• Easy Made Easier

  - by dragonfly

      How easy is it to deploy a 2 node, fully redundant Oracle RAC cluster? Not very. Unless you use an Oracle Database Appliance. The focus of this member of Oracle's Engineered Systems family is to simplify the configuration, management and maintenance throughout the life of the system, while offering pay-as-you-grow scaling. Getting a 2-node RAC cluster up and running in under 2 hours has been made possible by the Oracle Database Appliance. Don't take my word for it, just check out these blog posts from partners and end users. The Oracle Database Appliance Experience - Zip Zoom Zoom http://www.fuadarshad.com/2012/02/oracle-database-appliance-experience.html Off-the-shelf Oracle database servers http://normanweaver.wordpress.com/2011/10/10/off-the-shelf-oracle-database-servers/ Oracle Database Appliance – Deployment Steps http://marcel.vandewaters.nl/oracle/database-appliance/oracle-database-appliance-deployment-steps     See how easy it is to deploy an Oracle Database Appliance for high availability with RAC? Now for the meat of this post, which is the first in a series of posts describing tips for making the deployment of an ODA even easier. The key to the easy deployment of an Oracle Database Appliance is the Appliance Manager software, which does the actual software deployment and configuration, based on best practices. But in order for it to do that, it needs some basic information first, including system name, IP addresses, etc. That's where the Appliance Manager GUI comes in to play, taking a wizard approach to specifying the information needed.     Using the Appliance Manager GUI is pretty straight forward, stepping through several screens of information to enter data in typical wizard style. Like most configuration tasks, it helps to gather the required information before hand. But before you rush out to a committee meeting on what to use for host names, and rely on whatever IP addresses might be hanging around, make sure you are familiar with some of the auto-fill defaults for the Appliance Manager. I'll step through the key screens below to highlight the results of the auto-fill capability of the Appliance Manager GUI.     Depending on which of the 2 Configuration Types (Config Type screen) you choose, you will get a slightly different set of screens. The Typical configuration assumes certain default configuration choices and has the fewest screens, where as the Custom configuration gives you the most flexibility in what you configure from the start. In the examples below, I have used the Custom config type.     One of the first items you are asked for is the System Name (System Info screen). This is used to identify the system, but also as the base for the default hostnames on following screens. In this screen shot, the System Name is "oda".     When you get to the next screen (Generic Network screen), you enter your domain name, DNS IP address(es), and NTP IP address(es). Next up is the Public Network screen, seen below, where you will see the host name fields are automatically filled in with default host names based on the System Name, in this case "oda". The System Name is also the basis for default host names for the extra ethernet ports available for configuration as part of a Custom configuration, as seen in the 2nd screen shot below (Other Network). There is no requirement to use these host names, as you can easily edit any of the host names. This does make filling in the configuration details easier and less prone to "fat fingers" if you are OK with these host names. Here is a full list of the automatically filled in host names. 1 2 1-vip 2-vip -scan 1-ilom 2-ilom 1-net1 2-net1 1-net2 2-net2 1-net3 2-net3     Another auto-fill feature of the Appliance Manager GUI follows a common practice of deploying IP Addresses for a RAC cluster in sequential order. In the screen shot below, I entered the first IP address (Node1-IP), then hit Tab to move to the next field. As a result, the next 5 IP address fields were automatically filled in with the next 5 IP addresses sequentially from the first one I entered. As with the host names, these are not required, and can be changed to whatever your IP address values are. One note of caution though, if the first IP Address field (Node1-IP) is filled out and you click in that field and back out, the following 5 IP addresses will be set to the sequential default. If you don't use the sequential IP addresses, pay attention to where you click that mouse. :-)     In the screen shot below, by entering the netmask value in the Netmask field, in this case 255.255.255.0, the gateway value was auto-filled into the Gateway field, based on the IP addresses and netmask previously entered. As always, you can change this value.     My last 2 screen shots illustrate that the same sequential IP address autofill and netmask to gateway autofill works when entering the IP configuration details for the Integrated Lights Out Manager (ILOM) for both nodes. The time these auto-fill capabilities save in entering data is nice, but from my perspective not as important as the opportunity to avoid data entry errors. In my next post in this series, I will touch on the benefit of using the network validation capability of the Appliance Manager GUI prior to deploying an Oracle Database Appliance.

• iPhone doesn't save password for Cisco IPsec VPN using racoon daemon

  - by dsx

  On my Debian server I had set up racoon daemon (1:0.8.0-14) for Cisco IPSec VPN using certificates for authentication. My racoon.conf is like following: log info; path certificate "/etc/racoon/certs"; listen { isakmp $SERVER_IP_HERE [500]; isakmp_natt $SERVER_IP_HERE [4500]; } timer { natt_keepalive 10 sec; } remote anonymous { lifetime time 24 hours; proposal_check obey; passive on; exchange_mode aggressive,main; my_identifier asn1dn; peers_identifier asn1dn; verify_identifier on; certificate_type x509 "cert_name.crt" "key_name.key"; ca_type x509 "ca.crt"; mode_cfg on; verify_cert on; ike_frag on; generate_policy on; nat_traversal on; dpd_delay 20; proposal { encryption_algorithm aes; hash_algorithm sha1; authentication_method xauth_rsa_server; dh_group modp1024; } } mode_cfg { conf_source local; auth_source system; auth_throttle 3; save_passwd on; dns4 8.8.8.8; network4 $SOME_LAN_SUBNET; netmask4 255.255.255.0; pool_size 128; } sainfo anonymous { pfs_group 2; lifetime time 24 hour; encryption_algorithm aes; authentication_algorithm hmac_sha1; compression_algorithm deflate; } I'm not using PSK authentication here. Using iPhone configuration utility I had uploaded all required certificates to iPhone and set up VPN on demand. Everything works just fine except one thing: iPhone refuses to save VPN password regardless of save_passwd on; in racoon configuration file. As opposed to iPhone behaviour, Mac OS X 10.8.2 have no problems saving password. I had examined iPhone log file and found following: racoon[151] <Notice>: >>>>> phase change status = phase 1 established configd[50] <Notice>: IPSec Network Configuration started. configd[50] <Notice>: IPSec Network Configuration: INTERNAL-IP4-ADDRESS = $SUBNET_IP_HERE. configd[50] <Notice>: IPSec Network Configuration: INTERNAL-IP4-MASK = 255.255.255.0. configd[50] <Notice>: IPSec Network Configuration: SAVE-PASSWORD = 0. configd[50] <Notice>: IPSec Network Configuration: INTERNAL-IP4-DNS = 8.8.8.8. configd[50] <Notice>: IPSec Network Configuration: BANNER = . configd[50] <Notice>: IPSec Network Configuration: DEF-DOMAIN = . configd[50] <Notice>: IPSec Network Configuration: DEFAULT-ROUTE = local-address $SUBNET_IP_HERE/32. configd[50] <Notice>: IPSec Phase2 starting. configd[50] <Notice>: IPSec Network Configuration established. configd[50] <Notice>: IPSec Phase1 established. Please note IPSec Network Configuration message containing SAVE-PASSWORD = 0.. Is it a bug in racoon daemon on server, or iPhone (iOS version is 6.0.1 (10A523)) or it is me missing something? How to make iPhone remember IPSec VPN password?

