例如，假设由于测试系统上的内存约束，您无法获得大型的缓冲池，并且希望将大小配置得相同，实际上却不是真正有这么大。
For example, say that you cannot afford to have large buffer pools due to memory constraints on the test system and would like to configure the size the same without actually having them in reality.
当您配置新的缓冲池时，一定要理解它对系统可用内存的影响。
When you configure new buffer pools, make sure that you understand how it impacts the available memory of your system.
因为db2缓冲池是系统主内存的一部分，DB 2数据库管理器在它读取或写入磁盘介质时将它分配给缓存表和索引数据。
Since a DB2 buffer pool is a part of the main memory of the system, the DB2 database manager allocates it for caching tables and index data when it reads or writes to and from media disks.
