• Looking into ASP.Net MVC 4.0 Mobile Development - part 1

  - by nikolaosk

  In this post I will be looking how ASP.Net MVC 4.0 helps us to create web solutions that target mobile devices.We all experience the magic that is the World Wide Web through mobile devices. Millions of people around the world, use tablets and smartphones to view the contents of websites,e-shops and portals.ASP.Net MVC 4.0 includes a new mobile project template and the ability to render a different set of views for different types of devices.There is a new feature that is called browser overriding which allows us to control exactly what a user is going to see from your web application regardless of what type of device he is using.In order to follow along this post you must have Visual Studio 2012 and .Net Framework 4.5 installed in your machine.Download and install VS 2012 using this link.My machine runs on Windows 8 and Visual Studio 2012 works just fine.It will work fine in Windows 7 as well so do not worry if you do not have the latest Microsoft operating system.1) Launch VS 2012 and create a new Web Forms application by going to File - >New Project - > ASP.Net MVC 4 Web Application and then click OKHave a look at the picture below  2) From the available templates select Mobile Application and then click OK.Have a look at the picture below 3) When I run the application I get the mobile view of the page. I would like to show you what a typical ASP.Net MVC 4.0 application looks like. So I will create a new simple ASP.Net MVC 4.0 Web Application. When I run the application I get the normal page view.Have a look at the picture below.On the left is the mobile view and on the right the normal view. As you can see we have more or less the same content in our mobile application (log in,register) compared with the normal ASP.Net MVC 4.0 application but it is optimised for mobile devices. 4) Let me explain how and when the mobile view is selected and finally rendered.There is a feature in MVC 4.0 that is called Display Modes and with this feature the runtime will select a view.If we have 2 views e.g contact.mobile.cshtml and contact.cshtml in our application the Controller at some point will instruct the runtime to select and render a view named contact.The runtime will look at the browser making the request and will determine if it is a mobile browser or a desktop browser. So if there is a request from my IPhone Safari browser for a particular site, if there is a mobile view the MVC 4.0 will select it and render it. If there is not a mobile view, the normal view will be rendered.5) In the  ASP.Net MVC 4.0 (Internet application) I created earlier (not the first project which was a mobile one) I can run it once more and see how it looks on the browser. If I want to view it with a mobile browser I must download one emulator like Opera Mobile.You can download Opera Mobile hereWhen I run the application I get the same view in both the desktop and the mobile browser. That was to be expected. Have a look at the picture below 6) Then I create another version of the _Layout.mobile.cshtml view in the Shared folder.I simply copy and paste the _Layout.cshtml  into the same folder and then rename it to _Layout.mobile.cshtml and then just alter the contents of the _Layout.mobile.cshtml.When I run again the application I get a different view on the desktop browser and a different one on the Opera mobile browser.Have a look at the picture below ?he Controller will instruct the ASP.Net runtime to select and render a view named _Layout.mobile.cshtml when the request will come from a mobile browser.?he runtime knows that a browser is a mobile one through the ASP.Net browser capability provider. Hope it helps!!!

• Designing an email system to guarantee delivery

  - by GlenH7

  We are looking to expand our use of email for notification purposes. We understand it will generate more inbox volume, but we are being selective about which events we fire notification on in order to keep the signal-to-noise ratio high. The big question we are struggling with is designing a system that guarantees that the email was delivered. If an email isn't delivered, we will consider that an exception event that needs to be investigated. In reality, I say almost guarantees because there aren't any true guarantees with email. We're just looking for a practical solution to making sure the email got there and experiences others have had with the various approaches to guaranteeing delivery. For the TL;DR crowd - how do we go about designing a system to guarantee delivery of emails? What techniques should we consider so we know the emails were delivered? Our biggest area of concern is what techniques to use so that we know when a message is sent out that it either lands in an inbox or it failed and we need to do something else. Additional requirements: We're not at the stage of including an escalation response, but we'll want that in the future or so we think. Most notifications will be internal to our enterprise, but we will have some notifications being sent to external clients. Some of our application is in a hosted environment. We haven't determined if those servers can access our corporate email servers for relaying or if they'll be acting as their own mail servers. Base design / modules (at the moment): A module to assign tracking identification A module to send out emails A module to receive delivery notification (perhaps this is the same as the email module) A module that checks sent messages against delivery notification and alerts on undelivered email. Some references: Atwood: Send some email Email Tracking Some approaches: Request a response (aka read-receipt or Message Disposition Notification). Seems prone to failure since we have cross-compatibility issues due to differing mail servers and software. Return receipt (aka Delivery Status Notification). Not sure if all mail servers honor this request or not Require an action and therefore prove reply. Seems burdensome to force the recipients to perform an additional task not related to resolving the issue. And no, we haven't come up with a way of linking getting the issue fixed to whether or not the email was received. Force a click-through / Other site sign-in. Similar to requiring some sort of action, this seems like an additional burden and will annoy the users. On the other hand, it seems the most likely to guarantee someone received the notification. Hidden image tracking. Not all email providers automatically load the image, and how would we associate the image(s) with the email tracking ID? Outsource delivery. This gets us out of the email business, but goes back to how to guarantee the out-sourcer's receipt and subsequent delivery to the end recipient. As a related concern, there will be an n:n relationship between issue notification and recipients. The 1 issue : n recipients subset isn't as much of a concern although if we had a delivery failure we would want to investigate and fix the core issue. Of bigger concern is n issues : 1 recipient, and we're specifically concerned in making sure that all n issues were received by the recipient. How does forum software or issue tracking software handle this requirement? If a tracking identifier is used, Where is it placed in the email? In the Subject, or the Body?

• Application Demos in UPK

  - by [email protected]

  Over the years, User Productivity Kit has expanded to include solutions to many project challenges. As of UPK 3.6.1, solutions are provided for pre and post application go-live learning, application testing, system documentation, presentation output, and more. New in UPK 3.6.1 are additional features that can be used effectively for application demo purposes. This can come in handy when you need to do a demo but don't want to show or can't show the live application. Maybe you're doing a presentation for a group of project stakeholders and want to focus on the business workflow implemented by the application rather than the mechanics of using it. Or possibly, you need to show the application but you're disconnected from any network preventing you from running the live application. In any of these cases, a presentation aid that represents the live application is what's needed. Previous versions of the UPK topic player would allow you to do this but would always show those UPK user interface elements that help a user learn the application. When you're presenting the narrative live, the UPK bubbles can be a distraction. UPK 3.6.1 provides some new features that allow you to control whether the bubbles display. There are two ways to hide bubbles in a topic. The first is a topic property that allows you to control bubbles across the entire topic. There are 3 settings for the Show Bubbles topic property. The default setting is Use frame settings which allows you to control whether bubbles display on a frame by frame basis. When you choose Always, the bubbles will always display regardless of the frame setting. The final choice is Never. Choosing Never will hide every bubble in your topic with one setting change. As with Always, choosing Never will ignore the frame setting. The second way to control the bubbles is at the frame level. First ensure that the topic's Show Bubbles property is set to Use frame settings. Navigate to the frame on which you want to turn off the bubble and click the Display bubble for this frame button to turn off the bubble. When you play the topic, the bubble will no longer be displayed. Depending on your needs, you might also use another longstanding UPK feature that allows you to control whether the action area displays on a frame. Just click the Action area on/off button to toggle its display. I've found the frame properties to be useful beyond creating presentation aids. When creating "See It!" only topics for more advanced users, I may hide the bubbles on some of the more straightforward frames. For example, if I have a form where one needs to fill out an address, I may display the first bubble in the sequence and explain what the subsequent steps are doing. I then hide bubbles on the remaining frames which are the more mechanical steps of entering the address. We'd like to hear your thoughts on this new UPK feature. Use the comments below to tell us how you've used it. John Zaums Senior Director, Product Development Oracle User Productivity Kit

• What I don&rsquo;t like about WIF&rsquo;s Claims-based Authorization

  - by Your DisplayName here!

