Patch Software Objects and Attributes
SD contains attributes specifically for handling patch software. The
following attributes are available to all software levels (bundles,
products, subproducts, and filesets).
category objects
A software collection can contain a list of category
objects, which are used as a selection mechanism.
Category objects are identified by the keyword category
and contain additional information about this category
(a title, tag, and a description of the category). The
category_tag attribute points to a particular category
object and can appear within a product, bundle,
subproduct, or fileset.
All software objects with the attribute of is_patch set
to true are automatically assigned the category of
patch. (Note that category objects and the
category_tag attribute can be used independently of
patches.)
See “Category Specification” on page 324 for a complete
description of category objects.
is_patch Indicates that a software object is identified as a patch.
The default is false. Only filesets with the is_patch
attribute have patched files. Other levels can be
identified as patches for the listing utilities to facilitate
identification of patch software at any level.
All software objects with the attribute of is_patch set
to true are automatically assigned a category of patch.
Patch Fileset Attributes
Patch filesets generally operate like normal filesets. Differences are:
• Patch filesets have an explicit ancestor.
• Patch filesets can be installed in the same session as their base, or
ancestor, fileset. (The base fileset is always installed first.)
• Patch filesets can be rolled back.
• Patch filesets maintain catalog information to support these
features.
