The OP is referring to a shop that reinstalls z/OS as a way to get to a current
RSU level. In the years in between releases of z/OS, they reorder everything
at a higher maintenance level and then do a complete reinstall.
Has anyone ever heard of this method for putting on maintenance? Can you
I know of one very large customer with many hundred of LPARs, changed they
way they did maintenance.
If they had MVSA, MVSB,MCSC,MVSD, they created a new LPAR MVSE, with all
the maintenance of all products on it. They added it to the sysplex, and
when it proved to work, they removed(killed)
Maintenance: Asking For a Friend
In a Sysplex environment it is possible to shift the workload off of one system
so that it can be IPLed at any time, not just on weekends.
IMO, customers that are stuck in the old way of doing things should not serve
as a model for others.

Hi Tom,
Can you workload shift running Jobs from one LPAR to another?

Hi Brian,
One of my customers decided (many years ago) to upgrade software/apply
maintenance once a year (on each of their 4 complexes).
There are not enough weekends in the year to do this more frequently
(due to other groups doing upgrades and "blocked out" weekends).

All RSU's are not created equal. The quarterly ones (i.e. 2303 2306 2309
2312), are tested by IBM differently and tend to be "easier" to install.
There is NEVER a good reason to skip maintenance for a long period of time.

There is a shop where the current philosophy is to not put on any maintenance
other than a PTF here and there if it is needed for a problem. But no RSU
maintenance. Instead of maintenance, the plan is to just reinstall z/OS and all
related products anytime they want to refresh the maintenance
