oracle官方提到被频繁询问的问题3（缓存融合技术和它的应用）

What is Cache Fusion and how does this affect applications?

Cache Fusion is a new parallel database architecture for

exploiting clustered computers to achieve scalability of

all types of applications. Cache Fusion is a shared cache

architecture that uses high speed low latency

interconnects available today on clustered systems to

maintain database cache coherency. Database blocks are

shipped across the interconnect to the node where access

to the data is needed. This is accomplished transparently

to the application and users of the system. As Cache

Fusion uses at most a 3 point protocol, this means that it

easily scales to clusters with a large numbers of nodes.

什么是缓存融合，它如何影响应用

缓存融合是一种新的并行数据库架构利用集群计算机来实现所有类型的

应用程序的可伸缩性。缓存融合是一个共享缓存架构，它使用高速、

低延迟的内部网络维护集群中数据库缓存的一致性。数据库的数据通过

内部网络运输到集群中需要这些数据的节点上。这个过程对于应用程序

和用户来说是透明的。当缓存融合使用最多的是一个3点协议（ppp协

议？point to point protocl）时，这意味着，它很容易扩展到庞大数

量的其他节点上.
