• How to detect and configure an output with xrandr?

  - by ysap

  I have a DELL U2410 monitor connected to a Compaq 100B desktop equipped with an integrated AMD/ATI graphics card (AMD E-350). The installed O/S is Ubuntu 10.04 LTS. The computer is connected to the monitor via the DVI connection. The problem is that I cannot set the desktop resolution to the native 1920x1200. The maximum allowed resolution is 1600x1200. Doing some research I found about the xrandr utility. Unfortunately, when trying to use it I cannot configure it to the required resolution. First, it does not report the output name (which supposed to be DVI-0), saying default instead. Without it I cannot use the --fb option. The EDID utility seems to identify the monitor well. Here's the output from get-edid: # EDID version 1 revision 3 Section "Monitor" # Block type: 2:0 3:ff # Block type: 2:0 3:fc Identifier "DELL U2410" VendorName "DEL" ModelName "DELL U2410" # Block type: 2:0 3:ff # Block type: 2:0 3:fc # Block type: 2:0 3:fd HorizSync 30-81 VertRefresh 56-76 # Max dot clock (video bandwidth) 170 MHz # DPMS capabilities: Active off:yes Suspend:yes Standby:yes Mode "1920x1200" # vfreq 59.950Hz, hfreq 74.038kHz DotClock 154.000000 HTimings 1920 1968 2000 2080 VTimings 1200 1203 1209 1235 Flags "-HSync" "+VSync" EndMode # Block type: 2:0 3:ff # Block type: 2:0 3:fc # Block type: 2:0 3:fd EndSection but the xrandr -q command returns: Screen 0: minimum 640 x 400, current 1600 x 1200, maximum 1600 x 1200 default connected 1600x1200+0+0 0mm x 0mm 1600x1200 0.0* 1280x1024 0.0 1152x864 0.0 1024x768 0.0 800x600 0.0 640x480 0.0 720x400 0.0 When I try to set the resolution, I get: $ xrandr --fb 1920x1200 xrandr: screen cannot be larger than 1600x1200 (desired size 1920x1200) $ xrandr --output DVI-0 --auto warning: output DVI-0 not found; ignoring How can I set the screen resolution to 1920x1200? Why doesn't xrandr identify the DVI-0 output? Note that the same computer running Ubuntu version higher than 10.04 detects the correct resolution with no problems. On this machine I cannot upgrade due to some legacy hardware compatibility problems. Also, I don't see any optional screen drivers available in the Hardware Drivers dialog. ---- UPDATE: following the answer to this question, I got some advance. Now the required mode is listed in the xrandr -q list, but I can't switch to that mode. Using the Monitors applet (which now shows the new mode), I get the response that: The selected configuration for displays could not be applied. Could not set the configuration to CRTC 262.

• RPi and Java Embedded GPIO: Writing Java code to blink LED

  - by hinkmond

  So, you've followed the previous steps to install Java Embedded on your Raspberry Pi ?, you went to Fry's and picked up some jumper wires, LEDs, and resistors ?, you hooked up the wires, LED, and resistor the the correct pins ?, and now you want to start programming in Java on your RPi? Yes? ???????! OK, then... Here we go. You can use the following source code to blink your first LED on your RPi using Java. In the code you can see that I'm not using any complicated gpio libraries like wiringpi or pi4j, and I'm not doing any low-level pin manipulation like you can in C. And, I'm not using python (hell no!). This is Java programming, so we keep it simple (and more readable) than those other programming languages. See: Write Java code to do this In the Java code, I'm opening up the RPi Debian Wheezy well-defined file handles to control the GPIO ports. First I'm resetting everything using the unexport/export file handles. (On the RPi, if you open the well-defined file handles and write certain ASCII text to them, you can drive your GPIO to perform certain operations. See this GPIO reference). Next, I write a "1" then "0" to the value file handle of the GPIO0 port (see the previous pinout diagram). That makes the LED blink. Then, I loop to infinity. Easy, huh? import java.io.* /* * Java Embedded Raspberry Pi GPIO app */ package jerpigpio; import java.io.FileWriter; /** * * @author hinkmond */ public class JerpiGPIO { static final String GPIO_OUT = "out"; static final String GPIO_ON = "1"; static final String GPIO_OFF = "0"; static final String GPIO_CH00="0"; /** * @param args the command line arguments */ public static void main(String[] args) { FileWriter commandFile; try { /*** Init GPIO port for output ***/ // Open file handles to GPIO port unexport and export controls FileWriter unexportFile = new FileWriter("/sys/class/gpio/unexport"); FileWriter exportFile = new FileWriter("/sys/class/gpio/export"); // Reset the port unexportFile.write(GPIO_CH00); unexportFile.flush(); // Set the port for use exportFile.write(GPIO_CH00); exportFile.flush(); // Open file handle to port input/output control FileWriter directionFile = new FileWriter("/sys/class/gpio/gpio"+GPIO_CH00+"/direction"); // Set port for output directionFile.write(GPIO_OUT); directionFile.flush(); /*--- Send commands to GPIO port ---*/ // Opne file handle to issue commands to GPIO port commandFile = new FileWriter("/sys/class/gpio/gpio"+GPIO_CH00+"/value"); // Loop forever while (true) { // Set GPIO port ON commandFile.write(GPIO_ON); commandFile.flush(); // Wait for a while java.lang.Thread.sleep(200); // Set GPIO port OFF commandFile.write(GPIO_OFF); commandFile.flush(); // Wait for a while java.lang.Thread.sleep(200); } } catch (Exception exception) { exception.printStackTrace(); } } } Hinkmond

• How do I deal with a third party application that has embedded hints that result in a sub-optimal execution plan in my environment?

