Hi guys this article explains you about How To Update Conflict Error in SharePoint Using PowerShell Script. Many of you must have come across the issue “An update conflict has occurred and you must re-try this action” and it is suggested to remove the file system cache on the front-end servers. There are many articles to show how to do this manually. But here I will show you how to resolve it using a PowerShell script.
Cause for this issue
This issue occurs if the contents of the file system cache on the front-end servers are newer than the contents of the configuration database.
Resolution
To resolve this issue, clear the file system cache on all servers in the server Farm on which the Windows SharePoint Services Timer service is running. This can be done manually, but consider a large Farm where the administrator needs to login to each of the servers to perform the activity manually. It is time-consuming and people can make mistakes. PowerShell becomes handy here.
The following procedure can resolve the issue:
- Stop the SharePoint timer service
- Take a backup of the system cache files before deleting it
- Delete the XML files from the cache folder
- Reset the cache.ini file to the value 1
- Start the SharePoint timer service
Now I will explain how to perform the preceding tasks using a PowerShell script.
- Stop SharePoint timer service
The following piece of code stops the SharePoint timer service:
Function StopSPTimerServicesInFarm([Microsoft.SharePoint.Administration.SPFarm]$farm)
{
Write-Host ""
foreach($server in $farm.Servers)
{
foreach($instance in $server.ServiceInstances)
{
# If the server has the timer service then stop the service
if($instance.TypeName -eq $timerServiceInstanceName)
{
[string]$serverName = $server.Name
Write-Host "Stop " $timerServiceName " service on server: " $serverName -fore yellow
$service = Get-WmiObject -ComputerName $serverName Win32_Service -Filter "DisplayName='$timerServiceName'"
$serviceInternalName = $service.Name
sc.exe \\$serverName stop $serviceInternalName > $null
# Wait until this service has actually stopped
write-host "Waiting for '$timerServiceName' service on server: " $serverName " to be stopped" -fore yellow
do
{
Start-Sleep 1
Write-Host -foregroundcolor DarkGray -NoNewLine "."
$service = Get-WmiObject -ComputerName $serverName Win32_Service -Filter "DisplayName='$timerServiceName'"
}
while ($service.State -ne "Stopped")
write-host " '$timerServiceName' service on server: " $serverName " stopped successfully" -fore green
break;
}
}
}
Write-Host ""
}
- Backup config cache files
The following piece of code backs up the config cache files before deleting it:
Function BackupSPConfigFiles([Microsoft.SharePoint.Administration.SPFarm]$farm)
{
write-host ""
write-host "Backup SP config cache files" -fore yellow
foreach($server in $farm.servers)
{
foreach($instance in $server.ServiceInstances)
{
if($instance.TypeName -eq $timerServiceInstanceName)
{
$ServerName = $server.name
$FolderName = $servername + "SPConfigCacheBackup"
write-host "Creating a folder to hold the backup files" -fore magenta
write-host "Checking whether the folder aleady exist"
if(Test-path $scriptbase\$FolderName)
{
write-host "Folder already exists and the script is deleting it......"
remove-item $scriptbase\$FolderName -recurse -confirm:$false
write-host "Existing folder deleted" -fore green
}
else
{
write-host "Folder does not exist"
}
New-Item $scriptbase\$FolderName -type directory
write-host "New folder created to hold the backup files" -fore magenta
write-host "Backup of SP config files for the server " $serverName " started ...... " -fore yellow
$path = "\\" + $serverName + "\c$\ProgramData\Microsoft\SharePoint\Config"
Copy-Item $path -Destination $scriptbase\$FolderName -recurse
write-host "SP config cache files backed up for the server " $serverName " Sucessfully..." -fore green
}
}
}
write-host "SP config caches files are backed up" -fore green
write-host ""
}
- Deleting XML files
The following piece of code deletes the XML files:
Function DeletingXMLFiles([Microsoft.SharePoint.Administration.SPFarm]$farm)
{
Write-host ""
write-host "Deleting SP config cache XML files from each server in the farm" -fore yellow
$path = ""
foreach($server in $farm.servers)
{
foreach($instance in $server.ServiceInstances)
{
if($instance.TypeName -eq $timerServiceInstanceName)
{
$serverName = $server.Name
write-host "Deleting SP config cache files from the server " $servername -fore magenta
$path = "\\" + $serverName + "\c$\ProgramData\Microsoft\SharePoint\Config\*-*\*.xml"
remove-item -path $path -force
write-host "SP config cache files deleted on the server " $servername -fore magenta
break
}
}
}
write-host "SP config cache XML files from each server in the farm is deleted successfully......" -fore green
write-host ""
}
- Reset timer cache
The following piece of code resets the timer cache:
Function ResetTimerCache([Microsoft.SharePoint.Administration.SPFarm]$farm)
{
write-host ""
write-host "Reseting the value of timer cache to 1" -fore yellow
$path = ""
foreach($server in $farm.servers)
{
foreach($instance in $server.ServiceInstances)
{
if($instance.TypeName -eq $timerServiceInstanceName)
{
$serverName = $server.Name
write-host "Reseting the value of timer cache file in server " $serverName -fore magenta
$path = "\\" + $serverName + "\c$\ProgramData\Microsoft\SharePoint\Config\*-*\cache.ini"
Set-Content -path $path -Value "1"
write-host "Value of timer cache file in server " $serverName " is resetted to 1" -fore magenta
break
}
}
}
write-host "The value of timer cache is resetted to 1 in all the SP servers in the farm" -fore green
write-host ""
}
- Start SharePoint timer service
Function StartSPTimerServicesInFarm([Microsoft.SharePoint.Administration.SPFarm]$farm)
{
Write-Host ""
foreach($server in $farm.Servers)
{
foreach($instance in $server.ServiceInstances)
{
# If the server has the timer service then stop the service
if($instance.TypeName -eq $timerServiceInstanceName)
{
[string]$serverName = $server.Name
Write-Host "Start " $timerServiceName " service on server: " $serverName -fore yellow
$service = Get-WmiObject -ComputerName $serverName Win32_Service -Filter "DisplayName='$timerServiceName'"
$serviceInternalName = $service.Name
sc.exe \\$serverName start $serviceInternalName > $null
# Wait until this service starts running
write-host "Waiting for " $timerServiceName " service on server: " $serverName " to be started" -fore yellow
do
{
Start-Sleep 1
Write-Host -foregroundcolor DarkGray -NoNewLine "."
$service = Get-WmiObject -ComputerName $serverName Win32_Service -Filter "DisplayName='$timerServiceName'"
}
while ($service.State -ne "Running")
write-host $timerServiceName " service on server: " $serverName " started successfully" -fore green
break;
}
}
}
Write-Host ""
}
