Timer job reference for SharePoint Server 2016

Summary: Learn about the timer jobs in SharePoint Server 2016.

This article describes the default timer jobs for SharePoint Server 2016. A timer job runs in a specific Windows service for SharePoint Server 2016. Timer jobs perform infrastructure tasks for the Timer service, such as clearing the timer job history and recycling the Timer service. Timer jobs also perform tasks for web applications, such as sending email alerts. A timer job contains a definition of the service to run and specifies how frequently the service is started. The SharePoint Timer service (SPTimerv4) runs timer jobs. Many features in SharePoint Server 2016 rely on timer jobs to run services according to a schedule.

Note

Classic timer jobs are not available in SharePoint Online. The timer jobs in this article are only available on SharePoint Server 2016 and SharePoint 2013.

Manage timer jobs

The SharePoint Central Administration website has a Timer Job Status page on which you can check the status of a timer job and a Job Definitions page on which you can edit the timer job definition. You can find links to these pages in Central Administration, on the Monitoring page, in the Timer Jobs section. You can click Review job definitions to see a list of all timer jobs, or click Check job status to see scheduled and running timer jobs.

On the Timer Job Status page, on the View menu, you can filter the timer jobs at the following levels:

  • All Displays all timer jobs for the farm.

  • Service Displays all the timer jobs for a particular service. If you select this option, use the Service menu to select the service by which you want to filter the listed jobs.

  • Web Application Displays all the timer jobs for a web application. If you select this option, use the Web Application menu to select the web application by which you want to filter the listed jobs.

  • Server Displays all the timer jobs for the specified server. If you select this option, use the Server menu to select the server by which you want to filter the listed jobs.

  • Job Definition Displays all the timer jobs for the specified job definition. On the Timer Job Status page, open the Job Definition menu, and then click Change Job Definition to get a list of job definitions.

  • Failed Jobs Displays all the timer jobs on the farm that failed to finish.

The SharePoint Timer service (SPTimerv4) is based on the Gregorian calendar for scheduling. For every job that you schedule, you specify when the timer job will run, specified in a 24-hour time format. You must specify the time in local time instead of as an offset from Coordinated Universal Time (UTC). The time is stored in that format. By default, daily, weekly, and monthly schedules also include a window of execution. The timer service selects a random time within the window of execution interval to start the job on each applicable server. This capability helps to reduce the overall load of resource-intensive timer jobs that run on multiple servers on the farm. You can specify timer job schedules on the Edit Timer Job page or by using Microsoft PowerShell. For more information, see Use Windows PowerShell cmdlets to manage timer jobs in SharePoint 2016.
