Configure workflow failover

Active workflows are persisted when they are idle, and a timer in the workflow host reactivates the workflow at next due date. The timer resides on the web server with the most recent workflow activity.

Workflow failover is controlled by two parameters in the Process settings in WorkZone Configurator.

  1. Open WorkZone Configurator.
  2. In WorkZone Configurator, click Process > Process settings.
  3. Under Workflow host, specify the WatchInterval and WatchDelay parameters.
Parameter Description

 WatchInterval

Controls intervals between checks. If a web server is unavailable, workflows are not reactivated. In order to avoid this, all workflow hosts periodically check for workflows which are overdue.

Enter a value between 5 minutes and 24 hours (1440 minutes). The default value is 5 minutes.

This parameter applies to all service workflows.

WatchDelay

Controls the amount of time passed since the workflow should have been started.

Enter value between 30 minutes and 24 hours (1440 minutes). The default value is 30 minutes.

The duration of the delay depends on the nature of the workflows. In some cases it is acceptable to have a delay of several hours, whereas in other cases only a shorter period is acceptable. The delay period should, however, be longer than the usual time required to reboot the server.
