Problem summary

  • ****************************************************************
    * USERS AFFECTED: Users of IBM Automatic Binary Optimizer      *
    *                 (ABO) for z/OS, v2.1                         *
    ****************************************************************
    * PROBLEM DESCRIPTION: For some large input modules, ABO       *
    *                      consumes a significant amount of CPU    *
    *                      time and memory to optimize the         *
    *                      modules. This APAR adds improvements    *
    *                      to reduce CPU time consumption and      *
    *                      memory use by ABO while optimizing      *
    *                      these modules. Modules that contain a   *
    *                      large number of PERFORM statements are  *
    *                      most likely to show reduced CPU time    *
    *                      and memory consumption during ABO       *
    *                      optimization.                           *
    ****************************************************************
    * RECOMMENDATION: Apply provided service                       *
    ****************************************************************
    ABO was changed to reduce memory usage and CPU time consumption
    when optimizing some larger input modules.
