IBM Automatic Binary Optimizer for z/OS

COBOL program modules optimization

IBM Automatic Binary Optimizer (ABO) for z/OS improves COBOL program performance without recompiling the source code. It optimizes binary code, preserving program logic and compatibility.

ABO reduces processing time, CPU usage, and operating costs for critical COBOL applications on the IBM Z platform. It complements the IBM Enterprise COBOL compiler, allowing you to optimize both actively maintained and legacy modules for maximum ROI.

Benefits

Optimize performance without recompilation

ABO directly optimizes COBOL modules without the need to recompile the source. Optimized modules have comparable performance as the modules recompiled with Enterprise COBOL 6.

Quick time to value

ABO-optimized modules maintain strict functional compatibility, cutting cycle time and testing effort. Use ABO Assistant to accelerate evaluation and deployment.

Accelerate application modernization

Modernize business-critical applications using ABO to optimize their performance on IBM Z. ABO helps reduce operating costs and maximize hardware ROI with significantly less testing effort.

Advanced program optimization

Optimizes COBOL programs to run on latest IBM Z servers without source code recompilation. The optimized modules that ABO produces will run faster and will have the same behavior as the original COBOL modules.

Testing optimized modules

Using the SCAN option

Comprehensive compiler eligibility

Can optimize CSECTs within program modules that were generated by current supported COBOL compilers as well as legacy compilers as far back as VS COBOL II 1.3.

Eligible COBOL compilers

Using ABO and Enterprise COBOL together

Automated program evaluation and optimization

The ABO Assistant is a suite of tools that accelerate deployment by automating the main steps of profiling, identifying, and optimizing your top CPU consuming COBOL programs. It also reports before and after performance results to ensure that your optimized modules are prepared for deployment.

Using the ABO Assistant

Application performance reporting

The IBM Run Time Instrumentation (RTI) Profiler helps validate optimization results by collecting and reporting on the execution time CPU performance characteristics of your batch z/OS and CICS® applications.

IBM Run Time Instrumentation Profiler overview

IBM DevOps tooling support

Optimized modules are supported by IBM Debug for z/OS, Fault Analyzer for z/OS and Application Performance Analyzer for z/OS which are included in Application Delivery Foundation for z/OS (ADFz).
