Drupal Modules for SEO & Content

- by Aditi

When we talk about Drupal SEO, there are two things to consider one is about the relevant SEO practices and about appropriate Drupal Modules available. Optimizing your website for search engines is one of the most important aspect of launching & promoting your website especially if ranking matters to you. Understanding SEO For starters, you have begin with Keyword research and then optimize your content according to your findings by tagging, meta tags etc, Drupal modules once installed help you manage a lot of such parameters. Identifying the target keywords Using the Page Title and Token modules PathAuto configuration <H1> heading tags Optimizing Drupal’s default robots.txt file Etc. While Drupal gives you a lot of ability to make your website content worthy & search engine friendly it is important for you to make sure you are not crossing the line or you could get penalized. Modules Overview Drupal Power is at its best when you have these modules & great brain working together. The basic SEO improvements can be achieved easily with the modules enlisted below, but you can win magical rankings if you use them logically & wisely. Understanding your keyword competition & enhancing your content is the basic key to success and ofcourse the modules: Pathauto Automatically create search enging friendly readable URLS from tokens. A token is a piece of data from content, say the author’s username, or the content’s title. For example mysite.com/an-article, rather than mysite.com/node/114 for every node you make. NodeWords Amazingly useful drupal module that allows you to create custom meta tags and descriptions for your nodes, which gives you the ability to target specific keywords and phrases. Page Title Enables you to set an alternative title for the <title></title> tags and for the <h1></h1> tags on a node. Global Redirect Manage content duplication, 301 redirects, and URL validation with this small, but powerful module. Taxonomy manager Make large additions, or changes to taxonomy very easy. This module provides a powerful interface for managing taxonomies. A vocabulary gets displayed in a dynamic tree view, where parent terms can be expanded to list their nested child terms or can be collapsed. robotstxt A robots.txt file is vital for ensuring that search engine spiders don’t index the unwanted areas of your site. This Drupal module gives you the ability to manage your robots.txt file through the CMS admin. xmlsitemap An XML Sitemap lets the search engines index your website content. This module helps in generating and maintaining a complete sitemap for your website and gives you control over exactly which parts of the site you want to be included in the index. It even gives you the ability to automatically submit your sitemap to Google, Yahoo!, Ask.com and Windows Live every time you update a node or at specific interval. Node Import This module allows you to import a set of nodes from a Comma Seperated Values (CSV) or Tab Seperated Values (TSV) text file. Makes it easy to import hundreds-thousands of csv rows and you get to tie up these rows to CCK fields (or locations), and it can file it under the right taxonomy hierarchy. This is Super life saver module.

Time to stop using “Execute Package Task”– a way to execute package in SSIS catalog taking advantage of the new project deployment model ,and the logging and reporting feature

- by Kevin Shyr

I set out to find a way to dynamically call package in SSIS 2012. The following are 2 excellent blogs I found; I used them heavily. The code below has some addition to parameter types and message types, but was made essentially derived entirely from the blogs. http://sqlblog.com/blogs/jamie_thomson/archive/2011/07/16/ssis-logging-in-denali.aspx http://www.ssistalk.com/2012/07/24/quick-tip-run-ssis-2012-packages-synchronously-and-other-execution-options/ The code: Every package will be called by a PackageController package. The packageController is initialized with some information on which package to run and what information to pass in. The following is the stored procedure called from the “Execute SQL Task”. Here is the highlight of the stored procedure It takes in packageName, project name, and folder name (folder in SSIS project deployment to SSIS catalog) The stored procedure sets the package variables of the upcoming package execution Execute package in SSIS Catalog Get the status of the execution. Also, if exists, get the error message’s message_id and store them in the management database. Return value to “Execute SQL Task” to manage failure properly CREATE PROCEDURE [AUDIT].[LaunchPackageExecutionInSSISCatalog] @PackageName NVARCHAR(255) , @ProjectFolder NVARCHAR(255) , @ProjectName NVARCHAR(255) , @AuditKey INT , @DisableNotification BIT , @PackageExecutionLogID INT AS BEGIN TRY DECLARE @execution_id BIGINT = 0;

OWB 11gR2 - Find and Search Metadata in Designer

- by David Allan

Here are some tools and techniques for finding objects, specifically in the design repository. There are ways of navigating and collating objects that are useful for day to day development and build-time usage - this includes features out of the box and utilities constructed on top. There are a variety of techniques to navigate and find objects in the repository, the first 3 are out of the box, the 4th is an expert utility. Navigating by the tree, grouping by project and module - ok if you are aware of the exact module/folder that objects reside in. The structure panel is a useful way of finding parts of an object, especially when large rather than using the canvas. In large scale projects it helps to have accelerators (either find or collections below). Advanced find to search by name - 11gR2 included a find capability specifically for large scale projects. There were improvements in both the tree search and the object editors (including highlighting in mapping for example). So you can now do regular expression based search and quickly navigate to objects within a repository. Collections - logically organize your objects into virtual folders by shortcutting the actual objects. This is useful for a range of things since all the OWB services operate on collections too (export/import, validation, deployment). See the post here for new collection functionality in 11gR2. Reports for searching by type, updated on, updated by etc. Useful for activities such as periodic incremental actions (deploy all mappings changed in the past week). The report style view is useful since I can quickly see who changed what and when. You can see all the audit details for objects within each objects property inspector, but its useful to just get all objects changed today or example, all objects changed since my last build etc. This utility combines both UI extensions via experts and the public views on the repository. In the figure to the right you see the contextual option 'Object Search' which invokes the utility, you can see I have quite a number of modules within my project. Figure out all the potential objects which have been changed is not simple. The utility is an expert which provides this kind of search capability. The utility provides a report of the objects in the design repository which satisfy some filter criteria. The type of criteria includes; objects updated in the last n days optionally filter the objects updated by user filter the user by project and by type (table/mappings etc.) The search dialog appears with these options, you can multi-select the object types, so for example you can select TABLE and MAPPING. Its also possible to search across projects if need be. If you have multiple users using the repository you can define the OWB user name in the 'Updated by' property to restrict the report to just that user also. Finally there is a search name that will be used for some of the options such as building a collection - this name is used for the collection to be built. In the example I have done, I've just searched my project for all process flows and mappings that users have updated in the last 7 days. The results of the query are returned in a table containing the object names, types, full path and audit details. The columns are sort-able, you can sort the results by name, type, path etc. One of the cool things here, is that you can then perform operations on these objects - such as edit them, export single selection or entire results to MDL, create a collection from the results (now you have a saved set of references in the repository, you could do deploy/export etc.), create a deployment script from the results...or even add in your own ideas! You see from this that you can do bulk operations on sets of objects based on search results. So for example selecting the 'Build Collection' option creates a collection with all of the objects from my search, you can subsequently deploy/generate/maintain this collection of objects. Under the hood of the expert if just basic OMB commands from the product and the use of the public views on the design repository. You can see how easy it is to build up macro-like capabilities that will help you do day-to-day as well as build like tasks on sets of objects.

WCF RIA Services DomainContext Abstraction Strategies–Say That 10 Times!

