To restart a job from the last checkpoint taken, do the following:
- Determine whether the error that caused the failure is associated with an operator that offers full or limited support of checkpoint restarts.
- Determine the identity and location of the checkpoint file tbuild will use for the restart and whether or not you need to specify a checkpoint interval.
- Run the tbuild restart command.
- Once the job restarts and runs correctly, Teradata PT will delete the checkpoint files automatically.
