Microsoft AppFabric 1.1

Agenda

In-memory caching DB caching Page output caching 2010

◦ Windows Server AppFabric 1.0 Microsoft AppFabric 1.1 for windows server

Background of caching

AppFabric can be installed on the following operating systems:

Windows Server 2012 Windows Server 2008 R2 Windows Server 2008 Service Pack 2

AppFabric can be installed for development and testing on the following operating systems:

Windows 8 Windows 7 Windows Vista Service Pack 2

Supported Env:

Supported Architectures: 32-bit (x86) 64-bit (x64)

◦ Hardware requirements: Minimum Hard Disk Space: 2GB Computer with an Intel Pentium-compatible CPU that

is 1 GHz or faster for single processors; 900 MHz or faster for dual processors; or 700 MHz or faster for quad processors.

Hardware Requirements

All features of AppFabric require a .NET Framework:

Microsoft .NET Framework 4 and optionally requires Microsoft .NET Framework 3.5 Service Pack 1

Internet Information Services (IIS) 7 Internet Information Services (IIS) 7 Hotfix #980423

IIS Web Deployment tool Windows PowerShell 2.0 (final version) (this

is not required for users on Windows 7,Windows Server 2008 R2, or later)

To target the correct version of the .NET Framework◦ Open your Visual Studio .NET project.◦ In Solution Explorer, right-click the project name

and then select Properties.◦ Select the Application tab of the Project

Properties dialog.◦ Verify that the target framework version is .NET

Framework 2.0 or higher.◦ In Visual Studio 2008, uncheck the Client-only

Framework subset checkbox. In Visual Studio 2010, select .NET Framework versions that do not specify "Client Profile".

Prepare Dev Env

Install AppFabric Client on dev machine. To add references to the AppFabric caching

assemblies◦ Open your Visual Studio .NET project.◦ In Solution Explorer, right-click the project name and

then select Add Reference.◦ Select the Browse tab of the Add Reference dialog.◦ Navigate to the .\Windows\System32\AppFabric directory.◦ On 64-bit systems, the AppFabric directory will not be

directly visible. To work around this problem, create a new folder with the name “SysNative” and copy AppFabric folder to this folder. This results in navigating to the C:\Windows\SysNative\AppFabric directory in this step.

Prepare Dev Env

Add a reference to the following two assemblies: ◦ Microsoft.ApplicationServer.Caching.Client.dll◦ Microsoft.ApplicationServer.Caching.Core.dll.

Application In Our Case

Does not restart auto after reboot. Work around.

◦ Set the AppFabric Caching Service's Startup type to be Automatic

◦ Another option is to schedule a startup task to execute the Use-CacheCluster and Start-CacheHost commands.

Auto Restart

For development and testing environments, ◦ with licenses for Windows Vista (SP2 or later) and

Windows 7 at no additional cost. For production environments,

◦ with licenses for Windows Server 2008 (SP2 or later) and Windows Server 2008 R2 at no additional cost.

In production environments, ◦ only active directory domain joined machines. ◦ The high availability caching feature in Windows Server

AppFabric is available only on Windows Server 2008/R2 Enterprise Edition.

There are no client access licenses for Windows Server AppFabric.

Effective cache host responsibilities

false false SQL Server or a custom provider performs the cluster management role. This is not a lead host.

Normal cache host operations only.

false true SQL Server performs the cluster management role. This is a lead host if you change the leadHostManagementsetting to true.

Normal cache host operations only.

true false Lead hosts perform the cluster management role, but this is not a lead host.

Normal cache host operations only.

true true Lead hosts perform the cluster management role. This is a lead host.

Normal cache host operations and works with other lead hosts to manage the cluster.
