Teradata PT automatically restarts a job when an error that allows a retry, such as a database restart or deadlock, occurs before, during, or after loading data. The job will restart on its own without a manual resubmission of the tbuild command.

Jobs will automatically restart as many times as specified at the original job launch with the tbuild -R (not the lowercase -r) option. If -R is not specified in the tbuild command that launches the job, the default limit of up to five restarts will apply.

Automatic restarts will use the last interval checkpoint taken, if interval checkpointing is specified for the job. If not the automatic restart will use the two standard default checkpoints.

While processing a restart, the infrastructure will sleep for the duration of time as specified by the value of -w command line option before proceeding with the new invocation.
