10. CMISE Services M-GET: invoked by a CMISE-service-user to request the retrieval of management information from a peer CMISE-service-user M-GET: invoked by a CMISE-service-user to request the retrieval of management information from a peer CMISE-service-user M-SET: invoked by a CMISE-service-user to request the modification of management information by a peer CMISE-service-user M-SET: invoked by a CMISE-service-user to request the modification of management information by a peer CMISE-service-user M-CANCEL-GET: invoked by a CMISE-service user to request a peer CMISE-service-user to cancel a previously requested and currently outstanding invocation of the M-GET service M-CANCEL-GET: invoked by a CMISE-service user to request a peer CMISE-service-user to cancel a previously requested and currently outstanding invocation of the M-GET service

11. M-CREATE: invoked by a CMISE-service-user to create an instance of a managed object M-CREATE: invoked by a CMISE-service-user to create an instance of a managed object M-DELETE: invoked by a CMISE-service-user to request a peer CMISE-service-user to delete an instance of a managed object M-DELETE: invoked by a CMISE-service-user to request a peer CMISE-service-user to delete an instance of a managed object M-ACTION: invoked by a CMISE-service-user to request a peer CMISE-service-user to perform an action M-ACTION: invoked by a CMISE-service-user to request a peer CMISE-service-user to perform an action M-EVENT-REPORT: invoked by a CMISE-service- user to report an event about a managed object to a peer CMISE-service-user M-EVENT-REPORT: invoked by a CMISE-service- user to report an event about a managed object to a peer CMISE-service-user CMISE Services

13. Three Trees in OSI Management n Registration Tree n Containment Tree n Inheritance Tree

14. Containment Tree root

15. Managed Object Selection - Scoping : identify the managed object(s) which a filter is to be applied. - Filtering : apply a set of tests to each member of the set of previously scoped managed objects to extract a subset.

16. Scoping the base object alone the base object alone the nth level subordinates of the base object the nth level subordinates of the base object the base object and all its subordinates down to and including the nth level the base object and all its subordinates down to and including the nth level the base object and all of its subordinates (whole substree) the base object and all of its subordinates (whole substree) 1th level base object

17. Filtering and Synchronization - Filtering - A filter is a set of one or more assertions about the presence or values of attributes in a scoped MO. If the filter test succeeds for a given managed object, then that managed object is selected for performance of the operation. - Synchronization -A synchronization parameter is provided to allow the CMISE-service-user to indicate the manner in which operations are to be synchronized across managed object instances when multiple MOs have been selected by the scope and filter mechanism. -Best efforts & atomic

18. Association Services Services Type A-ASSOCIATEConfirmed A-RELEASE Confirmed A-ABORT Non-confirmed A-P-ABORT Provider-initiated

19. Association Services A-ASSOCIATE Causes the establishment of an association A-RELEASE Causes the release of an association A-ABORT Causes the abnormal release of the association with the possible loss of information in transit A-P-ABORT Indicates the abnormal release of the association as a result of action by the underlying services

21. Invoke Identifier and Linked Identifier Invoke Identifier: specifies the identifier of the operation. It can be used to distinguish this operation from other notification or operations that the CMISE-service- provider may have in progress. Each response shall have a unique invoke identifier; the final response shall have an invoke identifier equal to that of the invoke identifier provided in the indication primitive. Linked Identifier: When multiple replies are to be sent, it shall have the same value as that of the invoke identifier provided in the indication primitive. The completion of the response is indicated by the performing CMISE-service-user issuing an M-GET response primitive which shall not contain the linked identifier, and, if there were linked responses generated, which shall not contain the attribute list.