• What’s new in ASP.NET 4.0: Core Features

  - by Rick Strahl

  Microsoft released the .NET Runtime 4.0 and with it comes a brand spanking new version of ASP.NET – version 4.0 – which provides an incremental set of improvements to an already powerful platform. .NET 4.0 is a full release of the .NET Framework, unlike version 3.5, which was merely a set of library updates on top of the .NET Framework version 2.0. Because of this full framework revision, there has been a welcome bit of consolidation of assemblies and configuration settings. The full runtime version change to 4.0 also means that you have to explicitly pick version 4.0 of the runtime when you create a new Application Pool in IIS, unlike .NET 3.5, which actually requires version 2.0 of the runtime. In this first of two parts I'll take a look at some of the changes in the core ASP.NET runtime. In the next edition I'll go over improvements in Web Forms and Visual Studio. Core Engine Features Most of the high profile improvements in ASP.NET have to do with Web Forms, but there are a few gems in the core runtime that should make life easier for ASP.NET developers. The following list describes some of the things I've found useful among the new features. Clean web.config Files Are Back! If you've been using ASP.NET 3.5, you probably have noticed that the web.config file has turned into quite a mess of configuration settings between all the custom handler and module mappings for the various web server versions. Part of the reason for this mess is that .NET 3.5 is a collection of add-on components running on top of the .NET Runtime 2.0 and so almost all of the new features of .NET 3.5 where essentially introduced as custom modules and handlers that had to be explicitly configured in the config file. Because the core runtime didn't rev with 3.5, all those configuration options couldn't be moved up to other configuration files in the system chain. With version 4.0 a consolidation was possible, and the result is a much simpler web.config file by default. A default empty ASP.NET 4.0 Web Forms project looks like this: <?xml version="1.0"?> <configuration> <system.web> <compilation debug="true" targetFramework="4.0" /> </system.web> </configuration> Need I say more? Configuration Transformation Files to Manage Configurations and Application Packaging ASP.NET 4.0 introduces the ability to create multi-target configuration files. This means it's possible to create a single configuration file that can be transformed based on relatively simple replacement rules using a Visual Studio and WebDeploy provided XSLT syntax. The idea is that you can create a 'master' configuration file and then create customized versions of this master configuration file by applying some relatively simplistic search and replace, add or remove logic to specific elements and attributes in the original file. To give you an idea, here's the example code that Visual Studio creates for a default web.Release.config file, which replaces a connection string, removes the debug attribute and replaces the CustomErrors section: <?xml version="1.0"?> <configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform"> <connectionStrings> <add name="MyDB" connectionString="Data Source=ReleaseSQLServer;Initial Catalog=MyReleaseDB;Integrated Security=True" xdt:Transform="SetAttributes" xdt:Locator="Match(name)"/> </connectionStrings> <system.web> <compilation xdt:Transform="RemoveAttributes(debug)" /> <customErrors defaultRedirect="GenericError.htm" mode="RemoteOnly" xdt:Transform="Replace"> <error statusCode="500" redirect="InternalError.htm"/> </customErrors> </system.web> </configuration> You can see the XSL transform syntax that drives this functionality. Basically, only the elements listed in the override file are matched and updated – all the rest of the original web.config file stays intact. Visual Studio 2010 supports this functionality directly in the project system so it's easy to create and maintain these customized configurations in the project tree. Once you're ready to publish your application, you can then use the Publish <yourWebApplication> option on the Build menu which allows publishing to disk, via FTP or to a Web Server using Web Deploy. You can also create a deployment package as a .zip file which can be used by the WebDeploy tool to configure and install the application. You can manually run the Web Deploy tool or use the IIS Manager to install the package on the server or other machine. You can find out more about WebDeploy and Packaging here: http://tinyurl.com/2anxcje. Improved Routing Routing provides a relatively simple way to create clean URLs with ASP.NET by associating a template URL path and routing it to a specific ASP.NET HttpHandler. Microsoft first introduced routing with ASP.NET MVC and then they integrated routing with a basic implementation in the core ASP.NET engine via a separate ASP.NET routing assembly. In ASP.NET 4.0, the process of using routing functionality gets a bit easier. First, routing is now rolled directly into System.Web, so no extra assembly reference is required in your projects to use routing. The RouteCollection class now includes a MapPageRoute() method that makes it easy to route to any ASP.NET Page requests without first having to implement an IRouteHandler implementation. It would have been nice if this could have been extended to serve *any* handler implementation, but unfortunately for anything but a Page derived handlers you still will have to implement a custom IRouteHandler implementation. ASP.NET Pages now include a RouteData collection that will contain route information. Retrieving route data is now a lot easier by simply using this.RouteData.Values["routeKey"] where the routeKey is the value specified in the route template (i.e., "users/{userId}" would use Values["userId"]). The Page class also has a GetRouteUrl() method that you can use to create URLs with route data values rather than hardcoding the URL: <%= this.GetRouteUrl("users",new { userId="ricks" }) %> You can also use the new Expression syntax using <%$RouteUrl %> to accomplish something similar, which can be easier to embed into Page or MVC View code: <a runat="server" href='<%$RouteUrl:RouteName=user, id=ricks %>'>Visit User</a> Finally, the Response object also includes a new RedirectToRoute() method to build a route url for redirection without hardcoding the URL. Response.RedirectToRoute("users", new { userId = "ricks" }); All of these routines are helpers that have been integrated into the core ASP.NET engine to make it easier to create routes and retrieve route data, which hopefully will result in more people taking advantage of routing in ASP.NET. To find out more about the routing improvements you can check out Dan Maharry's blog which has a couple of nice blog entries on this subject: http://tinyurl.com/37trutj and http://tinyurl.com/39tt5w5. Session State Improvements Session state is an often used and abused feature in ASP.NET and version 4.0 introduces