• Openmatics Revolutionizes Fleet Management with Standards-Based Vehicle Telematics Platform

  - by Michael Snow

  Openmatics s.r.o. was founded in 2010 as a subsidiary of ZF Friedrichshafen AG, a global player in driveline and chassis technology. Oracle Customer:  Openmatics s.r.o.Location:  Pilsen, Czech RepublicIndustry:  AutomotiveEmployees:  70 Its goal was to develop and operate a flexible, open telematics platform for automotive applications, which is independent from vehicle and component suppliers—recognizing that the fragmented telematics market was not meeting today’s fleet management needs. Openmatics provides a rich product portfolio, and customers can extend the platform, as required, to meet their needs. Partners and third-parties can develop their own applications using the Openmatics’ software development kit and can sell them via the Openmatics app shop.ZF Friedrichshafen AG is a global player in driveline and chassis technology. With 121 production companies and 650 service partners in 26 countries, ZF is among the top 10 largest automotive suppliers worldwide. Founded in 1915 to develop and produce transmissions for airships and vehicles, the group’s product offerings now include transmissions and steering systems as well as chassis components and complete axle systems and modules.  A word from Openmatics s.r.o.  “Oracle WebCenter Portal, together with the underlying Oracle Application Development Framework, provided the fundamental infrastructure for the Openmatics platform. Fleet managers can now reduce fuel consumption and operating costs, and more efficiently manage vehicle usage, maintenance, and safety. The standards-based platform allows third-party suppliers to deploy their own vehicle telematics services as Openmatics apps and creates a de facto standard for the automotive industry, independent from a single manufacturer or service provider.” – Gero Strobel, Head of Development, Openmatics s.r.o. Challenges Create an industry standard for vehicle telematics by establishing a customizable platform that enables access to telematics information, such as current and past fuel consumption, through a web browser to better meet automotive market and customer needs Reduce fleet-management costs by eliminating the need to invest in isolated telematics hardware and software solutions per vehicle brand and vehicle component manufacturer Establish an open platform where third-party providers—such as original equipment manufacturers (OEM), insurers, fleet operators, and individual developers—can deploy their own vehicle telematics services Allow users to purchase targeted telematics services as single apps to reduce costs and ensure rapid growth of telematics services available on the platform Enable users to configure their telematics apps with ease to make sure the platform meets individual fleet management requirements, such as analyzing past and current fuel consumption of a truck fleet Solutions Deployed Oracle WebCenter Portal as a foundation for Openmatics, a standards-based automotive telematics platform that provides next-generation fleet management with unified digital communication from and to vehicles on the move Used Oracle Application Development Framework as the development framework for Oracle WebCenter Portal’s components and services, providing developers with ready-to-use software development kits with application programming interfaces, design templates, and visual tools that accelerated time to market Used Oracle Enterprise Pack for Eclipse to simplify telematics application development in Java Enabled fleet monitoring by recording vehicle data—such as fuel consumption information—through onboard units, delivering the information to Oracle Database, and making it accessible through a customizable app portfolio on any web browser Stored vehicle telematics data—sent as encrypted information—in Oracle Database, ensuring data integrity and immediate availability for the platform’s telematics applications Enabled a wide range of telematics services suppliers, from vehicle component manufacturers to fleet application developers, to offer vehicle telematics services on the Openmatics platform, ensuring platform independence from OEMs Provided Openmatics customers with the means to individually select the automotive telematics services that are relevant to their business requirements, eliminating the need to pay for superfluous information and reducing fleet management costs Oracle Products & Services Oracle Application Development Framework Oracle WebCenter Portal Oracle SOA Suite Oracle Enterprise Pack for Eclipse Oracle Database Oracle Consulting &amp;amp;amp;amp;amp;amp;amp;&amp;amp;amp;amp;amp;lt;span id=&amp;amp;amp;amp;amp;quot;XinhaEditingPostion&amp;amp;amp;amp;amp;quot;&amp;amp;amp;amp;amp;gt;&amp;amp;amp;amp;amp;lt;/span&amp;amp;amp;amp;amp;gt;amp;&amp;amp;amp;amp;amp;amp;lt;span id=&amp;amp;amp;amp;amp;amp;quot;XinhaEditingPostion&amp;amp;amp;amp;amp;amp;quot;&amp;amp;amp;amp;amp;amp;gt;&amp;amp;amp;amp;amp;amp;lt;/span&amp;amp;amp;amp;amp;amp;gt;lt;p&amp;amp;amp;amp;amp;amp;amp;amp;gt; &amp;amp;amp;amp;amp;amp;amp;amp;lt;/p&amp;amp;amp;amp;amp;amp;amp;amp;gt;

