03- How to Start & Administer AppFabric Cache

Start and Administer your Memory Cluster from PowerShell

 

After Installation & Setting up Cache, do as below to start using Cache.

 

1.       Go to the Start Menu and type in Caching. You'll have an item called "Caching Administration Windows PowerShell."

2.       Run it as Administrator.

 

 

3.    Type "get-command *cache*" to see all the different commands available for cache management.

4.       To Know all up & running - Type:  Start-Cachecluster

 

HostName : CachePort      Service Name            Service Status Version Info
--------------------      ------------            -------------- ------------
HANSELMAN-W500:22233      AppFabricCachingService UP             1 [1,1][1,1]

 

 

5.       Also Note, Installing Cache add two below library in Visual Studio.

·         Microsoft.ApplicationServer.Caching.Core

·         Microsoft.ApplicationServer.Caching..Client

 

6.       Also Note - Whenever there is a memory upgrade/degrade of RAM on any of the servers where the App fabric cache is installed, by default, the cachesize should be allocated half of the installed physical memory i.e. if the RAM is increased from 2GB to 4GB, the following command should be run

 

Set-Cachehostconfig -hostname <HOSTNAME>  -cacheport 22233 -cachesize 2048

 

7.       To Restart the Cache Cluster - Use the command Restart-CacheCluster

 

8.       After Complete Installation of App Fabric Cache, you can change the startup Type of the ‘AppFabric Caching Service’ from ‘Manual’ to ‘Automatic’ from Services.msc. This will ensure that the caching service will restart after server restart

 

 

Chopping  Cache Memory:

 

App Fabric beauty lies due to its "Memory Chopping' capabilities. I.e.  Memory caches can be chopped off into logical buckets (partitions) and a memory cluster can serve more than one application, if you wanted.

This can be done in the web.config or from code (however you like).

 

Here's a code example helper method where the sample does this manually.

This data could come from wherever you like, you just need to tell it a machine to talk to and the port number. It'll automatically connect to the Caches can also be partitioned.

 

using Microsoft.ApplicationServer.Caching;

using System.Collections.Generic;

 

public class CacheUtil

{

  private static DataCacheFactory _factory = null;

  private static DataCache _cache = null;

 

  public static DataCache GetCache()

  {

      if (_cache != null)

          return _cache;

 

      //Define Array for 1 Cache Host

      List<DataCacheServerEndpoint> servers = new List<DataCacheServerEndpoint>(1);

 

      //Specify Cache Host Details

      //  Parameter 1 = host name

      //  Parameter 2 = cache port number

      servers.Add(new DataCacheServerEndpoint("mymachine", 22233));

 

      //Create cache configuration

      DataCacheFactoryConfiguration configuration = new DataCacheFactoryConfiguration();

      

      //Set the cache host(s)

      configuration.Servers = servers;

      

      //Set default properties for local cache (local cache disabled)

      configuration.LocalCacheProperties = new DataCacheLocalCacheProperties();

 

      //Disable tracing to avoid informational/verbose messages on the web page

      DataCacheClientLogManager.ChangeLogLevel(System.Diagnostics.TraceLevel.Off);

 

      //Pass configuration settings to cacheFactory constructor

      _factory = new DataCacheFactory(configuration);

 

      //Get reference to named cache called "default"

      _cache = _factory.GetCache("default");

                 

                  // Create Region

                  string region1 = "shoppingcart";

                  string region2 = "productcatalog";

                 

                  _cache.CreateRegion(region1);

                  _cache.CreateRegion(region2);       

      

    return _cache;

  }

}
