HP WBEM Services for HP-UX System Administrator Guide (5900-1624, April 2011)

E
extensible markup
language (XML)
A simplified subset of SGML that offers powerful and extensible data modeling capabilities. An
XML Document is a collection of data represented in XML. An XML Schema is a grammar that
describes the structure of an XML Document.
extension schema The third layer of the CIM schema, which includes platform-specific extensions of the CIM schema
such as Microsoft Windows NT, UNIX, and Microsoft ExchangeServer. Also see common model
and core model.
extrinsic method A method defined on a CIM Class in some Schema that is unique to that class (versus intrinsic
methods which apply across all classes). Also see intrinsic method.
H
HP WBEM
(Web-Based
Enterprise
Management)
An initiative based on a set of management and Internet standard technologies developed to
unify the management of enterprise computing environments. HP WBEM provides the ability for
the industry to deliver a well-integrated set of standard-based management tools leveraging the
emerging technologies such as CIM and XML.
HP WBEM Services A Hewlett-Packard product that uses WBEM to manage HP-UX system resources.
HTTP (Hypertext
Transfer Protocol)
An application-level protocol for distributed, collaborative, hypermedia information systems. It is
a generic stateless protocol that can be used for many tasks through extensions of its request
methods, error codes and headers.
HTTP Server HP WBEM Services uses a small-footprint special-services “light-weight” server that processes
HTTP requests and returns standard HTTP responses. The server is not intended as a replacement
for a web server. The server does not serve up HTML web pages and does not run CGI
applications.
I
indication An operation executed as a result of some action such as the creation, modification, or deletion
of an instance, access to an instance, or modification or access to a property. Indications can
also result from the passage of a specified period of time. An indication typically results in an
event.
inheritance The relationship that describes how classes and instances are derived from parent classes, or
superclasses. A class can spawn a new subclass, also called a child class. A subclass contains
all the methods and properties of its parent class.
Inheritance is one of the features that enables the CIM classes to function as templates for actual
managed objects in the CIM environment.
instance A representation of a real-world managed object that belongs to a particular class, or a particular
occurrence of an event. Instances contain actual data.
instance provider A type of provider that supports instances of system- and property-specific classes. Instances
providers can support data retrieval, modification, deletion, enumeration, or query processing.
Instance providers can also invoke methods Also see class provider and property provider.
intrinsic method A method defined for the purpose of modeling a CIM operation. Standard intrinsic methods (such
as enumerateInstances, getInstance, modifyInstance) are relevant to all classes. Also see extrinsic
method.
K
Kerberos A security mechanism that provides authentication, data integrity, data privacy, and mutual
authentication. (Available through PAM in HP-UX)
key A property that is used to provide a unique identifier for an instance of a class. Key properties
are marked with the Key qualifier. A compound key has more than one property, with a Key
qualifier.
key qualifier A qualifier that must be attached to every property in a class that serves as part of the key for
that class.
