Transient journaling supports rollback and backup operations.

To preserve the restore capability of transient journaling, changing only journaling options with ALTER TABLE retains the version number of the table. Other ALTER TABLE options change the structure of tables and thus require incrementing the table version number.

The transient journaling options include:
  • WITH JOURNAL TABLE
  • JOURNAL
  • AFTER JOURNAL
