from OS Diagnostic Workshop for Language Environment Applications

This course is a diagnostic workshop designed to enhance z/OS Language Environment application debugging skills. The workshop will provide a detailed description of CEEDUMP, highlighting the various z/OS Language Environment control blocks relevant to application developers. The course will also teach techniques for effectively debugging application problems using LEDATA within IPCS. A refresher on IPCS will be presented, including logic flow and the use of registers. In addition, storage management concepts will be covered, with particular emphasis on diagnosing heap overlays and locating parameters based on the type of link used. The course will use detailed exercises and hands-on labs to illustrate many of the concepts that will be used. Although the workshop is designed with an emphasis on applications written in the C and C++ programming languages, the skills learned are useful for debugging applications written in any of the languages supported by Language Environment.
