Overview

CICS® Service Flow Feature is a business service integration adapter for all CICS applications. It offers both tooling and run-time components. These components enable enterprise solution architects, enterprise integration developers, and CICS application specialists to create CICS business services for integration in Service-Oriented Architectures (SOA), business process collaborations, or enterprise solutions that exploit a loose coupling approach.

The CICS Service Flow Feature delivers the capability to implement CICS business services by composing a sequence of CICS application interactions. In a single offering, CICS Service Flow Feature delivers:

  • A graphical modeling integrated development environment that enables the creation of CICS business services by composing a flow of CICS application interactions.
  • A generation capability that transforms the composed flow of CICS application interactions to form a run-time application, highly optimized for the CICS environment, that retains the inherent qualities of service provided by the existing CICS application implementation.
  • A run-time component, known as the Service Flow Runtime, that extends the CICS Transaction Server for z/OS® (CICS TS) environment. It offers adapters that exploit CICS interfaces to invoke the CICS terminal-oriented transactions and COMMAREA programs as required by the service flow.

CICS business services built with and hosted in CICS Service Flow Feature expose business function interfaces that can readily be published as Web services in an SOA by exploiting the Web services capabilities of CICS TS V3.1. This approach complements and extends the Web services capabilities offered in CICS for use with composed CICS applications.

Additionally, these business services can be integrated as process steps in a business process orchestrated by a business process engine such as WebSphere® Process Server.

CICS Service Flow Feature preserves the natural modeling style of business integration solutions while shielding the solution implementer from the detail of the CICS application implementation. CICS application interfaces, including 3270 transaction screens and COMMAREAs, can be imported as components into the composition workspace. Imported CICS application components are composed to produce a CICS business service adapter that extends the value of CICS application components with a business service interface.

The CICS Service Flow Runtime adapters allow access to existing CICS transaction and application interfaces using non-invasive techniques, so that the CICS application assets orchestrated by the service flow do not have to be altered to support the CICS business service flow. This enables the fast reuse of existing assets while minimizing the risk of the new implementation.

Description

The CICS Service Flow Feature, a business service integration adapter for all CICS applications, delivers the tooling and runtime that enable CICS business services to be created more quickly and easily by composing a sequence of CICS application interactions. The high level business function interfaces exposed by the CICS business services enable effective integration with many styles of modern enterprise solution such as SOA, business process integration, J2EE distributed architectures, and message-based Enterprise Application Integration (EAI).

For many enterprises today, core LOB processes are implemented as custom CICS applications. Often these processes are fundamental to the value that an enterprise offers to its customers, suppliers, and partners. These applications capture, in their implementation, the optimized business behavior that an enterprise has built over many years. And as customer, supplier, and partner relationships have flourished and developed, the reliability, responsiveness, and robustness exhibited both within the enterprise and externally are perceived as the normal characteristic of enterprise service delivery.

It is imperative that, as these applications are reused, extended, and transformed in support of new solutions that meet new business requirements, the value of these applications preserves their existing quality of service (QOS).

As new business architectures such as application serving, business process integration, and message-based EAI have developed and become prominent, CICS transport technologies including MQ, IIOP, and JCA have been introduced to allow access to the business process segments implemented as CICS applications from these styles of solution architecture. CICS TS V3 extends this set by delivering Web services support, which enables the value and QOS of existing applications to be retained but repurposed for new contexts.

CICS Service Flow Feature extends and complements this approach. It enables CICS application interfaces to be composed to form CICS business services that expose high-level business function interfaces. The CICS business service captures the transition between many different application logic components in terms of a flow. The resulting business service performs a high level purpose (for example, order fulfilment or bill payment), that is meaningful to an external system as a reusable service.

Typically, modern enterprise solutions require business service level interfaces described using XML-structured data formats. Reuse of existing application components can significantly benefit new solution implementation by reducing cost and risk, and by speeding delivery. These benefits are further magnified if the implementations of the reused components are encapsulated behind an open-standard interface such as that offered by Web Services, since component reuse will not require platform-specific implementation knowledge.

Traditional CICS applications were designed to be accessed from a 3270 terminal. The applications exploit CICS-provided interfaces to generate and interpret the screen content and to manage the control and interaction with the 3270 terminal. Typically such applications were designed to deliver a sub-second response to a terminal user by exchanging small amounts of information in quick succession; in other words, to support a "fine grained" interaction pattern.

