Oracle Course Description:
This course teaches the fundamentals of JCL coding, and uses a variety of popular utility programs to illustrate the concepts and also to allow students to practice coding JCL in the workshops. Typical utility programs are used throughout the course to show how JCL is used in different situations. These utilities include: IEBGENER, SORT, IDCAMS, and IEFBR14. Diagnose and correct JCL errors and read the JES JOB LOG.