a few enhancements geared towards making session state more efficient and to minimize at least some of the ill effects of overuse. The first improvement affects out of process session state, which is typically used in web farm environments or for sites that store application sensitive data that must survive AppDomain restarts (which in my opinion is just about any application). When using OutOfProc session state, ASP.NET serializes all the data in the session statebag into a blob that gets carried over the network and stored either in the State server or SQL Server via the Session provider. Version 4.0 provides some improvement in this serialization of the session data by offering an enableCompression option on the web.Config <Session> section, which forces the serialized session state to be compressed. Depending on the type of data that is being serialized, this compression can reduce the size of the data travelling over the wire by as much as a third. It works best on string data, but can also reduce the size of binary data. In addition, ASP.NET 4.0 now offers a way to programmatically turn session state on or off as part of the request processing queue. In prior versions, the only way to specify whether session state is available is by implementing a marker interface on the HTTP handler implementation. In ASP.NET 4.0, you can now turn session state on and off programmatically via HttpContext.Current.SetSessionStateBehavior() as part of the ASP.NET module pipeline processing as long as it occurs before the AquireRequestState pipeline event. Output Cache Provider Output caching in ASP.NET has been a very useful but potentially memory intensive feature. The default OutputCache mechanism works through in-memory storage that persists generated output based on various lifetime related parameters. While this works well enough for many intended scenarios, it also can quickly cause runaway memory consumption as the cache fills up and serves many variations of pages on your site. ASP.NET 4.0 introduces a provider model for the OutputCache module so it becomes possible to plug-in custom storage strategies for cached pages. One of the goals also appears to be to consolidate some of the different cache storage mechanisms used in .NET in general to a generic Windows AppFabric framework in the future, so various different mechanisms like OutputCache, the non-Page specific ASP.NET cache and possibly even session state eventually can use the same caching engine for storage of persisted data both in memory and out of process scenarios. For developers, the OutputCache provider feature means that you can now extend caching on your own by implementing a custom Cache provider based on the System.Web.Caching.OutputCacheProvider class. You can find more info on creating an Output Cache provider in Gunnar Peipman's blog at: http://tinyurl.com/2vt6g7l. Response.RedirectPermanent ASP.NET 4.0 includes features to issue a permanent redirect that issues as an HTTP 301 Moved Permanently response rather than the standard 302 Redirect respond. In pre-4.0 versions you had to manually create your permanent redirect by setting the Status and Status code properties – Response.RedirectPermanent() makes this operation more obvious and discoverable. There's also a Response.RedirectToRoutePermanent() which provides permanent redirection of route Urls. Preloading of Applications ASP.NET 4.0 provides a new feature to preload ASP.NET applications on startup, which is meant to provide a more consistent startup experience. If your application has a lengthy startup cycle it can appear very slow to serve data to clients while the application is warming up and loading initial resources. So rather than serve these startup requests slowly in ASP.NET 4.0, you can force the application to initialize itself first before even accepting requests for processing. This feature works only on IIS 7.5 (Windows 7 and Windows Server 2008 R2) and works in combination with IIS. You can set up a worker process in IIS 7.5 to always be running, which starts the Application Pool worker process immediately. ASP.NET 4.0 then allows you to specify site-specific settings by setting the serverAutoStartEnabled on a particular site along with an optional serviceAutoStartProvider class that can be used to receive "startup events" when the application starts up. This event in turn can be used to configure the application and optionally pre-load cache data and other information required by the app on startup.  The configuration settings need to be made in applicationhost.config: <sites> <site name="WebApplication2" id="1"> <application path="/" serviceAutoStartEnabled="true" serviceAutoStartProvider="PreWarmup" /> </site> </sites> <serviceAutoStartProviders> <add name="PreWarmup" type="PreWarmupProvider,MyAssembly" /> </serviceAutoStartProviders> Hooking up a warm up provider is optional so you can omit the provider definition and reference. If you do define it here's what it looks like: public class PreWarmupProvider System.Web.Hosting.IProcessHostPreloadClient { public void Preload(string[] parameters) { // initialization for app } } This code fires and while it's running, ASP.NET/IIS will hold requests from hitting the pipeline. So until this code completes the application will not start taking requests. The idea is that you can perform any pre-loading of resources and cache values so that the first request will be ready to perform at optimal performance level without lag. Runtime Performance Improvements According to Microsoft, there have also been a number of invisible performance improvements in the internals of the ASP.NET runtime that should make ASP.NET 4.0 applications run more efficiently and use less resources. These features come without any change requirements in applications and are virtually transparent, except that you get the benefits by updating to ASP.NET 4.0. Summary The core feature set changes are minimal which continues a tradition of small incremental changes to the ASP.NET runtime. ASP.NET has been proven as a solid platform and I'm actually rather happy to see that most of the effort in this release went into stability, performance and usability improvements rather than a massive amount of new features. The new functionality added in 4.0 is minimal but very useful. A lot of people are still running pure .NET 2.0 applications these days and have stayed off of .NET 3.5 for some time now. I think that version 4.0 with its full .NET runtime rev and assembly and configuration consolidation will make an attractive platform for developers to update to. If you're a Web Forms developer in particular, ASP.NET 4.0 includes a host of new features in the Web Forms engine that are significant enough to warrant a quick move to .NET 4.0. I'll cover those changes in my next column. Until then, I suggest you give ASP.NET 4.0 a spin and see for yourself how the new features can help you out. © Rick Strahl, West Wind Technologies, 2005-2010Posted in ASP.NET

