Re: Cumulative PTF package downloaded

Mark--

The image catalogs take the CD swapping and slow reading out of the equation-- the system just has to read, read, read those changes and stuff them where they belong.

As far as the "Side A" and "Side B" that IBM talks about, my sneaking suspicion is that there aren't 2 complete copies of the OS. I think IBM uses the library list to its advantage-- and library "QSYS" is actually "QSYS_SIDE_B" + "QSYS_SIDE_A." All PTFs apply on Side B, running in place of those on Side A. We're always told that we can IPL from "Side A" in case of problems with a PTF... which would just remove the "QSYS_SIDE_B" from the list. Applying a PTF permanently moves the appropriate pieces from the B library to the A library as we've always been told.

Does anyone know if I'm just blowing smoke or not??

I just completed the cume PTF install and it took only 45 minutes! Not
even close to previous installs. It's the first time I did it on a Power 6
box, so I can only attribute part of the time gain to the image catalog
process.
