• point subdomain to (sub-) directory on IIS 7

  - by Max

  I have quite a newbie question, but here it is anyway: one of our customers has a domain, e. g. examplecustomer.com which points to the customers website. This server is a apache webserver. Now we have another server using IIS 7, where some .NET web app will be running. This .NET app is in a subdirectory of the windows webserver, e. g. C:\inetpub\wwwroot\my_app\ What I would like to have: a subdomain like app.examplecustomer.com points to C:\inetpub\wwwroot\my_app\ (no redirect or so, app.examplecustomer.com is the domain that the web app is using). How can I setup the windows webserver to work that way? It should still be possible to host other apps on that server, too. Like: anotherapp.examplecustomer.com goes to C:\inetpub\wwwroot\my_anotherapp\ etc.

• Password format not liked by installer

  - by Box293

  I'm installing Chargeback and I get to the database-related information page (step 5 on page 17 of the users guide). Using a Windows account (it is an administrator of the server and I am logged on as that user) Username: DOMAIN\ServiceVMware-CB Password: #$%UuuU2u (this isn't the password but it does start with #$% and is the same length and case) I click the Test Connected and it returns back OK. I click Next and then I am given a warning telling me that the account does not have the right permissions. Check that it has log on as a service etc etc etc. I quit the installer. I change the password in the domain to Uuuuuu3 I reboot the server I restart the server The installer has no problems with the newer password. I'm not fussed either way, I'm just trying to save someone else the pain and perhaps the allowed password format could be added to the documentation. BTW I am using Server 2008 SP2 x64 with SQL Express 2005 x64.

• Mac OS X Server DNS Questions

  - by kreativefinally

  Just for a new mac server in the office, initially it was for my personal use as a web development box but now the boss wants me to set it up with all the bells and whistles it comes with. I'm having some issues with the following... Lets just say my business is example.com I want the server's actual address to be labs.example.com and accessible to the world. What do I need to set up at my domain registrar to let the domain know where to go, and what do I need to set up with my hosting company to make this work, and finally what do I need to set up in the server admin panel to get it to work. It seems that DNS not working is first hurdle I need to jump but the documentation around the internet is pretty terrible. Thank you community.

