Workflow-eventdelivery-throttle: Stsadm property (Office SharePoint Server)

Specifies the number of workflows that can be processed (that is, using the processor, not idle) at the same time across all front-end Web servers.

Throttle is a limit across all workflows; however, batch size is the number of events processed for a single instance, which can have many events queued at the same time. Throttle overrides batch size; that is, if the workflow instance cannot be started or restarted because there are too many instances running across all front-end Web servers, none of the events will be fetched, regardless of the batch size.

stsadm -o setproperty

   -propertyname workflow-eventdelivery-throttle

   -propertyvalue <A valid integer>

   [-url] <http://server_name>

The syntax for the getproperty operation is:

stsadm -o getproperty

   propertyname workflow-eventdelivery-throttle

   [-url] <http://server_name>

Note:
You can substitute -pn for -propertyname and -pv for -propertyvalue.

The following table shows possible values.

Name	Value
propertyname	Gets or sets the name of the property.
propertyvalue	A valid integer. For example, if the value is set to 15, 15 workflows are active in memory, and the sixteenth workflow automatically starts. The auto-start will be sent to the timer service to be processed later. The default value is 15.
url	Typically, a path to the URL of the Web application, in the form http://server_name.

To set the number of workflows to be processed to 20, use the following syntax:

stsadm -o setproperty -pn workflow-eventdelivery-throttle -pv "20"

To view the current setting of the workflow-eventdelivery-throttle property, use the following syntax:

stsadm -o getproperty -pn workflow-eventdelivery-throttle
