单选题You have executed this command to change the size of the database buffer cache： SQL ALTER SYSTEM SET DB_CACHE_SIZE=2516582； System altered. To verify the change in size， you executed this command：SQL SHOW PARAMETER DB_CACHE_SIZENAME TYPE VALUE ------------------- ----------- ------------------ db_cache_size big integer 4194304 Why is the value set to 4194304 and not to 2516582（）A
Because 4194304 is the granule sizeB
Because 4194304 is the standard block sizeC
Because 4194304 is the largest nonstandard block size defined in the databaseD
Because 4194304 is the total size of data already available in the database buffer cache

单选题The SPFILE for the PROD database specifies the following initialization parameter values： SGA_TARGET = 2G DB_8K_CACHE_SIZE = 128M You create a tablespace named HR with the non-standard block size of 8K. Four database users are running queries on a table in the HR tablespace. These users complain that the queries are taking longer than usual to complete. While investigating the reasons for this delay， you discover that the database encounters extensive cache misses on the database buffer cache with the block size of 8K. You issue the following statement to increase the value of the DB_8K_CACHE_SIZE initialization parameter to 256M： SQLALTER SYSTEM SET DB_8K_CACHE_SIZE=256M SCOPE = BOTH； What is the result of this statement？（）A
The statement fails because you cannot set the memory components manually if the SGA_TARGET initialization parameter is set to a nonzero value.B
The statement fails because the DB_8K_CACHE_SIZE initialization parameter is not a dynamic parameter.C
The statement increases the value of the DB_8K_CACHE_SIZE initialization parameter to 256M and extracts an additional 128M of memory from the automatically sized memory components.D
The statement increases the value of the DB_8K_CACHE_SIZE initialization parameter to 256M and reallocates an additional 128M memory from the memory components that are not auto-tuned.
