Abstract: Starting with the 220.127.116.11 maintenance level, WebSphere Liberty supports the Java EE7 standard. Part of that standard is JSR-352, the open standard for Java Batch. In addition to supporting the core batch programming model, the IBM implementation in Liberty includes numerous operational extensions. One of those extensions is the ability to involve multiple servers in a single batch environment.
In this paper we'll look at what configuration options influence the nature of the batch server topology. Once we understand our options, we'll consider some different possibilities and why they might be good (or bad) choices for your needs.
