Excellent! >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. Please tell us for purposes do they want to learn and understand? Only non-classified info of course. >I'd especially like to see something that describes components in terms of new >hardware capabilities and how MVS has evolved: About evolve, IBM has webpages about their systems and hardware over the years. >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]) What will you and your team members do if they know it? Do they want to do programming or what? Oh, you forgot one important z/OS part - Security and SAF (and RACF) - That alone (plus APF and SVC) is an interesting study material which will keep you entertained for many years. And there is also PR/SM, Workload management, dynamic address translations, background of IPL and many more other terms and concepts. And z/OS has fantastic diagnostic things.... lots of it. BTW, even as an Assembler programmer like me, don't know ALL of those details fully, but details can be found in IBM Library centre. Book 'Principle of Operation' is one of the nice jewels to be studied. >I'd appreciate pointers to any materials you deem relevant. Why not ask IBM or Steve Comstock who is also here on IBM-MAIN themselves? They provide courses too. Of course some Wikipedia articles are available, but authors and source references are not always available. Tell us for what you want all these info, and you may get lots of help in IBM-MAIN.
