield\2011\InstallShield.targets (68): The "InstallShield.Tasks.InstallShield" task could not be loaded from the assembly C:\Program Files (x86)\MSBuild\InstallShield\2010Limited\InstallShield.Tasks.dll. Could not load file or assembly 'file:///C:\Program Files(x86)\MSBuild\InstallShield\2011\InstallShield.Tasks.dll' or one of its dependencies. An attempt was made to load a program with an incorrect format. Confirm that the <UsingTask> declaration is correct, that the assembly and all its dependencies are available, and that the task contains a public class that implements Microsoft.Build.Framework.ITask. This error is due to 64-bit build machine which I’m using. This issue will be replicable if you are queuing a build on a 64-bit build machine. To avoid this you have to ensure that you configured the build definition for your InstallShield project to load the InstallShield.Tasks.dll file (which is a 32-bit file); otherwise, you will encounter this build error informing you that the InstallShield.Tasks.dll file could not be loaded. To select the 32-bit version of MSBuild, click the Process tab of your build definition in Team Explorer. Then, under the Advanced node, find the MSBuild Platform setting, and select x86. Note that if you are using a 32-bit build machine, you can select either Auto or x86 for the MSBuild Platform setting.  Once I did above changes, the build got successful.

• Using Radio Button in GridView with Validation

  - by Vincent Maverick Durano

  A developer is asking how to select one radio button at a time if the radio button is inside the GridView.  As you may know setting the group name attribute of radio button will not work if the radio button is located within a Data Representation control like GridView. This because the radio button inside the gridview bahaves differentely. Since a gridview is rendered as table element , at run time it will assign different "name" to each radio button. Hence you are able to select multiple rows. In this post I'm going to demonstrate how select one radio button at a time in gridview and add a simple validation on it. To get started let's go ahead and fire up visual studio and the create a new web application / website project. Add a WebForm and then add gridview. The mark up would look something like this: <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false" > <Columns> <asp:TemplateField> <ItemTemplate> <asp:RadioButton ID="rb" runat="server" /> </ItemTemplate> </asp:TemplateField> <asp:BoundField DataField="RowNumber" HeaderText="Row Number" /> <asp:BoundField DataField="Col1" HeaderText="First Column" /> <asp:BoundField DataField="Col2" HeaderText="Second Column" /> </Columns> </asp:GridView> Noticed that I've added a templatefield column so that we can add the radio button there. Also I have set up some BoundField columns and set the DataFields as RowNumber, Col1 and Col2. These columns are just dummy columns and i used it for the simplicity of this example. Now where these columns came from? These columns are created by hand at the code behind file of the ASPX. Here's the code below: private DataTable FillData() { DataTable dt = new DataTable(); DataRow dr = null; //Create DataTable columns dt.Columns.Add(new DataColumn("RowNumber", typeof(string))); dt.Columns.Add(new DataColumn("Col1", typeof(string))); dt.Columns.Add(new DataColumn("Col2", typeof(string))); //Create Row for each columns dr = dt.NewRow(); dr["RowNumber"] = 1; dr["Col1"] = "A"; dr["Col2"] = "B"; dt.Rows.Add(dr); dr = dt.NewRow(); dr["RowNumber"] = 2; dr["Col1"] = "AA"; dr["Col2"] = "BB"; dt.Rows.Add(dr); dr = dt.NewRow(); dr["RowNumber"] = 3; dr["Col1"] = "A"; dr["Col2"] = "B"; dt.Rows.Add(dr); dr = dt.NewRow(); dr["RowNumber"] = 4; dr["Col1"] = "A"; dr["Col2"] = "B"; dt.Rows.Add(dr); dr = dt.NewRow(); dr["RowNumber"] = 5; dr["Col1"] = "A"; dr["Col2"] = "B"; dt.Rows.Add(dr); return dt; } And here's the code for binding the GridView with the dummy data above. protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { GridView1.DataSource = FillData(); GridView1.DataBind(); } } Okay we have now a GridView data with a radio button on each row. Now lets go ahead and switch back to ASPX mark up. In this example I'm going to use a JavaScript for validating the radio button to select one radio button at a time. Here's the javascript code below: function CheckOtherIsCheckedByGVID(rb) { var isChecked = rb.checked; var row = rb.parentNode.parentNode; if (isChecked) { row.style.backgroundColor = '#B6C4DE'; row.style.color = 'black'; } var currentRdbID = rb.id; parent = document.getElementById("<%= GridView1.ClientID %>"); var items = parent.getElementsByTagName('input'); for (i = 0; i < items.length; i++) { if (items[i].id != currentRdbID && items[i].type == "radio") { if (items[i].checked) { items[i].checked = false; items[i].parentNode.parentNode.style.backgroundColor = 'white'; items[i].parentNode.parentNode.style.color = '#696969'; } } } } The function above sets the row of the current selected radio button's style to determine that the row is selected and then loops through the radio buttons in the gridview and then de-select the previous selected radio button and set the row style back to its default. You can then call the javascript function above at onlick event of radio button like below: <asp:RadioButton ID="rb" runat="server" onclick="javascript:CheckOtherIsCheckedByGVID(this);" /> Here's the output below: On Load: After Selecting a Radio Button: As you have noticed, on initial load there's no default selected radio in the GridView. Now let's add a simple validation for that. We will basically display an error message if a user clicks a button that triggers a postback without selecting  a radio button in the GridView. Here's the javascript for the validation: function ValidateRadioButton(sender, args) { var gv = document.getElementById("<%= GridView1.ClientID %>"); var items = gv.getElementsByTagName('input'); for (var i = 0; i < items.length ; i++) { if (items[i].type == "radio") { if (items[i].checked) { args.IsValid = true; return; } else { args.IsValid = false; } } } } The function above loops through the rows in gridview and find all the radio buttons within it. It will then check each radio button checked property. If a radio is checked then set IsValid to true else set it to false.  The reason why I'm using IsValid is because I'm using the ASP validator control for validation. Now add the following mark up below under the GridView declaration: <br /> <asp:Label ID="lblMessage" runat="server" /> <br /> <asp:Button ID="btn" runat="server" Text="POST" onclick="btn_Click" ValidationGroup="GroupA" /> <asp:CustomValidator ID="CustomValidator1" runat="server" ErrorMessage="Please select row in the grid." ClientValidationFunction="ValidateRadioButton" ValidationGroup="GroupA" style="display:none"></asp:CustomValidator> <asp:ValidationSummary ID="ValidationSummary1" runat="server" ValidationGroup="GroupA" HeaderText="Error List:" DisplayMode="BulletList" ForeColor="Red" /> And then at Button Click event add this simple code below just to test if  the validation works: protected void btn_Click(object sender, EventArgs e) { lblMessage.Text = "Postback at: " + DateTime.Now.ToString("hh:mm:ss tt"); } Here's the output below that you can see in the browser:   That's it! I hope someone find this post useful! Technorati Tags: ASP.NET,JavaScript,GridView

As Oracle has continued to acquire new companies and technologies, it has become essential that we also create a single, unified language and approach for implementation - across the Oracle ecosystem.With the release of OUM 5.1 in 2009, OUM provided full support for all enterprise application implementation projects including Oracle E-Business Suite R12, Siebel CRM, PeopleSoft Enterprise, and JD Edwards EnterpriseOne projects. In 2010, we released OUM training that supports the use of OUM on these types of projects.That support represented a major milestone in the evolution of OUM and enabled implementers to transition to OUM. Consequently, we announced a staggered retirement schedule for Oracle's legacy methods. On January 31, 2011 we announced the retirement of:Oracle Application Implementation Method (AIM)Oracle AIM for Business Flows (ABF)Siebel Results RoadmapLater this year, we will announce the retirement of Compass - the legacy PeopleSoft method - and Data Warehouse Method Fast Track.OUM is available free of charge to Oracle Gold, Platinum, and Diamond partners through the Oracle Partner Network (OPN) [OUM on OPN]. The OUM Customer Program allows customers to obtain copies of the method for their internal use by contracting with Oracle for an engagement of two weeks or longer meeting some additional minimum criteria.There be more retirement announcements in the coming months. For now it's "Adios AIM." Thanks for the memories...

