DB_WRITER_PROCESSES：DB_WRITER_PROCESSES specifies the initial number of database writer processes for an instance. If you use DBWR_IO_SLAVES, only one database writer process will be used, regardless of the setting for DB_WRITER_PROCESSES. Parameter type: integer Parameter class: static Default value: 1 or CPU_COUNT / 8, whichever is greater Range of values: 1-20 DB_WRITERS (As of Version 8.0, this has been renamed DBWR_IO_SLAVES) Number of DBWR processes started. If this parameter is used, set it to the number of disk drives used by the Oracle datafiles. Use of this parameter will result in an increased need for system semaphores and an increase in the processes parameter. Default Value: 1 Dependencies: PROCESSES
