34、n) form the specialized system for worldwide standardization. National bodies that are members of IS0 or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. IS0 and
35、 IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with IS0 and IEC, also take part in the work. In the field of information technology, IS0 and IEC have established a joint technical committee, ISO/IEC
36、 JTC 1. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote. International Standard ISO/IEC 10026-2 was prepared by Joint
37、 Technical Committee ISO/IEC JTC 1, lnformation fechnology, Subcommittee SC 21, Open systems interconnection, data management and open distributed processing. This third edition cancels and replaces the second edition (ISO/IEC 10026-2:1996), which has been technically revised. This part of ISO/IEC 1
38、0026 is technically aligned with ITU-T Recommendation X.861, but is not published as identical text. ISO/IEC 10026 consists of the following parts, under the general title Information technology - Open Systems Interconnection - Distributed Transaction Processing. - Part 1: OSI TP Model - Part 2: OSI
39、 TP Service - Part 3: Protocol specification - Part 4: Protocol Implementation Conformance Statement (PICS) proforma - Part 5: Application context proforma and guidelines when using 0.9 TP - Part 6: Unstructured Data Transfer Annex A forms an integral part of this part of ISO/IEC 10026.

It is related to other International Standards in the set as defined by the Reference Model for Open Systems Interconnection
41、(lSO/lEC 7498-l). The Reference Model subdivides the area of standardization for interconnection into a series of layers of specification, each of manageable size. The aim of Open Systems Interconnection is to allow, with a minimum of technical agreement outside the interconnection standards, the in
42、terconnection of computer systems 4 b) c) 4 from different manufacturers; under different management; of different levels of complexity; and of different technologies. ISO/IEC 10026 defines an OSI TP Model, an OSI TP Service and specifies an OSI TP Protocol available within the Application Layer of
43、the OSI Reference Model. The OSI TP Service is an Application Layer service. It is concerned with information which can be related as distributed transactions, which involve two or more open systems. This part of ISO/IEC 10026 defines a basic OSI TP Service. It provides sufficient facilities to supp
44、ort transaction processing, and establishes a framework for coordination across multiple TP resources in separate open systems. ISO/IEC 10026 does not specify the interface to local resources or access facilities that are provided within the local system. However, future enhancement of the standard
45、may deal with these issues. vi INTERNATIONAL STANDARD 0 ISO/IEC lSO/lEC 10026-2:1998(E) Information technology - Open Systems Interconnection - Distributed Transaction Processing - Part 2: OSI TP Service 1 Scope This part of ISO/IEC 10026 defines in an abstract way the Distributed Transaction Proces
46、sing Service within the Application Layer in terms of: a) the actions and events of the service primitives; b) the parameter data associated with each service primitives action and event; and c) the relationship between, and the valid sequences of these actions and events. It does not specify indivi
47、dual implementations or products, nor does it constrain the implementation of entities or interfaces within a computer system. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of ISO/IEC 10026.