- by dwahlin

The DomainContext available with WCF RIA Services provides a lot of functionality that can help track object state and handle making calls from a Silverlight client to a DomainService. One of the questions I get quite often in our Silverlight training classes (and see often in various forums and other areas) is how the DomainContext can be abstracted out of ViewModel classes when using the MVVM pattern in Silverlight applications. It’s not something that’s super obvious at first especially if you don’t work with delegates a lot, but it can definitely be done. There are various techniques and strategies that can be used but I thought I’d share some of the core techniques I find useful. To start, let’s assume you have the following ViewModel class (this is from my Silverlight Firestarter talk available to watch online here if you’re interested in getting started with WCF RIA Services): public class AdminViewModel : ViewModelBase { BookClubContext _Context = new BookClubContext(); public AdminViewModel() { if (!DesignerProperties.IsInDesignTool) { LoadBooks(); } } private void LoadBooks() { _Context.Load(_Context.GetBooksQuery(), LoadBooksCallback, null); } private void LoadBooksCallback(LoadOperation<Book> books) { Books = new ObservableCollection<Book>(books.Entities); } } Notice that BookClubContext is being used directly in the ViewModel class. There’s nothing wrong with that of course, but if other ViewModel objects need to load books then code would be duplicated across classes. Plus, the ViewModel has direct knowledge of how to load data and I like to make it more loosely-coupled. To do this I create what I call a “Service Agent” class. This class is responsible for getting data from the DomainService and returning it to a ViewModel. It only knows how to get and return data but doesn’t know how data should be stored and isn’t used with data binding operations. An example of a simple ServiceAgent class is shown next. Notice that I’m using the Action<T> delegate to handle callbacks from the ServiceAgent to the ViewModel object. Because LoadBooks accepts an Action<ObservableCollection<Book>>, the callback method in the ViewModel must accept ObservableCollection<Book> as a parameter. The callback is initiated by calling the Invoke method exposed by Action<T>: public class ServiceAgent { BookClubContext _Context = new BookClubContext(); public void LoadBooks(Action<ObservableCollection<Book>> callback) { _Context.Load(_Context.GetBooksQuery(), LoadBooksCallback, callback); } public void LoadBooksCallback(LoadOperation<Book> lo) { //Check for errors of course...keeping this brief var books = new ObservableCollection<Book>(lo.Entities); var action = (Action<ObservableCollection<Book>>)lo.UserState; action.Invoke(books); } } This can be simplified by taking advantage of lambda expressions. Notice that in the following code I don’t have a separate callback method and don’t have to worry about passing any user state or casting any user state (the user state is the 3rd parameter in the _Context.Load method call shown above). public class ServiceAgent { BookClubContext _Context = new BookClubContext(); public void LoadBooks(Action<ObservableCollection<Book>> callback) { _Context.Load(_Context.GetBooksQuery(), (lo) => { var books = new ObservableCollection<Book>(lo.Entities); callback.Invoke(books); }, null); } } A ViewModel class can then call into the ServiceAgent to retrieve books yet never know anything about the DomainContext object or even know how data is loaded behind the scenes: public class AdminViewModel : ViewModelBase { ServiceAgent _ServiceAgent = new ServiceAgent(); public AdminViewModel() { if (!DesignerProperties.IsInDesignTool) { LoadBooks(); } } private void LoadBooks() { _ServiceAgent.LoadBooks(LoadBooksCallback); } private void LoadBooksCallback(ObservableCollection<Book> books) { Books = books } } You could also handle the LoadBooksCallback method using a lambda if you wanted to minimize code just like I did earlier with the LoadBooks method in the ServiceAgent class. If you’re into Dependency Injection (DI), you could create an interface for the ServiceAgent type, reference it in the ViewModel and then inject in the object to use at runtime. There are certainly other techniques and strategies that can be used, but the code shown here provides an introductory look at the topic that should help get you started abstracting the DomainContext out of your ViewModel classes when using WCF RIA Services in Silverlight applications.

More SQL Smells

- by Nick Harrison

Let's continue exploring some of the SQL Smells from Phil's list. He has been putting together. Datatype mis-matches in predicates that rely on implicit conversion.(Plamen Ratchev) This is a great example poking holes in the whole theory of "If it works it's not broken" Queries will this probably will generally work and give the correct response. In fact, without careful analysis, you probably may be completely oblivious that there is even a problem. This subtle little problem will needlessly complicate queries and slow them down regardless of the indexes applied. Consider this example: CREATE TABLE [dbo].[Page]( [PageId] [int] IDENTITY(1,1) NOT NULL, [Title] [varchar](75) NOT NULL, [Sequence] [int] NOT NULL, [ThemeId] [int] NOT NULL, [CustomCss] [text] NOT NULL, [CustomScript] [text] NOT NULL, [PageGroupId] [int] NOT NULL; CREATE PROCEDURE PageSelectBySequence ( @sequenceMin smallint , @sequenceMax smallint ) AS BEGIN SELECT [PageId] , [Title] , [Sequence] , [ThemeId] , [CustomCss] , [CustomScript] , [PageGroupId] FROM [CMS].[dbo].[Page] WHERE Sequence BETWEEN @sequenceMin AND @SequenceMax END Note that the Sequence column is defined as int while the sequence parameter is defined as a small int. The problem is that the database may have to do a lot of type conversions to evaluate the query. In some cases, this may even negate the indexes that you have in place. Using Correlated subqueries instead of a join (Dave_Levy/ Plamen Ratchev) There are two main problems here. The first is a little subjective, since this is a non-standard way of expressing the query, it is harder to understand. The other problem is much more objective and potentially problematic. You are taking much of the control away from the optimizer. Written properly, such a query may well out perform a corresponding query written with traditional joins. More likely than not, performance will degrade. Whenever you assume that you know better than the optimizer, you will most likely be wrong. This is the fundmental problem with any hint. Consider a query like this: SELECT Page.Title , Page.Sequence , Page.ThemeId , Page.CustomCss , Page.CustomScript , PageEffectParams.Name , PageEffectParams.Value , ( SELECT EffectName FROM dbo.Effect WHERE EffectId = dbo.PageEffects.EffectId ) AS EffectName FROM Page INNER JOIN PageEffect ON Page.PageId = PageEffects.PageId INNER JOIN PageEffectParam ON PageEffects.PageEffectId = PageEffectParams.PageEffectId This can and should be written as: SELECT Page.Title , Page.Sequence , Page.ThemeId , Page.CustomCss , Page.CustomScript , PageEffectParams.Name , PageEffectParams.Value , EffectName FROM Page INNER JOIN PageEffect ON Page.PageId = PageEffects.PageId INNER JOIN PageEffectParam ON PageEffects.PageEffectId = PageEffectParams.PageEffectId INNER JOIN dbo.Effect ON dbo.Effects.EffectId = dbo.PageEffects.EffectId The correlated query may just as easily show up in the where clause. It's not a good idea in the select clause or the where clause. Few or No comments. This one is a bit more complicated and controversial. All comments are not created equal. Some comments are helpful and need to be included. Other comments are not necessary and may indicate a problem. I tend to follow the rule of thumb that comments that explain why are good. Comments that explain how are bad. Many people may be shocked to hear the idea of a bad comment, but hear me out. If a comment is needed to explain what is going on or how it works, the logic is too complex and needs to be simplified. Comments that explain why are good. Comments may explain why the sql is needed are good. Comments that explain where the sql is used are good. Comments that explain how tables are related should not be needed if the sql is well written. If they are needed, you need to consider reworking the sql or simplify your data model. Use of functions in a WHERE clause. (Anil Das) Calling a function in the where clause will often negate the indexing strategy. The function will be called for every record considered. This will often a force a full table scan on the tables affected. Calling a function will not guarantee that there is a full table scan, but there is a good chance that it will. If you find that you often need to write queries using a particular function, you may need to add a column to the table that has the function already applied.

