  • A Look at the GridView's New Sorting Styles in ASP.NET 4.0

    Like every Web control in the ASP.NET toolbox, the GridView includes a variety of style-related properties, including CssClass, Font, ForeColor, BackColor, Width, Height, and so on. The GridView also includes style properties that apply to certain classes of rows in the grid, such as RowStyle, AlternatingRowStyle, HeaderStyle, and PagerStyle. Each of these meta-style properties offer the standard style properties (CssClass, Font, etc.) as subproperties. In ASP.NET 4.0, Microsoft added four new style properties to the GridView control: SortedAscendingHeaderStyle, SortedAscendingCellStyle, SortedDescendingHeaderStyle, and SortedDescendingCellStyle. These four properties are meta-style properties like RowStyle and HeaderStyle, but apply to column of cells rather than a row. These properties only apply when the GridView is sorted - if the grid's data is sorted in ascending order then the SortedAscendingHeaderStyle and SortedAscendingCellStyle properties define the styles for the column the data is sorted by. The SortedDescendingHeaderStyle and SortedDescendingCellStyle properties apply to the sorted column when the results are sorted in descending order. These four new properties make it easier to customize the appearance of the column by which the data is sorted. Using these properties along with a touch of Cascading Style Sheets (CSS) it is possible to add up and down arrows to the sorted column's header to indicate whether the data is sorted in ascending or descending order. Likewise, these properties can be used to shade the sorted column or make its text bold. This article shows how to use these four new properties to style the sorted column. Read on to learn more!

  • Experience your music in a whole new way with Zune for PC

    - by Matthew Guay
    Tired of the standard Media Player look and feel, and want something new and innovative?  Zune offers a fresh, new way to enjoy your music, videos, pictures, and podcasts, whether or not you own a Zune device. Microsoft started out on a new multimedia experience for PCs and mobile devices with the launch of the Zune several years ago.  The Zune devices have been well received and noted for their innovative UI, and the Zune HD’s fluid interface is the foundation for the widely anticipated Windows Phone 7.  But regardless of whether or not you have a Zune Device, you can still use the exciting new UI and services directly from your PC.  Zune for Windows is a very nice media player that offers a music and video store and wide support for multimedia formats including those used in Apple products.  And if you enjoy listening to a wide variety of music, it also offers the Zune Pass which lets you stream an unlimited number of songs to your computer and download 10 songs for keeps per month for $14.99/month. Or you can do a pre-paid music card as well.  It does all this using the new Metro UI which beautifully shows information using text in a whole new way.  Here’s a quick look at setting up and using Zune on your PC. Getting Started Download the installer (link below), and run it to begin setup.  Please note that Zune offers a separate version for computers running the 64 bit version of Windows Vista or 7, so choose it if your computer is running these. Once your download is finished, run the installer to setup Zune on your computer.  Accept the EULA when prompted. If there are any updates available, they will automatically download and install during the setup.  So, if you’re installing Zune from a disk (for example, one packaged with a Zune device), you don’t have to worry if you have the latest version.  Zune will proceed to install on your computer.   It may prompt you to restart your computer after installation; click Restart Now so you can proceed with your Zune setup.  The reboot appears to be for Zune device support, and the program ran fine otherwise without rebooting, so you could possibly skip this step if you’re not using a Zune device.  However, to be on the safe side, go ahead and reboot. After rebooting, launch Zune.  It will play a cute introduction video on first launch; press skip if you don’t want to watch it. Zune will now ask you if you want to keep the default settings or change them.  Choose Start to keep the defaults, or Settings to customize to your wishes.  Do note that the default settings will set Zune as your default media player, so click Settings if you wish to change this. If you choose to change the default settings, you can change how Zune finds and stores media on your computer.  In Windows 7, Zune will by default use your Windows 7 Libraries to manage your media, and will in fact add a new Podcasts library to Windows 7. If your media is stored on another location, such as on a server, then you can add this to the Library.  Please note that this adds the location to your system-wide library, not just the Zune player. There’s one last step.  Enter three of your favorite artists, and Zune will add Smart DJ mixes to your Quickplay list based on these.  Some less famous or popular artists may not be recognized, so you may have to try another if your choice isn’t available.  Or, you can click Skip if you don’t want to do this right now. Welcome to Zune!  This is the default first page, QuickPlay, where you can easily access your pinned and new items.   If you have a Zune account, or would like to create a new one, click Sign In on the top. Creating a new account is quick and simple, and if you’re new to Zune, you can try out a 14 day trial of Zune Pass for free if you want. Zune allows you to share your listening habits and favorites with friends or the world, but you can turn this off or change it if you like. Using Zune for Windows To access your media, click the Collection link on the top left.  Zune will show all the media you already have stored on your computer, organized by artist and album. Right-click on any album, and you choose to have Zune find album art or do a variety of other tasks with the media.   When playing media, you can view it in several unique ways.  First, the default Mix view will show related tracks to the music you’re playing from Smart DJ.  You can either play these fully if you’re a Zune Pass subscriber, or otherwise you can play 30 second previews. Then, for many popular artists, Zune will change the player background to show pictures and information in a unique way while the music is playing.  The information may range from history about the artist to the popularity of the song being played.   Zune also works as a nice viewer for the pictures on your computer. Start a slideshow, and Zune will play your pictures with nice transition effects and music from your library. Zune Store The Zune Store offers a wide variety of music, TV shows, and videos for purchase.  If you’re a Zune Pass subscriber, you can listen to or download any song without purchasing it; otherwise, you can preview a 30 second clip first. Zune also offers a wide selection of Podcasts you can subscribe to for free. Using Zune for PC with a Zune Device If you have a Zune device attached to your computer, you can easily add media files to it by simply dragging them to the Zune device icon in the left corner.  In the future, this will also work with Windows Phone 7 devices. If you have a Zune HD, you can also download and add apps to your device. Here’s the detailed information window for the weather app.  Click Download to add it to your device.   Mini Mode The Zune player generally takes up a large portion of your screen, and is actually most impressive when run maximized.  However, if you’re simply wanting to enjoy your tunes while you’re using your computer, you can use the Mini mode to still view music info and control Zune in a smaller mode.  Click the Mini Player button near the window control buttons in the top right to activate it. Now Zune will take up much less of your desktop.  This window will stay on top of other windows so you can still easily view and control it. Zune will display an image of the artist if one is available, and this shows up in Mini mode more often than it does in the full mode. And, in Windows 7, you could simply minimize Zune as you can control it directly from the taskbar thumbnail preview.   Even more controls are available from Zune’s jumplist in Windows 7.  You can directly access your Quickplay links or choose to shuffle all music without leaving the taskbar. Settings Although Zune is designed to be used without confusing menus and settings, you can tweak the program to your liking from the settings panel.  Click Settings near the top left of the window. Here you can change file storage, types, burn, metadata, and many more settings.  You can also setup Zune to stream media to your XBOX 360 if you have one.   You can also customize Zune’s look with a variety of modern backgrounds and gradients. Conclusion If you’re ready for a fresh way to enjoy your media, Zune is designed for you.  It’s innovative UI definitely sets it apart from standard media players, and is very pleasing to use.  Zune is especially nice if your computer is using XP, Vista Home Basic, or 7 Starter as these versions of Windows don’t include Media Center.  Additionally, the mini player mode is a nice touch that brings a feature of Windows 7’s Media Player to XP and Vista.  Zune is definitely one of our favorite music apps.  Try it out, and get a fresh view of your music today!