• Performance issues with jms and spring integration. What is wrong with the following configuration?

  - by user358448

  I have a jms producer, which generates many messages per second, which are sent to amq persistent queue and are consumed by single consumer, which needs to process them sequentially. But it seems that the producer is much faster than the consumer and i am having performance and memory problems. Messages are fetched very very slowly and the consuming seems to happen on intervals (the consumer "asks" for messages in polling fashion, which is strange?!) Basically everything happens with spring integration. Here is the configuration at the producer side. First stake messages come in stakesInMemoryChannel, from there, they are filtered throw the filteredStakesChannel and from there they are going into the jms queue (using executor so the sending will happen in separate thread) <bean id="stakesQueue" class="org.apache.activemq.command.ActiveMQQueue"> <constructor-arg name="name" value="${jms.stakes.queue.name}" /> </bean> <int:channel id="stakesInMemoryChannel" /> <int:channel id="filteredStakesChannel" > <int:dispatcher task-executor="taskExecutor"/> </int:channel> <bean id="stakeFilterService" class="cayetano.games.stake.StakeFilterService"/> <int:filter input-channel="stakesInMemoryChannel" output-channel="filteredStakesChannel" throw-exception-on-rejection="false" expression="true"/> <jms:outbound-channel-adapter channel="filteredStakesChannel" destination="stakesQueue" delivery-persistent="true" explicit-qos-enabled="true" /> <task:executor id="taskExecutor" pool-size="100" /> The other application is consuming the messages like this... The messages come in stakesInputChannel from the jms stakesQueue, after that they are routed to 2 separate channels, one persists the message and the other do some other stuff, lets call it "processing". <bean id="stakesQueue" class="org.apache.activemq.command.ActiveMQQueue"> <constructor-arg name="name" value="${jms.stakes.queue.name}" /> </bean> <jms:message-driven-channel-adapter channel="stakesInputChannel" destination="stakesQueue" acknowledge="auto" concurrent-consumers="1" max-concurrent-consumers="1" /> <int:publish-subscribe-channel id="stakesInputChannel" /> <int:channel id="persistStakesChannel" /> <int:channel id="processStakesChannel" /> <int:recipient-list-router id="customRouter" input-channel="stakesInputChannel" timeout="3000" ignore-send-failures="true" apply-sequence="true" > <int:recipient channel="persistStakesChannel"/> <int:recipient channel="processStakesChannel"/> </int:recipient-list-router> <bean id="prefetchPolicy" class="org.apache.activemq.ActiveMQPrefetchPolicy"> <property name="queuePrefetch" value="${jms.broker.prefetch.policy}" /> </bean> <bean id="connectionFactory" class="org.springframework.jms.connection.CachingConnectionFactory"> <property name="targetConnectionFactory"> <bean class="org.apache.activemq.ActiveMQConnectionFactory"> <property name="brokerURL" value="${jms.broker.url}" /> <property name="prefetchPolicy" ref="prefetchPolicy" /> <property name="optimizeAcknowledge" value="true" /> <property name="useAsyncSend" value="true" /> </bean> </property> <property name="sessionCacheSize" value="10"/> <property name="cacheProducers" value="false"/> </bean>

• Getting Started with Media Browser for Windows Media Center

  - by DigitalGeekery

  If you are a Windows Media Center user, you’ll really want to check out Media Browser. The Media Browser plug-in for Windows Media Center takes your digital media files and displays them in a visually appealing, user friendly interface, complete with images and metadata. Requirements Windows 7 or Vista Microsoft .Net 3.5 Framework  Preparing your Media Files For Media Browser to be able to automatically download images and metadata for your media libraries, your files will have to be correctly named. For example, if you have an mp4 file of the movie Batman Begins, it needs to be named Batman Begins.mp4. It cannot be Batmanbegins.mp4 or Batman-begins.mp4. Otherwise, it’s unlikely that Media Browser will display images and metadata. If you find some of your files aren’t pulling cover art or metadata, double-check the official title of the media on a site like IMBD.com. TV Show files TV show files are handled a bit differently. Every TV series in your collection must have a main folder with the show’s name and individual subfolders for each season. Here is an example of folder structure and supported naming conventions. TV Shows\South Park\Season 1\s01e01 – episode 1.mp4 TV Shows\South Park\Season 1\South Park 1×01 – episode 1.mp4 TV Shows\South Park\Season 1\101 – episode 1.mp4  Note: You need to always have a Season 1 folder even if the show only has only one season. If you have several seasons of a particular show, but don’t happen to have Season 1, simply create a blank season 1 folder. Without a season 1 folder, other seasons will not display properly. Installation and Configuration Download and run the latest Media Browser .msi file by taking the defaults. (Download link below) When you reach the final window, leave the “Configure initial settings” box checked, and click “Finish.” You may get a pop up window informing you that folder permissions are not set correctly for Media Browser. Click “Yes.” Adding Your Media The Browser Configuration Tool should have opened automatically. If not, you can open it by going to Start > All Programs > Media Browser > Media Browser Configuration Wizard. To begin adding media files, click “Add.” Browse for a folder that contains media files and click “OK.” Here we are adding a folder with a group of movie files. You can add multiple folders to each media library. For example, if you have movie files stored in 4 or 5 different folders, you can add them all under a single library in Media Browser.  To add additional folders, click the “Add” button on the right side under your currently added folder. The “Add” button to the left will add an additional Media Library, such as one for TV Shows. When you are finished, close out of the Media Browser Configuration Tool. Open Windows Media Center. You will see Media Browser tile on the main interface. Click to open it. When you initially open Media Browser, you will be prompted to run the initial configuration. Click “OK.” You will see a few general configuration options. The important option is the Metadata. Leave this option checked (it is by default) if you wish to pull images & other metadata for your media. When finished, click “Continue,” and then “OK” to restart Media Browser. When you re-enter Media Browser you’ll see your Media Categories listed below, and recently added files in the main display. Click on a Media Library to view the files.   Click “View” at the top to check out some of the different display options to choose from. Below you see can “Detail.” This presents your videos in a list to the left. When you hover over a title, the synopsis and cover art is displayed to the right. “Cover Flow” displays your titles in a right to left format with mirror cover art. “Thumb Strip” displays your titles in a strip along the bottom with a synopsis, image, and movie data above. Configurations Settings and options can be changed through the Media Browser Configuration Tool, or directly in Media Browser by clicking on the “Wrench” at the bottom right of the main Media Browser page. Certain settings may only be available in one location or the other.

• Getting started with Blocks and namespaces - Enterprise Library 5.0 Tutorial Part 2

