Announcement
The following information is for Version A.02.07 of HP WBEM Services.
HP WBEM Services for HP-UX is available from http://software.hp.com.
As the HP-UX implementation of the DMTF WBEM standard, the HP WBEM Services
product enables management solutions that deliver increased control of enterprise resources
at reduced cost. WBEM (Web-Based Enterprise Management) is a platform and
resource-independent DMTF (Distributed Management Task Force) standard that defines a
common information model and communication protocol for monitoring and controlling
resources from diverse sources.
WBEM is defined by the following standards:
• Common Information Model (CIM): CIM is an object-oriented information model for
describing managed resources. A CIM object is a representation of a managed resource.
CIM objects with similar properties and purposes are represented as CIM classes. A CIM
instance is a representation of a managed object that belongs to a particular class. CIM
objects can be shared by any WBEM-enabled system or applications. The definitions of
CIM classes are grouped into meaningful collections called schemas.
MOF (Managed Object Format) is the language for defining CIM classes and instances.
MOF files are ASCII files that use the MOF language to describe CIM objects.
• Representation of CIM in XML: XML (eXtensible Markup Language) is a markup
language for describing data on the web. The DMTF defines a standard for the
representation of CIM elements and messages in XML. Because CIM-XML provides a
standard way of describing data, any WBEM client can access CIM data on any
WBEM-enabled system.
• CIM Operations over HTTP: The CIM Operations over HTTP Specification defines the
way HTTP (HyperText Transfer Protocol) is used to transport the CIM information.
System Administrators benefit from the deployment of HP WBEM Services in the reduced
cost and greater choice in operating homogeneous and heterogeneous IT environments. HP
WBEM Services further supports HP’s efforts to deliver multi-platform, multi-operating
system management tools that leverage the existing training and knowledge base of today’s
IT staff, while positioning for heterogeneous environments that may be part of your IT plans.
In homogeneous environments, WBEM still offers the advantages of exposing management
information and capabilities in a standard way, regardless of architecture or platform specifics
(for example, PA-RISC and IPF).
