  • Walmart and Fusion Apps

    - by ultan o'broin
    Photograph: Misha Vaughan I attended Fusion Apps (yes, I know I am supposed to say "Oracle Fusion Applications", but stuffy old style guides are a turn-off in interwebs conversations) User Experience Advocate (FXA) training in Long Beach, California last week; a suitable location as ODTUG KSCOPE 11 was kicking off and key players were in the area. As a member of Oracle's Apps-UX team I know the Fusion Apps messaging, natch, and done some other Fusion Apps go-to-market content work too. For the messaging details themselves, see Lonneke Dikmans (@lonnekedikmans) great blog, by the way. However, I wanted some 'formal' training combined with the opportunity to meet and learn from people already out there delivering those messages. The idea in me reaching out to Misha Vaughan, Apps-UX FXA maven, to get me onto this training was that in addition to my UX knowledge, I could leverage my location in EMEA and hit up customer events more quickly and easily. Those local user groups do like to hear the voice of locals too you know (so I need to work on that mid-Atlantic accent). I'm looking forward to such opportunities. The training was all smashing stuff, just the right level of detail, delivered professionally and with great style and humor. I was especially honored to be paired off for my er, coaching with Debra Lilley (@debralilley), who shared with everyone all kinds of tips and insights from her experiences of delivering the message and demo. For me, that was the real power of the FXA event--the communal, conversational aspect--the meeting up with people who had done all this for real, the sharing in their experiences, while learning along with other newbies. Sorry, but that all-important social aspect doesn't work so well with remote meetings. Katie Candland (Apps-UX) gave us a great tour of the Fusion Apps demo and included some useful presentational tips too (any excuse to buy that iPad). It's clear to me that the Fusion Apps messaging and demos really come alive with real-world examples that local application users will recognize, and I picked up some "yes, that's my job made easier" scene-stealers from Debra and Karen Brownfield too, to add to the great ones already provided. This power of examples shouldn't surprise anyone, they've long been a mainstay of applications user assistance, popular with users. We'll offer customers different types of example topics in the Fusion Apps online help too (stay tuned), and we know from research how important those 3S's (stories, scenarios, and simulations) are to users when they consume and apply information. Well, we've got the simulation, now it's time for more stories and scenarios. If you get a chance to participate in an FXA event (whether you are an Oracle employee or otherwise), I'd encourage it. It's committing your time and energy for sure, but I got real bang for the buck from it for my everyday job too. Listening to the room's feedback on the application demo really brought our internal design work to life, and I picked up on some things that I need to follow up on (like how you alphabetically sort stuff in other languages). User experience is after all, about users. What will I be doing next, and what would I like to see happen? Obviously, I need to develop my story-telling links with the people I met in Long Beach and do some practicing with the materials, and then get out there and deliver them at a suitable location. The demo is what it is right now, and that's a super-rich demo that I know everyone will want to see and ask questions about. Then, as mentioned by attendees at the FXA event, follow up on those translated and localized messages for EMEA (and APAC), that deal with different statutory or reporting requirements of the target markets. Given my background I would say that, wouldn't I? However, language is part of the UX, and international revenue is greater than US-only revenue for Oracle, so yes dear, we all need to get over the fact that enterprise apps users don't all speak, or want to speak, American-English. Most importantly perhaps, the continued development of a strong messaging community between Oracle and partners and customers where we can swap and share those FXA messaging stories and scenarios about Fusion Apps in a conversational way. The more the better, a combination of online and face-to-face meetings. I must also mention the great dinner after the event at Parker's Lighthouse, and the fun myself and Andrew Gilmour (Apps-UX) had at our end of the table talking about just about everything except Fusion Apps with Ronald Van Luttikhuizen and Ben Prusinski (who now understands the difference between Cork and Dublin people. I hope). Thanks to all the Apps-UXers who helped bring the FXA training to town, and to Debra and all the others that I am too jetlagged to mention right who were instrumental in making it happen for me. Here's to the next one. And the Walmart angle? That was me doing my Robert Scoble (ScO'bilizer?)-style guerilla smart phone research in Walmart in Long Beach, before the FXA event. It's all about stories for me. You can read more about it on the appslab blog (see the comments).