- by Mysticgeek

There may be a time when you have an ISO image that you need to burn to a CD or DVD for use in a computer or other device. Today we show you how to do it using ImgBurn, ISO Recorder, and Windows Disc Image Burner in Windows 7. You might need to burn an ISO of an operating system, software app, CD, DVD…etc. It doesn’t matter what the ISO image is, burning an image is a fairly straight-forward process and here we’ll take a look at three free options to accomplish it. Using ImgBurn ImgBurn is an awesome free utility that will create ISO images, allow out burn almost anything, and a lot more. Although there are a lot advanced features available, burning an ISO to disc is easy. Download and install ImgBurn (link below) taking the defaults in the install wizard. The main thing to watch for and uncheck during installation is when it offers the worthless Ask Toolbar. The easiest way to use ImgBurn is to burn an image to disc is pop in a blank disc to the CD/DVD drive, right-click on the ISO file, and select Burn using ImgBurn. ImgBurn opens up with the source and destination fields already filled in. You can leave the default settings, then click the Write button. You’ll notice that the ImgBurn Log screen opens, this is by default and is meant to show error messages you may receive during the writing process. A successful burn! That is all there is to it…click Ok and close out of ImgBurn. Use ISO Recorder ISO Recorder (link below) is another great utility for burning ISO images to disc. They have a version for XP, Vista, and Windows 7 (32 & 64-bit Versions). Pop your blank disc into your CD/DVD drive and right-click on the ISO image file and select Copy image to CD from the Context Menu. In the next screen the image file path is in the Source Image file field. Under Recorder select the drive with your blank disc, select a recording speed and click Next. You’ll see a progress screen while the data is written to the disc and finalizing… That’s it! Your disc will pop out and you can click Finish to close out of ISO Recorder. Use Windows 7 If You’re using Windows 7, use the built in Windows Disc Image Burner feature to burn ISO images to disc. The process is very straight-forward, and for a full walkthrough on this, check out our article on how to burn an ISO image in Windows 7. Conclusion You don’t need an expensive commercial application to burn an ISO image to disc. Using any one of these free utilities will get the job done quite nicely.

Add Spell Checking to Your Favorite Windows Apps

- by Asian Angel

Some but not all Windows apps have built-in spell checking of some sort. If you want to add spell checking to all of your apps (or a select group) then join us as we look at tinySpell. Note: There is a paid version of this software (tinySpell+) available as well for those who want extra functionality. tinySpell in Action The installation process is simple and straightforward…as soon as you have finished installing tinySpell you will see your new “System Tray Icon”. You can see tinySpell’s “Context Menu” here. Before going any further you may want to have a look through the settings to make any desired display modifications. During our tests we found it very helpful to modify the Spelling Tip options…it will make for a much nicer and easier to read display when you have a spelling error. Clicking on the Applications… Command in the Context Menu will bring up the following window. You can really finesse how active tinySpell will be here: Create a special list of apps that tinySpell will not monitor Create a custom list of apps that tinySpell will monitor If you have any particular or unique words that you would like to add to tinySpell’s Dictionary ahead of time you can do that by clicking on the Dictionary… Command in the Context Menu. Want to check the spelling of a word ahead of time or find that you are just curious about how it is spelled? Click on Open spelling window in the Context Menu to access a special spell check window. For our example we misspelled “spelling” on purpose…notice that the word has turned red. Clicking on the Check Mark Button will open a drop-down list with suggested spellings for the word that you are inquiring about. Click on the appropriate listing if you intend to copy and paste the word. Next we moved on to Notepad. As we were typing tinySpell alerted us when we typed the word “app”. You will hear a small default system sound and see a small popup as shown here if tinySpell thinks a word has been misspelled. The System Tray Icon will also change to a yellow color. You can access the list of suggested spellings by either left clicking on the small popup or the System Tray Icon. If the word is a properly spelled “abbreviation” (or special/custom) like our word here you can select Add to dictionary. Going further in our text document we once again purposely misspelled “spelling”… Left clicking on the popup gave us access to the drop-down list of suggested spellings… And clicking on the correct spelling automatically inserted it into our document in place of the misspelled word. As you can see here tinySpell was even monitoring file names when we went to save the document. Very thorough indeed. Conclusion If your favorite app does not have built-in spell checking, then tinySpell will definitely be a welcome (and very helpful) addition to your Windows system. They offer a portable version as well so you can take it with you to any PC. Links Download tinySpell *Note: The download link is located approximately half-way down the page.

Note: The deafults for the product installation are used in this article. If your site uses alternative values then substitute those alternatives where applicable. Note: Examples shown in this article are examples for illustrative purposes only. When building a report in Oracle BI Publisher it may be necessary to call an XAI Inbound Service to get information via the object rather than directly calling the database tables for various reasons: The CLOB fields used in the Object are accessible for a report. Note: CLOB fields cannot be used as criteria in the current release. Objects can take advantage of algorithms to format or calculate additional data that is not stored in the database directly. For example, Information format strings can automatically generated by the object which gives consistent information between a report and the online screens. To use this facility the following process must be performed: Ensure that the product group, cisusers by default, is enabled for the SPLServiceBean in the console. This allows BI Publisher access to call Web Services directly. To ensure this follow the instructions below: Logon to the Oracle WebLogic server console using an appropriate administrator account. By default the user system or weblogic is provided for this purpose. Navigate to the Security Realms section and select your configured realm. This is set to myrealm by default. In the Roles and Policies section, expand the SPLService section of the Deployments option to reveal the SPLServiceBean roles. If there is no role associated with the SPLServiceBean, create a new EJB role and specify the cisusers role, by default. For example: Add a Role Condition to the role just created, with a Predicate List of Group and specify cisusers as the Group Argument Name. For example: Save all your changes. The XAI Inbound Services to be used by BI Publisher must be defined prior to using the interface. Refer to the XAI Best Practices (Doc Id: 942074.1) from My Oracle Support or via the online help for more information about this process. Inside BI Publisher create your report, according to the BI Publisher documentation. When specifying the dataset, under the Data Model Report option, specify the following to use an XAI Inbound Service as a data source: Parameter Comment Type Web Service Complex Type true Username Any valid user name within the product. This user MUST have security access to the objects referenced in the XAI Inbound Service Password Authentication password for Username Timeout Timeout, in seconds, set for the Web Service call. For example 60 seconds. WSDL URL Use the WSDL URL on the XAI Inbound Service definition as your WSDL URL. It will be in the following format by default:http://<host>:<port>/<server>/XAIApp/xaiserver/<service>?WSDLwhere: <host> - Host Name of Web Application Server <port> - Port allocated to Web Application Server for product access <server> - Server context for server <service> - XAI Inbound Service Name Note: For customers using secure transmission should substitute https instead of http and use the HTTPS port allocated to the product at installation time. Web Service Select the name of the service that shows in the drop-down menu. If no service name shows up, it means that Publisher could not establish a connection with the server or WSDL name provided in the above URL in order to get the service name. See BI Publisher server log for more information. Method Select the name of the Method that shows in the drop-down menu. A method name should show in the Method drop-down menu once the Web Service name is selected. For example: Additionally, filters can be used from the Web Service that can be generated, required or optional, from the WSDL in the Parameter List. For example:

