Patch Introduction
HP-UX patch names have the following format:
PHxx_yyyyy
where:
PH Patch HP-UX
xx area patched
CO general HP-UX commands
KL Kernel Patch
NE network specific patches
SS all other subsystems: X11, Starbase, etc
yyyyy unique number
The number yyyyy is unique across all areas (or categories). The installation of kernel and
networking patches modifies the kernel (/stand/vmunix) and is therefore always followed by a
reboot.
Commands and subsystem patches do not enforce a reboot of the system but applications
depending on the patched files may need to be restarted. You will find detailed information about
this in the “special installation section” of the patch text.
Differences in patching between the HP-UX releases
Changes from UX 10.20 to UX 11.00 - Patch as individual
There has been a significant change in the way patching works from HP-UX 10.X to 11.X.
Whereas with 10.X a patch was nothing more than a regular product we can distinguish between
regular products and patches at UX 11.X. This has several advantages. The basic differences
between 10.X and 11.X patching are:
 Patches are recognized by their „patch“ attribute and not by their naming (eg. PHKL_12345).
 There is a strict relation between a product and the patch that affects the filesets of this
product. So each time you install, update or remove a product the corresponding patch(es) are
also installed, updated or removed. E.g. if you install a product from a certain depot, SD-UX
automatically installs the appropriate patches for the product if they are also contained in the
depot.
 Patches are classified into certain categories which allows a more flexible way of patch
