Who Uses HP WBEM Services?
Providers use HP WBEM Services to help their users manage
particular things about their resource.
Clients use HP WBEM Services to manage resources. Following
information in provider documentation, developers write a software
client to send requests to HP WBEM Services.
HP WBEM Services conveys the request to the appropriate registered
provider. The providers send information back to HP WBEM Services.
HP WBEM Services sends that information back to the client in a
response. One response is sent for each request, even when the
information comes from several providers.
See Appendix A for some of the common terms and concepts used by
providers to represent resources.
HP WBEM Services Providers
To manage a resource, a developer writes software called a CIM provider.
When you install a provider on your system, it registers itself with HP
WBEM Services.
When a Provider Installs
When a provider registers with HP WBEM Services, it supplies this
information:
• The definition of the resource. See Appendix A, How Resources are
Represented.
Resources are defined largely by characteristics inherited from the
most general classes and passed to the more specific subclasses. For
example, there could be a schema, Creature, that contained a class
Human. Human could, in turn, have a subclass Female. Class
Female could, in turn, have several more subclasses until we get to
the specific instance of MyMother.
Resources can also be grouped in namespaces. HP WBEM Services
installs with four namespaces, listed in Appendix A.
• What information the resource provider will expose (make available)
about the resource. These are the properties and methods.
