Db2 for z/OS - TSO, JCL & z/OS: The Mainframe Basics

This instructor led, virtual tutorial teaches IBM z/OS personnel the fundamentals in using and working in a z/OS environment. The essentials of the z/OS environment, JCL, ISPF/PDF, TSO Commands, Job submission, and product navigation are the major topics.

Duration: Two day, Instructor led, Virtual Class.

Audience: Personnel using the IBM z/OS environment in the performance of their duties. This course is primarily directed toward application developers and individuals in a technical support role.

Prerequisites: Students should have basic key- boarding skills and have some basic computer concepts.

Workshops: z/OS platform will be used to run class exercises coded by the students.

Course Objectives: After completion of this course, the student will be able to describe the basic z/OS architecture, how to navigate and use TSO menus and basic utilities, use ISPF/PDF commands and editor, understand the purpose of JCL in z/OS, understand types of data sets, code JCL for submitting jobs, execution, and compiling programs.
