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.
Any patch 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.
Also referred to as test patches and prerelease patches, customer-specific patches may not be useful for another customer's system.
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.
A Tru64 UNIX installation that creates new file systems and loads
a full copy of the operating system from the kit onto a system. Any other
version of the operating system, any layered products, and any patches
that previously existed on the system are overwritten. A full installation
does not preserve system customizations (for example, user or data files)
because the root (/),
/usr, and
/var file systems
are re-created during the process.

The coding inserted in a file intended for display on a World Wide
Web browser that tells the browser how to display a Web page's words and
other elements. The markup is done with tags, which are command words enclosed
in angle brackets. For example, the tag
<p> creates a new paragraph.
HTML (hypertext markup language) files are text (ASCII) files. The documentation
provided with the Tru64 UNIX patch kits is provided in HTML files for viewing
on a Web browser.

A manually installed patch is a patch kit that is not packaged as
a dupatch
based kit. It has a minimal amount of management functionality associated
with it - just enough to track the patch on the system. Typically a customer
will never see this type of packaging.
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.
A file-by-file check of system files to determine whether a patch
might cause a a system to be degraded or crash. The installation of a patch
is blocked if any system files to be replace by that patch are not valid
predecessors of the patch files.
A file type recognized by the Adobe Acrobat Reader, which provides
an easy way to view and print documentation. As the next generation of
Adobe's PostScript format, PDF files have become a standard way of distributing
documentation, especially on CD-ROM and over the Internet. The Tru64 UNIX
patch documentation is provided in PDF and HTML formats. The Acrobat Reader
is provided on the Tru64 UNIX Documentation CD-ROM of Version 4.0E and
higher. It is also available at the Adobe Web site,
http://www.adobe.com/

Any patch that is included in a Tru64 UNIX patch kit. Also called
official
patches, released patches are intended for worldwide distribution and can
be safely used on any customer's system within the guidelines documented
in the patch kit.
A software upgrade of a cluster that is performed while the cluster
is in operation. One member at a time is rolled and returned to operation
while the cluster transparently maintains a mixed-version environment for
the base operating system, cluster, and Worldwide Language Support (WSL)
software. Clients accessing services are not aware that a rolling upgrade
is in progress.
A rolling patch uses the same procedure as rolling in a new release of the base operating system and cluster software. The only difference is whether you run installupdate, dupatch, or both during the installation stage.
An interactive program for installing and managing software subsets.
Software products are organized into subsets that can be loaded, deleted,
inventoried, and configured. The load operation reads software from disk,
tape, CD-ROM, or an Internet installation server. The patch installation
tool,
dupatch,
is based on the
setld program.
A file created with the
tar command that saves and
restores multiple files in a single file. Tru64 UNIX patch kits are provided
as tar files (except for kits included on the Tru64 UNIX CD-ROM).
A type of installation that preserves disk partitions, file systems,
file customizations, the network, print, and mail environments, user accounts,
user created files, and any other system setup you may have done. If software
patches had been applied to the operating system, it would not be necessary
to remove the patches before beginning the update process, which is designed
to update and reinstall any software fixes or features that were supplied
in release patches.
