A cold start restarts a CDC task from the beginning of the task without recovery. Cold start enables you to restart a failed CDC task. When you restart a failed task that has recovery enabled, Data Integration does not process recovery data. When you click

Restart

on the job details page, a dialog box appears that enables you to restart the job from the beginning of the task. Select

Restart from beginning of task

and then click

Restart

.

Cold start triggers the creation of new restart recovery tracking files. Any previous CDC processing and restart recovery tracking files are removed. The start point associated with the cold start is associated with the implied position of the

Restart Point

setting on the

CDC Runtime Options

tab of the mapping task.

A warm start resumes processing from the point where the task ended and is the typical way to restart a CDC task after you perform the initial cold start process. Warm start performs recovery when you warm start a task. To warm start a task, you can select

from the mapping task editor, or select

for a mapping task listed in the

page, or select

Restart

for a specific job from the

My Jobs

page. When you click

Restart

on the job details page, a dialog box appears that enables you to restart the job from the point where it last ended. You can configure the

Recovery Strategy

option on the

Runtime Options

tab of the mapping task under
