EM-Club Newsletter Number 3, December 1993
Dear EM-Club members,
I wish you a Merry Christmas and a happy new year 1994.
Enclosed are some news and conference announcements about Enterprise Modelling and Enterprise Integration.
May I ask you to send me a selected list of your most significant publications in the field to be compiled in the next bulletin. Also, don't hesitate to pass me any piece of information that you would like to see distributed to EM-Club members.
Yours sincerely F. Vernadat
Item 1: EM-news: ----------------
1) Report on the IFIP/IFAC Task Force by P. Bernus and L. Nemes Joint IFAC/IFIP Task Force on Architectures for Integrating Manufacturing Activities and Enterprises =====================================================
In 1990 IFIP and IFAC set up the Task Force (TF) on Architectures for Integrating Manufacturing Activities and Enterprises with the aim of defining and evaluating Enterprise Reference Architectures.
The timeliness of this move was marked by the fact that by that time several groups around the world had been working on the definition of reference architectures and there was no way to compare or evaluate the results. These groups included private organisations/ sw/hw vendors, academic research institutions, and standards bodies.
In its first triennium the TF produced a major report (to be published in book form), a conference paper [1] (presented at the IFAC World Congress in Sydney, July 1993) and an article (to appear simultaneously in Computers in Industry - for IFIP, and Control Engineering Practice - for IFAC). By the time this message appears, the chairman Ted Williams will have presented the findings in a keynote address in Tokyo at the JSPE-IFIP WG 5.3 Workshop ``The Design of Information Infrastructure Systems for Manufacturing.''
Highlights of the study completed in the first triennium: --------------------------------------------------------
- The identification of TWO types of enterprise reference architectures, those which describe the structure of the control-/information system of the enterprise, and those which provide a life-cycle model of how to carry out enterprise integration.
- Detailed study of three important architectures of the latter type (CIM-OSA, GIM and Purdue Enterprise Refer- ence Architectures).
- Development of a matrix method by which it is possible to
- map concepts of one architecture to concepts of another and to
- identify the elements that a complete reference architecture must contain
- characterise the contribution of any architecture to a complete enterprise reference architecture.
- Recommendations for possible completion of available architectures either separately or by way of combining them into an encompassing Enterprise Reference Archi- tecture.
It is important that the TF identified: the studied architectures could complement one another rather then compete.
- Recommendations to carry out case studies which will uncover in more detail the strengths and weaknesses of the presently available architectures.
Future of the Task Force; -------------------------
The Task Force will continue its work as an IFAC Technical Committee (Architectures for Enterprise Integration) and possibly as a Working Group of IFIP TC5.
Liaisons with relevant other IFIP and IFAC groups, with ISO Technical Committees and other standards groups is deemed essential.
We are recruiting further members in view of extending the disciplinary base of the TF with the aim of keeping a balance of information technology (IS, SE), organizational and management, control engineering, economics, an socio- technical views.
The area of work for the next triennium continues to be Enterprise Reference Architectures of both types, the evaluation of case studies, further detailed work on the definition of a complete reference architecture, the relationship of enterprise reference architectures and architectures of more limited scope, and various modelling issues. The details of the action plan will be worked out in the next future.

2) DIISM'93 JSPE-IFIP WG 5.3 Working Conference on The Design of Information infrastructure Systems for Manufacturing, Tokyo, Japan, November 8-10, 1993 We have had an excellent meeting in Tokyo which attracted about 100 people. This was organised by Jan Goossenaerts and The University of Tokyo (as announced in the EM-Newsletter No. 2). Three days were dedicated to the paper presentations and one day was for industrial visits. Due to the novelty of the topic, some of the papers were outside of the scope of the discussions and the title of the Working Conference meant different things to different people. However, there were many papers on enterprise modelling, both on modelling technology and methodologies, and few on enterprise integration. Some papers dealt with Concurrent Engineering. The major trends demonstrated by this meeting were (1) the need for a common or generalized architecture for enterprise modelling, and (2) the move towards more formal enterprise models. Several papers addressed process models. Discussions on tools were also held. I think the meeting was enriching for everyone attending. Also, everyone could appreciate the friendly atmosphere and the good working ambiance of these four days. The structure of the Workshop encouraged technical discussions since there was one session at any time and enough time for paper presentation and discussions. The proceedings will be available from Elsevier in 1994. For more information, please contact Jan Goossenaerts at: jago@zzz.pe.u-tokyo.ac.jp

----------------------------------------------------------------------- SOME GENERAL REFERENCES FOR ADDITIONAL INFORMATION
"Distributed Object-based Programming Systems"(ACM Computing Surveys 3/91) by Roger Chin and Samuel Chanson
The general design and implementation issues of distributed object-based systems are discussed. Seven of the leading systems are analyzed based on these issues.
