Changes Made in Version 5.1B-2

All or none installation

When you install an inclusive patch kit, you must install all patches; you can no longer select specific patches to install. By making the installation of all patches mandatory, you can patch with greater confidence that the process will be problem free.

Before a patch kit is released, it is tested on many types of systems and system configurations. This testing continues until we are assured that the patches perform the tasks they were designed for and do not introduce new problems. It is not possible to achieve this type of testing on every possible combination of individually selected patches.

Substantially reduced installation time

The installation process for inclusive patch kits can reduce the time it takes to install the patches by as much as half from what you are used to. For large, clustered systems, the difference can be several hours faster.

Fewer patches displayed

Because of the way these new patch kits are designed, you will see many fewer patches listed by dupatch during the installation process. For example, a partial listing you see will be similar to the following:

- Tru64_UNIX_V5.1B / Security Related Patches:
      * Patch 27001.00 - SP04 OSFACCT540

      * Patch 27002.00 - SP04 OSFADVFS540 (SSRT2275)

      * Patch 27003.00 - SP04 OSFADVFSBIN540

In the old-style patch kits, these three patches might have consisted of perhaps 20 individual patches being displayed. The difference is not in the content of the kits, but rather in the way the patches are packaged and installed. In this example, the SPO4 identifies the patch as belonging to Version 5.1B-2 (Patch Kit 4), the OSF...540 identifies the subset the patch is included in, and the SSRT2275 indicates a type of security patch.

All or none patch removal

As with the installation process, if you want to remove a patch, you must remove all of them. That is, you can no longer select individual patches for removal.

Patches for Worldwide Language Support (WLS) subset

The inclusive patch kits deliver patches that may be required for the WLS subset. As with the TruCluster Server patches, the WLS patches will only be installed if you have the WLS subset installed. See Chapter 5 “Worldwide Language Support Patches” for information about WLS subset patches.
