17、 ISO/IEC 10164-6 : 1993 (E) INTERNATIONAL STANDARD CC RECOMMENDATION INFORMATION TECHNOLOGY - OPEN SYSTEMS INTERCONNECTION - SYSTEMS MANAGEMENT: LOG CONTROL FUNCTION 1 Scope This Recommendation I International Standard defines a Systems Management Function which may be used by an application process
18、 in a centraiized or decentraiized management environment to interact for the purpose of systems management, as defined by CCITT Rec. X.700 I IS/IEC 7498-4. This CCT Recommendation I International Standard defines the Log Control function and consists of services and two functional units. This funct
19、ion is positioned in the application layer of the CCITT Rec. X.200 I ISO/IEC 7498-1 and is defined according to the model provided by ISO/IEC 9545. The role of systems management functions is described by CCITT Rec. X.701 I ISO/IEC 10040. This CC Recommendation I Intemationa Standard - - - establish
20、es user requirements for the Log Control function; establishes models that relate the services provided by the function to user requirements; defines the services provided by the function; - - - - specifies conformance requirements. specites the protocol that is necessary in order to provide the ser

22、ion; specify the manner in which management is accomplished by the user of the Log Control function; define the nature of any interactions which result in the use of the Log Control function; specifj the services necessary for the establishment, normal and abnormal release of a management aSsociati0
23、n; specify the authorization requirements for the use of the Log Control function or for any associated activity; define the definitions of managed objects related to the management of particular protocol machines. - - 2 Normative references The following CCITT Recommendations and Intemational Stand

46、gement functions it is necessary to be able to preserve information about events that may bave occurred or operations that may bave been performed by or on various objects. In a real open system various resources may be allocated to store such information. In OS1 management these resources are model
47、ed by logs and log records contained in the logs. The management needs for the type of information that is to be logged may change from time to time. Furthermore, when such information is retrieved hm a log the manager must be able to determine whether any mrds were lost or whether the characteristi
48、cs of the records stored in the log where modified at any time. 4 CC“ Rec.