• Oracle performance problem

  - by jreid42

  We are using an Oracle 11G machine that is very powerful; has redundant storage etc. It's a beast from what I have been told. We just got this DB for a tool that when I first came on as a coop had like 20 people using, now its upwards of 150 people. I am the only one working on it :( We currently have a system in place that distributes PERL scripts across our entire data center essentially giving us a sort of "grid" computing power. The Perl scripts run a sort of simulation and report back the results to the database. They do selects / inserts. The load is not very high for each script but it could be happening across 20-50 systems at the same time. We then have multiple data centers and users all hitting the same database with this same approach. Our main problem with this is that our database is getting overloaded with connections and having to drop some. We sometimes have upwards of 500 connections. These are old perl scripts and they do not handle this well. Essentially they fail and the results are lost. I would rather avoid having to rewrite a lot of these as they are poorly written, and are a headache to even look at. The database itself is not overloaded, just the connection overhead is too high. We open a connection, make a quick query and then drop the connection. Very short connections but many of them. The database team has basically said we need to lower the number of connections or they are going to ignore us. Because this is distributed across our farm we cant implement persistent connections. I do this with our webserver; but its on a fixed system. The other ones are perl scripts that get opened and closed by the distribution tool and thus arent always running. What would be my best approach to resolving this issue? The scripts themselves can wait for a connection to be open. They do not need to act immediately. Some sort of queing system? I've been suggested to set up a few instances of a tool called "SQL Relay". Maybe one in each data center. How reliable is this tool? How good is this approach? Would it work for what we need? We could have one for each data center and relay requests through it to our main database, keeping a pipeline of open persistent connections? Does this make sense? Is there any other suggestions you can make? Any ideas? Any help would be greatly appreciated. Sadly I am just a coop student working for a very big company and somehow all of this has landed all on my shoulders (there is literally nobody to ask for help; its a hardware company, everybody is hardware engineers, and the database team is useless and in India) and I am quite lost as what the best approach would be? I am extremely overworked and this problem is interfering with on going progress and basically needs to be resolved as quickly as possible; preferably without rewriting the whole system, purchasing hardware (not gonna happen), or shooting myself in the foot. HELP LOL!

• Auto showing tips and closing popup when lost focus

  - by darkwindkey

  I have two elements: a TextBox, and a Popup, where the popup contains a tree view to show some tips according to text of TextBox. When the textBox got the KeyDown Event, the KeyDown directly executes pup.IsOpen=true to show the popup tips. However, I also want to show the popup tips when the mouse on clicking the TextBox, and auto closing the popups when the mouse click on any place (besides the TextBox and the TreeView in Popup). I have tried some cases but do not works fine. Case1: Add pup.IsOpen=true; in TextBox.PreviewMouseUp, the popup will stay opening, even if I click any other place in the window. Case2: Add pup.IsOpen=true in TextBox.PreviewMouseDown, the popup tips only shows on keep clicking the Mouse. Case3: Using CheckBox with Binding IsChecked to Popup.IsOpen works fine. but the tips is listed according to the content of the TextBox, therefore the checkbox is not editable for user... Here is my code now: <Window x:Class="popUpTesting.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="350" Width="525"> <Grid> <TextBox Name="SearchBox" HorizontalAlignment="Center" TextWrapping="Wrap" Text="TextBox" VerticalAlignment="Center" KeyDown="SearchBox_KeyDown" PreviewMouseUp="SearchBox_PreviewMouseUp" /> <Popup Placement="Bottom" AllowsTransparency="True" PopupAnimation="Fade" StaysOpen="false" x:Name="pup" PlacementTarget="{Binding ElementName=SearchBox}" IsOpen="False" > <Grid> <TreeView HorizontalAlignment="Left" Height="200" VerticalAlignment="Top" Width="200"> <TreeViewItem Header="A"> <TreeViewItem Header="A1"/> </TreeViewItem> <TreeViewItem Header="B"></TreeViewItem> <TreeViewItem Header="C"></TreeViewItem> <TreeViewItem Header="D"></TreeViewItem> </TreeView> </Grid> </Popup> </Grid> </Window> and the event functions: private void SearchBox_KeyDown(object sender, KeyEventArgs e) { pup.IsOpen = true; } private void SearchBox_PreviewMouseUp(object sender, MouseButtonEventArgs e) { pup.IsOpen = true; }