  This is my second post in this series. In first blog post I explained how to install Enterprise Library 5.0 and provided links to various resources. Enterprise Library is divided into various blocks. Simply we can say, a block is a ready made solution for a particular common problem across various applications. So instead focusing on implementation of common problem across various applications, we can reuse these fully tested and extendable blocks to increase the productivity and also extendibility as these blocks are made with good design principles and patterns. Major blocks of Enterprise Library 5.0 are as follows.   Core infrastructure Functional Application Blocks Caching Data Exception Handling Logging Security Cryptography Validation Wiring Application Blocks Unity Policy Injection/Interception   Each block resides in its own assembly, and also some extra assemblies for common infrastructure. Assemblies are as follows. Microsoft.Practices.EnterpriseLibrary.Caching.Cryptography.dll Microsoft.Practices.EnterpriseLibrary.Caching.Database.dll Microsoft.Practices.EnterpriseLibrary.Caching.dll Microsoft.Practices.EnterpriseLibrary.Common.dll Microsoft.Practices.EnterpriseLibrary.Configuration.Design.HostAdapter.dll Microsoft.Practices.EnterpriseLibrary.Configuration.Design.HostAdapterV5.dll Microsoft.Practices.EnterpriseLibrary.Configuration.DesignTime.dll Microsoft.Practices.EnterpriseLibrary.Configuration.EnvironmentalOverrides.dll Microsoft.Practices.EnterpriseLibrary.Data.dll Microsoft.Practices.EnterpriseLibrary.Data.SqlCe.dll Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.dll Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.Logging.dll Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.WCF.dll Microsoft.Practices.EnterpriseLibrary.Logging.Database.dll Microsoft.Practices.EnterpriseLibrary.Logging.dll Microsoft.Practices.EnterpriseLibrary.PolicyInjection.dll Microsoft.Practices.EnterpriseLibrary.Security.Cache.CachingStore.dll Microsoft.Practices.EnterpriseLibrary.Security.Cryptography.dll Microsoft.Practices.EnterpriseLibrary.Security.dll Microsoft.Practices.EnterpriseLibrary.Validation.dll Microsoft.Practices.EnterpriseLibrary.Validation.Integration.AspNet.dll Microsoft.Practices.EnterpriseLibrary.Validation.Integration.WCF.dll Microsoft.Practices.EnterpriseLibrary.Validation.Integration.WinForms.dll Microsoft.Practices.ServiceLocation.dll Microsoft.Practices.Unity.Configuration.dll Microsoft.Practices.Unity.dll Microsoft.Practices.Unity.Interception.dll Enterprise Library Configuration Tool In addition to these assemblies you would get configuration tool “EntLibConfig-32.exe”. If you are targeting your application to .NET 4.0 framework then you would need to use “EntLibConfig.NET4.exe”. Optionally you can install Visual Studio 2008 and Visual Studio 2010 add-ins whilst installing of Enterprise Library. So that you can invoke the enterprise Library configuration from Visual Studio by right clicking on “app.config” or “web.config” file as shown below. I would suggest you to download the documentation from Codeplex which was released on May 2010. It consists 3MB of information. you can also find issue tracker to know various issues/bugs currently people talking about enterprise library. There is also discussion link takes you to community site where you can post your questions. In my next blog post, I would cover more on each block. span.fullpost {display:none;}

• Setting up a VPN connection to Amazon VPC - routing

  - by Keeno

  I am having some real issues setting up a VPN between out office and AWS VPC. The "tunnels" appear to be up, however I don't know if they are configured correctly. The device I am using is a Netgear VPN Firewall - FVS336GV2 If you see in the attached config downloaded from VPC (#3 Tunnel Interface Configuration), it gives me some "inside" addresses for the tunnel. When setting up the IPsec tunnels do I use the inside tunnel IP's (e.g. 169.254.254.2/30) or do I use my internal network subnet (10.1.1.0/24) I have tried both, when I tried the local network (10.1.1.x) the tracert stops at the router. When I tried with the "inside" ips, the tracert to the amazon VPC (10.0.0.x) goes out over the internet. this all leads me to the next question, for this router, how do I set up stage #4, the static next hop? What are these seemingly random "inside" addresses and where did amazon generate them from? 169.254.254.x seems odd? With a device like this, is the VPN behind the firewall? I have tweaked any IP addresses below so that they are not "real". I am fully aware, this is probably badly worded. Please if there is any further info/screenshots that will help, let me know.

To limit the impact of this behavior, we recommend the following configuration on your Customer Gateway: - TCP MSS Adjustment : 1387 bytes - Clear Don't Fragment Bit : enabled - Fragmentation : Before encryption #3: Tunnel Interface Configuration Your Customer Gateway must be configured with a tunnel interface that is associated with the IPSec tunnel. All traffic transmitted to the tunnel interface is encrypted and transmitted to the Virtual Private Gateway. The Customer Gateway and Virtual Private Gateway each have two addresses that relate to this IPSec tunnel. Each contains an outside address, upon which encrypted traffic is exchanged. Each also contain an inside address associated with the tunnel interface. The Customer Gateway outside IP address was provided when the Customer Gateway was created. Changing the IP address requires the creation of a new Customer Gateway. The Customer Gateway inside IP address should be configured on your tunnel interface. Outside IP Addresses: - Customer Gateway : 217.33.22.33 - Virtual Private Gateway : 87.222.33.42 Inside IP Addresses - Customer Gateway : 169.254.254.2/30 - Virtual Private Gateway : 169.254.254.1/30 Configure your tunnel to fragment at the optimal size: - Tunnel interface MTU : 1436 bytes #4: Static Routing Configuration: To route traffic between your internal network and your VPC, you will need a static route added to your router.

The VGW will then send traffic towards your internal network over the tunnels. EDIT #1 After writing this post, I continued to fiddle and something started to work, just not very reliably. The local IPs to use when setting up the tunnels where indeed my network subnets. Which further confuses me over what these "inside" IP addresses are for. The problem is, results are not consistent what so ever. I can "sometimes" ping, I can "sometimes" RDP using the VPN. Sometimes, Tunnel 1 or Tunnel 2 can be up or down. When I came back into work today, Tunnel 1 was down, so I deleted it and re-created it from scratch. Now I cant ping anything, but Amazon AND the router are telling me tunnel 1/2 are fine. I guess the router/vpn hardware I have just isnt up to the job..... EDIT #2 Now Tunnel 1 is up, Tunnel 2 is down (I didn't change any settings) and I can ping/rdp again. EDIT #3 Screenshot of route table that the router has built up. Current state (tunnel 1 still up and going string, 2 is still down and wont re-connect)