OSB and Coherence Integration

- by mark.ms.smith

Anyone who has tried to manage Coherence nodes or tried to cache results in OSB, will appreciate the new functionality now available. As of WebLogic Server 10.3.4, you can use the WebLogic Administration Server, via the Administration Console or WLST, and java-based Node Manager to manage and monitor the life cycle of stand-alone Coherence cache servers. This is a great step forward as the previous options mainly involved writing your own scripts to do this. You can find an excellent description of how this works at James Bayer’s blog. You can also find the WebLogic documentation here.As of Oracle Service Bus 11gR1 (11.1.1.3.0), OSB now supports service result caching for Business Bervices with Coherence. If you use Business Services that return somewhat static results that do not change often, you can configure those Business Services to cache results. For Business Services that use result caching, you can control the time to live for the cached result. After the cached result expires, the next Business Service call results in invoking the back-end service to get the result. This result is then stored in the cache for future requests to access. I’m thinking that this caching functionality would be perfect for some sort of cross reference data that was refreshed nightly by batch. You can find the OSB Business Service documentation here.Result Caching in a dedicated JVMThis example demonstrates these new features by configuring a OSB Business Service to cache results in a separate Coherence JVM managed by WebLogic. The reason why you may want to use a separate, dedicated JVM is that the result cache data could potentially be quite large and you may want to protect your OSB java heap.In this example, the client will call an OSB Proxy Service to get Employee data based on an Employee Id. Using a Business Service, OSB calls an external system. The results are automatically cached and when called again, the respective results are retrieved from the cache rather than the external system.Step 1 – Set up your Coherence Server Via the OSB Administration Server Console, create your Coherence Server to be used as the results cache.Here are the configured Coherence Server arguments from the Server Start tab. Note that I’m using the default Cache Config and Override files in the domain.-Xms256m -Xmx512m -XX:PermSize=128m -XX:MaxPermSize=256m -Dtangosol.coherence.override=/app/middleware/jdev_11.1.1.4/user_projects/domains/osb_domain2/config/osb/coherence/osb-coherence-override.xml -Dtangosol.coherence.cluster=OSB-cluster -Dtangosol.coherence.cacheconfig=/app/middleware/jdev_11.1.1.4/user_projects/domains/osb_domain2/config/osb/coherence/osb-coherence-cache-config.xml -Dtangosol.coherence.distributed.localstorage=true -Dtangosol.coherence.management=all -Dtangosol.coherence.management.remote=true -Dcom.sun.management.jmxremote Just incase you need it, here is my Coherence Server classpath:/app/middleware/jdev_11.1.1.4/oracle_common/modules/oracle.coherence_3.6/coherence.jar: /app/middleware/jdev_11.1.1.4/modules/features/weblogic.server.modules.coherence.server_10.3.4.0.jar: /app/middleware/jdev_11.1.1.4/oracle_osb/lib/osb-coherence-client.jarBy default, OSB will try and create a local result cache instance. You need to disable this by adding the following JVM parameters to each of the OSB Managed Servers:-Dtangosol.coherence.distributed.localstorage=false -DOSB.coherence.cluster=OSB-clusterIf you need more information on configuring a remote result cache, have a look at the configuration documentration under the heading Using an Out-of-Process Coherence Cache Server.Step 2 – Configure your Business Service Under the respective Business Service Message Handling Configuration (Advanced Properties), you need to enable “Result Caching”. Additionally, you need to determine what the cache data will be keyed on. In the example below, I’m keying it on the unique Employee Id.The Results As this test was on my laptop, the actual timings are just an indication that there is a benefit to caching results. Using my test harness, I sent 10,000 requests to OSB, all with the same Employee Id. In this case, I had result caching disabled.You can see that this caused the back end Business Service (BS_GetEmployeeData) to be called for each request. Then after enabling result caching, I sent the same number of identical requests.You can now see the Business Service was only invoked once on the first request. All subsequent requests used the Results Cache.

Creating dynamic breadcrumb in asp.net mvc with mvcsitemap provider

- by Jalpesh P. Vadgama

I have done lots breadcrumb kind of things in normal asp.net web forms I was looking for same for asp.net mvc. After searching on internet I have found one great nuget package for mvpsite map provider which can be easily implemented via site map provider. So let’s check how its works. I have create a new MVC 3 web application called breadcrumb and now I am adding a reference of site map provider via nuget package like following. You can find more information about MVC sitemap provider on following URL. https://github.com/maartenba/MvcSiteMapProvid So once you add site map provider. You will find a Mvc.SiteMap file like following. And following is content of that file. <?xml version="1.0" encoding="utf-8" ?> <mvcSiteMap xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://mvcsitemap.codeplex.com/schemas/MvcSiteMap-File-3.0" xsi:schemaLocation="http://mvcsitemap.codeplex.com/schemas/MvcSiteMap-File-3.0 MvcSiteMapSchema.xsd" enableLocalization="true"> <mvcSiteMapNode title="Home" controller="Home" action="Index"> <mvcSiteMapNode title="About" controller="Home" action="About"/> </mvcSiteMapNode> </mvcSiteMap> So now we have added site map so now its time to make breadcrumb dynamic. So as we all know that with in the standard asp.net mvc template we have action link by default for Home and About like following. <div id="menucontainer"> <ul id="menu"> <li>@Html.ActionLink("Home", "Index", "Home")</li> <li>@Html.ActionLink("About", "About", "Home")</li> </ul> </div> Now I want to replace that with our sitemap provider and make it dynamic so I have added the following code. <div id="menucontainer"> @Html.MvcSiteMap().Menu(true) </div> That’s it. This is the magic code @Html.MvcSiteMap will dynamically create breadcrumb for you. Now let’s run this in browser. You can see that it has created breadcrumb dynamically without writing any action link code. So here you can see with MvcSiteMap provider we don’t have to write any code we just need to add menu syntax and rest it will do automatically. That’s it. Hope you liked it. Stay tuned for more till then happy programming.

Building vs. Buying a Master Data Management Solution

- by david.butler(at)oracle.com

Many organizations prefer to build their own MDM solutions. The argument is that they know their data quality issues and their data better than anyone. Plus a focused solution will cost less in the long run then a vendor supplied general purpose product. This is not unreasonable if you think of MDM as a point solution for a particular data quality problem. But this approach carries significant risk. We now know that organizations achieve significant competitive advantages when they deploy MDM as a strategic enterprise wide solution: with the most common best practice being to deploy a tactical MDM solution and grow it into a full information architecture. A build your own approach most certainly will not scale to a larger architecture unless it is done correctly with the larger solution in mind. It is possible to build a home grown point MDM solution in such a way that it will dovetail into broader MDM architectures. A very good place to start is to use the same basic technologies that Oracle uses to build its own MDM solutions. Start with the Oracle 11g database to create a flexible, extensible and open data model to hold the master data and all needed attributes. The Oracle database is the most flexible, highly available and scalable database system on the market. With its Real Application Clusters (RAC) it can even support the mixed OLTP and BI workloads that represent typical MDM data access profiles. Use Oracle Data Integration (ODI) for batch data movement between applications, MDM data stores, and the BI layer. Use Oracle Golden Gate for more real-time data movement. Use Oracle's SOA Suite for application integration with its: BPEL Process Manager to orchestrate MDM connections to business processes; Identity Management for managing users; WS Manager for managing web services; Business Intelligence Enterprise Edition for analytics; and JDeveloper for creating or extending the MDM management application. Oracle utilizes these technologies to build its MDM Hubs. Customers who build their own MDM solution using these components will easily migrate to Oracle provided MDM solutions when the home grown solution runs out of gas. But, even with a full stack of open flexible MDM technologies, creating a robust MDM application can be a daunting task. For example, a basic MDM solution will need: a set of data access methods that support master data as a service as well as direct real time access as well as batch loads and extracts; a data migration service for initial loads and periodic updates; a metadata management capability for items such as business entity matrixed relationships and hierarchies; a source system management capability to fully cross-reference business objects and to satisfy seemingly conflicting data ownership requirements; a data quality function that can find and eliminate duplicate data while insuring correct data attribute survivorship; a set of data quality functions that can manage structured and unstructured data; a data quality interface to assist with preventing new errors from entering the system even when data entry is outside the MDM application itself; a continuing data cleansing function to keep the data up to date; an internal triggering mechanism to create and deploy change information to all connected systems; a comprehensive role based data security system to control and monitor data access, update rights, and maintain change history; a flexible business rules engine for managing master data processes such as privacy and data movement; a user interface to support casual users and data stewards; a business intelligence structure to support profiling, compliance, and business performance indicators; and an analytical foundation for directly analyzing master data. Oracle's pre-built MDM Hub solutions are full-featured 3-tier Internet applications designed to participate in the full Oracle technology stack or to run independently in other open IT SOA environments. Building MDM solutions from scratch can take years. Oracle's pre-built MDM solutions can bring quality data to the enterprise in a matter of months. But if you must build, at lease build with the world's best technology stack in a way that simplifies the eventual upgrade to Oracle MDM and to the full enterprise wide information architecture that it enables.

