Let's see if I'll continue.<br />For some time I have been developing a new EPiServer 7 CMS site in ASP.NET MVC. I got stuck into a problem last week.

[Transaction (Process ID 105) was deadlocked on lock | communication buffer resources with another process and has been chosen as the deadlock victim. Rerun the transaction.]</strong></p> <p><a href="/link/d134a235dcd1449c989f5280e94fa277.png"><img style="border-right-width: 0px; display: inline; border-top-width: 0px; border-bottom-width: 0px; border-left-width: 0px" title="image" border="0" alt="image" src="/link/c321c42f30914a72884b10bc51b22f41.png" width="567" height="77" /></a> </p> <h2>Cause of the error</h2> <p>The error comes from the SQL-server when the subscription job executes the method ProfileManager.GetAllProfiles(). From my investigations the error appears when users are registering to the site during this method is executed. On large sites this is a very common situation. Users do register all the time. </p> <h2></h2> <h2>Solution</h2> <p>I have used Reflector to copy all code in EPiServer’s class SubscriptionJob to a new customized subscripttion job.</p> <p>I made some changes to the code. First of all there are some code that could be optimized. In my application the execution time for the subscription job has gone from 30 to 6 minutes, by implementing this fix.</p> <p>In the method protected virtual int SendSubscriptions(EPiServerProfile profile) there is no check if the user does subscribe to any pages or not. When you have large number of users and also a custom membership provider this will cause the job to run very slow. The PrincipalInfo of the users is fetched for all users. The method GetUser will be called for all users in the membership provider. <br />Some small changes to the code will fix this issue. Just check if the profile does subscribe to more than zero pages.</p> <div style="border-bottom: silver 1px solid; text-align: left; border-left: silver 1px solid; padding-bottom: 4px; line-height: 12pt;

I have been able to get rid of many deadlocks but not all.</p> <p>The profiles are fetched in blocks of 1000 in the subscription job. Between every 1000 some work is done for sending subscription emails to the users. This takes some time. For the next 1000 users it can be a deadlock. I think this occurs if a new user have registered during this time.</p> <p>I tried to increase the pageSize for the methodProfileManager.GetAllProfiles() to decrease the time between the first and the last profile. The deadlocks are almost gone. Is there any reason why EPiServer do this job in page sizes of 1000?