  • How to build a great relationship with your colleagues

How will you get along with them? What if they don’t like you? Have you ever felt you’re „the new guy” and your colleagues have already their own way of talking one to each other, their own jokes? It’s a common feeling and can actually become stressful. I am Norbert, Middleware Presales Intern in Hungary and I’ve been working within Oracle for only 1 month. Joining such a big company has been a challenge from many perspectives. One of them was adapting with the environment and getting to know all my colleagues. You know it’s quite difficult to introduce yourself, to try to liaise with them and find some common topics, so I felt very lucky and comfortable when my manager introduced me to all of my colleagues. It was easier to accommodate and we basically we had a starting point for our discussions. We started to talk about what my position means, for how many years they’ve been within Oracle, other Oracle related topics, but also more personal stuff like what they do after work. Having this opportunity of talking with all of them helped me introduce myself in a proper way and actually I told them many things about myself. Networking wasn’t my best skill, but these first days were really helpful from a network point of view. What else can you do to get along with your colleagues? One second thing I consider as being really helpful in networking is asking work-related questions. For instance, when you don’t know how to do something or don’t understand it, asking one of your colleagues will also help you to make a connection with him and you could easily continue the discussion with some other topics which are more personal. It’s a very effective strategy and in a company like Oracle people are very willing to help you with your tasks and perform at a high level. If you see your colleagues going to lunch, you should join them. It will help you become part of their community, finding out what’s new in their lives, you’ll, step-by-step, take part in their conversations and be up to date with the hot topics they talk about. One other opportunity of becoming part of your colleagues’ community are the internal events. Subscribing to the local free time activities mailing list is very useful for finding out information about when they’re going out and have a drink or attending all sorts of events. For instance, this is how I’ve found out about a party within Oracle that most of the employees here attend. It’s a wonderful opportunity for chatting and make a stronger connection to some of them. How important is attending these events? Think about how much time you spend at work. You’d like to enjoy your work and the environment, so getting along with your colleagues is a nice thing to have. I recently attended a corporate party whose purpose was to facilitate the interaction and communication between employees. It was a real success and we had a lot of fun, especially because it was a costume party.  All the fancy dresses and funny clothes we wore made the atmosphere really enjoyable. It was easy to liaise with colleague with whom I had never interacted with before. There was a friendly spirit among us, chatting about personal stuff and about various pleasant things. Working in an international company is not an easy thing because you interact with many people and they have different styles, but all these opportunities of informal interaction are a good way to adapt to the new working environment.

  • How to display a dependent list box disabled if no child data exist

    - by frank.nimphius
    A requirement on OTN was to disable the dependent list box of a model driven list of value configuration whenever the list is empty. To disable the dependent list, the af:selectOneChoice component needs to be refreshed with every value change of the parent list, which however already is the case as the list boxes are already dependent. When you create model driven list of values as choice lists in an ADF Faces page, two ADF list bindings are implicitly created in the PageDef file of the page that hosts the input form. At runtime, a list binding is an instance of FacesCtrlListBinding, which exposes getItems() as a method to access a list of available child data (java.util.List). Using Expression Language, the list is accessible with #{bindings.list_attribute_name.items} To dynamically set the disabled property on the dependent af:selectOneChoice component, however, you need a managed bean that exposes the following two methods //empty – but required – setter method public void setIsEmpty(boolean isEmpty) {} //the method that returns true/false when the list is empty or //has values public boolean isIsEmpty() {   FacesContext fctx = FacesContext.getCurrentInstance();   ELContext elctx = fctx.getELContext();   ExpressionFactory exprFactory =                          fctx.getApplication().getExpressionFactory();   ValueExpression vexpr =                       exprFactory.createValueExpression(elctx,                         "#{bindings.EmployeeId.items}",                       Object.class);   List employeesList = (List) vexpr.getValue(elctx);                        return employeesList.isEmpty()? true : false;      } If referenced from the dependent choice list, as shown below, the list is disabled whenever it contains no list data <! --  master list --> <af:selectOneChoice value="#{bindings.DepartmentId.inputValue}"                                  label="#{bindings.DepartmentId.label}"                                  required="#{bindings.DepartmentId.hints.mandatory}"                                   shortDesc="#{bindings.DepartmentId.hints.tooltip}"                                   id="soc1" autoSubmit="true">      <f:selectItems value="#{bindings.DepartmentId.items}" id="si1"/> </af:selectOneChoice> <! --  dependent  list --> <af:selectOneChoice value="#{bindings.EmployeeId.inputValue}"                                   label="#{bindings.EmployeeId.label}"                                      required="#{bindings.EmployeeId.hints.mandatory}"                                   shortDesc="#{bindings.EmployeeId.hints.tooltip}"                                   id="soc2" disabled="#{lovTestbean.isEmpty}"                                   partialTriggers="soc1">     <f:selectItems value="#{bindings.EmployeeId.items}" id="si2"/> </af:selectOneChoice>

