This course contains six discussion units and nine exercises.
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.
- Describe System z usage of z/Architecture
- Identify System z servers and their major components
- Name z/OS functional groups and base elements
- Describe the concept of virtual storage and its exploitation in z/OS
