  • Cannot start `Routing and Remote Access Service` and it's dependencies

    - by ahmadali shafiee
    I tried to start Routing and Remote Access Service but I've got an error says the dependency service or group failed to start then I tried to start Remote Access Connection Manager (one of RRAS's dependencies) and the error way same. then I tried to start The Secure Socket Tuning Protocol Service but there was an error says that the the service started then stopped! the errors form event log is here: The Remote Access Connection Manager service depends on the Secure Socket Tunneling Protocol Service service which failed to start because of the following error: The operation completed successfully. The Secure Socket Tunneling Protocol Service service entered the stopped state. The Routing and Remote Access service depends on the Remote Access Connection Manager service which failed to start because of the following error: The dependency service or group failed to start. sort by date Does anyone know how can I resolve the problem?

  • How do I prevent rpmbuild form injecting requirements into RPM package?

    - by Basilevs
    I'm creating an RPM package from native Python 2.5 one. Out corporate policy is to use python2.4 by default, so I'm adding a string Requires: python25 to a .spec file. When I look at created RPM file though, i see the following dependencies: rpm -qR -p ZSI-2.1_a1-py25.noarch.rpm /usr/bin/python2.5 python(abi) = 2.5 python25 rpmlib(CompressedFileNames) <= 3.0.4-1 rpmlib(PayloadFilesHavePrefix) <= 4.0-1 Dependency added by me is present, but other dependencies are also here. I'm unable to provide python(abi) = 2.5 dependency, because of dumb python25 package generated by our IT department where provides tag is incorrect. How do I remove automatically added dependencies from generated RPM?

  • How can I install mod_dav_svn 1.6 on CentOS 5.4?

  • Debian/Ubuntu: Enabling "dist-upgrade" behavior for unattended-upgrades?

    - by Mark Renouf
    We've got a customized distribution of Ubuntu, a repository with some custom packages and we run unattended-upgrades on a number of systems. What we want to be able to do is supply an update of one of our packages which might have a new dependency which is not yet installed. I understand apt normally prevents that from happening automatically, and using dist-upgrade would permit it. How can I get that behavior so our unattended upgrades work the same way? Ideally we'd only want new packages installed if one of our packages causes it to be needed (either as a direct dependency or a child, etc.) Should I be aware of any potential problems or increased risk of breakage. The systems are generally not easily accessed via the console so anything causing a problem requiring manual intervention would be very bad!

  • Installing multiple versions of a shared library

    - by nsfyn55
    I am running ubuntu 10.04 and I want to use tmux 1.6. tmux has a dependency on libevent 2. My solution was to compile libevent2 and drop into /usr/local/lib then compile tmux against this lib and drop into /usr/local/bin. This works great until...I restart. This is just an assumption on my part but it seems that other binaries are now linking to the libevent2 library presumably because its on the library path. Because there are 60+ packages with libevent1 dependencies this causes my install to basically lose its mind. Is there an idiomatic way to approach running an application that has a core library dependency on a different version? Should I just statically link the lib?

  • Lightweight alternative to R for RHEL?

    - by Eric Rath
    I want to use R for some statistical analysis of logfile information, but found that even the "limited" R-core RPM has a lot of dependencies not already installed. I don't want to install so many packages for a peripheral need. Are there lightweight alternatives for simple statistical analysis on RHEL 6? I have an R script that accepts on stdin a large set of values -- one value per line -- and prints out the min, max, mean, median, 95th percentile, and standard deviation. For more context, I'm using grep and awk to find GET requests for a particular path in our webserver log files, get the response times, and calculate the metrics listed above in order to measure the impact on performance of changes to a web application. I don't need any graphing capabilities, just simple computation. Is there something I've overlooked?