  In my last post I wrote about what I like about WIF’s proposed approach to authorization – I also said that I definitely would build upon that infrastructure for my own systems. But implementing such a system is a little harder as it could be. Here’s why (and that’s purely my perspective): First of all WIF’s authorization comes in two “modes” Per-request authorization. When an ASP.NET/WCF request comes in, the registered authorization manager gets called. For SOAP the SOAP action gets passed in. For HTTP requests (ASP.NET, WCF REST) the URL and verb. Imperative authorization This happens when you explicitly call the claims authorization API from within your code. There you have full control over the values for action and resource. In ASP.NET per-request authorization is optional (depends on if you have added the ClaimsAuthorizationHttpModule). In WCF you always get the per-request checks as soon as you register the authorization manager in configuration. I personally prefer the imperative authorization because first of all I don’t believe in URL based authorization. Especially in the times of MVC and routing tables, URLs can be easily changed – but then you also have to adjust your authorization logic every time. Also – you typically need more knowledge than a simple “if user x is allowed to invoke operation x”. One problem I have is, both the per-request calls as well as the standard WIF imperative authorization APIs wrap actions and resources in the same claim type. This makes it hard to distinguish between the two authorization modes in your authorization manager. But you typically need that feature to structure your authorization policy evaluation in a clean way. The second problem (which is somehow related to the first one) is the standard API for interacting with the claims authorization manager. The API comes as an attribute (ClaimsPrincipalPermissionAttribute) as well as a class to use programmatically (ClaimsPrincipalPermission). Both only allow to pass in simple strings (which results in the wrapping with standard claim types mentioned earlier). Both throw a SecurityException when the check fails. The attribute is a code access permission attribute (like PrincipalPermission). That means it will always be invoked regardless how you call the code. This may be exactly what you want, or not. In a unit testing situation (like an MVC controller) you typically want to test the logic in the function – not the security check. The good news is, the WIF API is flexible enough that you can build your own infrastructure around their core. For my own projects I implemented the following extensions: A way to invoke the registered claims authorization manager with more overloads, e.g. with different claim types or a complete AuthorizationContext. A new CAS attribute (with the same calling semantics as the built-in one) with custom claim types. A MVC authorization attribute with custom claim types. A way to use branching – as opposed to catching a SecurityException. I will post the code for these various extensions here – so stay tuned.

• SOA Suite 11g Asynchronous Testing with soapUI

  - by Greg Mally

  Overview The Enterprise Manager test harness that comes bundled with SOA Suite 11g is a great tool for doing smoke tests and some minor load testing. When a more robust testing tool is needed, often times soapUI is leveraged for many reasons ranging from ease of use to cost effective. However, when you want to start doing some more complex testing other than synchronous web services with static content, then the free version of soapUI becomes a bit more challenging. In this blog I will show you how to test asynchronous web services with soapUI free edition. The following assumes that you have a working knowledge of soapUI and will not go into concepts like setting up a project etc. For the basics, please review the documentation for soapUI: http://www.soapui.org/Getting-Started/ Asynchronous Web Service Testing in soapUI When invoking an asynchronous web service, the caller must provide a callback for the response. Since our testing will originate from soapUI, then it is only natural that soapUI would provide the callback mechanism. This mechanism in soapUI is called a MockService. In a nutshell, a soapUI MockService is a simulation of a Web Service (aka, a process listening on a port). We will go through the steps in setting up the MockService for a simple asynchronous BPEL process. After creating your soapUI project based on an asynchronous BPEL process, you will see something like the following: Notice that soapUI created an interface for both the request and the response (i.e., callback). The interface that was created for the callback will be used to create the MockService. Right-click on the callback interface and select the Generate MockService menu item: You will be presented with the Generate MockService dialogue where we will tweak the Path and possibly the port (depends upon what ports are available on the machine where soapUI will be running). We will adjust the Path to include the operation name (append /processResponse in this example) and the port of 8088 is fine: Once the MockService is created, you should have something like the following in soapUI: This window acts as a console/view into the callback process. When the play button is pressed (green triangle in the upper left-hand corner), soapUI will start a process running on the configured Port that will accept web service invocations on the configured Path: At this point we are “almost” ready to try out the asynchronous test. But first we must provide the web service addressing (WS-A) configuration on the request message. We will edit the message for the request interface that was generated when the project was created (SimpleAsyncBPELProcessBinding > process > Request 1 in this example). At the bottom of the request message editor you will find the WS-A configuration by left-clicking on the WS-A label: Here we will setup WS-A by changing the default values to: Must understand: TRUE Add default wsa:Action: Add default wsa:Action (checked) Reply to: ${host where soapUI is running}:${MockService Port}${MockService Path} … in this example: http://192.168.1.181:8088/mockSimpleAsyncBPELProcessCallbackBinding/processResponse We now are ready to run the asynchronous test from soapUI free edition. Make sure that the MockService you created is running and then push the play button for the request (green triangle in the upper left-hand corner of the request editor). If everything is configured correctly, you should see the response show up in the MockService window: To view the response message/payload, just double-click on a response message in the Message Log window of the MockService: At this point you can now expand the project to include a Test Suite for some load balance tests etc. This same topic has been covered in various detail on other sites/blogs, but I wanted to simplify and detail how this is done in the context of SOA Suite 11g. It also serves as a nice introduction to another blog of mine: SOA Suite 11g Dynamic Payload Testing with soapUI Free Edition.

• PetaPoco with parameterised stored procedure and Asp.Net MVC

  - by Jalpesh P. Vadgama

  I have been playing with Micro ORMs as this is very interesting things that are happening in developer communities and I already liked the concept of it. It’s tiny easy to use and can do performance tweaks. PetaPoco is also one of them I have written few blog post about this. In this blog post I have explained How we can use the PetaPoco with stored procedure which are having parameters.  I am going to use same Customer table which I have used in my previous posts. For those who have not read my previous post following is the link for that. Get started with ASP.NET MVC and PetaPoco PetaPoco with stored procedures Now our customer table is ready. So let’s Create a simple process which will fetch a single customer via CustomerId. Following is a code for that. CREATE PROCEDURE mysp_GetCustomer @CustomerId as INT AS SELECT * FROM [dbo].Customer where CustomerId=@CustomerId Now  we are ready with our stored procedures. Now lets create code in CustomerDB class to retrieve single customer like following. using System.Collections.Generic; namespace CodeSimplified.Models { public class CustomerDB { public IEnumerable<Customer> GetCustomers() { var databaseContext = new PetaPoco.Database("MyConnectionString"); databaseContext.EnableAutoSelect = false; return databaseContext.Query<Customer>("exec mysp_GetCustomers"); } public Customer GetCustomer(int customerId) { var databaseContext = new PetaPoco.Database("MyConnectionString"); databaseContext.EnableAutoSelect = false; var customer= databaseContext.SingleOrDefault<Customer>("exec mysp_GetCustomer @customerId",new {customerId}); return customer; } } } Here in above code you can see that I have created a new method call GetCustomer which is having customerId as parameter and then I have written to code to use stored procedure which we have created to fetch customer Information. Here I have set EnableAutoSelect=false because I don’t want to create Select statement automatically I want to use my stored procedure for that. Now Our Customer DB class is ready and now lets create a ActionResult Detail in our controller like following using System.Web.Mvc; namespace CodeSimplified.Controllers { public class HomeController : Controller { public ActionResult Index() { ViewBag.Message = "Welcome to ASP.NET MVC!"; return View(); } public ActionResult About() { return View(); } public ActionResult Customer() { var customerDb = new Models.CustomerDB(); return View(customerDb.GetCustomers()); } public ActionResult Details(int id) { var customerDb = new Models.CustomerDB(); return View(customerDb.GetCustomer(id)); } } } Now Let’s create view based on that ActionResult Details method like following. Now everything is ready let’s test it in browser. So lets first goto customer list like following. Now I am clicking on details for first customer and Let’s see how we can use the stored procedure with parameter to fetch the customer details and below is the output. So that’s it. It’s very easy. Hope you liked it. Stay tuned for more..Happy Programming