  • Reading train stop display names from a resource bundle

To do so Double-click onto the bounded task flow configuration file (XML) located in the Application Navigator so the task flow diagram open In the task flow diagram, select the view activity node for which you want to define the display name. In the Structure Window., expand the view activity node and then the train-stop node therein Add the display name element by using the right-click context menu on the train-stop node, selecting Insert inside train-stop > Display Name Edit the Display Name value with the Property Inspector Following the steps outlined above, you can define static display names – like "PF1" for page fragment 1 shown in the image below - for train stops to show at runtime. In the following, I explain how you can change the static display string to a dynamic string that reads the display label from a resource bundle so train stop labels can be internationalized. There are different strategies available for managing message bundles within an Oracle JDeveloper project. In this blog entry, I decided to build and configure the default properties file as indicated by the projects properties. To learn about the suggested file name and location, open the JDeveloper project properties (use a right mouse click on the project node in the Application Navigator and choose Project Properties. Select the Resource Bundle node to see the suggested name and location for the default message bundle. Note that this is the resource bundle that Oracle JDeveloper would automatically create when you assign a text resource to an ADF Faces component in a page. For the train stop display name, we need to create the message bundle manually as there is no context menu help available in Oracle JDeveloper. For this, use a right mouse click on the JDeveloper project and choose New | General | File from the menu and in the opened dialog. Specify the message bundle file name as the name looked up before in the project properties Resource Bundle option. Also, ensure that the file is saved in a directory structure that matches the package structure shown in the Resource Bundle dialog. For example, you would save the properties file in the View Project's src > adf > sample directory if the package structure was "adf.sample" (adf.sample.ViewControllerBundle). Edit the properties file and define key – values pairs for the train stop component. In the sample, such key value pairs are TrainStop1=Train Stop 1 TrainStop2=Train Stop 2 TrainStop3=Train Stop 3 Next, double click the faces-config.xml file and switch the opened editor to the Overview tab. Select the Application category and press the green plus icon next to the Resource Bundle section. Define the resource bundle Base Name as the package and properties file name, for example adf.sample.ViewControllerBundle Finally, define a variable name for the message bundle so the bundle can be accessed from Expression Language. For this blog example, the name is chosen as "messageBundle". <resource-bundle>   <base-name>adf.sample.ViewControllerBundle</base-name>   <var>messageBundle</var> </resource-bundle> Next, select the display-name element in the train stop node (similar to when creating the display name) and use the Property Inspector to change the static display string to an EL expression referencing the message bundle. For example: #{messageBundle.TrainStop1} At runtime, the train stops now show display names read from a message bundle (the properties file).

  • Transparent Data Encryption

    Transparent Data Encryption is designed to protect data by encrypting the physical files of the database, rather than the data itself. Its main purpose is to prevent unauthorized access to the data by restoring the files to another server. With Transparent Data Encryption in place, this requires the original encryption certificate and master key. It was introduced in the Enterprise edition of SQL Server 2008. John Magnabosco explains fully, and guides you through the process of setting it up....Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • Right-Time Retail Part 2