  • A standard style guide or best-practice guide for web application development

    - by gutch
    I run a very small team of developers on a web application, just three people (and not even full time). We're all capable developers, but we write our code in very different ways: we name similar things in different ways, we use different HTML and CSS to achieve similar outcomes. We can manage this OK because we're small, but can't help feeling it would be better to get some standards in place. Are there any good style guides or best-practice guides for web application development that we can use to keep our code under control? Sure, we could write them ourselves. But the reality is that with lots to do and very few staff, we're not going to bother. We need something off the shelf that we can tinker with rather than start from scratch. What we're not looking for here is basic code formatting rules like "whether to use tabs or spaces" or "where to put line breaks" — we can control this by standardising our IDEs. What we are looking for are rules for code and markup. For example: What HTML markup should be used for headers, tables, sidebars, buttons, etc. When to add new CSS styles, and what to name them When IDs should be allocated to HTML elements, and what to name them How Javascript functions should be declared and called How to pick an appropriate URL for given page or AJAX call When to use each HTTP method, ie POST vs GET vs PUT etc How to name server-side methods (Java, in our case) How to throw and handle errors and exceptions in a consistent way etc, etc.

  • Using the JRockit Flight Recorder as an In-Flight Black Box

    - by Marcus Hirt
    The new JRockit Flight Recorder has some very interesting properties. It can be used like the black box of an airplane, allowing users to go back in time and check what was happening around the time when something went wrong. Here is how to enable the default continuous recording in JRockit to allow for that use case. The flight recorder is on by default in JRockit R28, the problem is that there is no recording running by default. To configure JRockit to start with the default recording running, add the parameter: -XX:FlightRecorderOptions=defaultrecording=true That will enable a recording with recording ID 0. You can see that it has been started properly by choosing Show Recordings from the context menu in JRockit Mission Control.   You should see something similar to the picture below. Simply right click on the recording and select dump to dump information available in the flight recorder. You can select to dump data for a specific period of time or all data. For more information about the command line parameters available to control the Flight Recorder, see the JRockit documentation.

  • Adding UCM as a search source in Windows Explorer

    - by kyle.hatlestad
    A customer recently pointed out to me that Windows 7 supports federated search within Windows Explorer. This means you can perform searches to external sources such as Google, Flickr, YouTube, etc right from within Explorer. While we do have the Desktop Integration Suite which offers searching within Explorer, I thought it would be interesting to look into this method which would not require any client software to implement. Basically, federated searching hooks up in Windows Explorer through the OpenSearch protocol. A Search Connector Descriptor file is run and it installs the search provider. The file is a .osdx file which is an OpenSearch Description document. It describes the search provider you are hooking up to along with the URL for the query. If those results can come back as an RSS or ATOM feed, then you're all set. So the first step is to install the RSS Feeds component from the UCM Samples page on OTN. If you're on 11g, I've found the RSS Feeds works just fine on that version too. Next, you want to perform a Quick Search with a particular search term and then copy the RSS link address for that search result. Here is what an example URL might looks like: http://server:16200/cs/idcplg?IdcService=GET_SCS_FEED&feedName=search_results&QueryText=%28+%3cqsch%3eoracle%3c%2fqsch %3e+%29&SortField=dInDate&SortOrder=Desc&ResultCount=20&SearchQueryFormat= Universal&SearchProviders=server& Now you want to create a new text file and start out with this information: <?xml version="1.0" encoding="UTF-8"?><OpenSearchDescription xmlns:ms-ose="http://schemas.microsoft.com/opensearchext/2009/"> <ShortName></ShortName> <Description></Description> <Url type="application/rss+xml" template=""/> <Url type="text/html" template=""/> </OpenSearchDescription> Enter a ShortName and Description. The ShortName will be the value used when displaying the search provider in Explorer. In the template attribute for the first Url element, enter the URL copied previously. You will then need to convert the ampersand symbols to '&' to make them XML compliant. Finally, you'll want to switch out the search term with '{searchTerms}'. For the second Url element, you can do the same thing except you want to copy the UCM search results URL from the page of results. That URL will look something like: http://server:16200/cs/idcplg?IdcService=GET_SEARCH_RESULTS&SortField=dInDate&SortOrder=Desc&ResultCount=20&QueryText=%3Cqsch%3Eoracle%3C%2Fqsch%3E&listTemplateId= &ftx=1&SearchQueryFormat=Universal&TargetedQuickSearchSelection= &MiniSearchText=oracle Again, convert the ampersand symbols and replace the search term with '{searchTerms}'. When complete, save the file with the .osdx extension. The completed file should look like: <?xml version="1.0" encoding="UTF-8"?> <OpenSearchDescription xmlns="http://a9.com/-/spec/opensearch/1.1/" xmlns:ms-ose="http://schemas.microsoft.com/opensearchext/2009/"> <ShortName>Universal Content Management</ShortName> <Description>OpenSearch for UCM via Windows 7 Search Federation.</Description> <Url type="application/rss+xml" template="http://server:16200/cs/idcplg?IdcService=GET_SCS_FEED&amp;feedName=search_results&amp;QueryText=%28+%3Cqsch%3E{searchTerms}%3C%2fqsch%3E+%29&amp;SortField=dInDate&amp;SortOrder=Desc&amp;ResultCount=200&amp;SearchQueryFormat=Universal"/> <Url type="text/html" template="http://server:16200/cs/idcplg?IdcService=GET_SEARCH_RESULTS&amp;SortField=dInDate&amp;SortOrder=Desc&amp;ResultCount=20&amp;QueryText=%3Cqsch%3E{searchTerms}%3C%2Fqsch%3E&amp;listTemplateId=&amp;ftx=1&amp;SearchQueryFormat=Universal&amp;TargetedQuickSearchSelection=&amp;MiniSearchText={searchTerms}"/> </OpenSearchDescription> After you save the file, simply double-click it to create the provider. It will ask if you want to add the search connector to Windows. Click Add and it will add it to the Searches folder in your user folder as well as your Favorites. Now just click on the search icon and in the upper right search box, enter your term. As you are typing, it begins executing searches and the results will come back in Explorer. Now when you double-click on an item, it will try and download the web viewable for viewing. You also have the ability to save the search, just as you would in UCM. And there is a link to Search On Website which will launch your browser and go directly to the search results page there. And with some tweaks to the RSS component, you can make the results a bit more interesting. It supports the Media RSS standard, so you can pass along the thumbnail of the documents in the results. To enable this, edit the rss_resources.htm file in the RSS Feeds component. In the std_rss_feed_begin resource include, add the namespace 'xmlns:media="http://search.yahoo.com/mrss/' to the rss definition: <rss version="2.0" xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:sy="http://purl.org/rss/1.0/modules/syndication/" xmlns:media="http://search.yahoo.com/mrss/"> Next, in the rss_channel_item_with_thumb include, below the closing image element, add this element: </images> <media:thumbnail url="<$if strIndexOf(thumbnailUrl, "@t") > 0 or strIndexOf(thumbnailUrl, "@g") > 0 or strIndexOf(thumbnailUrl, "@p") > 0$><$rssHttpHost$><$thumbnailUrl$><$elseif dGif$><$HttpWebRoot$>images/docgifs/<$dGif$><$endif$>" /> <description> This and lots of other tweaks can be done to the RSS component to help extend it for optimum use in Explorer. Hopefully this can get you started. *Note: This post also applies to Universal Records Management (URM).

