DB_FLASH_CACHE_SIZE specifies the size of the Database Smart Flash Cache (flash cache). This parameter may only be specified at instance startup. You can dynamically change this parameter to 0 (disabling the flash cache) after the database is started. You can re-enable flash cache by setting this parameter to the original value when the database was started. Dynamic resizing of DB_FLASH_CACHE_SIZE or re-enabling flash cache to a different size is not supported.

This initialization parameter is available starting with Oracle Database 11g Release 2 (11.2.0.2).