What good is an immediate stock-out notification if the supply chain can’t react until tomorrow? Since being formed in 2006, Oracle Retail has been not only adding more integrations between systems, but also modernizing integrations for appropriate speed. Notice I tossed in the word “appropriate.” Not everything needs to be real-time – again, we’re talking about Right-Time Retail. The speed of data capture, analysis, and execution must be synchronized or you’re wasting effort. Unfortunately, there isn’t an enterprise-wide dial that you can crank-up for your estate. You’ll need to improve things piecemeal, with people and processes as limiting factors while choosing the appropriate types of integrations. There are three integration styles we see in the retail industry. First is batch. I know, the word “batch” just sounds slow, but this pattern is less about velocity and more about volume. When there are large amounts of data to be moved, you’ll want to use batch processes. Our technology of choice here is Oracle Data Integrator (ODI), which provides a fast version of Extract-Transform-Load (ETL). Instead of the three-step process, the load and transform steps are combined to save time. ODI is a key technology for moving data into Retail Analytics where we can apply science. Performing analytics on each sale as it occurs doesn’t make any sense, so we batch up a statistically significant amount and submit all at once. The second style is fire-and-forget. For some types of data, we want the data to arrive ASAP but immediacy is not necessary. Speed is less important than guaranteed delivery, so we use message-oriented middleware available in both Weblogic and the Oracle database. For example, Point-of-Service transactions are queued for delivery to Central Office at corporate. If the network is offline, those transactions remain in the queue and will be delivered when the network returns. Transactions cannot be lost and they must be delivered in order. (Ever tried processing a return before the sale?) To enhance the standard queues, we offer the Retail Integration Bus (RIB) to help the management and monitoring of fire-and-forget messaging in the enterprise. The third style is request-response and is most commonly implemented as Web services. This is a synchronous message where the sender waits for a response. In this situation, the volume of data is small, guaranteed delivery is not necessary, but speed is very important. Examples include the website checking inventory, a price lookup, or processing a credit card authorization. The Oracle Service Bus (OSB) typically handles the routing of such messages, and we’ve enhanced its abilities with the Retail Service Backbone (RSB). To better understand these integration patterns and where they apply within the retail enterprise, we’re providing the Retail Reference Library (RRL) at no charge to Oracle Retail customers. The library is composed of a large number of industry business processes, including those necessary to support Commerce Anywhere, as well as detailed architectural diagrams. These diagrams allow implementers to understand the systems involved in integrations and the specific data payloads. Furthermore, with our upcoming release we’ll be providing a new tool called the Retail Integration Console (RIC) that allows IT to monitor and manage integrations from a single point. Using RIC, retailers can quickly discern where integration activity is occurring, volume statistics, average response times, and errors. The dashboards provide the ability to dive down into the architecture documentation to gather information all the way down to the specific payload. Retailers that want real-time integrations will also need real-time monitoring of those integrations to ensure service-level agreements are maintained. Part 3 looks at marketing.

