Foreword
IS0 (the International Organization for Standardization) ancl IEC (the
International Electrotechnical Commission) form 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 com-
mittees collaborate in fields of mutual interest Other international or-
ganizations, 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, ISWEC JTC 1. Draft International Siandards
adopted by the joint technical committee are circulated to national bod-
ies for voting. Publication as an International Standard requires ap-
proval by at least 75 % of the national bodies casting a vote.
International Standard ISO/IEC 8831 was prepared by Joint Technical
Committee ISO/IEC JTC 1, lnformation technology.
This second edition cancels and replaces the first edition
(IS0 8831:1989). The text of this second edition of ISO/IEC 8831 includes
changes resulting from alignment with ISO/IEC 9804 (CCR) and the full
protocol amendment to ISO/IEC 8832.
Annexes A and B form an integral part of this International Standard
Annexes C and D are for information only.

Introduction
The purpose of the job transfer and manipulation (JTM) standard is to provide a set of
communication-related services which can be used to perform work in a network of in-
~
terconnected open systems. This work can include both the running of traditional back-
ground jobs and other forms of information processing.
Background jobs have, in the past, been submitted either directly on the host system
where they ran, or else at a remote job entry station connected to that system. Data
files, program and "JCL" would be already available on the host, or would form part of
the submitted "job deck. Output would be delivered on the host system, or alternative-
ly on a printer aîiached to the remote job entry station. In a network of open systems,
such jobs can be submitted at any open system supporting JTM to be run on another
open system, using files collected from any other open systems, with output directed to
peripherals or files held on any other open systems.
The JTM protocol covers not only the movement of job-related data (input and output)
between open systems, but also provides for the movement of data concerned with
monitoring job-related activity, and for controlling and manipulating the progress of this
activity.
This International Standard does not specify individual implementations or products, nor
does it constrain the implementation of entities and interfaces within a computer sys-
tem. There is, therefore, no conformance to this International Standard.
Annex A is part of this International Standard, and describes the notation used for JTM
service definition. This differs from that used by lower layers of OS1 only because JTM
is concerned with concurrent and related activity on more than two open systems. It is
a superset of the notation used in the lower layers.
Annex B is part of this International Standard, and defines the requirements of JTM for
a Document Type Registration Authority. These requirements of JTM apply to private,
enterprise-specific, Registration Authorities; they are, however, also expected to be sat-
isfied by any International Standard covering this area.
Annex C is tutorial material, and is not part of this International Standard. It gives a broad
introduction to JTM, and should be read first by readers unfamiliar with the JTM work.
Annex D is not part of this International Standard, and contains an alphabetic glossary
of the definitions appearing in the body of this International Standard.

INTERNATIONAL STANDARD ISO/IEC 8831:1992(E)
Information technology - Open Systems Interconnection -
Job transfer and manipulation concepts and services
Section 1 : General
1.1 Scope
This International Standard is an application layer standard within the Open Systems Interconnection framework set up by IS0
7498.
It defines the concepts and services for job transfer and manipulation.
This International Standard requires that the user of JTM
- specifies the open systems where work is to be done;
- knows the local functions and facilities of the open systems where work is to be done;
- knows the control languages used to specify local work on the open systems where work is to be done.
This International Standard provides the means to
- to specify work to be done on one or more open systems. The work done at one open system can result in new work
to be done at other open systems;
- monitor the execution of work previously specified;
- modify work previously specified.
This International Standard does not address the standardisation of control languages, but is also applicable to the use of a
standardised control language. This International Standard does not address the standardisation of user interfaces.
1.2 Normative references

1.3 Definitions
1.3.1 CCR service definitions
This International Standard makes use of the following terms defined in ISO/IEC 9804:
a) atomic action
b) master
c) superior
d) subordinate
e) commitment
f) rollback
1.3.2 JTM service definitions
The definitians are grouped into major categories, corresponding to the subclauses of clause 2.1.
For the purposes of this International Standard, the following definitions apply.
1.3.2.1 General
1.3.2.1.1 agency: An abstract description of those functions of a real open system which are needed to support the JTM
service.

the work which is to be done.
A collection of data which forms part of a work specification, and which forms a unit of interaction
1.3.2.1.3 hcument:
between the JTM service provider and an agency.
That agency which causes a work specification to be created.
1.3.2.1.4 initiation agency:
1.3.2.2 Pmiiformas and spawning
1.3.2.2.1 proforma: Part of a work specification which specifies further work and is used to form a new work specification
as part of the processing of earlier work.

---------------------- Page: 10 ----------------------
ISOllEC 8831:1992(E)
1.3.2.2.2 spawning: The process of taking the data from a proforma and using it to produce a new work specification.
1.3.2.2.3 spawning control data: Data contained in a proforma which controls the circumstances in which spawning takes
place from that proforma.
1.3.2.2.4 top level proforma:
A proforma which is not contained within any other proforma.
NOTE - A proforma which is not a top-level proforma can become a top-level proforma as a result of spawning from its parent.
1.3.2.3
Source, sink and execution agencies
1.3.2.3.1 source agency: Any part of an open system which can provide documents for inclusion in a work specification
when required by the JTM service provider as a result of processing the work specification.
1.3.2.3.2 sink agency:
Any part of an open system to which documents can be passed by the JTM service provider as a
result of processing a work specification.
NOTE - Source and sink agencies can obtain and dispose of documents locally, or by use of non-standard protocols, or by use of FTAM.
1.3.2.3.3 execution agency: Any part of an open system which initially acts as a sink for documents, but which subsequently
acts as a source of related documents produced as a result of processing the earlier documents.
1.3.2.3.4 activity (in an agency): Work performed by an agency, initiated by a service primitive issued to the agency by
the JTM service provider; the completion of the activity is indicated by a service primitive issued to the JTM service provider by
the agency.
1.3.2.4 OS1 jobs
1.3.2.4.1 initial work specification: A work specification created as a result of the issue of an initiation service primitive by
an initiation agency.
1.3.2.4.2 OS1 job: The total work on all open systems arising directly or indirectly from an initial work specification.
1.3.2.4.3 OS1 subjob (subjob): The total work arising from the processing of a single work specification, including the
spawning of further work specifications, but excluding work arising from the processing of these further work specifications.
1.3.2.4.4 OS1 job submission: The use of the initiation service primitive by an initiation agency for the creation of an initial
work specification.
1.3.2.4.5 OS1 job submission system: The open system on which OS1 job submission occurs.
1.3.2.5 Reporting and the monitor function

1.3.2.5.3 report work specification: The type of work specification created by the JTM service provider to move JTM re-
ports; the target open system for these work specifications is one of the OS1 job monitors.
1.3.2.6 Commitment, concurrency and recovery
1.3.2.6.1 level of commitment: A parameter which determines whether operations requested in an atomic action are com-
pleted at the time of the atomic action, or are noted (as secure data) for later performance.
1.3.2.6.2 warning diagnostic: Information carried by the CCR service on an offer of commitment which reports (usually for
a human being) any variations on the expected action or unexpected consequences of the action.
1.3.2.6.3 retry-later diagnostic: Information carried by the CCR service on a rollback when an action cannot be completed
for reasons which can be transient.
1.3.2.6.4 no-retry diagnostic: Information carried by the CCR service on a rollback when an action cannot be completed,
and a later retry is not proposed.
