This Recommendation | International Standard defines a systems management function which may be used by an application process in a centralized or decentralized management environment to interact for the purposes of systems management, as defined by CCITT Rec. X.700 | ISO/IEC 7498-4. This Recommendation | International Standard defines the object management function that consists of services, functional units, and generic definitions. It is positioned in the application layer of CCITT Rec. X.200 | ISO 7498 and is defined according to the model provided by ISO/IEC 9545. The role of systems management functions are described by CCITT Rec. X.701 | ISO/IEC 10040. This Recommendation | International Standard — establishes user requirements for the object management function; — establishes a model that relates the services and generic definitions provided by this function to user requirements; — defines the services provided by the function; — defines generic notification types and parameters documented in accordance with CCITT Rec. X.722 | ISO/IEC 10165-4; — specifies the protocol that is necessary in order to provide the services; — defines the relationship between these services and management operations and notifications; — specifies compliance requirements placed on other Standards that make use of these generic definitions; defines relationships with other systems management functions; — specifies conformance requirements. This Recommendation | International Standard does not — define the nature of any implementation intended to provide the object management function; — specify the manner in which management is accomplished by the user of the object management function; — define the nature of any interactions which result in the use of the object management function; — specify the services necessary for the establishment, normal and abnormal release of a management association; — preclude the definition of further notification types; — define managed objects.
