This course builds on the skills taught in the definitive introductory JCL course - 'z/OS JCL Workshop Part 1 - Foundation Skills'. It teaches the exploitation of the important advanced features and facilities available in z/OS JCL. It also shows how JCL maintenance can be simplified in order to aid productivity.<br>The course is taught through a combination of classroom tuition and practical hands-on exercises.<br><br>This course is also available for one-company, on-site presentations and for live presentation over the Internet, via the Virtual Classroom Environment service.
z/OS JCL Workshop Part 2 - Advanced Functions & Utilities
A good knowledge and understanding of JCL. This can be gained by attending the course z/OS JCL Workshop Part 1 - Foundation Skills.
- code jobs to run on systems other than the local host
- code JCL statements to create PDSE library and data files
- code JCL to create VSAM data sets without IDCAMS
- use the OUTPUT statement more fully
- describe the function of various batch utilities
- code and execute nested procedures
- use the INCLUDE statement to ease JCL maintenance
- use the SET statement to resolve job wide variables
- describe how SET is used by z/OS when commands are issued to invoke jobs
- code and execute SORT.