• Upgrade Your Existing BI Publisher 11g (11.1.1.3) to 11.1.1.5

  - by Kan Nishida

  It’s already more than a month now since BI Publisher 11.1.1.5 was released at beginning of May. Have you already tried out many of the great new features? If you are already running on the first version of BI Publisher 11g (11.1.1.3) you might wonder how to upgrade the existing BI Publisher to the 11.1.1.5 version. There are two ways to do this, one is ‘Out-Place’ and another is ‘In-Place’. The ‘Out-Place’ would be quite simple. Basically you will need to install the whole BI or just BI Publisher standalone R11.1.1.5 at a different location then you can switch the catalog to the existing one so that all the reports will be there in the new 11.1.1.5 environment. But sometimes things are not that simple, you might have some custom applications or configuration on the original environment and you want to keep all of them with the upgraded environment. For such scenarios, there is the ‘In-Place’ upgrade, which overrides on top of the original environment only the parts relevant for BI and BI Publisher, and that’s what I’m going to talk about today. Here is the basic steps of the ‘In-Place’ upgrade. Upgrade WebLogic Server to 10.3.5 Upgrade BI System to 11.1.1.5 Upgrade Database Schema Re-register BI Components Upgrade FMW (Fusion Middleware) Configuration Upgrade BI Catalog There is a section that talks about this upgrade from 11.1.1.3 to 11.1.1.5 as part of the overall upgrade document. But I hope my blog post summarized it and made it simple for you to cover only what’s necessary. Upgrade Document: http://download.oracle.com/docs/cd/E21764_01/bi.1111/e16452/bi_plan.htm#BABECJJH Before You Start Stop BI System and Backup I can’t emphasize enough, but before you start PLEASE make sure you take a backup of the existing environments first. You want to stop all WebLogic Servers, Node Manager, OPMN, and OPMN-managed system components that are part of your Oracle BI domains. If you’re on Windows you can do this by simply selecting ‘Stop BI Services’ menu. Then backup the whole system. Upgrade WebLogic Server to 10.3.5 Download WebLogic Server 10.3.5 Upgrade Installer With BI 11.1.1.3 installation your WebLogic Server (WLS) is 10.3.3 and you need to upgrade this to 10.3.5 before upgrading the BI part. In order to upgrade you will need this 10.3.5 upgrade version of WLS, which you can download from our support web site (https://support.oracle.com) You can find the detail information about the installation and the patch numbers for the WLS upgrade installer on this document. Just for your short cut, if you are running on Windows or Linux (x86) here is the patch number for your platform. Windows 32 bit: 12395517: Linux: 12395517 Upgrade WebLogic Server 1. After unzip the downloaded file, launch wls1035_upgrade_win32.exe if you’re on Windows. 2. Accept all the default values and keep ‘Next’ till end, and start the upgrade. Once the upgrade process completes you’ll see the following window. Now let’s move to the BI upgrade. Upgrade BI Platform to 11.1.1.5 with Software Only Install Download BI 11.1.1.5 You can download the 11.1.1.5 version from our OTN page for your evaluation or development. For the production use it’s recommended to download from eDelivery. 1. Launch the installer by double click ‘setup.exe’ (for Windows) 2. Select ‘Software Only Install’ option 3. Select your original Oracle Home where you installed BI 11.1.1.3. 4. Click ‘Install’ button to start the installation. And now the software part of the BI has been upgraded to 11.1.1.5. Now let’s move to the database schema upgrade. Upgrade Database Schema with Patch Assistant You need to upgrade the BIPLATFORM and MDS Schemas. You can use the Patch Assistant utility to do this, and here is an example assuming you’ve created the schema with ‘DEV’ prefix, otherwise change it with yours accordingly. Upgrade BIPLATFORM schema (if you created this schema with DEV_ prev) psa.bat -dbConnectString localhost:1521:orcl -dbaUserName sys -schemaUserName DEV_BIPLATFORM Upgrade MDS schema (if you created this schema with DEV_ prev) psa.bat -dbConnectString localhost:1521:orcl -dbaUserName sys -schemaUserName DEV_MDS Re-register BI System components Now you need to re-register your BI system components such as BI Server, BI Presentation Server, etc to the Fusion Middleware system. You can do this by running ‘upgradenonj2eeapp.bat (or .sh)’ command, which can be found at %ORACLE_HOME%/opmn/bin. Before you run, you need to start the WLS Server and make sure your WLS environment is not locked. If it’s locked then you need to release the system from the Fusion Middleware console before you run the following command. Here is the syntax for the ‘upgradenonj2eeapp.bat (or .sh) command.  upgradenonj2eeapp.bat    -oracleInstance Instance_Home_Location    -adminHost WebLogic_Server_Host_Name    -adminPort administration_server_port_number    -adminUsername administration_server_user And here is an example: cd %BI_HOME%\opmn\bin upgradenonj2eeapp.bat -oracleInstance C:\biee11\instances\instance1 -adminHost localhost -adminPort 7001 -adminUsername weblogic Upgrade Fusion Middleware Configuration There are a couple things on the Fusion Middleware need to be upgraded for the BI system to work. Here is a list of the components to upgrade. Upgrade Shared Library (JRF) Upgrade Fusion Middleware Security (OPSS) Upgrade Code Grants Upgrade OWSM Policy Repository Before moving forward, you need to stop the WebLogic Server. Here is an example. cd %MW_HOME%user_projects\domains\bifoundation_domain\binstopWebLogic.cmd And, let’s start with ‘Upgrade Shared Library (JRF)’. Upgrade Shared Library (JRF) You can use updateJRF() WLST command to upgrade the shared libraries in your domain. Before you do this, you need to stop all running instances, Managed Servers, Administration Server, and Node Manager in the domain. Here is an example of the ‘upgradeJRF()’ command: cd %MW_HOME%\oracle_common\common\bin wlst.cmd upgradeJRF('C:/biee11/user_projects/domains/bifoundation_domain') Upgrade Fusion Middleware Security (OPSS) This step is to upgrade the Fusion Middleware security piece. You can use ‘upgradeOpss()’ WLST command. Here is a syntax for the command. upgradeOpss(jpsConfig="existing_jps_config_file", jaznData="system_jazn_data_file") The ‘existing jps-config.xml file can be found under %DOMAIN_HOME%/config/fmwconfig/jps-config.xml and the ‘system_jazn_data_file’ can be found under %MW_HOME%/oracle_common/modules/oracle.jps_11.1.1/domain_config/system-jazn-data.xml. And here is an example: cd %MW_HOME%\oracle_common\common\bin wlst.cmd upgradeOpss(jpsConfig="c:/biee11/user_projects/domains/bifoundation_domain/config/fmwconfig/jps-config.xml", jaznData="c:/biee11/oracle_common/modules/oracle.jps_11.1.1/domain_config/system-jazn-data.xml") exit() Upgrade Code Grants for Oracle BI Domain And this is the last step for the Fusion Middleware platform upgrade task. You need to run this python script ‘bi-upgrade.py‘ script to configure the code grants necessary to ensure that SSL works correctly for Oracle BI. However, even if you don’t use SSL, you still need to run this script. And if you have multiple BI domains (Enterprise deployment) then you need to run this on each domain. Here is an example: cd %MW_HOME%\oracle_common\common\bin wlst c:\biee11\Oracle_BI1\bin\bi-upgrade.py --bioraclehome c:\biee11\Oracle_BI1 --domainhome c:\biee11\user_projects\domains\bifoundation_domain Upgrade OWSM Policy Repository This is to upgrade OWSM (Oracle Web Service Manager) policy repository, you can use WLST command ‘upgradeWSMPolicyRepository()’. In order to run this command you need to have your WebLogic Server up-and-running. Here is an example. cd %MW_HOME%user_projects\domains\bifoundation_domain\binstopWebLogic.cmd cd %MW_HOME%\oracle_common\common\bin wlst.cmd connect ('weblogic','welcome1','t3://localhost:7001') upgradeWSMPolicyRepository() exit() Upgrade BI Catalogs This step is required only when you have your BI Publisher integrated with BIEE. If your BI Publisher is deployed as a standalone then you don’t need to follow this step. Now finally, you can upgrade the BI catalog. This won’t upgrade your BI Publisher reports themselves, but it just upgrades some attributes information inside the catalog. Before you do this upgrade, make sure the BI system components are not running. You can check the status by the command below. opmnctl status You can do the upgrade by updating a configuration file ‘instanceconfig.xml’, which can be found at %BI_HOME%\instances\instance1\config\coreapplication_obips1, and change the value of ‘UpgradeAndExit’ to be ‘true’. Here is an example: <ps:Catalog xmlns:ps="oracle.bi.presentation.services/config/v1.1"> <ps:UpgradeAndExit>true</ps:UpgradeAndExit> </ps:Catalog> After you made the change and save the file, you need to start the BI Presentation Server. This time you want to start only the BI Presentation Server instead of starting all the servers. You can use ‘opmnctl’ to do so, and here is an example. cd %ORACLE_INSTANCE%\bin opmnctl startproc ias-component=coreapplication_obips1 This would upgrade your BI Catalog to be 11.1.1.5. After the catalog is updated, you can stop the BI Presentation Server so that you can modify the instanceconfig.xml file again to revert the upgradeAndExit value back to ‘false’. Start Explore BI Publisher 11.1.1.5 After all the above steps, you can start all the BI Services, access to the same URL, now you have your BI Publisher and/or BI 11.1.1.5 in your hands. Have fun exploring all the new features of R11.1.1.5!

• Beware: Upgrade to ASP.NET MVC 2.0 with care if you use AntiForgeryToken

  - by James Crowley

  If you're thinking of upgrading to MVC 2.0, and you take advantage of the AntiForgeryToken support then be careful - you can easily kick out all active visitors after the upgrade until they restart their browser. Why's this?For the anti forgery validation to take place, ASP.NET MVC uses a session cookie called "__RequestVerificationToken_Lw__". This gets checked for and de-serialized on any page where there is an AntiForgeryToken() call. However, the format of this validation cookie has apparently changed between MVC 1.0 and MVC 2.0. What this means is that when you make to switch on your production server to MVC 2.0, suddenly all your visitors session cookies are invalid, resulting in calls to AntiForgeryToken() throwing exceptions (even on a standard GET request) when de-serializing it: [InvalidCastException: Unable to cast object of type 'System.Web.UI.Triplet' to type 'System.Object[]'.]   System.Web.Mvc.AntiForgeryDataSerializer.Deserialize(String serializedToken) +104[HttpAntiForgeryException (0x80004005): A required anti-forgery token was not supplied or was invalid.]   System.Web.Mvc.AntiForgeryDataSerializer.Deserialize(String serializedToken) +368   System.Web.Mvc.HtmlHelper.GetAntiForgeryTokenAndSetCookie(String salt, String domain, String path) +209   System.Web.Mvc.HtmlHelper.AntiForgeryToken(String salt, String domain, String path) +16   System.Web.Mvc.HtmlHelper.AntiForgeryToken() +10  <snip> So you've just kicked all your active users out of your site with exceptions until they think to restart their browser (to clear the session cookies). The only work around for now is to either write some code that wipes this cookie - or disable use of AntiForgeryToken() in your MVC 2.0 site until you're confident all session cookies will have expired. That in itself isn't very straightforward, given how frequently people tend to hibernate/standby their machines - the session cookie will only clear once the browser has been shut down and re-opened. Hope this helps someone out there!

