Free Up Capacity for COBOL Applications

Are your COBOL applications straining your mainframe’s capacity?

Your COBOL applications have reliably powered the most critical operations of your enterprise for decades. Unique to your business, they are among your most valuable assets. Today, your success demands these applications process ever-increasing workloads. As batch processing consumes more General Processor resources, you may have less room for new and growing workloads. What if you could reclaim the capacity to support what’s next?

What can you do with 80% batch COBOL CPU savings?

移行の甘い言葉に惑わされないでください

When processing demands push your General Processor (GP) to capacity limits, you have less room for growth. Migration projects may promise relief, but moving mission-critical data or rewriting applications poses unpredictable timelines and unacceptable risks. Fortunately, there is a smarter way to reclaim mainframe capacity and create space for growth without jeopardizing business continuity.

Take the smart path: Redistribute workloads efficiently

Smarter workload optimization makes this possible. By redistributing your COBOL workload across your mainframe’s available processing resources, you immediately reclaim valuable GP capacity for new and growing workloads and system resilience improvements. It’s a straightforward way to optimize the resources you rely on today while ensuring your infrastructure supports what comes next.

JOPAZの仕組み

COBOL を Javaにコンパイル

JOPAZ compiles the source code of high-utilization COBOL workloads into Java bytecode at runtime, making them eligible to run on zIIP.

Redistribute workload to zIIP

JOPAZ then redistributes the Java-compiled COBOL workloads to Java Virtual Machines (JVMs) running on IBM zIIP, freeing capacity on the General Processor. No code rewrites, code conversion, or developer retraining needed.

Access data sources

Maintain reliable access to Db2®, Adabas, VSAM files and sequential files on z/OS with optimized runtime support. Dynamic and static SQL access to Db2 continues seamlessly, while JOPAZ JDBC connectivity can allow you to redistribute up to 60% of Db2 workload to zIIP for compounded capacity optimization.

Optimize performance for JCL and batch integrations

JOPAZの最適化されたランタイムはDFSORTおよびSyncsortに対応しており、既存のJCLワークフローをそのまま維持できます。外部の3GLやアセンブラのルーチンもシームレスに統合でき、既存のバッチ処理環境と完全な機能互換性を確保します。

お好みのツールで開発・デバッグ

JOPAZ leaves your COBOL source code untouched. You can continue to use traditional COBOL development tools or modernize the developer experience with other Eclipse-based environments. Adopt DevOps practices with a distributed version control system like Git. JOPAZ supports all these options.

IBM Zでビジネス継続性を確保

Keep the IBM Z performance, security, and reliability your business depends on while dramatically reducing COBOL batch workloads running on the general processor by over 80%. With JOPAZ, you can avoid the risks of rip & replace and keep your business running without disruption.