• How to convert number(16,10) to date in oracle

  - by Elad

  Hi, I'm trying to read the borland starteam application oracle database and I noticed that they represent their date as a number(16,10) column I think it is not timestamp or epoc. for instance, I have the number: 37137.4347569444, how can I read it as date? I saw that the database has a stored procedure. CONVERT_DATE: CREATE OR REPLACE procedure STARBASE.convert_date ( number_of_days IN integer , nDate OUT number) is nDateOffset number; CurrentDate date; Month integer; Day integer; year number; success boolean := false; bLeapYear boolean:=false; nDaysInMonths number; nLeapDays integer; fDate number (16,10); rgMonthDays number(5,0); begin select sysdate - number_of_days into CurrentDate from dual; nDateOffset := 693959; select to_number(substr((TO_CHAR (CurrentDate, 'MM-DD-YYYY')) , 1, 2), '99') - 1 into month from dual; select to_number(substr((TO_CHAR (CurrentDate, 'MM-DD-YYYY')) , 4, 2), '99') - 1 into day from dual; select to_number(substr((TO_CHAR (CurrentDate, 'MM-DD-YYYY')) , 7, 4), '9999') into year from dual; if ( mod(year , 4) = 0 ) and ( ( mod(year , 400) = 0) or ( mod(year , 100) < 0 )) then bLeapYear :=true; end if; nLeapDays := 0; if ( bLeapYear = true) and ( Day = 28) and ( Month = 1 ) then nLeapDays := 1; end if; select substr(to_char(last_day(CurrentDate) , 'DD-MM-YYYY') , 1 , 2) into nDaysInMonths from dual; if Month = 0 then rgMonthDays := 0; elsif Month = 1 then rgMonthDays := 31; elsif Month = 2 then rgMonthDays := 59; elsif Month = 3 then rgMonthDays := 90; elsif Month = 4 then rgMonthDays := 120; elsif Month = 5 then rgMonthDays := 151; elsif Month = 6 then rgMonthDays := 181; elsif Month = 7 then rgMonthDays := 212; elsif Month = 8 then rgMonthDays := 243; elsif Month = 9 then rgMonthDays := 273; elsif Month = 10 then rgMonthDays := 304; elsif Month = 11 then rgMonthDays := 334; elsif Month = 12 then rgMonthDays := 365; end if; nDate := Year*365 + Year/4 - Year/100 + Year/400 + rgMonthDays + Day + 1; if( Month < 2 ) and ( bLeapYear = true) then nDate := nDate - 1; end if; nDate := nDate - nDateOffset; exception when others then raise; end convert_date; I don't know how to use it. how can i read it anyway? Please help. thank you

• Fast user switching suddenly stopped working on my Windows XP Prof machine

  - by John

  When I start Win XP SP2 I get to the welcome screen with no user names displayed. I then press Alt+Ctrl+Del twice and type in the username and then am able to login to Windows. When I go to user accounts in Control Panel I get the error message cells.item(...) is null or not an object. When I go to computer administration and then local users and groups there are no users listed under users but the groups is listed. I did a windows repair with no luck. I tried doing restore points but it said they didn’t work. Please help? My wife and I have been using fast user switching on out computer for years with no problem. Beginning a few months ago, I started Win XP Prof one day I get to the welcome screen with no user names displayed. I then press Alt+Ctrl+Del twice and type in the username and then am able to login to Windows with an account of owner. When I go to user accounts in Control Panel I get the error message cells.item(...) is null or not an object. When I go to computer administration and then local users and groups there are no users listed under users but the groups are listed. I have done system point restores and imports of exports of the registry I take with import. I have tried everything under safe mode and it makes no difference. This followed a Microsoft update the night before as I left the computer on. I tried to do a restore point but all my restore points failed and could not backout the MS updates. I was working with a fellow from Microsoft and he had me do all kinds of things but to no avail. He seems to think a DLL file is corrupt but which one? Finally in desperation he sent me a new OS XP Prof SP3 disk and I installed it and it wiped my hard drive. Luckily I took an Acronis Image backup first so I easily restored my system. I do not want to do a fresh windows update as it is heavily customized and worked fine up to that point. This has been going on for months, Thanks John

• Drawing an arrow cursor on user dragging in XNA/MonoGame

  - by adrin

  I am writing a touch enabled game in MonoGame (XNA-like API) and would like to display a an arrow 'cursor' as user is making a drag gesture from point A to point B. I am not sure on how to correctly approach this problem. It seems that its best to just draw a sprite from A to B and scale it as required. This would however mean it gets stretched as user continues dragging gesture in one direction. Or maybe its better to dynamically render the arrow so it looks better?