• Creando controles personalizados para asp.net

  - by jaullo

  Si bien es cierto que asp.net contiene muchos controles que nos facilitan la vida, en muchas ocasiones requerimos funcionalidades adicionales. Una de las opciones es recurrir a la creación de controles personalizados. Este será el Primero de varios post que dedicare a mostrar como crear algunos controles personalizados utilizando elementos sumamente sencillos y faciles de entender. Para ello utilizaremos unicamente los regularexpressionvalidator y unas cuantas expresiones regulares. Para este ejemplo extenderemos la funcionalidad de un textbox para que valide números de tarjetas de crédito. Nuestro textbox deberá verificar que existan 16 números, en grupos de 4, separados por un - Entonces, creamos un nuevo proyecto de tipo control de servidor asp.net Primeramente importamos los espacios de nombres Imports System.ComponentModel Imports System.Web Imports System.Web.UI.WebControls Imports System.Web.UI   Segundo creamos nuestra clase Public Class TextboxCreditCardNumber end class Ahora,  le decimos a nuestra clase que vamos a heredar de textbox Public Class TextboxCreditCardNumber           Inherits TextBox end class Una vez que tenemos esto, nuestra base de programación esta lista, asi que vamos a codificar nuestra nueva funcionalidad Declaramos nuestra variables y una propiedad pública que contendrá el mensaje de error que debe ser devuelto al usuario, esta será publica para que pueda ser personalizada.    Private req As New RegularExpressionValidator     Private mstrmensaje As String = "Número de Tarjeta Invalido"     Public Property MensajeError() As String         Get             Return mstrmensaje         End Get         Set(ByVal value As String)             mstrmensaje = value         End Set     End Property   Ahora definimos el metodo OnInit de nuestro control, en el cual asignaremos las propiedad e inicializaremos nuestras funciones    Protected Overrides Sub OnInit(ByVal e As System.EventArgs)         req.ControlToValidate = MyBase.ID         req.ErrorMessage = mstrmensaje         req.Display = ValidatorDisplay.Dynamic         req.ValidationExpression = "^(\d{4}-){3}\d{4}$|^(\d{4} ){3}\d{4}$|^\d{16}$"         Controls.Add(New LiteralControl("&nbsp;"))         Controls.Add(req)         MyBase.OnInit(e)     End Sub   Y por último, definimos el evento render (que es el encarado de dibujar nuestro control) Protected Overrides Sub Render(ByVal writer As System.Web.UI.HtmlTextWriter)         MyBase.Render(writer)         req.RenderControl(writer)     End Sub   Lo unico que nos queda ahora es compilar nuestra clase y añadir nuestro nuevo control al ToolBox de Controles para que pueda ser utilizado.

• Specifying a file name for the FTP and File based transports in OSB

  - by [email protected]

  A common question I receive is how to incorporate a variable value into a file name when using the FTP, SFTP, or File transports in Oracle Service Bus.  For example, if one of the fields in a message being put down to a file by the File transport is an order number variable, then how can you make the order number become part of the file name?  Another example might be if you want to specify the date in the file name.  The transport configuration wizard in OSB does not have an option to allow for this, other than allowing you to specify a static prefix of suffix variable.