• Ubuntu 10.04 & IBM DS3524 with FC multipath, inactive path is [failed][faulty] instead of [active][ghost]

I assume that once I can get that right then the spam in my syslog will end as well. One final thing worth mentioning is that the IBM redbook doc targets SLES 11 so I'm assuming there's something a little different under Ubuntu that I just haven't figured out yet. Update: As suggested by Mitch, I've tried removing /etc/multipath.conf, and now the output of multipath -ll looks like this: root@db06:~# multipath -ll sdg: checker msg is "directio checker reports path is down" sdh: checker msg is "directio checker reports path is down" xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxdm-1 IBM ,1746 FASt [size=4.9T][features=0][hwhandler=0] \_ round-robin 0 [prio=1][active] \_ 5:0:2:0 sde 8:64 [active][ready] \_ round-robin 0 [prio=1][enabled] \_ 5:0:1:0 sdd 8:48 [active][ready] \_ round-robin 0 [prio=0][enabled] \_ 6:0:1:0 sdg 8:96 [failed][faulty] \_ round-robin 0 [prio=0][enabled] \_ 6:0:2:0 sdh 8:112 [failed][faulty] So its more or less the same, with the same message in the syslog every 5 minutes as before, but the grouping has changed.

• Oracle Fusion Procurement Designed for User Productivity

  - by Applications User Experience

  Sean Rice, Manager, Applications User Experience Oracle Fusion Procurement Design Goals In Oracle Fusion Procurement, we set out to create a streamlined user experience based on the way users do their jobs. Oracle has spent hundreds of hours with customers to get to the heart of what users need to do their jobs. By designing a procurement application around user needs, Oracle has crafted a user experience that puts the tools that people need at their fingertips. In Oracle Fusion Procurement, the user experience is designed to provide the user with information that will drive navigation rather than requiring the user to find information. One of our design goals for Oracle Fusion Procurement was to reduce the number of screens and clicks that a user must go through to complete frequently performed tasks. The requisition process in Oracle Fusion Procurement (Figure 1) illustrates how we have streamlined workflows. Oracle Fusion Self-Service Procurement brings together billing metrics, descriptions of the order, justification for the order, a breakdown of the components of the order, and the amount—all in one place. Previous generations of procurement software required the user to navigate to several different pages to gather all of this information. With Oracle Fusion, everything is presented on one page. The result is that users can complete their tasks in less time. The focus is on completing the work, not finding the work. Figure 1. Creating a requisition in Oracle Fusion Self-Service Procurement is a consumer-like shopping experience. Will Oracle Fusion Procurement Increase Productivity? To answer this question, Oracle sought to model how two experts working head to head—one in an existing enterprise application and another in Oracle Fusion Procurement—would perform the same task. We compared Oracle Fusion designs to corresponding existing applications using the keystroke-level modeling (KLM) method. This method is based on years of research at universities such as Carnegie Mellon and research labs like Xerox Palo Alto Research Center. The KLM method breaks tasks into a sequence of operations and uses standardized models to evaluate all of the physical and cognitive actions that a person must take to complete a task: what a user would have to click, how long each click would take (not only the physical action of the click or typing of a letter, but also how long someone would have to think about the page when taking the action), and user interface changes that result from the click. By applying standard time estimates for all of the operators in the task, an estimate of the overall task time is calculated. Task times from the model enable researchers to predict end-user productivity. For the study, we focused on modeling procurement business process task flows that were considered business or mission critical: high-frequency tasks and high-value tasks. The designs evaluated encompassed tasks that are currently performed by employees, professional buyers, suppliers, and sourcing professionals in advanced procurement applications. For each of these flows, we created detailed task scenarios that provided the context for each task, conducted task walk-throughs in both the Oracle Fusion design and the existing application, analyzed and documented the steps and actions required to complete each task, and applied standard time estimates to the operators in each task to estimate overall task completion times. The Results The KLM method predicted that the Oracle Fusion Procurement designs would result in productivity gains in each task, ranging from 13 percent to 38 percent, with an overall productivity gain of 22.5 percent. These performance gains can be attributed to a reduction in the number of clicks and screens needed to complete the tasks. For example, creating a requisition in Oracle Fusion Procurement takes a user through only two screens, while ordering the same item in a previous version requires six screens to complete the task. Modeling user productivity has resulted not only in advances in Oracle Fusion applications, but also in advances in other areas. We leveraged lessons learned from the KLM studies to establish products like Oracle E-Business Suite (EBS). New user experience features in EBS 12.1.3, such as navigational improvements to the main menu, a Google-type search using auto-suggest, embedded analytics, and an in-context list of values tool help to reduce clicks and improve efficiency. For more information about KLM, refer to the Measuring User Productivity blog.

• Create a Search Filter List in Google Chrome

  - by Asian Angel

  Are you tired of unwanted and/or non-relevant results cluttering up the search results at Bing, Yahoo, and Google? With the Search Filter extension for Chrome you can easily remove the unwanted “chaff” from your search results. Note: The extension only works on Bing, Yahoo, and Google at this time. Before For our example we conducted a search for “anime wallpapers” at Yahoo Singapore, Bing Singapore, and Google. In each set of results we decided to focus on results that would display either a yellow or red warning color from WOT. You can see our targeted result for Yahoo Singapore… The one for Bing Singapore… And the targeted result from Google. Search Filter in Action As soon as you install the extension you should take a quick look at the “Options”. At first the “Filters List Area” will be empty but will not remain so for long as you create your own filter list. The second part may or may not be of interest to you…the ability to opt into the filter service. If you opt in your filter list will be connected to your “Google Account” and will be available on any of your Chrome installs with the extension installed (and set to “Opt In”). Keep in mind that if you choose this option the filter list that you create will be aggregated anonymously and have a GUID number attached to it. After installing the extension we refreshed each of our three search pages…notice the small red circle button beside each search result link. Clicking on the red circle button will cause the entire browser window area to “shade out” temporarily while you decide between adding that website to the filter list or cancelling the action. If you add a website to the filter list that result will immediately disappear from the search results list without refreshing the webpage. Looks like we have another website at the bottom that we could add to the filter list… Click, click, click! After adding one website from each of the three search services you can see that our filter list has gotten off to a nice start.