• PHP MVC error handling, view display and user permissions

  - by cen

  I am building a moderation panel from scratch in a MVC approach and a lot of questions cropped up during development. I would like to hear from others how they handle these situations. Error handling Should you handle an error inside the class method or should the method return something anyway and you handle the error in controller? What about PDO exceptions, how to handle them? For example, let's say we have a method that returns true if the user exists in a table and false if he does not exist. What do you return in the catch statement? You can't just return false because then the controller assumes that everything is alright while the truth is that something must be seriously broken. Displaying the error from the method completely breaks the whole design. Maybe a page redirect inside the method? The proper way to show a view The controller right now looks something like this: include('view/header.php'); if ($_GET['m']=='something') include('view/something.php'); elseif ($_GET['m']=='somethingelse') include('view/somethingelse.php'); include('view/foter.php'); Each view also checks if it was included from the index page to prevent it being accessed directly. There is a view file for each different document body. Is this way of including different views ok or is there a more proper way? Managing user rights Each user has his own rights, what he can see and what he can do. Which part of the system should verify that user has the permission to see the view, controller or view itself? Right now I do permission checks directly in the view because each view can contain several forms that require different permissions and I would need to make a seperate file for each of them if it was put in the controller. I also have to re-check for the permissions everytime a form is submitted because form data can be easily forged. The truth is, all this permission checking and validating the inputs just turns the controller into a huge if/then/else cluster. I feel like 90% of the time I am doing error checks/permissions/validations and very little of the actual logic. Is this normal even for popular frameworks?

• Running Teamsite User Admin tool IWUSERADM.exe from ASP.NET

  - by Narendra Tiwari

  It has really been a head scratching task for me. I 've tried many options but nothing worked. Finally I found a workaround on google to achive this by TaskScheduler. PROBLEM When we run Teamsite user administration command line tool IWUSERADM.exe though ASP.Net it gives following error: Application popup: cmd.exe - Application Error : The application failed to initialize properly (0xc0000142). Click on OK to terminate the application. CAUSE No specific cause, it seems to be a bug, supposed to be resolved with this Microsoft patch http://support.microsoft.com/kb/960266. and there is nothing related to permission issue, y web application is impersonated with an administrator account. off course running a bat file from dmin account is a potential secury threat but for this scenario lets conifned our discussion to run the command line tool. RESOLUTION I have not tried this patch as I have not permitted to run this patch on server. Below are the steps to achive the requirement. 1/ Create a batch file which runs the IWUSERADM.exe.         echo - Add Teamsite User    CD E:\Appli\GN00\iw-home\bin    iwuseradm add-user %1 2/ Temporarily create a schedule task and run  the .bat file by scheduled task by ASP.Net code using TaskScheduler http://www.codeproject.com/KB/cs/tsnewlib.aspx. 3/ Here is the function: private int AddTeamsiteUser(string strBatchFilePath, string strUser) { //Get a ScheduledTasks object for the local computer. ScheduledTasks st = new ScheduledTasks(); // Create a task Task t; try{ t = st.CreateTask("~AddTeamsiteUser"); } catch { throw new Exception("Schedule Task ~AddTeamsiteUser already exist."); }    t.SetAccountInformation(yourLogin, yourPassword); //Set the account under which the task should run.  t.Save();  t.Run(); Thread.Sleep(2000); //for sync issue //Remove the scheduled task st.DeleteTask("~AddTeamsiteUser"); return t.ExitCode;   Below are few resources related to the above scenario:- - Task Scheduler Class Library for .NET  http://www.codeproject.com/KB/cs/tsnewlib.aspx - Run a .BAT file from ASP.NET  http://codebetter.com/blogs/brendan.tompkins/archive/2004/05/13/13484.aspx - TaskScheduler Class  http://msdn.microsoft.com/en-us/library/system.threading.tasks.taskscheduler.aspx - Application Hangs whle running iwuseradm.exe through ASP.Net  http://bytes.com/topic/asp-net/answers/733098-system-diagnostics-process-hangs     t.ApplicationName = strBatchFilePath; t.Parameters = strUser; t.Comment = "Adding user to Teamsite Application"