  - by Maria Colgan

  I have gotten many variations on this question recently as folks begin to upgrade to Oracle Database 11g and there have been several posts on this blog and on others describing how to use SQL Plan Management (SPM) so that a non-hinted SQL statement can use a plan generated with hints. But what if the hint is supplied in the third party application and is causing performance regressions on your system? You can actually use a very similar technique to the ones shown before but this time capture the un-hinted plan and have the hinted SQL statement use that plan instead. Below is an example that demonstrates the necessary steps. 1. We will begin by running the hinted statement 2. After examining the execution plan we can see it is suboptimal because of a bad join order. 3. In order to use SPM to correct the problem we must create a SQL plan baseline for the statement. In order to create a baseline we will need the SQL_ID for the hinted statement. Easy place to get it is in V$SQL. 4. A SQL plan baseline can be created using a SQL_ID and DBMS_SPM.LOAD_PLANS_FROM_CURSOR_CACHE. This will capture the existing plan for this SQL_ID from the shared pool and store in the SQL plan baseline. 5. We can check the SQL plan baseline got created successfully by querying DBA_SQL_PLAN_BASELINES. 6. When you manually create a SQL plan baseline the first plan added is automatically accepted and enabled. We know that the hinted plan is poorly performing plan so we will disable it using DBMS_SPM.ALTER_SQL_PLAN_BASELINE. Disabling the plan tells the optimizer that this plan not a good plan, however since there is no alternative plan at this point the optimizer will still continue to use this plan until we provide a better one. 7. Now let's run the statement without the hint. 8. Looking at the execution plan we can see that the join order is different. The plan without the hint also has a lower cost (3X lower), which indicates it should perform better. 9. In order to map the un-hinted plan to the hinted SQL statement we need to add the plan to the SQL plan baseline for the hinted statement. We can do this using DBMS_SPM.LOAD_PLANS_FROM_CURSOR_CACHE but we will need the SQL_ID and  PLAN_HASH_VALUE for the non-hinted statement, which we can find in V$SQL. 10. Now we can add the non-hinted plan to the SQL plan baseline of the hinted SQL statement using DBMS_SPM.LOAD_PLANS_FROM_CURSOR_CACHE. This time we need to pass a few more arguments. We will use the SQL_ID and PLAN_HASH_VALUE of the non-hinted statement but the SQL_HANDLE of the hinted statement. 11. The SQL plan baseline for our statement now has two plans. But only the newly added plan (SQL_PLAN_gbpcg3f67pc788a6d8911) is enabled and accepted. This tells the Optimizer that this is the plan it should use for this statement. We can confirm that the correct plan (non-hinted) will be selected for the statement from now on by re-executing the hinted statement and checking its execution plan.

• Direct3D11 and SharpDX - How to pass a model instance's world matrix as an input to a vertex shader

  - by Nathan Ridley

  Using Direct3D11, I'm trying to pass a matrix into my vertex shader from the instance buffer that is associated with a given model's vertices and I can't seem to construct my InputLayout without throwing an exception. The shader looks like this: cbuffer ConstantBuffer : register(b0) { matrix World; matrix View; matrix Projection; } struct VIn { float4 position: POSITION; matrix instance: INSTANCE; float4 color: COLOR; }; struct VOut { float4 position : SV_POSITION; float4 color : COLOR; }; VOut VShader(VIn input) { VOut output; output.position = mul(input.position, input.instance); output.position = mul(output.position, View); output.position = mul(output.position, Projection); output.color = input.color; return output; } The input layout looks like this: var elements = new[] { new InputElement("POSITION", 0, Format.R32G32B32_Float, 0, 0, InputClassification.PerVertexData, 0), new InputElement("INSTANCE", 0, Format.R32G32B32A32_Float, 0, 0, InputClassification.PerInstanceData, 1), new InputElement("COLOR", 0, Format.R32G32B32A32_Float, 12, 0) }; InputLayout = new InputLayout(device, signature, elements); The buffer initialization looks like this: public ModelDeviceData(Model model, Device device) { Model = model; var vertices = Helpers.CreateBuffer(device, BindFlags.VertexBuffer, model.Vertices); var instances = Helpers.CreateBuffer(device, BindFlags.VertexBuffer, Model.Instances.Select(m => m.WorldMatrix).ToArray()); VerticesBufferBinding = new VertexBufferBinding(vertices, Utilities.SizeOf<ColoredVertex>(), 0); InstancesBufferBinding = new VertexBufferBinding(instances, Utilities.SizeOf<Matrix>(), 0); IndicesBuffer = Helpers.CreateBuffer(device, BindFlags.IndexBuffer, model.Triangles); } The buffer creation helper method looks like this: public static Buffer CreateBuffer<T>(Device device, BindFlags bindFlags, params T[] items) where T : struct { var len = Utilities.SizeOf(items); var stream = new DataStream(len, true, true); foreach (var item in items) stream.Write(item); stream.Position = 0; var buffer = new Buffer(device, stream, len, ResourceUsage.Default, bindFlags, CpuAccessFlags.None, ResourceOptionFlags.None, 0); return buffer; } The line that instantiates the InputLayout object throws this exception: *HRESULT: [0x80070057], Module: [General], ApiCode: [E_INVALIDARG/Invalid Arguments], Message: The parameter is incorrect.* Note that the data for each model instance is simply an instance of SharpDX.Matrix. EDIT Based on Tordin's answer, it sems like I have to modify my code like so: var elements = new[] { new InputElement("POSITION", 0, Format.R32G32B32_Float, 0, 0, InputClassification.PerVertexData, 0), new InputElement("INSTANCE0", 0, Format.R32G32B32A32_Float, 0, 0, InputClassification.PerInstanceData, 1), new InputElement("INSTANCE1", 1, Format.R32G32B32A32_Float, 0, 0, InputClassification.PerInstanceData, 1), new InputElement("INSTANCE2", 2, Format.R32G32B32A32_Float, 0, 0, InputClassification.PerInstanceData, 1), new InputElement("INSTANCE3", 3, Format.R32G32B32A32_Float, 0, 0, InputClassification.PerInstanceData, 1), new InputElement("COLOR", 0, Format.R32G32B32A32_Float, 12, 0) }; and in the shader: struct VIn { float4 position: POSITION; float4 instance0: INSTANCE0; float4 instance1: INSTANCE1; float4 instance2: INSTANCE2; float4 instance3: INSTANCE3; float4 color: COLOR; }; VOut VShader(VIn input) { VOut output; matrix world = { input.instance0, input.instance1, input.instance2, input.instance3 }; output.position = mul(input.position, world); output.position = mul(output.position, View); output.position = mul(output.position, Projection); output.color = input.color; return output; } However I still get an exception.

• Using 3G/UMTS in Mauritius

  After some conversation, threads in online forum and mailing lists I thought about writing this article on how to setup, configure and use 3G/UMTS connections on Linux here in Mauritius. Personally, I can only share my experience with Emtel Ltd. but try to give some clues about how to configure Orange as well. Emtel 3G/UMTS surf stick Emtel provides different surf sticks from Huawei. Back in 2007, I started with an E220 that wouldn't run on Windows Vista either. Nowadays, you just plug in the surf stick (ie. E169) and usually the Network Manager will detect the new broadband modem. Nothing to worry about. The Linux Network Manager even provides a connection profile for Emtel here in Mauritius and establishing the Internet connection is done in less than 2 minutes... even quicker. Using wvdial Old-fashioned Linux users might not take Network Manager into consideration but feel comfortable with wvdial. Although that wvdial is primarily used with serial port attached modems, it can operate on USB ports as well. Following is my configuration from /etc/wvdial.conf: [Dialer Defaults]Phone = *99#Username = emtelPassword = emtelNew PPPD = yesStupid Mode = 1Dial Command = ATDT[Dialer emtel]Modem = /dev/ttyUSB0Baud = 3774000Init2 = ATZInit3 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0Init4 = AT+cgdcont=1,"ip","web"ISDN = 0Modem Type = Analog Modem The values of user name and password are optional and can be configured as you like. In case that your SIM card is protected by a pin - which is highly advised, you might another dialer section in your configuration file like so: [Dialer pin]Modem = /dev/ttyUSB0Init1 = AT+CPIN=0000 This way you can "daisy-chain" your command to establish your Internet connection like so: wvdial pin emtel And it works auto-magically. Depending on your group assignments (dialout), you might have to sudo the wvdial statement like so: sudo wvdial pin emtel Orange parameters As far as I could figure out without really testing it myself, it is also necessary to set the Access Point (AP) manually with Orange. Well, although it is pretty obvious a lot of people seem to struggle. The AP value is "orange". [Dialer orange]Modem = /dev/ttyUSB0Baud = 3774000Init2 = ATZInit3 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0Init4 = AT+cgdcont=1,"ip","orange"ISDN = 0Modem Type = Analog Modem And you are done. Official Linux support from providers It's just simple: Forget it! The people at the Emtel call center are completely focused on the hardware and Mobile Connect software application provided by Huawei and are totally lost in case that you confront them with other constellations. For example, my wife's netbook has an integrated 3G/UMTS modem from Ericsson. Therefore, no need to use the Huawei surf stick at all and of course we use the existing software named Wireless Manager instead of. Now, imagine to mention at the help desk: "Ehm, sorry but what's Mobile Connect?" And Linux after all might give the call operator sleepless nights... Who knows? Anyways, I hope that my article and configuration could give you a helping hand and that you will be able to connect your Linux box with 3G/UMTS surf sticks here in Mauritius.

