Expert z/OS performance and cost reduction advice

We’re thrilled to announce that on September 1, 2024, Planet Mainframe became the new publishers of Cheryl Watson’s Tuning Letter. There subscribers will find future Tuning Letter issues as well as all the past issues, and everyone can subscribe to and read the Cheryl’s List blog and see all the contents of our previous public pages. We couldn’t have found a better steward to advance the goals of our Tuning Letter: to provide both entry-level and in-depth articles for the z/OS systems staff to help increase mainframe efficiency and lower costs. Please see the blog post here.

Tom and I want to thank you for your support and friendship since our start in 1987. At 80 (me) and 82 (Tom), we think it’s time to work on our bucket list. The photo is us on a sailboat in Spain this year. But we’ll still continue to provide advice to the management and staff at Planet Mainframe.

So long, and thanks for all the fish!    (From Hitchhiker’s Guide to the Galaxy)