• Conflict between Change Control and ASL Mapping

  - by Jie Chen

  Yesterday I got one strange report that on Agile 9.3.1.2, adding a Supplier into Item's Supplier tab will always remove all the data from Item.PageTwo.MultiList01 field which is assigned to a User Group list. The detailed problem description is like below. In JavaClient, MultiList01 attribute on Parts class's PageTwo tab is enabled and assigned with User Group list. On WebClient, user created a new Part and assign MultiList01 with two UserGroups: "Global User Group Test1" and "Personal Group_Test1". Then go to Suppliers tab to add three Suppliers. Switch back to Part's TitleBlock, will see MultiList01 loses the User Group data. To confirm if MultiList01 really loses the data or it saves with other wrong data, I need to check the database and find strange data that MultiList01 saves wrong data ",7976911,7976907,7976959,", which are exactly the ID of these three Suppliers. Then I can suspect the Supplier attribute on Suppliers tab must be mapped to MultiList01. However when I check Supplier in JavaClient, the "ASL mapped to" is blank. More interesting thing is the database clearly shows Supplier attribute (Base ID =2000004219) is mapped to 2090, which is PageTwo.MultiList01 Base ID. Till now, we can get a conclusion that Supplier data is really mapped to MultiList01, though we assign MultiList01 to User Group list and Supplier does not set "ASL mapped to". It must be another function which overrides "ASL mapped to" visibility in JavaClient with high priority. That is the "Change Controlled" function. We immediately see "ASL mapped to" with value "MultiList01" when we disable Change Controlled for Multilist01 If one attribute is Change Controlled, Supplier data cannot be mapped to this attribute theoretically because Supplier could be dynamically modified by users, not by Changes. In real situation of Agile 9.3.1.2, it could be a Code Defect. We can imagine the scenario customer met. He setup Parts.PageTwo.Multilist01 assigned with Supplier list, then in Parts.Suppliers.Supplier attribute, he set "ASL mapped to" to "Multilist01". Later company business is changed, so he set Multilist01 with Change Controlled and re-assign with User Group list. He forgot to remove "ASL mapped to" before he did modifications to Multilist01. Finally we know the solution, it depends on real business. If still need to mapping Supplier to Parts.PageTwo attribute, should modify "ASL mapped to" to other one attribute which already has assigned with Suppliers list. If do not need "ASL mapped to" function, should delete the data from database level. We cannot do it from JavaClient UI. delete propertytable where id in (select p.id from propertytable p, nodetable n where p.parentid =n.id and n.inherit=2000004219 and propertyid=794)

• Why people don't patch and upgrade?!?

