Past Performance Tips from Our Experts
John Baker – “Since a catalog cannot span volumes or exceed 123 extents, it is important to at least allow it to grow beyond the old 4G limit by defining it as Extended Format and Extended Addressability. If you haven’t done these things (EF/EA), it would be a good idea to do so before it trips you up.”
Todd Havekost – “Processor cache operates far more effectively at lower utilization levels. In my specific experience, operating at percent utilizations in the 30’s instead of the upper 80’s reduced MSU consumption by 30% (13,000 MIPS!)”
Brett Allison – “Compressing data may be a good way to gain back capacity, but there can be hidden performance problems if compressible workloads are not first identified. Visualizing these workloads is key to determining when and where to successfully use compression… Otherwise, you may be trading a capacity issue for a performance problem.”

Is Some Automation Unnecessary Noise or Just Lower Priority Work?
Computers are great at doing what we tell them. They don’t get tired, bored, or complain about the endless work we have them doing. But sometimes automation is running in not so obvious places. Learn some practical guidance for managing those workloads.

z/OS Anomaly Detection allows analysts to automatically detect workload and application changes, saving them countless hours of manual labor and intensive scrutiny while trying to determine the significance of changes
Avoid Islands In Your Data Lakes
Executives have been asking for a holistic view of the enterprise applications and infrastructure for years. The result has been a slew of overly complex, hard to maintain, expensive, and siloed IT management solutions.
