A specialist is monitoring performance on a server. The data is on another partition within the same array as the OS. The following information is available： （1）The average record written to disk is 16KB （2）The I/O block size is 2KB （3）The stripe size on the RAID array is 16KB Which of the following will improve performance without rebuilding the operating system？（）A、Change the I/O block size to match the RAID Stripe size.B、Change the RAID stripe size to match the I/O block size.C、Change the record size of the database to match the RAID stripe size.D、Change the record size of the database to match the I/O transfer rate.
考题
Your database block size is 4 KB. In this database， you are required to create a tablespace with a block size of 8 KB. Which is the prerequisite for creating this tablespace？（）A、 The parameter DB_CACHE_SIZE must be a multiple of 8.B、 The value of the parameter SGA_MAX_SIZE must be increased.C、 The tablespace must be created with a uniform extent size of 8 KBD、 The parameter DB_8K_CACHE_SIZE must be defined in the parameter file.

多选题You are configuring the PROD database to use an internal tuning algorithm to monitor the performance of the workload. To achieve this configuration， you specify the following parameter settings in the SPFILE:// SGA_TARGET = 512M SHARED_POOL_SIZE = 256M Which two statements are true when modifying the SHARED_POOL_SIZE initialization parameter in the SPFILE？ （）AModifying the SHARED_POOL_SIZE initialization parameter cannot be accomplished if the SGA_TARGET initialization parameter is set to a non-zero value.BModifying the value of the SHARED_POOL_SIZE initialization parameter to zero is not allowed if the SGA_TARGET initialization parameter is set to a nonzero value.CIncreasing the value of the SHARED_POOL_SIZE initialization parameter does not increase the shared pool component size. It sets the lower limit for the size of this component.DDecreasing the value of the SHARED_POOL_SIZE initialization parameter does not reduce the size of the shared pool component immediately. It sets the lower limit for the size of this component.EIncreasing the value of the SHARED_POOL_SIZE initialization parameter immediately increases the shared pool component to the desired size by reallocating the additional memory from the auto-tuned memory components.FDecreasing the value of the SHARED_POOL_SIZE initialization parameter immediately shrinks the shared pool component to the desired size while reallocating the released memory to the memory components that are not auto-tuned.

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_SIZE NAME TYPE VALUE ------------------- ----------- ------------------ db_cache_size big integer 4194304 （4M） 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

多选题You set the value of the SGA_TARGET initialization parameter to 1G to enable Oracle to automatically resize most of the memory components according to the current workload in the database. You issue the following statement： SQL SELECT name， value， isdefault 2 FROM v$parameter 3 WHERE name LIKE ’%size%’； The output of this statement displays that the DB_CACHE_SIZE， SHARED_POOL_SIZE， LARGE_POOL_SIZE， and JAVA_POOL_SIZE initialization parameters contain a zero value. What does this imply？（）AThe SGA_TARGET initialization parameter cannot be set to a value less than 1GBThe SGA_TARGET initialization parameter cannot be set to a value greater than 1GCThe Memory Advisor of the Oracle Enterprise Manager 10g cannot be used to obtain advice on the important memory components of the SGADThe values of the DB_CACHE_SIZE， SHARED_POOL_SIZE， LARGE_POOL_SIZE， and JAVA_POOL_SIZE initialization parameters cannot be set manually.ENo minimum limits are imposed on the DB_CACHE_SIZE， SHARED_POOL_SIZE， LARGE_POOL_SIZE， and JAVA_POOL_SIZE initialization parameters.FThe Automatic Shared Memory Management feature cannot be disabled unless you specify values for the DB_CACHE_SIZE， SHARED_POOL_SIZE， LARGE_POOL_SIZE， and JAVA_POOL_SIZE initialization parameters in the initialization parameter file.
