HP Tru64 UNIX Version 5.1B-2 and Higher Patch Kit Installation Instructions (March 2009)

Glossary
baselining A dupatch feature that looks at the files installed on a system, compares them to the files it
expects to find, and prevents the installation of any patch files that might cause an incompatibility
among system files.
Customer-Specific
Patch (CSP) Kit
A patch kit that is developed and made available to resolve a problem for a specific customer.
A Customer-Specific patch is developed with prior knowledge of that customer's unique
hardware and software configuration and environment. Customer-Specific patches may not
be useful for another customer's system. An Early Release patch is a type of CSP.
See also Early Release Patch (ERP) Kit, Release Patch Kit.
dupatch A utility included in a patch kit that installs, removes, and manages patches for Tru64 UNIX
and TruCluster software products. This utility is installed and left on the system through the
successful installation of a patch kit.
Early Release
Patch (ERP) Kit
A patch kit that contains a patch or patches that will be included in a Release Patch Kit that is
still under development. ERPs, which are a type of Customer-Specific patch, are provided by
HP to help customers who have an immediate need for some specific functionality that will be
included in an upcoming Release Patch Kit.
See also Customer-Specific Patch (CSP) Kit, Release Patch Kit.
force install A term somtimes used to describe the abilility of the baselining procedure to enable the
installation of patches that are blocked by the intallation procedure.
inclusive patch
kit
See new style patch kit.
new style patch
kit
Also called an inclusive patch kit, a new style patch kit is a Release Patch Kit that provides an
improved way of delivering patches. Among the ways that a new style patch kit differs from
its predecessors is that it requires an all or none installation and removal of the patches in that
kit. The first Tru64 UNIX new style patch kit was Version 5.1B Patch Kit 4 (Base Level 25).
See also Release Patch Kit.
no-roll patching A process that patches your cluster in one operation and requires only one reboot of the whole
cluster to complete the operation. This method was developed for mission-critical environments
to provide a way to apply patches quickly, with a minimum amount of down time.
The no-roll patch process is a modification of dupatch; that is, all patches are installed or
removed entirely using the dupatch utility, as opposed to the clu_upgrade and dupatch
utilities used in the rolling upgrade procedure. The no-roll process conducts significantly fewer
operations than the rolling upgrade procedure.
See also rolling upgrade.
official patch See Release Patch Kit.
old style patch kit See new style patch kit.
patch A file or a collection of files that contain fixes to problems. When possible, patches are merged
together into one patch if they have intersecting files or codependencies. A patch may correct
one or more problems.
Each patch is packaged in its own setld subset. The subsets are managed by a utility named
dupatch.
patch
applicability
A file-by-file check of system files to determine whether a patch might cause a system to be
degraded or crash. The installation of a patch is blocked if any system files to be replaced by
that patch are not valid predecessors of the patch files.
Release Patch Kit A patch kit that HP provides to modify a specific version of the Tru64 UNIX operating system
and TruCluster software. Sometimes referred to as official patch kits, Release Patches Kits are
intended for worldwide distribution and can be safely used on any customer's system within
the guidelines documented in the kit. The patches in a Release Patch Kit are referred to as
Release patches.
