Code: How to Change AppFabric Cache Size on a Host
By default AppFabric will allocate 50% of the RAM on a machine for the cache. If you want to change the available amount of memory for AppFabric cache on a host you'll need to stop the cluster and then run Set-CacheHostConfig
Code: AppFabric Diagnostic Powershell Commands
Below are some powershell commands I found useful in testing AppFabric Cache Clusters. You'll want to import the following modules:
Import-Module DistributedCacheConfiguration Import-Module DistributedCacheAdministration
use-cachecluster
use-cachecluster -Provider "System.Data.SqlClient" -ConnectionString "Data Source=dbmachine\instance;Initial Catalog=DatabaseName;Integrated Security=true"
get-cachestatistics
get-cachestatistics -cachename YourCacheName Size : 212661 ItemCount : 14 RegionCount : 30 RequestCount : 2267 MissCount : 288
get-cacheclusterinfo
get-cacheclusterinfo -Provider "System.Data.SqlClient" -ConnectionString "Data Source=dbmachine\instance;Initial Catalog=DatabaseName;Integrated Security=true"
IsInitialized Size Provider ConnectionString
------------- ---- -------- ----------------
True Small System.Data.SqlClient Data Source=odcsgwinsql11....
