• E、 Increasing 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.
• F、 Decreasing 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.

• A、It will fail because DB_8K_CACHE_SIZE parameter cannot be changed dynamically
• B、It will be successful only if the memory is available from the auto tuned components
• C、It will fail because an increase in DB_8K_CACHE_SIZE cannot be accommodated within SGA_TARGET
• D、It will fail because an increase in the DB_8K_CACHE_SIZE cannot be accommodated within SGA_MAX_SIZE
