3 HP-UX patch overview

Patch-related concepts

Patch identification

HP assigns each HP-UX patch a unique identification or patch ID. Each HP-UX patch ID has the form PHXX_#####, where:

PH is an abbreviation for Patch HP-UX

XX is replaced with one of the following values for the HP-UX area being patched:

CO = command patches

KL = kernel patches

NE = network patches

SS = patches related to all other subsystems

##### is replaced with a unique four- or five-digit number.

In general, the numeric portion of the patch ID is higher for more recently released patches.

HP-UX software structure

To understand some of the topics presented in this chapter, you should have a basic understanding of the structure of HP-UX software. Patches are part of this software structure. You will also need to use Software Distributor.

The following list provides an overview of the Software Distributor for HP-UX (SD-UX) software objects that compose HP-UX software.

Fileset

A fileset is a grouping of one or more files contained in a product. A fileset groups a subset of a product's files into a manageable unit.

Filesets include the files and control scripts that make up a product. For more information about control scripts, see the Software Distributor Administration Guide on the HP Business Support Center website at http://www.hp.com/go/sd-docs.

Filesets must exist within a product.

Although a patch has a unique name, the names of the filesets contained in a patch match the corresponding base filesets that they patch.

Product

A product is a software object that is packaged and distributed for users to acquire and install.

Products are composed of one or more filesets and might additionally contain one or more control scripts.

A product can exist either within a bundle or as its own entity.

Bundle

A bundle is an encapsulation of products into a single software object.

Bundles are, sometimes, optional software objects.

Product objects are included in a bundle by reference only.

If the products within the bundle are all patches, the bundle is known as a patch bundle.

For more information about these software objects, see the Software Distributor Administration Guide on the HP Business Support Center website at http://www.hp.com/go/sd-docs.
