National bodies that are members of ISO 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. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC 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 13650-2 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 21, Open systems interconnection, data management and open distributed processing. ISO/IEC 13650 consists of the following parts, under the general title Information technology Open Systems Interconnection Conformance test suite for the OSI TP protocol: Part 1: Test suite structure and test purposes; Part 2: Test management protocol specification. Annex A and Annex B of this part of ISO/IEC 13650 are for information only. Licensed Copy: sheffieldun sheffieldun, na, Wed Nov 22 07:26:01 GMT+00:00 2006, Uncontrolled Copy, (c) BSI BS ISO/IEC 13650-2:1997 © BSI 09-19991 Introduction ISO/IEC 10026, Distributed Transaction Processing (OSI TP), is one of a set of standards produced to facilitate the interconnection of computer systems. It is related to other International Standards in the set as defined by the Basic Reference Model for Open Systems Interconnection (ISO/IEC 7498-1). The Basic Reference Model subdivides the area of standardization for interconnection into a series of layers of specification, each of manageable size. In order to ensure that implementations of ISO/IEC 10026-3 are conformant, testing standards have been defined using the methodology described in ISO/IEC 9646. The Coordinated test method has been chosen for the Abstract Test Suite. This particular test method requires the use of a Test Management Protocol, and this part of ISO/IEC 13650 defines the protocol. 1 Scope This part of ISO/IEC 13650 provides: A specification of a Test Management Protocol for use in conformance testing of Distributed Transaction Processing systems when the Coordinated Test Method of ISO/IEC 9646 is employed. This Test Management Protocol does not rely on any specified Application Programming Interface (API) within the System Under Test, but rather assumes the existence of a mapping from the abstract service primitives issued by the upper tester to the functionality of the implementation under test realizing ISO/IEC 10026-3. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of ISO/IEC 13650.

At any particular time, one unique lower tester shall be responsible for the transfer of TMP. This part of ISO/IEC 13650 defines the format the PDUs sent between this specific lower tester and upper tester, and the log records sent from the upper tester to the lower tester during a TP test campaign. Information is exchanged between one of the lower testers and the upper tester in the form of TMPDUs. The TMPDUs are carried as parameters of U-ASE APDUs on TP dialogues. There are five TMPDUs which may be sent during a test case, namely: TM-TEST-PROCEDURE
