Here's complete guidance to the new OS/390 edition of MVS Performance Management (including MVS/ESA Version 5) from an internationally recognized expert. IBM's MVS mainframe operating system underwent a revolution as it grew through Version 5 to become OS/390. OS/390 incorporates many new elements that give MVS new life as a giant server in the client/server equation. If you're a programmer who's tackling performance management of the new MVS, this single guide is the one to rely on, as it addresses all the MVS performance and tuning issues you now face. When you read it, you'll understand why the author is regarded as a leading authority on MVS-and why his workshops for performance analysts are always sold out. Steve Samson details the objects, controls, and problems involved in ensuring that your workloads perform well in a finely tuned MVS system. Using clear explanations, illustrations, and real-world examples, he leads you through the revolution in MVS hardware and software since 1993, including: Parallel sysplex and CMOS processors; The transformation of MVS to an "open" system; Open Edition extensions and UNIX brand certification; Client/server role and enhancements; Consolidation and simplification in OS/390; Workload Manager; In addition, Samson covers: The resources and workloads of MVS; The relationship of MVS to client/server computing; Workload Manager goal mode; The solution of performance problems; Application performance management... and offers appendixes that cover the SRM in compatibility mode. This book can be used with every version of MVS, beginning with SP 4.2.
