1    Release Notes

This chapter provides information that you must be aware of when working with Tru64 UNIX 4.0F and TCR 1.6 Patch Kit-0001.

1.1    Required Storage Space

The following storage space is required to successfully install this patch kit:

Base Operating System

TruCluster Software products

1.2    New dupatch Features

The following sections describe new features of dupatch.

1.2.1    dupatch-based Patch Kits for ASE and TCR Patches

Patches for ASE and TCR are now installed, removed, and managed through dupatch. The ASE and TCR patch kits have been converted to dupatch-based patch kits and distributed in the same patch distribution as the applicable operating system.

The multi-product support within dupatch is most visible when installing or removing patches. dupatch will display a list of the products which are on the system and in the patch kit, allowing the user to select one or more products before proceeding with patch selections.

You must load the new patch tools provided in this patch kit. See the Patch Kit Installation Instructions for more information.

Since all prior ASE and TCR patches have been installed manually, you must set the system patch baseline. See the Patch Kit Installation Instructions for detailed information.

1.2.2    New Cross-Product Patch Dependency Management

The dupatch utility now manages patch dependencies across the Tru64 UNIX operating system, ASE, and TCR patch kits. An example of patch cross-product dependency handling for a system with both Tru64 UNIX 4.0F and TCR 1.6 installed follows:

1.2.3    Patch Special Instruction Handling by dupatch

The format and content of the per-patch special instructions has been revised to make it easier to use. The special instructions are now displayed when patches are removed. The per-patch special instructions are viewable through the dupatch documentation menu.

1.2.4    Patch Tracking and Documentation Viewing

The patch tracking and documentation viewing features within dupatch can now be used in multi-user mode by non-root users. See the Patch Kit Installation Instructions for more information.

From the dupatch patch tracking menu you can now list the patch kits from which patches installed on your system originated.

1.2.5    System Patch Baselining

The system patch baselining feature of dupatch has been improved. Phase 4 now reports all missing or unknown system files regardless of their applicability to the patch kit. This will help you identify the origin of manually changed system files. See the Patch Kit Installation Instructions for more information.

1.2.6    New Command Line Interface Switches

The dupatch command line mode contains the following new switches:

Any error on the command line will cause the help information to be displayed on the screen.

If any mandatory switch is missing when using the command line interface, the command fails with the appropriate usage message. Once you select the command line interface, dupatch will not go into interactive mode. Prompting is no longer mixed with the command line interface.

1.2.7    Compatibility Between Revisions of dupatch

The new dupatch will work with older revisions of dupatch-based patch kits.

The older revisions of dupatch, however, rev 15 and lower, do not know how to install, remove, or manage patches from the new style patch kits. Please ensure that you load the new patch installation tools when you receive this patch kit. See the Patch Kit Installation Instructions for more information.

1.3    Known Problem with dupatch

The following list of dupatch error messages will be created when executing dupatch. This problem will be addressed in a future release of dupatch.

After installation of the V4.0F Patch Kit-0001, the target root contains these three files:

# ls -l PCI*
-rw-r--r--   1 root     system         0 Jun  1 18:35 PCITMP1
-rw-r--r--   1 root     system         0 Jun  1 18:35 PCITMP2:
-rw-r--r--   1 root     system         0 Jun  1 18:35 PCITMP3

Also, the root directory of the system installing the patches contains the files:

# ls -l /P_P*
-rw-r--r--   1 root     system        54 Jun  1 18:35
/P_ProdCacheInfo.tmp1
-rw-r--r--   1 root     system         0 Jun  1 18:35
/P_ProdCacheInfo.tmp2

These are error messages from dupatch that are not being properly trapped. This problem will be addressed in a future release of dupatch.