• OBIEE 11.1.1 - Disable Wrap Data Types in WebLogic Server 10.3.x

  - by Ahmed Awan

  By default, JDBC data type’s objects are wrapped with a WebLogic wrapper. This allows for features like debugging output and track connection usage to be done by the server. The wrapping can be turned off by setting this value to false. This improves performance, in some cases significantly, and allows for the application to use the native driver objects directly. Tip: How to Disable Wrapping in WLS Administration Console You can use the Administration Console to disable data type wrapping for following JDBC data sources in bifoundation_domain domain: Data Source Name bip_datasource mds-owsm EPMSystemRegistry   To disable wrapping for each JDBC data source (as stated in above table): 1.     If you have not already done so, in the Change Center of the Administration Console, click Lock & Edit. 2.     In the Domain Structure tree, expand Services, then select Data Sources. 3.     On the Summary of Data Sources page, click the data source name for example “mds-owsm”. 4.     Select the Configuration: Connection Pool tab. 5.     Scroll down and click Advanced to show the advanced connection pool options. 6.     In Wrap Data Types, deselect the checkbox to disable wrapping. 7.     Click Save. 8.     To activate these changes, in the Change Center of the Administration Console, click Activate Changes. Important Note: This change does not take effect immediately—it requires the server be restarted.

• ASP.NET MVC Framework

  - by Aamir Hasan

   MVC is a design pattern. A reusable "recipe" for constructing your application. Generally, you don't want your user interface code and data access code to be mixed together, it makes changing either one more difficult. By placing data access code into a "Model" object and user interface code into a "View" object, you can use a "Controller" object to act as a go-between, sending messages/calling methods on the view object when the data changes and vice versa. Model-view-controller (MVC) is an architectural pattern used in software engineering. In complex computer applications that present a large amount of data to the user, a developer often wishes to separate data (model) and user interface (view) concerns, so that changes to the user interface will not affect data handling, and that the data can be reorganized without changing the user interface. The model-view-controller solves this problem by decoupling data access and business logic from data presentation and user interaction, by introducing an intermediate component: the controller.Model:    The domain-specific representation of the information that the application operates. Domain logic adds meaning to raw data (e.g., calculating whether today is the user's birthday, or the totals, taxes, and shipping charges for shopping cart items).    Many applications use a persistent storage mechanism (such as a database) to store data. MVC does not specifically mention the data access layer because it is understood to be underneath or encapsulated by the Model.View:    Renders the model into a form suitable for interaction, typically a user interface element. Multiple views can exist for a single model for different purposes.Controller:    Processes and responds to events, typically user actions, and may invoke changes on the model.

Let us see a small tutorial how to create conditions and policy which will prevent any future SP to be created with any other prefix. 2009 Performance Counters from System Views – By Kevin Mckenna Many of you are not aware of this fact that access to performance information is readily available in SQL Server and that too without querying performance counters using a custom application or via perfmon. Till now, this fact has remained undisclosed but through this post I would like to explain you can easily access SQL Server performance counter information. Without putting much effort you will come across the system viewsys.dm_os_performance_counters. As the name suggests, this provides you easy access to the SQL Server performance counter information that is passed on to perfmon, but you can get at it via tsql. Customize Toolbar – Remove Debug Button from Toolbar I was fond of SQL Server Debugger feature in SQL Server 2000. To my utter disappointment, this feature was withdrawn from SQL Server 2005. The button of the debugger is similar to a play button and is used to run debugging commands of Visual Studio. Because of this reason, it gets very much infuriating for developers when they are developing on both – Visual Studio and SSMS. Let us now see how we can remove debugging button from SQL Server Management Studio. Effect of Normalization on Index and Performance A very interesting conversation which started from twitter. If you want to read one link this is the link I encourage you to read it. SSMS Feature – Multi-server Queries Using SQL Server Management Studio (SSMS) DBAs can now query multiple servers from one window. It is quite common for DBAs with large amount of servers to maintain and gather information from multiple SQL Servers and create report. This feature is a blessing for the DBAs, as they can now assemble all the information instantaneously without going anywhere. Query Optimizer Hint ROBUST PLAN – Question to You “ROBUST PLAN” is a kind of query hint which works quite differently than other hints. It does not improve join or force any indexes to use; it just makes sure that a query does not crash due to over the limit size of row. Let me elaborate upon it in the blog post. 2010 Do you really know the difference between various date functions available in SQL Server 2012? Here is a three part story where we explored the same with examples: Fastest Way to Restore the Database Difference Between DATETIME and DATETIME2 Difference Between DATETIME and DATETIME2 – WITH GETDATE Shrinking NDF and MDF Files – Readers’ Opinion Shrinking Database always creates performance degradation and increases fragmentation in the database. I suggest that you keep that in mind before you start reading the following comment. If you are going to say Shrinking Database is bad and evil, here I am saying it first and loud. Now, the comment of Imran is written while keeping in mind only the process showing how the Shrinking Database Operation works. Imran has already explained his understanding and requests further explanation. I have removed the Best Practices section from Imran’s comments, as there are a few corrections. 2011 Solution – Puzzle – SELECT * vs SELECT COUNT(*) This is very interesting question and I am very confident that not every one knows the answer to this question. Let me ask you again – Which will be faster SELECT* or SELECT COUNT (*) or do you think this is apples and oranges comparison. 2012 Service Broker and CAP_CPU_PERCENT – Limiting SQL Server Instances to CPU Usage In SQL Server 2012 there are a few enhancements with regards to SQL Server Resource Governor. One of the enhancement is how the resources are allocated. Let me explain you with examples. Let us understand the entire discussion with the help of three different examples. Finding Size of a Columnstore Index Using DMVs One of the very common question I often see is need of the list of columnstore index along with their size and corresponding table name. I quickly re-wrote a script using DMVs sys.indexes and sys.dm_db_partition_stats. This script gives the size of the columnstore index on disk only. I am sure there will be advanced script to retrieve details related to components associated with the columnstore index. However, I believe following script is sufficient to start getting an idea of columnstore index size. Developer Training Resources and Summary Roundup Developer Training - Importance and Significance - Part 1 In this part we discussed the importance of training in the real world. The most important and valuable resource any company is its employee. Employees who have been well-trained will be better at their jobs and produce a better product.  An employee who is well trained obviously knows more about their job and all the technical aspects. I have a very high opinion about training employees and it is the most important task. Developer Training – Employee Morals and Ethics – Part 2 In this part we discussed the most crucial components of training. Often employees are expecting the company to pay for their training and the company expresses no interest in training the employee. Quite often training expenses are the real issue for both the employee and employer. Developer Training – Difficult Questions and Alternative Perspective - Part 3 This part was the most difficult to write as I tried to address a few difficult questions and answers. Training is such a sensitive issue that many developers when not receiving chance for training think about leaving the organization. Developer Training – Various Options for Developer Training – Part 4 In this part I tried to explore a few methods and options for training. The generic feedback I received on this blog post was short and I should have explored each of the subject of the training in details. I believe there are two big buckets of training 1) Instructor Lead Training and 2) Self Lead Training. Developer Training – A Conclusive Summary- Part 5 There is no better motivation than a personal desire to learn new technology. Honestly there is nothing more personal learning. That “change is the only constant” and “adapt & overcome” are the essential lessons of life. One cannot stop the learning and resist the change. In the IT industry “ego of knowing all” and the “resistance to change” are the most challenging issues. A Quick Look at Logging and Ideas around Logging Question: What is the first thing comes to your mind when you hear the word “Logging”? Strange enough I got a different answer every single time. Let me just list what answer I got from my friends. Let us go over them one by one. Beginning Performance Tuning with SQL Server Execution Plan Solution of Puzzle – Swap Value of Column Without Case Statement Earlier this week I asked a question where I asked how to Swap Values of the column without using CASE Statement. Read here: SQL SERVER – A Puzzle – Swap Value of Column Without Case Statement. I have proposed 3 different solutions in the blog posts itself. I had requested the help of the community to come up with alternate solutions and honestly I am stunned and amazed by the qualified entries.

