RE: Perm vs Temp PTF applies

That's the 'link loader' in some other messages. The link loader keeps track of what PTFs you're applying and the order they get applied in. If you're nervous about overloading the loader, you can break up your PTFs into batches-- cume, then groups, then any strays you may have. Apply each batch separately. But I've stuffed a lot into the machine at once, and it takes some doing to fill it up!

AFAIK, the '(Re)spin/Resave level' refers to the version of the OS you find on your distribution media CDs/DVDs. Every now and then IBM says there are so many PTFs we'll just do another save of the complete OS and use that as the distribution media. GREATLY reduces the number of PTFs loaded from the cume. But if you have the latest cume + groups, you'll be caught up just as if you had the latest 'respin.' See the link mentioned previously: http://www-01.ibm.com/support/docview.wss?uid=nas8N1022015

Define "over-stuff the system" please :)

The nice thing about the iSeries is that it knows how to apply PTFs!
Except if you over-stuff the system, it will sort out whatever PTFs you
give it and apply them in the right order. If a mandatory apply *PERM is
required, it will automatically insert a 2nd IPL in the IPL to apply the
PTFs. Like magic!

And don't be afraid if some PTFs are included in more than one PTF group
or the cume + a group. The system 'knows,' and only loads them once.

As far as over-stuffing is concerned- it doesn't seem to mind a Cume
package + group PTFs + a few strays that looked interesting all at once.