• A Reusable Builder Class for Javascript Testing

  - by Liam McLennan

  Continuing on my series of builders for C# and Ruby here is the solution in Javascript. This is probably the implementation with which I am least happy. There are several parts that did not seem to fit the language. This time around I didn’t bother with a testing framework, I just append some values to the page with jQuery. Here is the test code: var initialiseBuilder = function() { var builder = builderConstructor(); builder.configure({ 'Person': function() { return {name: 'Liam', age: 26}}, 'Property': function() { return {street: '127 Creek St', manager: builder.a('Person') }} }); return builder; }; var print = function(s) { $('body').append(s + '<br/>'); }; var build = initialiseBuilder(); // get an object liam = build.a('Person'); print(liam.name + ' is ' + liam.age); // get a modified object liam = build.a('Person', function(person) { person.age = 999; }); print(liam.name + ' is ' + liam.age); home = build.a('Property'); print(home.street + ' manager: ' + home.manager.name); and the implementation: var builderConstructor = function() { var that = {}; var defaults = {}; that.configure = function(d) { defaults = d; }; that.a = function(type, modifier) { var o = defaults[type](); if (modifier) { modifier(o); } return o; }; return that; }; I still like javascript’s syntax for anonymous methods, defaults[type]() is much clearer than the Ruby equivalent @defaults[klass].call(). You can see the striking similarity between Ruby hashes and javascript objects. I also prefer modifier(o) to the equivalent Ruby, yield o.

• Full-text indexing? You must read this

  - by Kyle Hatlestad

  For those of you who may have missed it, Peter Flies, Principal Technical Support Engineer for WebCenter Content, gave an excellent webcast on database searching and indexing in WebCenter Content.  It's available for replay along with a download of the slidedeck.  Look for the one titled 'WebCenter Content: Database Searching and Indexing'. One of the items he led with...and concluded with...was a recommendation on optimizing your search collection if you are using full-text searching with the Oracle database.  This can greatly improve your search performance.  And this would apply to both Oracle Text Search and DATABASE.FULLTEXT search methods.  Peter describes how a collection can become fragmented over time as content is added, updated, and deleted.  Just like you should defragment your hard drive from time to time to get your files placed on the disk in the most optimal way, you should do the same for the search collection. And optimizing the collection is just a simple procedure call that can be scheduled to be run automatically.   [Read more]

And just as a reminder, be sure to involve your DBA with your WebCenter Content implementation as you go to production and over time.  We recently had a customer complain of slow performance of the application when it was discovered the database was starving for memory.  So it's always helpful to keep a watchful eye on your database.

• How to set conditional activation to taskflows?

  - by shantala.sankeshwar(at)oracle.com

  This article describes implementing conditional activation to taskflows.Use Case Description Suppose we have a taskflow dropped as region on a page & this region is enclosed in a popup .By default when the page is loaded the respective region also gets loaded.Hence a region model needs to provide a viewId whenever one is requested.  A consequence of this is the TaskFlowRegionModel always has to initialize its task flow and execute the task flow's default activity in order to determine a viewId, even if the region is not visible on the page.This can lead to unnecessary performance overhead of executing task flow to generate viewIds for regions that are never visible. In order to increase the performance,we need to set the taskflow bindings activation property to 'conditional'.Below described is a simple usecase that shows how exactly we can set the conditional activations to taskflow bindings.Steps:1.Create an ADF Fusion web ApplicationView image 2.Create Business components for Emp tableView image3.Create a view criteria where deptno=:some_bind_variableView image4.Generate EmpViewImpl.java file & write the below code.Then expose this to client interface.    public void filterEmpRecords(Number deptNo){            // Code to filter the deptnos         ensureVariableManager().setVariableValue("some_bind_variable",  deptNo);        this.applyViewCriteria(this.getViewCriteria("EmpViewCriteria"));        this.executeQuery();       }5.Create an ADF Taskflow with page fragements & drop the above method on the taskflow6.Also drop the view activity(showEmp.jsff) .Define control flow case from the above method activity to the view activity.Set the method activity as default activityView image7.Create  main.jspx page & drop the above taskflow as region on this pageView image8.Surround the region with the dialog & surround the dialog with the popup(id is Popup1)9.Drop the commandButton on the above page & insert af:showPopupBehavior inside the commandButton:<af:commandButton text="show popup" id="cb1"><af:showPopupBehavior popupId="::Popup1"/></af:commandButton>10.Now if we execute this main page ,we will notice that the method action gets called even before the popup is launched.We can avoid this this by setting the activation property of the taskflow to conditional11.Goto the bindings of the above main page & select the taskflow binding ,set its activation property to 'conditional' & active property to Boolean value #{Somebean.popupVisible}.By default its value should be false.View image12.We need to set the above Boolean value to true only when the popup is launched.This can be achieved by inserting setPropertyListener inside the popup:<af:setPropertyListener from="true" to="#{Somebean.popupVisible}" type="popupFetch"/>13.Now if we run the page,we will notice that the method action is not called & only when we click on 'show popup' button the method action gets called.