• Adding and accessing custom sections in your C# App.config

  - by deadlydog

  So I recently thought I’d try using the app.config file to specify some data for my application (such as URLs) rather than hard-coding it into my app, which would require a recompile and redeploy of my app if one of our URLs changed.  By using the app.config it allows a user to just open up the .config file that sits beside their .exe file and edit the URLs right there and then re-run the app; no recompiling, no redeployment necessary. I spent a good few hours fighting with the app.config and looking at examples on Google before I was able to get things to work properly.  Most of the examples I found showed you how to pull a value from the app.config if you knew the specific key of the element you wanted to retrieve, but it took me a while to find a way to simply loop through all elements in a section, so I thought I would share my solutions here.   Simple and Easy The easiest way to use the app.config is to use the built-in types, such as NameValueSectionHandler.  For example, if we just wanted to add a list of database server urls to use in my app, we could do this in the app.config file like so: 1: <?xml version="1.0" encoding="utf-8" ?> 2: <configuration> 3: <configSections> 4: <section name="ConnectionManagerDatabaseServers" type="System.Configuration.NameValueSectionHandler" /> 5: </configSections> 6: <startup> 7: <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" /> 8: </startup> 9: <ConnectionManagerDatabaseServers> 10: <add key="localhost" value="localhost" /> 11: <add key="Dev" value="Dev.MyDomain.local" /> 12: <add key="Test" value="Test.MyDomain.local" /> 13: <add key="Live" value="Prod.MyDomain.com" /> 14: </ConnectionManagerDatabaseServers> 15: </configuration>   And then you can access these values in code like so: 1: string devUrl = string.Empty; 2: var connectionManagerDatabaseServers = ConfigurationManager.GetSection("ConnectionManagerDatabaseServers") as NameValueCollection; 3: if (connectionManagerDatabaseServers != null) 4: { 5: devUrl = connectionManagerDatabaseServers["Dev"].ToString(); 6: }   Sometimes though you don’t know what the keys are going to be and you just want to grab all of the values in that ConnectionManagerDatabaseServers section.  In that case you can get them all like this: 1: // Grab the Environments listed in the App.config and add them to our list. 2: var connectionManagerDatabaseServers = ConfigurationManager.GetSection("ConnectionManagerDatabaseServers") as NameValueCollection; 3: if (connectionManagerDatabaseServers != null) 4: { 5: foreach (var serverKey in connectionManagerDatabaseServers.AllKeys) 6: { 7: string serverValue = connectionManagerDatabaseServers.GetValues(serverKey).FirstOrDefault(); 8: AddDatabaseServer(serverValue); 9: } 10: }   And here we just assume that the AddDatabaseServer() function adds the given string to some list of strings.  So this works great, but what about when we want to bring in more values than just a single string (or technically you could use this to bring in 2 strings, where the “key” could be the other string you want to store; for example, we could have stored the value of the Key as the user-friendly name of the url).   More Advanced (and more complicated) So if you want to bring in more information than a string or two per object in the section, then you can no longer simply use the built-in System.Configuration.NameValueSectionHandler type provided for us.  Instead you have to build your own types.  Here let’s assume that we again want to configure a set of addresses (i.e. urls), but we want to specify some extra info with them, such as the user-friendly name, if they require SSL or not, and a list of security groups that are allowed to save changes made to these endpoints. So let’s start by looking at the app.config: 1: <?xml version="1.0" encoding="utf-8" ?> 2: <configuration> 3: <configSections> 4: <section name="ConnectionManagerDataSection" type="ConnectionManagerUpdater.Data.Configuration.ConnectionManagerDataSection, ConnectionManagerUpdater" /> 5: </configSections> 6: <startup> 7: <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" /> 8: </startup> 9: <ConnectionManagerDataSection> 10: <ConnectionManagerEndpoints> 11: <add name="Development" address="Dev.MyDomain.local" useSSL="false" /> 12: <add name="Test" address="Test.MyDomain.local" useSSL="true" /> 13: <add name="Live" address="Prod.MyDomain.com" useSSL="true" securityGroupsAllowedToSaveChanges="ConnectionManagerUsers" /> 14: </ConnectionManagerEndpoints> 15: </ConnectionManagerDataSection> 16: </configuration>   The first thing to notice here is that my section is now using the type “ConnectionManagerUpdater.Data.Configuration.ConnectionManagerDataSection” (the fully qualified path to my new class I created) “, ConnectionManagerUpdater” (the name of the assembly my new class is in).  Next, you will also notice an extra layer down in the <ConnectionManagerDataSection> which is the <ConnectionManagerEndpoints> element.  This is a new collection class that I created to hold each of the Endpoint entries that are defined.  Let’s look at that code now: 1: using System; 2: using System.Collections.Generic; 3: using System.Configuration; 4: using System.Linq; 5: using System.Text; 6: using System.Threading.Tasks; 7:  8: namespace ConnectionManagerUpdater.Data.Configuration 9: { 10: public class ConnectionManagerDataSection : ConfigurationSection 11: { 12: /// <summary> 13: /// The name of this section in the app.config. 14: /// </summary> 15: public const string SectionName = "ConnectionManagerDataSection"; 16: 17: private const string EndpointCollectionName = "ConnectionManagerEndpoints"; 18:  19: [ConfigurationProperty(EndpointCollectionName)] 20: [ConfigurationCollection(typeof(ConnectionManagerEndpointsCollection), AddItemName = "add")] 21: public ConnectionManagerEndpointsCollection ConnectionManagerEndpoints { get { return (ConnectionManagerEndpointsCollection)base[EndpointCollectionName]; } } 22: } 23:  24: public class ConnectionManagerEndpointsCollection : ConfigurationElementCollection 25: { 26: protected override ConfigurationElement CreateNewElement() 27: { 28: return new ConnectionManagerEndpointElement(); 29: } 30: 31: protected override object GetElementKey(ConfigurationElement element) 32: { 33: return ((ConnectionManagerEndpointElement)element).Name; 34: } 35: } 36: 37: public class ConnectionManagerEndpointElement : ConfigurationElement 38: { 39: [ConfigurationProperty("name", IsRequired = true)] 40: public string Name 41: { 42: get { return (string)this["name"]; } 43: set { this["name"] = value; } 44: } 45: 46: [ConfigurationProperty("address", IsRequired = true)] 47: public string Address 48: { 49: get { return (string)this["address"]; } 50: set { this["address"] = value; } 51: } 52: 53: [ConfigurationProperty("useSSL", IsRequired = false, DefaultValue = false)] 54: public bool UseSSL 55: { 56: get { return (bool)this["useSSL"]; } 57: set { this["useSSL"] = value; } 58: } 59: 60: [ConfigurationProperty("securityGroupsAllowedToSaveChanges", IsRequired = false)] 61: public string SecurityGroupsAllowedToSaveChanges 62: { 63: get { return (string)this["securityGroupsAllowedToSaveChanges"]; } 64: set { this["securityGroupsAllowedToSaveChanges"] = value; } 65: } 66: } 67: }   So here the first class we declare is the one that appears in the <configSections> element of the app.config.  It is ConnectionManagerDataSection and it inherits from the necessary System.Configuration.ConfigurationSection class.  This class just has one property (other than the expected section name), that basically just says I have a Collection property, which is actually a ConnectionManagerEndpointsCollection, which is the next class defined.  The ConnectionManagerEndpointsCollection class inherits from ConfigurationElementCollection and overrides the requied fields.  The first tells it what type of Element to create when adding a new one (in our case a ConnectionManagerEndpointElement), and a function specifying what property on our ConnectionManagerEndpointElement class is the unique key, which I’ve specified to be the Name field. The last class defined is the actual meat of our elements.  It inherits from ConfigurationElement and specifies the properties of the element (which can then be set in the xml of the App.config).  The “ConfigurationProperty” attribute on each of the properties tells what we expect the name of the property to correspond to in each element in the app.config, as well as some additional information such as if that property is required and what it’s default value should be. Finally, the code to actually access these values would look like this: 1: // Grab the Environments listed in the App.config and add them to our list. 2: var connectionManagerDataSection = ConfigurationManager.GetSection(ConnectionManagerDataSection.SectionName) as ConnectionManagerDataSection; 3: if (connectionManagerDataSection != null) 4: { 5: foreach (ConnectionManagerEndpointElement endpointElement in connectionManagerDataSection.ConnectionManagerEndpoints) 6: { 7: var endpoint = new ConnectionManagerEndpoint() { Name = endpointElement.Name, ServerInfo = new ConnectionManagerServerInfo() { Address = endpointElement.Address, UseSSL = endpointElement.UseSSL, SecurityGroupsAllowedToSaveChanges = endpointElement.SecurityGroupsAllowedToSaveChanges.Split(',').Where(e => !string.IsNullOrWhiteSpace(e)).ToList() } }; 8: AddEndpoint(endpoint); 9: } 10: } This looks very similar to what we had before in the “simple” example.  The main points of interest are that we cast the section as ConnectionManagerDataSection (which is the class we defined for our section) and then iterate over the endpoints collection using the ConnectionManagerEndpoints property we created in the ConnectionManagerDataSection class.   Also, some other helpful resources around using app.config that I found (and for parts that I didn’t really explain in this article) are: How do you use sections in C# 4.0 app.config? (Stack Overflow) <== Shows how to use Section Groups as well, which is something that I did not cover here, but might be of interest to you. How to: Create Custom Configuration Sections Using Configuration Section (MSDN) ConfigurationSection Class (MSDN) ConfigurationCollectionAttribute Class (MSDN) ConfigurationElementCollection Class (MSDN)   I hope you find this helpful.  Feel free to leave a comment.  Happy Coding!

