X.863 (1994 E) ITU-T RECMN4cX.863 94 W 4862591 0597748 276 Introduction This Recommendation I Intemational Standard for OS1 Distributed Transaction Processing (TP) is one of a set of Recommendations I International Standards produced to facilitate the interconnection of comput

20、er systems. It is related to other CCITT Recommendations I International Standards in the set as defined by the Reference Model for Open Systems Interconnection (ITU-T Rec. X.200 I IS0 7498-1). The Reference Mode1 subdivides the area of standardization for interconnection into a series of layers of

21、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: a) from different manufacturers; b) under different management; c) d) of different techno

22、logies. of different levels of complexity; and, The Recommendations I International Standard for OS1 TP define a TP Model, a TP Service and specify a TP communications Protocol available within the Application Layer of the OS1 Reference Model. The TP Service is of the category defined in the Applica

23、tion Layer Structure standard. It is concerned with identifiable information which can be related as transactions, which may involve two or more open systems. The Recommendations I International Standard for OS1 TF defines a basic TP Service. It provides sufficient facilities to support transaction

24、processing, and establishes a framework for coordination across multiple TP resources in separate Open Systems. The Recommendations I International Standard for OS1 TP does not specify the interface to local resources or access facilities that are provided within the local system. However detailed c

25、onsideration of access to the local resources and their management may lead to some enhancement in a future revision of the Recommendations I International Standard. To evaluate conformance of a particular implementation, it is necessary to have a statement of which capabilities and options have bee

26、n implemented for a given OS1 protocol. Such a statement is called a Protocol Implementation Conformance Statement (PICS). The PICS Proforma, Annex A, has been designed to be a self contained section of this Recommendation I Part of ISO/IEC 1026 for use in testing and procurement. ITU-T Rec. X.863 (

28、ndation I International Standard provides the PICS proforma for the Distributed Transaction Processing protocol as specified in ITU-T Rec. X.862 I ISOAEC 10026-3 in compliance with the relevant requirements, and in accordance with the relevant guidance, given in CCITT Rec. X.291 I ISO/IEC 9646-2. De

29、tails of the use of this proforma is provided in this Recommendation I Part of ISOAEC 10026. Implementors of implementations claiming conformance to ITU-T Rec. X.862 I ISO/IEC 10026-3 shall complete the proforma as part of the conformance requirements. The level of detail required in the proforma ex

30、ceeds that of the protocol specification by requiring details to uniquely identify the implementation and the supplier. NOTE - PICS are related to base standards and only base standards. PICS Proforma structure might be expanded and refined for other documents (e.g. ISPs) using the base standards (e

31、.g. ISPICS Proforma). 2 Normative references The following Recommendations and International Standards contain provisions which, through reference in this text, constitute provisions of this Recommendation I International Standard. At the time of publication, the editions indicated were valid. All R

32、ecommendations and Standards are subject to revision, and parties to agreements based on this Recommendation I International Standard are encouraged to investigate the possibility of applying the most recent editions of the Recommendations and Standards listed below.
