This scenario covers situations where the workflow has started, but is waiting for a manual action by an approver.
Without Session Persistence
User experience: Transparent failover with respect to the approver provided that the approver has not yet logged in. After the node failure, when the approver does log in, the approver will still see the approval request in his or her inbox, even though the request was triggered from a node that is no longer up.
Recovery steps: No user action is needed.
With Session Persistence
User experience: Same as in the Without Session Persistence mode.
Recovery steps: Same as in the Without Session Persistence mode.
Other Scenario Examples
The workflow is in a sleep state, for example a manual action that sleeps until a sunrise or sunset date for an employee.
An administrator submitted a user creation request that is waiting on an approver to log in and approve the request. The node from which the request was sent failed before the approver approved the request.
