HP Tru64 UNIX and TruCluster Server Version 5.1B-5 Patch Summary and Release Notes (March 2009)

B Prior Patch Installation Changes
Beginning with Version 5.1B-2, we changed the way Tru64 UNIX patch kits are installed
and removed, and Version 5.1B-3 introduced additional changes. The following sections
describe these changes.
See the Patch Kit Installation Instructions manual for complete information about
installing, removing, and managing Tru64 UNIX patch kits.
B.1 Changes Made in Version 5.1B-3
If you did not install Version 5.1B-3 but have installed earlier kits, you will see the
following differences in the kitting process:
• Before you can install this kit you must accept the conditions included in the license
that the dupatch utility displays. You can read this license in
Appendix C “Component Licensing”.
• You can delete the patch kit by kit name rather than by specifying individual
patches. With the introduction of this feature, you can easily delete patches
interactively using the dupatch utility or from the dupatch command line. This
feature also works on pre-Version 5.1B-5 kits.
• You can delete patches in multi-user mode.
• You can force the installation of the patch kit even if file conflicts exist. This feature
is an extension of the dupatch baselining feature.
• A new command-line option, Patch Level, provides a single command that provides
a full description of the patch kits, CSPs, and ERPs installed on your system.
B.2 Changes Made in Version 5.1B-2
If you did not install versions 5.1B-2 or 5.1B-3 but have installed earlier kits, you will
see the following differences in the kitting process:
• All or none installation
When you install an inclusive patch kit, you must install all patches; you can no
longer select specific patches to install. By making the installation of all patches
mandatory, you can patch with greater confidence that the process will be problem
free.
Before a patch kit is released, it is tested on many types of systems and system
configurations. This testing continues until we are assured that the patches perform
the tasks they were designed for and do not introduce new problems. It is not
possible to achieve this type of testing on every possible combination of individually
selected patches.
• Substantially reduced installation time
The installation process for inclusive patch kits can reduce the time it takes to
install the patches by as much as half from what you are used to. For large, clustered
systems, the difference can be several hours faster.
