How to remotely stop/start an application pool in IIS 8

Question

Caveat: using one line each!

I had these commands for use in IIS 6, and they worked just fine.

Start:

(get-wmiobject -namespace 'root\MicrosoftIISv2' -computername 'REMOTE_SERVER' -class 'IIsApplicationPool' | where-object {$_.Name -eq 'W3SVC/AppPools/MY_FANCY_APPPOOL'}).InvokeMethod('Stop', $null)"

-and-

Stop:

(get-wmiobject -namespace 'root\MicrosoftIISv2' -computername 'REMOTE_SERVER' -class 'IIsApplicationPool' | where-object {$_.Name -eq 'W3SVC/AppPools/MY_FANCY_APPPOOL'}).InvokeMethod('Start', $null)

I'm looking for an alternative in IIS 8. I need a couple of one-liners and they must be Powershell commands. I'm invoking them via a InvokePowerShellCommand activity in TFS. Is there anyone out there who can help me out?

Answer 1

You can do the following to start your application pool :

Invoke-Command -ComputerName "REMOTE_SERVER" -ScriptBlock { Start-WebAppPool -Name "MY_FANCY_APPPOOL" }

You can do the following to stop your application pool :

Invoke-Command -ComputerName "REMOTE_SERVER" -ScriptBlock { Stop-WebAppPool -Name "MY_FANCY_APPPOOL" }

Answer 2

To start, sometimes you need to add an explicit wait so that the app pool responds to control messages:

Invoke-Command -ComputerName "$REMOTE_SERVER" -ScriptBlock { Import-Module WebAdministration; Start-Sleep -s 10; Start-WebAppPool -Name "$APP_POOL_NAME" }

And to stop:

Invoke-Command -ComputerName "$REMOTE_SERVER" -ScriptBlock { Import-Module WebAdministration; Stop-WebAppPool -Name "$APP_POOL_NAME" }
