Scheduling Options

The Scheduling Options dialog enables you to specify which scheduler service you prefer to use on each machine when performing patch scan , asset scan, power state, and patch deployment tasks. The scheduler is used to initiate the tasks at the specified time, whether immediately or at some specified time.



Microsoft Scheduler

Use this scheduler service in those circumstances where it provides the needed functionality.


Shavlik Scheduler

The Shavlik Scheduler service is faster and more secure than the Microsoft Scheduler service. A copy of the Shavlik Scheduler service is pushed to each target machine where it is used to initiate the tasks. With the Shavlik Scheduler service you can specify what should happen to the service after it is finished performing its tasks. The Shavlik Scheduler is required if you wish to use the Scheduled Tasks Manager. You can also install the Shavlik Scheduler to individual machines using the Scheduled Tasks Manager.

The Shavlik Scheduler is the default scheduler service.

Note: If the Shavlik Scheduler should for some reason fail or be unavailable, the Microsoft Scheduler will be automatically invoked (except for power state tasks, which will fail) .


Default Scheduler Port

Specifies the port used by Shavlik Scheduler service. By default the Shavlik Scheduler service listens on TCP port 5120. If desired, you can override this global default on a machine-by-machine basis (see Managing Individual Machine Properties).

Scheduler Lifetime


This specifies what to do with the Shavlik Scheduler service after it completes its tasks on the target machine.

  • Leave the service running: Leaves the service running so it is instantly available for future scans or deployments.

  • Stop the service and leave it installed in service control manager: Stops the service and leaves it installed in service control manager. This doesn't use CPU time on the target machine but it keeps the service available for future use.

  • Stop the service and remove it from service control manager: Stops the service and removes it from service control manager. Certain files are left on the system for easy reuse.
