Parallel Sysplex: Synchronizing In-Memory Data
Keeping in-memory data consistent across multiple LPARs introduces coordination challenges. This design separates local reads from Sysplex-wide updates, using native z/OS services to synchronize changes. Synchronizing In-Memory Data Across a Parallel Sysplex Parallel...
Closing the Gap: Advancing Cost Transparency to Strengthen the Z Platform’s Value
This article was previously published on SHARE’d Intelligence.Derek Powe is on the SHARE Board of Directors.The IBM Z platform continues to deliver unmatched reliability, scalability, and transaction efficiency for mission-critical workloads. As organizations...
IBM Bob and VSAM Tuning: Where AI Helps—and Where It Doesn’t
IBM Bob can uncover access patterns and support new mainframer learning. Here’s why every tuning recommendation still needs a reality check. No, this is not the thousandth article about how IBM Bob can convert code from one language to another. What interests me much...
5 Mainframe Performance Tuning Examples That Deliver Quantifiable Value
Mainframe performance tuning does not always require a bigger budget, and lower resource consumption does not always produce a smaller bill. The real opportunity for optimizing mainframe business value lies in understanding where tuning creates usable capacity,...
ROI, Business Case, and Tuning for Value: Round Two
This month at Planet Mainframe Trivia, we've been exploring how organizations maximize the value of their mainframe investments. Creating value doesn't end once a project is approved. Organizations continually look for ways to improve performance, optimize resources,...
The bill for technical debt just came due
“It still runs" no longer means "it’s still safe." Here is why AI-driven exploit discovery is turning decades of unpatched technical debt, legacy frameworks, and hidden API flaws into an immediate target list.This topic has been nagging at me for months, because it...
Stop Defending Mainframe Costs. Start Demonstrating Mainframe Business Value.
Every budget cycle, IBM Z teams are asked to justify the platform's cost. The strongest answer isn't about hardware or software. It’s about measurable business value.Come budget season, and somewhere, a technology leader is asked a familiar question: "Why does the...
The General Ledger, the Mainframe, and the Programmer Who’s Taking Up Golf
Why Finance and Mainframe Teams Need to Stop Talking About Cost Savings and Start Talking About Business ValueThere is an old accounting joke: An accountant is someone who solves a problem you didn't know you had in a way you don't understand. For decades, many...