• Begin the Clone Wars Have!

  - by Antony Reynolds

  Creating a New Virtual Machine from an Existing Virtual Disk In previous posts I described how I set up an OEL6 machine under VirtualBox that can run an 11gR2 database and FMW 11.1.1.5.  That is great if you want the DB and FMW running in the same virtual image and it has served me well for some proof of concepts and also for some testing of different JVMs.  However I also wanted to run some testing of FMW with the database running on a separate physical machine.  So in this post I will show how to take a VirtualBox image and create a new image based on the disks from that original image. What are my Options? There is more than one way to skin a cat, or in this case to create two separate VMs that can run on different hardware.  Some of the options include: Create new virtual disk images for each new VM. Clone the existing disk images and point the new VM at the cloned images. Point the new VM at the existing snapshots. #1 is too much like hard work, install OEL twice, install a database again, install FMW again, run RCU again!  Life is too short! #2 is probably the safest way of doing things.  VirtualBox allows you to clone a disk image for use in a separate machine.  However this of course duplicates the disk and means that it is now occupying 3 times the space, once for the original disk and twice more for the two clones I would need. #3 is the most space efficient way of doing things.  It does mean however that I can only run the new “cloned” images if I have access to the original image because that is where the base snapshots reside.  However this is not a problem for me as long as I remember to keep all threee images together.  So this is the approach we will follow. Snapshot, What Snapshot? As we are going to create new virtual machines based on existing snapshots we need to figure out which snapshot to use.  We do this by opening the “Media Manager” from within VirtualBox and moving the mouse over the snapshot images until we find the snapshots we want – the snapshot name is identified in the “Attached to:” comment.  In my case I wanted the FMW installed snapshot because that had a database configured for FMW alongside the FMW software.  I made a note of the filename of that snapshot (actually I just noted the first 5 characters as that was all that was needed to uniquely identify the snapshot file). When we create the new machines we will point them at the snapshot filename we have just checked. Network or NotWork? Because we want the two new machines to communicate with each other when hosted in different physical machines we can’t use the default NAT networking mode without a lot of hassle.  But at the same time we need them to have fixed IP addresses relative to each other so that they can see each other whilst also being able to see the outside world. To achieve all these requirements I created two network adapters for each machine.  Adapter 1 was a standard NAT mapping.  This will allow each machine to get a dynamic IP address (10.0.2.15 by default) that can be used to access the external world through the VBox provided NAT gateway.  This is the same as the existing configuration. The second adapter I created as a bridged adapter.  This gives the virtual machine direct access to the host network card and by using fixed IP addresses each machine can see the other.  It is important to choose fixed IP addresses that are not routable across your internal network so you don’t get any clashes with other machines on your network.  Of course you could always get proper fixed IP addresses from your network people, but I have serveral people using my images and as long as I don’t have two instances of the same VM on the same network segment this is easier and avoids reconfiguring the network every time someone wants a copy of my VM.  If it is available I would suggest using the 10.0.3.* network as 10.0.2.* is the default NAT network.  You can check availability by pinging 10.0.3.1 and 10.0.3.2 from your host machine.  If it times out then you are probably safe to use that. Creating the New VMs Now that I had collected the data that I needed I went ahead and created the new VMs. When asked for a “Boot Hard Disk” I used the “Choose a virtual hard disk file…” link to find the snapshot I had previously selected and set that to be the existing hard disk.  I chose the previously existing SOA 11.1.1.5 install for both the new DB and FMW machines because that snapshot had the database with the RCU completed that I wanted for my DB machine and it had the SOA software installed which I wanted for my FMW machine. After the initial creation of the virtual machine go into the network setting section and enable a second adapter which will be bridged.  Make a note of the MAC addresses (the last four digits should be sufficient) of the two adapters so that you can later set the bridged adapter to use fixed IP and the NAT adapter to use DHCP. We are now ready to start the VMs and reconfigure Linux. Reconfiguring Linux Because I now have two new machines I need to change their network configuration.  In particular I need to change the hostname, update the hosts file and change the network settings. Changing the Hostname I renamed both hosts by running the hostname command as root: hostname vboxfmw.oracle.com I also edited the /etc/sysconfig file and set the correct hostname in there. HOSTNAME=vboxfmw.oracle.com Changing the Network Settings I needed to change the network configuration to give the bridged network a fixed IP address.  I first explicitly set the MAC addresses of the two adapters, because the order of the virtual adapters in the VirtualBox Manager is not necessarily the same as the order of the adapters in the guest OS.  So I went in to the System->Preferences->Network Connections screen and explicitly set the “Device MAC address” for the two adapters. Having correctly mapped the Linux adapters to the VirtualBox adapters I then set the Bridged adapter to use fixed IP addressing rather than DHCP.  There is no need for additional routing or default gateways because we expect the two machine to be on the same LAN segment. Updating the Hosts File Having renamed the machines and reconfigured the network I then updated the /etc/hosts file to refer to the new machine name add a new line to the hosts file to provide an additional IP address for my server (the new fixed IP address) add a new line for the fixed IP address of the other virtual machine 10.0.3.101      vboxdb.oracle.com       vboxdb  # Added by NetworkManager 10.0.2.15       vboxdb.oracle.com       vboxdb  # Added by NetworkManager 10.0.3.102      vboxfmw.oracle.com      vboxfmw # Added by NetworkManager 127.0.0.1       localhost.localdomain   localhost ::1     vboxdb.oracle.com       vboxdb  localhost6.localdomain6 localhost6 To make sure everything takes effect I restarted the server. Reconfiguring the Database on the DB Machine Because we changed the hostname the listener and the EM console no longer start so I need to modify the listener.ora to use the new hostname and I also need to rebuild the EM configuration because it also relies on the hostname. I edited the $ORACLE_HOME/network/admin/listener.ora and changed the listening address to the new hostname:       (ADDRESS = (PROTOCOL = TCP)(HOST = vboxdb.oracle.com)(PORT = 1521)) After changing the listener.ora I was able to start the listener using: lsnrctl start I also had to reconfigure the EM database control.  I first deconfigured it using the command: emca -deconfig dbcontrol db -repos drop This drops the repository and removes any existing registered dbcontrols. I then re-configured it using the following command: emca -config dbcontrol db -repos create This creates the EM repository and then configures and starts dbcontrol. Now my database machine is ready so I can close it down and take a snapshot. Disabling the Database on the FMW Machine I set up the database to start automatically by creating a service called “dbora”.  On the FMW machine I do not need the database running so I can prevent it auto-starting by running the following command: chkconfig –del dbora Note that because I am using a snapshot it is not a waste of disk space to have the DB installed but not used.  As long as I don’t run it, it won’t cost me anything. I can now close the FMW machine down and take a snapshot. Creating a New Domain The FMW machine is now ready to create a new domain.  When creating the domain I can point it at the second machine which is running the database.  I can potentially run these machines on two separate physical machines as long as I have the original virtual machine available to both of the physical machines. Gotchas in Snapshotting VirtualBox does not support the concept of linked machines in a network like some virtualization technologies so when creating a snapshot it is a good idea to shut both VMs down and then take a snapshot on both of them.  This is because we want to keep the database in sync with the middleware.  One way to make sure that this happens would be to place all the domain configuration files on the database server via an NFS share, this would mean that all we would need to snapshot would be the database machine because that would hold all the state and configuration. The Sky’s the Limit We have covered a simple case of having just two machines.  I have a more complicated configuration in which two machine run a RAC database off the same base OS image, and two more machines run a SOA cluster based on the same OS image.  Just remember what machine holds state and what are the consequences of taking a snapshot.

