Optimize COBOL performance without recompilation, source code migration or performance tuning
COBOL program modules optimization
IBM Automatic Binary Optimizer for z/OS® (ABO) improves COBOL performance without recompiling the source code. It optimizes binary code to reduce CPU usage, cut costs and speed processing, preserving logic and compatibility across both legacy and active modules on IBM Z®.
Features
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.
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.
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.
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.
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).

Technical details
Optimized modules run on z/OS 2.3 and later operating systems.
Optimized modules run on all models of IBM z14®, IBM z15®, IBM z16™ and IBM z17™ servers.
See supported z/OS versions for using RTI profiled in batch or in CICS.
