Foreword
IS0 (the International Organization for Standardization) and IEC (the
International Electrotechnical Commission) for 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 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 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 ISOAEC 10026-2 was prepared by Joint Technical
Committee ISOAEC JTC 1, information technology, Subcommittee SC 21,
Open Systems Interconnection, data management and open distributed
processing.
This second edition cancels and replaces the first edition (ISO/IEC
10026-2:1992), which has been technically revised.
ISO/IEC 10026 consists of the following parts, under the general title

Introduction
ISO/IEC 10026 is one of a set of standards produced to facilitate the
It is related to other International
interconnection of computer systems.
Standards in the set as defined by the Reference Model for Open Systems
Interconnection (lSO/lEC 7498-1). 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
interconnection of computer systems
from different manufacturers;
a)
under different management;
b)
of different levels of complexity; and,
Cl
of different technologies.
d)
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 can be related as transactions, which may 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
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.

Part 2:
OSI TP Service
1 Scope
This part of ISO/IEC 10026 defines in an abstract way the Distributed Transaction Processing 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 primitive ’s action and event; and,
c) the relationship between, and the valid sequences of these actions and events.
It does not specify individual implementations or products, nor does it constrain the implementation of
entities or interfaces within a computer system.

3 Definitions
For the purposes of this part of ISO/IEC 10026, the definitions of ISO/IEC 10026-I and the following
definitions apply.
3.1 dialogue establishment indication outstanding: A dialogue state in which a TP-BEGIN-DIALOGUE
indication with the Confirmation parameter set to Vlalways” has been issued but has not yet been responded
to by a TP-BEGIN-DIALOGUE response.
A dialogue state in which a TP-BEGIN-DIALOGUE
3.2 dialogue establishment request outstanding:
request with the Confirmation parameter set to “alwaystl has been issued but has not yet been responded to
by a TP-BEGIN-DIALOGUE confirm.
A dialogue state in which a TP-END-DIALOGUE
3.3 dialogue termination indication outstanding:
indication with the Confirmation parameter set to Yrue” has been issued while there is no user error request
outstanding, but has not yet been responded to by a TP-END-DIALOGUE response, or by a TP-U-ERROR
request.
3.4 dialogue termination request outstanding: A dialogue state in which a TP-END-DIALOGUE request
with the Confirmation parameter set to Yrue” has been issued, but has not yet been responded to by a TP-
END-DIALOGUE confirm, or by a TP-U-ERROR indication-
3.5 handshake indication outstanding: A dialogue state in which one of the following service primitives:
- TP-HANDSHAKE indication;
- TP-HANDSHAKE-AND-GRANT-CONTROL indication;
has been issued while there is no user error request outstanding, but has not yet been responded to by one
of the following service primitives (respectively):
- TP-HANDSHAKE response;
- TP-HANDSHAKE-AND-GRANT-CONTROL response;
or by a TP-U-ERROR request, or, if the coordination level of the dialogue is %ommitmenY, by any rollback-
initiating service primitive.
3.6 handshake request outstanding: A dialogue state in which one of the following service primitives:
- TP-HANDSHAKE request;
- TP-HANDSHAKE-AND-GRANT-CONTROL request;
has been issued, but has not yet been responded to by one of the following service primitives (respectively):
- TP-HANDSHAKE confirm;
- TP-HANDSHAKE-AND-GRANT-CONTROL confirm;
or by a TP-U-ERROR indication, or, if the coordination level of the dialogue is ~~commitment~~, by any
rollback-initiating service primitive.
3.7 rollback-initiating indication: An indication or confirm that triggers a rollback; it is one of the
following service primitives:
- TP-ROLLBACK indication;
- TP-U-ABORT indication with the Rollback parameter set to “true ”;
- TP-P-ABORT indication with the Rollback parameter set to ‘Yruell;
- TP-BEGIN-DIALOGUE confirm with the Rollback parameter set to “true ”.

