FAST_START_PARALLEL_ROLLBACK

Property Description
Parameter type String
Syntax FAST_START_PARALLEL_ROLLBACK = { HIGH | LOW | FALSE }
Default value LOW
Modifiable ALTER SYSTEM
Basic No

FAST_START_PARALLEL_ROLLBACK specifies the degree of parallelism used when recovering terminated transactions. Terminated transactions are transactions that are active before a system failure. If a system fails when there are uncommitted parallel DML or DDL transactions, then you can speed up transaction recovery during startup by using this parameter.

Values:

If you change the value of this parameter, then transaction recovery will be stopped and restarted with the new implied degree of parallelism.
