Setting this variable to on provides a more proactive approach to page cleaning than the default approach (based on CHNGPGS_THRESH and LSN gap triggers).

通过将这个变量设置成on，可以为页清除提供一种比缺省方法(基于CHNGPGS_THRESH和LSN间隙触发器)更积极的方法。

The anomaly detection algorithms of the large scale network(LSN) were required to analysis the vast network traffic of G bit level in real-time and on-the-fly.

随着网络规模和速度的增加，大规模网络异常发现要求检测算法能够在无保留状态或者少保留状态下对G比特级的海量网络业务量数据进行实时在线分析。