• SQL SERVER – #TechEdIn – Presenting Tomorrow on SQL Server Misconception and Resolution with Vinod Kumar at TechEd India 2012

  - by pinaldave

  I am excited AND nervous at the same time. I am going to present a very interesting topic tomorrow at an SQL Server track in India. This will be my fourth time presenting at TechEd India. So far, I have received so much feedback about this one session. It seems like every single person out there has their own wishes and requests. I am sure that it is going to very challenging experience to satisfy everyone who attends the event through my presentation. Surprise Element Here is the good news: I am going to co-present this session with Vinod Kumar, my long time friend and co-worker. We have known each other for almost four years now, but this is the very first time that we are going to present together on the big stage of TechEd.  When there are more than two presenters, the usual trick is to practice the session multiple times and know exactly what each other is going to present and talk about. However, there’s a catch – we decided to make it different this time and have shared nothing to each other regarding what exactly we are going to present. This makes everything extremely interesting as each of us will be as clueless as the audience when other person is going to talk. Action Item Here are a few of the action items for all of those who are going to attend this session. Vinod and I will be present at the venue 15 minutes before the session. Do come in early and talk with us. We would be glad to talk with you and see if either of us can accommodate your suggestion in our session. If we do, we will give a surprise gift for you. As discussed, this session is going to be a unique two-presenter session. You will have chance to take a side with one speaker and stump the other speaker. Come early to decide which speaker you want to cheer during the session. Quiz and Goodies By now, you must have figured out that this session is going to be an extremely interactive session. We need your support through your active participation. We will have some really brain-twisting quiz line up just for you. You will have to take part and win surprises from us! Trust me. If you get it right, we will give you something which can help you learn more! We will have a quiz on Twitter as well. We will ask a question in person and you will be able to participate on Twitter. 10 – Demos As I said, both of us do not know what each other is going to present, but there are few things which we know very well. We have 10 demos and 6 slides. I think this is going to be an exciting demo marathon. Trust me, you will love it and the taste of this session will be in your mouth till the next TechEd. Session Details Title: SQL Server Misconceptions and Resolution – A Practical Perspective (Add to Calendar) Abstract: “The earth is flat”! – An ancient common misconception, which has been proven incorrect as we progressed in modern times. In this session, we will see various database misconceptions prevailing and their resolutions with the aid of the demos. In this unique session, the audience will be a part of the conversation and resolution. Date and Time: March 21, 2012, 15:15 to 16:15 Location: Hotel Lalit Ashok - Kumara Krupa High Grounds, Bengaluru – 560001, Karnataka, India.

• Web.config WordPress rewrite rules next to Magento

  - by Flo

  I've installed Magento on IIS in folder: E:\mydomain\wwwroot (I already have it all running correctly). I have no deeper folder magento, I placed all files directly in the wwwroot folder, so: wwwroot\app wwwroot\downloader wwwroot\errors wwwroot\includes etc... UPDATE: since I'm on IIS my .htaccess is ignored completely and my web.config rules are used instead. Here's my web.config in folder e:\mydomain\wwwroot: <?xml version="1.0" encoding="UTF-8"?> <configuration> <system.webServer> <rewrite> <rules> <rule name="Magento SEO: remove index.php from URL"> <match url="^(?!index.php)([^?#]*)(\\?([^#]*))?(#(.*))?" /> <conditions> <add input="{URL}" pattern="^/(media|skin|js)/" ignoreCase="false" negate="true" /> <add input="{REQUEST_FILENAME}" matchType="IsFile" ignoreCase="false" negate="true" /> <add input="{REQUEST_FILENAME}" matchType="IsDirectory" ignoreCase="false" negate="true" /> </conditions> <action type="Rewrite" url="index.php/{R:0}" /> </rule> </rules> </rewrite> </system.webServer> </configuration> Next, I wanted to install WordPress. I unzipped all files in folder e:\mydomain\wwwroot\wordpress Browsed to www.mydomain.com/wordpress/wp-admin/install.php, where I configured everything for my database. Everything was installed correctly. I then navigate to http://www.mydomain.com/wordpress/wp-login.php where I type my credentials. I seem to be logged in and am redirected to http://www.mydomain.com/wordpress/wp-admin/ But there I receive an empty page. I enabled detailed error message in IIS following this article: http://www.iis.net/learn/troubleshoot/diagnosing-http-errors/how-to-use-http-detailed-errors-in-iis I also checkec with Fiddler and see that I receive a 500 error: GET /wordpress/wp-admin/ HTTP/1.1 Host: www.mydomain.com Connection: keep-alive Cache-Control: max-age=0 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,/;q=0.8 User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/29.0.1547.76 Safari/537.36 Referer: http://www.mydomain.com/wordpress/wp-login.php Accept-Encoding: gzip,deflate,sdch Accept-Language: en-US,en;q=0.8,nl;q=0.6 Cookie: wordpress_fabec4083cf12d8de89c98e8aef4b7e3=floran%7C1381236774%7C2d8edb4fc6618f290fadb49b035cad31; wordpress_test_cookie=WP+Cookie+check; wordpress_logged_in_fabec4083cf12d8de89c98e8aef4b7e3=floran%7C1381236774%7Cbf822163926b8b8df16d0f1fefb6e02e HTTP/1.1 500 Internal Server Error Content-Type: text/html Server: Microsoft-IIS/7.5 X-Powered-By: PHP/5.4.14 X-Powered-By: ASP.NET Date: Sun, 06 Oct 2013 12:56:03 GMT Content-Length: 0 My WordPress web.config in folder e:\mydomain\wwwroot\wordpress contains: <?xml version="1.0" encoding="UTF-8"?> <configuration> <system.webServer> <rewrite> <rules> <rule name="wordpress" patternSyntax="Wildcard"> <match url="*"/> <conditions> <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true"/> <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true"/> </conditions> <action type="Rewrite" url="index.php"/> </rule></rules> </rewrite> </system.webServer> </configuration> I also want my WordPress articles to be available on www.mydomain.com/blog instead of www.mydomain.com/wordpress Ofcourse my admin links for Magento and Wordpress should also work. How can I configure my web.config files to achieve the above?

• No database selected error in CodeIgniter running on MAMP stack

  - by Apophenia Overload

  First off, does anyone know of a good place to get help with CodeIgniter? The official community forums are somewhat disappointing in terms of getting many responses. I have ci installed on a regular MAMP stack, and I’m working on this tutorial. However, I have only gone through the Created section, and currently I am getting a No database selected error. Model: <?php class submit_model extends Model { function submitForm($school, $district) { $data = array( 'school' => $school, 'district' => $district ); $this->db->insert('your_stats', $data); } } View: <?php $this->load->helper('form'); ?> <?php echo form_open('main'); ?> <p> <?php echo form_input('school'); ?> </p> <p> <?php echo form_input('district'); ?> </p> <p> <?php echo form_submit('submit', 'Submit'); ?> </p> <?php echo form_close(); ?> Controller: <?php class Main extends controller { function index() { // Check if form is submitted if ($this->input->post('submit')) { $school = $this->input->xss_clean($this->input->post('school')); $district = $this->input->xss_clean($this->input->post('district')); $this->load->model('submit_model'); // Add the post $this->submit_model->submitForm($school, $district); } $this->load->view('main_view'); } } database.php $db['default']['hostname'] = "localhost:8889"; $db['default']['username'] = "root"; $db['default']['password'] = "root"; $db['default']['database'] = "stats_test"; $db['default']['dbdriver'] = "mysql"; $db['default']['dbprefix'] = ""; $db['default']['pconnect'] = TRUE; $db['default']['db_debug'] = TRUE; $db['default']['cache_on'] = FALSE; $db['default']['cachedir'] = ""; $db['default']['char_set'] = "utf8"; $db['default']['dbcollat'] = "utf8_general_ci"; config.php $config['base_url'] = "http://localhost:8888/ci/"; ... $config['index_page'] = "index.php"; ... $config['uri_protocol'] = "AUTO"; So, how come it’s giving me this error message? A Database Error Occurred Error Number: 1046 No database selected INSERT INTO `your_stats` (`school`, `district`) VALUES ('TJHSST', 'FairFax') Is there any way for me to test if CodeIgniter can actually detect the mySQL databases I've created with phpMyAdmin in my MAMP stack?

