The twbrmcp command removes all checkpoint files associated with userId or jobId.
For information on checkpointing, see the Teradata Parallel Transporter User Guide (B035-2445).
In the event of a job failure, the checkpoint files for the job are retained in the checkpoint directory to support job restart from the last checkpoint taken. If the job needs to restart from the beginning, then the checkpoint file(s) for that job must be removed.
The twbrmcp command specifies which checkpoint files to remove by requiring the use of either the name of the job associated with the checkpoint files or the userId under which the job was executed.
