Classification: UNCLASSIFIED Caveats: NONE Hello List,
We have a couple of team members wanting to learn more about MVS internals. They already understand quite a bit of usage (e.g. SMP/E, PARMLIB, TSO and JCL) but are interested in soldifying their understanding of operating system fundamentals. I'm attempting to assemble an "information roadmap" and find very little that introduces the operating system with a fairly narrow scope at a reasonably introductory level. There are books that describe bits and pieces of it, ad-nauseum, but I find little that paints all of these pieces together into a bigger picture. Some sources that I have found include "Introduction to the new Mainframe: z/OS Basics" and some volumes in the "ABCs of System Programming" series. They do a fair job of providing a technical overview of the various storage managements and IOS. I'd especially like to see something that describes components in terms of new hardware capabilities and how MVS has evolved: 1) The original dispatcher (especially RBs and interrupt management), task management (especially the difference between DUs), program management (especially the PSW and what APF means), storage management and I/O management 2) Serialization techniques over the years (WAIT/POST, ENQ/DEQ, Locks, Latches) 3) Additions to the dispatcher (SRM and WLM) 4) Storage evolution (24bit-to-31bit in XA, ARs and data spaces in ESA, 31bit-to-64bit in z/OS) 5) Centralized (shared) programming support (e.g. SVCs, subsystems, PCs) 6) Availability improvements (e.g. GRS, sysplex [XCF] and parallel sysplex [XES]) I'd appreciate pointers to any materials you deem relevant. Thanks, Alan Classification: UNCLASSIFIED Caveats: NONE ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