"An Overview of Projects on Distributed Systems" by Alfred Lupper (lupper@informatik.uni-ulm.de)
Ninety-eight distributed operating systems, environments, languages and microkernels are described.
"A Survey of Parallel Programming Languages and Tools"(Report RND-93-005) by Doreen Y. Cheng (NASA AMES)
Thirty-five parallel programming languages and fifty-nine parallel programming tools are evaluated.
----------------------------------------------------------------------- MULTIPROTOCOL NETWORK TRANSPORTS
Peer Logic (PIPES)
Peer Logic's Pipes provides a dynamic logical network layer that can deliver simple messages across a wide range of different protocols. Several companies are building products and architectures on top of Pipes. In particular, some of the RPCs and/or more sophisticated messaging products could run on top of Pipes to gain a more dynamic, heterogeneous capability. IBM recently announced an agreement with Peer Logic that will allow applications written to the Pipes API to run on IBM's Multiprotocol Network Transport.
ATT (Transport Layer Interface)
TLI is the application interface to Streams, a multi-protocol support architecture first developed in Unix System V.3. The X/Open Transport Interface (XTI) is based on TLI.
----------------------------------------------------------------------- MICROKERNELS
OSF(Mach)
The Mach kernel developed at CMU is the foundation of the OSF's OSF/1 operating system. It is not clear what impact microkernels will have on distributed computing environments of the future.
Chorus Systemes (Chorus)
Chorus will be used as the basis of the next release of Unix System V from the Unix System Labs. COOL is an object layer built on top of Chorus that provides system support for distributed object programming.(See the 9/93 issue of CACM on Concurrent Object-oriented Programming for more details).
Microsoft (NT)
The NT kernel will be the nucleus of Microsoft's next-generation Cairo Distributed Operating System.
----------------------------------------------------------------------- REMOTE PROCEDURE CALLS
NobleNet (EZ-RPC)
EZ-RPC is a client-server development tool that allows any C programmer to easily develop distributed applications on to of the TI-RPC. EZ-RPC will be bundled into future releases of Unix System V.
Netwise (Netwise-RPC)
Netwise has a RPC product that runs across many network protocols. They recently announced a product TransAcess that can send RPCs across IMS/DC. Netwise's Duet product provide transparent transport interoperability between TCP/IP, SNA and Novell networks. It is possible to use Oracle and MS-Window tools as a front-end to Netwise. ATT/Sun (TI-RPC)
TI-RPC is the most pervasive RPC as the underlying communication tool for NFS. TI-RPC runs on top of the TLI.
OSF (DCE/RPC)
DCE/RPC is the basis for the OSF`s Distributed Computing Environment. This environment offers a range of services such as security and threads that are not yet part of any of the OMG Object Request Broker specifications. The X/Open Tx-RPC is based on the DCE/RPC.
----------------------------------------------------------------------- CONVERSATIONAL PROGRAMMING
IBM(Common Programming Interface-Communications)
CPI-C is IBM's interface for cooperative conversational communication between distributed applications. It is also the basis for the X/Open standard in this area.
----------------------------------------------------------------------- MESSAGING PRODUCTS
System Strategies/IBM (MQ Series)
System Strategies makes a messaging product that runs across many network protocols. IBM and System Strategies will sell a product called MQ Series that will use IBM's Message Queuing Interface API on top of System Strategies messaging technology. MQI Series could be enhanced by porting it to run on top of Peer Logic's Pipes. The MQ Series could interoperate with Transaction Processing Managers by building an interface between messaging and transaction queues. The MQI API will be submitted to X/Open.