  • ADF Reusable Artefacts

    - by Arda Eralp
    Primary reusable ADF Business Component: Entity Objects (EOs) View Objects (VOs) Application Modules (AMs) Framework Extensions Classes Primary reusable ADF Controller: Bounded Task Flows (BTFs) Task Flow Templates Primary reusable ADF Faces: Page Templates Skins Declarative Components Utility Classes Certain components will often be used more than once. Whether the reuse happens within the same application, or across different applications, it is often advantageous to package these reusable components into a library that can be shared between different developers, across different teams, and even across departments within an organization. In the world of Java object-oriented programming, reusing classes and objects is just standard procedure. With the introduction of the model-view-controller (MVC) architecture, applications can be further modularized into separate model, view, and controller layers. By separating the data (model and business services layers) from the presentation (view and controller layers), you ensure that changes to any one layer do not affect the integrity of the other layers. You can change business logic without having to change the UI, or redesign the web pages or front end without having to recode domain logic. Oracle ADF and JDeveloper support the MVC design pattern. When you create an application in JDeveloper, you can choose many application templates that automatically set up data model and user interface projects. Because the different MVC layers are decoupled from each other, development can proceed on different projects in parallel and with a certain amount of independence. ADF Library further extends this modularity of design by providing a convenient and practical way to create, deploy, and reuse high-level components. When you first design your application, you design it with component reusability in mind. If you created components that can be reused, you can package them into JAR files and add them to a reusable component repository. If you need a component, you may look into the repository for those components and then add them into your project or application. For example, you can create an application module for a domain and package it to be used as the data model project in several different applications. Or, if your application will be consuming components, you may be able to load a page template component from a repository of ADF Library JARs to create common look and feel pages. Then you can put your page flow together by stringing together several task flow components pulled from the library. An ADF Library JAR contains ADF components and does not, and cannot, contain other JARs. It should not be confused with the JDeveloper library, Java EE library, or Oracle WebLogic shared library. Reusable Component Description Data Control Any data control can be packaged into an ADF Library JAR. Some of the data controls supported by Oracle ADF include application modules, Enterprise JavaBeans, web services, URL services, JavaBeans, and placeholder data controls. Application Module When you are using ADF Business Components and you generate an application module, an associated application module data control is also generated. When you package an application module data control, you also package up the ADF Business Components associated with that application module. The relevant entity objects, view objects, and associations will be a part of the ADF Library JAR and available for reuse. Business Components Business components are the entity objects, view objects, and associations used in the ADF Business Components data model project. You can package business components by themselves or together with an application module. Task Flows & Task Flow Templates Task flows can be packaged into an ADF Library JAR for reuse. If you drop a bounded task flow that uses page fragments, JDeveloper adds a region to the page and binds it to the dropped task flow. ADF bounded task flows built using pages can be dropped onto pages. The drop will create a link to call the bounded task flow. A task flow call activity and control flow will automatically be added to the task flow, with the view activity referencing the page. If there is more than one existing task flow with a view activity referencing the page, it will prompt you to select the one to automatically add a task flow call activity and control flow. If an ADF task flow template was created in the same project as the task flow, the ADF task flow template will be included in the ADF Library JAR and will be reusable. Page Templates You can package a page template and its artifacts into an ADF Library JAR. If the template uses image files and they are included in a directory within your project, these files will also be available for the template during reuse. Declarative Components You can create declarative components and package them for reuse. The tag libraries associated with the component will be included and loaded into the consuming project. You can also package up projects that have several different reusable components if you expect that more than one component will be consumed. For example, you can create a project that has both an application module and a bounded task flow. When this ADF Library JAR file is consumed, the application will have both the application module and the task flow available for use. You can package multiple components into one JAR file, or you can package a single component into a JAR file. Oracle ADF and JDeveloper give you the option and flexibility to create reusable components that best suit you and your organization. You create a reusable component by using JDeveloper to package and deploy the project that contains the components into a ADF Library JAR file. You use the components by adding that JAR to the consuming project. At design time, the JAR is added to the consuming project's class path and so is available for reuse. At runtime, the reused component runs from the JAR file by reference.

  • R: How can I use apply on rows of a data.frame and get out $column_name?

    - by John
    I'm trying to access $a using the following example: df<-data.frame(a=c("x","x","y","y"),b=c(1,2,3,4)) > df a b 1 x 1 2 x 2 3 y 3 4 y 4 test_fun <- function (data.frame_in) { print (data.frame_in[1]) } I can now access $a if I use an index for the first column: apply(df, 1, test_fun) a "x" a "x" a "y" a "y" [1] "x" "x" "y" "y" But I cannot access column $a with the $ notation: error: "$ operator is invalid for atomic vectors" test_fun_2 <- function (data.frame_in) { print (data.frame_in$a) } >apply(df, 1, test_fun_2) Error in data.frame_in$a : $ operator is invalid for atomic vectors Is this not possible?

