Upgrade to Oracle Database 12c — Question 27

To enable the Database Smart Flash Cache, you configure the following parameters:
DB_FLASH_CACHE_FILE = /dev/flash_device_1 , /dev/flash_device_2

DB_FLASH_CACHE_SIZE=64G -
What is the result when you start up the database instance?

Answer options

• A. It results in an error because these parameter settings are invalid.
• B. One 64G flash cache file will be used.
• C. Two 64G flash cache files will be used.
• D. Two 32G flash cache files will be used.

Correct answer: A

Explanation

The correct answer is A because the parameters provided are incorrectly configured for the Database Smart Flash Cache. The DB_FLASH_CACHE_FILE parameter specifies two devices, but the DB_FLASH_CACHE_SIZE is set to 64G, which does not match the expected configuration for two separate cache files. Therefore, this results in an error upon startup.