it is one of the following service
3.8 rollback-initiating request: A request that triggers a rollback;
primitives:
- TP-ROLLBACK request;
- TP-U-ABORT request for a dialogue with a coordination level of ttcommitmenttt not issued during the
termination phase of a transaction.
3.9 rollback-initiating service primitive: A service primitive that triggers a rollback; it may be either a
rollback-initiating request or a rollback-initiating indication.
3.10 subordinate dialogue: A dialogue with a subordinate.
3.11 subordinate subtree: A subtree of a subordinate.
3.12 superior dialogue: The dialogue with the superior.
3.13 termination phase of a transaction: The phase of a transaction between initiation of commitment or
rollback and the end of the transaction.
This phase is entered, for a given TPSUI, upon issuance of a TP-COMMIT request or any rollback-initiating
service primitive.
For a TPSUI which does not have a dialogue establishment indication outstanding, this phase is exited upon
issuance of a TP-COMMIT-COMPLETE indication or a TP-ROLLBACK-COMPLETE indication.
For a TPSUI which does have a dialogue establishment indication outstanding when the termination phase is
entered (this can only happen when a TP-ROLLBACK indication is issued), this phase is exited by a TP-
BEGIN-DIALOGUE response with the Result parameter set to Yejected(user)tt or by a TP-P-ABORT
indication for the dialogue; if the dialogue is accepted during the termination phase, the termination phase is
exited by the subsequent TP-ROLLBACK-COMPLETE indication.
3.14 transaction tree constraint: A constraint that cannot be checked at a single node.
3.15 user error indication outstanding: A state of a dialogue with the Polarized Control functional unit
selected. In this state, a TP-U-ERROR indication, issued while the recipient had control of the dialogue and
has neither a handshake request outstanding nor a dialogue termination request outstanding, has not yet
been responded to by a TP-GRANT-CONTROL request, or, if the coordination level of the dialogue is
“commitment ”, by any rollback-initiating service primitive.
3.16 user error request outstanding: A state of a dialogue with the Polarized Control functional unit
selected. In this state, a TP-U-ERROR request, issued without having control of the dialogue and without
having either a handshake indication outstanding or a dialogue termination indication outstanding, has not
yet been responded to by a TP-GRANT-CONTROL indication, a TP-HANDSHAKE indication, a TP-
HANDSHAKE-AND-GRANT-CONTROL indication, a TP-END-DIALOGUE indication with the Confirmation
parameter set to Yruett, or, if the coordination level of the dialogue is “commitmenY, by any rollback-initiating
service primitive.

5 Conventions
5.1 Service conventions
This part of ISO/IEC 10026 defines services for Distributed Transaction Processing guided by the descriptive
conventions defined in ISO/lEC 10731=
However, the terms Vequest” and Yndication” are sometimes used in the following ways:
a) a single request may result in multiple indications (an example is that a single VP-COMMIT request
may result in TP-PREPARE indications to each direct subordinate TPSUI);
b) several requests may result in a single indication (an example is that a single TP-COMMIT-
COMPLETE indication may be issued to a superior TPSUI only after TP-DONE requests have been
issued by this TPSUI and by all subordinate TPSUls in the transaction tree);
c) the convention that a request primitive results in an indication primitive of the same name, is not always
followed (for example, the issuance of a TP-COMMIT request will cause a TP-PREPARE indication to
be issued).
NOTE - In this part of ISOAEC 10026, requests and responses are described as being issued by the TPSUI
whereas indications and confirms are described as being issued by the TPSP.
For a given primitive, the presence of each parameter is described by one of the following values:
blank:
not applicable;
.
M .
presence. is mandatory;
.
U . presence is a user option;
.
0 . presence is a provider option; and,
.
C . presence is conditional.
In addition the notation (=) indicates that a parameter value is semantically equal to the value of the
parameter of the preceding primitive in the table.
5.2 Usage of the term transaction
In this part of ISO/IEC 10026, the term Yransaction” is used to denote a distributed provider-supported
transaction.
5.3 Usage of italics for notations
In this part of ISO/IEC 10026, the following notations, defined in clause 3, appear in italics:
- dialogue establishment indication outstanding;
- dialogue establishment request outstanding;
- dialogue termination indication outstanding;
- dialogue termination request outstanding;
- handshake indication outstanding;
- handshake request outstanding;
- rollback-initiating indication;
- rollback-initiating request;