In some cases, well-structured CICS applications implement a separation of the 3270 presentation logic and the application business logic. They introduce the option of exposing a callable component interface typically implemented as a CICS COMMAREA that adheres to the fine-grained interaction pattern.

In order to implement an optimal method of integration between modern enterprise solutions and an existing enterprise system, the number of interactions between the systems should be minimized. This reduces the volume of request data being exchanged over the transport and the cost of data content processing in each system. This suggests a "coarse grained" interaction pattern across the external system boundary complemented by highly optimized processing of the request payload within the bounds of each system.

CICS Service Flow Feature introduces the capability required to compose fine-grained CICS application interfaces, both 3270 and COMMAREA, to form a CICS business service that exposes a coarse-grained business level interface. Using CICS Service Flow Feature, existing CICS application interfaces can be imported as reusable components. The CICS Service Flow Modeler delivers the flow modeling and mapping capabilities required to transform the behavior of the application components to form a business service without changing the underlying implementation. This enables QOS to be retained.

CICS Service Flow Feature delivers:

  • A graphical modeling integrated development environment that enables the creation of CICS business services by composing a flow of CICS application interactions
  • A generation capability that transforms the composed flow of CICS application interactions to form a run-time application, highly optimized for the CICS environment, that retains the inherent QOS delivered by the existing CICS application implementation.
  • A run-time component, known as the Service Flow Runtime, that extends the CICS TS environment by offering adapters that exploit CICS interfaces to invoke the CICS terminal-oriented transactions and COMMAREA programs, as required by the service flow.

CICS Service Flow Feature Service Flow Modeler is a multifunctional tool base on the Eclipse framework. It supports modern application architectures and the transformation and reuse of existing application processes.

It is designed to help leverage your investment, and the QOS, of existing enterprise information systems and CICS applications, while at the same time enabling the move towards SOA. The Service Flow Modeler lets you:

  • Model a newly composed business service — or flow — using processes or services and their interfaces
  • Capture existing screen or communication area interfaces and generate a new SOA suitable interface
  • Generate adapters to and from interfaces supporting both the accumulation of information — used in request and response processing — as well as data transformation activities between the flow and the interface
  • Expose business flows as a service or Web service

The Service Flow Modeler delivers a screen navigation mode. While in this mode, it is possible to record a sequence of 3270 screens in a CICS application to form a reusable component. So, when a business service request is invoked in CICS, the business service navigates the appropriate 3270 screen sequences, formulates a consolidated response, and sends a single service response to the requestor.

CICS Service Flow Feature generator consumes the modeled flow of CICS application interactions and produces:

  • COBOL source code that implements the modeled business service behavior
  • Run-time properties that are required to support CICS configuration
  • The JCL required for compilation

The run-time component produced by the generator directly exploits CICS-provided capabilities such as the Link3270 Bridge and CICS Business Transaction Services. This ensures a highly optimized implementation for the CICS environment that retains the inherent qualities of service delivered by the existing CICS application implementation. This approach to generation enables the navigation or sequence flow to be placed closer to the CICS target applications, allowing multiple transactions or applications to be accessed by invoking a single function of the CICS business service.

The Service Flow Runtime component of the CICS Service Flow Feature extends CICS TS with the components and configuration required for flow sequence orchestration.

The CICS Service Flow Runtime delivers adapters for access to existing CICS transaction and application interfaces using non-invasive techniques, so that the CICS application assets orchestrated by the service flow do not have to be altered to support the CICS business service flow. This enables the fast reuse of existing assets while minimizing the risk of the new implementation. If required, the CICS business service can persist state data related to the business service between multiple invocations of the CICS application interfaces.

Where there is a requirement to integrate information from non-CICS applications into the CICS business service, the Service Flow Runtime delivers a WebSphere MQ adapter that enables the CICS business service flow to access any MQ-enabled application, wherever it may reside in the enterprise solution architecture.

The base capabilities offered by CICS TS to access CICS application interfaces extend to capabilities such as:

  • Link3270 Bridge
  • Distributed Program Link (DPL)
  • WebSphere MQ Adapter
  • Front End Programming Interface (FEPI)

The CICS Service Flow Runtime exploits these capabilities when generating the CICS business service function to deliver the implementation needed to reuse the existing CICS applications as components in the CICS business service flow.

