Re: Cume, Group

["Larry Bolhuis" <lbolhuis@xxxxxxxxxx>]

IBM Says Cume first then groups.

> From V5R3M5 and forward I ALWAYS Load them all up in one giant image 
catalog and let them fly. For V5R3M0 and previous you need to know how far 
behind you are before you do that or you risk making the link loader go 
'Tilt' and then having to reload the LIC.  (No customer data is harmed in 
this, but downtime ensues.)  You can safely do about 1 years worth of PTFs 
at a time but if you're further back than that you want to do the CUME by 
itself with an IPL and then add other groups. Remember that the HIPER and 
the DB groups are in the CUME. 

Logically it makes sense to do the HIPER first because those are the most 
current. The HIPER will lay down a big bunch of 'Superceded's which will 
mean the CUME and other groups won't have to apply those PTFs only to have 
the HIPER come along and overlay them. However occasionally IBM expects 
that a particular CUME level is already installed before the HIPER is 
installed. Given that, there is the "WHY" for doing the CUME first and 
then the HIPER and other groups.

Subject
Cume, Group






I looked for the "why" in the archives and couldn't find it...

For once and for all I want to understand in my mind which you do first 
and why: cume or group?  I ordered groups and cumes, and I want to know 
which to do first, and what's the reasoning.