• Copy TFS Build Definitions between Projects and Collections

  - by Jakob Ehn

  Originally posted on: http://geekswithblogs.net/jakob/archive/2014/06/05/copy-tfs-build-definitions-between-projects-and-collections.aspxThe last couple of years it has become apparent that using multiple team projects in TFS is generally a bad idea. There are of course exceptions to this, but there are a lot ot things that becomes much easier to do when you put all of your projects and team in the same team project. Fellow ALM MVP Martin Hinshelwood has blogged about this several times, as well as other people in the community. In particular, using the backlog and portfolio management tools makes much more sense when everything is located in the same team project. Consolidating multiple team projects into one is not that easy unfortunately, it involves migrating source code, work items, reports etc.  Another thing that also need to be migrated is build definitions. It is possible to clone build definitions within the same team project using the TFS power tools. The Community TFS Build Manager also lets you clone build definitions to other team projects. But there is no tool that allows you to clone/copy a build definition to another collection. So, I whipped up a simple console application that let you do this. The tool can be downloaded from https://onedrive.live.com/redir?resid=EE034C9F620CD58D!8162&authkey=!ACTr56v1QVowzuE&ithint=file%2c.zip   Using CopyTFSBuildDefinitions You use the tool like this: CopyTFSBuildDefinitions  SourceCollectionUrl  SourceTeamProject  BuildDefinitionName  DestinationCollectionUrl  DestinationTeamProject [NewDefinitionName] Arguments SourceCollectionUrl The URL to the TFS collection that contains the team project with the build definition that you want to copy SourceTeamProject The name of the team project that contains the build definition BuildDefinitionName Name of the build definition DestinationCollectionUrl The URL to the TFS collection that contains the team project that you want to copy your build definition to DestinationTeamProject The name of the team project in the destination collection NewDefinitionName (Optional) Use this to override the name of the new build definition. If you don’t specify this, the name will the same as the original one Example: CopyTFSBuildDefinitions  https://jakob.visualstudio.com DemoProject  WebApplication.CI https://anotheraccount.visualstudio.com     Notes Since we are (potentially) create a build definition in a new collection, there is no guarantee that the various paths that are defined in the build definition exist in the new collection. For example, a build definition refers to server paths in TFVC or repos + branches in TFGit. It also refers to build controllers that definitely don’t exist in the new collection. So there will be some cleanup to do after you copy your build definitions. You can fix some of these using the Community TFS Build Manager, for example it is very easy to apply the correct build controller to a set of build definitions The problem stated above also applies to build process templates. However, the tool tries to find a build process template in the new team project with the same file name as the one that existed in the old team project. If it finds one, it will be used for the new build definition. Otherwise is will use the default build template If you want to run the tool for many build definitions, you can use this SQL scripts, compliments of Mr. Scrum/ALM MVP Richard Hundhausen to generate the necessary commands: USE Tfs_Collection GO SELECT 'CopyTFSBuildDefinitions.exe http://SERVER:8080/tfs/collection "' + P.ProjectName + '" "' + REPLACE(BD.DefinitionName,'\','') + '" http://NEWSERVER:8080/tfs/COLLECTION TEAMPROJECT'   FROM tbl_Project P        INNER JOIN tbl_BuildGroup BG on BG.TeamProject = P.ProjectUri        INNER JOIN tbl_BuildDefinition BD on BD.GroupId = BG.GroupId   ORDER BY P.ProjectName, BD.DefinitionName   Hope that helps, let me know if you have any problems with the tool or if you find it useful

• HSSFS Part 2.1 - Parsing @@VERSION

  - by Most Valuable Yak (Rob Volk)

  For Part 2 of the Handy SQL Server Function Series I decided to tackle parsing useful information from the @@VERSION function, because I am an idiot.  It turns out I was confused about CHARINDEX() vs. PATINDEX() and it pretty much invalidated my original solution.  All is not lost though, this mistake turned out to be informative for me, and hopefully for you. Referring back to the "Version" view in the prelude I started with the following query to extract the version number: SELECT DISTINCT SQLVersion, SUBSTRING(VersionString,PATINDEX('%-%',VersionString)+2, 12) VerNum FROM VERSION I used PATINDEX() to find the first hyphen "-" character in the string, since the version number appears 2 positions after it, and got these results: SQLVersion VerNum ----------- ------------ 2000 8.00.2055 (I 2005 9.00.3080.00 2005 9.00.4053.00 2008 10.50.1600.1 As you can see it was good enough for most of the values, but not for the SQL 2000 @@VERSION.  You'll notice it has only 3 version sections/octets where the others have 4, and the SUBSTRING() grabbed the non-numeric characters after.  To properly parse the version number will require a non-fixed value for the 3rd parameter of SUBSTRING(), which is the number of characters to extract. The best value is the position of the first space to occur after the version number (VN), the trick is to figure out how to find it.  Here's where my confusion about PATINDEX() came about.  The CHARINDEX() function has a handy optional 3rd parameter: CHARINDEX (expression1 ,expression2 [ ,start_location ] ) While PATINDEX(): PATINDEX ('%pattern%',expression ) Does not.  I had expected to use PATINDEX() to start searching for a space AFTER the position of the VN, but it doesn't work that way.  Since there are plenty of spaces before the VN, I thought I'd try PATINDEX() on another character that doesn't appear before, and tried "(": SELECT SQLVersion, SUBSTRING(VersionString,PATINDEX('%-%',VersionString)+2, PATINDEX('%(%',VersionString)) FROM VERSION Unfortunately this messes up the length calculation and yields: SQLVersion VerNum ----------- --------------------------- 2000 8.00.2055 (Intel X86) Dec 16 2008 19:4 2005 9.00.3080.00 (Intel X86) Sep 6 2009 01: 2005 9.00.4053.00 (Intel X86) May 26 2009 14: 2008 10.50.1600.1 (Intel X86) Apr 2008 10.50.1600.1 (X64) Apr 2 20 Yuck.  The problem is that PATINDEX() returns position, and SUBSTRING() needs length, so I have to subtract the VN starting position: SELECT SQLVersion, SUBSTRING(VersionString,PATINDEX('%-%',VersionString)+2, PATINDEX('%(%',VersionString)-PATINDEX('%-%',VersionString)) VerNum FROM VERSION And the results are: SQLVersion VerNum ----------- -------------------------------------------------------- 2000 8.00.2055 (I 2005 9.00.4053.00 (I Msg 537, Level 16, State 2, Line 1 Invalid length parameter passed to the LEFT or SUBSTRING function. Ummmm, whoops.  Turns out SQL Server 2008 R2 includes "(RTM)" before the VN, and that causes the length to turn negative. So now that that blew up, I started to think about matching digit and dot (.) patterns.  Sadly, a quick look at the first set of results will quickly scuttle that idea, since different versions have different digit patterns and lengths. At this point (which took far longer than I wanted) I decided to cut my losses and redo the query using CHARINDEX(), which I'll cover in Part 2.2.  So to do a little post-mortem on this technique: PATINDEX() doesn't have the flexibility to match the digit pattern of the version number; PATINDEX() doesn't have a "start" parameter like CHARINDEX(), that allows us to skip over parts of the string; The SUBSTRING() expression is getting pretty complicated for this relatively simple task! This doesn't mean that PATINDEX() isn't useful, it's just not a good fit for this particular problem.  I'll include a version in the next post that extracts the version number properly. UPDATE: Sorry if you saw the unformatted version of this earlier, I'm on a quest to find blog software that ACTUALLY WORKS.