• Validating Petabytes of Data with Regularity and Thoroughness

  - by rickramsey

  by Brian Zents When former Intel CEO Andy Grove said “only the paranoid survive,” he wasn’t necessarily talking about tape storage administrators, but it’s a lesson they’ve learned well. After all, tape storage is the last line of defense to prevent data loss, so tape administrators are extra cautious in making sure their data is secure. Not surprisingly, we are often asked for ways to validate tape media and the files on them. In the past, an administrator could validate the media, but doing so was often tedious or disruptive or both. The debut of the Data Integrity Validation (DIV) and Library Media Validation (LMV) features in the Oracle T10000C drive helped eliminate many of these pains. Also available with the Oracle T10000D drive, these features use hardware-assisted CRC checks that not only ensure the data is written correctly the first time, but also do so much more efficiently. Traditionally, a CRC check takes at least 25 seconds per 4GB file with a 2:1 compression ratio, but the T10000C/D drives can reduce the check to a maximum of nine seconds because the entire check is contained within the drive. No data needs to be sent to a host application. A time savings of at least 64 percent is extremely beneficial over the course of checking an entire 8.5TB T10000D tape. While the DIV and LMV features are better than anything else out there, what storage administrators really need is a way to check petabytes of data with regularity and thoroughness. With the launch of Oracle StorageTek Tape Analytics (STA) 2.0 in April, there is finally a solution that addresses this longstanding need. STA bundles these features into one interface to automate all media validation activities across all Oracle SL3000 and SL8500 tape libraries in an environment. And best of all, the validation process can be associated with the health checks an administrator would be doing already through STA. In fact, STA validates the media based on any of the following policies: Random Selection – Randomly selects media for validation whenever a validation drive in the standalone library or library complex is available. Media Health = Action – Selects media that have had a specified number of successive exchanges resulting in an Exchange Media Health of “Action.” You can specify from one to five exchanges. Media Health = Evaluate – Selects media that have had a specified number of successive exchanges resulting in an Exchange Media Health of “Evaluate.” You can specify from one to five exchanges. Media Health = Monitor – Selects media that have had a specified number of successive exchanges resulting in an Exchange Media Health of “Monitor.” You can specify from one to five exchanges. Extended Period of Non-Use – Selects media that have not had an exchange for a specified number of days. You can specify from 365 to 1,095 days (one to three years). Newly Entered – Selects media that have recently been entered into the library. Bad MIR Detected – Selects media with an exchange resulting in a “Bad MIR Detected” error. A bad media information record (MIR) indicates degraded high-speed access on the media. To avoid disrupting host operations, an administrator designates certain drives for media validation operations. If a host requests a file from media currently being validated, the host’s request takes priority. To ensure that the administrator really knows it is the media that is bad, as opposed to the drive, STA includes drive calibration and qualification features. In addition, validation requests can be re-prioritized or cancelled as needed. To ensure that a specific tape isn’t validated too often, STA prevents a tape from being validated twice within 24 hours via one of the policies described above. A tape can be validated more often if the administrator manually initiates the validation. When the validations are complete, STA reports the results. STA does not report simply a “good” or “bad” status. It also reports if media is even degraded so the administrator can migrate the data before there is a true failure. From that point, the administrators’ paranoia is relieved, as they have the necessary information to make a sound decision about the health of the tapes in their environment.

• Using Managed Beans with your ADF Mobile Client Applications

  - by [email protected]

  Did you know it's easy to extend your ADF Mobile Client application with a Managed Bean just like it is with an ADF web application?  Here's how: Using the New Gallery (File -> New), create a new Java class.  This class should extend oracle.adfnmc.el.utils.BeanResolver.         Add this java class as a managed bean: Go to your task flow, select the Overview tab at the bottom and go to the Managed Bean section.  Add an entry and name your new Managed Bean and point to the java class you just created.        Add your custom methods and properties to your java class   Since reflection is not supported in the J2ME version on some platforms (BlackBerry), you need to provide dispatch code if you want to invoke/access any of your methods/properties from EL.  Here's a sample:  MyBeanClass.java    Use Expression Language (EL) to access your properties and invoke your methods on your MCX pages.  Here's an sample:     <?xml version="1.0" encoding="UTF-8" ?><amc:view xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"          xmlns:amc="http://xmlns.oracle.com/jdev/amc">  <amc:form id="form0">    <amc:menuControl refId="menu0"/>    <amc:panelGroupLayout id="panelGroupLayout1" width="100%">      <amc:panelGroupLayout id="panelGroupLayout2" layout="horizontal"                            width="100%">        <amc:image id="image1" source="logo_sm.png"/>        <amc:outputText value="Home" id="outputText1" verticalAlign="center"                        fontSize="20" fontWeight="bold"                        foregroundColor="#ff0000"/>      </amc:panelGroupLayout>      <amc:commandLink text="#{MyBean.property1}" id="commandLink1"                       actionListener="#{MyBean.doFoo}"                       foregroundColor="#0000ff" action="patientlist"/>    </amc:panelGroupLayout>  </amc:form>  <amc:menu type="main" id="menu0">    <amc:menuGroup id="menuGroup1">      <amc:commandMenuItem id="commandMenuItem1" action="exit" label="Exit"                           index="1" weight="0"/>    </amc:menuGroup>  </amc:menu></amc:view>

• Ubuntu 12.04 / 12.10 Randomly Freezing - nVidia?

  - by Alix Axel

  My Ubuntu install frequently freezes, sometimes showing a black screen (not very common anymore - in my latest installs), some other times the mouse and keyboard just fail to move and respond (not even Ctrl + Alt + F1 works) and some other times I'm able to move the mouse with a huge delay (2-5 seconds) but I'm not able to do/click anything. I have a pretty strong feeling that this problem is related to my graphic card drivers because: after hard reset, I usually get error reports about X.org / jockey it's common for artifacts to appear during loading / shutdown / whenever, for instance: pattern filled with £ during log off ugly-colored squared pattern during boot windows that are partially moved (i.e.: only the top half) Firefox renderings that leave the bottom ~30% of the page black These artifacts appear right before the system freezes. I've installed Ubuntu 12.04 LTS and after several failed attempts to get my dual monitor setup to work properly I tried installing the new 12.10 version, hoping that this new version would have this problem solved... Unfortunatly, that was not the case, so I reverted to Ubuntu 12.04. I've tried all the drivers in the Additional Drivers application (even the experimental ones), I've also tried the nvidia-current package from the PPA repository ubuntu-x-swat/x-updates as well as the nouveau OSS driver. Nothing (except no driver at all with a 640*480 resolution) at all seems stable. Here is the info of my graphic card: alix@alix-E500:~$ lspci | grep VGA 01:00.0 VGA compatible controller: NVIDIA Corporation G86 [GeForce 8400M G] (rev a1) alix@alix-E500:~$ sudo lshw -C video [sudo] password for alix: *-display description: VGA compatible controller product: G86 [GeForce 8400M G] vendor: NVIDIA Corporation physical id: 0 bus info: pci@0000:01:00.0 version: a1 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress vga_controller bus_master cap_list rom configuration: driver=nouveau latency=0 resources: irq:16 memory:fd000000-fdffffff memory:d0000000-dfffffff memory:fa000000-fbffffff ioport:cc00(size=128) memory:fe0e0000-fe0fffff Right now, I don't even have my 22" monitor connected as I can't even get my laptop display to work properly and without freezes. I've searched, read and tried all that I could (over several fresh reinstalls) to fix the problem, but so far, no solution has proven definitive. I'm sorry I can't precise which symptom maps to each driver but I've been trying to solve this one on my own without logging what I'm doing, perhaps someone here will be able to point me to a certain-fix solution, if not I'll keep updating this question as I go along. Please let me know if any more info is needed to pinpoint the exact problem. Trying out NVIDIA accelerated graphics driver (version 173). The scrolling, minimizing / maximizing windows takes between 2 and 5 seconds to finalize. Context menus also pop up very slowly and the typing seems delayed by ~1 second. No critical issues so far. Firefox rendering of the Save Edits button is consistently messed up (random black lines in the top). Trying out NVIDIA accelerated graphics driver (version current) [Recommended]. All the delays mentioned above and the buggy rendering of the Save Edits button are gone, but I'm noticing that the whole screen flashes black for a couple of microseconds and while I was writing this test for the first time, the bottom 30% of the screen went black and I couldn't do anything (not even Ctrl + Alt + F1 would work). Had to force a hard reset. Also, the system hanged a little for a couple of seconds with the fade out of the "Restart" menu. Trying out NVIDIA accelerated graphics driver (*experimental*beta) (version experimental-304). Same symptoms as before, it crashed once while I was trying to install Chromium and again after a hard reset when I was trying to remove the driver. The bottom of the screen did not went black and I could move my mouse both times. Ctrl + Alt + F1 didn't work. The ugly-colored pattern also showed up during the second boot. Trying out NVIDIA accelerated graphics driver (*experimental*beta) (version experimental-307). The system crashed as soon as I clicked something. Had to do a fresh re-install. Trying out Nouveau: Accelerated Open Source driver for nVidia cards. Artifacts still show up during boot but other than that this one seems stable. As soon as I connected my second monitor, the responsiveness dropped a lot, animations and video are somewhat slow. I'm gonna try this solution http://askubuntu.com/a/98871/9018 later on.

