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 also introduces and explains the use of DFSORT ICETOOL, a dataset reporting utility that provides a batch front-end for DFSORT, which is capable of performing complex sorting, copying, merging, reporting and analytical tasks using multiple datasets in a single job. This tool can be called from a program or executed directly in a batch job. ICETOOL provides a set of 'operators' that provides a wide variety of tasks. This course shows how to effectively exploit the benefits offered by this utility.<br><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.