  • Using one data source across multiple views in Kendo UI SPA

    - by user3731783
    I am trying to build a Kendo UI SPA. I have two views. View 1 (appListView) shows Application Details in a grid and view 2 (activityView) will have a dropdown for application names and a grid that shows the activity for selected application As I am loading all the application details on the loading of view 1, I would like to re-use those details to populate the dropdown on view 2. Please see my code below. Everything works fine but when I go to View 2 it makes a call to the service again to get application details. I would like to use the existing data if it is already loaded and if the uses comes to view 2 directly then it should get application data also. I am not sure what I am missing in the code. View Markup: <script id="appListView" type="text/x-kendo-template"> <h3 data-bind="html: displayName"></h3> <div data-role="grid" data-editable="{'mode':'popup'}" data-bind="source: items" data-columns="[ {'field': 'Name'}, {'field': 'ContactEmail','title':'Contact Email'} ]"> </div> </script> <script id="" type="text\x-kendo-template"> <div> Activity for Application&nbsp;&nbsp; <input name="AppName" data-role="dropdownlist" data-source="appsModel.items" data-text-field="Name" data-value-field="Id" data-option-label="Choose an application name" style="width:250px;" /> </div> <div id="Activities" data-role="grid" data-bind="source: items" data-auto-bind="false" data-columns="[ {'field': 'Domain','title':'Domain'}, {'field': 'ActivityType','title':'Activity Type'} ]"> </div> </script> js with DataSource and View Model: //data sources var applications = new kendo.data.DataSource({ schema: { model: { id: "Id" } }, serverFiltering : true, transport: { read: { url: '/api/App', dataType: 'json', type:'GET' } } }); var activities = new kendo.data.DataSource({ schema: { model: { id: "Id" } }, transport: { read: { url: '/api/Activity', dataType: 'json', type: 'GET' }, parameterMap: function (data, type) { if (type == "read") { return 'appId=' + $("#AppName").val() ; } } } }); //Models var appsModel = kendo.observable({ items: applications, displayName: 'My Applications' }); var activityModel = kendo.observable({ items: activities, onAppChange: function(t){ $("#Activities").data("kendoGrid").dataSource.read(); }, dispayName: 'Application Activities' }); //views var layout = new kendo.Layout("layout-template"); var appListView = new kendo.View("appListView", { model: appsModel }); var activityView = new kendo.View("activityView", { model: activityModel }); Thank you for taking time to read this long question.

  • Importing Data from Google Analytics

    - by Adam Tannon
    I am planning on building a web app with many different public-facing HTTP servers; each of which will have Google Analytics (GA) installed on them. I'd like to create a "dashboard" app that consolidates the GA data into one screen. I've been perusing the documentation for this so-called GA API, but I can't tell what the end result of the GA API is: Does the GA API allow me to do exactly what I am looking for it to do? Or... Does the GA API do something entirely different (like allow me to share my data with Google+ or something else weird) Since an API can be used to CRUD any kind of data, I guess I'm asking which way the GA API goes: is it for querying (reading) data from 1+ server instances, or is it for modifying data on those servers or somewhere else? Thanks in advance!

  • Displaying a Sorted, Paged, and Filtered Grid of Data in ASP.NET MVC

    Over the past couple of months I've authored five articles on displaying a grid of data in an ASP.NET MVC application. The first article in the series focused on simply displaying data. This was followed by articles showing how to sort, page, and filter a grid of data. We then examined how to both sort and page a single grid of data. This article looks at how to add the final piece to the puzzle: we'll see how to combine sorting, paging and filtering when displaying data in a single grid. Like with its predecessors, this article offers step-by-step instructions and includes a complete, working demo available for download at the end of the article. Read on to learn more! Read More >

  • Validating Column Data Stored as CSV Against Another Table

    - by Jakkwylde
    I wanted to see what some suggested approaches would be to validate a field that is stored as a CSV against a table containing appropriate values. Althought it would be desired, it is NOT an option to split the CSV list into another related table. In the example data below I would be trying to capture the code 99 for widget A. Below is an example data representation. Table: Widgets WidgetName WidgetCodeList A 1, 2, 3 B 1 C 2, 3 D 99 Table: WidgetCodes WidgetCode 1 2 3 An earlier approach was to query the CSV column as rows using various string manipulations and CONNECT_BY_LEVEL however the performance was not acceptible.

