IBM Enterprise COBOL for z/OS Case Study

NTT Data

Introduction

This case study of NTT DATA is based on a December 2017 survey of IBM Enterprise COBOL for z/OS customers by TechValidate, a 3rd-party research service.

Business value driving the upgrade to COBOL V5/V6:
“Machine usage reduction and some ease of use enhancements.”

Challenges

The business challenges that led the profiled company to evaluate and ultimately select IBM Enterprise COBOL for z/OS:

  • COBOL V4 is still in support
  • Sees a increase in volume by 1-20% for COBOL workloads.
  • Would like to see the following categories added or expanded on in future releases:
    • 64-bit support
    • Modernization features
    • Increased performance

Use Case

The key features and functionalities of IBM Enterprise COBOL for z/OS that the surveyed company uses:

  • Compilers/middleware products they are using with their COBOL applications:
    • CICS®
    • DB2®/ Db2®
  • Currently would consider using IBM® Automatic Binary Optimizer (ABO) for z/OS® to reduce migration effort.

Results

The surveyed company achieved the following results with IBM Enterprise COBOL for z/OS:

  • Improved application performance by 6-10% for applications optimized by COBOL V5/V6.

Application Modernization

Some new BIF our application programmers would like much to use.
With BIF it is simpler to understand complex programs rather than write complex procedures to do the same work.