• Do we need to explicitly pass php.ini's location to php-fpm?

  - by F21

  I am seeing a strange issue where my php.ini is not used if I do not explicitly pass it to php-fpm when starting it. This is the upstart script I am using: start on (filesystem and net-device-up IFACE=lo) stop on runlevel [016] pre-start script mkdir -p /run/php end script expect fork respawn exec /usr/local/php/sbin/php-fpm --fpm-config /etc/php/php-fpm.conf If PHP is started with the above, my php.ini is never used, even though it is in Configuration File (php.ini) Path. This is the relevant part from phpinfo(): Configuration File (php.ini) Path /etc/php/ Loaded Configuration File (none) Scan this dir for additional .ini files (none) Additional .ini files parsed (none) If I modify the last line of the upstart script to point php-fpm to php.ini explicitly: exec /usr/local/php/sbin/php-fpm --fpm-config /etc/php/php-fpm.conf -c /etc/php/php.ini Then we see that the php.ini is loaded: Configuration File (php.ini) Path /etc/php/ Loaded Configuration File /etc/php/php.ini Scan this dir for additional .ini files (none) Additional .ini files parsed (none) Why is this the case? Is this a quirk in php-fpm? Minor update: This also seems to be a problem for php5-fpm installed using apt-get. I did a test install in a Ubuntu Server 12.04 virtual machine by running the following: sudo apt-get install nginx php5-fpm PHP-FPM and nginx were started after installation and everything seemed fine. I then uncommented php's settings in nginx's configuration and placed a test phpinfo() file to inspect PHP's settings. The relevant bits are: Configuration File (php.ini) Path /etc/php5/fpm Loaded Configuration File (none) Scan this dir for additional .ini files /etc/php5/fpm/conf.d Additional .ini files parsed /etc/php5/fpm/conf.d/10-pdo.ini I noted that no php.ini was loaded either. However, if I go to /etc/php5/fpm, I can see that a php.ini exists. I also checked the start up scripts for PHP-FPM and the -c parameter was not used to link the ini file to PHP. This can potentially be confusing for people who would expect php.ini to be loaded automatically by PHP-FPM.

• Recent improvements in Console Performance

  - by loren.konkus

  Recently, the WebLogic Server development and support organizations have worked with a number of customers to quantify and improve the performance of the Administration Console in large, distributed configurations where there is significant latency in the communications between the administration server and managed servers. These improvements fall into two categories: Constraining the amount of time that the Console stalls waiting for communication Reducing and streamlining the amount of data required for an update A few releases ago, we added support for a configurable domain-wide mbean "Invocation Timeout" value on the Console's configuration: general, advanced section for a domain. The default value for this setting is 0, which means wait indefinitely and was chosen for compatibility with the behavior of previous releases. This configuration setting applies to all mbean communications between the admin server and managed servers, and is the first line of defense against being blocked by a stalled or completely overloaded managed server. Each site should choose an appropriate timeout value for their environment and network latency. In the next release of WebLogic Server, we've added an additional console preference, "Management Operation Timeout", to the Console's shared preference page. This setting further constrains how long certain console pages will wait for slowly responding servers before returning partial results. While not all Console pages support this yet, key pages such as the Servers Configuration and Control table pages and the Deployments Control pages have been updated to support this. For example, if a user requests a Servers Table page and a Management Operation Timeout occurs, the table is displayed with both local configuration and remote runtime information from the responding managed servers and only local configuration information for servers that did not yet respond. This means that a troublesome managed server does not impede your ability to manage your domain using the Console. To support these changes, these Console pages have been re-written to use the Work Management feature of WebLogic Server to interact with each server or deployment concurrently, which further improves the responsiveness of these pages. The basic algorithm for these pages is: For each configuration mbean (ie, Servers) populate rows with configuration attributes from the fast, local mbean server Find a WorkManager For each server, Create a Work instance to obtain runtime mbean attributes for the server Schedule Work instance in the WorkManager Call WorkManager.waitForAll to wait WorkItems to finish, constrained by Management Operation Timeout For each WorkItem, if the runtime information obtained was not complete, add a message indicating which server has incomplete data Display collected data in table In addition to these changes to constrain how long the console waits for communication, a number of other changes have been made to reduce the amount and scope of managed server interactions for key pages. For example, in previous releases the Deployments Control table looked at the status of a deployment on every managed server, even those servers that the deployment was not currently targeted on. (This was done to handle an edge case where a deployment's target configuration was changed while it remained running on previously targeted servers.) We decided supporting that edge case did not warrant the performance impact for all, and instead only look at the status of a deployment on the servers it is targeted to. Comprehensive status continues to be available if a user clicks on the 'status' field for a deployment. Finally, changes have been made to the System Status portlet to reduce its impact on Console page display times. Obtaining health information for this display requires several mbean interactions with managed servers. In previous releases, this mbean interaction occurred with every display, and any delay or impediment in these interactions was reflected in the display time for every page. To reduce this impact, we've made several changes in this portlet: Using Work Management to obtain health concurrently Applying the operation timeout configuration to constrain how long we will wait Caching health information to reduce the cost during rapid navigation from page to page and only obtaining new health information if the previous information is over 30 seconds old. Eliminating heath collection if this portlet is minimized. Together, these Console changes have resulted in significant performance improvements for the customers with large configurations and high latency that we have worked with during their development, and some lesser performance improvements for those with small configurations and very fast networks. These changes will be included in the 11g Rel 1 patch set 2 (10.3.3.0) release of WebLogic Server.

