What is the naming convention used for HP-UX patch
A patch name consists of the characters "PH" (Patch HP-UX), followed by
a two-character type-identifier, followed by an underscore, followed by
a four or five-digit number.
The currently defined patch types are:
CO - COmmands & libraries
KL - KerneL
NE - NEtworking
SS - SubSystems
An example name of a Kernel patch name would be "PHKL_23507."
Kernel patches always require a system reboot, so that the newly updated
kernel can be loaded. Many Networking patches (PHNE*) also make
modifications to the kernel, and hence require a reboot.
Note that the numerical portion of any given patch name is unique, among
ALL patches. So there would never be a patch named "PHCO_23507", in
addition to a patch named "PHKL_23507." This lends itself nicely to
grepping for a particular patch (ie - to see if "PHKL_23507" is
installed, one could use "swlist -l product | grep 23507"
