SQL 2014 Hosting : New Feature of SQL server 2014

clock September 9, 2013 08:28 by author herry

Microsoft SQL Server 2014 builds on the mission-critical capabilities delivered in the prior release by providing breakthrough performance, availability and manageability for your mission critical applications. SQL Server 2014 delivers new in-memory capabilities built into the core database for OLTP and data warehousing, which complement our existing in-memory data warehousing and BI capabilities for the most comprehensive in-memory database solution in the market.

SQL Server 2014 also provides new disaster recovery and backup solutions with Windows Azure, enabling customers to use their existing skills with the on-premises product offerings to take advantage of Microsoft’s global datacenters. In addition, SQL Server 2014 takes advantage of new Windows Server 2012 and Windows Server 2012 R2 capabilities to give you unparalleled scalability for your database application in a physical or virtual environment.

Here are some of the notable new features in SQL Server 2014

Performance
Several new features have been introduced to improve database performance.

In-Memory OLTP. 
This is a new feature which can help resolve issues in high concurrency situations.
the new In-Memory OLTP Engine (formerly code-named Hekaton) will provide OLTP performance improvements by moving selected tables into memory. The In-memory OTLP Engine works with commodity hardware and won’t require any application code changes.  There are some requirements to get it working but for those whose problem this solves, it is very cool.

Updatable ColumnStore Indexes.
This provides the ability to load or delete data from existing ColumnStore indexes. Previously once a ColumnStore index was created you could not directly add, delete, or modify data in the table. In order to update table information the index needed to be dropped or disabled and then the index rebuilt.

Buffer Pool Extension to Solid State Drives (SSDs).
This is new functionality providing the ability of each node to have its own SSD or SSD Array for buffering, and thus performance capabilities can be greatly increased.
Resource Management. Along with CPU and Memory management which were already available in SQL Server, SQL Server 2014 adds the ability to control the IO usage for a resource pool.
Improved Query Performance. Another new feature for performance improvement wherein query processing has been enhanced and split into a two-step process: decision making and execution.

Improved Integration with Windows Server 2012
SQL Server 2014 will also provide support for Windows Server 2012’s new Storage Spaces feature. Storage Spaces enables you to create pools of tiered storage that can improve application availability and performance. SQL Server 2014’s Resource Governor can take advantage of Windows Server 2012’s automated storage tiering. Plus, you can use the Resource Governor to manage and limit application IO utilization.

Scalability & High Availability
AlwaysOn Secondaries. Provides for up-to eight secondaries (double the 2012 option).
More Reliable Secondaries. Previously several factors could result in secondaries being dropped offline. Those areas have been addressed.
Scale to the Cloud. SQL 2014 allows for Hybrid systems as you can now use Azure VMs as AlwaysOn AG replicas.

Improved Backup Options
Backup to Azure. With this new feature of backup to Azure, backups can be stored offsite (in the cloud) providing safe storage of backup data.
Smart Backup to Azure. Another new backup feature is Smart Backups. With Smart Backups SQL Server determines whether a full or incremental backup is needed and backs up accordingly to Azure.   

In summary
Microsoft has upped the ante again in the database arena providing more features, scalability and capability. The improved features in 2014 combined with their other database offerings such as HD Insight (Hadoop) and the high-performance PDW make for an impressive array of data offerings for companies both large and small.

WebSocket Hosting in Windows Server 2012 with ASPHostCentral.com

clock November 28, 2012 07:15 by author Administrator

As both the WebSocket Protocol and the WebSocket API gain full-fledged support in the Windows 8 Consumer preview, ASP.NET developers can start taking advantage of the bidirectional capabilities by using System.Web.WebSockets library.

ASPHostCentral.com, as the premier provider of ASP.NET and Windows Hosting service, proudly announces that we have supported the latest Windows Server 2012. This Windows Server version does support WebSocket technology and ASP.NET developers can maximize this opportunity directly.

In the Windows 8 consumer preview and Server beta, IE10 and all other Microsoft WebSocket client and server features now support the final version of the IETF WebSocket Protocol. In addition, IE10 implements the W3C WebSocket API Candidate Recommendation. An article on the IE team blog explains this in much more detail.

Meanwhile, ASP.NET Developers can start using the System.Web.WebSockets library introduced in .NET Framework 4.5 to leverage this technology. Note that this is different from the System.Net.WebSockets namespace which contains the actual implementation of the WebSocket standard in .NET – System.Web.WebSockets provides the integration of this implementation with ASP.NET.