Horizon Strategies (Message Express)
Horizon Strategies has announced a future enhancement to their product that will be called Associative Resource Objects(AROs). AROs will allow pluggable communication behavior to be built on top of the basic Message Express system. The August 1993 issue of the Seybold Distributed Computing Monitor has a feature article on the ARO approach.
Covia Systems(Communications Integrator) Covia and Sun have signed a joint technology development agreement to investigate the potential of integrating the Sun RPC with the Communications Integrator.
Momentum Software(X-IPC)
X-IPC provides high-performance distributed shared memory, semaphores, and message queuing as an extension to single platform operating systems IPC. There has been some discussions of combining X-IPCs capabilities with that of other messaging products such as Message Express. It would also be possible to use X-IPC on top of a microkernel to provide distributed shared memory across a heterogeneous network. Some other messaging products(More information available on request) Creative System Interface (AAI) Digital (DECmessageQ) HP (Sockets)(BMS) IBM (DataTrade)(DAE) Suite Software (SuiteTalk) Symbiotics (Networks) ----------------------------------------------------------------------- PUBLISH AND SUBSCRIBE MESSAGING Sun(Tooltalk)
Sun's Tooltalk has been adopted by the COSE group as the common mechanism for asynchronous messaging between tools. Tooltalk runs on top of TI-RPC. Tooltalk will be the basis of the Events Services component of Sun's Object Request Broker Architecture.
Teknekron (Teknekron Information Bus)
The Teknekron Information Bus(TIB) is a reliable high-performance publish-and-subscribe system that features subject-based retrieval and complex messages. The product has been licensed by Microsoft for use in financial applications on NT. The Sematech consortium will also be evaluating TIB in a factory application. Expert Database Systems (Rnet)
Rnet is a new system with some of Teknekron's TIB capabilities. ----------------------------------------------------------------------- TRANSACTION PROCESSING MANAGERS
Unix Systems Lab (Tuxedo)
Tuxedo is the most widely used product in the open systems transaction management area. It runs on top of the Streams TLI or Sockets. The future relationship between transaction processing systems and object request brokers (e.g. Hyperdesk) is not well-defined at present.
Information Management Company (Open TransPort)
Open TransPort allows applications running under Tuxedo to transparently execute IMS/DC transactions using a TCP/IP gateway to MVS. A CICS version will be available in September.
NCR (TopEnd)
TopEnd has an architecture which defines an open interface to the communications manager. This will allow alternate communication mechanisms to be used without changing the other parts of the system. Transarc (Encina)
The Encina toolkit runs on top of a transactional extension to the DCE/RPC. It can also use the X-Open CPI-C protocol to communicate through CICS with mainframe resource managers.
IBM/HP/Transarc (Open CICS)
Open CICS duplicates the mainframe CICS interfaces on open systems platforms using the core of the Encina toolkit as a foundation.
----------------------------------------------------------------------- DISTRIBUTED WORKSTATION EXECUTION SYSTEMS
Aggregate Systems (NetShare)
NetShare provides network wide resource management and task execution for Unix systems. It uses a proprietary remote execution service but the architecture will allow the DCE/RPC or TI-RPC to be utilized also. NetShare could be a service in an object request broker architecture.
Platform Computing(Utopia)
Utopia provides transparent, fault-tolerant, distributed batch execution, load sharing and interactive services for Unix systems. Its remote execution model can support either a remote operation invocation or a conversational client-server interaction. The relationship between this type of product and transaction processing managers, object request brokers and system management products is an open question.
-----------------------------------------------------------------------
OBJECT REQUEST BROKERS
Hyperdesk (Distributed Object Manager)
Hyperdesk provides one of the first implementation of the OMG Object Request Broker. It currently runs on top of the Netwise RPC. Hyperdesk could also be layered on top of other messaging or RPC products. Novell is combining Hyperdesk with the Software Transformations Inc. portable desktop operating environment and the Serius object-oriented visual programming environment into a distributed application framework.
IBM Distributed System Object Model(DSOM)
The Distributed System Object Model is an extension of the programming language-independent System Object Model which is the basis of the OS/2 Workplace Shell. The DSOM will conform to the OMG ORB architecture. HP will be using the DSOM as part of its Distributed Object architecture and Sun has promised interoperability between DSOM and the Sun Distributed Object Environment. DSOM will initially use sockets for remote communication. DSOM currently has a proprietary Event Manager Framework for peer-to-peer communication.
