Kursbeschreibung

This course is designed to describe the basic components that apply to all z/OS systems. It includes high level concepts that apply to the z/OS hardware platform and the z/OS software. It then provides a more detailed analysis, description and lab activities that can be applied to the system programmer role to maintain z/OS systems. Discussion activities include: The POR, IPL process, JES implementation and operating environment, VTAM environment for TSO, ISPF, SNA and TCP/IP networking, RACF, ISPF/PDF and UNIX System Services. It defines the classic approach to data management in a z/OS system. It identifies various software products and utilities used to define, maintain, and manage catalogs and data sets in the z/OS environment. It also discusses Parmlib usage and requirements for system initialization and operation that include: System symbolics, WLM, SFM, RMF and system logger. Both single system and multi-system sysplex usage is identified. z/OS install, upgrade options, maintenance using SMP/E and I/O configuration requirements using HCD is listed and described. Objective - Describe the basics of z/OS architecture - Identify basic components of a z/OS system - Discuss what you have learned about LPARs - Describe maintenance principles - Identify and list the POR process - Describe the IPL process - Identify the basic address spaces - Describe how to shut down z/OS - Implement a basic JES2 batch environment - Identify how work can be started in z/OS and it's relationship to the job entry subsystem - Describe how JES2 prepares and executes work in z/OS - Explain JES2 start options - Describe JES2 parameters that can be customized to support z/OS batch - Identify how communications and control of JES2 can be done using the operator commands and SDSF - Describe JES3 configuration and job processing phases - Identify JES3 start options - Describe the two networking schemes in the z/OS environment: SNA and IP - Identify SNA networking resources - Explain how SNA sessions are established - Describe the role of TCP/IP as a physical filesystem in UNIX System Services - Implement and start a local VTAM instance to provide the base for SNA applications such as TSO - Implement and start TSO - Start a TCPIP stack and check accompanying messages - Identify the main functions of Security Server (RACF) and the role it plays in controlling user access to the system - Describe the contents of RACF user, group, and resource profiles - Describe how RACF profiles are used to authorize user access to a data set resource - Identify two key members used for TCAS startup - Name the components of ISPF - Describe the general layout of ISPF/PDF panels - Describe how UNIX System Services are used in z/OS - Describe briefly the UNIX Shell and utilities and how they are accessed - Describe the application services provided in UNIX System Services - Describe how security is handled in UNIX System Services - Describe the classical z/OS data management - DASD init: VTOC, VTOC index - ICF catalog creation: BCS, VVDS - MCAT/UCAT - IDCAMS utility - DFSMS: DFSMSdss, DFSMShsm - Data, storage, and management classes - Define the hierarchical data management - HFS file system - zFS file system - Define load-parameters for IPL - Define symbols for use in system initialization - Define a configuration for system initialization - Define a library for procedures - Identify the sysplex resources required to run WLM - List the main components that comprise a WLM service definition for a system/sysplex - Describe the function of WLM service definition parameters such as workloads, service goals, periods, and WLM subsystems - Describe how SMF data set are created and used - Explain SMF record types and how they are used - Identify the three RMF monitor types - Describe how the RMF monitor is used for reporting purposes - Identify System Logger components and usage for: - Sysplex configuration and CF logstreams - Single system and DASD-only logstreams - Describe SMF usage of logstreams - Describe the differences between IOCDS and IODF - Identify and list the HCD definition process sequence - Describe how the HCD dialogs are used to define a configuration - Discuss the purpose of Hardware Configuration Manager - Describe the overall concept of SMP/E: Global, target and DLIB zones - Describe what elements and SYSMODs are - Create an SMP/E working environment - Identify the batch and ISPF interfaces to SMP/E - Install a user function using RECEIVE, APPLY, and ACCEPT - Explain how to remove a SYSMOD with RESTORE - Describe the installation options available to install z/OS - Use the attributes of z/OS elements and features to identify the contents of a z/OS product - Describe the contents of the ServerPac offering and important install documentation sources - List the main steps in the ServerPac build process - Describe hardware and software prerequisites for performing a ServerPac installation in: - The driving system - The target system
