Public Properties

  Name Description
Public property BatchSelectionSize Attention: Do not change the value of this property without guidance from a support representative. Doing so might adversely affect system performance.

The maximum number of batches that are selected by the import agent dispatcher from the database in a single database round trip.

Public property DispatcherEnabled A boolean value that controls the run enabled status of the dispatcher. When true, the dispatcher runs. When false, the dispatcher does not run.

For the ICFSImportAgentConfiguration interface, when the value of this property is true, the dispatcher runs, but the importer as a whole might still not process import requests when the import agent sub-component has not also been enabled. For more information, see the IsImportAgentEnabled property on the ICFSSiteSettings interface. For a discussion of the importer sub-components, see the ICFSImportAgentConfiguration interface.

Public property DispatcherWaitInterval Attention: Do not change the value of this property without guidance from a support representative. Doing so might adversely affect system performance.

An interval, in seconds, between processing runs for the dispatcher; during this time, the dispatcher remains idle and waits for incoming work. The value specified by this property can represent differing wait intervals depending on the class on which the property occurs, as follows:

  • Except as noted below, represents a minimum wait interval, with a maximum wait interval defined by the LeaseDuration property.
  • For the ICFSImportAgentConfiguration interface, represents a maximum wait interval. (The minimum interval is always 1 second and cannot be changed).
  • For the IAsyncProcessingConfiguration interface, represents a fixed wait interval. (In effect, represents both the minimum and the maximum wait interval).

The interaction between the minimum and maximum intervals occurs in this manner: if in the previous processing run the dispatcher had work to perform, the duration of the subsequent wait interval that the dispatcher actually remains idle is the minimum interval; otherwise, if the dispatcher had no work to perform, the duration is the shorter of these two intervals: (a) Double the previous wait interval or (b) the maximum wait interval. As an example, assuming the minimum interval to be 35 seconds and the maximum as 120, the dispatcher remains idle for 35 seconds, detects no available work, remains idle for 70 seconds (double the previous wait interval), detects no available work, remains idle for 120 seconds (the maximum interval), detects no available work, remains idle for 120 seconds, detects incoming work and processes the work, remains idle for 35 seconds, and so on. Note that, when the minimal interval equals the maximum interval (as is always the case for the IAsyncProcessingConfiguration interface), this example can be simplified. If both the minimum and maximum interval is 35 seconds, the dispatcher remains idle for 35 seconds, detects no available work, remains idle for 35 seconds, detects incoming work and processes the work, remains idle for 35 seconds, and so on.

For the ICFSImportAgentConfiguration interface, this property, despite the name, applies to the importer sub-component known as the import agent and not to the import dispatcher; for information on the importer sub-components, see the ICFSImportAgentConfiguration interface.

Public property LeaseDuration Attention: Do not change the value of this property without guidance from a support representative. Doing so might adversely affect system performance.

The maximum interval, in seconds, allowed a worker to process a batch before the assignment of the batch to another worker. This interval ensures that any abnormal termination of the worker previously assigned to the batch does not prevent batch completion.

Public property MaxInMemoryItems Attention: Do not change the value of this property without guidance from a support representative. Doing so might adversely affect system performance.

This value, in combination with the MaxWorkerThreads parameter, establishes a threshold that, when exceeded, prevents additional batches of federation requests from being inserted in the in-memory pre-fetch queue. The number of items in the queue is reduced as batches of work are dispatched to worker threads. The number of batches in the queue will eventually fall below the threshold and the addition of new batches from the database queue will be resumed.

Public property MaxWorkerThreads The maximum number of import workers that the import agent is allowed to create. Setting the value of this property appropriately prevents the under- or over-utilization of the Content Engine server on behalf of the CFS importer.

For information on the CFS import agent, see the ICFSImportAgentConfiguration interface.