Microsoft (Distributed OLE)
Distributed OLE is an extension of OLE 2.0 which will be part of the Cairo operating system. A Microsoft version of the DCE/RPC will be used for remote communication. Distributed OLE will probably not conform to the OMG architecture and no standard interface between OMG object request brokers and OLE has been proposed yet.
Iona Technologies Ltd. (Orbix)
Orbix is a full implementation of the current OMG Object Request Broker architecture. It also includes a C++ binding. ----------------------------------------------------------------------- SYSTEM MANAGEMENT
OSF (Distributed Management Environment)
The OSF's Distributed Management Environment will run on top of the DCE/RPC. The API's will be based on the OMG Object Request Broker.
Legent
Legent is a traditional mainframe system management vendor that is developing an open systems product. The product will run on top of Peer Logic's Pipes. Legent has also licensed the Galaxy portable desktop environment from Visix as part of its architecture. Legent is working with Tivoli Systems, one of the main contributors to the OSF/DME.
Digital Analysis (HyperManagement)
Digital Analysis is working with Hyperdesk to develop a system management product called HyperManagement that will run on top of Hyperdesk.
----------------------------------------------------------------------- DISTRIBUTED DEVELOPMENT/EXECUTION PRODUCTS
Texas Instruments (Information Engineering Facility)
Texas Instruments IEF is a mainframe CASE tool that is being extended for client-server applications. The client-server version will run on top of Peer Logic's Pipes. The 8/30 issue of Communication Week describes an agreement between TI and Microsoft to use the IEF Encyclopedia as a repository for Microsoft's desktop software development tools.
Independence Technologies (iTRAN)
Independence Technologies has a software development and execution toolkit that runs on top of transaction management systems. Currently only the Tuxedo version is available. A workflow component called iWORK was built on top of iTRAN but is not a current product. Intellicorp(Kappa)
Kappa includes an executable object-oriented design CASE tool front-end. It uses a communication component called CommManager that provides message-based peer-to-peer links between distributed objects. ISIS Distributed Systems (RDOM)
The Reliable Distributed Object Management(RDOM) system supports publish and subscribe messaging, object groups and fault-tolerance through replication. The Sematech Consortium will also be evaluating ISIS in their manufacturing architecture. There is a distributed Smalltalk/RDOM available from ISIS. ISIS has been ported to run on top of the Mach and Chorus microkernels.
Early, Cloud & Company (Message Driven processor)
The Message Driven processor(MDp) is an enterprise level workflow tool that runs on top of several mainframe communication protocols including the IBM/System Strategies MQ Series.
Expersoft(XShell)
XShell provides a distributed programming environment that encapsulates a proprietary asynchronous RPC inside C++ classes. Expersoft has organized a "Distributed Object Alliance" around XShell which includes Lucid(C++), Objectivity(OODB), Persistence(C++ to RDBs), Associative Design(Executable Object-models similar to KAPPA's), Logicon(C++ encapsulation of Fortran and COBOL), and MRJ(System Integration).
Cooperative Solutions(Ellipse) Ellipse is a development/execution product that runs on LANs. It claims to support versioning, application partitioning, portability, repository-based development, configuration control and distributed transaction management in multiple client/server environments.
SOME PERSONAL OPINIONS:
* Inter-application communication tools should be chosen based on the requirements of application areas. In particular, RPCs and ORBs are not the total solution. Many vendors and internal projects in end-user companies are using peer-to-peer messaging as the basic paradigm.
* Rules of thumb: APPLICATION-TYPE -> MIDDLEWARE TYPE Client-Server -> RPC or Conversational Communication Client-Services -> ORB or Distributed Transaction Manager Peer-to-peer -> Messaging Communication
* For large enterprise distributed computing, it will be necessary to have a foundation of robust communication and coordination across the three tiers of PC LANs, local servers, and mainframe systems. This will require integrating many tools and products. Future coordination environments should combine the capabilities of transaction processing managers, distributed development/execution/management systems, and object request brokers. The most challenging problem is to build enterprise-level transactional workflow processes linking together multiple local coordination managers. ----------------------------------------------------------------------- CONTENTS OMITTED DUE TO MAILING LIST LENGTH RESTRICTIONS -------------------------------------
