How to set IIS ApplicationPool “Private Memory Limit” value using PowerShell

Question

I'm using PowerShell for auto-deploying website, and recently found AppPool setting which cannot be set with PS. or at least I did not manage to find out how to do it.

$appPool = $serverManager.ApplicationPools.Add($sitename)...

I need to set "Private Memory Limit" to some value, but it looks like there is no such property at ApplicationPool or ApplicationPoolRecycling object.

Does anybode know workaround for this issue?

Answer 1

This script uses Get-Webconfiguration and Set-WebConfiguration to get the value for private memory for all app pools. You can set each individually or set the application pool defaults for them to inherit. I have commented out the line which actually does the set.

import-module webadministration

$applicationPoolsPath = "/system.applicationHost/applicationPools"
$applicationPools = Get-WebConfiguration $applicationPoolsPath

foreach ($appPool in $applicationPools.Collection)
{
    $appPoolPath = "$applicationPoolsPath/add[@name='$($appPool.Name)']"
    Get-WebConfiguration "$appPoolPath/recycling/periodicRestart/@privateMemory" 
    # Set-WebConfiguration "$appPoolPath/recycling/periodicRestart/@privateMemory" -Value 1000
}

I am adding an answer because I was having trouble using the existing.

import-module webadministration
$applicationPools = Get-ChildItem IIS:\AppPools

foreach ($appPool in $applicationPools){
Set-ItemProperty IIS:\AppPools\$appPool.name `
-Name recycling.periodicrestart.privateMemory -Value 7000000
}

Your responses helped me come up with a solution to a problem that I was having with my WSUS servers. I knew that it was the application pool size for the WsusPool that was giving me problems so I made the following PS script and applied it to the root OU for my WSUS servers (I have 3) I was getting a connection error and my option to Reset Server Node didn't help. The event viewer had Event IDs 12002, 12012, 12032, 12022, 12042, 12052, and 12072.

Set-WebConfiguration "/system.applicationHost/applicationPools/add[@name='WsusPool']/recycling/periodicRestart/@privateMemory" -Value 0