Here is my contribution to the contest. The users statistics gadget.</p> <p>It simply displays a chart with the number of users and subscription users you have registered on the site. It’s also possible to show a chart of the users in a specific role. All settings is done in the Edit menu.</p> <p>The chart is created in SIlverlight (<a href="http://visifire.com/" target="_blank">Visifire</a>). The Silverlight application accesses the users statistics from a WCF service. All wcf configurations is in the Gadget web.config. And therefore no need to update the web project’s web.config.</p> <p><a href="/link/6f5ebc4507734b12816667726027d552.png"><img style="BORDER-RIGHT-WIDTH: 0px; DISPLAY: inline; BORDER-TOP-WIDTH: 0px; BORDER-BOTTOM-WIDTH: 0px; BORDER-LEFT-WIDTH: 0px" title="image" border="0" alt="image" src="/link/db131a8070114cd2b50e9271f4795975.png" width="361" height="362" /></a>&nbsp;</p> <p>&nbsp;</p> <h1></h1> <h2>Configuration</h2> <p>By clicking the Edit in the menu you will see some configuration options. You can choose to show statistics for one role of all roles in the RoleMembershipProvider.</p> <p><a href="/link/06895f5775044e98afcc3f9f952c5f30.png"><img style="BORDER-RIGHT-WIDTH: 0px; DISPLAY: inline; BORDER-TOP-WIDTH: 0px; BORDER-BOTTOM-WIDTH: 0px; BORDER-LEFT-WIDTH: 0px" title="image" border="0" alt="image" src="/link/dda4fe13af8c477486ad9db6c0e174ec.png" width="362" height="371" /></a> </p> <h2>Save history data</h2> <p>The history data is stored in the DynamicDataStore. I have created a scheduled job which should be executed once a day. </p> <p>As seen in the image above I have made it possible to generate dummy data for the statistics. This is just for demo purposes.</p> <h2>Installation</h2> <p>If you have problems with the Silverlight chart. Add mime type to IIS: .xap&nbsp;&nbsp;&nbsp;&nbsp; application/x-silverlight-app. <a href="http://learn.iis.net/page.aspx/262/configuring-iis-for-silverlight-applications/" target="_blank">Configuring IIS for Silverlight Applications</a>.</p> <p>The clientaccesspolicy.xml must be placed in the root of your project to get the Silverlight wcf reference running. This is done by the installer below.</p> <div style="PADDING-BOTTOM: 0px; MARGIN: 0px; PADDING-LEFT: 0px; PADDING-RIGHT: 0px; DISPLAY: inline; FLOAT: none; PADDING-TOP: 0px" id="scid:12CF4F9E-00D5-4d59-A727-42B7641FBD93:96653902-0650-4dbe-9efd-61a5c6906761" class="wlWriterEditableSmartContent"> <div>Download <a href="/link/6a4916ebc01b4c9a805f4bd10c11a088.zip" target="_blank">UsersStatistics</a></div></div> <h2>Source code</h2> <div style="PADDING-BOTTOM: 0px; MARGIN: 0px; PADDING-LEFT: 0px; PADDING-RIGHT: 0px; DISPLAY: inline; FLOAT: none; PADDING-TOP: 0px" id="scid:12CF4F9E-00D5-4d59-A727-42B7641FBD93:238bdecb-cc7d-441a-9fb1-2bb3cdfad4b4" class="wlWriterEditableSmartContent"> <div>Download <a href="/link/db76a11cb8df45f9bc99870045464f44.zip" target="_blank">UsersStatistics</a></div></div>2009-11-07T23:59:00.0000000ZBlog post EPiServer Community and user attributes<p>This article will give some examples of how to work with attributes on users in the EPiServer Community. Attributes can also be used on other objects in the commnuity, such as blogs, but this will not be discussed here.</p> <h3>Adding attributes</h3> <p>To get it possible to work with an attribute, you must first add it. Click on the Attributes link in the Community tab. You will get this dialog:</p> <p><a href="/link/5b283aad53a64110ba2ff382f2036fcf.png"><img title="image" style="border-top-width: 0px; display: inline; border-left-width: 0px; border-bottom-width: 0px; border-right-width: 0px" height="183" alt="image" src="/link/a09f492005384d8782771aaac5ff9b7d.png" width="446" border="0" /></a> </p> <p>I will here create an attribute “ServiceIdentifier” of type string for the IUser class. It will now be possible to set this attribute on all users.</p> <p><a href="/link/4a42f43831894a5c81115c04e327a58c.png"><img title="image" style="border-top-width: 0px; display: inline; border-left-width: 0px; border-bottom-width: 0px; border-right-width: 0px" height="274" alt="image" src="/link/688bcb6963684ba0947d7297ffb22761.png" width="430" border="0" /></a> </p> <p>It is also possible to create custom attribute types. You can read about it here: <a title="http://world.episerver.com/en/Articles/Items/Creating-a-Custom-EPiServer-Community-Module---Attribute-Data-Types/" href="http://world.episerver.com/en/Articles/Items/Creating-a-Custom-EPiServer-Community-Module---Attribute-Data-Types/">http://world.episerver.com/en/Articles/Items/Creating-a-Custom-EPiServer-Community-Module---Attribute-Data-Types/</a></p> <h3>Set attribute value on the user</h3> <p>I will here set a guid to this newly created attribute.

