z/OS I/O Performance: Do You Have a Problem? ..... October 15th ..... Sign up has ended. Please see Our Presentations page if you would like to download a copy of the presentation slides
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.
The following webinar is presented in conjunction with SHARE
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.
