You USE the Oracle initialization parameter fast_start_mttr_target to specify the number of seconds you want the crash recovery to take. Oracle will try to recover the

instance as close as possible to the time that you specify for the fast_start_mttr_target parameter. The maximum VALUE of this parameter is 3600 seconds (1 hour).

During instance recovery, in the first roll forward operation, the database server MUST apply all TRANSACTIONS between the last checkpoint and the end of the redo log to the datafiles. Thus, in order to tune instance recovery, you control the gap between the checkpoint position and the end of the redo log. This is called Mean Time to Recover (MTTR).
