This
chapter introduces you to the
dupatch
utility for installing,
removing, and managing patches.
It also provides information you must be aware
of when installing patches.
See
Chapter 4
for instructions
on installing and removing patches from the Tru64 UNIX operating system and
the TruCluster software products.
2.1 Overview of dupatch
All Tru64 UNIX and TruCluster software patches are installed,
removed, and managed using the
setld-based
dupatch
utility, which provides
you with menus that step you though the various tasks.
For clustered systems running TruCluster Server Version 5.0A or higher,
dupatch
is run in conjunction with the rolling upgrade procedure
described in
Chapter 5.
The
dupatch
utility also provides a command-line
interface from which you can specify options to invoke all functions, except
for baselining.
The functions have the same operation and definition as the
menu-driven interface.
For information about using the command-line interface,
see
Appendix C
and the
dupatch(8)
With
dupatch, you can perform the following actions:
Install and remove all or selected patches.
View the patch-specific documentation.
View patch tracking and management information.
Establish a baseline for systems that had manually installed system files placed on them.
Directions for enabling or disabling patches are provided after the successful installation or removal of all selected patches (for example, kernel rebuild and system reboot).
The
dupatch
utility also manages
the system inventory for Tru64 UNIX and TruCluster software patches.
This
enables patch tracking and management of patch activity such as:
Tracking current
dupatch-installed patches.
Ensuring correct handling of customized system configuration
files so that customizations are not lost (for example,
conf.c).
These files are also referred to as system-protected files (.new..).
Validating patch applicability to existing system files (collision detection).
Because
dupatch
manages patch interdependencies,
direct
setld
installations and deinstallations (setld
-l
-d) are disabled.
2.2 Log Files Created by dupatch Processes
The
dupatch
utility captures patching activities
in the following log files:
/var/adm/patch/log/session.log
Every time you run
dupatch
it creates a session log
that captures
dupatch
activities.
The
session.log
files from the previous 25 sessions are saved.
The order is first
in, first out, with
session.log.25
as the oldest file.
/var/adm/patch/log/Dupatch_load_Date.log
When you run
dupatch
from the newly untarred kit
or from the mounted Tru64 UNIX Patch CD-ROM,
dupatch
determines if the patch distribution contains new patch tools, and loads
them if necessary.
This log file has a name similar to this:
Dupatch_load_2000Jul1:15:43:35.log
/var/adm/patch/log/baseline.log
When you run the system baselining feature,
dupatch
creates a baseline log.
The
session.log
files from the
previous 25 sessions are saved.
The order is first in, first out, with
baseline.log.25
as the oldest file.
/var/adm/patch/log/event.log
When patches are installed or removed, an event log captures that information.
Only one copy of the file is updated each time patches are installed or removed.
The information in the patch event log is not available through the
dupatch
user interface, but the log is a text file that you can
view with a command such as
more.
The following list describes
the types of information an event log provides, although the format and content
are subject to change.
Example 2-1
shows a typical
event log.

2.3 Patch Installation and Removal
When installing and removing patches,
dupatch
manages
the following:
The applicability of patches
Patch dependencies
Patch reversibility
System inventory changes for patches
Patch applicability to the existing system files is done on a file-by-file basis for each patch. This ensures that the installation of a patch will not degrade or crash the system. The installation of a patch is blocked if any system files to be replaced by a patch are not valid predecessors of the patch files.
Patch applicability also enables consistency checking and reporting for the installation of Tru64 UNIX and TruCluster software patches.
In all cases where a patch is blocked, informative messages are provided to assist you in determining how to proceed. Appendix A lists common error messages and suggested corrective actions.
The installation of a patch is blocked if any of the following conditions exist:
The underlying software product subset is not installed; for example, if the applicable Tru64 UNIX or TruCluster software release subset is not installed.
The
setld
inventory is inconsistent with
the existing system files.
This occurs when an operating system or TruCluster
software
setld
subset is installed and individual operating
system files that are part of that subset are moved, deleted, or replaced.
