Technical Deep Dive: Running COBOL Batch as zIIP-Eligible Java Bytecode on z/OS 

Moving COBOL batch processing to specialty engines reduces mainframe general-purpose processor usage, but how does it function under the hood? 

Join us for a hands-on technical session exploring JOPAZ, a solution that compiles and executes existing COBOL batch applications as zIIP-eligible Java workloads on z/OS, without altering source code or refactoring applications. 

We will walk through the complete execution path from COBOL-to-Java bytecode translation to runtime execution. You will see how JOPAZ preserves application behavior, manages database access, and integrates seamlessly with your existing JCL, scheduling systems, and operational controls.

For over 55 years, Software AG (a Software GmbH brand) has served as a pioneer in software innovation, earning the trust of the world’s leading brands and governments. While technology evolves, our mission stays the same: helping organizations solve critical business challenges and meet the demands of the future by building on what works. 

Proven Stability for Mission-Critical Demands

Global enterprises depend on Software AG for applications that simply cannot fail. Our Adabas & Natural development platform serves as the backbone for modern systems, optimized to meet the most demanding operational SLAs. We provide the advantage of an unfailing foundation coupled with exceptional transaction speed, availability, and scalability at a manageable cost, ensuring that today’s core systems remain the high-performance engines of tomorrow.

Legacy Systems, Made Modern

Software AG believes that modernization shouldn’t equal disruption. Our modernize-in-place solution JOPAZ offers a risk-free path to mainframe efficiency. By compiling COBOL workloads into Java bytecode, JOPAZ redistributes high-utilization workloads to zIIP, reducing COBOL batch workloads running on the General Processor by up to 80%. No code rewrites, no migrations, no business risk – just a smarter way to optimize what already works. Keep the unmatched performance, security, and reliability of your IBM Z® while creating space for growth.

Future-Ready Data

Today’s AI and modern analytics platforms require a high-performance bridge between legacy systems and the most innovative applications. CONNX provides a singular data integration solution that connects over 150+ sources, delivering your critical data anywhere it’s needed, fast. Whether that’s streaming data into Kafka, powering event-driven applications, or enabling natural-language database queries, we make your enterprise data AI-ready, always accessible, and secure.

Software AG is proud to partner with GSE in our mission to retain the performance, security, and reliability you’ve built over decades, while preparing your systems for the next generation of growth.
