This program also allows you to display the subsystem shared memory segment for debugging purposes 这个程序还允许您为调试目的显示子系统共享内存段。
This enables faster communication between db2 partitions at the cost of reduced size of shared memory segment available for other uses such as the database buffer pools 这使db2分区间的通信速度更快且减少的共享内存段大小可以用于其他用途，如数据库缓冲池。
If the application uses shared memory segments , care has to be taken to place the starting addresses of the shared memory segments appropriately unless the user wants to rely on the system - provided initial addresses 如果应用程序使用共享内存段，那么必须要小心地设置共享内存段的起始位置，除非用户想依赖系统所提供的初始地址。