  - by Mike Dietrich

  Discussing the topic "Why Upgrade" or "Why not Upgrade" is not always fun. Actually the arguments repeat from customer to customer. Typically we hear things such as: A PSU or Patch Set introduces new bugs A new PSU or Patch Set introduces new features which lead to risk and require application verification  Patching means risk Patching changes the execution plans Patching requires too much testing Patching is too much work for our DBAs Patching costs a lot of money and doesn't pay out And to be very honest sometimes it's hard for me to stay calm in such discussions. Let's discuss some of these points a bit more in detail. A PSU or Patch Set introduces new bugsWell, yes, that is true as no software containing more than some lines of code is bug free. This applies to Oracle's code as well as too any application or operating system code. But first of all, does that mean you never patch your OS because the patch may introduce new flaws? And second, what is the point of saying "it introduces new bugs"? Does that mean you will never get rid of the mean issues we know about and we fixed already? Scroll down from MOS Note:161818.1 to the patch release you are on, no matter if it's 10.2.0.4 or 11.2.0.3 and check for the Known Issues And Alerts.Will you take responsibility to know about all these issues and refuse to upgrade to 11.2.0.4? I won't. A new PSU or Patch Set introduces new featuresOk, we can discuss that. Offering new functionality within a database patch set is a dubious thing. It has advantages such as in 11.2.0.4 where we backported Database Redaction to. But this is something you will only use once you have an Advanced Security license. I interpret that statement I've heard quite often from customers in a different way: People don't want to get surprises such as new behaviour. This certainly gives everybody a hard time. And we've had many examples in the past (SESSION_CACHED_CURSROS in 10.2.0.4,  _DATAFILE_WRITE_ERRORS_CRASH_INSTANCE in 11.2.0.2 and others) where those things weren't documented, not even in the README. Thanks to many friends out there I learned about those as well. So new behaviour is the topic people consider as risky - not really new features. And just to point this out: A PSU never brings in new features or new behaviour by definition! Patching means riskDoes it really mean risk? Yes, there were issues in the past (and sometimes in the present as well) where a patch didn't get installed correctly. But personally I consider it way more risky to not patch. Keep that in mind: The day Oracle publishes an PSU (or CPU) containing security fixes all the great security experts out there go public with their findings as well. So from that day on even my grandma can find out about those issues and try to attack somebody. Now a lot of people say: "My database does not face the internet." And I will answer: "The enemy is sitting already behind your firewalls. And knows potentially about these things." My statement: Not patching introduces way more risk to your environment than patching. Seriously! Patching changes the execution plansDo they really? I agree - there's a very small risk for this happening with Patch Sets. But not with PSUs or CPUs as they contain no optimizer fixes changing behaviour (but they may contain fixes curing wrong-query-result-bugs). But what's the point of a changing execution plan? In Oracle Database 11g it is so simple to be prepared. SQL Plan Management is a free EE feature - so once that occurs you'll put the plan into the Plan Baseline. Basta! Yes, you wouldn't like to get such surprises? Than please use the SQL Performance Analyzer (SPA) from Real Application Testing and you'll detect that easily upfront in minutes. And not to forget this, a plan change can also be very positive!Yes, there's a little risk with a database patchset - and we have many possibilites to detect this before patching. Patching requires too much testingWell, does it really? I have seen in the past 12 years how people test. There are very different efforts and approaches on this. I have seen people spending a hell of money on licenses or on project team staffing. And I have seen people sailing blindly without any tests just going the John-Wayne-approach.Proper tools will allow you to test easily without too much efforts. See the paragraph above. We have used Real Application Testing in so many customer projects reducing the amount of work spend on testing by over 50%. But apart from that at some point you will have to stop testing. If you don't you'll get lost and you'll burn money. There's no 100% guaranty. You will have to deal with a little risk as reaching the final 5% of certainty will cost you the same as it did cost to reach 95%. And doing this will lead to abnormal long product cycles that you'll run behind forever. And this will cost even more money. Patching is too much work for our DBAsPatching is a lot of work. I agree. And it's no fun work. It's boring, annoying. You don't learn much from that. That's why you should try to automate this task. Use the Database's Lifecycle Management Pack. And don't cry about the fact that it costs money. Yes it does. But it will ease the process and you'll save a lot of costs as you don't waste your valuable time with patching. Or use Oracle Database 12c Oracle Multitenant and patch either by unplug/plug or patch an entire container database with all PDBs with one patch in one task. We have customer reference cases proofing it saved them 75% of time, effort and cost since they've used Lifecycle Management Pack. So why don't you use it? Patching costs a lot of money and doesn't pay outWell, see my statements in the paragraph above. And it pays out as flying with a database with 100 known critical flaws in it which are already fixed by Oracle (such as in the Oct 2013 PSU for Oracle Database 12c) will cost ways more in case of failure or even data loss. Bet with me? Let me finally ask you some questions. What cell phone are you using and which OS does it run? Do you have an iPhone 5 and did you upgrade already to iOS 7.0.3? I've just encountered on mine that the alarm (which I rely on when traveling) has gotten now a dependency on the physical switch "sound on/off". If it is switched to "off" physically the alarm rings "silently". What a wonderful example of a behaviour change coming in with a patch set. Will this push you to stay with iOS5 or iOS6? No, because those have security flaws which won't be fixed anymore. What browser are you surfing with? Do you use Mozilla 3.6? Well, congratulations to all the hackers. It will be easy for them to attack you and harm your system. I'd guess you have the auto updater on.  Same for Google Chrome, Safari, IE.

