Patches

Patches are given in the tables below. Each HP-UX version has its own table, organized by WLM version.

See the installation notes below on steps to complete before and after installing patches.

To determine what version of HP-UX you have, enter the following command:

# uname -r

Installation notes

Before installing patches

  1. Read each patch's installation instructions:
    Each patch comes with a .txt file named using the patch number. For example, patch PHSS_26845 has a file named PHSS_26845.txt. Be sure to read the "Special Installation Instructions" section of the .txt file for each patch you are going to install.
  2. Shut down WLM:

    # wlmd -k
  3. After installing patches, restart WLM using the most recent configuration:

    # wlmd –A

Patch types

  • PHCO: HP-UX COmmand patch
    PHKL: HP-UX KerneL patch
  • PHNE: HP-UX NEtworking patch
  • PHSS: HP-UX SubSystem patch
    (PHSS patches on this page are specific to WLM or PRM, which WLM uses)

The patches listed are the patches available at the time of release. The listed patches may have since been superseded. If a patch you need has been superseded, download the superseding patch.

Minimize the number of system reboots when installing kernel patches (PHKL_* patches) by creating a software depot.