  • SQL SERVER – Import CSV into Database – Transferring File Content into a Database Table using CSVexpress

    - by pinaldave
    One of the most common data integration tasks I run into is a desire to move data from a file into a database table.  Generally the user is familiar with his data, the structure of the file, and the database table, but is unfamiliar with data integration tools and therefore views this task as something that is difficult.  What these users really need is a point and click approach that minimizes the learning curve for the data integration tool.  This is what CSVexpress (www.CSVexpress.com) is all about!  It is based on expressor Studio, a data integration tool I’ve been reviewing over the last several months. With CSVexpress, moving data between data sources can be as simple as providing the database connection details, describing the structure of the incoming and outgoing data and then connecting two pre-programmed operators.   There’s no need to learn the intricacies of the data integration tool or to write code.  Let’s look at an example. Suppose I have a comma separated value data file with data similar to the following, which is a listing of terminated employees that includes their hiring and termination date, department, job description, and final salary. EMP_ID,STRT_DATE,END_DATE,JOB_ID,DEPT_ID,SALARY 102,13-JAN-93,24-JUL-98 17:00,Programmer,60,"$85,000" 101,21-SEP-89,27-OCT-93 17:00,Account Representative,110,"$65,000" 103,28-OCT-93,15-MAR-97 17:00,Account Manager,110,"$75,000" 304,17-FEB-96,19-DEC-99 17:00,Marketing,20,"$45,000" 333,24-MAR-98,31-DEC-99 17:00,Data Entry Clerk,50,"$35,000" 100,17-SEP-87,17-JUN-93 17:00,Administrative Assistant,90,"$40,000" 334,24-MAR-98,31-DEC-98 17:00,Sales Representative,80,"$40,000" 400,01-JAN-99,31-DEC-99 17:00,Sales Manager,80,"$55,000" Notice the concise format used for the date values, the fact that the termination date includes both date and time information, and that the salary is clearly identified as money by the dollar sign and digit grouping.  In moving this data to a database table I want to express the dates using a format that includes the century since it’s obvious that this listing could include employees who left the company in both the 20th and 21st centuries, and I want the salary to be stored as a decimal value without the currency symbol and grouping character.  Most data integration tools would require coding within a transformation operation to effect these changes, but not expressor Studio.  Directives for these modifications are included in the description of the incoming data. Besides starting the expressor Studio tool and opening a project, the first step is to create connection artifacts, which describe to expressor where data is stored.  For this example, two connection artifacts are required: a file connection, which encapsulates the file system location of my file; and a database connection, which encapsulates the database connection information.  With expressor Studio, I use wizards to create these artifacts. First click New Connection > File Connection in the Home tab of expressor Studio’s ribbon bar, which starts the File Connection wizard.  In the first window, I enter the path to the directory that contains the input file.  Note that the file connection artifact only specifies the file system location, not the name of the file. Then I click Next and enter a meaningful name for this connection artifact; clicking Finish closes the wizard and saves the artifact. To create the Database Connection artifact, I must know the location of, or instance name, of the target database and have the credentials of an account with sufficient privileges to write to the target table.  To use expressor Studio’s features to the fullest, this account should also have the authority to create a table. I click the New Connection > Database Connection in the Home tab of expressor Studio’s ribbon bar, which starts the Database Connection wizard.  expressor Studio includes high-performance drivers for many relational database management systems, so I can simply make a selection from the “Supplied database drivers” drop down control.  If my desired RDBMS isn’t listed, I can optionally use an existing ODBC DSN by selecting the “Existing DSN” radio button. In the following window, I enter the connection details.  With Microsoft SQL Server, I may choose to use Windows Authentication rather than rather than account credentials.  After clicking Next, I enter a meaningful name for this connection artifact and clicking Finish closes the wizard and saves the artifact. Now I create a schema artifact, which describes the structure of the file data.  When expressor reads a file, all data fields are typed as strings.  In some use cases this may be exactly what is needed and there is no need to edit the schema artifact.  But in this example, editing the schema artifact will be used to specify how the data should be transformed; that is, reformat the dates to include century designations, change the employee and job ID’s to integers, and convert the salary to a decimal value. Again a wizard is used to create the schema artifact.  I click New Schema > Delimited Schema in the Home tab of expressor Studio’s ribbon bar, which starts the Database Connection wizard.  In the first window, I click Get Data from File, which then displays a listing of the file connections in the project.  When I click on the file connection I previously created, a browse window opens to this file system location; I then select the file and click Open, which imports 10 lines from the file into the wizard. I now view the file’s content and confirm that the appropriate delimiter characters are selected in the “Field Delimiter” and “Record Delimiter” drop down controls; then I click Next. Since the input file includes a header row, I can easily indicate that fields in the file should be identified through the corresponding header value by clicking “Set All Names from Selected Row. “ Alternatively, I could enter a different identifier into the Field Details > Name text box.  I click Next and enter a meaningful name for this schema artifact; clicking Finish closes the wizard and saves the artifact. Now I open the schema artifact in the schema editor.  When I first view the schema’s content, I note that the types of all attributes in the Semantic Type (the right-hand panel) are strings and that the attribute names are the same as the field names in the data file.  To change an attribute’s name and type, I highlight the attribute and click Edit in the Attributes grouping on the Schema > Edit tab of the editor’s ribbon bar.  