To perform an install/backout or a promote/demote, ChangeMan ZMF uses a set of data sets for executing all required jobs. Understanding the members (JCL decks) involved in those data sets, and the flow between these members/jobs is crucial (a prereq) for being able to perform activities such as:
- restarting failed install jobs, for which you should definitely consider to Add restart instructions in Xnode jobs also.
- investigating why something that ChangeMan ZMF is assumed to be doing (like installing a change package in production ...) is actually NOT happening (and it doesn't appear to be obvious to find out what's wrong or missing).
- applying special customizations to these jobs.
