This course teaches you the operation and recovery of the z/OS system and hardware recovery at the operations level.
It describes and explains mainframe concepts relating to processor components, channel subsystem, operating systems, and zArchitecture storage concepts. It identifies and explains z/OS console usage, operator commands, initial program load (IPL) activities, and compares ESCON, FICON, and zHPF command structure.
This course enables you to acquire the skills necessary to navigate the Hardware Management Console (HMC) to perform daily tasks and advance usage tasks on the HMC and support element to perform problem analysis and other monitoring functions. The focus is on the tree user interface in the lecture and lab materials.
This course also teaches you how to use MVS commands to identify, determine and manage various system resources, such as console usage, CPs, CHPIDs, and I/O resources.
The course explains system level recovery options for enabled, disabled, and excessive spin loops, hot I/Os, missing interrupts, start pending, DASD reserves and boxed I/O conditions, enabled and disabled wait states, and PSW restart actions. It identifies why these actions occur, how the system can automatically resolve them, and if they are not resolved, what potential operator recovery actions can be used.
In addition, the course identifies the IPL sequence describing the various phases during a z/OS IPL. It describes how ESCON, FICON, and System z High Performance FICON (zHPF) channel programs operate. It identifies the command structure using channel command words (CCWs) and transport command words (TCWs) and compares the differences between ESCON, FICON and, zHPF channel operations.
The emphasis is on using the knowledge on how the system interacts with its various components, HMC, consoles, and other system resources to quickly identify and resolve system level recovery problems as described in this course.
This course is for operations personnel and tech support staff who are directly involved in the operation and system support of the z/OS System z environment.