• BI Applications overview

  - by sv744

  Welcome to Oracle BI applications blog! This blog will talk about various features, general roadmap, description of functionality and implementation steps related to Oracle BI applications. In the first post we start with an overview of the BI apps and will delve deeper into some of the topics below in the upcoming weeks and months. If there are other topics you would like us to talk about, pl feel free to provide feedback on that. The Oracle BI applications are a set of pre-built applications that enable pervasive BI by providing role-based insight for each functional area, including sales, service, marketing, contact center, finance, supplier/supply chain, HR/workforce, and executive management. For example, Sales Analytics includes role-based applications for sales executives, sales management, as well as front-line sales reps, each of whom have different needs. The applications integrate and transform data from a range of enterprise sources—including Siebel, Oracle, PeopleSoft, SAP, and others—into actionable intelligence for each business function and user role. This blog  starts with the key benefits and characteristics of Oracle BI applications. In a series of subsequent blogs, each of these points will be explained in detail. Why BI apps? Demonstrate the value of BI to a business user, show reports / dashboards / model that can answer their business questions as part of the sales cycle. Demonstrate technical feasibility of BI project and significantly lower risk and improve success Build Vs Buy benefit Don’t have to start with a blank sheet of paper. Help consolidate disparate systems Data integration in M&A situations Insulate BI consumers from changes in the OLTP Present OLTP data and highlight issues of poor data / missing data – and improve data quality and accuracy Prebuilt Integrations BI apps support prebuilt integrations against leading ERP sources: Fusion Applications, E- Business Suite, Peoplesoft, JD Edwards, Siebel, SAP Co-developed with inputs from functional experts in BI and Applications teams. Out of the box dimensional model to source model mappings Multi source and Multi Instance support Rich Data Model    BI apps have a very rich dimensionsal data model built over 10 years that incorporates best practises from BI modeling perspective as well as reflect the source system complexities  Thanks for reading a long post, and be on the lookout for future posts.  We will look forward to your valuable feedback on these topics as well as suggestions on what other topics would you like us to cover. I Conformed dimensional model across all business subject areas allows cross functional reporting, e.g. customer / supplier 360 Over 360 fact tables across 7 product areas CRM – 145, SCM – 47, Financials – 28, Procurement – 20, HCM – 27, Projects – 18, Campus Solutions – 21, PLM - 56 Supported by 300 physical dimensions Support for extensive calendars; Gregorian, enterprise and ledger based Conformed data model and metrics for real time vs warehouse based reporting  Multi-tenant enabled Extensive BI related transformations BI apps ETL and data integration support various transformations required for dimensional models and reporting requirements. All these have been distilled into common patterns and abstracted logic which can be readily reused across different modules Slowly Changing Dimension support Hierarchy flattening support Row / Column Hybrid Hierarchy Flattening As Is vs. As Was hierarchy support Currency Conversion :-  Support for 3 corporate, CRM, ledger and transaction currencies UOM conversion Internationalization / Localization Dynamic Data translations Code standardization (Domains) Historical Snapshots Cycle and process lifecycle computations Balance Facts Equalization of GL accounting chartfields/segments Standardized values for categorizing GL accounts Reconciliation between GL and subledgers to track accounted/transferred/posted transactions to GL Materialization of data only available through costly and complex APIs e.g. Fusion Payroll, EBS / Fusion Accruals Complex event Interpretation of source data – E.g. o    What constitutes a transfer o    Deriving supervisors via position hierarchy o    Deriving primary assignment in PSFT o    Categorizing and transposition to measures of Payroll Balances to specific metrics to support side by side comparison of measures of for example Fixed Salary, Variable Salary, Tax, Bonus, Overtime Payments. o    Counting of Events – E.g. converting events to fact counters so that for example the number of hires can easily be added up and compared alongside the total transfers and terminations. Multi pass processing of multiple sources e.g. headcount, salary, promotion, performance to allow side to side comparison. Adding value to data to aid analysis through banding, additional domain classifications and groupings to allow higher level analytical reporting and data discovery Calculation of complex measures examples: o    COGs, DSO, DPO, Inventory turns  etc o    Transfers within a Hierarchy or out of / into a hierarchy relative to view point in hierarchy. Configurability and Extensibility support  BI apps offer support for extensibility for various entities as automated extensibility or part of extension methodology Key Flex fields and Descriptive Flex support  Extensible attribute support (JDE)  Conformed Domains ETL Architecture BI apps offer a modular adapter architecture which allows support of multiple product lines into a single conformed model Multi Source Multi Technology Orchestration – creates load plan taking into account task dependencies and customers deployment to generate a plan based on a customers of multiple complex etl tasks Plan optimization allowing parallel ETL tasks Oracle: Bit map indexes and partition management High availability support    Follow the sun support. TCO BI apps support several utilities / capabilities that help with overall total cost of ownership and ensure a rapid implementation Improved cost of ownership – lower cost to deploy On-going support for new versions of the source application Task based setups flows Data Lineage Functional setup performed in Web UI by Functional person Configuration Test to Production support Security BI apps support both data and object security enabling implementations to quickly configure the application as per the reporting security needs Fine grain object security at report / dashboard and presentation catalog level Data Security integration with source systems  Extensible to support external data security rules Extensive Set of KPIs Over 7000 base and derived metrics across all modules Time series calculations (YoY, % growth etc) Common Currency and UOM reporting Cross subject area KPIs (analyzing HR vs GL data, drill from GL to AP/AR, etc) Prebuilt reports and dashboards 3000+ prebuilt reports supporting a large number of industries Hundreds of role based dashboards Dynamic currency conversion at dashboard level Highly tuned Performance The BI apps have been tuned over the years for both a very performant ETL and dashboard performance. The applications use best practises and advanced database features to enable the best possible performance. Optimized data model for BI and analytic queries Prebuilt aggregates& the ability for customers to create their own aggregates easily on warehouse facts allows for scalable end user performance Incremental extracts and loads Incremental Aggregate build Automatic table index and statistics management Parallel ETL loads Source system deletes handling Low latency extract with Golden Gate Micro ETL support Bitmap Indexes Partitioning support Modularized deployment, start small and add other subject areas seamlessly Source Specfic Staging and Real Time Schema Support for source specific operational reporting schema for EBS, PSFT, Siebel and JDE Application Integrations The BI apps also allow for integration with source systems as well as other applications that provide value add through BI and enable BI consumption during operational decision making Embedded dashboards for Fusion, EBS and Siebel applications Action Link support Marketing Segmentation Sales Predictor Dashboard Territory Management External Integrations The BI apps data integration choices include support for loading extenral data External data enrichment choices : UNSPSC, Item class etc. Extensible Spend Classification Broad Deployment Choices Exalytics support Databases :  Oracle, Exadata, Teradata, DB2, MSSQL ETL tool of choice : ODI (coming), Informatica Extensible and Customizable Extensible architecture and Methodology to add custom and external content Upgradable across releases