  • Solr WordDelimiterFilter + Lucene Highlighter

    - by Lucas
    I am trying to get the Highlighter class from Lucene to work properly with tokens coming from Solr's WordDelimiterFilter. It works 90% of the time, but if the matching text contains a ',' such as "1,500" the output is incorrect: Expected: 'test 1,500 this' Observed: 'test 11,500 this' I am not currently sure whether it is Highlighter messing up the recombination or WordDelimiterFilter messing up the tokenization but something is unhappy. Here are the relevant dependencies from my pom: org.apache.lucene lucene-core 2.9.3 jar compile org.apache.lucene lucene-highlighter 2.9.3 jar compile org.apache.solr solr-core 1.4.0 jar compile And here is a simple JUnit test class demonstrating the problem: package test.lucene; import static org.junit.Assert.assertEquals; import static org.junit.Assert.assertTrue; import java.io.IOException; import java.io.Reader; import java.util.HashMap; import org.apache.lucene.analysis.Analyzer; import org.apache.lucene.analysis.TokenStream; import org.apache.lucene.queryParser.ParseException; import org.apache.lucene.queryParser.QueryParser; import org.apache.lucene.search.Query; import org.apache.lucene.search.highlight.Highlighter; import org.apache.lucene.search.highlight.InvalidTokenOffsetsException; import org.apache.lucene.search.highlight.QueryScorer; import org.apache.lucene.search.highlight.SimpleFragmenter; import org.apache.lucene.search.highlight.SimpleHTMLFormatter; import org.apache.lucene.util.Version; import org.apache.solr.analysis.StandardTokenizerFactory; import org.apache.solr.analysis.WordDelimiterFilterFactory; import org.junit.Test; public class HighlighterTester { private static final String PRE_TAG = "<b>"; private static final String POST_TAG = "</b>"; private static String[] highlightField( Query query, String fieldName, String text ) throws IOException, InvalidTokenOffsetsException { SimpleHTMLFormatter formatter = new SimpleHTMLFormatter( PRE_TAG, POST_TAG ); Highlighter highlighter = new Highlighter( formatter, new QueryScorer( query, fieldName ) ); highlighter.setTextFragmenter( new SimpleFragmenter( Integer.MAX_VALUE ) ); return highlighter.getBestFragments( getAnalyzer(), fieldName, text, 10 ); } private static Analyzer getAnalyzer() { return new Analyzer() { @Override public TokenStream tokenStream( String fieldName, Reader reader ) { // Start with a StandardTokenizer TokenStream stream = new StandardTokenizerFactory().create( reader ); // Chain on a WordDelimiterFilter WordDelimiterFilterFactory wordDelimiterFilterFactory = new WordDelimiterFilterFactory(); HashMap<String, String> arguments = new HashMap<String, String>(); arguments.put( "generateWordParts", "1" ); arguments.put( "generateNumberParts", "1" ); arguments.put( "catenateWords", "1" ); arguments.put( "catenateNumbers", "1" ); arguments.put( "catenateAll", "0" ); wordDelimiterFilterFactory.init( arguments ); return wordDelimiterFilterFactory.create( stream ); } }; } @Test public void TestHighlighter() throws ParseException, IOException, InvalidTokenOffsetsException { String fieldName = "text"; String text = "test 1,500 this"; String queryString = "1500"; String expected = "test " + PRE_TAG + "1,500" + POST_TAG + " this"; QueryParser parser = new QueryParser( Version.LUCENE_29, fieldName, getAnalyzer() ); Query q = parser.parse( queryString ); String[] observed = highlightField( q, fieldName, text ); for ( int i = 0; i < observed.length; i++ ) { System.out.println( "\t" + i + ": '" + observed[i] + "'" ); } if ( observed.length > 0 ) { System.out.println( "Expected: '" + expected + "'\n" + "Observed: '" + observed[0] + "'" ); assertEquals( expected, observed[0] ); } else { assertTrue( "No matches found", false ); } } } Anyone have any ideas or suggestions?

  • Problems with maven output directory

    - by Gandalf StormCrow
    I'm using almost same POM for both my projects, they are on the same workspace but they are not related at all, they are related however because in both I use spring and jboss. Here is the pom : <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.springinaction.hello</groupId> <artifactId>spring-in-action</artifactId> <packaging>jar</packaging> <version>0.0.1-SNAPSHOT</version> <name>spring-in-action</name> <url>http://maven.apache.org</url> <properties> <jboss.ome>C:\jboss-5.1.0.GA\server\default\deploy</jboss.ome> <springversion>2.5.3</springversion> </properties> <dependencies> <dependency> <groupId>org.springframework</groupId> <artifactId>spring</artifactId> <version>${springversion}</version> </dependency> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.14</version> <scope>provided</scope> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-war-plugin</artifactId> <version>2.0</version> <configuration> <warName>spring-book</warName> <outputDirectory>${jboss.ome}</outputDirectory> </configuration> </plugin> </plugins> </build> </project> What I want to achieve with this POM is that I want to name my war when built spring-book.war and copy it to Jboss location I specified. Now in my first project this works it does exactly what I requested but in other it does not. I changed springversion and jboss home properties variable but everything remains the same, what can I do ? The project builds and all, everything is working perfectly just I don't want to copy everytime in my jboss dir and previously remove the old war, it takes about 20sec on each source code change its a lot

