2    Patch Management Utility

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) reference page.

With dupatch, you can perform the following actions:

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:

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:

2.3    Patch Installation and Removal

When installing and removing patches, dupatch manages the following:

2.3.1    Patch Applicability

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:

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:

2.3.3    Patch Reversibility

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 reversiblity overrides the reversibility option provided by dupatch during 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:

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:

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:

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 official patch kit, do not enable dupatch to overwrite the manually installed customer-specific patch. If you must install the official 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:

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, until recently, patches for TruCluster software had been manually installed.

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:

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:

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 dupatch to 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.
