Course Overview
Identify current and future mainframe trends while gaining a comprehensive understanding of how the hardware, software, and input/output (I/O) interact in a large system mainframe environment. Focus on complex system availability and recovery on the IBM System z9 109 and zSeries servers. Through lecture and hands-on exercises, learn how the hardware and operating systems respond to various recovery scenarios. Complete hands-on lab exercises for each topic discussed during the lecture.
Get an overview of the IBM System z9 109 and zSeries hardware, including the latest servers supporting multiple logical subsystem, greater then 256 channels, spanning channels, new console support and addition Physical Unit (PU) functions. Discuss many mainframe functions, such as logical partitioning mode (LPAR), Central Processor Complex (CPC) activation and initialization, I/O configuration and Hardware Configuration Definition (HCD) in the mainframe environment. Address both Hardware Management Console (HMC) and Support Element (SE) basic and advanced topics, software overview from MVS to z/OS and zSeries architectural enhancements and storage management concepts. Discuss in detail system level recovery concepts for various recovery scenarios. Also, discuss Direct Access Storage Device (DASD) and tape subsystems operational and recovery topics. Explore error recognition along with recovery actions and theory behind those actions with detailed supporting labs demonstrating real-life scenarios
Hands-On Labs
Fifteen labs are included to address HMC Web browser setup, HMC fundamentals, HMC group and system activation, HMC setup, Single Object Operation and advanced functions, Multiple Console Support (MCS) console setup via the 2074 controller, operator system commands, console operations and recovery, dynamic additions of Control Programs (CP) and storage, spin loops and synchronous Write To Operator/Write To Operator with Reply (WTO/WTOR) message processing, disabled loops, restart processing and restartable wait states, identifying and resolving DASD reserve conditions, message interrupt handler and device boxing. There are also four optional labs provided.
