WebSphere Compute Grid

IBM first delivered a proprietary Java batch API in the WebSphere Compute Grid product, and the same functionality has been rolled into Websphere Application Server traditional, since Version 8.5. Many of the constructs (including the basic XML-defined job with step artifacts implemented in Java) were adopted in the Java Batch 1.0 specification (JSR 352, led by IBM), the APIs are not backwards compatible, and a migration effort is required to go from the Compute Grid programming model to the JSR 352 standard.

Likewise, many of the operational capabilities including scaling into a multi server WebSphere environment driven via an external scheduler are conceptually similar, but we have made some different design decisions in some areas.

Now that we've gotten past those disclaimers, (intended to avoid confusion), here are some links to the proprietary "Compute Grid" - based Java batch function in WebSphere Application Server traditional.
