Your business-critical COBOL applications may not be running optimally. Getting the best performance requires updating your program modules to target the latest IBM Z® mainframes, however compiler migration and full source recompilation can be a challenging and time-consuming project. IBM® Automatic Binary Optimizer for z/OS® (ABO) uses advanced optimization technology to generate code targeting the latest IBM Z mainframes to improve application performance without the need for recompilation. ABO reduces the CPU usage of your COBOL applications to lower operating costs while maintaining strict compatible functionality of the original modules. The performance achieved by ABO V2.1 is on-par with Enterprise COBOL V6.3. ABO V2.1 uses Execution-based price metric. This means the price of ABO V2.1 is based on the capacity of the LPAR in which the product runs. This provides you the flexibility to grow capacity as needed. ABO V2.1 generates SMF-89 record to help you manage capacity.