• Why you need to tag your build servers in TFS

  - by Martin Hinshelwood

  At SSW we use gated check-in for all of our projects. The benefits are based on the number of developers you have working on your project. Lets say you have 30 developers and each developer breaks the build once per month. That could mean that you have a broken build every day! Gated check-ins help, but they have a down side that manifests as queued builds and moaning developers. The way to combat this is to have more build servers, but with that comes complexity. Inevitably you will need to install components that you would expect to be installed on target computers, but how do you keep track of which build servers have which bits? What about a geographically diverse team? If you have a centrally controlled infrastructure you might have build servers in multiple regions and you don’t want teams in Sydney copying files from Beijing and vice a versa on a regular basis. So, what is the answer. Its Tags. You can add a set of Tags to your agents and then set which tags to look for in the build definition. Figure: Open up your Build Controller Manager Select “Build | Manage Build Controllers…” to get a list of all of your controllers and he build agents that are associated with them. Figure: the list of build agents and their controllers Each of these Agents might be subtly different. For example only one of these agents has FTP software installed. This software is required for only one of the many builds we have set up. My ethos for build servers is to keep them as clean as possible and not to install anything that is not absolutely necessary. For me that means anything that does not add a *.target file is suspect, and should really be under version control and called via the command line from there. So, some of the things you may install are: Silverlight 4 SDK Visual Studio 2010 Visual Studio 2008 WIX etc You should not install things that will not end up on the target users computer. For a website that means something different to a client than to a server, but I am sure you get the idea. One thing you can do to make things easier is to create a tag for each of the things that you install. that way developers can find the things they need. We may change to using a more generic tagging structure (Like “Web Application” or “WinForms Application”) if this gets too unwieldy, but for now the list of tags is limited. Figure: Tags associated with one of our build agents Once you have your Build Agents all tagged up ALL your builds will start to fail This is because the default setting for a build is to look for an Agent that exactly matches the tags for the build, and we have not added any yet. The quick way to fix this is to change the “Tag Comparison Operator” from “ExactMatch” to “MatchAtLease” to get your build immediately working. Figure: Tag Comparison Operator changes to MatchAtLeast to get builds to run. The next thing to do is look for specific tags. You just select from the list of available tags and the controller will make sure you get to a build agent that uses them. Figure: I want Silverlight, VS2010 and WIX, but do not care about Location. And there you go, you can now have build agents for different purposes and regions within the same environment. You can also use name filtering, so if you have a good Agent naming convention you can filter by that for regions. For example, your Agents might be “SYDVMAPTFSBP01” and “SYDVMAPTFSBP02” so a name filter of “SYD*” would target all of the Sydney build agents. Figure: Agent names can be used for filtering as well This flexibility will allow you to build better software by reducing the likelihood of not having a certain dependency on the target machines. Figure: Setting the name filter based on server location  Used in combination there is a lot of power here to coordinate tens of build servers for multiple projects across multiple regions so your developers get the most out of your environment.

• Serving up a RSS feed in MVC using WCF Syndication

  - by brian_ritchie

  With .NET 3.5, Microsoft added the SyndicationFeed class to WCF for generating ATOM 1.0 & RSS 2.0 feeds.  In .NET 3.5, it lives in System.ServiceModel.Web but was moved into System.ServiceModel in .NET 4.0. Here's some sample code on constructing a feed: .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: Consolas, "Courier New", Courier, Monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } 1: SyndicationFeed feed = new SyndicationFeed(title, description, new Uri(link)); 2: feed.Categories.Add(new SyndicationCategory(category)); 3: feed.Copyright = new TextSyndicationContent(copyright); 4: feed.Language = "en-us"; 5: feed.Copyright = new TextSyndicationContent(DateTime.Now.Year + " " + ownerName); 6: feed.ImageUrl = new Uri(imageUrl); 7: feed.LastUpdatedTime = DateTime.Now; 8: feed.Authors.Add(new SyndicationPerson() { Name = ownerName, Email = ownerEmail }); 9:   10: var feedItems = new List<SyndicationItem>(); 11: foreach (var item in Items) 12: { 13: var sItem = new SyndicationItem(item.title, null, new Uri(link)); 14: sItem.Summary = new TextSyndicationContent(item.summary); 15: sItem.Id = item.id; 16: if (item.publishedDate != null) 17: sItem.PublishDate = (DateTimeOffset)item.publishedDate; 18: sItem.Links.Add(new SyndicationLink() { Title = item.title, Uri = new Uri(link), Length = item.size, MediaType = item.mediaType }); 19: feedItems.Add(sItem); 20: } 21: feed.Items = feedItems;   Then, we create a custom ContentResult to serialize the feed & stream it to the client: 1: public class SyndicationFeedResult : ContentResult 2: { 3: public SyndicationFeedResult(SyndicationFeed feed) 4: : base() 5: { 6: using (var memstream = new MemoryStream()) 7: using (var writer = new XmlTextWriter(memstream, System.Text.UTF8Encoding.UTF8)) 8: { 9: feed.SaveAsRss20(writer); 10: writer.Flush(); 11: memstream.Position = 0; 12: Content = new StreamReader(memstream).ReadToEnd(); 13: ContentType = "application/rss+xml" ; 14: } 15: } 16: } Finally, we wire it up through the controller: 1: public class RssController : Controller 2: { 3: public SyndicationFeedResult Feed() 4: { 5: var feed = new SyndicationFeed(); 6: // populate feed... 7: return new SyndicationFeedResult(feed); 8: } 9: }   In the next post, I'll discuss how to add iTunes markup to the feed to publish it on iTunes as a Podcast.

• Hello, T4MVC &ndash; Goodbye, ASP.NET MVC &ldquo;magic strings&rdquo;

