Benefits
Using IBM® Automatic Binary Optimizer for z/OS® (ABO) to optimize your COBOL applications lowers your IBM zSystem operating costs. The ABO-optimized modules behave the same as the original modules but consume fewer CPU resources and have shorter processing time.
Using ABO offers the quickest time to value. ABO 2.2 delivers comparable performance benefits to the latest Enterprise COBOL 6 compiler. ABO directly optimizes already-compiled modules and testing cost is significantly reduced. Using the ABO Assistant, an evaluation is simplified, and deployment is accelerated.
Using ABO allows you to maximize the return on investment (ROI) of your new IBM zSystems. IBM Z® server delivers performance with hardware features and advanced optimization technology. COBOL applications compiled by earlier COBOL compilers do not utilize new hardware instructions available on the latest IBM zSystems. Optimizing these earlier COBOL applications with ABO provides delivers up to a 25-year jump forward in the evolution of hardware technology, with access to over 600 new hardware instructions that are already on the IBM z16™, z15®, and z14 systems.
ABO and Enterprise COBOL are designed to work together. Use Enterprise COBOL to compile programs that are under active development; and ABO to optimize programs that are not frequently compiled.
Starting with this release, ABO can now optimize modules from the latest Enterprise COBOL compilers. This enables COBOL developers to use the best set of compiler options during development, debug and test for the fastest application delivery. ABO can then be used for the best production performance with significantly reduced build complexity and testing cost.
