Restarting a Checkpoint Operation - TARA/ABU

When CHECKPOINT writes rows to a journal, the transient journal also keeps a record of these rows. Consequently, if the client or Teradata ARC fails, the results of the checkpoint operation are rolled back by the transient journal.

If a Teradata ARC statement specified checkpoints on multiple journal tables, Teradata ARC rolls back only the checkpoint being taken at the time of the client or utility failure.

If CHECKPOINT terminates abnormally, all locks placed by Teradata ARC are removed.

When Teradata ARC restarts, the CHECKPOINT statement completes.