This opens the Edit Attribute window; I can change the attribute name and select the desired type from the “Data type” drop down control.  In this example, I change the name of each attribute to the name of the corresponding database table column (EmployeeID, StartingDate, TerminationDate, JobDescription, DepartmentID, and FinalSalary).  Then for the EmployeeID and DepartmentID attributes, I select Integer as the data type, for the StartingDate and TerminationDate attributes, I select Datetime as the data type, and for the FinalSalary attribute, I select the Decimal type. But I can do much more in the schema editor.  For the datetime attributes, I can set a constraint that ensures that the data adheres to some predetermined specifications; a starting date must be later than January 1, 1980 (the date on which the company began operations) and a termination date must be earlier than 11:59 PM on December 31, 1999.  I simply select the appropriate constraint and enter the value (1980-01-01 00:00 as the starting date and 1999-12-31 11:59 as the termination date). As a last step in setting up these datetime conversions, I edit the mapping, describing the format of each datetime type in the source file. I highlight the mapping line for the StartingDate attribute and click Edit Mapping in the Mappings grouping on the Schema > Edit tab of the editor’s ribbon bar.  This opens the Edit Mapping window in which I either enter, or select, a format that describes how the datetime values are represented in the file.  Note the use of Y01 as the syntax for the year.  This syntax is the indicator to expressor Studio to derive the century by setting any year later than 01 to the 20th century and any year before 01 to the 21st century.  As each datetime value is read from the file, the year values are transformed into century and year values. For the TerminationDate attribute, my format also indicates that the datetime value includes hours and minutes. And now to the Salary attribute. I open its mapping and in the Edit Mapping window select the Currency tab and the “Use currency” check box.  This indicates that the file data will include the dollar sign (or in Europe the Pound or Euro sign), which should be removed. And on the Grouping tab, I select the “Use grouping” checkbox and enter 3 into the “Group size” text box, a comma into the “Grouping character” text box, and a decimal point into the “Decimal separator” character text box. These entries allow the string to be properly converted into a decimal value. By making these entries into the schema that describes my input file, I’ve specified how I want the data transformed prior to writing to the database table and completely removed the requirement for coding within the data integration application itself. Assembling the data integration application is simple.  Onto the canvas I drag the Read File and Write Table operators, connecting the output of the Read File operator to the input of the Write Table operator. Next, I select the Read File operator and its Properties panel opens on the right-hand side of expressor Studio.  For each property, I can select an appropriate entry from the corresponding drop down control.  Clicking on the button to the right of the “File name” text box opens the file system location specified in the file connection artifact, allowing me to select the appropriate input file.  I indicate also that the first row in the file, the header row, should be skipped, and that any record that fails one of the datetime constraints should be skipped. I then select the Write Table operator and in its Properties panel specify the database connection, normal for the “Mode,” and the “Truncate” and “Create Missing Table” options.  If my target table does not yet exist, expressor will create the table using the information encapsulated in the schema artifact assigned to the operator. The last task needed to complete the application is to create the schema artifact used by the Write Table operator.  This is extremely easy as another wizard is capable of using the schema artifact assigned to the Read Table operator to create a schema artifact for the Write Table operator.  In the Write Table Properties panel, I click the drop down control to the right of the “Schema” property and select “New Table Schema from Upstream Output…” from the drop down menu. The wizard first displays the table description and in its second screen asks me to select the database connection artifact that specifies the RDBMS in which the target table will exist.  The wizard then connects to the RDBMS and retrieves a list of database schemas from which I make a selection.  The fourth screen gives me the opportunity to fine tune the table’s description.  In this example, I set the width of the JobDescription column to a maximum of 40 characters and select money as the type of the LastSalary column.  I also provide the name for the table. This completes development of the application.  The entire application was created through the use of wizards and the required data transformations specified through simple constraints and specifications rather than through coding.  To develop this application, I only needed a basic understanding of expressor Studio, a level of expertise that can be gained by working through a few introductory tutorials.  expressor Studio is as close to a point and click data integration tool as one could want and I urge you to try this product if you have a need to move data between files or from files to database tables. Check out CSVexpress in more detail.  It offers a few basic video tutorials and a preview of expressor Studio 3.5, which will support the reading and writing of data into Salesforce.com.

  • Best SEO practices for mobile URLs: 301, rel=canonical, or something else?

    - by Chris
    I am developing a site with a mobile version and am trying to figure the appropriate way to manage the URLs for search engines. So far I've considered: Having a mobile site with rel="canonical" links to the regular site. Putting both the mobile site and full site on one URL, and doing user agent sniffing. Another opinion: Spencer: "If you have a mobile site at a separate location or URL, you should 301 redirect each and every mobile page to its corresponding page on your main website. Employ user agent detection so that the mobile optimized version is served up if someone's coming in from a hand-held. - http://developer.practicalecommerce.com/articles/1722-Mobile-site-Development-Best-Practices-for-SEO-Usability Both 2 and 3 make it hard for a user who wants to switch to the full site or mobile site manually, but I'm not sure 1 is the best alternative. What's the best way to write URLs for a mobile site?

