1. Script to Update the Max Buffer Size of AppFabric Cache
AppFabric Cache has a default max buffer size of 8MB. There are certain scenario where we may need this to modify to satisfy our requirements Find below the script to configure the AppFabric Cache Buffer Size. Script below can be used to increase or decrease this preconfigured size.
#Command Line powershell ./UpdateAppFabricCacheBufferSize.ps1 15000000
#Manual Step before we run any script on Poweshell : Set-ExecutionPolicy Unrestricted
Param([int]$maxBufferSize)
Import-Module DistributedCacheAdministration, DistributedCacheConfiguration
Function UpdateBufferSizeInConfig ([string]$configFilename, [int]$maxBufferSize)
{ $xml = New-Object XML
$xml.Load($configFilename)
$transportProperties = $xml.configuration.dataCache.advancedProperties.transportProperties
if ($transportProperties -eq $NULL)
{ $transportProperties = $xml.CreateElement("transportProperties") }
$transportProperties.SetAttribute("maxBufferSize", "$maxBufferSize") $xml.configuration.dataCache.advancedProperties.appendChild($transportProperties)
$xml.Save($configFilename)
}
$tempConfigLocation = "c:\config.xml"
Use-CacheCluster
Export-CacheClusterConfig -File $tempConfigLocation
UpdateBufferSizeInConfig $tempConfigLocation $maxBufferSize
Stop-CacheCluster
Import-CacheClusterConfig -File $tempConfigLocation -Force
Start-CacheCluster
2. Script to configure the Named Cache and than Add Users in allowed client account list.
#To add a name cahce and windows account to the Cluster.
function CreateNewCache([string]$NewCacheName)
{New-Cache -CacheName $NewCacheName -Secondaries 1 -Force
write-host "Name Cache $NewCacheName is created" -foregroundcolor green
write-host "The cache config info :" -foregroundcolor green
Get-CacheConfig $NewCacheName
}
function AddUser([string]$DomainnameUsername)
{Grant-CacheAllowedClientAccount -Account "$DomainnameUsername"
write-host "$DomainnameUsername is added" -foregroundcolor green
write-host "The list of AllowedClientAccounts below:" -foregroundcolor green
Get-CacheAllowedClientAccounts
}
Write-host "Number of Arguments :" $args.Length;
if($args.Length -gt 1)
{CreateNewCache($args[0])
AddUser($args[1])
}
if($args.Length -eq 1)
{if($args[0] -like "*\*")
{AddUser($args[0])
}
else
{CreateNewCache($args[0])
}
}
Both the scripts provided above are very simple to understand and use through poweshell command line, and used for very specific operation. You can enhance these scripts to even configure advanced settings of Windows AppFabric.