• dynamic? I'll never use that ... or then again, maybe it could ...

  - by adweigert

  So, I don't know about you, but I was highly skeptical of the dynamic keywork when it was announced. I thought to myself, oh great, just another move towards VB compliance. Well after seeing it being used in things like DynamicXml (which I use for this example) I then was working with a MVC controller and wanted to move some things like operation timeout of an action to a configuration file. Thinking big picture, it'd be really nice to have configuration for all my controllers like that. Ugh, I don't want to have to create all those ConfigurationElement objects... So, I started thinking self, use what you know and do something cool ... Well after a bit of zoning out, self came up with use a dynamic object duh! I was thinking of a config like this ...<controllers> <add type="MyApp.Web.Areas.ComputerManagement.Controllers.MyController, MyApp.Web"> <detail timeout="00:00:30" /> </add> </controllers> So, I ended up with a couple configuration classes like this ...blic abstract class DynamicConfigurationElement : ConfigurationElement { protected DynamicConfigurationElement() { this.DynamicObject = new DynamicConfiguration(); } public DynamicConfiguration DynamicObject { get; private set; } protected override bool OnDeserializeUnrecognizedAttribute(string name, string value) { this.DynamicObject.Add(name, value); return true; } protected override bool OnDeserializeUnrecognizedElement(string elementName, XmlReader reader) { this.DynamicObject.Add(elementName, new DynamicXml((XElement)XElement.ReadFrom(reader))); return true; } } public class ControllerConfigurationElement : DynamicConfigurationElement { [ConfigurationProperty("type", Options = ConfigurationPropertyOptions.IsRequired | ConfigurationPropertyOptions.IsKey)] public string TypeName { get { return (string)this["type"]; } } public Type Type { get { return Type.GetType(this.TypeName, true); } } } public class ControllerConfigurationElementCollection : ConfigurationElementCollection { protected override ConfigurationElement CreateNewElement() { return new ControllerConfigurationElement(); } protected override object GetElementKey(ConfigurationElement element) { return ((ControllerConfigurationElement)element).Type; } } And then had to create the meat of the DynamicConfiguration class which looks like this ...public class DynamicConfiguration : DynamicObject { private Dictionary<string, object> properties = new Dictionary<string, object>(StringComparer.CurrentCultureIgnoreCase); internal void Add<T>(string name, T value) { this.properties.Add(name, value); } public override bool TryGetMember(GetMemberBinder binder, out object result) { var propertyName = binder.Name; result = null; if (this.properties.ContainsKey(propertyName)) { result = this.properties[propertyName]; } return true; } } So all being said, I made a base controller class like a good little MVC-itizen ...public abstract class BaseController : Controller { protected BaseController() : base() { var configuration = ManagementConfigurationSection.GetInstance(); var controllerConfiguration = configuration.Controllers.ForType(this.GetType()); if (controllerConfiguration != null) { this.Configuration = controllerConfiguration.DynamicObject; } } public dynamic Configuration { get; private set; } } And used it like this ...public class MyController : BaseController { static readonly string DefaultDetailTimeout = TimeSpan.MaxValue.ToString(); public MyController() { this.DetailTimeout = TimeSpan.Parse(this.Configuration.Detail.Timeout ?? DefaultDetailTimeout); } public TimeSpan DetailTimeout { get; private set; } } And there I have an actual use for the dynamic keyword ... never thoguht I'd see the day when I first heard of it as I don't do much COM work ... oh dont' forget this little helper extension methods to find the controller configuration by the controller type.public static ControllerConfigurationElement ForType<T>(this ControllerConfigurationElementCollection collection) { Contract.Requires(collection != null); return ForType(collection, typeof(T)); } public static ControllerConfigurationElement ForType(this ControllerConfigurationElementCollection collection, Type type) { Contract.Requires(collection != null); Contract.Requires(type != null); return collection.Cast<ControllerConfigurationElement>().Where(element => element.Type == type).SingleOrDefault(); } Sure, it isn't perfect and I'm sure I can tweak it over time, but I thought it was a pretty cool way to take advantage of the dynamic keyword functionality. Just remember, it only validates you did it right at runtime, which isn't that bad ... is it? And yes, I did make it case-insensitive so my code didn't have to look like my XML objects, tweak it to your liking if you dare to use this creation.

  I am doing connection string encryption. we use our own encryption key with AES algorithm to do this. during the process, we need to convert string to byte array and then convert byte array back to string. I found the encoding play an important role on those conversions. So I need to know the encoding C# is using to get above conversion right. Any idea how to get current encoding programmably? thanks,

• How do I refer to a constant URL in my route configuration?

  - by Remnant

  Suppose I have the following within a webpage <% using (Html.BeginForm("ShowData", "Summary")) %> <% { %> <div class="dropdown"><%=Html.DropDownList("CourseSelection", Model.CourseList, new { @class = "dropdown", onchange="this.form.submit();" })%> </div> <% } %> When the user makes a selection from the dropdown the form is submitted and I would like it to link to another page with a URL as follows: http://localhost:1721/Summary I have the following routes: routes.MapRoute(null, "Summary", new { controller = "Summary", action = "ShowData", CourseSelection = (string) null }); routes.MapRoute("Default", "{controller}/{action}/{id}", new { controller = "Login", action = "Index", id = UrlParameter.Optional }); When a user selects an item in the dropdownlist, the URL returned is: http://localhost:1721/Summary/ShowData?CourseSelection = UserSelection Clearly the first route in the list is not being matched. I don't want the URL to show the action name and parameter. I simply want to show "Summary" which is what I have hard coded in the URL. How do I achieve this?

• How many disks is too many in this RAID 5 configuration??

  - by Tom

  HP 2012i SAN, 7 disks in RAID 5 with 1 hot spare, took several days to expand the volume from 5 to 7 300GB SAS drives. Looking for suggestions about when and how I would determine that having 2 volumes in the SAN, each one with RAID 5, would be better?? I can add 3 more drives to the controller someday, the SAN is used for ESX/vSphere VMs. Thank you...
