What can Cheryl Watson’s Tuning Letter do for you?

Since January 1991 Cheryl Watson, and since 2014 Frank Kyne, have filled over 8,500 pages with their unique style of practical and impartial z/OS, and MVS tuning and measurement advice. Today over 9000 analysts in fifty countries read Cheryl Watson’s Tuning Letter.

We’ve kept our readers up-to-date with in-depth articles on topics such as Workload Manager, CICS, parallel sysplex, Parmlib members, I/O tuning, how to go about processor upgrades, LPAR management, z/OSMF, software pricing, and capacity planning techniques.  We’ve printed the latest news about new processors, user problems, and important APARs.  We’ve included timely information, such as tips on new manuals, key websites, user Q&As, and our SHARE trip reports.  We even publish a CPU Chart of all the IBM Z processors, showing such data as MIPS by workload and MSUs.  Our readers continue to say we’ve saved them their subscription cost many, many times over.  Every past issue has techniques that are still applicable today.

Tuning for years to come

Cheryl and Frank plan to continue the Tuning Letter for many years to come.  They’ll be covering new and continuing hot topics such as z/OSMF, Zowe, cloud, containers, cost reduction through software and hardware, and ongoing developments in Workload Manager and Parallel Sysplex.  They’ll continue to point out important APARs and other news which will help you do your job better.  But with over thousands of  pages already in print and more to come, it becomes increasingly difficult to research a subject in the printed format.  All that has changed with our new electronic edition.