• A starting point for Use Cases and User Stories

  - by Mike Benkovich

  Originally posted on: http://geekswithblogs.net/benko/archive/2013/07/23/a-starting-point-for-use-cases-and-user-stories.aspxSoftware is a challenging business and is rife with opportunities to go wrong. Over the years a number of methodologies have evolved to help make sure that things go right. In an effort to contribute to this I’ve created a list of user stories that I think should be included and sometimes are just assumed. Note this is a work in progress, so I’m looking for your feedback. I’m curious what you would add or change in my list. · As a DBA I am working with a Normalized data model that reflects an agreed upon logical model for the system · As a DBA I am using consistent names for my fields which match the naming standards of my organization · As a DBA my model supports simple CRUD operations against all the entities · As an Application Architect the UI has been validated against the Business requirements and a complete set of user story’s have been created · As an Application Architect the database model has been validated against the UI · As an Application Architect we have a logical business model that describes all the known and/or expected usage of the system during the software’s expected lifecycle · As an Application Architect we have a Deployment diagram that describes how the application components will be deployed · As an Application Architect we have a navigation diagram that describes the typical application flow · As an Application Architect we have identified points of interaction which describes how the UI interacts with the services and the data storage · As an Application Architect we have identified external systems which may now or in the future use the data of this application and have adapted the logical model to include these interactions · As an Application Architect we have identified existing systems and tools that can be extended and/or reused to help this application achieve it’s business goals · As a Project Manager all team members understand the goals of each release and iteration as they are planned · As a Project Manager all team members understand their role and the roles of others · As a Project Manager we have support of the business to do the right thing even if it is not the expedient thing · As a Test/QA Analyst we have created a simulation environment for testing the system which does not use sensitive data and accurately reflects the scenarios of all the data that will be supported by the system · As a Test/QA Analyst we have identified the matrix of supported clients used to access the system including the likely browsers, mobile devices and other interfaces to work with the application · As a Test/QA Analyst we have created exit criteria for each user story that match the requirements of the business story that was used to create them · As a Test/QA Analyst we have access to a Test environment that is isolated from production and staging environments · As a Test/QA Analyst there we have a way to reset the environment so we can rerun tests when a new version of the software becomes available · As a Test/QA Analyst I am able to automate portions of the test process Thoughts? -mike
