 9 karl  1.2 The Pegasus MSB interfaces with several different entities:

10 karl  1.1 
11           <UL> <LI> Providers

12 karl  1.2      <LI> Services (Including respositories and other services)

13 karl  1.1      <LI  Clients which may be either connectors or application consumers
14           </UL>
15           
16           Further, it includes both the APIs and the definitions of CIM data that are
17           required by the broker.
18           
19           Pegasus has effectivly implemented the same operations and data defintions across all of these interfaces with minor differences because of the special characteristics of each interface.

21           <B>Client Interface</B>
22           
23           
24           <B>Provider Interface</B>
25           
26           In Pegasus, the provider is a separate executable that accesses the
27           managed resources and is used by the CIMOM to provide access to
28           data. Providers forward this information to the CIMOM for
29           integration and interpretation. When the CIMOM receives a
30           request from a management application for data that is not available from the
31           CIMOM Repository, it forwards the request to a provider. The
32           CIMOM Repository only contains static data.
33           Providers implement a provider interface that supports the type of service
34           specific to their role. In order to implement the interface, a provider class
35           must first declare the interface in an implements clause, and then it must
36           provide an implementation (a body) for all of the abstract methods of
37           the.interface.

43           
44           <B>Repository Interface</B>
45           
46           The repository interface isused by the CIMOM to  interface with implementations of the repository thatstore and
47           retrieve provide persistence for class and instance information. 
48           
49           A prototype implementation of both a class and instance provider is provided with Pegasus (ATTN: SEE ALSO). However, it is expected that this will be replaced in many installations.
