A rollback can affect the performance and availability of resources in Teradata Database while the rollback is in progress. The rollback competes for CPU with other users. Moreover, a rollback can keep locks on affected tables for hours, or even for days, until the rollback is complete. The RollbackPriority field in the DBS Control utility determines the priority given to rollback operations.

For more information on the DBS Control utility, see Utilities.
