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
FALSE
Parallel rollback is disabled
LOW
Limits the maximum degree of parallelism to 2 * CPU_COUNT
HIGH
Limits the maximum degree of parallelism to 4 * CPU_COUNT
If you change the value of this parameter, then transaction recovery will be stopped and restarted with the new implied degree of parallelism.
