Hi
I have seen few vendors suggesting an IPL as requisite if you are doing the
product install for first time and If it's upgrade then it's not required.
I am ignorant here. How does this makes a difference ? Why a dynamic update
won't work if it's a first install ?
Programmatically how does it work from zOS perspective.
Apology if this question was already discussed here if so please point me
to the discussion link .

Peter,
If you have one or two LPA modules, or perhaps an LPA dataset that is
standalone and doesn't require any other updates to function, then by
all means, dynamically activate. If, however, you also have STEPLIB or
LINKLIST dependencies, SVC entries, etc., it's much safer to IPL. There
is currently no mechanism to serialize updating both LPA and LINKLIST at
the same time, so if you try to do this with SMP/E maintenance hitting
both, you'll likely fail spectacularly. Good luck.

Tom Conley
