Mass recall migrated data sets

Sometimes you need to recall a (huge number of) libraries, which fit a certain DSN pattern.

You're lucky if these DSNs (by accident) are just any of these:


Replace IEBCOPY by SERCOPY where possible

A lot of ChangeMan ZMF submitted jobs like promote, demote, install, backout, etc. typically suffer, occasionally, these kinds of IEBCOPY related issues:


Check availability of all CMN/ZMF started tasks

Periodically, typically at the beginning of business hours, you should do an (automatic) verification that all your started tasks are "up", and this across all Z/OS images where at least 1 ChangeMan ZMF STC runs.

A variation of this is verifying that each of these STCs have been started with the correct options (to avoid other problems such at package installation time), to mention a few:

  • The jobname of the STC.
  • The type of ChangeMan ZMF subsystem (D-, P-, DP- or ALL-site).
  • The name of the (remote) site that the STC corresponds to.
  • ...


ASR Runtime Environment for Z-Reports

Creating new ChangeMan ZMF reports, and or customizing any of the reports delivered with ChangeMan ZMF has always been a challenge. Mostly because it requires expertise in the REXX programming language and you need to have 'some' experience in using ChangeMan ZMF's (green) XML services. On top of that, ChangeMan ZMF does not come with any out-of-the-box charts (only reports).

Therefor, in most ChangeMan ZMF implementations, all such reporting (and charting) requests from any type of , gets routed to the (usually overbooked) ChangeMan ZMF administrators who might either not have the required REXX and/or XML experience, or don't really like to do such reporting work. Not to forget the effort that may be required when upgrading to a new ChangeMan ZMF release ...


Z-Apps On Demand

AbitMORE SCM Commander - mascotteAbout

Z-Apps On Demand is about creating a customized version of any of the Z-Apps, so that it perfectly fits the requirements. Developing (on demand) a brand new set of components that fit into the Z-Apps category (and where they will be added to also) is a variation of it.


Using ChangeMan ZMF - Getting started

Introduction to functions and uses of ChangeMan ZMF, which is the foundation (and pre-req) for additional ChangeMan ZMF training classes, to provide general knowledge about major ChangeMan ZMF func

  • General concepts and facilities, including:
    • ChangeMan ZMF's Change Packages.
    • The ChangeMan ZMF Lifecycle.
    • The ChangeMan ZMF Library Structure.
    • The ChangeMan ZMF Architecture.
  • ChangeMan ZMF terminology.
  • Navigating the various ISPF panels in ChangeMan ZMF (Primary menu options and Build menu options).
Duration (hours): 

Using the STUB panel in CMN/ZMF

Document the usages of ChangeMan ZMF's STUB panel, which will be shown it you type primary command S on ChangeMan ZMF's primary option menu (and you've been authorized to use it).


Non-BAS packages not moving anymore

Change packages follow a life cycle, starting from the creation of it, up to the installation of it into production (and optionally followed by a backout it needed). That's the theory, and also what happens most of the time.

However consider some change package that was created by some ChangeMan ZMF user, whereas such package is not yet installed in production (not BAS yet). What happens with such package if the ChangeMan ZMF user quits the company (variation: moves on to another job within the company)?


Packages that remain in DEV for years / forever

Each change package is assumed to be installed in production (and change its status to INS/BAS) some day. The date entered during package creation is the actual planned install date. But with package update (U7) you can change it again, typically to shift the date to some other (later) date. The idea of that is that it allows you to change your initially planned date (during package create) to somewhere later on. Because while the package content is being developed, it turns out that the date that was originally scheduled is too early. So far no problem ...


XML Training for ChangeMan ZMF

Dr Chgman's Training about XML services in ChangeMan ZMFChangeMan ZMF 5.3.x (available since 2003) was the first release delivered with a very rich set of functions that allows you to perform many (though not all) tasks in ChangeMan ZMF without using ChangeMan ZMF's ISPF client (to communicate with the ChangeMan ZMF server, aka the CMN started task). This set of functions is commonly referred to as "ChangeMan ZMF's XML services" (for short: the "XML services").
