ES270: z/OS System Operators

מק"ט: #6330 | משך קורס: 24 שעות אק'

To provide an overview of the z Operating System (OS), look at the systems from both a hardware and software prospective, and develop a basic understanding of System z partitioning capabilities, Processor Resource/Systems Manager (PR/SM), z/OS, Job Entry Subsystem 2 (JES2), Job Entry Subsystem 3 (JES3), Time Sharing Option (TSO), TSO Extended (TSO/E), System Display and Search Facility (SDSF), z/OS Communications Server, and System z channel subsystem usage for various channels, such as, Enterprise System Connection (ESCON), Fiber Connector (FICON), and the Open Systems Adapter (OSA). It will also describe the Initial Program Loader (IPL) process and enable you to become comfortable issuing z/OS commands from a Multi Console Support (MCS) system console or extended MCS console.

ES05: An Introduction to the z/OS Environment


  • Review of System z servers and z/OS
  • This unit reviews the basic facts and concepts of the z/Architecture, System z servers, and the z/OS operating system.
  • z/OS MVS commands
  • This unit describes the various z/OS MVS commands can may be used to change and display channel path and I/O device status.
  • JES and TSO
  • This unit briefly introduces the concept of job entry and time sharing. It discusses the basics of JES2, TSO/E, ISPF/PDF, and SDSF.
  • z/OS data sets
  • This unit introduces the z/OS MVS data set types, the system catalog, the DFSMS family of products, and cataloged procedures.
  • z/OS console operation
  • This unit describes the operations console of a z/OS system.
  • z/OS IPL flow
  • This unit describes the steps required to perform a successful initial program load (IPL) of a z/OS system.
  • There are a total of nine lab exercises available. These exercises consist of the following:
  • Two exercises to set up lab access to z/OS MCS console, TSO console, and SDSF. These exercises demonstrate logon, logoff, and disconnect procedures and access to online documentation to look up commands and messages.
  • One exercise using basic z/OS commands to display various system and I/O status.
  • Two exercises to demonstrate how JES2 can be controlled and monitored using JES2 type commands.
  • One exercise using TSO to allocate a data set, code a few lines of job control language (JCL) to submit, and view a simple job.
  • One exercise to identify use and control of the MCS console, change console characteristics, and perform basic console recovery actions.
  • One exercise to perform z/OS shut down, IPL a z/OS system, and issue the appropriate commands to start JES2, VTAM, and other subsystems that might be required.
  • One optional exercise to use z/OS commands to display and modify system or device status.