Java’s platform independence, high level of functionality, security, and developer productivity, address the key pain points in building embedded solutions... and that’s not just our opinion. Take a look at the new IDC report on Oracle’s stewardship of Java, “Java: Two and a half Years After the Acquisition” (doc #236309, August 2012). Java already powers around 3 billion devices worldwide, with traditional desktops and servers being only a small portion of that, and the ‘Internet of Things‘ is just really starting to explode. It is estimated that within five years, intelligent and connected embedded devices will outnumber desktops and mobile phones combined, and will generate the majority of the traffic on the Internet. Is your platform and services strategy ready for the coming disruptions and opportunities? It should come as no surprise that Oracle is enthusiastically focused on Java for Embedded .  New this year, Oracle is demonstrating its further commitment to the embedded marketplace by offering, for the first time, a dedicated conference focused on the business aspects of embedded Java: Java Embedded @ JavaOne. Co-located with the technically-focused JavaOne conference, Java Embedded @ JavaOne will run for two days in San Francisco targeting C-level executives, architects, business leaders, and decision makers. With 24 inspired business sessions with expert speakers from 18 prominent companies driving the next generation of Java Embedded business solutions (such as Cinterion, ARM, Hitachi and Rockwell Automation), attendees will learn how Java Embedded technologies and solutions can offer compelling value and a clear path forward to business efficiency and agility. You’ll also see how Oracle’s comprehensive technology portfolio can deliver a complete ‘Machine to Machine’ platform, from device to datacenter, resulting in a highly secure, resilient, high-performance and cost-effective solution. Seating is limited and we expect a lot of interest in this new event, so please register now! Note that if you are already attending the Oracle OpenWorld or JavaOne conferences, you can attend this conference for only $100 more. Watch my video below to find out more. I hope to see you there!

  • Cloud Deployment Models

    - by B R Clouse
    Normal 0 false false false EN-US X-NONE X-NONE As the cloud paradigm grows in depth and breadth, more readers are approaching the topic for the first time, or from a new perspective.  This blog is a basic review of  cloud deployment models, to help orient newcomers and neophytes. Most cloud deployments today are either private or public. It is also possible to connect a private cloud and a public cloud to form a hybrid cloud. A private cloud is for the exclusive use of an organization. Enterprises, universities and government agencies throughout the world are using private clouds. Some have designed, built and now manage their private clouds. Others use a private cloud that was built by and is now managed by a provider, hosted either onsite or at the provider’s datacenter. Because private clouds are for exclusive use, they are usually the option chosen by organizations with concerns about data security and guaranteed performance. Public clouds are open to anyone with an Internet connection. Because they require no capital investment from their users, they are particularly attractive to companies with limited resources in less regulated environments and for temporary workloads such as development and test environments. Public clouds offer a range of products, from end-user software packages to more basic services such as databases or operating environments. Public clouds may also offer cloud services such as a disaster recovery for a private cloud, or the ability to “cloudburst” a temporary workload spike from a private cloud to a public cloud. These are examples of a hybrid cloud. These are most feasible when the private and public clouds are built with similar technologies. Usually people think of a public cloud in terms of a user role, e.g., “Which public cloud should I consider using?” But someone needs to own and manage that public cloud. The company who owns and operates a public cloud is known as a public cloud provider. Oracle Database Cloud Service, Amazon RDS, database.com and Savvis Symphony Database are examples of public cloud database services.

Some workloads may be best-suited for a private cloud, some for a public or hybrid cloud. And you might deploy multiple private clouds in your organization. If you are going to combine multiple clouds, then you want to make sure that each cloud is based on a consistent technology portfolio and architecture. This simplifies management and gives you the greatest flexibility in moving resources and workloads among your different clouds. Oracle’s portfolio of cloud products and services enables both deployment models. Oracle can manage either model. Universities, government agencies and companies in all types of business everywhere in the world are using clouds built with the Oracle portfolio. By employing a consistent portfolio, these customers are able to run all of their workloads – from test and development to the most mission-critical -- in a consistent manner: One Enterprise Cloud, powered by Oracle.   /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}

  • How to implement Self-host WCF data serivces (http://localhost:1234/myDataService.svc/...)

    - by warmcold
    I have a project that needs to implement WCF data services (OData) to retrieve data from a control system (.NET Framework Application). The WCF data service needs to be hosted by the .NET application (No ASP.NET and NO IIS). I have seen many WCF Data Service examples recently; they are all hosted by ASP.NET application. I also see the self-host (console application) examples, but it is for WCF Service (not WCF Data Service). Here is my question: It is possible to have a standalone .NET Applications to host WCF Data Services ((http://localhost:1234/mydataservice.svc/...). If yes, can someone provide an example? Thanks.

