    Abstract

    (For IBM US, No Longer Available as of March 21, 1994)

    The IBM SAA DataTrade* MVS/ESA Edition is a new program within the DataTrade family of communications licensed programs. DataTrade provides a consistent application program interface (API) for data transfer among applications residing on the same processor, or among distributed applications running on different processors under different operating systems.

    Through the DataTrade API, customers and independent software vendors may develop distributed application systems that operate on IBM and non-IBM platforms using the DataTrade API requester/server protocol, without concern for the different underlying network protocols.

    The DataTrade API implemented on SAA DataTrade MVS/ESA provides bindings for the following IBM SAA licensed programs:

    • IBM SAA AD/Cycle C/370 (Compiler) Version 1.1 (5688-216)
    • IBM SAA AD/Cycle COBOL/370 (Compiler) Version 1.1 (5688-197)
    • IBM SAA AD/Cycle Language Environment/370 (CLE/370) Version 1.1 (5688-198)
    • IBM C/370 Compiler Version 2.1 (5688-187)
    • IBM VS COBOL II 3.1 Compiler/Library (5688-023)
    • IBM VS FORTRAN Version 2.4 Compiler/Library (5688-087)
    • IBM OS PL/I Version 2.3 Compiler/Library (5668-910).

    SAA DataTrade MVS/ESA provides the extended requester/server API which allows communication with previous DataTrade releases.


    Product Positioning

    DataTrade is a high level requester/server application-to-application SAA compliant API that exploits SAA communications paradigms. This cooperative processing enabling product is applicable to all industries. Within Financial Services Industries (FSI), it is positioned as the enterprise API for IBM's Financial Application Architecture (incorporates and supersedes the Wholesale Banking Design Principles). It facilitates application connectivity and integration in both LAN and WAN environments.

    Description

    Customer Value

    Solutions in the information systems (I/S) environment often consist of many machine and programs suppliers integrating their offerings in a distributed customer solution.

    Through its consistent powerful, high-level API, DataTrade enhances user productivity, provides business solutions, enables growth, protect the customer's investment, and supports system management by:

    • Allowing the application programmer who has little or no knowledge of communication protocols to build sophisticated distributed applications, quickly and reliably

    • Reducing, significantly, the amount of application program maintenance required when network communications changes are made

    • Being a key facilitator in enabling consistent communication among application programs from multiple sources; reducing, significantly, the risk and expense of integrating applications from different sources, and highlighting IBM's commitment to total business solutions.

    • Making it easier to integrate and maintain disparate applications across distributed systems, allowing DataTrade to play a key role in business growth

    • Reducing the amount of application program maintenance required because of changes in network communications; protecting, significantly, customers' application investment

    • Allowing portions of a distributed application to be changed, without affecting the rest of the distributed system

      • Improving, vastly, system management capabilities and reducing disruption across a distributed system

      • The capability of administering DataTrade from a central location complements the IBM strategy for systems management.

    Technical Description

    Overview of DataTrade Series

    This is an overview of DataTrade across all platforms. The specific languages, communications protocols, and features provided by DataTrade vary by platform. The support provided by SAA DataTrade MVS/ESA is described in the sections on communications, data interchange, administration, application program support, interoperability, and packaging, which follow.

    DataTrade provides a consistent application program interface (API) across different IBM and OEM platforms and programming languages. The supported languages include C, PL/I, FORTRAN, and COBOL, and IBM's SAA AD/Cycle languages, C/370 and COBOL/370. Communication between the application program and DataTrade is accomplished by a call interface comprised of seven verbs and appropriate parameters.

    DataTrade provides point-to-point communication between applications on the same processor or, by employing SNA and/or TCP/IP, between applications distributed across multiple IBM and OEM platforms. DataTrade also provides data interchange facilities such as automatic ASCII/EBCDIC conversion, and on host platforms, CCSID (Coded Character Set Identifier) conversion and data field transposition.

    On workstations, DataTrade provides a reliable LAN broadcast facility which allows applications to be developed using an efficient means of distributing broadcast data to a large number of workstations using a single call. Applications may receive all broadcast data, or a part of the data, depending on whether the data is defined as tagged or untagged.

    DataTrade provides a single focal point for the administration of multiple DataTrade installations across a network. This includes the authorization of application programs to DataTrade services, specifying the location of services provided within a network, the identification of installation supplied exits, and the specification of data interchange capabilities. DataTrade can be controlled through locally provided operator functions, or through the remote and automated services of SystemView.

    DataTrade Licensed Program packaging allows customers to design and implement cost-effective solution to their distributed application needs.

