This parameter specifies the number of processes to be started in a single instance that are reserved for parallel operations.

Setting PARALLEL_MIN_SERVERS balances the startup cost against memory usage. Processes started using PARALLEL_MIN_SERVERS do not exit until the database is shut down. This way, when a query is issued, the processes are likely to be available.
