Free up capacity to do more on IBM Z®
Your COBOL applications—backed by the legendary resilience, security, and scalability of IBM Z—are among your enterprise’s most valuable assets. They run mission-critical operations with business logic that is unique to your organization. But when your success demands these applications process ever-increasing workloads, capacity on the general-purpose central processor (CP) may become a scarce resource, limiting your ability to innovate and add new workloads.
Fortunately, you can easily free up the capacity you need to move your business forward by redistributing application workload to the IBM z Integrated Information Processor (zIIP™) with JOPAZ. By compiling COBOL source code into Java bytecode, JOPAZ can shift high-utilization workloads to zIIP specialty engines. This quickly frees up valuable CP capacity, increasing efficiency, improving performance, and creating space for strategic projects—all without changing a line of code.
Run lean. Build big.
Quickly get more value from your IBM Z by efficiently distributing workloads across available processors. By shifting eligible workload to zIIP, JOPAZ unlocks critical CP capacity so you gain breathing room to take on new projects with confidence, while keeping proven systems running exactly as they should—no disruptions, no compromises—just the freedom to innovate on IBM Z.
Create space for growth
High-volume batch processing puts a heavy load on the central processor, impacting performance as it approaches full capacity utilization. With JOPAZ, you can offload processor-intensive jobs to zIIP—instantly freeing capacity for new and latent workloads.


Keep what works
Optimizing your mainframe doesn’t mean putting your business at risk. With JOPAZ, you can keep your trusted COBOL applications as-is and maintain them with the usual development tools. Databases and core systems stay on the IBM Z. No rewrites, no data migrations and no irreversible decisions. Just immediate capacity gains and performance benefits. Evolution, not revolution. On your terms.
Build what’s next
When you reclaim capacity with JOPAZ, you can finally set your sights on building the bold, innovative ideas that will set your business apart. Launch AI initiatives, accelerate digital transformation, implement new applications, and bring your most ambitious projects to life on the secure, reliable IBM Z platform you trust. Innovation shouldn’t start with disruption. With JOPAZ, it doesn’t have to.