• JustMock is here !!

  - by mehfuzh

  As announced earlier by Hristo Kosev at Telerik blogs , we have started giving out JustMock builds from today. This is the first of early builds before the official Q2 release and we are pretty excited to get your feedbacks. Its pretty early to say anything on it. It actually depends on your feedback. To add few, with JustMock we tried to build a mocking tool with simple and intuitive syntax as possible excluding more and more noises and avoiding any smell that can be made to your code [We are still trying everyday] and we want to make the tool even better with your help. JustMock can be used to mock virtually anything. Moreover, we left an option open that it can be used to reduce / elevate the features  just though a single click. We tried to make a strong API and make stuffs fluent and guided as possible so that you never have the chance to get de-railed. Our syntax is AAA (Arrange – Act – Assert) , we don’t believe in Record – Reply model which some of the smarter mocking tools are planning to remove from their coming release or even don’t have [its always fun to lean from each other]. Overall more signals equals more complexity , reminds me of 37 signals :-). Currently, here are the things you can do with JustMock ( will cover more in-depth in coming days) Proxied mode Mock interfaces and class with virtuals Mock properties that includes indexers Set raise event for specific calls Use matchers to control mock arguments Assert specific occurrence of a mocked calls. Assert using matchers Do recursive mocks Do Sequential mocking ( same method with argument returns different values or perform different tasks) Do strict mocking (by default and i prefer loose , so that i can use it as stubs) Elevated mode Mock static calls Mock final class Mock sealed classes Mock Extension methods Partially mock a  class member directly using Mock.Arrange Mock MsCorlib (we will support more and more members in coming days) , currently we support FileInfo, File and DateTime. These are few, you need to take a look at the test project that is provided with the build to find more [Along with the document]. Also, one of feature that will i will be using it for my next OS projects is the ability to run it separately in  proxied mode which makes it easy to redistribute and do some personal development in a more DI model and my option to elevate as it go.   I’ve surely forgotten tons of other features to mention that i will cover time but  don’t for get the URL : www.telerik.com/justmock   Finally a little mock code:   var lvMock = Mock.Create<ILoveJustMock>();    // set your goal  Mock.Arrange(() => lvMock.Response(Arg.Any<string>())).Returns((int result) => result);    //perform  string ret =  lvMock.Echo("Yes");    Assert.Equal(ret, "Yes");  // make sure everything is fine  Mock.Assert(() => lvMock.Echo("Yes"), Occurs.Once());   Hope that helps to get started,  will cover if not :-).

• Chrome Web Browser Messages: Some Observations

  - by ultan o'broin

  I'm always on the lookout for how different apps handle errors and what kind of messages are shown (I probably need to get out more), I use this 'research' to reflect on our own application error messages patterns and guidelines and how we might make things better for our users in future. Users are influenced by all sorts of things, but their everyday experiences of technology, and especially what they encounter on the internet, increasingly sets their expectations for the enterprise user experience too. I recently came across a couple of examples from Google's Chrome web browser that got me thinking. In the first case, we have a Chrome error about not being able to find a web page. I like how simple, straightforward messaging language is used along with an optional ability to explore things a bit further--for those users who want to. The 'more information' option shows the error encountered by the browser (or 'original' error) in technical terms, along with an error number. Contrasting the two messages about essentially the same problem reveals what's useful to users and what's not. Everyone can use the first message, but the technical version of the message has to be explicitly disclosed for any more advanced user to pursue further. More technical users might search for a resolution, using that Error 324 number, but I imagine most users who see the message will try again later or check their URL again. Seems reasonable that such an approach be adopted in the enterprise space too, right? Maybe. Generally, end users don't go searching for solutions based on those error numbers, and help desk folks generally prefer they don't do so. That's because of the more critical nature of enterprise data or the fact that end users may not have the necessary privileges to make any fixes anyway. What might be more useful here is a link to a trusted source of additional help provided by the help desk or reputable community instead. This takes me on to the second case, this time more closely related to the language used in messaging situations. Here, I first noticed by the using of the (s) approach to convey possibilities of there being one or more pages at the heart of the problem. This approach is a no-no in Oracle style terms (the plural would be used) and it can create translation issues (though it is not a show-stopper). I think Google could have gone with the plural too. However, of more interest is the use of the verb "kill", shown in the message text and as an action button label. For many writers, words like "kill" and "abort" are to be avoided as they can give offense. I am not so sure about that judgment, as really their use cannot be separated from the context. Certainly, for more technical users, they're fine and have been in use for years, so I see no reason to avoid these terms if the audience has accepted them. Most end users too, I think would find the idea of "kill" usable and may even use the term in every day speech. Others might disagree--Apple uses a concept of Force Quit, for example. Ultimately, the only way to really know how to proceed is to research these matter by asking users of differing roles and expertise to perform some tasks, encounter these messages and then make recommendations based on those findings for our designs. Something to do in 2011!