  • Applying Unity in dynamic menu

    - by Rajarshi
    I was going through Unity 2.0 to check if it has an effective use in our new application. My application is a Windows Forms application and uses a traditional bar menu (at the top), currently. My UIs (Windows Forms) more or less support Dependency Injection pattern since they all work with a class (Presentation Model Class) supplied to them via the constructor. The form then binds to the properties of the supplied P Model class and calls methods on the P Model class to perform its duties. Pretty simple and straightforward. How P Model reacts to the UI actions and responds to them by co-ordinating with the Domain Class (Business Logic/Model) is irrelevant here and thus not mentioned. The object creation sequence to show up one UI from menu then goes like this - Create Business Model instance Create Presentation Model instance with Business Model instance passed to P Model constructor. Create UI instance with Presentation Model instance passed to UI constructor. My present solution: To show an UI in the method above from my menu I would have to refer all assemblies (Business, PModel, UI) from my Menu class. Considering I have split the modules into a number of physical assemblies, that would be a dificult task to add references to about 60 different assemblies. Also the approach is not very scalable since I would certainly need to release more modules and with this approach I would have to change the source code every time I release a new module. So primarily to avoid the reference of so many assemblies from my Menu class (assembly) I did as below - Stored all the dependency described above in a database table (SQL Server), e.g. ModuleShortCode | BModelAssembly | BModelFullTypeName | PModelAssembly | PModelFullTypeName | UIAssembly | UIFullTypeName Now used a static class named "Launcher" with a method "Launch" as below - Launcher.Launch("Discount") Launcher.Launch("Customers") The Launcher internally uses data from the dependency table and uses Activator.CreateInstance() to create each of the objects and uses the instance as constructor parameter to the next object being created, till the UI is built. The UI is then shown as a modal dialog. The code inside Launcher is somewhat like - Form frm = ResolveForm("Discount"); frm.ShowDialog(); The ResolveForm does the trick of building the chain of objects. Can Unity help me here? Now when I did that I did not have enough information on Unity and now that I have studied Unity I think I have been doing more or less the same thing. So I tried to replace my code with Unity. However, as soon as I started I hit a block. If I try to resolve UI forms in my Menu as Form customers = myUnityContainer.Resolve(); or Form customers = myUnityContainer.Resolve(typeof(Customers)); Then either way, I need to refer to my UI assembly from my Menu assembly since the target Type "Customers" need to be known for Unity to resolve it. So I am back to same place since I would have to refer all UI assemblies from the Menu assembly. I understand that with Unity I would have to refer fewer assemblies (only UI assemblies) but those references are needed which defeats my objectives below - Create the chain of objects dynamically without any assembly reference from Menu assembly. This is to avoid Menu source code changing every time I release a new module. My Menu also is built dynamically from a table. Be able to supply new modules just by supplying the new assemblies and inserting the new Dependency row in the table by a database patch. At this stage, I have a feeling that I have to do it the way I was doing, i.e. Activator.CreateInstance() to fulfil all my objectives. I need to verify whether the community thinks the same way as me or have a better suggestion to solve the problem. The post is really long and I sincerely thank you if you come til this point. Waiting for your valuable suggestions. Rajarshi