How to install SharePoint Server 2013 Preview

- by ybbest

The Office 2013 and SharePoint Server 2013 Preview is announced yesterday and as a SharePoint Developer, I am really excited to learn all the new features and capabilities. Today I will show you how to install the preview. 1. Create a service account called SP2013Install and give this account Dbcreator and SecurityAdmin in SQL Server 2012 2. You need to run the following script to set the ‘maxdegree of parellism’ setting to the required value of 1 in SQL Server 2012(using sysadmin privilege) before configure the SharePoint Farm. Otherwise , you might get the error ‘This SQL Server Instance does not have the required maxdegree of parellism setting of 1’ sp_configure 'show advanced options', 1; GO RECONFIGURE WITH OVERRIDE; GO sp_configure 'max degree of parallelism', 1; GO RECONFIGURE WITH OVERRIDE; GO 3. Download the SharePoint preview from here and I am going to install it on Windows Server 2008R2 with SQL2012. 4. Click the Install software prerequisites, this works fine with the internet connection. (However, if you do not have internet connection, it is a bit tricky to install window azure AppFabric as it has to be installed using the prerequisite installer. Your computer might reboot a few times in the process.) 5.After the prerequisites are installed `completely, you can then install the Preview. Click the Install SharePoint Server and Enter the Product key you get from the Preview download page. 6. Accept the License terms and Click Next. 7. Leave the default path for the file location. 8. You can now start the installation process 9. After binary files are installed, you then can configure your farm using the farm configuration wizard. 10.Specify the Database server and the install account 11. Specify SharePoint farm passphrase. 12 Specify the port number , you should choose your own favorite port number. 13. Choose Create a New Server Farm and click next. 14. Double-check with the settings and click Next to Configure the farm install. 15. Finally, your farm is configured successfully and you now are able to go to your Central Admin site http://sp2010:6666/ 16. You should configure the services manually or automate using PowerShell (If you like to understand why,you can read the blog post here) ,however I will use the wizard to configure automatically here as this is a test machine. After the configuration is complete, you now be able to see your SharePoint Site. 17.To start the evaluate the Preview , you need to install Visual Studio 2012 RC , Microsoft Office Developer Tools for Visual Studio 2012,SharePoint 2013 Designer Preview , Office 2013 Preview.

Share Files and Folders and Internet between Guest OS and the Host in Hyper-V

- by Manesh Karunakaran

For those who are familiar with the VirtualPC, vmWare and VirtualBox environments will be quite irritated to find out that there is no direct way to share files from the Host machine to the Virtualized guest environment. This is a good thing from a CIO perspective because there’s excellent isolation for the virtualized environments this way, but for the developer junkies like us, this is an irritant, especially for those who have nuked their Windows 7 OS and installed Windows Server 2008 R2 for all the the SharePoint friendliness that it offers. Here’s a quick 5 minutes howto on Enabling Shared Folders and Internet Access for the Hyper-V images, for those who are still struggling with this. Step 1: Add a Virtual Network Adapter to your Guest OS For this, shut down the guest machine, go to its settings and add a Virtual Network Adapter as given in the images below Step 2: Enable Virtual Networking in Hyper-V Setting this up is very easy. In the Hyper-V Manager, under Actions (right panel), click the Virtual Network Manager. In the Virtual Network Manager in the Create virtual network panel, select Internal and click the Add button. At this point if you open Control Panel\Network and Internet\Network Connections you will be able to see the new Network Adapter, Now name it to something meaningful other than Network Adapter X. Now you can add this network to each of your virtual machines, but at this point, unless you assign an IP address in each connection, you won't be able to do much. Step 3: Enable Internet Connection Sharing so that Guest OS’es also can connect to the internet. To enable ICS follow these steps: Click on the network icon in the tray of your host machine and select Network and Sharing Center. From there click Manage network connections. Select the network adapter that you use to access the Internet. Right click it and select Properties. In the properties dialog select the Sharing tab. On this tab check the box that says "Allow other network users..." and then set the Home networking connection to be the network adapter that was created above (now you see why I said to rename it to something useful). Now your virtual machines that have this network connection will automatically get an IP address and will be able to connect to the Internet (provided your internet connection is working). Because each adapter also gets an automatic address you can now share files and folders between your host and your virtual machines which is important since you can't just drag-and-drop files like you can with Virtual PC. Step 4: Create a Shared Folder in the Host Machine and use it in the Guest machine. Right click on the folder that you want to Share and select ‘Share with\Specific People’ and specify who all can access the share. Open the Guest OS from Hyper V Navigate to Start > Run and type in the Address of the Share (Or Map a Drive to the Share) Bingo! The Share opens!! :) Now you can share as many files and folders as you want between the host and the guest, and you also have internet access inside the Virtual machines. Hope that helps.

MVC 2 jQuery Client-side Validation

- by nmarun

Well, I watched Phil Haack’s show What's New in Microsoft ASP.NET MVC 2 and was impressed about the client-side validation (starts at 17:45) that MVC 2 offers. I tried creating the same, but Phil does not show what .js files need to be included and also I was not able to find the source code for the application that he used. In order to find out the required JavaScript file references, I added all of the files in my application to the page and ran it. Of course it worked, but this is definitely not an optimum solution. By removing one at a time and testing the app, I’ve short-listed the following ones: 1: <script src="../../Scripts/jquery-1.4.1.min.js" type="text/javascript"></script 2: <script src="../../Scripts/MicrosoftAjax.js" type="text/javascript"></script> 3: <script src="../../Scripts/MicrosoftMvcValidation.js" type="text/javascript"></script> Now, a little about the feature itself. Say, I’m working with a Book application so my model will look something like: 1: public class Book 2: { 3: [HiddenInput(DisplayValue = false)] 4: public int BookId { get; set; } 5: 6: [DisplayName("Book Title")] 7: [Required(ErrorMessage = "Book title is required")] 8: [StringLength(20, ErrorMessage = "Must be under 20 characters")] 9: public string Title { get; set; } 10: 11: [Required(ErrorMessage = "Author is required")] 12: [StringLength(40, ErrorMessage = "Must be under 40 characters")] 13: public string Author { get; set; } 14: 15: public decimal Price { get; set; } 16: 17: [DisplayName("ISBN")] 18: [StringLength(13, ErrorMessage = "Must be 13 characters")] 19: public string Isbn { get; set; } 20: } This ensures that the data passed will be validated upon post. But what would happen if you add the line (along with the above mentioned .js files): 1: <% Html.EnableClientValidation(); %> Now, this acts as ‘on-the-fly’ or ‘real-time’ validation. Now, when the user types 20 characters for the Title, the error shows up right on the 21st character. Beautiful… and you do not have to create the JavaScript function(s) for this. They’re auto-magically created for you. (Doing a ‘View Source’ on the browser page shows you the JavaScript logic that goes on behind the scenes). I bumped into another post that shows how .net 4 allows us to create custom validation attributes: Dynamic Range validation in MVC 2. This will help us attach virtually any business logic to the model itself. Please see the source code I’ve worked with.

