ISO/IEC 9805-1:1998

Information technology — Open Systems Interconnection — Protocol for the Commitment, Concurrency and Recovery service element: Protocol specification — Part 1:

This Recommendation | International Standard is to be applied by reference from other specifications. This is done within such specifications by reference to the CCR services defined in ITU-T Rec. X.851 | ISO/IEC 9804. A reference to a CCR service invokes the procedures of this Recommendation | International Standard to cause external effects. This Recommendation | International Standard specifies, in clause 9, a use of the ACSE, Presentation and Session services to carry the CCR semantics. This "reference" mapping can be used whenever the use of these services does not conflict with the user made by other ASEs or ASOs that are using the same association. Annex B defines how a different use of supporting services may be specified, for use where the reference mapping is inappropriate. This Recommendation | International Standard specifies the static and dynamic conformance requirements for systems implementing these procedures. It does not contain tests which can be used to demonstrate conformance. This edition of this Recommendation | International Standard specifies CCR protocol Version 2, which makes use of the Session Data Separation functional unit to protect data not belonging to the CCR atomic action. The 1990 edition of ISO/IEC 9805 specified CCR protocol Version 1. The 1993/1994 edition of this Recommendation | International Standard specified both CCR protocol Version 1 and CCR protocol Version 2, for the static commitment functional unit only. This International Standard specifies the protocol elements that support the following functional units: a) static commitment; b) dynamic commitment; c) read only; d) one-phase commitment; e) cancel; and f) overlapped recovery.

Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form
the specialized system for worldwide standardization. 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 9805-1 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information
technology, Subcommittee SC 33, Distributed application services, in collaboration with ITU-T. The identical text is
published as ITU-T Recommendation X.852.
This third edition cancels and replaces the second edition (ISO/IEC 9805-1:1994), which has been technically revised.
ISO/IEC 9805 consists of the following parts, under the general title Information technology — Open Systems
Interconnection — Protocol for the Commitment, Concurrency and Recovery service element:
— Part 1: Protocol specification
— Part 2: Protocol Implementation Conformance Statement (PICS) proforma
Annexes A and B form an integral part of this part of ISO/IEC 9805.

This Recommendation | International Standard is one of a set of Recommendations | International Standards produced to
facilitate the interconnection of information processing systems. It is related to other Recommendation | International
Standards in the set as defined by the Reference Model for Open Systems Interconnection (see ITU-T Rec. X.200 |
ISO/IEC 7498-1). The Reference Model subdivides the area of standardization for interconnection into a series of layers
of specification, each of manageable size.
The goal of Open Systems Interconnection is to allow, with a minimum of technical agreement outside the
interconnection standards, the interconnection of information processing systems:
– from different manufacturers;
– under different managements;
– of different levels of complexity; and
– of different technologies.
This Recommendation | International Standard specifies the protocol for the application-service-element for
Commitment, Concurrency, and Recovery (CCR). These services are intended to be applicable to a wide range of
application-process communication requirements.
This Recommendation | International Standard specifies CCR Protocol Version 2. The 1990 edition of ISO/IEC 9805
specified CCR protocol Version 1. The 1993/1994 editions of this Recommendation | International Standard specified
both CCR protocol Version 1 and CCR protocol Version 2, for the static commitment functional unit only.
The CCR protocol specification consists of the following main components:
a) the specification of the CCR APDUs using Abstract Syntax One (ASN.1, ITU-T Rec. X.680 |
ISO/IEC 8824-1);
b) the elements of procedure for issuing CCR service indication and confirm primitives to the CCR
service-user when CCR APDUs are received and for the sending of CCR APDUs when CCR service
request and indication primitives are received from the CCR service-user;
c) the CCR protocol machine specified in terms of a state table; and
d) the presentation services (see ITU-T Rec. X.216 | ISO/IEC 8822) used for sending and receiving CCR
APDUs.
The CCR protocol shares the presentation-service with other application-service-elements.
The requirement to provide support for CCR together with other application-service-elements is satisfied by reference to
this Recommendation | International Standard.
Annex A contains the definitions of the structure of the CCR APDUs.
Annex B describes how the CCR can be used in combination with other ASEs that use the presentation service in a way
that is not compatible with the use of the presentation service by CCR as specified in the body of this Recommendation |
International Standard.

