Understanding SMF 98 Address Space Consumption Measurements ..... September 17th ..... Sign up using this link

As we have previously discussed, the SMF 98 records are still a fairly new record, and there is still so much to learn about these high-frequency measurements. One set of measurements provided in the SMF 98 record are address space consumption measurements, which contain information about work unit dispatch times, dispatch counts, execution efficiency, and spin lock data for various priority buckets. What does all this mean? Well, we are not too sure yet, so attend this webinar with Scott Chapman to hear the results of our exploration of these measurements.

z/OS Performance Management in an AI World ..... October 1st ..... Sign up using this link

In an Artificial Intelligence (AI) world, many believe that z/OS Performance Management will change dramatically since the AI engines will help companies manage the performance of their environments. While AI will change the day-to-day z/OS performance management tasks, Actual Intelligence will be more necessary than ever. During this webinar, Peter Enrico will discuss growing need for Actual Intelligence while managing z/OS performance in an Artificial Intelligence (AI) world.

z/OS I/O Performance: Do You Have a Problem? ..... October 15th ..... Sign up using this link

Today, I/O is blazingly fast, at least compared to when we were waiting for platters to spin. And we have zHyperLink that can make disk I/O perform like coupling facility requests. So, nobody has an I/O problem anymore. Right? Well that depends. You may think your I/O response times are fine, but there may be I/Os that are not. Conversely, in many cases, I/O doesn't really impact application performance. In this session, Scott Chapman will explain his frustrations with I/O measurements and explore the surprising (and somewhat obscure) evidence of poor I/O performance.

How Busy is That Mainframe, Really? ..... November 18th ..... Sign up using this link

It’s 9:03 AM, do you know how busy your mainframe is? No points for know how busy it was on average for the 15 minutes starting at 9:00! Your 15-minute performance intervals may be sufficient for many use cases but are likely insufficient for discovering and diagnosing performance problems that last for just a few minutes or less. In this session, Scott Chapman will discuss the SMF 98 and 99 data that lets you see CPU usage on a sub-minute basis as well as the practical utilization of such data.
