Configuring a Task Recovery Strategy

Configuring a Task Recovery Strategy

By default, all tasks use a restart recovery strategy. Verify the task recovery strategy for any Mapping task in a workflow that you enable for recovery.
If the workflow is not enabled for recovery, the Data Integration Service ignores the task recovery strategy.
  1. Open the workflow in the editor.
  2. Select a Mapping task.
  3. In the
    Properties
     view for the task, click the
    Advanced
     tab.
  4. Select one of the following task recovery strategies:
    • Restart task
      . When a task with a restart recovery strategy is interrupted or encounters a recoverable error, the Data Integration Service cancels the task and the workflow. The Data Integration Service restarts the task when the workflow recovers.
      Define a restart strategy for any Mapping task that writes data for a Human task. If you configure a Mapping task with a restart recovery strategy, develop the mapping to support a complete restart of the task.
    • Skip task
      . When a task with a skip recovery strategy encounters a recoverable error or a nonrecoverable error, the Data Integration Service skips the task. The Data Integration Service runs the next stage in the workflow.
  5. Repeat the steps for any other Mapping task in the workflow.
  6. Click
    File
    Save
     to save the workflow.