• Stuck due to "knowing too much"

  - by Ran Biron

  Note more discussion at http://news.ycombinator.com/item?id=4037794 Welcome Hacker News Visitors! While HN is a fine forum for discussion and debate, Programmers - Stack Exchange is not. From the FAQ: If your motivation for asking the question is “I would like to participate in a discussion about ____”, then you should not be asking here. However, if your motivation is “I would like others to explain ____ to me”, then you are probably OK. (Discussions are of course welcome in our real time web chat.) Currently, this question is viewed by the membership of Programmers.SE as more likely to provoke unproductive discussion than constructive answers; while debates on its form and future are conducted, it will be locked to prevent arguments and vandalism. -- Shog9 I have a relatively simple development task, but every time I try to attack it, I end up spiraling in deep thoughts - how could it extending the future, what are the 2nd generation clients going to need, how does it affect "non functional" aspects (e.g. Performance, authorization...), how would it best be architectured to allow change... I remember myself a while ago, younger and, perhaps, more eager. The "me" I was then wouldn't have given a thought about all that - he would've gone ahead and wrote something, then rewrote it, then rewrote it again (and again...). The "me" today is more hesitant, more careful. I find it much easier today to sit and plan and instruct other people on how to do things than to actually go ahead and do them myself - not because I don't like to code - the opposite, I love to! - but because every time I sit at the keyboard, I end up in that same annoying place. Is this wrong? Is this a natural evolution, or did I drive myself into a rut? Fair disclosure - in the past I was a developer, today my job title is a "system architect". Good luck figuring what it means - but that's the title. Wow. I honestly didn't expect this question to generate that many responses. I'll try to sum it up. Reasons: Analysis paralysis / Over engineering / gold plating / (any other "too much thinking up-front can hurt you"). Too much experience for the given task. Not focusing on what's important. Not enough experience (and realizing that). Solutions (not matched to reasons): Testing first. Start coding (+ for fun) One to throw away (+ one API to throw away). Set time constraints. Strip away the fluff, stay with the stuff. Make flexible code (kinda opposite to "one to throw away", no?). Thanks to everyone - I think the major benefit here was to realize that I'm not alone in this experience. I have, actually, already started coding and some of the too-big things have fallen off, naturally. Since this question is closed, I'll accept the answer with most votes as of today. When/if it changes - I'll try to follow.

• Installing Eclipse for OSB Development

  - by James Taylor

  OSB provides 2 methods for OSB development, the OSB console, and Eclipse. This post deals with a typical development environment with OSB installed on a remote server and the developer requiring an IDE on their PC for development. As at 11.1.1.4 Eclipse is only IDE supported for OSB development. We are hoping OSB will support JDeveloper in the future. To get the download for Eclipse use the download WebLogic Server with the Oracle Enterprise Pack for Eclipse, e.g. wls1034_oepe111161_win32.exe.To ensure the Eclipse version is compatible with your OSB version I recommend using the Eclipse that comes with the supported WLS server, e.g. OSB 11.1.1.4 you would install WLS 10.3.4+oepe.The install is a 2 step process, install the base Eclipse, then install the OSB plugins. In this example I'm using the 11.1.1.4 install for windows, your versions may differ. You need to download 2 programs, WebLogic Server with the oepe plugin for your OS, and the Oracle Service Bus which is generally generic. Place these files in a directory of your choice. Start the executable I create a new Oracle Home for this installation as it don't want to impact on my JDeveloper install or any other Oracle products installed on my machine. Ignore the support / email notifications Choose a custom install as we only want to install the minimum for Eclipse. If you really want you can do a typical and install everything. Deselect all products then select the Oracle Enterprise Pack for Eclipse. This will select the minimum prerequisites required for install. As I'm only going to use this home for OSB Development I deselect the JRockit JVM. Accept the locations for the installs. If running on a Windows environment you will be asked to start a Node Manger service. This is optional. I have chosen to ignore. Select the user permissions you require, I have set to default. Do a last check to see if the values are correct and continue to install. The install should start. The install should complete successfully. I chose not to run the Quick Start. Extract the OSB download to a location of your choice and double click on the setup.exe. You may be asked to supply a correct java location. Point this to the java installed in your OS. I'm running Windows 7 so I used the 64bit version. Skip the software updates. Set the OSB home to the location of the WLS home installed above Choose a custom install as all we want to install is the OSB Eclipse Plugins. Select OSB IDE. For the rest of the install screens accept the defaults. Start the install There is no need to configure a WLS domain if you only intend to deploy to the remote server. If you need to do this there are other sites how to configure via the configuration wizard. Start Eclipse to make sure the OSB Plugin has been created. In the top right drop down you should see OSB as an option. Connecting to the remote server, select the Server Tab at the bottom Right-click in that frame and select Server. Chose the remote server version and the hostname Provide and name for your server if necessary, and accept the defaults Enter connection details for the remote server Click on the Remote server and it should validate stating its status.Now you ready to develop, Happy developing!

• Converting from mp4 to Xvid avi using avconv?

  - by Ricardo Gladwell

  I normally use avidemux to convert mp4s to Xvid AVI for my Philips Streamium SLM5500. Normally I select MPEG-4 ASP (Xvid) at Two Pass with an average bitrate f 1500kb/s for video and AC3 (lav) audio and it converts correctly. However, I'm trying to using avconv so I can automate the process with a script, but when I do this the video stutters and stops playing part way through. I have a suspicion its something to do with a faulty audio conversion. The commands I'm using are as follows: avconv -y -i video.mp4 -pass 1 -vtag xvid -c:a ac3 -b:a 128k -b:v 1500k -f avi /dev/null avconv -y -i video.mp4 -pass 2 -vtag xvid -c:a ac3 -b:a 128k -b:v 1500k -f avi video.avi There is a bewildering array of arguments for avconv. Is there something I'm doing wrong? Is there a way I can script avidemux from a headless server? Please see command line output: $ avconv -y -i video.mp4 -pass 1 -vtag xvid -an -b:v 1500k -f avi /dev/null avconv version 0.8.5-6:0.8.5-0ubuntu0.12.10.1, Copyright (c) 2000-2012 the Libav developers built on Jan 24 2013 14:49:20 with gcc 4.7.2 Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'video.mp4': Metadata: major_brand : isom minor_version : 1 compatible_brands: isomavc1 creation_time : 2013-02-04 13:53:38 Duration: 00:44:09.16, start: 0.000000, bitrate: 669 kb/s Stream #0.0(und): Video: h264 (High), yuv420p, 720x404 [PAR 1:1 DAR 180:101], 538 kb/s, 25 fps, 25 tbr, 100 tbn, 50 tbc Metadata: creation_time : 2013-02-04 13:53:38 Stream #0.1(und): Audio: ac3, 44100 Hz, stereo, s16, 127 kb/s Metadata: creation_time : 2013-02-04 13:53:42 [buffer @ 0x7f4c40] w:720 h:404 pixfmt:yuv420p Output #0, avi, to '/dev/null': Metadata: major_brand : isom minor_version : 1 compatible_brands: isomavc1 creation_time : 2013-02-04 13:53:38 ISFT : Lavf53.21.1 Stream #0.0(und): Video: mpeg4, yuv420p, 720x404 [PAR 1:1 DAR 180:101], q=2-31, pass 1, 1500 kb/s, 25 tbn, 25 tbc Metadata: creation_time : 2013-02-04 13:53:38 Stream mapping: Stream #0:0 -> #0:0 (h264 -> mpeg4) Press ctrl-c to stop encoding frame=66227 fps=328 q=2.0 Lsize= 0kB time=2649.16 bitrate= 0.0kbits/s video:401602kB audio:0kB global headers:0kB muxing overhead -100.000000% $ avconv -y -i video.mp4 -pass 2 -vtag xvid -c:a ac3 -b:a 128k -b:v 1500k -f avi video.avi avconv version 0.8.5-6:0.8.5-0ubuntu0.12.10.1, Copyright (c) 2000-2012 the Libav developers built on Jan 24 2013 14:49:20 with gcc 4.7.2 Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'video.mp4': Metadata: major_brand : isom minor_version : 1 compatible_brands: isomavc1 creation_time : 2013-02-04 13:53:38 Duration: 00:44:09.16, start: 0.000000, bitrate: 669 kb/s Stream #0.0(und): Video: h264 (High), yuv420p, 720x404 [PAR 1:1 DAR 180:101], 538 kb/s, 25 fps, 25 tbr, 100 tbn, 50 tbc Metadata: creation_time : 2013-02-04 13:53:38 Stream #0.1(und): Audio: ac3, 44100 Hz, stereo, s16, 127 kb/s Metadata: creation_time : 2013-02-04 13:53:42 [buffer @ 0x12b4f00] w:720 h:404 pixfmt:yuv420p Incompatible sample format 's16' for codec 'ac3', auto-selecting format 'flt' [mpeg4 @ 0x12b3ec0] [lavc rc] Using all of requested bitrate is not necessary for this video with these parameters.

