About this Course

Code TPZL1_BZ301
Duration 4 Days

This course is a diagnostic workshop designed to enhance your z/OS Language Environment application debugging skills. The workshop will present a detailed walkthrough of a CEEDUMP highlighting the different z/OS Language Environment control blocks relevant to application programmers. This course will also teach techniques to effectively debug application problems using LEDATA under IPCS. An IPCS refresher will be presented, including logic flow and register usage. In addition, storage management concepts will be covered with an emphasis on diagnosing heap overlays and locating parameters depending on the type of linkage used. The course will utilize detailed exercises and hands-on labs to illustrate many of the concepts that will be used. Although the workshop was developed with a focus on application written in the C and C programming language, the skills gained are useful for debugging applications written in any of the languages supported by Language Environment.