  - by Brian Schroer

  I’m working on my first ASP.NET MVC project, and I really, really like MVC. I hate all of the “magic strings”, though: <div id="logindisplay"> <% Html.RenderPartial("LogOnUserControl"); %> </div> <div id="menucontainer"> <ul id="menu"> <li><%=Html.ActionLink("Find Dinner", "Index", "Dinners")%></li> <li><%=Html.ActionLink("Host Dinner", "Create", "Dinners")%></li> <li><%=Html.ActionLink("About", "About", "Home")%></li> </ul> </div> They’re prone to misspelling (causing errors that won’t be caught until runtime), there’s duplication, there’s no Intellisense, and they’re not friendly to refactoring tools.   I had started down the path of creating static classes with constants for the strings, e.g.: <li><%=Html.ActionLink("Find Dinner", DinnerControllerActions.Index, Controllers.Dinner)%></li> …but that was pretty tedious.   Then I discovered T4MVC (http://mvccontrib.codeplex.com/wikipage?title=T4MVC). Just add its T4MVC.tt and T4MVC.settings.t4 files to the root of your MVC application, and it magically (and this time, it’s good magic) generates code that allows you to replace the first code sample above with this: <div id="logindisplay"> <% Html.RenderPartial(MVC.Shared.Views.LogOnUserControl); %> </div> <div id="menucontainer"> <ul id="menu"> <li><%=Html.ActionLink("Find Dinner", MVC.Dinners.Index())%></li> <li><%=Html.ActionLink("Host Dinner", MVC.Dinners.Create())%></li> <li><%=Html.ActionLink("About", MVC.Home.About())%></li> </ul> </div> It gives you a strongly-typed alternative to magic strings for all of these scenarios: Html.Action Html.ActionLink Html.RenderAction Html.RenderPartial Html.BeginForm Url.Action Ajax.ActionLink view names inside controllers But wait, there’s more! It even gives you static helpers for image and script links, e.g.: <img src="<%= Links.Content.nerd_jpg %>" />   <script src="<%= Links.Scripts.Map_js %>" type="text/javascript"></script> …instead of: <img src="/Content/nerd.jpg" />   <script src="/Scripts/Map.js" type="text/javascript"></script>   Thanks to David Ebbo for creating this great tool. You can watch an eight and a half minute video about T4MVC on Channel 9 via this link: http://channel9.msdn.com/posts/jongalloway/Jon-Takes-Five-with-David-Ebbo-on-T4MVC/. You can download T4MVC from its CodePlex page: http://mvccontrib.codeplex.com/wikipage?title=T4MVC.

• Monitor SQL Server Replication Jobs

  - by Yaniv Etrogi

  The Replication infrastructure in SQL Server is implemented using SQL Server Agent to execute the various components involved in the form of a job (e.g. LogReader agent job, Distribution agent job, Merge agent job) SQL Server jobs execute a binary executable file which is basically C++ code. You can download all the scripts for this article here SQL Server Job Schedules By default each of job has only one schedule that is set to Start automatically when SQL Server Agent starts. This schedule ensures that when ever the SQL Server Agent service is started all the replication components are also put into action. This is OK and makes sense but there is one problem with this default configuration that needs improvement  -  if for any reason one of the components fails it remains down in a stopped state.   Unless you monitor the status of each component you will typically get to know about such a failure from a customer complaint as a result of missing data or data that is not up to date at the subscriber level. Furthermore, having any of these components in a stopped state can lead to more severe problems if not corrected within a short time. The action required to improve on this default settings is in fact very simple. Adding a second schedule that is set as a Daily Reoccurring schedule which runs every 1 minute does the trick. SQL Server Agent’s scheduler module knows how to handle overlapping schedules so if the job is already being executed by another schedule it will not get executed again at the same time. So, in the event of a failure the failed job remains down for at most 60 seconds. Many DBAs are not aware of this capability and so search for more complex solutions such as having an additional dedicated job running an external code in VBS or another scripting language that detects replication jobs in a stopped state and starts them but there is no need to seek such external solutions when what is needed can be accomplished by T-SQL code. SQL Server Jobs Status In addition to the 1 minute schedule we also want to ensure that key components in the replication are enabled so I can search for those components by their Category, and set their status to enabled in case they are disabled, by executing the stored procedure MonitorEnableReplicationAgents. The jobs that I typically have handled are listed below but you may want to extend this, so below is the query to return all jobs along with their category. SELECT category_id, name FROM msdb.dbo.syscategories ORDER BY category_id; Distribution Cleanup LogReader Agent Distribution Agent Snapshot Agent Jobs By default when a publication is created, a snapshot agent job also gets created with a daily schedule. I see more organizations where the snapshot agent job does not need to be executed automatically by the SQL Server Agent  scheduler than organizations who   need a new snapshot generated automatically. To assure this setting is in place I created the stored procedure MonitorSnapshotAgentsSchedules which disables snapshot agent jobs and also deletes the job schedule. It is worth mentioning that when the publication property immediate_sync is turned off then the snapshot files are not created when the Snapshot agent is executed by the job. You control this property when the publication is created with a parameter called @immediate_sync passed to sp_addpublication and for an existing publication you can use sp_changepublication. Implementation The scripts assume the existence of a database named PerfDB. Steps: Run the scripts to create the stored procedures in the PerfDB database. Create a job that executes the stored procedures every hour. -- Verify that the 1_Minute schedule exists. EXEC PerfDB.dbo.MonitorReplicationAgentsSchedules @CategoryId = 10; /* Distribution */ EXEC PerfDB.dbo.MonitorReplicationAgentsSchedules @CategoryId = 13; /* LogReader */ -- Verify all replication agents are enabled. EXEC PerfDB.dbo.MonitorEnableReplicationAgents @CategoryId = 10; /* Distribution */ EXEC PerfDB.dbo.MonitorEnableReplicationAgents @CategoryId = 13; /* LogReader */ EXEC PerfDB.dbo.MonitorEnableReplicationAgents @CategoryId = 11; /* Distribution clean up */ -- Verify that Snapshot agents are disabled and have no schedule EXEC PerfDB.dbo.MonitorSnapshotAgentsSchedules; Want to read more of about replication?

• Too Clever for My Own Good

  - by AjarnMark

  Yesterday I caught myself being a little too clever for my own good with some ASP.NET code.  It seems that I have forgotten some of my good old classic HTML and JavaScript skills, and become too dependent on the .NET Framework and WebControls to do the work for me.  Here’s the scenario… In order to improve the User Interface and better communicate to the user when something is happening that they need to wait for, we have started to modify some of our larger (slower) pages to display messages like Processing… or Reloading… while they are cycling through a postback.  (Yes, I understand this could be improved by using AJAX / Callbacks and so on, but even then, you need to let your user know that they need to wait for that section to be re-rendered, so for the moment these pages will continue to use good ol’ Postbacks.)  It’s a very simple trick, really.  All I want to do is when some control triggers a postback, first run a little client-side JavaScript to hide the main contents of the page (such as a GridView) and display the appropriate message.  This lets the user know, “Hey, we’re doing something, don’t click another link or scroll and try to take action right now.” The first places I hooked this up were easy.  Most common cause of a postback:  Buttons.  And when you’re writing the markup or declarative code for an ASP:Button control, there is the handy OnClientClick property which is designed for just this purpose…to run client-side JavaScript before the postback occurs.  This is distinguished from the OnClick property which tells the control what Server-side code to run.  Great!  Done!  Easy! But then there are other controls like DropDownLists and CheckBoxes that we use on our pages with the AutoPostback=True setting which cause postbacks.  And these don’t have OnClientClick or OnClientSelectedIndexChanged events.  So I started getting creative, using an ASP:CustomValidator control in conjunction with setting the CausesValidation and ValidationGroup settings on these controls, which basically caused the action on the control to fire the Custom Validator, which was defined with a Client Side validation function which then did the hide content/show message code (and return a meaningless IsValid setting).  This also caused me to define a different ValidationGroup setting for my real data entry validator controls so that I could control them separately and only have them fire when I really wanted validation, and not just my show/hide trick. For a little while I was pretty proud of myself for coming up with this clever approach to get around what I considered to be a serious oversight on the DropDownList and CheckBox controls declarative syntax.  Then, in the midst of my smugness, just as I was about to commit my changes to the source code repository, it dawned on me that there is a much simpler and much more appropriate way to accomplish this.  All that I really needed to do was to put in my server-side code (I used the Page_Init section) a call to MyControl.Attributes.Add(“onClick”, “myJavaScriptFunctionName()”) for the checkboxes, and for the DropDownLists (which become select tags) use “onChange” instead of “onClick”.  This is exactly the type of thing that the Attributes collection is there for…so you can add attributes to be rendered with the control that you would have otherwise stuck right into the HTML markup if you had been doing this by hand in the first place. Ugh!  A few hours wasted on clever tricks that I ended up completely removing, but I did learn a lot more about custom validators and validation groups in the process.  And got a good reminder that all that stuff (HTML, JavaScript, and CSS) I learned back when I wrote classic ASP pages is still valuable today.  Oh, and one more thing…don’t get lulled into too much reliance on the the whiz-bang tool to do it for you.  After all, WebControls are just another layer of abstraction, and sometimes you need to dig down through the layers and get a little closer to the native language.

