Why should we need to change DMKSYS depending on where we want the nucleus loaded and IPL'd??
?
The whole idea of "alternate nucleus" is to be able to test a new prod nucleus and be able to fall back if it fails.
?
Another important concept is to be able to place exactly the same code in production that was previously tested WITHOUT ANY ALTERATIONS.
?
IF you look at the code updates suggested in Melinda Varian's "What Mother Never Told You..." document, you will see that the idea is to simply separate the IPL volume as being different than the SYSRES volume... the nuc load deck would still be used to load onto the same cuu/cyl as specified in DMKSYS
?
The latest version of "alt nuc" that I implemented in 199x? (HPO, SEPP??) also made the cyl location definable by volid.
?
I think it not ok to have primary and alt nucs needing separate dmksys content
?
