Specifying CHECKPOINT with the SAVE keyword prepares a journal table for archiving. Teradata ARC writes a checkpoint row to the active journal table. This subtable is then appended to any existing saved table of the named journal. Archive this saved portion by using ARCHIVE JOURNAL TABLES.
The Teradata Database returns an event number that Teradata ARC assigns to the checkpoint entry.
Checkpoint functionality with regards to permanent journals is supported on both Mainframe systems (z/OS) and network-attached systems.