If any of the existing system files (files that are targeted
to be updated by a patch) have changed and cannot be related to previous versions
of the patch.
This ensures that operating system files that change due to
other explicit system administrator action (for example, layered product patches
or non-dupatch
installed CSP installations) are not inadvertently
overwritten.
You must take special action, through the baseline feature, to
enable patch installation in this situation.
2.3.2 Patch Dependency Management
Selective patch installation and removal is allowed in the Tru64 UNIX
and TruCluster software patch kits.
When patches are selectively chosen,
dupatch
provides warning messages regarding other dependent patches
requiring installation or removal for correct system operation.
The
dupatch
utility manages
the dependencies between patches within each product patch kit and across
product patch kits.
For example,
dupatch
manages the following
kinds of dependencies when patches on systems where both Tru64 UNIX Version
4.0F and TruCluster software Version 1.6 are installed or removed:
Patch dependencies within a product patch kit
If, for example, you choose to install Tru64 UNIX 4.0F Patch 1.00
and it depends upon Tru64 UNIX 4.0F Patch 5.00, which is not already installed
or chosen for installation, the
dupatch
preinstallation
check will warn you of the dependency and prevent the installation of Tru64 UNIX
4.0F Patch 1.00.
If the patch selections are reversed,
dupatch
will
warn you and prevent installation of the chosen patch.
Patch dependencies across product patch kits
If, for example, you choose to install Tru64 UNIX 4.0F Patch 1.00
and it depends upon TruCluster 1.6 Patch 17.00, which is not already installed
or chosen for installation, the
dupatch
preinstallation
check will warn you of the dependency and prevent the installation of the Tru64 UNIX
4.0F Patch 1.00.
If the patch selections are reversed,
dupatch
will
warn you and prevent installation of the chosen patch.
Note
Even though selective patch installation capabilities exist, Compaq recommends that you install all patches in each kit for Tru64 UNIX and TruCluster software to prevent the occurrence of known and corrected software problems.
Enabling patch reversibility during patch installation allows you to revert the system to its state prior to the installation of a particular patch.
By default, the reversibility installation option is set to enable reversibility for patches. If you choose to make patch subsets nonreversible, then those patches will become nonremovable upon the successful installation of those patches.
Note
Customer-Specific patches are forced to be reversible when the CSP kit is manufactured. This forced reversibility overrides the reversibility option provided by
dupatchduring installation.
Patch reversibility is dependent upon saving the existing system files
that will be updated by the patch.
Saving these files requires the availability
of adequate storage space in
/var/adm/patch/backup, which
can be a mount point for a separate disk partition, an NFS mount point, or
a symbolic link to another file system.
This allows you to configure your
system to reduce the impact on system disk space for the
/,
/usr, and
/var
partitions.
To further reduce the storage space required to save existing system
files, the patch kits for Tru64 UNIX and TruCluster software use the
gzip
utility to save each patch file in a compressed tar image.
This results in a file with a name like
filename.tar.gz.
The
dupatch
utility checks for the required storage
space prior to patch installation.
Patch installation is prevented if adequate
backup space is unavailable.
2.4 Viewing the Patch Documentation
When you select the Patch
Documentation item of the main menu,
dupatch
returns a
menu that gives you access to different information:
Problem summaries
Provide brief descriptions of the problems corrected by the patches. You can view the problems corrected by installed patches or by patches available from a specific kit.
Full descriptions
Provide complete descriptions of the problems corrected by the individual patches. You can view the problem descriptions for installed patches or for patches available from a specific kit.
Special Instructions
These files describe special instructions you need to be aware of for individual patches. You can view the instructions for installed patches or for patches available from a specific kit.
Report identifiers
Revision control strings
The following output shows the Patch Documentation menu and a typical session:

2.6 Handling Manually Installed System Files with Baselining
The
dupatch
baselining process 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.
This section
provides an overview of the baselining process.
See
Section 4.7
for instructions on setting a baseline.