    Introduction:          ASP.NET MVC 3 just released by ASP.NET MVC team which includes some new features, some changes, some improvements and bug fixes. In this article, I will show you the new features of ASP.NET MVC 3. This will help you to get started using the new features of ASP.NET MVC 3. Full details of this announcement is available at Announcing release of ASP.NET MVC 3, IIS Express, SQL CE 4, Web Farm Framework, Orchard, WebMatrix.   Description:       New Razor View Engine:              Razor view engine is one of the most coolest new feature in ASP.NET MVC 3. Razor is speeding things up just a little bit more. It is much smaller and lighter in size. Also it is very easy to learn. You can say ' write less, do more '. You can get start and learn more about Razor at Introducing “Razor” – a new view engine for ASP.NET.         Granular Request Validation:             Another biggest new feature in ASP.NET MVC 3 is Granular Request Validation. Default request validator will throw an exception when he see < followed by an exclamation(like <!) or < followed by the letters a through z(like <s) or & followed by a pound sign(like &#123) as a part of querystring, posted form, headers and cookie collection. In previous versions of ASP.NET MVC, you can control request validation using ValidateInputAttriubte. In ASP.NET MVC 3 you can control request validation at Model level by annotating your model properties with a new attribute called AllowHtmlAttribute. For details see Granular Request Validation in ASP.NET MVC 3.       Sessionless Controller Support:             Sessionless Controller is another great new feature in ASP.NET MVC 3. With Sessionless Controller you can easily control your session behavior for controllers. For example, you can make your HomeController's Session as Disabled or ReadOnly, allowing concurrent request execution for single user. For details see Concurrent Requests In ASP.NET MVC and HowTo: Sessionless Controller in MVC3 – what & and why?.       Unobtrusive Ajax and  Unobtrusive Client Side Validation is Supported:             Another cool new feature in ASP.NET MVC 3 is support for Unobtrusive Ajax and Unobtrusive Client Side Validation.  This feature allows separation of responsibilities within your web application by separating your html with your script. For details see Unobtrusive Ajax in ASP.NET MVC 3 and Unobtrusive Client Validation in ASP.NET MVC 3.       Dependency Resolver:             Dependency Resolver is another great feature of ASP.NET MVC 3. It allows you to register a dependency resolver that will be used by the framework. With this approach your application will not become tightly coupled and the dependency will be injected at run time. For details see ASP.NET MVC 3 Service Location.       New Helper Methods:             ASP.NET MVC 3 includes some helper methods of ASP.NET Web Pages technology that are used for common functionality. These helper methods includes: Chart, Crypto, WebGrid, WebImage and WebMail. For details of these helper methods, please see ASP.NET MVC 3 Release Notes. For using other helper methods of ASP.NET Web Pages see Using ASP.NET Web Pages Helpers in ASP.NET MVC.       Child Action Output Caching:             ASP.NET MVC 3 also includes another feature called Child Action Output Caching. This allows you to cache only a portion of the response when you are using Html.RenderAction or Html.Action. This cache can be varied by action name, action method signature and action method parameter values. For details see this.       RemoteAttribute:             ASP.NET MVC 3 allows you to validate a form field by making a remote server call through Ajax. This makes it very easy to perform remote validation at client side and quickly give the feedback to the user. For details see How to: Implement Remote Validation in ASP.NET MVC.       CompareAttribute:             ASP.NET MVC 3 includes a new validation attribute called CompareAttribute. CompareAttribute allows you to compare the values of two different properties of a model. For details see CompareAttribute in ASP.NET MVC 3.       Miscellaneous New Features:                    ASP.NET MVC 2 includes FormValueProvider, QueryStringValueProvider, RouteDataValueProvider and HttpFileCollectionValueProvider. ASP.NET MVC 3 adds two additional value providers, ChildActionValueProvider and JsonValueProvider(JsonValueProvider is not physically exist).  ChildActionValueProvider is used when you issue a child request using Html.Action and/or Html.RenderAction methods, so that your explicit parameter values in Html.Action and/or Html.RenderAction will always take precedence over other value providers. JsonValueProvider is used to model bind JSON data. For details see Sending JSON to an ASP.NET MVC Action Method Argument.           In ASP.NET MVC 3, a new property named FileExtensions added to the VirtualPathProviderViewEngine class. This property is used when looking up a view by path (and not by name), so that only views with a file extension contained in the list specified by this new property is considered. For details see VirtualPathProviderViewEngine.FileExtensions Property .           ASP.NET MVC 3 installation package also includes the NuGet Package Manager which will be automatically installed when you install ASP.NET MVC 3. NuGet makes it easy to install and update open source libraries and tools in Visual Studio. See this for details.           In ASP.NET MVC 2, client side validation will not trigger for overridden model properties. For example, if have you a Model that contains some overridden properties then client side validation will not trigger for overridden properties in ASP.NET MVC 2 but client side validation will work for overridden properties in ASP.NET MVC 3.           Client side validation is not supported for StringLengthAttribute.MinimumLength property in ASP.NET MVC 2. In ASP.NET MVC 3 client side validation will work for StringLengthAttribute.MinimumLength property.           ASP.NET MVC 3 includes new action results like HttpUnauthorizedResult, HttpNotFoundResult and HttpStatusCodeResult.           ASP.NET MVC 3 includes some new overloads of LabelFor and LabelForModel methods. For details see LabelExtensions.LabelForModel and LabelExtensions.LabelFor.           In ASP.NET MVC 3, IControllerFactory includes a new method GetControllerSessionBehavior. This method is used to get controller's session behavior. For details see IControllerFactory.GetControllerSessionBehavior Method.           In ASP.NET MVC 3, Controller class includes a new property ViewBag which is of type dynamic. This property allows you to access ViewData Dictionary using C # 4.0 dynamic features. For details see ControllerBase.ViewBag Property.           ModelMetadata includes a property AdditionalValues which is of type Dictionary. In ASP.NET MVC 3 you can populate this property using AdditionalMetadataAttribute. For details see AdditionalMetadataAttribute Class.           In ASP.NET MVC 3 you can also use MvcScaffolding to scaffold your Views and Controller. For details see Scaffold your ASP.NET MVC 3 project with the MvcScaffolding package.           If you want to convert your application from ASP.NET MVC 2 to ASP.NET MVC 3 then there is an excellent tool that automatically converts ASP.NET MVC 2 application to ASP.NET MVC 3 application. For details see MVC 3 Project Upgrade Tool.           In ASP.NET MVC 2 DisplayAttribute is not supported but in ASP.NET MVC 3 DisplayAttribute will work properly.           ASP.NET MVC 3 also support model level validation via the new IValidatableObject interface.           ASP.NET MVC 3 includes a new helper method Html.Raw. This helper method allows you to display unencoded HTML.     Summary:          In this article I showed you the new features of ASP.NET MVC 3. This will help you a lot when you start using ASP MVC 3. I also provide you the links where you can find further details. Hopefully you will enjoy this article too.

