function Set-CCMCacheSize { <# .SYNOPSIS Set ConfigMgr cache size from computers via UIResource.UIResourceMgr invoked over CIM .DESCRIPTION This function will allow you to set the configuration manager cache size for multiple computers using Invoke-CIMPowerShell. You can provide an array of computer names, cimsesions, or you can pass them through the pipeline. It will return a hashtable with the computer as key and boolean as value for success .PARAMETER Size Provides the desired cache size in MB .PARAMETER CimSession Provides CimSessions to set CCMCache size on .PARAMETER ComputerName Provides computer names to set CCMCache size on .EXAMPLE C:\PS> Set-CCMCacheSize -Size 20480 Set the cache size to 20480 MB for the local computer .EXAMPLE C:\PS> Set-CCMCacheSize -ComputerName 'Workstation1234','Workstation4321' -Size 10240 Set the cache size to 10240 MB for Workstation1234, and Workstation4321 .NOTES FileName: Set-CCMCacheSize.ps1 Author: Cody Mathis Contact: @CodyMathis123 Created: 2019-11-06 Updated: 2020-01-15 #> [CmdletBinding(SupportsShouldProcess = $true, DefaultParameterSetName = 'ComputerName')] param ( [parameter(Mandatory = $true)] [ValidateRange(1, 99999)] [int]$Size, [Parameter(Mandatory = $false, ValueFromPipelineByPropertyName = $true, ParameterSetName = 'CimSession')] [Microsoft.Management.Infrastructure.CimSession[]]$CimSession, [Parameter(Mandatory = $false, ValueFromPipelineByPropertyName = $true, ParameterSetName = 'ComputerName')] [Alias('Connection', 'PSComputerName', 'PSConnectionName', 'IPAddress', 'ServerName', 'HostName', 'DNSHostName')] [string[]]$ComputerName = $env:ComputerName ) begin { $connectionSplat = @{ } $GetCacheSplat = @{ Namespace = 'root\CCM\SoftMgmtAgent' ClassName = 'CacheConfig' ErrorAction = 'Stop' } $SetCacheSizeScriptBlock = [scriptblock]::Create([string]::Format('(New-Object -ComObject UIResource.UIResourceMgr).GetCacheInfo().TotalSize = {0}', $Size)) $SetCacheSplat = @{ ScriptBlock = $SetCacheSizeScriptBlock } } process { foreach ($Connection in (Get-Variable -Name $PSCmdlet.ParameterSetName -ValueOnly)) { $Computer = switch ($PSCmdlet.ParameterSetName) { 'ComputerName' { Write-Output -InputObject $Connection switch ($Connection -eq $env:ComputerName) { $false { if ($ExistingCimSession = Get-CimSession -ComputerName $Connection -ErrorAction Ignore) { Write-Verbose "Active CimSession found for $Connection - Passing CimSession to CIM cmdlets" $connectionSplat.Remove('ComputerName') $connectionSplat['CimSession'] = $ExistingCimSession } else { Write-Verbose "No active CimSession found for $Connection - falling back to -ComputerName parameter for CIM cmdlets" $connectionSplat.Remove('CimSession') $connectionSplat['ComputerName'] = $Connection } } $true { $connectionSplat.Remove('CimSession') $connectionSplat.Remove('ComputerName') Write-Verbose 'Local computer is being queried - skipping computername, and cimsession parameter' } } } 'CimSession' { Write-Verbose "Active CimSession found for $Connection - Passing CimSession to CIM cmdlets" Write-Output -InputObject $Connection.ComputerName $connectionSplat.Remove('ComputerName') $connectionSplat['CimSession'] = $Connection } } $Return = [System.Collections.Specialized.OrderedDictionary]::new() try { if ($PSCmdlet.ShouldProcess("[ComputerName = '$Computer'] [Size = '$Size']", "Set CCM Cache Size")) { $Cache = Get-CimInstance @GetCacheSplat @connectionSplat if ($Cache -is [object]) { switch ($Cache.Size) { $Size { $Return[$Computer] = $true } default { switch ($Computer -eq $env:ComputerName) { $true { . $SetCacheSizeScriptBlock } $false { Invoke-CIMPowerShell @SetCacheSplat @connectionSplat } } $Cache = Get-CimInstance @GetCacheSplat @connectionSplat if ($Cache -is [Object] -and $Cache.Size -eq $Size) { $Return[$Computer] = $true } else { $Return[$Computer] = $false } } } } Write-Output $Return } } catch { $ErrorMessage = $_.Exception.Message Write-Error $ErrorMessage } } } } |