• Blogger.com kills FTP

  - by Daniel Moth

  History (you can safely ignore) Back in 2002 I came across some (almost) free Linux/Apache space and set up my first manually-created HTML-based home page, which still exists: http://www.danielmoth.com/. In 2004 I wanted to have a blog that would be hosted on a sub-folder of my domain, and at the same time I did not want to mess with setting up a blog engine myself. I found the perfect solution in blogger.com, which offered a web interface for creating blog posts (and managing the pages' template) and it would then use FTP to upload HTML pages to my space (no server-side programming/installation required at all)! FTP feature dropped by blogger.com Unfortunately, along the way Google purchased blogger.com and a couple of months ago they announced that they decided to kill the FTP feature, and they are forcing customers using that feature to have their content hosted (in an opaque way) on Google's servers. Even though I prefer having my content on my own space, I would have considered moving it to Google's servers if I could host my blog in a sub-folder and preserve my full blog URL: http://www.danielmoth.com/Blog/ (including my home pages being hosted at the root of the domain). Sadly, that is not possible. What now So I decided to move my blog somewhere else. I'll document on the next few posts how I did that (inc. a tool I wrote) in case it helps someone else in the same situation and also as a reminder to me if I need to do something like this again in the future. Comments about this post welcome at the original blog.

• Does OSB has any database dependency?

  - by Manoj Neelapu

  Major functionality of OSB is database independent. Most of the internal data-structures that re required by OSB are stored in-memory.Reporting functionality of OSB requires DB tables be accessible.http://download.oracle.com/docs/cd/E14571_01/doc.1111/e15017/before.htm#BABCJHDJ It should hover be noted that we can still run OSB with out creating any tables on database.In such cases the reporting functionality cannot be used where as other functions in OSB will work just as fine.We also see few errors in the log file indicating the absence of these tables which we can ignore.  If reporting function is required we will have to install few tables. http://download.oracle.com/docs/cd/E14571_01/doc.1111/e15017/before.htm#BABBBEHD indicates running RCU recommended. OSB reporting tables are bundled along with SOA schema in RCU. OSB requires two simple tables for reporting functionality and installing complete SOA schema is little far fetched. SOA schema contains lot of tables which OSB doesn't require at all. More over OSB tables are too simple to require a tool like an RCU.Solution to it would be to manually create those tables required for OSB. To make  life easier the definition of tables is available in dbscripts folder under OSB_HOME.eg. D:\Oracle\Middleware\osb\11gPS2\Oracle_OSB1\dbscripts. $OSB_HOME=D:\Oracle\Middleware\osb\11gPS2\Oracle_OSB1If you are not planning to use reporting feature in OSB, then we can also delete the JDBC data sources that comes along with standard OSB domain.WLST script to delete cgDataSources from OSB domain . OSB will work fine with out DB tables and JDBC Datasource.