  • New Themes New Benefits (WinForms)

    We believe that working hard on something can be great fun at the end when everything is done and the seeds have resulted in the sweetest fruits. This is the case with the new Theming Mechanism and the new Visual Style Builder which we introduced as of Q1 2010.   I am not going to dive into any details on the new concepts behind all this stuff, but will simply focus on the numbers: both in terms of loading speed and memory usage. As you may already know, the new approach we use to style our controls uses the so called Style Repository which stores style settings that can be reused throughout the whole theme. As a result, we have estimated that the size of our themes has been significantly reduced. For instance, the size of all XML files of the Desert theme sums up to 1.83 MB. The case with the new version of the Desert theme is drastically different. Despite the fact that the new theme consists of more XML files compared to the old, its size is only 707 KB!   Furthermore, we have performed a simple performance test since the common sense tells us that such a great improvement in terms of memory footprint should be followed by a great improvement in terms of speed. We have estimated that loading and applying the new Desert theme to a form containing all RadControls for WinForms takes roughly 30% less time compared to the same operation with the old version of the Desert theme. The following screenshots briefly demonstrate the scenario which we used to estimate the loading time difference between the old and the new Desert theme:     Here, the old Desert theme is applied to all controls on the Form which takes almost 1,3 seconds.     Applying the new Desert theme (based on the new Theming Mechanism) takes about 0,78 seconds.   On top of all these great improvements, we can add the fact that the new Visual Style Builder significantly reduces the time needed to style a control by entirely changing the approach compared to the old version of this tool. You can be sure that we have already prepared some great new stuff for Q1 2010 SP1 that will simplify things further so that designing themes with the new VSB will become more fun than ever!Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • Caching NHibernate Named Queries

    - by TStewartDev
    I recently started a new job and one of my first tasks was to implement a "popular products" design. The parameters were that it be done with NHibernate and be cached for 24 hours at a time because the query will be pretty taxing and the results do not need to be constantly up to date. This ended up being tougher than it sounds. The database schema meant a minimum of four joins with filtering and ordering criteria. I decided to use a stored procedure rather than letting NHibernate create the SQL for me. Here is a summary of what I learned (even if I didn't ultimately use all of it): You can't, at the time of this writing, use Fluent NHibernate to configure SQL named queries or imports You can return persistent entities from a stored procedure and there are a couple ways to do that You can populate POCOs using the results of a stored procedure, but it isn't quite as obvious You can reuse your named query result mapping other places (avoid duplication) Caching your query results is not at all obvious Testing to see if your cache is working is a pain NHibernate does a lot of things right. Having unified, up-to-date, comprehensive, and easy-to-find documentation is not one of them. By the way, if you're new to this, I'll use the terms "named query" and "stored procedure" (from NHibernate's perspective) fairly interchangeably. Technically, a named query can execute any SQL, not just a stored procedure, and a stored procedure doesn't have to be executed from a named query, but for reusability, it seems to me like the best practice. If you're here, chances are good you're looking for answers to a similar problem. You don't want to read about the path, you just want the result. So, here's how to get this thing going. The Stored Procedure NHibernate has some guidelines when using stored procedures. For Microsoft SQL Server, you have to return a result set. The scalar value that the stored procedure returns is ignored as are any result sets after the first. Other than that, it's nothing special. CREATE PROCEDURE GetPopularProducts @StartDate DATETIME, @MaxResults INT AS BEGIN SELECT [ProductId], [ProductName], [ImageUrl] FROM SomeTableWithJoinsEtc END The Result Class - PopularProduct You have two options to transport your query results to your view (or wherever is the final destination): you can populate an existing mapped entity class in your model, or you can create a new entity class. If you go with the existing model, the advantage is that the query will act as a loader and you'll get full proxied access to the domain model. However, this can be a disadvantage if you require access to the related entities that aren't loaded by your results. For example, my PopularProduct has image references. Unless I tie them into the query (thus making it even more complicated and expensive to run), they'll have to be loaded on access, requiring more trips to the database. Since we're trying to avoid trips to the database by using a second-level cache, we should use the second option, which is to create a separate entity for results. This approach is (I believe) in the spirit of the Command-Query Separation principle, and it allows us to flatten our data and optimize our report-generation process from data source to view. public class PopularProduct { public virtual int ProductId { get; set; } public virtual string ProductName { get; set; } public virtual string ImageUrl { get; set; } } The NHibernate Mappings (hbm) Next up, we need to let NHibernate know about the query and where the results will go. Below is the markup for the PopularProduct class. Notice that I'm using the <resultset> element and that it has a name attribute. The name allows us to drop this into our query map and any others, giving us reusability. Also notice the <import> element which lets NHibernate know about our entity class. <?xml version="1.0" encoding="utf-8" ?> <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"> <import class="PopularProduct, Infrastructure.NHibernate, Version=1.0.0.0"/> <resultset name="PopularProductResultSet"> <return-scalar column="ProductId" type="System.Int32"/> <return-scalar column="ProductName" type="System.String"/> <return-scalar column="ImageUrl" type="System.String"/> </resultset> </hibernate-mapping>  And now the PopularProductsMap: <?xml version="1.0" encoding="utf-8" ?> <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"> <sql-query name="GetPopularProducts" resultset-ref="PopularProductResultSet" cacheable="true" cache-mode="normal"> <query-param name="StartDate" type="System.DateTime" /> <query-param name="MaxResults" type="System.Int32" /> exec GetPopularProducts @StartDate = :StartDate, @MaxResults = :MaxResults </sql-query> </hibernate-mapping>  The two most important things to notice here are the resultset-ref attribute, which links in our resultset mapping, and the cacheable attribute. The Query Class – PopularProductsQuery So far, this has been fairly obvious if you're familiar with NHibernate. This next part, maybe not so much. You can implement your query however you want to; for me, I wanted a self-encapsulated Query class, so here's what it looks like: public class PopularProductsQuery : IPopularProductsQuery { private static readonly IResultTransformer ResultTransformer; private readonly ISessionBuilder _sessionBuilder;   static PopularProductsQuery() { ResultTransformer = Transformers.AliasToBean<PopularProduct>(); }   public PopularProductsQuery(ISessionBuilder sessionBuilder) { _sessionBuilder = sessionBuilder; }   public IList<PopularProduct> GetPopularProducts(DateTime startDate, int maxResults) { var session = _sessionBuilder.GetSession(); var popularProducts = session .GetNamedQuery("GetPopularProducts") .SetCacheable(true) .SetCacheRegion("PopularProductsCacheRegion") .SetCacheMode(CacheMode.Normal) .SetReadOnly(true) .SetResultTransformer(ResultTransformer) .SetParameter("StartDate", startDate.Date) .SetParameter("MaxResults", maxResults) .List<PopularProduct>();   return popularProducts; } }  Okay, so let's look at each line of the query execution. The first, GetNamedQuery, matches up with our NHibernate mapping for the sql-query. Next, we set it as cacheable (this is probably redundant since our mapping also specified it, but it can't hurt, right?). Then we set the cache region which we'll get to in the next section. Set the cache mode (optional, I believe), and my cache is read-only, so I set that as well. The result transformer is very important. This tells NHibernate how to transform your query results into a non-persistent entity. You can see I've defined ResultTransformer in the static constructor using the AliasToBean transformer. The name is obviously leftover from Java/Hibernate. Finally, set your parameters and then call a result method which will execute the query. Because this is set to cached, you execute this statement every time you run the query and NHibernate will know based on your parameters whether to use its cached version or a fresh version. The Configuration – hibernate.cfg.xml and Web.config You need to explicitly enable second-level caching in your hibernate configuration: <hibernate-configuration xmlns="urn:nhibernate-configuration-2.2"> <session-factory> [...] <property name="dialect">NHibernate.Dialect.MsSql2005Dialect</property> <property name="cache.provider_class">NHibernate.Caches.SysCache.SysCacheProvider,NHibernate.Caches.SysCache</property> <property name="cache.use_query_cache">true</property> <property name="cache.use_second_level_cache">true</property> [...] </session-factory> </hibernate-configuration> Both properties "use_query_cache" and "use_second_level_cache" are necessary. As this is for a web deployement, we're using SysCache which relies on ASP.NET's caching. Be aware of this if you're not deploying to the web! You'll have to use a different cache provider. We also need to tell our cache provider (in this cache, SysCache) about our caching region: <syscache> <cache region="PopularProductsCacheRegion" expiration="86400" priority="5" /> </syscache> Here I've set the cache to be valid for 24 hours. This XML snippet goes in your Web.config (or in a separate file referenced by Web.config, which helps keep things tidy). The Payoff That should be it! At this point, your queries should run once against the database for a given set of parameters and then use the cache thereafter until it expires. You can, of course, adjust settings to work in your particular environment. Testing Testing your application to ensure it is using the cache is a pain, but if you're like me, you want to know that it's actually working. It's a bit involved, though, so I'll create a separate post for it if comments indicate there is interest.