WebSocket is a technology for providing bi-directional communication channels over a single TCP socket. This is a much simpler alternative to using Comet Channels to allow the web server to push data to a web client, without the client explicitly requesting it. Although the technology itself has been available since much earlier (Google Chrome first announced support for it in late 2009), it finally became a Proposed Standard last December essentially receiving a nod from the Internet Engineering Task Force.



Node.js hosting on Windows Server 2012 with ASPHostCentral.com

clock November 26, 2012 08:17 by author Administrator

Node.js is a server side software system designed for writing scalable Internet applications, notably web servers. Programs are written on the server side in JavaScript, using event-driven, asynchronous I/O to minimize overhead and maximize scalability.

ASPHostCentral.com opens an opportunity to everyone to host their website with Node.js on our Windows 2012 web server. You can always start from our cheapest Standard Plan @$4.49/month to have your site hosted on our environment.

Node.js Background and Details

Node.js consists of Google's V8 JavaScript engine, libUV, and several built-in libraries.

Node.js was created by Ryan Dahl starting in 2009, and its growth is sponsored by Joyent, his employer.

Dahl's original goal was to create the ability to make web sites with push capabilities as seen in web applications like Gmail. After trying solutions in several other programming languages he chose JavaScript because of the lack of an existing I/O API. This allowed him to define a convention of non-blocking, event-driven I/O.

Similar environments written in other programming languages include Twisted for Python, Perl Object Environment for Perl, libevent for C, Vert.x for Java and EventMachine for Ruby. Unlike most JavaScript programs, it is not executed in a web browser, but is instead a server-side JavaScript application. Node.js implements some CommonJS specifications. It provides a REPL environment for interactive testing.

Working with WebSockets in WCF 4.5

clock November 24, 2012 07:06 by author Administrator

Web Services have one great virtue: they're completely interoperable. They also have one great failing: in order to be interoperable, Web Services use a set of technologies that are guaranteed to give you, at best, adequate performance. Fortunately, WCF 4.5 has a solution: support for WebSockets.

Ever since Web Services appeared, developers have been trying to make them run faster. REST and JSON can be seen as a way of speeding things up by reducing the overhead in the messaging format used by Web Services. However, even with REST and JSON you're still moving and parsing text, which is the bulkiest and slowest data transfer mechanism; you'd get better performance if you could move binary data around. And REST and JSON don't tackle another reason for why Web Services give poor performance: HTTP, the network protocol used by Web Services. There are slower protocols than HTTP around, but no one is using them.

But performance isn't the only issue that using HTTP creates: HTTP in Web Services is tied to a request/response cycle. The reason Ajax applications make all their requests asynchronously is because if you call a service that takes a long time to complete, your request has to wait for that response before you can get your result.

On top of that, if your service has something else to tell your client after that initial response (an ongoing set of updates, for instance), then either your client has to make repeated polling calls to the service to get the result (another performance burden) or, in a non-Ajax application, you have to set up a complementary Web Service that the service can call with the updates.

A far better arrangement would be for the client to submit its request in a "fire and forget" kind of arrangement and then for the service to call back to the client when it has the data (and keep calling back if there are updates to send).

WebSockets addresses all of those issues, while still being an industry standard and therefore interoperable (confusions in vendor's implementations of the standard may interfere). In fact, your browser probably already supports WebSockets.

For most processing, WebSockets uses TCP to communicate, giving you the benefit of a faster protocol. WebSockets also supports sending both binary (for speed) and text (for interoperability). But in many ways, the best part of WebSockets is that it supports two-way communication: The client can call the service just to open communication; and after that, the service can call the client whenever it has information to share. And WCF 4.5 provides support for WebSockets.

So in the next few columns, I'm going to look at WebSockets in WCF 4.5. I'll look at the two ways you can implement WebSockets (one complicated and flexible, one simpler and less flexible) and create client a JavaScript client. Along the way I'll also discuss some of the issues you should consider in creating a WebSocket application.

Configuring the Server

One warning: You may not be able to use the code in this series, yet. As I write this (April 2012), WebSockets is only supported on Windows 8 (I worked on the 64-bit beta ISO for Windows 8 Server); even then, you'll need to configure Windows 8 to support WebSockets.