SQL SERVER – Solution of Puzzle – Swap Value of Column Without Case Statement

- by pinaldave

Earlier this week I asked a question where I asked how to Swap Values of the column without using CASE Statement. Read here: SQL SERVER – A Puzzle – Swap Value of Column Without Case Statement. I have proposed 3 different solutions in the blog posts itself. I had requested the help of the community to come up with alternate solutions and honestly I am stunned and amazed by the qualified entries. I will be not able to cover every single solution which is posted as a comment, however, I would like to for sure cover few interesting entries. However, I am selecting 5 solutions which are different (not necessary they are most optimal or best – just different and interesting). Just for clarity I am involving the original problem statement here. USE tempdb GO CREATE TABLE SimpleTable (ID INT, Gender VARCHAR(10)) GO INSERT INTO SimpleTable (ID, Gender) SELECT 1, 'female' UNION ALL SELECT 2, 'male' UNION ALL SELECT 3, 'male' GO SELECT * FROM SimpleTable GO -- Insert Your Solutions here -- Swap value of Column Gender SELECT * FROM SimpleTable GO DROP TABLE SimpleTable GO Here are the five most interesting and different solutions I have received. Solution by Roji P Thomas UPDATE S SET S.Gender = D.Gender FROM SimpleTable S INNER JOIN SimpleTable D ON S.Gender != D.Gender I really loved the solutions as it is very simple and drives the point home – elegant and will work pretty much for any values (not necessarily restricted by the option in original question ‘male’ or ‘female’). Solution by Aneel CREATE TABLE #temp(id INT, datacolumn CHAR(4)) INSERT INTO #temp VALUES(1,'gent'),(2,'lady'),(3,'lady') DECLARE @value1 CHAR(4), @value2 CHAR(4) SET @value1 = 'lady' SET @value2 = 'gent' UPDATE #temp SET datacolumn = REPLACE(@value1 + @value2,datacolumn,'') Aneel has very interesting solution where he combined both the values and replace the original value. I personally liked this creativity of the solution. Solution by SIJIN KUMAR V P UPDATE SimpleTable SET Gender = RIGHT(('fe'+Gender), DIFFERENCE((Gender),SOUNDEX(Gender))*2) Sijin has amazed me with Difference and Soundex function. I have never visualized that above two functions can resolve the problem. Hats off to you Sijin. Solution by Nikhildas UPDATE St SET St.Gender = t.Gender FROM SimpleTable St CROSS Apply (SELECT DISTINCT gender FROM SimpleTable WHERE St.Gender != Gender) t I was expecting that someone will come up with this solution where they use CROSS APPLY. This is indeed very neat and for sure interesting exercise. If you do not know how CROSS APPLY works this is the time to learn. Solution by mistermagooo UPDATE SimpleTable SET Gender=X.NewGender FROM (VALUES('male','female'),('female','male')) AS X(OldGender,NewGender) WHERE SimpleTable.Gender=X.OldGender As per author this is a slow solution but I love how syntaxes are placed and used here. I love how he used syntax here. I will say this is the most beautifully written solution (not necessarily it is best). Bonus: Solution by Madhivanan Somehow I was confident Madhi – SQL Server MVP will come up with something which I will be compelled to read. He has written a complete blog post on this subject and I encourage all of you to go ahead and read it. Now personally I wanted to list every single comment here. There are some so good that I am just amazed with the creativity. I will write a part of this blog post in future. However, here is the challenge for you. Challenge: Go over 50+ various solutions listed to the simple problem here. Here are my two asks for you. 1) Pick your best solution and list here in the comment. This exercise will for sure teach us one or two things. 2) Write your own solution which is yet not covered already listed 50 solutions. I am confident that there is no end to creativity.

SQL SERVER – Fix: Error : 402 The data types ntext and varchar are incompatible in the equal to operator

- by pinaldave

Some errors are very simple to understand but the solution of the same is not easy to figure out. Here is one of the similar errors where it clearly suggests where the problem is but does not tell what is the solution. Additionally, there are multiple solutions so developers often get confused with which one is correct and which one is not correct. Let us first recreate scenario and understand where the problem is. Let us run following USE Tempdb GO CREATE TABLE TestTable (ID INT, MyText NTEXT) GO SELECT ID, MyText FROM TestTable WHERE MyText = 'AnyText' GO DROP TABLE TestTable GO When you run above script it will give you following error. Msg 402, Level 16, State 1, Line 1 The data types ntext and varchar are incompatible in the equal to operator. One of the questions I often receive is that voucher is for sure compatible to equal to operator, then why does this error show up. Well, the answer is much simpler I think we have not understood the error message properly. Please see the image below. The next and varchar are not compatible when compared with each other using equal sign. Now let us change the data type on the right side of the string to nvarchar from varchar. To do that we will put N’ before the string. USE Tempdb GO CREATE TABLE TestTable (ID INT, MyText NTEXT) GO SELECT ID, MyText FROM TestTable WHERE MyText = N'AnyText' GO DROP TABLE TestTable GO When you run above script it will give following error. Msg 402, Level 16, State 1, Line 1 The data types ntext and nvarchar are incompatible in the equal to operator. You can see that error message also suggests that now we are comparing next to nvarchar. Now as we have understood the error properly, let us see various solutions to the above problem. Solution 1: Convert the data types to match with each other using CONVERT function. Change the datatype of the MyText to nvarchar. SELECT ID, MyText FROM TestTable WHERE CONVERT(NVARCHAR(MAX), MyText) = N'AnyText' GO Solution 2: Convert the data type of columns from NTEXT to NVARCHAR(MAX) (TEXT to VARCHAR(MAX) ALTER TABLE TestTable ALTER COLUMN MyText NVARCHAR(MAX) GO Now you can run the original query again and it will work fine. Solution 3: Using LIKE command instead of Equal to command. SELECT ID, MyText FROM TestTable WHERE MyText LIKE 'AnyText' GO Well, any of the three of the solutions will work. Here is my suggestion if you can change the column data type from ntext or text to nvarchar or varchar, you should follow that path as text and ntext datatypes are marked as deprecated. All developers any way to change the deprecated data types in future, it will be a good idea to change them right early. If due to any reason you can not convert the original column use Solution 1 for temporary fix. Solution 3 is the not the best solution and use it as a last option. Did I miss any other method? If yes, please let me know and I will add the solution to original blog post with due credit.

Avoiding new operator in JavaScript -- the better way

- by greengit

Warning: This is a long post. Let's keep it simple. I want to avoid having to prefix the new operator every time I call a constructor in JavaScript. This is because I tend to forget it, and my code screws up badly. The simple way around this is this... function Make(x) { if ( !(this instanceof arguments.callee) ) return new arguments.callee(x); // do your stuff... } But, I need this to accept variable no. of arguments, like this... m1 = Make(); m2 = Make(1,2,3); m3 = Make('apple', 'banana'); The first immediate solution seems to be the 'apply' method like this... function Make() { if ( !(this instanceof arguments.callee) ) return new arguments.callee.apply(null, arguments); // do your stuff } This is WRONG however -- the new object is passed to the apply method and NOT to our constructor arguments.callee. Now, I've come up with three solutions. My simple question is: which one seems best. Or, if you have a better method, tell it. First – use eval() to dynamically create JavaScript code that calls the constructor. function Make(/* ... */) { if ( !(this instanceof arguments.callee) ) { // collect all the arguments var arr = []; for ( var i = 0; arguments[i]; i++ ) arr.push( 'arguments[' + i + ']' ); // create code var code = 'new arguments.callee(' + arr.join(',') + ');'; // call it return eval( code ); } // do your stuff with variable arguments... } Second – Every object has __proto__ property which is a 'secret' link to its prototype object. Fortunately this property is writable. function Make(/* ... */) { var obj = {}; // do your stuff on 'obj' just like you'd do on 'this' // use the variable arguments here // now do the __proto__ magic // by 'mutating' obj to make it a different object obj.__proto__ = arguments.callee.prototype; // must return obj return obj; } Third – This is something similar to second solution. function Make(/* ... */) { // we'll set '_construct' outside var obj = new arguments.callee._construct(); // now do your stuff on 'obj' just like you'd do on 'this' // use the variable arguments here // you have to return obj return obj; } // now first set the _construct property to an empty function Make._construct = function() {}; // and then mutate the prototype of _construct Make._construct.prototype = Make.prototype; eval solution seems clumsy and comes with all the problems of "evil eval". __proto__ solution is non-standard and the "Great Browser of mIsERY" doesn't honor it. The third solution seems overly complicated. But with all the above three solutions, we can do something like this, that we can't otherwise... m1 = Make(); m2 = Make(1,2,3); m3 = Make('apple', 'banana'); m1 instanceof Make; // true m2 instanceof Make; // true m3 instanceof Make; // true Make.prototype.fire = function() { // ... }; m1.fire(); m2.fire(); m3.fire(); So effectively the above solutions give us "true" constructors that accept variable no. of arguments and don't require new. What's your take on this. -- UPDATE -- Some have said "just throw an error". My response is: we are doing a heavy app with 10+ constructors and I think it'd be far more wieldy if every constructor could "smartly" handle that mistake without throwing error messages on the console.

