Abstract: WebSphere Application Server for z/OS supports servers that run in 64-bit mode. It's been that way since Version 6.1.0.4 of the product. 64-bit addressing provides WebSphere with the ability to host very large Java Virtual Machine heaps. But that begs the question: "What's the value of that?" Or, "Why would I consider using such a large JVM heap?"

This paper, written by Frank Golazeski of the IBM WebSphere for z/OS development team, offers some insight into some of the benefits of large memory in WebSphere. The paper is written in an approachable style that offers technical insights and can be understood by the non-programmer.

The paper is 8 pages in length.