• ATG Live Webcast June 28: Scrambling Sensitive Data in EBS 12 Cloned Environments

  - by BillSawyer

  Securing the Oracle E-Business Suite includes protecting the underlying E-Business data in production and non-production databases.  While steps can be taken to provide a secure configuration to limit EBS access, a better approach to protecting non-production data is simply to scramble (mask) the data in the non-production copy.   The Oracle E-Business Suite Template for Data Masking Pack can be used in situations where confidential or regulated data needs to be shared with other non-production users who need access to some of the original data, but not necessarily every table.  Examples of non-production users include internal application developers or external business partners such as offshore testing companies, suppliers or customers. The Oracle E-Business Suite Template for Data Masking Pack is applied to a non-production environment with the Enterprise Manager Grid Control Data Masking Pack.  When applied, the Oracle E-Business Suite Template for Data Masking Pack will create an irreversibly scrambled version of your production database for development and testing. This ATG Live Webcast is your chance to come learn about the Oracle E-Business Suite Release 12.1.3 Template for Data Masking Pack from the experts. Oracle E-Business Suite Release 12.1.3 Template for Data Masking The agenda for the Oracle E-Business Suite Template for Data Masking Pack webcast includes the following topics: What does data masking do in E-Business Suite environments? De-identify the data Mask sensitive data Maintain data validity How can EBS customers use data masking?

• F1 Pit Pragmatics

  - by mikef

  "I hate computers. No, really, I hate them. I love the communications they facilitate, I love the conveniences they provide to my life. but I actually hate the computers themselves." - Scott Merrill, 'I hate computers: confessions of a Sysadmin' If Scott's goal was to polarize opinion and trigger raging arguments over the 'real reasons why computers suck', then he certainly succeeded. Impassioned vitriol sits side-by-side with rational debate. Yet Scott's fundamental point is absolutely on the money - Computers are a means to an end. The IT industry is finally starting to put weight behind the notion that good User Experience is an absolutely crucial goal, a cause championed by the likes of Microsoft's Bill Buxton, and which Apple's increasingly ubiquitous touch screen interface exemplifies. However, that doesn't change the fact that, occasionally, you just have to man up and deal with complex systems. In fact, sometimes you just need to sacrifice everything else in the name of performance. You'll find a perfect example of this Faustian bargain in Trevor Clarke's fascinating look into the (diabolical) IT infrastructure of modern F1 racing - high performance, high availability. high everything. To paraphrase, each car has up to 100 sensors, transmitting around 30Gb of data over the course of a race (70% in real-time). This data is then processed by no less than 3 servers (per car) so that the engineers in the pit have access to telemetry, strategy information, timing feeds, a connection back to the operations room in the team's home base - the list goes on. All of this while the servers are exposed "to carbon dust, oil, vibration, rain, heat, [and] variable power". Now, this is admittedly an extreme context where there's no real choice but to use complex systems where ease-of-use is, at best, a secondary concern. The flip-side is seen in small-scale personal computing such as that seen in Apple's iDevices, which are incredibly intuitive but limited in their scope. In terms of what kinds of systems they prefer to use, I suspect that most SysAdmins find themselves somewhere along this axis of Power vs. Usability, and which end of this axis you resonate with also hints at where you think the IT industry should focus its energy. Do you see yourself in the F1 pit, making split-second decisions, wrestling with information flows and reticent hardware to bend them to your will? If so, I imagine you feel that computers are subtle tools which need to be tuned and honed, using the advanced knowledge possessed only by responsible SysAdmins (If you have an iPhone, I suspect it's jail-broken). If the machines throw enigmatic errors, it's the price of flexibility and raw power. Alternatively, would you prefer to have your role more accessible, with users empowered by knowledge, spreading the load of managing IT environments? In that case, then you want hardware and software to have User Experience as their primary focus, and are of the "means to an end" school of thought (you're probably also fed up with users not listening to you when you try and help). At its heart, the dichotomy is between raw power (which might be difficult to use) and ease-of-use (which might have some limitations, but you can be up and running immediately). Of course, the ultimate goal is a fusion of flexibility, power and usability all in one system. It's achievable in specific software environments, and Red Gate considers it a target worth aiming for, but in other cases it's a goal right up there with cold fusion. I think it'll be a long time before we see it become ubiquitous. In the meantime, are you Power-Hungry or a Champion of Usability? Cheers, Michael Francis Simple Talk SysAdmin Editor

• Do we still have a case against the goto statement? [closed]

