- With a lot of difficulty.
- What I do is use the SMIT panel "Copy Software to Hard Disk for Future
- Installation", to copy anything off a PTF tape into a temporary
- directory. Then I run a script that simply deletes all those PTFs that
- I already have on the installation server, keeping only the new ones
- and copying them to my permanent storage. (My install server now has
- 704 MB of install images and 469 PTFs.)
-
- I wish IBM would provide a one-line heading for each PTF, because I now
- keep track of this information by myself, trying to decide which few
- lines of the 200+ lines in the fixinfo file apply to this PTF.
-
- In the end I don't keep each machine up to date, but simply install the
- fixes to fix the reported problems, so every one of the 59 machines I
- support has a different level of fixes applied.
-
- And I used to just apply and commit a fix, but now I only apply and
- wait at least a month before the commit.