  • Accessing Server-Side Data from Client Script: Accessing JSON Data From an ASP.NET Page Using jQuery

    When building a web application, we must decide how and when the browser will communicate with the web server. The ASP.NET WebForms model greatly simplifies web development by providing a straightforward mechanism for exchanging data between the browser and the server. With WebForms, each ASP.NET page's rendered output includes a <form> element that performs a postback to the same page whenever a Button control within the form is clicked, or whenever the user modifies a control whose AutoPostBack property is set to True. On postback, the server sends the entire contents of the web page back to the browser, which then displays this new content. With WebForms we don't need to spend much time or effort thinking about how or when the browser will communicate with the server or how that returned information will be processed by the browser. It just works. While this approach certainly works and has its advantages, it's not without its drawbacks. The primary concern with postback forms is that they require a large amount of information to be exchanged between the browser and the server. Specifically, the browser sends back all of its form fields (including hidden ones, like view state, which may be quite large) and then the server sends back the entire contents of the web page. Granted, there are scenarios where this large quantity of data needs to be exchanged, but in many cases we can use techniques that exchange much less information. However, these techniques necessitate spending more time and effort thinking about how and when to have the browser communicate with the server and intelligently deciding on what information needs to be exchanged. This article, the first in a multi-part series, examines different techniques for accessing server-side data from a browser using client-side script. Throughout this series we will explore alternative ways to expose data on the server so that it can be accessed from the browser using script; we will also examine various tools for communicating with the server from JavaScript, including jQuery and the ASP.NET AJAX library.

  • Going back (downgrade) from LibreOffice 4 to LibreOffice 3

    - by MMA
    EDIT This question is not at all a duplicate of How to downgrade from LibreOffice 4.0 to 3.6? The above mentioned question talks about downgrading from a specific version of LibreOffice, namely from 4.0 to 3.6. The solutions mentioned are not the ones I am looking for. They will work but I wanted a general solution without using PPA or downloading .deb files for from a higher version to a lower version. The above solutions suggest either downloading .deb files for LibreOffice 3.6 or adding repository for it. Furthermore, some of the answers put out-of-proportion~(applicable for the solution, however) stress on use of synaptic, not general command-line-solution. That made me wonder, at this very moment, if I take a fresh computer, and install Ubuntu 12.04, LibreOffice installation will work without a hitch. Then why I can not install LibreOffice in my 12.04 machine today from simple command line? This answer to my question, clarified everything. I need to use ppa-purge so that this resets all packages from a PPA to the standard versions released for my distribution. Basically it is like a way to restore my system back to the way it was before my installed packages from a PPA. This article further elaborates the idea. The above mentioned answer worked perfectly for me. Actually, this was an education for me since it taught me how do downgrade a package that was added via PPA. I had upgraded from LibreOffice 3 to LibreOffice 4 using the PPA. Now since I found that LibreOffice 4 has some issues, including handling my native language, I want to move back to LibreOffice 3. In order to accomplish this, I removed the LibreOffice config directory from my home and then purged LibreOffice from my machine. sudo apt-get purge libreoffice-* Then I removed the relevant PPA's using the sudo apt-add-repository --remove command. And then ran sudo apt-get update. Now, when I try to install LibreOffice using the command sudo apt-get install libreoffice I get an avalanche of output about unmet dependencies, something like, The following packages have unmet dependencies: libreoffice : Depends: libreoffice-core (= 1:3.5.7-0ubuntu4) but it is not going to be installed (snipped) If I dig the issue further, by using the command, sudo apt-get install libreoffice-core I get The following packages have unmet dependencies: libreoffice-core : Depends: libreoffice-common (> 1:3.5.7) but it is not going to be installed Depends: libexttextcat0 (>= 2.2-8) but it is not going to be installed Depends: ure (>= 3.5.7~) but it is not going to be installed E: Unable to correct problems, you have held broken packages. Could you please tell me how do I install LibreOffice 3 in my machine? I am using Ubuntu 12.04 LTS.

    I installed selinux first, I set SELINUX=enforcing instead of its original value, SELINUX=permissive in /etc/selinux/config, then I reboot my computer. I waited for some time, but it stopped, I rebooted again and it can not go into the system anymore so I restored the setting. I tried to run seinfo command in a terminal, but it output some errors below: ERROR: policydb version 26 does not match my version range 15-24 ERROR: Unable to open policy /etc/selinux/ubuntu/policy/policy.26.

