HP UX Patch Management manual Glossary, Ancestor

Glossary

	This glossary defines key terms related to patching that are used in this book. HP
	recommends the Software Distributor Administration Guide on the HP Business Support
	Center website at http://www.hp.com/go/sd-docs for additional terms.
ancestor	An ancestor of a patch is the preexisting software that is being modified or replaced by the
	patch.
applied	One of four possible states in which a patch is first installed. When a patch is installed, by
	default it has the patch_state of applied. Other patch states include committed,
	committed/superseded, and superseded.
base software	The software that will be modified by a patch.
bundle	An encapsulation of products, subproducts, and filesets into a single software object. Bundles
	are a convenient way to group software objects for easy selection. When a bundle is specified
	in a Software Distributor operation, all products or filesets contained in that bundle are included
	in the operation. If the filesets within the bundle are patches, this is known as a patch bundle.
	See also patch bundle.
catalog, catalog	An area within a depot that contains all the information needed by SD-UX to define the
directory	organization and contents of the products stored in the depot. The catalog (or catalog directory)
	includes a global index file and a directory of information for each product version in the depot.
category tags	See patch category.
committed	The patch state in which the patch is applied and rollback files have been deleted.
committed/	The patch state in which the patch is both committed and superseded.
superseded	See also superseded.
control script	An optional script that is run during software installation, software removal, or software
	configuration.
corequisite	A dependency in which a fileset requires that another fileset be installed or configured at the
	same time. For example, if fileset A requires that fileset B is installed at the same time, fileset
	B is a corequisite.
	See also dependency, prerequisite.
cumulative patch	Each new patch contains all aspects of all its preceding patches. Patches for HP-UX products
	are always cumulative.
dependency	A relationship between filesets in which one requires another in a specific manner. For example,
	before fileset A can be installed, it might require fileset B to be installed. SD-UX supports
	corequisite and prerequisite dependencies.
	See also dependent.
dependent	A fileset that has a dependency on another fileset. For example, if fileset A depends on fileset
	B, then B is dependent or has a dependency on A.
depot	A repository of software products and a catalog, organized so that SD-UX commands use it as
	a software source. The contents of a depot reside in a directory structure with a single, common
	root.
depot source	See depot.
directory depot	The directory on a target host in which a depot is located. The default is /var/spool/sw.
DRD	See Dynamic Root Disk.
Dynamic Root	Patches HP-UX systems, reduces system downtime for software maintenance, provides the
Disk	ability to install and manage patches on an inactive system image while the system is up and
	running, allows most software maintenance tasks to be done during normal business hours,
	limits the downtime required to the time it takes to reboot the system, and enables use of both
	proactive and reactive patching.
fileset	A grouping of one or more files contained in a product or subproduct. A fileset groups a subset
	of a product's files into a manageable unit. Most Software Distributor operations are performed
	on filesets.
