I'm trying to be fancy and create an script that other people on my team can use to reset the Config Cache in our SharePoint 2016 farm. This is sometimes necessary if we change anything around our Nintex Workflows or their databases. The settings really like to stick around.

I can get the script to work fine if I have a list of the servers and just use Get-Content and pipe that in to the UNC path where the config files are located. But if I try to keep the script more dynamic and use Get-SPServer, it puts in more information that just the server name.

Here's what I'm trying to run:

$SPServer=Get-SPServer | Where {($_.Role -isnotlike 'Invalid') and ($_.Status -is 'Online')}

Edit: Here's the correct string. Thank you Zack.

$SPServers = Get-SPServer | Where-Object { $_.Role -notlike ‘Invalid’ } | Select-Object -ExpandProperty Address

Then put that into a UNC path to loop through all the servers in the farm:

$selection = read-host

      if ($selection -eq 'TEST')
        {
        Write-Host "TESTING!!!! Clearing the Config Cache on Farm Servers" -ForegroundColor White -BackgroundColor Green
            ForEach ($Server in $SPServer)
              {
                if ( -Not (Test-Path **\\$Server\c$\ProgramData\Microsoft\SharePoint\Config**))
                        {
                        Write-Host "Cannot find folder for "\\$Server\c$\Tools\ClearConfigCache
                        }
                else    {
                        Get-ChildItem -Path \\$Server\c$\ProgramData\Microsoft\SharePoint\Config\*.* -Recurse | Remove-Item -Include '*.xml' -Exclude '*cache*' -Force -Verbose -WhatIf
                        Get-ChildItem -Path \\$Server\c$\ProgramData\Microsoft\SharePoint\Config\*.* -Recurse | Where-Object {$_.Name -eq 'cache.ini'} | Clear-Content -Include 'cache.ini' -Exclude '*.xml' -Force -WhatIf
                        Get-ChildItem -Path \\$Server\c$\ProgramData\Microsoft\SharePoint\Config\*.* -Recurse | Where-Object {$_.Name -eq 'cache.ini'} | Add-Content -Value "1" -Verbose -WhatIf
                        Write-Host "Cache clear and reset complete on" $Server -ForegroundColor White -BackgroundColor Green
                        }
                        {
                        Start-Sleep -Seconds 2
                        }
              }
         }

The Test-Path causes it to fail and returns the path "\SPServer Name=[Whateverserver]\c$\ProgramData\Microsoft\SharePoint\Config

The same variable, though, works fine when I use it to stop the services.

ForEach ($Server in $SPServer)
            {
             $Service=(Get-Service -ComputerName $Server -Name SPTimerV4)
             Start-Service -InputObject $Service -Verbose
             $Service.WaitForStatus('Running','00:00:15')
            }

I don't want to have to use a list for this, there's go to be a way to just input the actual server name for that variable. Below is my full script, in case anyone else has a need for this as well.

Edit: updated the script with the select string from Zack, as well as some changes to the folder filters to not select the Central Admin folder.

Write-Host "                                                                                         

You are here because you need to reset the Config Cache in your SharePoint Farm.         


There are 4 options to choose from.                                                      


You can run a test to make sure the settings in the script are correct and will          
actually do what they're supposed to do and not delete your whole farm.....          
(I highly suggest you do this first)                                                 


You can actually do a Reset, and delete the .xml files that are in the config folders.   


If you forgot something, or something came up, you can Start the timer services back up  
without having to completely exit.                                                   


Or you can always choose to Stop if you are too chicken to pull the trigger.

The Get cmdlet needs the Select-Object at the end to select the property you need.

Instead of:

$SPServer=Get-SPServer | Where-Object {($_.Role -ne 'Invalid') and ($.Status -eq 'Online')}

Use:

$SPServer=Get-SPServer | Where-Object {($_.Role -ne 'Invalid') -and ($_.Status -eq 'Online')} | Select-Object -ExpandProperty Address

The Select at the end finds the given property (in this case Address), and then expands it so you don't end up with an object with just an Address property. Select-Object can be really helpful when you need a property off a set of objects.

  • That worked perfect! I guess I was just brain fried on Friday. Came in today and fixed several other issues in my script above as well. I was trying to do create a text file, get the content, then delete the text file when the script was over, lol. $SPFarmServers = Get-SPServer | Where {($_.Role -notlike 'Invalid') -and ($_.Status -like 'Online')} $SPFarmServers | Select Address | Out-File ".\SPServer.txt" -Force $SPServers = Get-Content .\SPServer.txt – GingaNinja May 8 '17 at 15:19
