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？ （）

单项选择题You are upgrading to the Oracle 10g Database and will use the Automatic Shared Memory Management feature of the Oracle 10g Database. Which background process serves as the SGA memory broker that  coordinates the sizing of the memory components？（）

A. MMAN
B. PMON
C. MMON
D. MMNL

多项选择题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？（）

A. The SGA_TARGET initialization parameter cannot be set to a value less than 1G
B. The SGA_TARGET initialization parameter cannot be set to a value greater than 1G
C. The Memory Advisor of the Oracle Enterprise Manager 10g cannot be used to obtain advice on the important memory components of the SGA
D. The values of the DB_CACHE_SIZE， SHARED_POOL_SIZE， LARGE_POOL_SIZE， and JAVA_POOL_SIZE initialization parameters cannot be set manually.
E. No minimum limits are imposed on the DB_CACHE_SIZE， SHARED_POOL_SIZE， LARGE_POOL_SIZE， and  JAVA_POOL_SIZE initialization parameters.
F. The 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.

单项选择题Your SPFILE contains the following parameter settings：   SGA_TARGET = 8G   DB_CACHE_SIZE = 4G   SHARED_POOL_SIZE = 2G   LARGE_POOL_SIZE = 512M   JAVA_POOL_SIZE = 512M   LOG_BUFFER = 100M   SGA_MAX_SIZE = 10G   You query the V$SGA_DYNAMIC_COMPONENTS dynamic performance view and discover that the large pool component is currently sized at 1G. You want the value of the SGA_TARGET initialization parameter to 10G， but instead of specifying a value of 10G for the SGA_TARGET initialization parameter， you erroneously execute the following statement：   SQL>ALTER SYSTEM SET SGA_TARGET = 0 SCOPE = BOTH；   What is the result of this statement？（）

A. The database crashes.
B. The large pool releases 512M of memory.
C. The large pool retains 1G of allocated memory.
D. The large pool increases to 1，512M of memory.

单项选择题You create an Oracle 10g database and configure the SPFILE as follows：   SGA_TARGET=2G   DB_CACHE_SIZE=512M  LOG_BUFFER=50M   DB_KEEP_CACHE_SIZE=128M   You modify the SGA_TARGET initialization parameter using the following statement：   SQL>ALTER SYSTEM SET SGA_TARGET = 1G SCOPE = BOTH；   Which entity does this statement affect？（）

A. only the auto-tuned memory components
B. only the memory components that are not auto-tuned
C. both the auto-tuned memory components and the non-auto-tuned memory components
D. neither the auto-tuned memory components nor the non-auto-tuned memory components

单项选择题The SPFILE for your database contains the following parameter settings：   SGA_TARGET = 1000M   DB_CACHE_SIZE = 512M   SHARED_POOL_SIZE = 128M   LOG_BUFFER = 10M   DB_8K_CACHE_SIZE = 50M   What is the total memory that can be distributed across the auto-tuned memory components？（）

A. 940M
B. 990M
C. 690M
D. 1000M
