The AppFabric Caching Service has not been started.

This server cannot be used by a cache cluster if the Caching Service is not running.

The Caching Service of the AppFabric role service of the Application Server role enables you to implement an in-memory cache platform to store frequently used application data. Each server that runs the Caching Service is referred to as a cache server, and all cache servers that run the Caching Service can be configured as nodes of a cache cluster that is available as a single unified memory cache. Instances of the Caching Service on the cache servers of the cache cluster work together to store and distribute data in the cache.

If the Caching Service on a cache server is not started, that server cannot be a working member of the cache cluster.

Start the Caching Service.

  1. Execute Start-CacheHost to start the Caching Service on the cache host. For more information, see Start-CacheHost (http://go.microsoft.com/fwlink/?LinkId=199820).

  1. If no cache hosts are up in the cache cluster, execute Start-CacheCluster rather than Start-CacheHost. For more information, see Start-CacheCluster (http://go.microsoft.com/fwlink/?LinkId=199822).

  1. After installation for the first time, you will need to start the cache cluster. Configure at least one node in the cluster, and then execute a cmdlet to start the cluster. In the developer scenario (using a single-node cluster), to start a new cluster execute Use-CacheCluster (to set the context of your Windows PowerShell session to a particular cache cluster) and then execute Start-CacheCluster. In a multiple-node cluster, to start all cache host services in the cluster (lead hosts first), execute Start-CacheCluster. For additional cache hosts (and any other cluster-level configuration changes) to be acknowledged by the cache cluster, you need to restart all cache host services with Restart-CacheCluster. To start a specific cache host service, execute Start-CacheHost.
