SharePoint: All about one-time timer jobs

Issue:

--------------

They are trying to remove the Faulty search service application "Search service Application AB"

Used below command to delete the SSA

$app=Get-SPServiceApplication | ? {$_.displayname –eq “search service application_AB"}
$app.delete()

$spapp = Get-SPServiceApplication -Name "Search Service Application_AB"

Remove-SPServiceApplication $spapp -RemoveData

Ran PowerShell script to check the history and entries:https://blogs.technet.microsoft.com/spjr/2017/08/16/sharepoint-all-about-one-time-timer-jobs/
