HP Tru64 UNIX Version 5.1B-2 and Higher: Patch Kit Installation Instructions


»Table of Contents
Content starts here

Published: December 2006


This guide provides instructions for installing, removing, and working with Release patch kits, Customer-Specific patch kits (CSPs), and Early Release patch kits (ERPs) using the dupatch utility, which is included with HP Tru64 UNIX patch kits.

The information in this guide provides examples and descriptions for the Inclusive patch kit structure, which was introduced with Version 5.1B-2. If you are working with earlier patch kits, we recommend using the instructions that came with your patch kit. We also provide a guide named Installation Instructions for Pre-Inclusive Patch Kits on the patch documentation Web. See “Patch Process Resources” for information.

See the Patch Summary and Release Notes document for the kit you are installing for important information you need to know about when installing or removing the patch kit. The Patch Summary and Release Notes document also provides information about individual patches and information that is specific to a patch kit.
