Mainframeoptimierung
Improve IBM Z Workload Efficiency Without Recoding COBOL
Erfahren Sie, wie die Neukompilierung von COBOL mit JOPAZ die Mainframe-Modernisierung beschleunigt und IT-Ressourcen für digitale Innovationen freisetzt, ohne den laufenden Betrieb zu beeinträchtigen.
Mainframes lie at the heart of enterprise operations, running mission-critical applications built on decades of proven COBOL business logic. But as business demands grow, application owners face mounting challenges being asked to: support growing workloads, meet tighter Großrechner SLAs, and deliver innovation faster. Meanwhile, COBOL expertise becomes harder to find and the cost of outages remains high. Too often, teams are forced to spend their time maintaining COBOL applications instead of driving innovation.
There’s a better solution: JOPAZ, designed to help your teams meet mainframe SLAs and improve performance without making code changes. Instead, JOPAZ recompiles COBOL into ZIIP auslagern.-eligible Java bytecode. That means IT teams spend less time managing legacy code and more time focusing on innovation.
The problem with traditional approaches to mainframe modernization
Change is inevitable, but many Modernisierung strategies demand time, resources, and changes to business logic, leaving teams scrambling and introducing unwanted risk. In short: Big effort, little gain. Here are some common approaches:
- Move off the mainframe entirely. This requires converting COBOL code into other languages or migrating to cloud environments. While migrations can be done, doing so threatens the underlying business logic that has been running for decades and introduces massive vulnerability.
- Buy bigger mainframes. While adding more processing power is technically easy, it comes with large hardware and licensing costs.
- Manually optimize existing COBOL code. This approach demands significant time and effort while tying up skilled developers who could be working on forward-looking projects.
JOPAZ: A low-risk mainframe optimization solution
The fact of the matter is that you’re going to have to recompile at some point—and if you don’t do it sooner than later, you run the risk of being forced to recompile. By then, your developers won’t have time to test the code anywhere else. Ultimately, this is a threat to the mission-critical workloads you’re trying to protect.
JOPAZ recompiles COBOL into zIIP-eligible Java bytecode to redistribute high-utilization workloads to the zIIP processor. In fact: recompiling just 10% of COBOL programs with JOPAZ can yield a 90% benefit in CPU offload. This small percentage of high-utilization workloads is often what consumes the majority of CPU. Plus, JOPAZ functions as part of your normal development cycle, and you don’t have to move applications into production until they’re operating as expected.
With JOPAZ, you don’t have to choose between modernization and stability. You can increase application speed while freeing up COBOL developers to focus on innovation and do more in less time—all without making code changes or touching mission-critical applications.
Five mainframe optimization benefits of JOPAZ
Here is a closer look at the benefits of JOPAZ for application teams:
Improve mainframe performance to meet SLAs.
Because the underlying business logic remains untouched, your applications maintain stability and reliability throughout the recompiling process. Plus, Auslagerung work to the zIIP processor allows latent workloads to run faster, ensuring that critical jobs finish within their required timeframes.
Enhance mainframe capacity planning and reduce spikes without adding hardware.
JOPAZ flattens CPU consumption spikes. As a result, application owners can:
- Drastically reduce mainframe CPU usage
- Prevent bottlenecks
- Protect mainframe SLAs
- Achieve more accurate consumption forecasting and budget predictability regardless of pricing model (e.g., R4HA or tailor-fit pricing)
- Avoid unexpected, resource-intensive infrastructure upgrades
Reduce the pressure on your COBOL teams.
JOPAZ is minimally invasive and leverages the resources you already have. Same IDEs, same development process, same language—the only differences are the compiler and execution engine. Plus, JOPAZ works with your current development cycle and lets you start with one application, expanding from there. This minimizes disruptions and frees COBOL programmers to focus on innovation instead of addressing capacity issues while recompiling.
Improve database and workload efficiency.
The benefits extend to the database, as well. JOPAZ facilitates the connections between COBOL programs and Db2 databases via Java JDBC technology. This means a significant portion of the database calls also shifts to the zIIP processor, naturally enhancing database performance and reducing general processor strain. In fact, JOPAZ can decrease wall-clock time by as much as 46% by utilizing more efficient zIIP engines.
JOPAZ also supports a more efficient DevOps model around Db2. By reducing performance bottlenecks in database-dependent workloads, teams can move through development, testing, and Bereitstellung with greater confidence and less operational friction.
Extend the longevity of your mainframe.
Because it doesn’t require COBOL and processor upgrades on your mainframe, JOPAZ extends the value of your existing assets—and avoids the risk of failure. By freeing up space on the general processor, you gain mainframe capacity without sacrificing performance.
How to get started with IBM Z workload optimization
Not every Arbeitslast needs to be recompiled (for example: short-running jobs). So, where should you begin? Start small and scale based on the results. We recommend identifying which programs are consuming the most CPU and tackling those first. You might choose to analyze IBM SMF data, or our team can provide the tools to do so. Then, you’ll run them through JOPAZ to confirm the Java Bytecode functions the same way as the original COBOL object code.
Achieving quick wins like this helps your team prove value early, show measurable ROI, and build momentum for your IBM Z workload optimization initiatives.
Optimize mainframe performance with minimal disruption
Your application teams don’t need another risky, time-consuming modernization initiative. They need a practical way to optimize COBOL workloads, reclaim capacity, and reduce operational pressure. With JOPAZ, you can achieve that without rewriting the critical applications your business depends on. That translates to improved performance, protects your SLAs, and most importantly, allows you to reinvest in future innovation.
