You have installed two 64G flash devices to support the Database Smart Flash Cache feature on your database server that is running on Oracle Linux. You have set the db_smart_flash_file parameter: DB_FLASH_CACHE_FILE=/dev/f lash_device_1, /dev/f lash_device_2 How should the D3_flash_cache_size be configured to use both devices? 

Answer options:

A. Set DB_FLASH_CACHE_SIZE=64G.B. Set D3_FLASH_CACHE_SIZE=64G, 64G.C. Set D3_FLASK_CACKE_SI2E=i28G.D. db_flash_cache_SI2E is automatically configured by the instance at startup.

B

* Smart Flash Cache concept is not new in Oracle 12C - DB Smart Flash Cache in Oracle 11g. In this release Oracle has made changes related to both initialization parameters used by DB Smart Flash cache. Now you can define many files|devices and its sizes for "Database Smart Flash Cache" area. In previous releases only one file|device could be defined. DB_FLASH_CACHE_FILE = /dev/sda, /dev/sdb, /dev/sdc DB_FLASH_CACHE_SIZE = 32G, 32G, 64G So above settings defines 3 devices which will be in use by "DB Smart Flash Cache" /dev/sdasize 32G /dev/sdbsize 32G /dev/sdcsize 64G New view V$FLASHFILESTATits used to determine the cumulative latency and read counts of each file|device and compute the average latency
