IMPROVEMENTS TO ABO'S MEMORY USE

Problem summary
**************************************************************** * USERS AFFECTED: Users of the IBM Automatic Binary Optimizer * * (ABO) for z/OS with large input programs. * **************************************************************** * PROBLEM DESCRIPTION: ABO uses advanced optimization * * techniques to speedup COBOL binaries, * * without requiring re-compilation from * * source. ABO does this by analyzing * * the entire CSECT as a whole, to prove * * the safety and efficacy of each of the * * many hundreds (sometimes thousands) of * * transformation it does. This can mean * * keeping large amounts of data in * * memory, especially for larger input * * programs. This often results in ABO * * consuming virtual memory that is * * larger than what would be considered * * typical for an application. * **************************************************************** * RECOMMENDATION: Apply the provided PTF. * * * **************************************************************** ABO was improved so as to use less virtual memory. In some instances, customers may see as much as 40% reduction in memory use for some programs.
Problem conclusion
ABO now uses less virtual memory.
