A reference is an application specific pointer to an object that usually lives in a larger context, such as a server or cluster, and is used by multiple parties.
引用是应用程序的特定指针，该指针指向通常存在于更大的上下文(如服务器或集群)中并且供多方使用的对象。
Because data is replicated across the cluster, each server in the cluster has enough main memory to store the entire context data.
由于数据在整个集群中进行复制，集群中的每个服务器都有足够的主存来存储整个上下文数据。
Or, to put it in the context of the earlier discussion, the cluster is the root container for the resolution of names rather than the queue manager.
或者，放在前面讨论的上下文中来说，集群是用于名称解析而不是队列管理器的根容器。