• ODEE Green Field (Windows) Part 5 - Deployment and Validation

  - by AndyL-Oracle

  And here we are, almost finished with our installation of Oracle Documaker Enterprise Edition ("ODEE") in a Windows green field environment. Let's recap what we've done so far: In part 1, I went over the basic process that I intended to show with installing an ODEE on a green field server. I walked you through the basic installation of Oracle 11g database In part 2, I covered the installation of WebLogic application server. In part 3, I showed you how to install SOA Suite for WebLogic. In part 4, we did the first part of the installation of ODEE itself. What remains after all of that, is the deployment of the ODEE components onto the database and application server - so let's get to it! DATABASE First, we'll deploy the schemas to the database. The schemas are created during the ODEE installation according to the responses provided during the install process. To deploy the schemas, you'll need to login to the database server in your green field environment. Open a command line and CD into ODEE_HOME\documaker\database\oracle11g.Run SQLPLUS as SYSDBA and execute dmkr_admin.sql:  sqlplus / as sysdba @dmkr_admin.sql Execute dmkr_asline.sql, dmkr_admin_correspondence_example.sql.  If you require additional languages, run the appropriate SQL scripts (e.g. dmkr_asline_es.sql for Spanish). APPLICATION SERVER Next, we'll deploy the WebLogic domain and it's components - Documaker web services, Documaker Interactive, Documaker dashboard, and more. To deploy the components, you'll need to login to the application server in your green field environment. 1. Open Windows Explorer and navigate to ODEE_HOME\documaker\j2ee\weblogic\oracle11g\scripts.2. Using a text editor such as Notepad++, modify weblogic_installation_properties and set location of MIDDLEWARE_HOME and ODEE HOME. If you have used the defaults you’ll probably need to change the E: to C: and that’s it. Save the changes.3. Continuing in the same directory, use your text editor to modify set_middleware_env.cmd and set the drive and path to MIDDLEWARE_HOME. If you have used the defaults you’ll probably need to just change E: to C: and that’s it. Save the changes.4. In the same directory, execute wls_create_domain.cmd by double-clicking it. This should run to completion. If it does not, review any errors and correct them, and rerun the script.5. In the same directory, execute wls_add_correspondence.cmd by double-clicking it - again this should run to completion. 6. Next, we'll start the AdminServer - this is the main WebLogic domain server. To start it, use Windows Explorer and navigate to MIDDLEWARE_HOME\user_projects\domains\idocumaker_domain. Double-click startWebLogic.cmd and the server startup will begin. Once you see output that indicates that the server status changed to RUNNING you may proceed.  a. Note: if you saw database connection errors, you probably didn’t make sure your database name and connection type match. You can change this manually in the WebLogic Console. Open a browser and navigate to http://localhost:7001/console (replace localhost with the name of your application server host if you aren't opening the browser on the server), and login with the the weblogic credential you provided in the ODEE installation process. b. Once you're logged in, open Services?Data Sources. Select dmkr_admin and click Connection Pool.  c. The end of the URL should match the connection type you chose. If you chose ServiceName, the URL should be: jdbc:oracle:thin:@//<hostname>:1521/<serviceName> and if you chose SID, the URL should be: jdbc:oracle:thin:@//<hostname>:1521/<SIDname> d. An example serviceName is a fully qualified DNS-style name, e.g. "idmaker.us.oracle.com". (It does not need to actually resolve in DNS). An example SID is just a name, e.g. IDMAKER. e. Save the change and repeat for the data source dmkr_asline.  f. You will also need to make the same changes in the ODEE_HOME/documaker/docfactory/config/context/.bindings file - open the file in a text editor, locate the URL lines and make the appropriate change, then save the file.  7. Back in the ODEE_HOME\documaker\j2ee\weblogic\oracle11g\scripts directory, execute create_users_groups.cmd. 8. In the same directory, execute create_users_groups_correspondence_example.cmd. 9. Open a browser and navigate to http://localhost:7001/jpsquery. Replace localhost with the name of your application server host if you aren't running the browser on the application server. If you changed the default port for the AdminServer from 7001, use the port you changed it to. You should see output like this: 10. Start the WebLogic managed servers by opening a command prompt and navigating to MIDDLEWARE_HOME/user_projects/domains/idocumaker_domain/bin/. When you start the servers listed below, you will be prompted to enter the WebLogic credentials to start the server. You can prevent this by providing the credential in the startManagedwebLogic.cmd file for the WLS_USER and WLS_PASS values. Note that the credential will be stored in cleartext. To start the server, type in the command shown. a. Start the JMS Server: ./startManagedWebLogic.cmd jms_server b. Start Dashboard/Documaker Administrator: ./startManagedWebLogic.cmd dmkr_server c. Start Documaker Interactive for Correspondence: ./startManagedWebLogic.cmd idm_server SOA Composites  If you're planning on testing out the approval process components of BPEL that can be used with Documaker Interactive, then use the following steps to deploy the SOA composites. If you're not going to use BPEL, you can skip to the next section.1. Stop the servers listed in the previous section (Step 10) in the reverse order that they were started.2. Run the Domain configuration command: navigate to and execute MIDDLEWARE_HOME/wlserver_10.3/common/bin/config.cmd.3. Select Extend and click next. 4. Select the iDocumaker Domain and click Next. 5. Select the Oracle SOA Suite – 11.1.1.0 (this may automatically select other components which is OK). Click Next. 6. View the Configure JDBC resources screen. You should not make any changes. Click Next. 7. Check both connections and click Test Connections. After successful test, click Next. If the tests fail, something is broken. Go back to configure JDBC resources and check your service name/SID. 8. Check all schemas. Set a password (will be the same for all schemas). Enter the database information (service name, host name, port). Click Next. 9. Connections should test successfully. If not, go back and fix any errors. Click Next. 10. Click Next to pass through Optional Configuration. 11. Click Extend. 12. Click Done. 13. Open a terminal window and navigate to/execute: ODEE_HOME/documaker/j2ee/weblogic/oracle11g/bpel/antbuild.cmd14. Start the WebLogic Servers – AdminServer, jms_server, dmkr_server, idm_server. If you forgot how to do this, see the previous section Step 10. Note: if you previously changed the startManagedWebLogic.cmd script for WLS_USER and WLS_PASS you will need to make those changes again. 15. Start the WebLogic server soa_server1: MIDDLEWARE_HOME/user_projects/domains/idocumaker_domain/bin/startManagedWebLogic.cmd soa_server116. Open a browser to http://localhost:7001/console and login. 17. Navigate to Services?Data Sources and select DMKR_ASLINE. 18. Click the Targets tab. Check soa_server1, then click Save. Repeat for the DMKR_ADMIN data source. 19. Open a command prompt and navigate to ODEE_HOME/j2ee/weblogic/oracle11g/scripts, then execute deploy_soa.cmd. That's it! (As if that wasn't enough?) DOCUMAKER Deploy the sample MRL resources by navigating to/executing ODEE_HOME/documaker/mstrres/dmres/deploysamplemrl.bat. You should see approximately 500 resources deployed into the database. Start the Factory Services. Start?Run?services.msc. Locate the service named "ODDF xxxx" and right-click, select Start. Note that each Assembly Line has a separate Factory setup, including its own Factory service and Docupresentment service. The services are named for the assembly line and the machine on which they are installed (because you could have multiple machines servicing a single assembly line, so this allows for easy scripting to control all the services if you choose to do so. Repeat for the Docupresentment service. Note that each Assembly Line has a separate Docupresentment. Using Windows Explorer, navigate to ODEE_HOME/documaker/mstrres/dmres/input and select one of the XML files, and copy it into ODEE_HOME/documaker/hotdirectory. Note: if you chose a different hot directory during installation, copy the file there instead. Momentarily you should see the XML file disappear! Open browser and navigate to http://localhost:10001/DocumakerDashboard (previous versions 12.0-12.2 use http://localhost:10001/dashboard) and verify that job processed successfully. Note that some transactions may fail if you do not have a properly configured email server, and this is ok. You can set up a simple SMTP server (just search the internet for "SMTP developer" and you'll get several to choose from.  So... that's it? Where are we at this point? You now have a completely functional ODEE installation, from soup to nuts as they say. You can further expand your installation by doing some of the following activities: clustering WebLogic services configuring WebLogic for redundancy configuring Oracle 11g for RAC adding additional Factory servers for redundancy/processing capacity setting up a real MRL (instead of the sample resources) testing Documaker Web Services for job submission and more!  I certainly hope you've enjoyed this and find it useful. If you find yourself running into trouble, visit the Oracle Community for Documaker - there is plenty of activity there and you can ask questions. For more concentrated assistance, you can engage an Oracle consultant who is a subject matter expert to assist you. Feel free to email me [andy (dot) little (at) oracle (dot) com] and I can connect you with the appropriate resource to get started. Best of luck! -Andy