To configure Windows 8, in Server Manager, from the Manage menu, run the Add Server Roles and Features wizard. In the Wizard, you'll need to add the Web Server (IIS) role. After that, under Features, select ASP.NET 4.5 (if it isn't already selected) and, under Web Services, select HTTP Activation. Finally, under Web Services (IIS)/Role Services, select WebSockets. After  finishinb the Wizard, select Local Server and set IIS Enhanced Security Configuration to off.

To work with WCF 4.5, you'll need Visual Studio 11 (again, in beta, as I write this). The first time you run it, Visual Studio 11 will probably offer to download an update; if so, take the update (I took the update and I won't guarantee that the following code will work without it).

Second warning: This may be a frustrating set of columns if you're reading them as soon as I post them. I've got a fair amount of ground to cover so, in this column, I'll only be setting up to write the code that a WebSocket service requires. But hang tough; the next column will have the code and subsequent columns will show you how to build the clients and provide an alternative way to build a WebSocket service.

Building the Service

I did my testing with a WCF Service Application Project. To take advantage of IIS's support for WebSockets that I'd just finished configuring, I went to the Web tab of my Project Properties and unchecked the Use IIS Express option so that I was testing with the "real" IIS.

Once you've set up your server and project, the first step in creating your WebSocket service is to define two interfaces: one with a single method that accepts requests from clients and another interface with a single method to send results.

For the first interface, I'll define a method that accepts an Order Id (I call the method OrderStatusById method and the interface IRequestOrderStatusUpdates). In the ServiceContract attribute on the interface that accepts requests, you need to use the attribute's CallbackContract to specify the second interface (the one with the method used to send data back to the client is ISendOrderStatus in this example). The method must accept a Message as its only input parameter and the method's OperationContract attribute must set its IsOneWay property to True and its Action property to an asterisk.

The result for my Order status example looks like this:

<ServiceContract(CallbackContract:=GetType(ISendOrderStatus))>
Public Interface IRequestOrderStatusUpdate

  <OperationContract(IsOneWay:=True, Action:="*")>
  Sub OrderStatusByID(OrderStatusMessage  As Channels.Message)

End Interface

The definition for the return method is similar, except that you don't need any special specifications for the ServiceContract attribute. I've called my method SendOrderStatus:

<ServiceContract()>
Public Interface ISendOrderStatus

  <OperationContract(IsOneWay:=True, Action:="*")>
  Sub SendOrderStatus(OrderStatusMessage  As Channels.Message)

End Interface

At this point you're ready to write the code for these methods, which I'll look at in my next column (the column after that will look at building a client).



SOLVED: "Operation could destabilize the runtime" - ASP.NET 4.5 Hosting

clock October 18, 2012 07:29 by author Administrator

We like to discuss an issue, which normally happens to ASP.NET 4.5 website on Windows Server 2008. We did not spot this issue on Windows Server 2008/Windows Server 2012 and we believe that this issue happens to ASP.NET 4.5 Framework on Windows Server 2008 only. Please note that ASP.NET 4.5 is not supported on Windows Server 2003 or lower.

When you are using Windows Server 2008 and you do make an upgrade of ASP.NET framework to ASP.NET 4.5, your site can stop working with the error message: “Operation could destabilize the runtime

The following is the detail of the error message:

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.  

Exception Details: System.Security.VerificationException: Operation could destabilize the runtime.

To resolve this issue, please kindly make sure the following items are set on your IIS:

1. Please make sure that the ISAPI Filters of your website is set to Revert to Inherited
2. Please make sure that the application pool is running under ASP.NET 4.0 (ASP.NET 4.5 and ASP.NET 4.0 will share the same application pool settings)
3. Please make sure the “Enable 32-bits mode” is set to False

If you are looking to host your
ASP.NET 4.5 website on Windows Server 2012, please have a look at asphostcentral.com

Hope this helps!

VS 2012 Hosting :: ASP.NET Web Forms 4.5 new features in Visual Studio 2012

clock September 25, 2012 08:13 by author Administrator

This post discusses about ASP.NET Web Forms 4.5 features, Web Forms in 4.5 allows you to build dynamic web sites quickly and easily. Web Forms generates much cleaner code on client-side with Unobtrusive Validation in this version. You can also build data-centric applications easily with data-binding features.

If you like to host your ASP.NET Web Forms 4.5, you can have a look at
asphostcentral.com

Typical Web Form which contains more fields and validation controls can generate more code on client-side. When you run this typical form in browser then you can see the page size as below



The reason for this size is because client-side validation is enabled. If you change Unobtrusive validation mode in page load to web forms then you can see the difference.



