Your database is configured in shared server mode. However, your senior DBA asks you to modify the value of the PRIVATE_SGA limit in the profile of the users. What could be the reason for this?
A.to limit the User Global Area (UGA) memory allocated to a session from the SGA
B.to limit the amount of memory to be used for the dispatcher queue of a session in SGA
C.to limit the amount of memory to be used for the request pool in System Global Area (SGA)
D.to control the amount of memory allocated in SGA for the local variables for each shared server process
在专用服务器模式下，进程和会话是一对一的关系，UGA 被包含在 PGA 中，
在共享服务器模式下，进程和会话是一对多的关系，UGA 在大池(Large Pool)中分配。
