The Teradata Database always restores change images to the AMP that contains the data row, unless the row is from a single after-image journal. If a journal table contains change images for data tables with fallback, the database automatically creates the change images necessary for the offline AMPs when a recovery operation uses the restored journal.

If the journal table contains change images for tables without the fallback option, repeat the journal table restore for any offline AMPs when they return to online status. Any recovery activity using the restored journal must be repeated when the AMPs return to online status.
