Identify Top CPU Consuming COBOL Programs

White Papers


Abstract

This document is for IBM Enterprise COBOL for z/OS and IBM Automatic Binary Optimizer (ABO) for z/OS clients to help identify their top CPU consuming COBOL programs. By targeting the most performance critical sections of your application code for optimization and migration, you can obtain most of the performance improvements of the latest optimizer and compiler technologies but with a much smaller effort.

Migrating to the latest version of IBM Enterprise COBOL for z/OS or optimizing existing COBOL modules with IBM Automatic Binary Optimizer for z/OS (ABO) is an effective way to reduce CPU consumption, lower operating costs and shorten batch windows. Your applications might contain thousands of program modules; therefore, it is advantageous to target top CPU contributing modules for migration or optimization first. This document provides a step-by-step guide to help identify top CPU consuming COBOL modules in your applications.