The company has accomplished a lot in ten years overcoming a number of hurdles and challenges to have grown organically to a 150+ person global company with offices in the US, UK, and India and customers in the US, Canada, and Europe. Now more than ever with the current global landscape from an economic and competitive standpoint it was vital that we make some changes to remain successful for the next ten years. There were two key initiatives that we discussed internally that would enable us to successfully accomplish this – collaboration and the concept of “insight to action”. With our existing Oracle CRM On Demand platform we had components of this but not the full depth and breadth that we were looking for. When we started to discuss Fusion CRM we immediately saw several next generation tools that would embrace these two objectives. For a consulting and development organization the collaboration required between business development and consulting delivery is as important as the collaboration required during the projects between the project delivery and account management teams. The Activity Streams functionality in Fusion CRM immediately addressed the communication of key discussion topics and exchanges around our clients. Of course when we saw the Oracle Social Network (which is part of our Fusion CRM roadmap) we were blown away. The combination OSN and our CRM is going to make us more effective as we discuss and work cohesively on client engagements – ensuring mutual success for both Athene and our clients. When we looked at “insight to action” we saw that we had a great platform when folks were at their desks, unfortunately a lot of our business development and consulting folks are on the road. The Fusion Mobile Sales and Fusion Outlook Desktop provide information to our teams when they are on the go. So that they can provide real-time information and react to real-time information provided by their peers. We are in the early stages of our transformative experience with Fusion CRM but we believe the platform along with our people and processes are going to help us achieve our goals in the future.

• AWS .NET SDK v2: setting up queues and topics

  - by Elton Stoneman

  Originally posted on: http://geekswithblogs.net/EltonStoneman/archive/2013/10/13/aws-.net-sdk-v2-setting-up-queues-and-topics.aspxFollowing on from my last post, reading from SQS queues with the new SDK is easy stuff, but linking a Simple Notification Service topic to an SQS queue is a bit more involved. The AWS model for topics and subscriptions is a bit more advanced than in Azure Service Bus. SNS lets you have subscribers on multiple different channels, so you can send a message which gets relayed to email address, mobile apps and SQS queues all in one go. As the topic owner, when you request a subscription on any channel, the owner needs to confirm they’re happy for you to send them messages. With email subscriptions, the user gets a confirmation request from Amazon which they need to reply to before they start getting messages. With SQS, you need to grant the topic permission to write to the queue. If you own both the topic and the queue, you can do it all in code with the .NET SDK. Let’s say you want to create a new topic, a new queue as a topic subscriber, and link the two together. Creating the topic is easy with the SNS client (which has an expanded name, AmazonSimpleNotificationServiceClient, compare to the SQS class which is just called QueueClient): var request = new CreateTopicRequest(); request.Name = TopicName; var response = _snsClient.CreateTopic(request); TopicArn = response.TopicArn; In the response from AWS (which I’m assuming is successful), you get an ARN – Amazon Resource Name – which is the unique identifier for the topic. We create the queue using the same code from my last post, AWS .NET SDK v2: the message-pump pattern, and then we need to subscribe the queue to the topic. The topic creates the subscription request: var response = _snsClient.Subscribe(new SubscribeRequest { TopicArn = TopicArn, Protocol = "sqs", Endpoint = _queueClient.QueueArn }); That response will give you an ARN for the subscription, which you’ll need if you want to set attributes like RawMessageDelivery. Then the SQS client needs to confirm the subscription by allowing the topic to send messages to it. The SDK doesn’t give you a nice mechanism for doing that, so I’ve extended my AWS wrapper with a method that encapsulates it: internal void AllowSnsToSendMessages(TopicClient topicClient) { var policy = Policies.AllowSendFormat.Replace("%QueueArn%", QueueArn).Replace("%TopicArn%", topicClient.TopicArn); var request = new SetQueueAttributesRequest(); request.Attributes.Add("Policy", policy); request.QueueUrl = QueueUrl; var response = _sqsClient.SetQueueAttributes(request); } That builds up a policy statement, which gets added to the queue as an attribute, and specifies that the topic is allowed to send messages to the queue. The statement itself is a JSON block which contains the ARN of the queue, the ARN of the topic, and an Allow effect for the sqs:SendMessage action: public const string AllowSendFormat= @"{ ""Statement"": [ { ""Sid"": ""MySQSPolicy001"", ""Effect"": ""Allow"", ""Principal"": { ""AWS"": ""*"" }, ""Action"": ""sqs:SendMessage"", ""Resource"": ""%QueueArn%"", ""Condition"": { ""ArnEquals"": { ""aws:SourceArn"": ""%TopicArn%"" } } } ] }"; There’s a new gist with an updated QueueClient and a new TopicClient here: Wrappers for the SQS and SNS clients in the AWS SDK for .NET v2. Both clients have an Ensure() method which creates the resource, so if you want to create a topic and a subscription you can use:  var topicClient = new TopicClient(“BigNews”, “ImListening”); And the topic client has a Subscribe() method, which calls into the message pump on the queue client: topicClient.Subscribe(x=>Log.Debug(x.Body)); var message = {}; //etc. topicClient.Publish(message); So you can isolate all the fiddly bits and use SQS and SNS with a similar interface to the Azure SDK.

• SQL SERVER – #TechEdIn – Presenting Tomorrow on Speed Up! – Parallel Processes and Unparalleled Performance at TechEd India 2012

  - by pinaldave

  Performance tuning is always a very hot topic when it is about SQL Server. SQL Server Performance Tuning is a very challenging subject that requires expertise in Database Administration and Database Development. I always have enjoyed talking about SQL Server Performance tuning subject. However, in India, it’s actually the very first time someone is presenting on this interesting subject, so this time I had the biggest challenge to present this session. Frequently enough, we get these two kind of questions: How to turn off parallelism as it is reducing performance? How to turn on parallelism as I want more performance? The reality is that not everyone knows what exactly is needed by their system. In this session, I have attempted to answer this very question. I’ve decided to provide a balanced view but stay away from theory, which leads us to say “It depends”. The session will have a clear message about this towards its end. Deck Details Slides: 45+ Demos: 7+ Bonus Quiz: 5 Images: 10+ Session delivery time: 52 Mins + 8 Mins of Q & A I have presented this session a couple of times to my friends and so far have received good feedback. Oftentimes, when people hear that I am going to present 45 slides, they all say it is too much to cover. However, when I am done with the session the usual reaction is that I truly gave justice to those slides. Action Item Here are a few of the action items for all of those who are going to attend this session: If you want to attend the session, just come early. There’s a good chance that you may not get a seat because right before me, there is a session from SQL Guru Vinod Kumar. He performs a powerful delivery of million concepts in just a little time. Quiz. I will be asking few questions during the session as well as before the session starts. If you get the correct answer, I will give unique learning material for you. You may not want to miss this learning opportunity at any cosst. Session Details Title: Speed Up! – Parallel Processes and Unparalleled Performance (Add to Calendar) Abstract: “More CPU, More Performance” – A  very common understanding is that usage of multiple CPUs can improve the performance of the query. To get a maximum performance out of any query, one has to master various aspects of the parallel processes. In this deep-dive session, we will explore this complex subject with a very simple interactive demo. Attendees will walk away with proper understanding of CX_PACKET wait types, MAXDOP, parallelism threshold and various other concepts. Date and Time: March 23, 2012, 12:15 to 13:15 Location: Hotel Lalit Ashok - Kumara Krupa High Grounds, Bengaluru – 560001, Karnataka, India.