    Communications

    DataTrade supports point-to-point communication through its API. The API is comprised of seven callable verbs and appropriate parameters. In a typical use of DataTrade the API enables the application program to send a request to another application and either wait for the response or continue with its own execution. DataTrade sends the request to the correct destination, where a server program retrieves the request, performs the necessary processing and provides a response. DataTrade routes the response back to the original requester and presents the response to the requesting application when needed. DataTrade supports requester/server as well as conversational models of application-to-application communication.

    DataTrade allows applications to serve and request 'services'. A service identifies a function, such as the retrieval of a customer address. DataTrade maintains the necessary information to identify where services are provided in the network, and what applications have outstanding requests. Thus, an application can request or provide a service without knowledge of the logical or physical location of the other applications with which it is communicating. It is through this means that DataTrade provides local/remote transparency and hides the network topology from the application, which significantly reduces the complexity of the application, and amount of application program maintenance required due to network changes.

    DataTrade formats its Information Unit (IU, the mechanism to pass data between DataTrades), according to standards for self-defining data streams. Therefore, customer applications that use DataTrade for remote communications can participate in future network management enhancements.

    DataTrade provides improved communication availability through Intermediate Network Node (INN) routing, so that multiple communication paths between distributed applications can be defined. If the standard network path between two DataTrades is disrupted, INN allows for the definition of an alternate path through an intermediate node.This can be accomplished through changes in the DataTrade administration tables without impacting the application programs themselves.

    Data Interchange

    Common in a network of distributed applications is a variety of data formats, character code representations, and platform specific data storage conventions. DataTrade has several facilities to ease data interchange between distributed applications.

    For all platforms:

    • ASCII/EBCDIC conversion: DataTrade provides facilities to convert ASCII coded data into EBCDIC coded data when data is transmitted from a workstation into the IBM host environment. When data is retransmitted from an IBM host into the workstation environment the reverse conversion occurs. This facility is provided automatically without application involvement.

    For MVS/ESA platform only:

    • CCSID conversion: DataTrade provides facilities to convert application data from one character set to another. The character set conversion is specified through the DataTrade administration facility and is specified per application. DataTrade automatically invokes the CCSID conversion facility, if specified, thus removing the need for applications to be aware of the character sets used by remote applications with which they communicate.

    • Data field transposition: Distributed applications pass data through networks in IUs. Quite often remote applications require the same data be arranged in different locations within the IU. DataTrade provides facilities that apply data field transposition maps upon the data within the IU without any intervention by the application. The data transposition maps are specified through the DataTrade administration facility and are based upon services names. DataTrade automatically invokes the appropriate data field transposition map, if specified, thus removing the need for remote application programs to accommodate differences in data location within the IU.

    By providing these facilities, all defined and maintained outside the scope of application programs, DataTrade increases application programmer productivity, facilitates migration of applications across the network, and reduces impact to applications due to changes in the network.

    Administration and Operation

    DataTrade provides a single facility, located on a DataTrade workstation platform, to build and maintain the administrative data used to customize each DataTrade installation within a network. Many aspects of DataTrade function can be specified by the customer, including:

    • Authorization or de-authorization of application programs to use DataTrade function
    • Identification of network locations where services are provided
    • Definition of data interchange facilities, installation defined user exits, and communication path(s) between DataTrades

    DataTrade provides a full-screen operator facility that allows each installation of DataTrade to be controlled by local personnel. Functions provided include:

    • Monitoring DataTrade through application, service and IU logs, and an alert log containing exception conditions.
    • Refresh of DataTrade administrative data
    • Termination of DataTrade

    In addition to operation by local personnel, DataTrade, through the use of SystemView services, can be operated remotely using the full-screen operator facility. Through the use of DataTrade-generated SNA alerts and SystemView, DataTrade can be fully automated.

    For each DataTrade domain consisting solely of DataTrade System/88 and/or DataTrade Edition for Sun** systems, configuration, administration and operation must be performed using a properly configured, AIX* DataTrade/6000 or SAA DataTrade/2 administrative workstation. Such administrative workstations may serve this function for any DataTrade domain to which they are physically attached, and may also be used for other DataTrade functions.

    Application Program Support

    The DataTrade 'user' is the Independent Software Vendor (ISV) or customer application programmer. DataTrade provides many ease-of-use and productivity aids to assist the application programmer, including:

    • Consistent API verbs and parameters, as well as consistent return code/reason code (RC/RS) structure across all DataTrade platforms and languages. This facilitates code reuse, and preserves the DataTrade skills built within the programming staff.

    • Installation exits are provided in several areas of DataTrade execution to further facilitate the customization of DataTrade function. For instance, customer written programs can be executed through DataTrade exits to supplement DataTrade security and data transformation functions.

    • Asynchronous exits are provided to allow sophisticated application programs maximum flexibility in using the DataTrade product. These exit are used to send various status messages to the application, as well as notify an application that specific requested data has arrived and is available to the application.