SQLAuthority News – Follow up on – Replace a Column Name in Multiple Stored Procedure all together

- by pinaldave

Last month I had a fantastic time with lots of puzzles and brain teasers, the amount of participation which I have received on the blog is indeed inspiring to write more. One of the blog post was about how to replace a column name in all the stored procedures. The article had very interesting conversation as a follow up. Please read the original article Replace a Column Name in Multiple Stored Procedure all together before reading this blog further as they are connected. Let us start few of the interesting comments. SQL Server Expert Imran Mohammed had a wonderful first and excellent note. I suggest all of you to read it. Imran stresses on the Data Modelling and Logical as well as Physical Design. Developers must create a logical design and get approval on naming convention, data types, references, constraints, indexes etc. He further suggested that one should not cut steps but must follow all the industry standards and guidelines. Here extended my blog post with following note – “Extending Pinal’s answer, what you can do is go to database properties, all tasks, scripts objects, in scripting wizard select all the stored procedure for which you want to change column name, export the query to a new window and then do find and replace, all in once window and execute the script. But make sure you check what you are replacing, sometimes column names are also used in table names, for ex:Table Name: Product and Column Name: ProductId, ProductName”. Thanks Imran Great Points! Gatej Alexandru suggested that it is not good idea to DROP or CREATE but rather use ALTER as quite possible there may be permissions issue as well. Very good point let me see if I can write blog post over it. Vinay Kumar and SQLStudent144 have proposed another method to achieve the same. I am combining their solution and writing them here. Step 1. Press Ctrl+T or change “Result to Text” mode. Step 2. Execute below commands.SELECT 'EXEC sp_helptext [' + referencing_schema_name + '.' + referencing_entity_name + ']' FROM sys.dm_sql_referencing_entities('schema.objectname','OBJECT') Where schema.objectname is the object or table you are searching for. Step 3. Now copy the result and paste in new window. Again Press Ctrl+T or change “Result to Text” mode. Step 4. Copy the result and paste in new window. Execute the query. Step 5. Copy the result and paste in new window. Step 6. Now find your searching text in the script, make necessary changes and execute this script. Do not forget to remove the code which is generated in resultset which are not relevant to the T-SQL Script. Digitqr suggest we can do this for other objects besides Stored Procedure as well. Iosif suggests to use tool SQL Search from RedGate. I guess this sums it well. We have an alternative perspective to our original issue of replacing the column name in multiple stored procedure.

Preview Before You Paste with Live Preview in Office 2010

- by DigitalGeekery

Do you often find yourself frustrated that content you just copied and pasted didn’t turn out the way you expected? With the new Live Preview in Office 2010, you can preview how copied content will look when it’s pasted even between Office applications. Not every paste preview option will be available in every circumstance. The available options will be based on the applications being used and what content is copied. Copy your content like normal by right-clicking and selecting Copy, pressing Crtl + C, or selecting Copy from the Home tab. Next, select your location to paste the content. Now you can access the Paste Preview buttons either by selecting the Paste dropdown list from the Home tab… …Or by right-clicking. As you hover your cursor over each of the Paste Options buttons, you will see a preview of what it will look like if you paste using that option. Click the corresponding button when you find the paste option you like. The “Paste” will paste all the content and formatting as you can see below. Values will paste values only, no formatting. Formatting will paste only the formatting, no values. Hover over Paste Special to reveal any additional paste options. The process is similar in other Office applications. As you can see in the Word document below, Keep Text Only will paste the text, but not the orange color format from the original text. Even after you’ve pasted, there is still time to change your mind. After you paste content you’ll see a Paste Option button near your content. If you don’t, you can pull it up by pressing the Ctrl key. Note: This is also available after using Ctrl + V to paste. Click to enable the dropdown and select one of the available options. Using Live Paste Preview between multiple applications is just as easy. If we preview pasting the content from our Word document into PowerPoint by using the Keep Source Formatting option, we’ll see that the outcome looks awful. Selecting the Use Destination Theme will merge the text into the theme of the PowerPoint document and looks a lot better on our slide. Live Paste Preview is a nice addition to Office 2010 and is sure to save time spent undoing the unexpected consequences of pasting content. Looking for more Office 2010 tips? Check out some of our other Office 2010 posts like how to create a customized tab on the Office 2010 ribbon, and how to use the streamlined printing features in Office 2010.

Install Oracle Configuration Manager's Standalone Collector

- by Get Proactive Customer Adoption Team

Untitled Document The Why and the How If you have heard of Oracle Configuration Manager (OCM), but haven’t installed it, I’m guessing this is for one of two reasons. Either you don’t know how it helps you or you don’t know how to install it. I’ll address both of those reasons today. First, let’s take a quick look at how My Oracle Support and the Oracle Configuration Manager work together to gain a good understanding of what their differences and roles are before we tackle the install. Oracle Configuration Manger is the tool that actually performs the data collection task. You deploy this lightweight piece of software into your system to collect configuration information about the system and OCM uploads that data to Oracle’s customer configuration repository. Oracle Support Engineers then have the configuration data available when you file a service request. You can also view the data through My Oracle Support. The real value is that the data Oracle Configuration Manager collects can help you avoid problems and get your Service Requests solved more quickly. When you view the information in My Oracle Support’s user interface to OCM, it may help you avoid situations that create problems. The proactive tools included in Oracle Configuration Manager help you avoid issues before they occur. You also save time because you didn’t need to open a service request. For example, you can use this capability when you need to compare your system configuration at two points in time, or monitor the system health. If you make the configuration data available to Oracle Support Engineers, when you need to open a Service Request the data helps them diagnose and resolve your critical system issues more quickly, which means you get answers more quickly too. Quick Installation Process Overview Before we dive into the step-by-step details, let me provide a quick overview. For some of you, this will be all you need. Log in to My Oracle Support and download the data collector from Collector tab. If you don’t see the Collector tab, click the More tab gain access. On the Collector tab, you will find a drop-down list showing which platforms are available. You can also see more ways to the Collector can help you if you click through the carousel of benefits. After you download the software for your platform, use FTP to move that file (.zip) from your PC to the server that hosts the Oracle software. Once you have that file on the server, locate the $ORACLE_HOME directory, and unzip the file within that directory. You can then use the command line tool to start the installation process. The installation process requires the My Oracle Support credential (Support Identifier, username, and password) Proxy specification (Host IP Address, Port number, username and password) Installation Step-by-Step Download the collector zip file from My Oracle Support and place it into your $Oracle_Home Unzip the zip file you downloaded from My Oracle Support – this will create a directory named CCR with several subdirectories Using the command line go to “$ORACLE_HOME/CCR/bin” and run the following command “setupCCR” Provide your My Oracle Support credential: login, password, and Support Identifier The installer will start deploying the collector application You have installed the Collector Post Installation Now that you have installed successfully, the scheduler is ready to collect configuration information for the software available in your Oracle Home. By default, the first collection will take place the day after the installation. If you want to run an instrumentation script to start the configuration collection of your Oracle Database server, E-Business Suite, or Enterprise Manager, you will find more details on that in the Installation and Administration Guide for My Oracle Support Configuration Manager.