• WPF Login Verification Using Active Directory

  - by psheriff

  Back in October of 2009 I created a WPF login screen (Figure 1) that just showed how to create the layout for a login screen. That one sample is probably the most downloaded sample we have. So in this blog post, I thought I would update that screen and also hook it up to show how to authenticate your user against Active Directory. Figure 1: Original WPF Login Screen I have updated not only the code behind for this login screen, but also the look and feel as shown in Figure 2. Figure 2: An Updated WPF Login Screen The UI To create the UI for this login screen you can refer to my October of 2009 blog post to see how to create the borderless window. You can then look at the sample code to see how I created the linear gradient brush for the background. There are just a few differences in this screen compared to the old version. First, I changed the key image and instead of using words for the Cancel and Login buttons, I used some icons. Secondly I added a text box to hold the Domain name that you wish to authenticate against. This text box is automatically filled in if you are connected to a network. In the Window_Loaded event procedure of the winLogin window you can retrieve the user’s domain name from the Environment.UserDomainName property. For example: txtDomain.Text = Environment.UserDomainName The ADHelper Class Instead of coding the call to authenticate the user directly in the login screen I created an ADHelper class. This will make it easier if you want to add additional AD calls in the future. The ADHelper class contains just one method at this time called AuthenticateUser. This method authenticates a user name and password against the specified domain. The login screen will gather the credentials from the user such as their user name and password, and also the domain name to authenticate against. To use this ADHelper class you will need to add a reference to the System.DirectoryServices.dll in .NET. The AuthenticateUser Method In order to authenticate a user against your Active Directory you will need to supply a valid LDAP path string to the constructor of the DirectoryEntry class. The LDAP path string will be in the format LDAP://DomainName. You will also pass in the user name and password to the constructor of the DirectoryEntry class as well. With a DirectoryEntry object populated with this LDAP path string, the user name and password you will now pass this object to the constructor of a DirectorySearcher object. You then perform the FindOne method on the DirectorySearcher object. If the DirectorySearcher object returns a SearchResult then the credentials supplied are valid. If the credentials are not valid on the Active Directory then an exception is thrown. C#public bool AuthenticateUser(string domainName, string userName,  string password){  bool ret = false;   try  {    DirectoryEntry de = new DirectoryEntry("LDAP://" + domainName,                                           userName, password);    DirectorySearcher dsearch = new DirectorySearcher(de);    SearchResult results = null;     results = dsearch.FindOne();     ret = true;  }  catch  {    ret = false;  }   return ret;} Visual Basic Public Function AuthenticateUser(ByVal domainName As String, _ ByVal userName As String, ByVal password As String) As Boolean  Dim ret As Boolean = False   Try    Dim de As New DirectoryEntry("LDAP://" & domainName, _                                 userName, password)    Dim dsearch As New DirectorySearcher(de)    Dim results As SearchResult = Nothing     results = dsearch.FindOne()     ret = True  Catch    ret = False  End Try   Return retEnd Function In the Click event procedure under the Login button you will find the following code that will validate the credentials that the user types into the login window. C#private void btnLogin_Click(object sender, RoutedEventArgs e){  ADHelper ad = new ADHelper();   if(ad.AuthenticateUser(txtDomain.Text,         txtUserName.Text, txtPassword.Password))    DialogResult = true;  else    MessageBox.Show("Unable to Authenticate Using the                      Supplied Credentials");} Visual BasicPrivate Sub btnLogin_Click(ByVal sender As Object, _ ByVal e As RoutedEventArgs)  Dim ad As New ADHelper()   If ad.AuthenticateUser(txtDomain.Text, txtUserName.Text, _                         txtPassword.Password) Then    DialogResult = True  Else    MessageBox.Show("Unable to Authenticate Using the                      Supplied Credentials")  End IfEnd Sub Displaying the Login Screen At some point when your application launches, you will need to display your login screen modally. Below is the code that you would call to display the login form (named winLogin in my sample application). This code is called from the main application form, and thus the owner of the login screen is set to “this”. You then call the ShowDialog method on the login screen to have this form displayed modally. After the user clicks on one of the two buttons you need to check to see what the DialogResult property was set to. The DialogResult property is a nullable type and thus you first need to check to see if the value has been set. C# private void DisplayLoginScreen(){  winLogin win = new winLogin();   win.Owner = this;  win.ShowDialog();  if (win.DialogResult.HasValue && win.DialogResult.Value)    MessageBox.Show("User Logged In");  else    this.Close();} Visual Basic Private Sub DisplayLoginScreen()  Dim win As New winLogin()   win.Owner = Me  win.ShowDialog()  If win.DialogResult.HasValue And win.DialogResult.Value Then    MessageBox.Show("User Logged In")  Else    Me.Close()  End IfEnd Sub Summary Creating a nice looking login screen is fairly simple to do in WPF. Using the Active Directory services from a WPF application should make your desktop programming task easier as you do not need to create your own user authentication system. I hope this article gave you some ideas on how to create a login screen in WPF. NOTE: You can download the complete sample code for this blog entry at my website: http://www.pdsa.com/downloads.

• Need help with DNS. Registrar is NS, Web Site at WinHost, Email at eHost

  - by Leon

  Need help moving a web site for a client, which I will call ClientABC. The web site is ClientABC.com, which is hosted at Rackspace, with their email hosted at eHost. We are transferring the site from Rackspace to WinHost and are keeping the email hosted at eHost. I would like the transfer to happen with little to no down time for the web site and email (email is most important). Current Config: Client owns domain and registrar is Network Solutions Domain name is managed by VendorX at Rackspace Web site is hosted on Rackspace servers Email is hosted at eHost Post-Move Config: Web site is hosted at WinHost Keep Email at eHost Here is my plan for the transfer: Copy the site files to WinHost and test to assure site is fully functional Set up the MX record in the WinHost account to point to eHost servers Change the DNS in Network Solutions from Rackspace to Winhost Questions: Will this work? What am I missing? Should I expect down time or any issues with email? I understand that there will be a period of time that traffic to the site is handled at both Rackspace and Winhost and that email traffic will be routed through both hosts as well. Will this cause issues? How will I know when the change is fully propagated and that Rackspace is out of the equation and WinHost is handling everything (so I can kill the Rackspace account) Thanks in advance!

• Ranking hit after site migration

  - by Ben

  I migrated my site from its old domain over a month ago. I followed Google Webmaster Tools completely, including 301 redirects from every existing URL to the new domain, and then submitting a change of address. Traffic continued as normal, but then a few days after submitting the change of address traffic plummeted to about 20-30% of what it was previously. Most of my traffic comes from organic search, and I can see that for the keywords I had targeted before and performed well with and am now ranking much much lower for. In some cases for low competition keywords I've only lost a few places, for higher competition terms I have really suffered. This has started to pick up a bit (one of my keywords I have risen from 195 to 100 in the last week), but it seems to be a very slow process. How seamless is this process normally? I was under the impression that this would not affect my rankings too severely, but it has now been a month since the move and recovery seems to be very slow, if at all. Is it likely that I've missed something? The only change is that I have moved what was the home page to be more of a sub-page, and now in its place is a magazine-style home page. I understand that links to the old site will now be pointing to the latter which means that rankings for some keywords attributed to the old home page will take a hit, but even on other pages that seem to fit in exactly the same page structure as the previous site I have seen a drop in rankings.