      Note: When writing applications for an IMS/ESA environment, the IMS/ESA Transaction Manager is required only if applications use asynchronous options with DataTrade verbs (See Programming Requirements section for specifics).

    • Application programmers or operations staff may monitor the behavior of DataTrade through an alert log, and of their applications through application, service and IU logs, in either a development or production environment.

    Interoperability

    DataTrade has several means of providing interoperability between DataTrade host applications and workstation applications: the Distributed Application Program Interface Licensed Programs, which allow customers to develop new workstation applications, and the MVS connectivity application included with the DataTrade initial workstation release Licensed Programs.

    Distributed Application Program Interface

    DataTrade host platform applications may communicate directly with workstation applications developed using the Distributed Application Program Interface (DAPI) Licensed Programs.

    DAPI workstation applications use the DataTrade host API, and may either request or provide DataTrade services. Each workstation supporting DAPI applications must have the appropriate Distributed Application Program Interface Licensed Program installed, and must be directly connected to the DataTrade host platform via APPC.

    MVS connectivity application

    Because of environmental differences, DataTrade initial workstation release platforms cannot communicate directly with DataTrade host platform applications or DAPI workstation applications. These applications may communicate through the MVS connectivity application (ConnAP) included with the DataTrade initial release Workstation Licensed Programs.

    The ConnAP appears to DataTrade host applications as a DataTrade host application, and to DataTrade workstation applications as a DataTrade workstation application. It is defined to the DataTrade host system as the server for those functions provided by DataTrade workstation applications, and to the DataTrade workstation system as the server for those functions provided by DataTrade host applications. To provide DataTrade workstation application services to DataTrade host applications, it fields requests for those DataTrade workstation service(s) it is defined to support, issues the requests for the DataTrade workstation service, and returns the DataTrade workstation application's response to the DataTrade host application. Similarly, Connectivity Application may provide the services of DataTrade host applications to DataTrade workstation applications.

    The API used by the ConnAP for communication with the DataTrade host system is similar to that provided by the Distributed Application Program Interface Licensed Program in that it supports only the DataTrade host API verbs; the DataTrade workstation Broadcast facility is not supported. Also, the length of user application data and/or exception data is restricted to the DataTrade workstation limitation (1728 bytes).

    Note: Since DataTrade host platforms support the APPC protocol only, and since the DataTrade Series for Sun Licensed Programs do not support APPC, the ConnAP is not provided with the DataTrade Series for Sun Workstation Licensed Program (5601-409). Applications on this platform will still be able to communicate with DataTrade host applications as long as one of the above platforms that supports the ConnAP exists in the DataTrade workstation domain.

    MVS Connectivity Application Description

    The MVS connectivity applications (ConnAP) allow DataTrade workstation applications to communicate with DataTrade host applications. It does not provide DataTrade host function to DataTrade host applications, nor does it provide DataTrade workstation function to DataTrade host applications. For example, Installation Exits and extended request/response areas are not available to DataTrade host applications, and LAN broadcast is not available to DataTrade host applications.

    ConnAP minimizes the impact to all DataTrade initial workstation release customers that require communication with DataTrade host applications. To accomplish this goal the ConnAP functions as a "go between" for DataTrade workstation and DataTrade host.

    To DataTrade workstation requester applications, ConnAP appears as a DataTrade host server application; to DataTrade workstation server applications, ConnAP appears as a DataTrade host requester application. To DataTrade host requester and server applications, ConnAP appears as a DataTrade workstation server or requester, respectively.

    The ConnAP operates by fielding requests for the DataTrade workstation or DataTrade host services for which it has been defined as the server in the other environment. It reissues these requests to the actual DataTrade host or DataTrade workstation server application, retrieves the response and returns it to the original requesting application.

    ConnAP limitations

    Because ConnAP communicates with both DataTrade workstation and DataTrade host systems, it can use only the verbs, parameters and features common to both DataTrade systems. The following section lists the more important limitations on ConnAP function.

    • ConnAP must be installed on a DataTrade workstation that is directly connected to a DataTrade MVS/ESA system by APPC.

    • ConnAP does not support or issue the DataTrade workstation broadcast facility verbs.

    • ConnAP will only support the maximum DataTrade workstation request, response and exception data area sizes.

    • Services handled by ConnAP will exhibit performance degradation relative to native DataTrade workstation or DataTrade host services.

    Migration of DataTrade workstation applications to DataTrade host

    Some DataTrade workstation applications may have to be modified to handle synchronous and/or asynchronous status messages.

    DataTrade workstation applications can be ported to DataTrade host platforms. Changes to the DataTrade workstation applications will be required in order for take advantage of the expanded capabilities of DataTrade host.

    Limitations
