  • Mainframe virtualization improves total cost of ownership on IBM z10

    Consolidating and virtualizing applications on the IBM z10 mainframe pays off in a variety of ways. Understanding TCO and ROI mainfrane studies can be improved if the mainframe is viewed as an operational and development platform. It is also helpful to view robustness of the z10 mainframe as less...

  • We have hundreds of BMS map load modules that were last assembled and linked yrs ago

    We have hundreds of BMS map load modules that were last assembled and linked years ago when we still used RMODE(24) and AMODE(24) for everything. We still use these maps every day, but we shifted all of our COBOL code above the line.

  • IBM z10 mainframes and event-driven architectures: Pull the trigger

    The mainframe is becoming better able to support service oriented architectures (SOAs), and therefore EDAs, than ever before. Enterprise driven architecture's (EDA) ability to offer real-time decision support will make it the next "big thing," and IBM z10 mainframers need to act now to implement it.
