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.