Unknown system files occur when the files are replaced through non-standard system file installation methods such as the following:
The manual installation of system files such as system administration customizations or manually installed patches
Using the
setld
utility to install system
files from user-derived
setld
subsets
Using the
setld
utility to install files
for layered software products
Changes that result from weak system control programs (usually
named
file.scp)
Missing system files result from a root user manually deleting system
files that were installed during a standard full or update installation procedure
or with the
dupatch
utility.
The file is removed but the
system inventory records are still in place.
Unknown and missing system files will block patch installations until you take corrective action. However, before taking any action, it is important that you understand the origin of the unknown system files or why missing files are no longer present on your system. Changing the system without this knowledge could leave your operating system or layered product software environment in an inconsistent and nonoperational state.
For example, a file whose origin is unknown that is blocking the installation of a Release patch could be part of a manually installed Customer-Specific patch that is not contained in the Release patch. Removing that one file will disrupt the operation of your CSP and possibly the operation of the system.
When you run the
dupatch
system baseline feature,
a baseline log file is captured in
/var/adm/patch/log/baseline.log.
(See
Section 2.2
for information about log files.)
You may need to set the patch baseline for your system if you have
manually installed system files or if
dupatch
informs you
that patch installation is blocked by system files that are missing or unknown.
Warning
Misusing the baselining feature can cause serious problems with your system. It is important to be aware of the following potential problems:
Enabling baselining to override its applicability checking could leave your operating system or layered product software environment in an inconsistent and nonoperational state.
Enabling baselining to update your system sets a new baseline for your operating system or TruCluster software environments. You will not be able to revert to the previous system state for manually installed patches that were marked as installed by baselining. Compaq recommends that you backup your
/,/usr, and/varfile systems before enabling system updates throughdupatchbaselining.
Baselining is divided into five phases that provide system information
and optionally allow you to take actions that change the patch baseline of
your system.
You can run through all phases of baselining to get the system
analysis without enabling changes to your system.
You can run baselining in
multiuser mode when you are the root user.
2.6.1 Phase 1 - System Evaluation
The primary goal of Phase 1 is to evaluate your system relative to the patch kit that is being installed. However, the baselining feature will report all missing and unknown files to assist you in better understanding the state of the changed files on the system.
The rest of the baselining phases use the information gathered in Phase 1 to inform you of any installation conflicts for patches contained in the patch kit.
The amount of time needed to evaluate the state of the system varies
greatly depending on the size of the patch kit, the version of the software
product, and the performance of the system.
2.6.2 Phase 2 - Patch Layered Product Conflicts
Phase 2 reports information for patches whose installation is blocked by system files that were installed by layered products.
Baselining will not override layered product patch installation collision detection mechanisms as it is likely that the layered product or application customizations are not contained in the patch. Installation of the patch in this situation would leave the layered product or application nonoperational.
To resolve this situation, contact your layered product or application
Customer Services or Compaq Services if you have purchased Business
Critical Services.
2.6.3 Phase 3 - Identifying Manually Installed Patches
Phase 3 reports patches that exactly match existing files on your system
that are not marked as
installed
by the system inventory.
For example, in earlier kits, TruCluster software Release patches were installed
manually.
This phase will report any manually installed Release patch files
that exactly match a patch contained in the current
dupatch-based
TruCluster software patch kit.
You can optionally enable
dupatch
to mark these patches
as
installed, which involves copying valid
setld
database information to your system.
The
dupatch
utility will copy the appropriate
patch_subset.inv,
patch_subset.scp, and
patch_subset.ctrl
files into place for these patches.
If you do not want to enable
dupatch
to mark these
patches as installed, you must manually remove the patched system files so
the normal
dupatch
installation can install the affected
patches.
2.6.4 Phase 4 - Handling Missing or Unknown Files on Your System
Phase 4 reports information about any unknown and missing system files. These files should be considered as intentional customizations which are important to correct system operation. As such, care should be taken to understand why system files have been customized.
