Nationa
38、l 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 IEC technical committees collaborate in fields of mutual interest. O
39、ther 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 JTC 1. Draft International Standards adopted by the joint technical
40、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 Technical Committee ISO/IEC JTC 1, lnformation fechnology, Subcommit
41、tee 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 10026 is technically aligned with ITU-T Recommendation X.861, but is n
42、ot 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 TP Service - Part 3: Protocol specification - Part 4: Protocol Imple
43、mentation 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.

45、d to facilitate the interconnection of computer systems. It is related to other International Standards in the set as defined by the Reference Model for Open Systems Interconnection (lSO/lEC 7498-l). The Reference Model subdivides the area of standardization for interconnection into a series of laye
46、rs 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 interconnection of computer systems 4 b) c) 4 from different manufacturers; under different management; of different lev
47、els 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 the OSI Reference Model. The OSI TP Service is an Application Layer service. It is concerned with information which ca
48、n 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 support transaction processing, and establishes a framework for coordination across multiple TP resources in separate open
49、 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 may deal with these issues. vi Copyright American National Standards Institute Provided by IHS under license with ANSI Licensee=IHS Employees/1111111001, User=Wing, Bernie Not for Resale, 0
