對於企業在維護SharePoint farm server時候，會根據需要考慮是否在每個web frond end server上enable Timer service instance去執行timer job，還是disable。
那麼如何check當前的server上是否啓用了Timer service instance呢？ 可以通過下面方法查看。
方法一：
1. 打開SharePoint Central Admin-> Monitoring-> Review Job Definitions;
2. 在顯示的Job definition右邊設置filter查看當前server是否有job；
3. 如果當前server沒有job definition，則timer service instance在此server是disable的。
方法二：
通過下面script執行查看。
Add-PSSnapin Microsoft.SharePoint.PowerShell
$farm = Get-SPFarm
$disabledTimers = $farm.TimerService.Instances | where {$_.Status -ne "Online"}
if ($disabledTimers -ne $null)
{
foreach ($timer in $disabledTimers)
{
Write-Host "Timer service instance on server " $timer.Server.Name " is not Online. Current status:" $timer.Status
Write-Host "Attempting to set the status of the service instance to online"
$timer.Status = [Microsoft.SharePoint.Administration.SPObjectStatus]::Online
$timer.Update()
}
}
else
{
Write-Host "All Timer Service Instances in the farm are online! No problems found"
}
如果當前server沒有開啓，會顯示下面信息。