Before enabling any patch installations in Phase 5, review the information reported in Phase 4 against your log of manual system changes to ensure you understand why the system was intentionally customized and to determine how to proceed. In some cases you may need to remove customizations to ensure proper system operation.
To assist you in identifying the origin of changed system files, baselining now reports all missing or unknown system files.
The following sections provide general guidance for some of the normal
situations where system files are intentionally customized manually.
2.6.4.1 Manually Installed Customer-Specific Patches
In response to a problem report, you may receive a manually installable Customer-Specific patch from your service provider. Customer-Specific patches are a set of compatible files that deliver fixes to the problems you reported. Additionally, the patch may include instrumentation necessary for debugging purposes.
If your system was customized through a manual installation of Customer-Specific
patches, you must ensure that the fixes delivered by the Customer-Specific
patches are included in the current Release Patch Kit before enabling
dupatch
to overwrite any unknown or missing system files.
Warning
If you are unsure if the Customer-Specific patch is included in the Release Patch Kit, do not enable
dupatchto overwrite the manually installed Customer-Specific patch. If you must install the Release patch being blocked by a Customer-Specific patch, contact your service provider for assistance.
If the unknown or missing files are attributable to manually installed Customer-Specific patches that are included in a Release Patch Kit, perform one of the following steps:
If all Customer-Specific patch files are overwritten by the
patches noted in Phase 5, you can safely enable
dupatch
to overwrite applicable missing or unknown system files.
If some of the Customer-Specific patch files are not overwritten by the patches noted in Phase 5, contact your service provider for assistance.
To determine if your Customer-Specific patch is included in the Release
Patch Kit, refer to the
Patch Summary and Release Notes
for the Release Patch Kit.
See
Section 1.4
for information about viewing patch documentation on the Web.
2.6.4.2 Manually Installed Release Patches
For some software products, manual installation has been the practiced method for patch installation. For example, patches for TruCluster software used to be installed manually.
You must determine whether the fixes delivered by the manually installed
Release patches are included in the current
dupatch-based
Release Patch Kit before enabling
dupatch
to overwrite
any unknown or missing system files.
Once you have made this determination,
proceed as follows:
If the unknown or missing system files are attributable to
the manual installation of Release patches and those patches are included
in the current
dupatch-based Release Patch Kit, you can
safely enable
dupatch
to overwrite applicable missing or
unknown system files.
If the unknown or missing system files are not attributable to manual installation, you must understand the origin of the unknown or missing system files by reviewing the information reported in Phase 4 against your log of manual system changes to ensure you understand why the system was intentionally customized, and to determine how to proceed.
2.6.4.3 User Customized Commands and Utilities
Periodically, system administrators of production computing environments replace Tru64 UNIX commands or utilities with freeware or their own customized version of the command or utility. In this situation you must ensure the unknown or missing files are attributable to intentional replacement of commands, utilities, or other system files.
If the unknown or missing system files are attributable to the replacement
of commands, utilities, or other system files with customized versions for
the computing environment, do not enable
dupatch
to overwrite
the manually installed customized files.
Instead, determine the reason for
the customization and then decide how to proceed.
2.6.5 Phase 5 - Enabling dupatch to Overwrite Changed System Files
Phase 5 reports patches that are blocked due to missing or unknown system
files, and optionally allows you to override the
dupatch
conflict management mechanism so the
dupatch-based patch
may be installed.
For each patch that is blocked by a missing or unknown system file you are presented with the following information:
Software product identifier
Patch category
Patch identifier
Patch subset description
The list of unknown and missing files that block the patch installation
The origin of all other files contained in the patch
Optionally, you can enable
dupatch
to override the
collision detection mechanisms and install any of these patches.
Use the missing
and unknown file information presented in Phase 4 and your system administration
log of manual system changes to make Phase 5 patch installation enabling decisions.
Warning
Do not enable
dupatchto install patches over missing or unknown system files for which you do not know the origin. Doing so may leave your operating system and TruCluster software environment in an inconsistent and nonoperational state.
