z/OS & JES2 Operations [1041]

Essential knowledge for all operations personnel, this two-day course provides a view of z/OS (with JES2 as the job entry subsystem) through the eyes of the operator and the operator console.
It goes through the system's functions by following a sequence which begins with the start-up of the system (IML and IPL) and then follows how the system controls the application workload coming through and exiting the system. Importantly, the operator's ability to control this process is examined and explained in detail.

REXX is a powerful multi-purpose and user-friendly programming tool used to exploit many IBM and third-party operational products. It is the tool of choice in most (if not all) of today’s larger data centers for those who need to implement new operational procedures both quickly and effectively. This three-day course is designed for TSO/ISPF users who wish to learn how to create and use programs in the REXX language.

This hands-on course describes and explains the access method concepts in MVS and the structure and design of VSAM files. It teaches how to create VSAM files using the utility Access Method Services (AMS), both from a functional as well as a performance point of view. Additionally, it provides the Systems Programmer and Operational Analyst with information on the structure of ICF catalogs and the related VTOC and Index VTOC. Online exercises provide experience in creating, accessing and managing VSAM files. Attendees will create and use clusters, alternate indexes and paths.