  • How to store and update data table on client side (iOS MMO)

    - by farseer2012
    Currently i'm developing an iOS MMO game with cocos2d-x, that game depends on many data tables(excel file) given by the designers. These tables contain data like how much gold/crystal will be cost when upgrade a building(barracks, laboratory etc..). We have about 10 tables, each have about 50 rows of data. My question is how to store those tables on client side and how to update them once they have been modified on server side? My opinion: use Sqlite to store data on client side, the server will parse the excel files and send the data to client with JSON format, then the client parse the JOSN string and save it to Sqlite file. Is there any better method? I find that some game stores csv files on client side, how do they update the files? Could server send a whole file directly to client?

    Here is your chance to get your picture on the big screen during my MIX11 presentation in April this year. I need to create a small repository of sample data for my demos. So instead of tapping in my imagination and creating dummy users (or reusing past information I already used in other demos), I thought I would appeal to the amazing community: Send me an email with the following information. I will include the first 30 users into my sample data repository and use your info in my demo. First Name Last Name Date of birth Picture Link to Facebook profile (optional) Disclaimer: The data will only be running locally on my hard drive. The demos will however be filmed and the videos made public. By providing this information, you explicitly consent to this data being used in demos at MIX11 and possibly in following conferences. The data will only be used for demo purposes. Thanks for your help!!   Laurent Bugnion (GalaSoft) Subscribe | Twitter | Facebook | Flickr | LinkedIn

  • Using VBA to model data in Autodesk Inventor?

    - by user108478
    I have a close friend who is using a specific device that records the dimensions of an object as it is eroded and outputs the dimensional data to an excel sheet. The object is spherical in nature but is eroded from the top and bottom, so the shape is constantly changing and a single formula for surface area and volume would not work. This is where Inventor comes in. My friend can plug the dimensional data to Inventor and it immediately returns the surface area and volume. The erosion process takes several minutes to complete and records data at very short intervals, so it would be very arduous to plug in the data thousand of time. Since Inventor supports macros and VBA, is there a way to plug the data into Inventor and output it into another spreadsheet? Any suggestions would be appreciated.

At the beginning you think it’s easy, but when it’s your turn, you realize that actually it’s not as easy as you thought it would be. Especially nowadays, when we’re living difficult times and finding a job is a challenge. This is why I felt lucky when I joined Oracle. Do you want to know how did I do it? My name is Markéta Kocová and I am working as a Customer Intelligence Support Intern within Oracle Prague. Before this job I have, I was focused on my studies, going also abroad for one semester in Rostock University in Germany. I decided though to gain some working experience. In November 2011, I joined Oracle, this one being my first job. I never thought I would be part of such a big company, but here I am! I have to say that I think it’s quite difficult to find a job and thus job search might be exhausting. What did help me? I think it was the networking. The more people you know, the more chances you have to find a job. This is how I’ve heard about this internship. I think internship programs are a great opportunity for young people to gain experience and also to start building a career. As companies are looking for the candidates with the best skills and some experience, it’s difficult to get a job. It’s a paradox isn’t it? You are applying for a entry-level position, but you won’t get it because they’ll be searching for someone who has experience. This is why internship is a good solution to improve your skills. You will learn many things, you might get a mentor and also perform given tasks. What else could you do? In my opinion you should invest in yourself. Try to focus on both education and skills. In order to get a good job in an international and successful company, it’s not enough a university diploma. You could learn a foreign language because it’s usually required. Employers are also looking for good computer skills, so this could be something you could take into consideration before applying to a job. There are also some personal characteristics like communication abilities, self-reliance, self-confidence or ability to solve the crisis situations that companies look at when hiring a person. You could consider attending some training in order to improve these soft skills. Getting a job is difficult, but also when you make it and get one you’ll still finding challenging to stay there. You might realize it is not the dream job, but being patient and trying to learn as much as possible will help you to achieve more. I think every experience is valuable. I’ve been through this type of situation, but the environment, my colleagues and the atmosphere in office have always been great and made me love my job! Thanks guys!