SQL SERVER – Installing SQL Server Data Tools and SSRS

- by Pinal Dave

This example is from the Beginning SSRS by Kathi Kellenberger. Supporting files are available with a free download from the www.Joes2Pros.com web site. If you have installed SQL Server, but are missing the Data Tools or Reporting Services Double-click the SQL Server 2012 installation media. Click the Installation link on the left to view the Installation options. Click the top link New SQL Server stand-alone installation or add features to an existing installation. Follow the SQL Server Setup wizard until you get to the Installation Type screen. At that screen, select Add features to an existing instance of SQL Server 2012. Click Next to move to the Feature Selection page. Select Reporting Services – Native and SQL Server Data Tools. If the Management Tools have not been installed, go ahead and choose them as well. Continue through the wizard and reboot the computer at the end of the installation if instructed to do so. Configure Reporting Services If you installed Reporting Services during the installation of the SQL Server instance, SSRS will be configured automatically for you. If you install SSRS later, then you will have to go back and configure it as a subsequent step. Click Start > All Programs > Microsoft SQL Server 2012 > Configuration Tools > Reporting Services Configuration Manager > Connect on the Reporting Services Configuration Connection dialog box. On the left-hand side of the Reporting Services Configuration Manager, click Database. Click the Change Database button on the right side of the screen. Select Create a new report server database and click Next. Click through the rest of the wizard accepting the defaults. This wizard creates two databases: ReportServer, used to store report definitions and security, and ReportServerTempDB which is used as scratch space when preparing reports for user requests. Now click Web Service URL on the left-hand side of the Reporting Services Configuration Manager. Click the Apply button to accept the defaults. If the Apply button has been grayed out, move on to the next step. This step sets up the SSRS web service. The web service is the program that runs in the background that communicates between the web page, which you will set up next, and the databases. The final configuration step is to select the Report Manager URL link on the left. Accept the default settings and click Apply. If the Apply button was already grayed out, this means the SSRS was already configured. This step sets up the Report Manager web site where you will publish reports. You may be wondering if you also must install a web server on your computer. SQL Server does not require that the Internet Information Server (IIS), the Microsoft web server, be installed to run Report Manager. Click Exit to dismiss the Reporting Services Configuration Manager dialog box. Tomorrow’s Post Tomorrow’s blog post will show how to create your first report using the Report Wizard. If you want to learn SSRS in easy to simple words – I strongly recommend you to get Beginning SSRS book from Joes 2 Pros.

concurrency::accelerator_view

- by Daniel Moth

Overview We saw previously that accelerator represents a target for our C++ AMP computation or memory allocation and that there is a notion of a default accelerator. We ended that post by introducing how one can obtain accelerator_view objects from an accelerator object through the accelerator class's default_view property and the create_view method. The accelerator_view objects can be thought of as handles to an accelerator. You can also construct an accelerator_view given another accelerator_view (through the copy constructor or the assignment operator overload). Speaking of operator overloading, you can also compare (for equality and inequality) two accelerator_view objects between them to determine if they refer to the same underlying accelerator. We'll see later that when we use concurrency::array objects, the allocation of data takes place on an accelerator at array construction time, so there is a constructor overload that accepts an accelerator_view object. We'll also see later that a new concurrency::parallel_for_each function overload can take an accelerator_view object, so it knows on what target to execute the computation (represented by a lambda that the parallel_for_each also accepts). Beyond normal usage, accelerator_view is a quality of service concept that offers isolation to multiple "consumers" of an accelerator. If in your code you are accessing the accelerator from multiple threads (or, in general, from different parts of your app), then you'll want to create separate accelerator_view objects for each thread. flush, wait, and queuing_mode When you create an accelerator_view via the create_view method of the accelerator, you pass in an option of immediate or deferred, which are the two members of the queuing_mode enum. At any point you can access this value from the queuing_mode property of the accelerator_view. When the queuing_mode value is immediate (which is the default), any commands sent to the device such as kernel invocations and data transfers (e.g. parallel_for_each and copy, as we'll see in future posts), will get submitted as soon as the runtime sees fit (that is the definition of immediate). When the value of queuing_mode is deferred, the commands will be batched up. To send all buffered commands to the device for execution, there is a non-blocking flush method that you can call. If you wish to block until all the commands have been sent, there is a wait method you can call. Deferring is a more advanced scenario aimed at performance gains when you are submitting many device commands and you want to avoid the tiny overhead of flushing/submitting each command separately. Querying information Just like accelerator, accelerator_view exposes the is_debug and version properties. In fact, you can always access the accelerator object from the accelerator property on the accelerator_view class to access the accelerator interface we looked at previously. Interop with D3D (aka DX) In a later post I'll show an example of an app that uses C++ AMP to compute data that is used in pixel shaders. In those scenarios, you can benefit by integrating C++ AMP into your graphics pipeline and one of the building blocks for that is being able to use the same device context from both the compute kernel and the other shaders. You can do that by going from accelerator_view to device context (and vice versa), through part of our interop API in amp.h: *get_device, create_accelerator_view. More on those in a later post. Comments about this post by Daniel Moth welcome at the original blog.

glsl shader to allow color change of skydome ogre3d

- by Tim

I'm still very new to all this but learning a lot. I'm putting together an application using Ogre3d as the rendering engine. So far I've got it running, with a simple scene, a day/night cycle system which is working okay. I'm now moving on to looking at changing the color of the skydome material based on the time of day. What I've done so far is to create a struct to hold the ColourValues for the different aspects of the scene. struct todColors { Ogre::ColourValue sky; Ogre::ColourValue ambient; Ogre::ColourValue sun; }; I created an array to store all the colours todColors sceneColours [4]; I populated the array with the colours I want to use for the various times of the day. For instance DayTime (when the sun is high in the sky) sceneColours[2].sky = Ogre::ColourValue(135/255, 206/255, 235/255, 255); sceneColours[2].ambient = Ogre::ColourValue(135/255, 206/255, 235/255, 255); sceneColours[2].sun = Ogre::ColourValue(135/255, 206/255, 235/255, 255); I've got code to work out the time of the day using a float currentHours to store the current hour of the day 10.5 = 10:30 am. This updates constantly and updates the sun as required. I am then calculating the appropriate colours for the time of day when relevant using else if( currentHour >= 4 && currentHour < 7) { // Lerp from night to morning Ogre::ColourValue lerp = Ogre::Math::lerp<Ogre::ColourValue, float>(sceneColours[GT_TOD_NIGHT].sky , sceneColours[GT_TOD_MORNING].sky, (currentHour - 4) / (7 - 4)); } My original attempt to get this to work was to dynamically generate a material with the new colour and apply that material to the skydome. This, as you can probably guess... didn't go well. I know it's possible to use shaders where you can pass information such as colour to the shader from the code but I am unsure if there is an existing simple shader to change a colour like this or if I need to create one. What is involved in creating a shader and material definition that would allow me to change the colour of a material without the overheads of dynamically generating materials all the time? EDIT : I've created a glsl vertex and fragment shaders as follows. Vertex uniform vec4 newColor; void main() { gl_FrontColor = newColor; gl_Position = ftransform(); } Fragment void main() { gl_FragColor = gl_Color; } I can pass a colour to it using ShaderDesigner and it seems to work. I now need to investigate how to use it within Ogre as a material. EDIT : I created a material file like this : vertex_program colour_vs_test glsl { source test.vert default_params { param_named newColor float4 0.0 0.0 0.0 1 } } fragment_program colour_fs_glsl glsl { source test.frag } material Test/SkyColor { technique { pass { lighting off fragment_program_ref colour_fs_glsl { } vertex_program_ref colour_vs_test { } } } } In the code I have tried : Ogre::MaterialPtr material = Ogre::MaterialManager::getSingleton().getByName("Test/SkyColor"); Ogre::GpuProgramParametersSharedPtr params = material->getTechnique(0)->getPass(0)->getVertexProgramParameters(); params->setNamedConstant("newcolor", Ogre::Vector4(0.7, 0.5, 0.3, 1)); I've set that as the Skydome material which seems to work initially. I am doing the same with the code that is attempting to lerp between colours, but when I include it there, it all goes black. Seems like there is now a problem with my colour lerping.
