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. 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. 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.

See release 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.
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. Sometimes referred to as official patches, release patches are intended for worldwide distribution and can be safely used on any customer's system within the guidelines documented in the patch kit.
See also customer-specific patch (CSP)
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.
On Version 5.0A and higher systems, you use a rolling upgrade to patch a cluster or to update the Tru64 UNIX operating system or TruCluster Server software on a cluster. The procedure is same for both types of upgrades -- the only difference is the command you run during the install stage of the rolling upgrade procedure.
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.