  • Article - Create a MapView in Google Maps for iOS

    - by Wallym
    With the introduction of iOS 6 in September 2012, Apple Inc. removed the map system based on Google Maps and introduced its own map system for iPhone and iPad users. The introduction of Apple Maps, like any new technology, came with its own problems. In December 2012, Google released its Google Maps SDK for iOS. (Check the Google Maps SDK for iOS page for additional documentation as new features are deployed to the product.) Google Maps for iOS has a long, solid track record, given the use of its data in Android and many years of usage. The introduction of Google Maps for iOS has resulted in a measurable increase in the number of users who have updated their existing iPhones from iOS version 5 to iOS version 6. This article will look at using Google Maps for iOS using Xamarin.iOS.Article url: http://visualstudiomagazine.com/articles/2013/06/01/how-to-use-google-maps-for-ios.asp

  • Site Studio Mobile Example - WCM Reuse

    - by john.brunswick
    Mobile internet usage is growing by leaps and bounds and it is theorized that in the not-to-distant future it will eclipse traditional access via desktop browsers. Mary Meeker, a managing director at Morgan Stanley and head of their global technology research team, recently predicted that mobile usage will eclipse desktop usage within the next 5 years in an Events@Google series presentation. In order for organizations to reach their prospects, customers and business partners, they will need to make their content readily available on mobile devices. A few years ago it was fairly challenging to provide a special, separate, site to cater to mobile users using technologies like WML (Wireless Markup Language). Modern mobile browsers have rendered the need for this as irrelevant and now the focus has moved toward providing a browsing experience that works well on small screen sizes and is highly performant. What does all of this mean for Oracle UCM? Taking site content from an existing Site Studio site and targeting it for consumption for mobile devices is a very straightforward process that is aided by a number of native capabilities in the product. The example highlighted in this post takes advantage of dynamic conversion capabilities in Oracle UCM to enable site content to be created and updated via MS Office documents. These documents are then converted to a simple, clean HTML format for consumption in the desktop and mobile browsing experiences. To help better understand how this is possible the example below shows a fictional .COM and its mobile site counterpart that both leverage the same underlying content. The scenario is not complete or production ready, but highlights that a mobile experience may be best delivered by omitting portions of a site that would be present within the version served to desktop clients. If you have browsed CNet (news.com) on a mobile device it becomes quickly apparent that they are serving an optimized version for your mobile device. An iPhone style version can be accessed at http://iphone.cnet.com/. In order to do that they leveraged some work done for the iPhone iUi project developed by Joe Hewitt that provides mobile browsers an experience that is similar to what users may find in a native iPhone application. For our example parts of this framework are used (the CSS) and this approach provides a page that will degrade nicely over a wide range of mobile browsers, since it is comprised of lightweight HTML markup and CSS. The iPhone iUi framework also provides some nice JavaScript to enable animated transitions between pages, but for the widest range of mobile browser compatibility we will only incorporate the CSS and HTML DIV / UL based page markup in our example.

  • WinXP How to Tunnel LPT over USB

    - by Michael Pruitt
    I have a windows program that accesses a device connected to a LPT (1-3) 25 pin port. The communication is bidirectional, and I suspected the control lines are also accessed directly. I would like to migrate the device to a machine that does not have a LPT port. I saw the dos2usb software, but that takes the output (from a DOS program) and 'prints' it formatted for a specific printer. I need a raw LPT connection, and a cable that provides access to all the control signals. I do have a USB to 36-pin Centronics that may have the extra signals. I use it with a vinyl cutter that doesn't like most of the USB dongles. It comes up as USB001. Would adding and sharing a generic printer, then mapping LPT1 to the share get me closer? Would that work for a parallel port scanner? My preferred solution is a USB cable with a driver that will map it to LPT1, LPT2, or LPT3.

  • apache2 force proxy for specific url on a subdomain

    - by Tony G.
    Hi, I have a site that has dynamic virtual subdomains using mod_rewrite, as defined like this: <VirtualHost *:80> ServerName example.com ServerAlias *.example.com DocumentRoot /var/www/example.com/www RewriteEngine on RewriteCond %{HTTP_HOST} ^[^.]+\.examle.com$ RewriteRule ^(.+) %{HTTP_HOST}$1 [C] RewriteRule ^([^.]+)\.example.com(.*) /var/www/example.com/$1$2 </VirtualHost> The problem is that I want a specific url, say subdomain.example.com/CONTROL/ to point back to www.example.com/ using a proxy (not url redirecting). I have tried adding: RewriteRule ^([^.]+)\.example.com/CONTROL(.*) /var/www/example.com/www$2 [P] But that didn't work. Any ideas?

  • How do I setup an FTP server on Windows 7?

    - by Matt Frear
    I'm having trouble getting an FTP server setup on Windows 7. I've added the service using Control Panel - Programs - Turn Windows features on and off. I can see the service has started in Control Panel - Services. But then when I fire up a Windows command-line window, cmd, I get Not connected., C:\Users\mattf>ftp localhost ftp> ls Not connected. ftp> open localhost ftp> ls Not connected. ftp> dir Not connected. ftp> quit C:\Users\mattf> And that's as far as I've got. I have no idea why this isn't working - could it be firewall settings?