  - by FredOverflow

  Possible Duplicate: Is it ever worthwhile using goto? In a recent article, Andrew Koenig writes: When asked why goto statements are harmful, most programmers will say something like "because they make programs hard to understand." Press harder, and you may well hear something like "I don't really know, but that's what I was taught." For that reason, I'd like to summarize Dijkstra's arguments. He then shows two program fragments, one without a goto and and one with a goto: if (n < 0) n = 0; Assuming that n is a variable of a built-in numeric type, we know that after this code, n is nonnegative. Suppose we rewrite this fragment: if (n >= 0) goto nonneg; n = 0; nonneg: ; In theory, this rewrite should have the same effect as the original. However, rewriting has changed something important: It has opened the possibility of transferring control to nonneg from anywhere else in the program. I emphasized the part that I don't agree with. Modern languages like C++ do not allow goto to transfer control arbitrarily. Here are two examples: You cannot jump to a label that is defined in a different function. You cannot jump over a variable initialization. Now consider composing your code of tiny functions that adhere to the single responsibility principle: int clamp_to_zero(int n) { if (n >= 0) goto n_is_not_negative: n = 0; n_is_not_negative: return n; } The classic argument against the goto statement is that control could have transferred from anywhere inside your program to the label n_is_not_negative, but this simply is not (and was never) true in C++. If you try it, you will get a compiler error, because labels are scoped. The rest of the program doesn't even see the name n_is_not_negative, so it's just not possible to jump there. This is a static guarantee! Now, I'm not saying that this version is better then the one without the goto, but to make the latter as expressive as the first one, we would at least have to insert a comment, or even better yet, an assertion: int clamp_to_zero(int n) { if (n < 0) n = 0; // n is not negative at this point assert(n >= 0); return n; } Note that you basically get the assertion for free in the goto version, because the condition n >= 0 is already written in line 1, and n = 0; satisfies the condition trivially. But that's just a random observation. It seems to me that "don't use gotos!" is one of those dogmas like "don't use multiple returns!" that stem from a time where the real problem were functions of hundreds or even thousand of lines of code. So, do we still have a case against the goto statement, other than that it is not particularly useful? I haven't written a goto in at least a decade, but it's not like I was running away in terror whenever I encountered one. 1 Ideally, I would like to see a strong and valid argument against gotos that still holds when you adhere to established programming principles for clean code like the SRP. "You can jump anywhere" is not (and has never been) a valid argument in C++, and somehow I don't like teaching stuff that is not true. 1: Also, I have never been able to resurrect even a single velociraptor, no matter how many gotos I tried :(

• Improvements to Joshua Bloch's Builder Design Pattern?

  - by Jason Fotinatos

  Back in 2007, I read an article about Joshua Blochs take on the "builder pattern" and how it could be modified to improve the overuse of constructors and setters, especially when an object has a large number of properties, most of which are optional. A brief summary of this design pattern is articled here [http://rwhansen.blogspot.com/2007/07/theres-builder-pattern-that-joshua.html]. I liked the idea, and have been using it since. The problem with it, while it is very clean and nice to use from the client perspective, implementing it can be a pain in the bum! There are so many different places in the object where a single property is reference, and thus creating the object, and adding a new property takes a lot of time. So...I had an idea. First, an example object in Joshua Bloch's style: Josh Bloch Style: public class OptionsJoshBlochStyle { private final String option1; private final int option2; // ...other options here <<<< public String getOption1() { return option1; } public int getOption2() { return option2; } public static class Builder { private String option1; private int option2; // other options here <<<<< public Builder option1(String option1) { this.option1 = option1; return this; } public Builder option2(int option2) { this.option2 = option2; return this; } public OptionsJoshBlochStyle build() { return new OptionsJoshBlochStyle(this); } } private OptionsJoshBlochStyle(Builder builder) { this.option1 = builder.option1; this.option2 = builder.option2; // other options here <<<<<< } public static void main(String[] args) { OptionsJoshBlochStyle optionsVariation1 = new OptionsJoshBlochStyle.Builder().option1("firefox").option2(1).build(); OptionsJoshBlochStyle optionsVariation2 = new OptionsJoshBlochStyle.Builder().option1("chrome").option2(2).build(); } } Now my "improved" version: public class Options { // note that these are not final private String option1; private int option2; // ...other options here public String getOption1() { return option1; } public int getOption2() { return option2; } public static class Builder { private final Options options = new Options(); public Builder option1(String option1) { this.options.option1 = option1; return this; } public Builder option2(int option2) { this.options.option2 = option2; return this; } public Options build() { return options; } } private Options() { } public static void main(String[] args) { Options optionsVariation1 = new Options.Builder().option1("firefox").option2(1).build(); Options optionsVariation2 = new Options.Builder().option1("chrome").option2(2).build(); } } As you can see in my "improved version", there are 2 less places in which we need to add code about any addition properties (or options, in this case)! The only negative that I can see is that the instance variables of the outer class are not able to be final. But, the class is still immutable without this. Is there really any downside to this improvement in maintainability? There has to be a reason which he repeated the properties within the nested class that I'm not seeing?

• Subterranean IL: Custom modifiers

  - by Simon Cooper

  In IL, volatile is an instruction prefix used to set a memory barrier at that instruction. However, in C#, volatile is applied to a field to indicate that all accesses on that field should be prefixed with volatile. As I mentioned in my previous post, this means that the field definition needs to store this information somehow, as such a field could be accessed from another assembly. However, IL does not have a concept of a 'volatile field'. How is this information stored? Attributes The standard way of solving this is to apply a VolatileAttribute or similar to the field; this extra metadata notifies the C# compiler that all loads and stores to that field should use the volatile prefix. However, there is a problem with this approach, namely, the .NET C++ compiler. C++ allows methods to be overloaded using properties, like volatile or const, on the parameters; this is perfectly legal C++: public ref class VolatileMethods { void Method(int *i) {} void Method(volatile int *i) {} } If volatile was specified using a custom attribute, then the VolatileMethods class wouldn't be compilable to IL, as there is nothing to differentiate the two methods from each other. This is where custom modifiers come in. Custom modifiers Custom modifiers are similar to custom attributes, but instead of being applied to an IL element separately to its declaration, they are embedded within the field or parameter's type signature itself. The VolatileMethods class would be compiled to the following IL: .class public VolatileMethods { .method public instance void Method(int32* i) {} .method public instance void Method( int32 modreq( [mscorlib]System.Runtime.CompilerServices.IsVolatile)* i) {} } The modreq([mscorlib]System.Runtime.CompilerServices.IsVolatile) is the custom modifier. This adds a TypeDef or TypeRef token to the signature of the field or parameter, and even though they are mostly ignored by the CLR when it's executing the program, this allows methods and fields to be overloaded in ways that wouldn't be allowed using attributes. Because the modifiers are part of the signature, they need to be fully specified when calling such a method in IL: call instance void Method( int32 modreq([mscorlib]System.Runtime.CompilerServices.IsVolatile)*) There are two ways of applying modifiers; modreq specifies required modifiers (like IsVolatile), and modopt specifies optional modifiers that can be ignored by compilers (like IsLong or IsConst). The type specified as the modifier argument are simple placeholders; if you have a look at the definitions of IsVolatile and IsLong they are completely empty. They exist solely to be referenced by a modifier. Custom modifiers are used extensively by the C++ compiler to specify concepts that aren't expressible in IL, but still need to be taken into account when calling method overloads. C++ and C# That's all very well and good, but how does this affect C#? Well, the C++ compiler uses modreq(IsVolatile) to specify volatility on both method parameters and fields, as it would be slightly odd to have the same concept represented using a modifier or attribute depending on what it was applied to. Once you've compiled your C++ project, it can then be referenced and used from C#, so the C# compiler has to recognise the modreq(IsVolatile) custom modifier applied to fields, and vice versa. So, even though you can't overload fields or parameters with volatile using C#, volatile needs to be expressed using a custom modifier rather than an attribute to guarentee correct interoperability and behaviour with any C++ dlls that happen to come along. Next up: a closer look at attributes, and how certain attributes compile in unexpected ways.