Now re-compile your application and run the page the result is as shown below, Now page size is much smaller than before



Strongly typed Data Controls

Take a typical Search Form which shows the results in list view. Inside list view you have item template which is having multiple calls to the EVAL expression as shown below



The above method is the standard way of doing data-binding in web forms. You optimize the above using strongly typed data controls.

You can set the Item Type property of List View to the type that you actually data-binding to as shown below



Now you can member variables in place of Eval expressions, member variables are now typed and you will get an Intel license on item class



Model Binding

You may be familiar with Model Binding in ASP.NET MVC, The typical code which you might write in web forms to bind the results in web forms as below



The above code talking to the data base by building a query which does a case insensitive search then it coverts into list binds the results to list view. Let us re-write the above code using Model-Binding



Now there is no page load and click-handler, The above code is not directly interacting with the page. You can populate the formTerm and qsTerm variables using attributes Control and QueryString in model-binding.

The return result of GetResults method is IQueryable. Because the result is of type IQueryable the control has the ability to modify this before it is rendering it to the page. You can use this in sorting and paging. You can specify the same in markup.

Advantage of using Model Binding


As the code is not directly interacting with the page, you can fairly easily unit test the method or even move it to the completely different class.

Support for OpenID in OAuth Logins



The AuthConfig.cs file is standard in all new projects that created in ASP.NET 4.5 in Visual Studio 2012. You can see there are number of external services code is commented out and it is ready to use by putting your custom application credentials.

Now you can use external services to login to the application.

These are the features which you can try out in Visual Studio 2012.



ASP.NET 4.5 Hosting: Filtering using Model Binding in ASP.NET Web Forms

clock September 17, 2012 08:15 by author Administrator

In ASP.NET 4.5, we are provided with the ‘System.Web.ModelBinding’ namespace. This namespace contains value provider classes e.g. ControlAttribute, QueryStringAttribute etc. These classed are inherited from ‘ValueProviderSourceAttribute’. This base class is used to define method parameters to specify source of values for model binding. The means that the parameter passed to the method specifies what value is to be taken for filtering records and what is the source of the value. This source may be Control, QueryString etc.

Step 1: Open Visual Studio 2011 Developer Preview and create a ASP.NET Web Application targeted to .NET 4.5. Name it as ‘ASPNET45_ModelBinding’. To this project, add two new Folders with the name ‘Model’ and ‘Employee’.

Step 2: In the model folder, add a new ADO.NET Entity Framework and  name it as ‘CompanyEDMX.edmx’. This EMD makes use of SQL Server 2008 and a Company Database in it.

The Schema of the Tables in the Company Database is as below:



Department - DeptNo (int) Primary Key, Dname (varchar(50)),Location (varchar(50)).
Employee - EmpNo (int) Primary Key, EmpName (varchar(50)),Salary (int), DeptNo(int) Foreign Key.

After the Wizard completes, the ADO.NET EF model will be as shown below:

Department Employee Table

Step 3: In the Employee folder, add a web form (with master page). Name it as ‘Employees.aspx’. Open the Employee.aspx in Source view and add DropDownList and GridView on it. Set properties of these controls as shown below:



The Entire Page Design markup will be as shown below:



Step 4: Open the Employees.aspx.cs and add the following code in it:

The important part in the code shown above is the ‘GetEmployees()’ method, which accepts a nullable parameter - DeptNo. This is defined using the [Control] attributes. This attribute class defines the constructor which accepts the ID of the control from which the source value is accepted. In the above case, the source control is the DropDownList with ID as ‘ddlDeptName’. Here the ‘GetEmployees()’ method accepts the DeptNo and based upon this value, the related Employees are read from the Employees collection.

Another important portion of the GridView code shown above is that the AllowPaging property is set to true. In the earlier versions of ASP.NET, it was necessary of a Developer to write the code for pagination in similar scenarioes. But in this case, the ‘GetEmployees()’ method returns ‘IQueryable’. Now  when the end-user changes the page-index of the GridView, the query is automatically updated and the next page records are displayed.

Step 5: Run the Employees.aspx and select the Dname from the DropDownList.

Conclusion: Using ASP.NET 4.5 Model Binding Value providers, communication between controls can be made possible by using less code.