Just comment this line and the application will start. I don't' know what this handler does but probably ImageVault will come up with a solution soon.</p>2009-05-12T09:04:36.1300000ZBlog post Silverlight + EPiServerFör ett tag sedan lanserade vi en site gjord i Silverlight och EPiServer CMS 5 R2. Det fungerar mycket bra och vi har gjort en hel del smarta funktioner för att hämta och spara data i EPiServer.<br /><br />Lösningen som är lite av ett Community använder mycket personalisering i .NET. Silverlight har fullt stöd för .Net profiles, authorization och authentication via WCF (Windows Communication Foundation). Detta är helt grymt bra och lätt att jobba med.<br /><br />Kanske kommer det lite mer information om siten i fråga vid ett senare tillfälle.2009-03-10T13:45:00.0000000ZBlog post EPiServer Scheduled jobs not working - solutionHi<br /><br />You may get an error like this: Object reference not set to an instance of an object in your scheduled job. This only occurs when executing the job as scheduled, not manually.<br /><br />I had big problems with this and found the solution.<br />The HttpContext.Current is null when running the job scheduled.<br /><br />I'm using HttpContext.Current.Cache a lot when caching data in .Net. E.g. when reading from a file I usully place it in the cache with a CacheDependency attached to it.<br /><br /><strong>Example:</strong> (Does not work in EPiServer scheduled jobs)<br />public static XDocument AreaExtraItemXDocument<br />{<br />get<br />{<br />XDocument areaExtraItemXpath = (XDocument)HttpContext.Current.Cache["CacheKey"];<br />if (areaExtraItemXpath == null)<br />{<br />string xmlPath = "c:\file.xml";<br />if (File.Exists(xmlPath))<br />{<br />CacheDependency cacheDep = new CacheDependency(xmlPath);<br />areaExtraItemXpath = XDocument.Load(xmlPath);<br />HttpContext.Current.Cache.Insert("CacheKey", areaExtraItemXpath, cacheDep);<br />}<br />}<br />return areaExtraItemXpath;<br />}<br />}<br /><br /><strong>Solution:</strong><br /><br />public static XDocument AreaExtraItemXDocument<br />{<br />get<br />{<br />XDocument areaExtraItemXpath = null;<br />if (HttpContext.Current == null HttpContext.Current.Cache["CacheKey"] == null)<br />{<br />string xmlPath = "c:\file.xml";<br />if (File.Exists(xmlPath))<br />{<br />areaExtraItemXpath = XDocument.Load(xmlPath);<br />if (HttpContext.Current != null)<br />{<br />CacheDependency cacheDep = new CacheDependency(xmlPath);<br />HttpContext.Current.Cache.Insert("CacheKey", areaExtraItemXpath, cacheDep);<br />}<br />}<br />}<br />else<br />{<br />areaExtraItemXpath = (XDocument)HttpContext.Current.Cache["CacheKey"];<br />}<br />return areaExtraItemXpath;<br />}<br />}2009-02-10T13:27:00.0000000ZBlog post SSL redirect komponentJag har på en site haft behovet att redirecta mellan http och https och vice versa. Detta gäller på vissa sidor som innehåller känslig information för den inloggade användaren, tex personnummer. Kravet har då varit att det alltid måste vara https på känsliga sidor och http på övriga sidor. En lösning kan ju vara att köra https på alla sidor på siten, men det ökar trafiken väsentligt om bara en liten del av siten egentligen behöver https.<br /><br />Det finns vissa lösningar med javascript och en redirect.htm. Dock så har denna metod inte fungerat med EPiServers friendly url rewriter.<br />Lösningen var detta projekt som sköter allt det jag vill: <a href="http://www.codeproject.com/KB/web-security/WebPageSecurity_v2.aspx">http://www.codeproject.com/KB/web-security/WebPageSecurity_v2.aspx</a><br /><br />Man kan även göra alla inställningar om vilka sidor som ska vara säkra och inte i web.config, vilket är väldigt smidigt.<br /><br />Har man ISA-server så måste en del inställningar göras, enligt denna: <a href="http://goatly.spaces.live.com/blog/cns!ED869F22AB5C24A8!267.entry">http://goatly.spaces.live.com/blog/cns!ED869F22AB5C24A8!267.entry</a>2009-01-29T15:15:00.0000000ZBlog post EPiServer CMS Certified DeveloperYesterday, I passed the certification for EPiServer CMS 5. The test was quiet easy and my final result was 85%.2009-01-28T10:48:00.0000000ZBlog post EPiServer CMS 5 R2 and 4 on the same serverI thought EPiServer CMS R2 wouldn't work on the same server as EPiServer 4. The problem was the scheduler that did not work on the EPiServer 4 site. After some testing this was not the case. Se old blog post below.<br /><br />The solution is to follow this: <a href="/link/2acac8fbf8cb4884a84bc2d48b22104e.aspx">http://world.episerver.com/en/FAQ/Items/Running-the-scheduler-on-machines-with-both-EPiServer-CMS-4-and-5-installations/</a><br />Use version 5.1.422.4, not 5.1.422.172. It seems odd, but EPiServers scheduler in R2 uses the 5.1.422.4 version.<br /><br />Also check this if you have problems that the jobs i not executed: <a href="/link/669556c5febd41a090869b4d26cbb1e4.aspx">http://world.episerver.com/FAQ/Items/Scheduler-does-not-run-scheduled-jobs-automatically/</a><br />You can found the xml file here: C:\Program Files\EPiServer\Shared\Services\Scheduler Service<br /><br />Old post:<br /><em>Today I encoutered a huge problem with EPiServer.<br />You can't have EPiServer CMS 5 R2 and EPiServer 4 on the same production server. The reason is the EPiServer scheduler. R2 has a new scheduler which is not compatible with EPiServer 4.<br />When you install the installation package for R2, it will uninstall the old scheduler. Very bad.<br /><br />To get the EPiServer 4 scheduler back to work you have to do the following:<br />- Uninstall "EPiServer Shared"<br />- Install an EPiServer 4 site from EPiServer Manager. This will install the scheduler service again.<br /><br />If you are running EPiServer CMS 5 R1 and EPiServer 4 on the same server. These two versions does work together with some tweaks.

The user is not associated with a trusted SQL Server connection</strong><br /><strong></strong><br />I think the problem is that EPiServer Manager does not deal with integrated security.<br />The solution for me was to create an SQL user and change the Web.config to connect to the SQL database with this user.

I senaste EPiServer-versionen är det riktigt enkelt att få igång, speciellt om man kör .Net 3.5 där Microsofts AJAX-ramverk är inbyggt.<br /><br /><br /><br /><br />Det enda man behöver göra är att starta upp EPiServer-projektet i Visual Studio 2008 och sedan välja att köra med framwork .Net 3.5.