• Introducing the Oracle MDM Blog - Why All MDM Solutions Aren't Equal

  - by ken.pulverman

  Welcome to the Oracle MDM Blog.  Dave Butler, Tony Ouk, and myself - Ken Pulverman, will be bringing you news and information from the world of MDM at Oracle.  Dave is our resident expert with more than 30 years of experience in data and information management. Tony has deep expertise in our Exadata product line which provides a strong hardware synergy with MDM.  I come from Siebel Systems where I helped found the team that built our integration product line and then our Universal Customer Master with is part of our MDM offering at Oracle. I thought I'd hit the ground running with a topic we are going to want to continue to bend your ear about.  We had a recent meeting with Ford Goodman, our head of MDM commercial sales in the US and he was very fired up about and important topic.  He's irked that all MDM solutions get painted with the same brush even though they aren't the same at all. There are companies out there trying to represent frameworks and toolkits as out of the box solutions.  They give you the pleasure (read pain) of doing things like developing your own multi-application data model, building your own web services, or creating your own APIs.  Huh?  What gets sold as flexibility in reality is a barrier to ever going live.  At Siebel Systems we obsessed over the notion of a customer.  Our data model took over 10 years to perfect as defining a customer is a very complex task indeed.  There are divisions, subsidiaries, branches, acquisitions, sites etc., etc., etc..  You'll want to do your homework, but trust me - you aren't going to want to take the time or resource to build these canonical data structures yourself.  And what about APIs?  Again, it sounds flexible.  In reality it's a lot of work. Our DNA at Oracle is to reduce the cost of information technology so we pre-integrate our technology with all of our major applications and pre-build integrations and connectors for all the major systems you work with.  This is tedious work that requires detailed knowledge of the interfaces of all the applications involved.  It is also version specific as the interface features and technology are always changing.  We have a substantial organization to manage this complexity so you don't have to.  Suffice to say, we'd like to help our customers peel back the rhetoric of companies that fly the MDM flag without a real offering that you can quickly benefit from. Please watch this space for more information on this storyline as well as news and information around Oracle MDM.

