In the driver configuration, the Subscriber channel processes only events that pertain to work orders. For many drivers, the Subscriber channel performs changes in the third-party application in response to events in the Identity Vault. However, for the WorkOrder driver, the Publisher channel is the agent that performs the work orders.
Through the Publisher channel, the Identity Manager 3.5.1 WorkOrder driver queries the Identity Vault for work orders. The Publisher channel then configures the work orders in the driver.
For more information on how the Subscriber channel and Publisher channel are configured, see Section 6.8, Configuring the Subscriber and Publisher Channels.