• Master-Details with RadGridView for Silverlight 4, WCF RIA Services RC2 and Entity Framework 4.0

  I have prepared a sample project with the Silverlight 4 version of RadGridView released yesterday. The sample project was created with Visual Studio 2010, WCF RIA Services RC 2 for Visual Studio 2010, and ADO.NET Entity Framework (.NET 4). I have decided to use the SalesOrderHeader and SalesOrderDetails tables from the Adventure Works Database, because they provide the perfect one-to-many relationship: I will not go over the steps for creating the ADO.NET Entity Data Model and the Domain Service Class. In case you are not familiar with them, you should start with Brad Abrams series of blog posts and read this blog after that. To enable the master-details relationship we need to modify two things. First of all we need to include the automatic retrieval of the child entities in the domain service class. We do this by using the Include method: 1: public IQueryable<SalesOrderHeader> GetSalesOrderHeaders()...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• How to speed up file transfer to/from Ubuntu Server 11.10 (wifi)

  - by Alexander

  I've been searching AU & elsewhere for the last day and a half. Haven't found an answer so I joined AU to ask for help. I'm hoping someone can point me in the right direction. Ubuntu Server 11.10 Samba VSFTPD Windows 7 PC 2 MacBook Pro - Snow Leopard/Lion 1 iMac - Lion Wireless LAN using DLink DIR-655 Link Speed: 195 Mbit/s on Mac - 54Mbps on Windows ISP Connection: Cable - 20 down/3 up No Domain Controller. All machines are members of the same workgroup. No matter how I connect I can't get better than about 700K transfer rate up/down. Mac/PC, SMB/ftp, Domain Name/Local IP I've tried different user accounts and using different folders, different volumes on the server. Nothing seems to make a difference. 700K up/down. Period. Any suggestions would be greatly appreciated. Thanks, Alexander EDIT: Using sftp now and uploading seems to peak at 980k. After about 5 minutes into a 650MB file, downloading is at 1072k and climbing about 500b/s every ten seconds. If any of that matters... I was expecting a lot faster than 1Mb tx rate. Am I off base here? EDIT: From all I've read so far, perhaps the speed isn't that bad. I only installed Ubuntu out of boredom this past weekend. The trouble is, I like it. Guess it's time to ditch the wifi and run some Cat 5.

• ASP.NET Connections Spring 2012 Talks and Code

  - by Stephen.Walther

  Thank you everyone who attended my ASP.NET Connections talks last week in Las Vegas. I’ve attached the slides and code for the three talks that I delivered:   Using jQuery to interact with the Server through Ajax – In this talk, I discuss the different ways to communicate information between browser and server using Ajax. I explain the difference between the different types of Ajax calls that you can make with jQuery. I also discuss the differences between the JavaScriptSerializer, the DataContractJsonSerializer, and the JSON.NET serializer.   ASP.NET Validation In-Depth – In this talk, I distinguish between View Model Validation and Domain Model Validation. I demonstrate how you can use the validation attributes (including the new .NET 4.5 validation attributes), the jQuery Validation library, and the HTML5 input validation attributes to perform View Model Validation. I then demonstrate how you can use the IValidatableObject interface with the Entity Framework to perform Domain Model Validation.   Using the MVVM Pattern with JavaScript Views – In this talk, I discuss how you can create single page applications (SPA) by taking advantage of the open-source KnockoutJS library and the ASP.NET Web API.   Be warned that the sample code is contained in Visual Studio 11 Beta projects. If you don’t have this version of Visual Studio, then you will need to open the code samples in Notepad. Also, I apologize for getting the code for these talks posted so slowly. I’ve been down with a nasty case of the flu for the past week and haven’t been able to get to a computer.

• How do you deal with translating theory into practice?

  - by Mr. Shickadance

  Hello all! Being a computer scientist in a research field I am often tasked with working alongside professionals outside of the software domain (think math people, electrical engineer etc), and then translating their theories and ideas into real-world implementations. I often find it difficult when they present a theoretical problem which appears to be somewhat disconnected from reality. I am not saying that the theory is bogus, only that it is difficult to translate into real-world situations. For example, recently I have been working with software defined radios. We are exploring many different areas, but often the math specialists in my group would present a problem which is heavily grounded in theory (signal processing, physics, whatever). I often struggle at times where it is hard to draw direct parallels between the theory and the real-world implementation that I need to develop. Say we are working on an energy detector, the theory person in my group would say "you need to measure the noise variance with no signal present." This leads me to think "how the hell do I isolate noise from a signal in reality?" There are many examples, but I hope you see where I am going. So, my question is how does one deal with implementation of theoretical concepts when the theory seems detached from reality? Or at least when the connections are not so clear. Or perhaps, the person with the 'theory' may be ignorant of real restrictions? Note: I found this to be a hard question to ask - hopefully you are following me. If you have suggestions on how I could improve it, by all means let me know! Thanks for looking! EDIT: To be a bit more clear, I understand in situations like this that I must learn that specific domain myself to an extent (i.e. signal processing), but I am more concerned with when those theoretical concepts do not appear to be as grounded in practice as one would like.

• Universal navigation menu across domains

  - by Jon Harley

  I'd like to start by saying that I've searched for hours and could not find a definitive answer to my question. Across different sites on different second-level domains exists a universal navigation bar with a collection of roughly 30 links. This universal bar is exactly the same for every page on each domain. The bar's HTML, CSS and JavaScript are all stored in a subfolder for each domain and the HTML is embedded upon serving the page and is not being injected on the client side. None of the links use any rel directives and are as vanilla as can be. My question is about Google's duplicate content rule. Would something like this be considered duplicate content? Matt Cutt's blog post about duplicate content mentions boilerplate repetition, but then he mentions lengthy legalese. Since the text in this universal bar is brief and uses common terms, I wonder if this same rule applies. If this is considered duplicate content, what would be a good way to correct the problem? Thank you for your help.

• Promoting Organizational Visibility for SOA and SOA Governance Initiatives – Part I by Manuel Rosa and André Sampaio

  - by JuergenKress

  The costs of technology assets can become significant and the need to centralize, monitor and control the contribution of each technology asset becomes a paramount responsibility for many organizations. Through the implementation of various mechanisms, it is possible to obtain a holistic vision and develop synergies between different assets, empowering their re-utilization and analyzing the impact on the organization caused by IT changes. When the SOA domain is considered, the issue of governance should therefore always come into play. Although SOA governance is mandatory to achieve any measure of SOA success, its value still passes incognito in most organizations, mostly due to the lack of visibility and the detached view of the SOA initiatives. There are a number of problems that jeopardize the visibility of these initiatives: Understanding and measuring the value of SOA governance and its contribution – SOA governance tools are too technical and isolated from other systems. They are inadequate for anyone outside of the domain (Business Analyst, Project Managers, or even some Enterprise Architects), and are especially harsh at the CxO level. Lack of information exchange with the business, other operational areas and project management – It is not only a matter of lack of dialog but also the question of using a common vocabulary (textual or graphic) that is adequate for all the stakeholders. We need to generate information that can be useful for a wider scope of stakeholders like Business and enterprise architectures. In this article we describe how an organization can leverage from the existing best practices, and with the help of adequate exploration and communication tools, achieve and maintain the level of quality and visibility that is required for SOA and SOA governance initiatives. Introduction Understanding and implementing effective SOA governance has become a corporate imperative in order to ensure coherence and the attainment of the basic objectives of SOA initiatives: develop the correct services control costs and risks bound to the development process reduce time-to-market Read the full article here.
