Why do Java on z/OS?
•Focus development skillset around Java
As Java skills become more prevalent and fewer “classic compiled language” (eg. COBOL, PL/I, etc.),
the motivation is to focus development effort around a common programming skill.
•Reuse business logic between platforms, OLTP and batch
To create a more singular design and code stream, share skills across different classes of workloads,
and to streamline the build / test / deploy process.
•Java has excellent performance on IBM z Systems
Steady advances over the past 10 years have produced tremendous results..
•Leverage the specialty processors on IBM z Systems
Java processing can be offloaded to the zIIP, lowering the overall cost profile of running batch
processing on the mainframe. In a word: cost.
•Give yourself maximum platform flexibility
Things change. Sometimes the reason for choosing a platform change; using Java gives you the best
flexibility to take advantage of the right platform at the right time for your application.
Important: this does not mean wholesale replacement of existing function that
serves the business needs. Business imperatives drive technical solutions. 4