• SQL SERVER – What are Actions in SSAS and How to Make a Reporting Action

  - by Pinal Dave

  Actions are used for customized browsing and drilling of data for the end-user. It’s an event that a user can raise while accessing the cube data. They are used in cube browsers like excel and are triggered when a user in a client tool clicks on a particular member, level, dimension, cells or may be the cube itself.  For example a user might be able to see a reporting services report, open a web page or drill through to detailed information related to the cube data. Analysis server supports 3 types of actions :- Report Drill-through Standard Actions In this blog post, I will explain the Reporting  action. The objective of this action is to return a report with details of the product where the sales amount is greater than 1000 in cube browser analysis. You need to create a basic cube first with the facts and dimensions you want in the analysis. Following are the steps to create reporting action. Go to SQL server data tools and open the analysis services project. Navigate to actions and click on new reporting action. 2.) Specify the name of the action and choose target type as attribute members since we have to create the action on members for a attribute. 3.) Specify the Target object of your report action. Target object would be the dimension or attribute on which you want the report to appear. In our case it is product name. 4.) Next you have to define the condition on which you want the report link to appear. However, this is an optional feature. In this example we are specifying a condition, which will check if the sales amount is greater than 10,000. So, that the link appears only for those products where the defined condition is met. 5.) Next you have to specify the server name on which the report is present, report path  and the report format in which you want the report to appear. 6.) Additionally you can specify the parameters. As with conditional expression, the parameters should be a valid MDX expression. The parameter name should be same as the one defined in the report. 7.) Deploy your solution after you are done with specifying parameters and go to the cube browser. 8.) Click on the analyze in excel button, this will open your cube in excel 9.) Make an analysis which shows product names and their sales amount. 10.) Right click on a product where sales amount is greater than 10000 you will see the reporting action link. Click on that and you will be taken to your reporting services report. 11.) Clicking on the link will take you to the URL of the report. I created this report using report project wizard in SQL server data tools. So, this is how we can launch reports from a cube browser. Similarly you can open web pages, run applications and a number of  other tasks. Koenig Solutions offers SSAS training which contains all Analysis Services including Reporting in great detail. In my next blog post I will talk about drill-through actions. Author: Namita Sharma, Senior Corporate Trainer at Koenig Solutions.

• Unit Testing Framework for XQuery

  - by Knut Vatsendvik

  This posting provides a unit testing framework for XQuery using Oracle Service Bus. It allows you to write a test case to run your XQuery transformations in an automated fashion. When the test case is run, the framework returns any differences found in the response. The complete code sample with install instructions can be downloaded from here. Writing a Unit Test You start a new Test Case by creating a Proxy Service from Workshop that comes with Oracle Service Bus. In the General Configuration page select Service Type to be Messaging Service           In the Message Type Configuration page link both the Request & Response Message Type to the TestCase element of the UnitTest.xsd schema                 The TestCase element consists of the following child elements The ID and optional Name element is simply used for reference. The Transformation element is the XQuery resource to be executed. The Input elements represents the input to run the XQuery with. The Output element represents the expected output. These XML documents are “also” represented as an XQuery resource where the XQuery function takes no arguments and returns the XML document. Why not pass the test data with the TestCase? Passing an XML structure in another XML structure is not very easy or at least not very human readable. Therefore it was chosen to represent the test data as an loadable resource in the OSB. However you are free to go ahead with another approach on this if wanted. The XMLDiff elements represents any differences found. A sample on input is shown here. Modeling the Message Flow Then the next step is to model the message flow of the Proxy Service. In the Request Pipeline create a stage node that loads the test case input data.      For this, specify a dynamic XQuery expression that evaluates at runtime to the name of a pre-registered XQuery resource. The expression is of course set by the input data from the test case.           Add a Run stage node. Assign the result of the XQuery, that is to be run, to a context variable. Define a mapping for each of the input variables added in previous stage.     Add a Compare stage. Like with the input data, load the expected output data. Do a compare using XMLDiff XQuery provided where the first argument is the loaded output test data, and the second argument the result from the Run stage. Any differences found is replaced back into the test case XMLDiff element. In case of any unexpected failure while processing, add an Error Handler to the Pipeline to capture the fault. To pass back the result add the following Insert action In the Response Pipeline. A sample on output is shown here.

• I love it when a plan comes together

  - by DavidWimbush

  I'm currently working on an application so that our Marketing department can produce most of their own mailing lists without my having to get involved. It was all going well until I got stuck on the bit where the actual SQL query is generated but a rummage in Books Online revealed a very clean solution using some constructs that I had previously dismissed as pointless. Typically we want to email every customer who is in any of the following n groups. Experience shows that a group has the following definition: <people who have done A> [(AND <people who have done B>) | (OR <people who have done C>)] [APART FROM <people who have done D>] When doing these by hand I've been using INNER JOIN for the AND, UNION for the OR, and LEFT JOIN + WHERE D IS NULL for the APART FROM. This would produce two quite different queries: -- Old OR select  A.PersonID from  (   -- A   select  PersonID   from  ...   union  -- OR   -- C   select  PersonID   from  ...   ) AorC   left join  -- APART FROM   (   select  PersonID   from  ...   ) D on D.PersonID = AorC.PersonID where  D.PersonID is null -- Old AND select  distinct main.PersonID from  (   -- A   select  PersonID   from  ...   ) A   inner join  -- AND   (   -- B   select  PersonID   from  ...   ) B on B.PersonID = A.PersonID   left join  -- APART FROM   (   select  PersonID   from  ...   ) D on D.PersonID = A.PersonID where  D.PersonID is null But when I tried to write the code that can generate the SQL for any combination of those (along with all the variables controlling what each SELECT did and what was in all the optional bits of each WHERE clause) my brain started to hurt. Then I remembered reading about the (then new to me) keywords INTERSECT and EXCEPT. At the time I couldn't see what they added but I thought I would have a play and see if they might help. They were perfect for this. Here's the new query structure: -- The way forward select  PersonID from  (     (       (       -- A       select  PersonID       from  ...       )       union      -- OR        intersect  -- AND       (       -- B/C       select  PersonID       from  ...       )     )     except     (     -- D     select  PersonID     from  ...     )   ) x I can easily swap between between UNION and INTERSECT, and omit B, C, or D as necessary. Elegant, clean and readable - pick any 3! Sometimes it really pays to read the manual.
