Overview
This course discusses the use of mainframe data sets and database files to store organizational data and examines the batch and online methods used to process that data. Widely used mainframe programming languages such as COBOL, PL/I, C++, REXX, CLIST and Java are introduced, and a description of the Language Environment used to provide many of these languages with common runtime routines is presented.
Audience
This course is designed for people interested in a career in z/OS application or system programming, that require a broad background on mainframe processing and programming concepts and application.
Prerequisites
Successful completion of Interskill’s IBM (z/OS) – Introduction to the IBM Enterprise Environment course, or equivalent knowledge of mainframe concepts.
Objectives
After completing this course the student will be able to:
- List the attributes of commonly used z/OS data sets
- Describe characteristics of IMS and Db2 databases
- Explain the differences between the CICS, IMS, and IBM MQ transaction systems
- List the features of programming languages that can be used with z/OS
- Describe the purpose of the Language Environment
- Describe the software and the processes used in batch processing
