第5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_SIZE NAME TYPE VALUE ------------------- ----------- ------------------ db_cache_size big integer 4194304 (4M) Why is the value set to 4194304 and not to 2516582()