  • C# 5.0 Async/Await Demo Code

    - by Paulo Morgado
    I’ve published the sample code I use to demonstrate the use of async/await in C# 5.0. You can find it here. Projects PauloMorgado.AyncDemo.WebServer This project is a simple web server implemented as a console application using Microsoft ASP.NET Web API self hosting and serves an image (with a delay) that is accessed by the other projects. This project has a dependency on Json.NET due to the fact the the Microsoft ASP.NET Web API hosting has a dependency on Json.NET. The application must be run on a command prompt with administrative privileges or a urlacl must be added to allow the use of the following command: netsh http add urlacl url=http://+:9090/ user=machine\username To remove the urlacl, just use the following command: netsh http delete urlacl url=http://+:9090/ PauloMorgado.AsyncDemo.WindowsForms This Windows Forms project contains three regions that must be uncommented one at a time: Sync with WebClient This code retrieves the image through a synchronous call using the WebClient class. Async with WebClient This code retrieves the image through an asynchronous call using the WebClient class. Async with HttpClient with cancelation This code retrieves the image through an asynchronous call with cancelation using the HttpClient class.

  • Upgrading from 2005 to R2

    - by DavidWimbush
    We're about to take the plunge and upgrade our servers from SQL 2005 to SQL 2008 R2. Real world accounts of people upgrading to R2 are a bit hard to find so I thought it might be useful to blog what happens. (I don't count marketing 'case studies' that just say stuff like "The process was effortless and the upgrade will pay for itself by the end the week.") We're using the database engine, Analysis Services and Reporting Services so upgrading by a major version number was looking a bit daunting. I wasn't expecting much trouble on the engine side of things but, as most of the action in 2008 and R2 appears to have been on the Reporting and BI front, I expected to have quite a bit of work to do. But our testing so far has been one nice surprise after another: The 2005 backups restore cleanly onto R2. R2's BI Studio upgraded the Reporting and Analysis Services solutions without any issues. The cubes all deployed and processed just fine. R2 BI Studio interacts fine with TFS 2008 version control. I'll blog some more as things develop.

  • Unity Plugin DLLNotFoundException

    - by Dewayne
    I am using a plugin DLL that I created in Visual C++ Express 2010 on windows 7 64 bit Ultimate Edition. The DLL functions properly on the machine that it was originally created on. The problem is that the DLL is not functioning in the Unity3d Editor on another machine and giving an error that basically states that the DLL is missing some of its dependencies. The target machine is running Windows 7 Home 64 bit (if this is relevant) Results from the error log of Dependency Walker: Error: The Side-by-Side configuration information for "c:\users\dewayne\desktop\shared\vrpnplugin\unityplugin\build\release\OPTITRACKPLUGIN.DLL" contains errors. The application has failed to start because its side-by-side configuration is incorrect. Please see the application event log or use the command-line sxstrace.exe tool for more detail (14001). Error: At least one module has an unresolved import due to a missing export function in an implicitly dependent module. Error: Modules with different CPU types were found. Warning: At least one delay-load dependency module was not found. Warning: At least one module has an unresolved import due to a missing export function in a delay-load dependent module. The Visual C++ Express 2010 project and solution file can be found here: https://docs.google.com/leaf?id=0B1F4pP7mRSiYMGU2YTJiNTUtOWJiMS00YTYzLThhYWQtMzNiOWJhZDU5M2M0&hl=en&authkey=CJSXhqgH The zip is 79MB and also contains its dependencies.

