National bodies that are members of ISO or
14、IEC participate in thedevelopment of International Standards through technical committees established by the respective organization to dealwith particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest.Other international organizations, gover
15、nmental and non-governmental, in liaison with ISO and IEC, also take part in thework.In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. DraftInternational Standards adopted by the joint technical committee are circulated to national bodie
16、s for voting. Publicationas an International Standard requires approval by at least 75 % of the national bodies casting a vote.International Standard ISO/IEC 9804 was prepared by Joint Technical Committee ISO/IEC JTC 1, Informationtechnology, Subcommittee SC 33, Distributed application services, in
17、collaboration with ITU-T. The identical text ispublished as ITU-T Recommendation X.851.This third edition cancels and replaces the second edition (ISO/IEC 9804:1994), which has been technically revised.Annexes A and B form an integral part of this International Standard. Annex C is for information o
18、nly.v)NTRODUCTIONThis Recommendation | International Standard is one of a set of Recommendations | International Standards produced tofacilitate the interconnection of information processing systems. It relates to other ITU-T Recommendations |International Standards in the set defined by the Referen
19、ce Model for Open Systems Interconnection (see ITU-TRec. X.200 | ISO/IEC 7498). The reference model subdivides the area of standardization for interconnection into a seriesof layers of specification, each of manageable size.The goal of Open Systems Interconnection is to allow, with a minimum of tech
20、nical agreement outside theinterconnection Recommendations and International Standards, the interconnection of information processing systems: from different manufacturers; under different managements; of different levels of complexity; and of different technologies.This Recommendation | Internation
21、al Standard recognizes that application-processes may wish to communicate witheach other for a wide variety of reasons. However, any communication requires certain services independent of thereasons for communication. The application-service-element defined in this Recommendation | International Sta
22、ndardprovides such services.This Recommendation | International Standard defines the facilities of the application-service-element for Commitment,Concurrency and Recovery (CCR). CCR provides services for a single association. A referencing specification usesthese services for starting and ending a s
23、pecific sequence of distributed application operations despite application orcommunication failure.This Recommendation | International Standard is referenced by a specification to apply CCR to its operation. CCRservices may be used with presentation services (see ITU-T Rec. X.216 | ISO/IEC 8822), or
24、 with other ApplicationLayer services. However, the use of CCR services is subject to the restrictions specified in clause 9. The use of CCRservices allows a referencing specification to define its activity as an atomic action. An atomic action may use manyassociations, possibly with different proto