• Easier ASP.NET MVC Routing

  - by Steve Wilkes

  I've recently refactored the way Routes are declared in an ASP.NET MVC application I'm working on, and I wanted to share part of the system I came up with; a really easy way to declare and keep track of ASP.NET MVC Routes, which then allows you to find the name of the Route which has been selected for the current request. Traditional MVC Route Declaration Traditionally, ASP.NET MVC Routes are added to the application's RouteCollection using overloads of the RouteCollection.MapRoute() method; for example, this is the standard way the default Route which matches /controller/action URLs is created: routes.MapRoute(     "Default",     "{controller}/{action}/{id}",     new { controller = "Home", action = "Index", id = UrlParameter.Optional }); The first argument declares that this Route is to be named 'Default', the second specifies the Route's URL pattern, and the third contains the URL pattern segments' default values. To then write a link to a URL which matches the default Route in a View, you can use the HtmlHelper.RouteLink() method, like this: @ this.Html.RouteLink("Default", new { controller = "Orders", action = "Index" }) ...that substitutes 'Orders' into the {controller} segment of the default Route's URL pattern, and 'Index' into the {action} segment. The {Id} segment was declared optional and isn't specified here. That's about the most basic thing you can do with MVC routing, and I already have reservations: I've duplicated the magic string "Default" between the Route declaration and the use of RouteLink(). This isn't likely to cause a problem for the default Route, but once you get to dozens of Routes the duplication is a pain. There's no easy way to get from the RouteLink() method call to the declaration of the Route itself, so getting the names of the Route's URL parameters correct requires some effort. The call to MapRoute() is quite verbose; with dozens of Routes this gets pretty ugly. If at some point during a request I want to find out the name of the Route has been matched.... and I can't. To get around these issues, I wanted to achieve the following: Make declaring a Route very easy, using as little code as possible. Introduce a direct link between where a Route is declared, where the Route is defined and where the Route's name is used, so I can use Visual Studio's Go To Definition to get from a call to RouteLink() to the declaration of the Route I'm using, making it easier to make sure I use the correct URL parameters. Create a way to access the currently-selected Route's name during the execution of a request. My first step was to come up with a quick and easy syntax for declaring Routes. 1 . An Easy Route Declaration Syntax I figured the easiest way of declaring a route was to put all the information in a single string with a special syntax. For example, the default MVC route would be declared like this: "{controller:Home}/{action:Index}/{Id}*" This contains the same information as the regular way of defining a Route, but is far more compact: The default values for each URL segment are specified in a colon-separated section after the segment name The {Id} segment is declared as optional simply by placing a * after it That's the default route - a pretty simple example - so how about this? routes.MapRoute(     "CustomerOrderList",     "Orders/{customerRef}/{pageNo}",     new { controller = "Orders", action = "List", pageNo = UrlParameter.Optional },     new { customerRef = "^[a-zA-Z0-9]+$", pageNo = "^[0-9]+$" }); This maps to the List action on the Orders controller URLs which: Start with the string Orders/ Then have a {customerRef} set of characters and numbers Then optionally a numeric {pageNo}. And again, it’s quite verbose. Here's my alternative: "Orders/{customerRef:^[a-zA-Z0-9]+$}/{pageNo:^[0-9]+$}*->Orders/List" Quite a bit more brief, and again, containing the same information as the regular way of declaring Routes: Regular expression constraints are declared after the colon separator, the same as default values The target controller and action are specified after the -> The {pageNo} is defined as optional by placing a * after it With an appropriate parser that gave me a nice, compact and clear way to declare routes. Next I wanted to have a single place where Routes were declared and accessed. 2. A Central Place to Declare and Access Routes I wanted all my Routes declared in one, dedicated place, which I would also use for Route names when calling RouteLink(). With this in mind I made a single class named Routes with a series of public, constant fields, each one relating to a particular Route. With this done, I figured a good place to actually declare each Route was in an attribute on the field defining the Route’s name; the attribute would parse the Route definition string and make the resulting Route object available as a property. I then made the Routes class examine its own fields during its static setup, and cache all the attribute-created Route objects in an internal Dictionary. Finally I made Routes use that cache to register the Routes when requested, and to access them later when required. So the Routes class declares its named Routes like this: public static class Routes{     [RouteDefinition("Orders/{customerName}->Orders/Index")]     public const string OrdersCustomerIndex = "OrdersCustomerIndex";     [RouteDefinition("Orders/{customerName}/{orderId:^([0-9]+)$}->Orders/Details")]     public const string OrdersDetails = "OrdersDetails";     [RouteDefinition("{controller:Home}*/{action:Index}*")]     public const string Default = "Default"; } ...which are then used like this: @ this.Html.RouteLink(Routes.Default, new { controller = "Orders", action = "Index" }) Now that using Go To Definition on the Routes.Default constant takes me to where the Route is actually defined, it's nice and easy to quickly check on the parameter names when using RouteLink(). Finally, I wanted to be able to access the name of the current Route during a request. 3. Recovering the Route Name The RouteDefinitionAttribute creates a NamedRoute class; a simple derivative of Route, but with a Name property. When the Routes class examines its fields and caches all the defined Routes, it has access to the name of the Route through the name of the field against which it is defined. It was therefore a pretty easy matter to have Routes give NamedRoute its name when it creates its cache of Routes. This means that the Route which is found in RequestContext.RouteData.Route is now a NamedRoute, and I can recover the Route's name during a request. For visibility, I made NamedRoute.ToString() return the Route name and URL pattern, like this: The screenshot is from an example project I’ve made on bitbucket; it contains all the named route classes and an MVC 3 application which demonstrates their use. I’ve found this way of defining and using Routes much tidier than the default MVC system, and you find it useful too