  • How Can I Install LibreOffice Base?

    - by Rob
    Useful info: I have tried running sudo dpkg --configure -a and sudo apt-get install -f with no result. I am running Kubuntu 11.10 (the updater is far too unreliable to ever be trusted with performing a version upgrade) The rest of LibreOffice seems to work fine (apart from an annoying bug where tooltips are shown as black text on black background...) I have need to use LibreOffice Base to complete a mail merge document. However, I noticed it's not installed. When I go to install it however... rob@hydrogen:~$ sudo apt-get install libreoffice-base [sudo] password for rob: Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies. libreoffice-base : Depends: libreoffice-core (= 1:3.4.4-0ubuntu1) but it is not going to be installed Depends: libreoffice-base-core (= 1:3.4.4-0ubuntu1) but it is not going to be installed Depends: libreoffice-java-common (>= 1:3.4.4~) but it is not going to be installed Suggests: libmyodbc but it is not going to be installed or odbc-postgresql but it is not going to be installed or libsqliteodbc but it is not going to be installed or tdsodbc but it is not going to be installed or mdbtools but it is not going to be installed Suggests: libreoffice-gcj but it is not installable Suggests: libreoffice-report-builder but it is not going to be installed E: Unable to correct problems, you have held broken packages. I'm bemused as to which packages it seems to think I have held. As far as I'm aware, Kubuntu doesn't give you the option to hold packages... So, how do I get out of this dependency hell?

  • Tuning Red Gate: #5 of Multiple

    - by Grant Fritchey
    In the Tuning Red Gate series I've shown you how to look at a current load on the system and how to drill down to look at historical analysis of the system. I've also shown how you can see the top queries and other information from the current status of the system. I have one more thing I can show you before we need to start fixing things and showing how that affects the data collected, historical moments in time. For example, back in Post #3 I was looking at some spikes in some of the monitored resources that were taking place a couple of weeks back in time. Once I identify a moment in time that I'm interested in, I can go back to the first page of Monitor, Global Overview, and click on the icon: From this you can select the date and time you're interested in. For example, I saw some serious CPU queues last week: This then rolls back the time for all the information that's available to the Global Overview and the drill down to the server and the SQL Server instance there. This then allows me to look at the Top Queries running at this point, sort them by CPU and identify what was potentially the query that was causing the problem right when I saw the CPU queuing This ability to correlate a moment in time with the information available to you in the Analysis window makes for an excellent tool to investigate your systems going backwards in time. It really makes a huge difference in your knowledge. It's not enough to know that something happened at a particular time. You need to know what it was that was occurring. Remember, the key to tuning your systems is having enough knowledge about them. I'll post more on Tuning Red Gate as soon as I can get some queries rewritten. I'm working on that.

  • How to conciliate OOAD and Database Design?

    - by user1620696
    Recently I've studied about object oriented analysis and design and I liked a lot about it. In every place I've read people say that the idea is to start with the minimum set of requirements and go improving along the way, revisiting this each iteration and making it better as we contiuously develop and contact the customer interested in the software. In particular, one course from Lynda.com said a lot of that: we don't want to spend a lot of time planing everything upfront, we just want to have the minimum to get started and then improve this each iteration. Now, I've also seem a course from the same guy about database design, and there he says differently. He says that although when working with object orientation he likes the agile iterative approach, for database design we should really spend a lot of time planing things upfront instead of just going along the way with the minimum. But this confuses me a little. Indeed, the database will persist important data from our domain model and perhaps configurations of the software and so on. Now, if I'm going to continuously revist the analysis and design of the model, it seems the database design should change also. In the same way, if we plan all the database upfront it seems we are also planing all the model upfront, so the two ideas seems to be incompatible. I really like agile iterative approach, but I'm also looking at getting better design for the database also, so when working with agile iterative approach, how should we deal with the database design?
