nonzero value, you will enable which of the following memory-management options?
A. Automatic PGA Memory Management
B. Automatic SGA Memory Management
C. Automatic Shared Memory Management
D. Automatic Memory Management
E. Manual SGA Memory Management

1. 将初始化参数 MEMORY_TARGET 设置为 0。
ALTER SYSTEM SET MEMORY_TARGET = 0;
数据库将根据当前的 SGA 内存分配设置 SGA_TARGET。
2. 将自动设置大小的 SGA 组件的值设置为 0。完成后，重新启动实例。