  • Commit in SQL

    - by PRajkumar
    SQL Transaction Control Language Commands (TCL)                                           (COMMIT) Commit Transaction As a SQL language we use transaction control language very frequently. Committing a transaction means making permanent the changes performed by the SQL statements within the transaction. A transaction is a sequence of SQL statements that Oracle Database treats as a single unit. This statement also erases all save points in the transaction and releases transaction locks. Oracle Database issues an implicit COMMIT before and after any data definition language (DDL) statement. Oracle recommends that you explicitly end every transaction in your application programs with a COMMIT or ROLLBACK statement, including the last transaction, before disconnecting from Oracle Database. If you do not explicitly commit the transaction and the program terminates abnormally, then the last uncommitted transaction is automatically rolled back.   Until you commit a transaction: ·         You can see any changes you have made during the transaction by querying the modified tables, but other users cannot see the changes. After you commit the transaction, the changes are visible to other users' statements that execute after the commit ·         You can roll back (undo) any changes made during the transaction with the ROLLBACK statement   Note: Most of the people think that when we type commit data or changes of what you have made has been written to data files, but this is wrong when you type commit it means that you are saying that your job has been completed and respective verification will be done by oracle engine that means it checks whether your transaction achieved consistency when it finds ok it sends a commit message to the user from log buffer but not from data buffer, so after writing data in log buffer it insists data buffer to write data in to data files, this is how it works.   Before a transaction that modifies data is committed, the following has occurred: ·         Oracle has generated undo information. The undo information contains the old data values changed by the SQL statements of the transaction ·         Oracle has generated redo log entries in the redo log buffer of the System Global Area (SGA). The redo log record contains the change to the data block and the change to the rollback block. These changes may go to disk before a transaction is committed ·         The changes have been made to the database buffers of the SGA. These changes may go to disk before a transaction is committed   Note:   The data changes for a committed transaction, stored in the database buffers of the SGA, are not necessarily written immediately to the data files by the database writer (DBWn) background process. This writing takes place when it is most efficient for the database to do so. It can happen before the transaction commits or, alternatively, it can happen some times after the transaction commits.   When a transaction is committed, the following occurs: 1.      The internal transaction table for the associated undo table space records that the transaction has committed, and the corresponding unique system change number (SCN) of the transaction is assigned and recorded in the table 2.      The log writer process (LGWR) writes redo log entries in the SGA's redo log buffers to the redo log file. It also writes the transaction's SCN to the redo log file. This atomic event constitutes the commit of the transaction 3.      Oracle releases locks held on rows and tables 4.      Oracle marks the transaction complete   Note:   The default behavior is for LGWR to write redo to the online redo log files synchronously and for transactions to wait for the redo to go to disk before returning a commit to the user. However, for lower transaction commit latency application developers can specify that redo be written asynchronously and that transaction do not need to wait for the redo to be on disk.   The syntax of Commit Statement is   COMMIT [WORK] [COMMENT ‘your comment’]; ·         WORK is optional. The WORK keyword is supported for compliance with standard SQL. The statements COMMIT and COMMIT WORK are equivalent. Examples Committing an Insert INSERT INTO table_name VALUES (val1, val2); COMMIT WORK; ·         COMMENT Comment is also optional. This clause is supported for backward compatibility. Oracle recommends that you used named transactions instead of commit comments. Specify a comment to be associated with the current transaction. The 'text' is a quoted literal of up to 255 bytes that Oracle Database stores in the data dictionary view DBA_2PC_PENDING along with the transaction ID if a distributed transaction becomes in doubt. This comment can help you diagnose the failure of a distributed transaction. Examples The following statement commits the current transaction and associates a comment with it: COMMIT     COMMENT 'In-doubt transaction Code 36, Call (415) 555-2637'; ·         WRITE Clause Use this clause to specify the priority with which the redo information generated by the commit operation is written to the redo log. This clause can improve performance by reducing latency, thus eliminating the wait for an I/O to the redo log. Use this clause to improve response time in environments with stringent response time requirements where the following conditions apply: The volume of update transactions is large, requiring that the redo log be written to disk frequently. The application can tolerate the loss of an asynchronously committed transaction. The latency contributed by waiting for the redo log write to occur contributes significantly to overall response time. You can specify the WAIT | NOWAIT and IMMEDIATE | BATCH clauses in any order. Examples To commit the same insert operation and instruct the database to buffer the change to the redo log, without initiating disk I/O, use the following COMMIT statement: COMMIT WRITE BATCH; Note: If you omit this clause, then the behavior of the commit operation is controlled by the COMMIT_WRITE initialization parameter, if it has been set. The default value of the parameter is the same as the default for this clause. Therefore, if the parameter has not been set and you omit this clause, then commit records are written to disk before control is returned to the user. WAIT | NOWAIT Use these clauses to specify when control returns to the user. The WAIT parameter ensures that the commit will return only after the corresponding redo is persistent in the online redo log. Whether in BATCH or IMMEDIATE mode, when the client receives a successful return from this COMMIT statement, the transaction has been committed to durable media. A crash occurring after a successful write to the log can prevent the success message from returning to the client. In this case the client cannot tell whether or not the transaction committed. The NOWAIT parameter causes the commit to return to the client whether or not the write to the redo log has completed. This behavior can increase transaction throughput. With the WAIT parameter, if the commit message is received, then you can be sure that no data has been lost. Caution: With NOWAIT, a crash occurring after the commit message is received, but before the redo log record(s) are written, can falsely indicate to a transaction that its changes are persistent. If you omit this clause, then the transaction commits with the WAIT behavior. IMMEDIATE | BATCH Use these clauses to specify when the redo is written to the log. The IMMEDIATE parameter causes the log writer process (LGWR) to write the transaction's redo information to the log. This operation option forces a disk I/O, so it can reduce transaction throughput. The BATCH parameter causes the redo to be buffered to the redo log, along with other concurrently executing transactions. When sufficient redo information is collected, a disk write of the redo log is initiated. This behavior is called "group commit", as redo for multiple transactions is written to the log in a single I/O operation. If you omit this clause, then the transaction commits with the IMMEDIATE behavior. ·         FORCE Clause Use this clause to manually commit an in-doubt distributed transaction or a corrupt transaction. ·         In a distributed database system, the FORCE string [, integer] clause lets you manually commit an in-doubt distributed transaction. The transaction is identified by the 'string' containing its local or global transaction ID. To find the IDs of such transactions, query the data dictionary view DBA_2PC_PENDING. You can use integer to specifically assign the transaction a system change number (SCN). If you omit integer, then the transaction is committed using the current SCN. ·         The FORCE CORRUPT_XID 'string' clause lets you manually commit a single corrupt transaction, where string is the ID of the corrupt transaction. Query the V$CORRUPT_XID_LIST data dictionary view to find the transaction IDs of corrupt transactions. You must have DBA privileges to view the V$CORRUPT_XID_LIST and to specify this clause. ·         Specify FORCE CORRUPT_XID_ALL to manually commit all corrupt transactions. You must have DBA privileges to specify this clause. Examples Forcing an in doubt transaction. Example The following statement manually commits a hypothetical in-doubt distributed transaction. Query the V$CORRUPT_XID_LIST data dictionary view to find the transaction IDs of corrupt transactions. You must have DBA privileges to view the V$CORRUPT_XID_LIST and to issue this statement. COMMIT FORCE '22.57.53';
