Caching mechanism cluster environment

If we use a static hash map for caching process in a normal class (Not a singel开发者_JS百科ton class) will it work in cluster environment?

A static field's value is stored in the memory of the JVM, and each JVM will thus have its own static map. This can be OK, unless you want a unique cache for all the members of the cluster.

Seems like you're writing the requirements for a framework like Terracotta : http://terracotta.org/documentation/product-documentation-1page

You're talking about JVM memory sharing