This Recommendation | International Standard is to be applied by reference from other specifications. This is done
within such specifications by reference to the CCR services defined in ITU-T Rec. X.851 | ISO/IEC 9804. A reference to
a CCR service invokes the procedures of this Recommendation | International Standard to cause external effects.
This Recommendation | International Standard specifies, in clause 9, a use of the ACSE, Presentation and Session
services to carry the CCR semantics. This “reference” mapping can be used whenever the use of these services does not
conflict with the user made by other ASEs or ASOs that are using the same association. Annex B defines how a different
use of supporting services may be specified, for use where the reference mapping is inappropriate.
This Recommendation | International Standard specifies the static and dynamic conformance requirements for systems
implementing these procedures. It does not contain tests which can be used to demonstrate conformance.
This edition of this Recommendation | International Standard specifies CCR protocol Version 2, which makes use of the
Session Data Separation functional unit to protect data not belonging to the CCR atomic action. The 1990 edition of
ISO/IEC 9805 specified CCR protocol Version 1. The 1993/1994 edition of this Recommendation | International
Standard specified both CCR protocol Version 1 and CCR protocol Version 2, for the static commitment functional unit
only.
This International Standard specifies the protocol elements that support the following functional units:
a) static commitment;
b) dynamic commitment;
c) read only;
d) one-phase commitment;
e) cancel; and
f) overlapped recovery.

Avant-propos
L ’ISO (Organisation internationale de normalisation) et la CE1 (Commission electrotechnique internationale) forment
ensemble un Systeme consacre a la normalisation internationale consideree comme un tout. Les organismes nationaux
membres de HS0 ou de la CE1 participent au developpement de Normes internationales par l ’intermediaire des comites
techniques cr& par l ’organisation concernee afin de s ’occuper des differents domaines particuliers de l ’activite technique. Les
comites techniques de I ’ISO et de la CE1 collaborent dans des domaines d ’interet commun. D ’autres organisations
internationales, gouvernementales et non gouvernementales, en liaison avec 1 ’ISO et la CE1 participent egalement aux travaux.
Dans le domaine des technologies de l ’information, I ’ISO et la CE1 ont cree un comite technique mixte, l ’ISO/CEI JTC 1. Les
projets de Normes internationales adoptes par le comite technique mixte sont soumis aux organismes nationaux pour
approbation, avant leur acceptation comme Normes internationales. Les Normes internationales sont approuvees
conformement aux procedures qui requierent l ’approbation de 75 % au moins des organismes nationaux votants.
La Norme internationale ISO/CEI 9805-1 a etc elaboree par le comite technique mixte ISOKEI JTC 1, Technologies de
Z ’information, sous-comite SC 33, Services d ’applications distribukes, en collaboration avec I ’UIT-T. Le texte identique est
publik en tant que Recommandation UIT-T X.852.
Cette troisieme edition annule et remplace la deuxieme edition (ISOKEI 98051: 1994), qui a fait l ’objet d ’une revision
technique.
L ’ISOKEI 9805 comprend les Parties suivantes, presentees sous le titre general Technologies de Z ’information -

