The Workflow Engine is a set of Java executables responsible for managing and executing steps in an administrator-defined workflow and keeping track of state information (which is persisted in a database). When the necessary approvals have been given, the Provisioning System provisions the resource as requested.
During the course of workflow execution, the Workflow Engine can send one or more email messages to notify users of changes in the state of the workflow. In addition, it can send email messages to notify users when updates have been made to proxy, delegate, and availability settings.
You can edit an email template in the Designer for Identity Manager or in iManager and then use this template for email notifications. At runtime, the Workflow Engine retrieves the template from the directory and replaces tags with dynamic text suitable for the notification.
Additional details about the Workflow Engine, including how to configure and manage provisioning workflows, are in Section IV, Configuring and Managing Provisioning Workflows.
