Any change to the structure of a table or join index increments its version number.

You cannot perform any of the following actions over a DDL request that alters table structure.

  • Cluster restore
  • Single AMP restore
  • Rollforward or rollback of a permanent journal

If the ARC utility encounters such a structural table change during a rollforward or rollback operation, then that operation is stopped and an error message is returned in the output listing.