Introduction
La presente Recommandation 1 Norme internationale fait Partie d ’un ensemble de Recommandations j Normes
internationales elaborees pour faciliter l ’interconnexion des systemes de traitement de l ’information. Elle fait Partie d ’un
ensemble de Recommandations 1 Normes internationales dont les relations sont definies par le modele de reference pour
l ’interconnexion des systemes ouverts (Rec. UIT-T X.200 / ISO/CEI 7498-1). Le modele de reference subdivise le
domaine de la normalisation pour l ’interconnexion en une Serie de Couches de specification, chacune de taille maitrisable.
L ’objectif de 1 ’OSI est de permettre, avec un minimum d ’accords techniques en dehors des normes d ’interconnexion,
l ’interconnexion de systemes de traitement de l ’information:
-
provenant de divers fabricants;
-
geres differemment;
-
de niveaux de complexite differents;
-
de techniques differentes.
La presente Recommandation 1 Norme internationale specifie le protocole pour l ’element de Service d ’application (ASE,
application Service element) pour l ’engagement, la concomitance et le retablissement (protocole CCR). 11 est prevu que
ces Services s ’appliquent a une large gamme de besoins de communication entre processus d ’application.
La presente Recommandation 1 Norme internationale specifie la version 2 du protocole CCR. L ’edition de 1990 de
1 ’1SOKEI 9805 specifiait la version 1 du protocole CCR. L ’edition de 1993/1994 de la presente Recommandation
1
Norme internationale specifiait a la fois la version 1 et la version 2 du protocole CCR, uniquement pour l ’unite
fonctionnelle d ’engagement statique.
La specification du protocole CCR est composee des principaux elements suivants:
a) la specification des unites APDU du protocole CCR en utilisant la notation de syntaxe abstraite numero
un (ASN.l, definie dans la Rec. UIT-T X.680 1 ISOKEI 8824-1);
b) les elements de procedure d ’emission de primitives d ’indication et de confirmation de Service CCR, a
l ’intention de l ’utilisateur de Service CCR, apres la reception d ’unites APDU du protocole CCR; les
elements de procedure d ’envoi d ’unites APDU du protocole CCR par l ’utilisateur de Service CCR, apres la
reception de primitives de demande et d ’indication de Service CCR;
la machine protocole CCR specifiee en termes de tables d ’etats;
4
d) les Services de presentation (voir la Rec. UIT-T X.216 1 ISOKEI 8822) utilises pour l ’emission et la
reception d ’unites APDU du protocole CCR.
Le protocole CCR partage le Service de presentation avec d ’autres elements de Service de la couche Application.
Lorsqu ’il est necessaire de foumir un support
du protocole CCR avec d ’autres elements de Service d ’application, il suffit
de faire reference a la presente Recommandati 1 Norme internationale.
on
L ’Annexe A definit la structure des unites APDU du protocole CCR.
L ’Annexe B decrit comment le protocole CCR peut etre utilise de facon combinee avec d ’autres ASE utilisant le Service
de presentation d ’une facon non compatible avec l ’utilisation, specifiee dans la presente Recommandation 1 Norme
internationale, que fait le protocole CCR de ce meme Service.

NORME INTERNATIONALE
RECOMMANDATION UIT-T
TECHNOLOGIES DE L ’INFORMATION - INTERCONNEXION DE SYSTEMES
OUVERTS (OSI) - PROTOCOLE POUR L ’I?LkMENT DE SERVICE D ’ENGAGEMENT,
DE CONCOMITANCE ET DE RETABLISSEMENT: SPIkIFICATION DU PROTOCOLE
1 Domaine d ’application
La presente Recommandation 1 Norme internationale doit etre appliquee en y faisant reference dans d ’autres
specifications. Ces specifkations font reference aux Services CCR definis dans la Rec. UIT-T X.851 1 ISO/CEI 9804.
Une reference a un Service CCR invoque les procedures definies dans la presente Recommandation 1 Norme
internationale et entraine des effets externes.
La presente Recommandation 1 Norme internationale specifie, dans l ’article 9, une utilisation de l ’element de Service
ACSE, des Services de presentation et de Session pour transporter la semantique du protocole CCR. Ce mappage “de
reference” peut etre utilise chaque fois que l ’utilisation de ces Services n ’est pas en conflit avec l ’utilisation faite par
d ’autres ASE et AS0 qui utilisent la meme association. L ’Annexe B definit la facon de specifier une utilisation
differente des Services supports lorsque l ’utilisation du mappage de reference n ’est pas appropriee.
La presente Recommandation 1 Norme international e specifie les conditions de conformite statique et dynamique des
systemes qui mettent en ceuvre ces procedures. Elle ne contient pas les tests qui peuvent etre utilises pour demontrer la
conformite a ces conditions.
L ’edition de la presente Recommandation 1 Norme internationale specifie les Versions de protocole suivantes:
La version 2 du protocole CCR, qui fait appel a l ’unite fonctionnelle de Separation des donnees de Session afin de
proteger des donnees ne dependant pas de l ’action atomique du protocole CCR. L ’edition de 1990 de l ’ISO/CEI 9805
specifiait la version 1 du protocole CCR. L ’edition de 1993/1994 de la presente Recommandation 1 Norme internationale
specifiait a la fois la version 1 et la version 2 du protocole CCR, uniquement pour l ’unite fonctionnelle d ’engagement
statique.
La presente Norme internationale specifie les elements de protocole supportant les unites fonctionnelles suivantes:
engagement statique;
a>
b) engagement dynamique;
c) lecture seule;
d) engagement en une Phase;
annulation;
e>
retablissement recouvert.