CICS business services built using CICS Service Flow Feature are optimized for the CICS TS environment and are directly deployed to it and have characteristics equivalent to traditional CICS applications. This approach ensures continued use of existing proven systems and operations management policies and practices while preserving important qualities of service such as security, scalability, and performance delivered by the existing CICS applications.

Other information

The following new information is provided concerning CICS TS.

MAP support in CICSPlex® SM Web User interface: Support for the MAP function is being added to the CICSPlex SM Web User Interface. It will be made available, via the service channel, on or before June 24, 2006.

OS/VS COBOL: As indicated in previous announcements, CICS runtime support for OS/VS COBOL (5740-CB1, 5734-CB4, and 5740-LM1) is not provided in CICS TS V3.1. To assist users of CICS TS in preparing for migration to CICS TS V3.1, a new function has been shipped via the service channel for CICS TS V2.2 and V2.3, in PTF for APAR PK10480. This writes a message to a new Transient Data (TD) Queue; this TD Queue is intended to record usage of deprecated functions in a region. A message will be written every time a new OS/VS COBOL program is loaded or reloaded.

In addition to these online warnings, an offline detection facility will also made available. This will be delivered as a SupportPac™, on December 2, 2005.

Support for mixed-case passwords: As described in the announcement of CICS TS V3.1, a function has been introduced that gives the ability to support the capability delivered in z/OS V1.7 for case-sensitive passwords. When this function is active, it will be indicated on the CICS-supplied signon panel.

This function has already been delivered on CICS TS V3.1. It will be made available in PTF for APAR PK08496 on CICS TS V2.2 and V2.3 on December 16, 2005.

Web Services Assistant: A new Java™ API for invoking the Web Services Assistant is made available in CICS TS V3.1 via the service channel, in PTF for APAR PK12805.

In addition, the Web Services Assistant API is available on Windows™, as a SupportPac.

Accessibility by people with disabilities

The Service Flow Runtime component of CICS Service Flow Feature has no interfaces to a user. The Service Flow Modeler is a part of WebSphere Developer for zSeries® V6.0.1, and experiences the accessibility characteristics of that product. The documentation for CICS Service Flow Feature comes as plug-ins to the CICS TS V3.1 Information Center. This is accessible to people with visual, physical, or hearing impairment, and incorporates features designed for users with visual impairment.

Section 508 of the U.S. Rehabilitation Act

CICS Service Flow Feature is capable as of December 16, 2005, when used in accordance with IBM's associated documentation, of satisfying the applicable requirements of Section 508 of the Rehabilitation Act, provided that any assistive technology used with the product properly interoperates with it.

Product positioning

The CICS Service Flow Feature enables the implementation of CICS business service interfaces to CICS Transactions and applications. CICS Business Services are inboard application business service adapters for the CICS environment that expose coarse-grained interfaces for optimized integration with business process choreography in Service-Oriented Architectures. These adapters enable fine-grained CICS application interfaces to be composed to form business service components that can be externally orchestrated, published as Web services, and integrated with J2EE and message-based solutions.

The highly optimized nature of the CICS Service Flow Feature infrastructure ensures preservation of the CICS application qualities of service when accessed from a SOA, a business integration choreography engine, a J2EE Application Server or EAI, or message-based solutions.

The capability delivered by the CICS Service Flow Feature ensures that the time to value of new enterprise solutions based on modern SOA, business process or J2EE architectures is enhanced by the ability to reuse existing software and data assets. Existing CICS application and data assets should be regarded in this context as reusable components. The CICS Service Flow Feature enables these components to be sequenced to form a series of related stateful service component invocations that support a business service interface.

The business service interface is published and is accessible at the boundary of the CICS environment by a variety of means including Web services, MQ, JCA, and IIOP. This ensures that the business service implementation is adjacent to the application and data components on which it relies, preserving the performance, reliability, scalability, and security characteristics that are critical to the solution, while enabling easy integration.

The CICS Service Flow Feature promotes a hierarchical approach to process-based software solutions. This architectural scenario describes specialized "subprocess" components, such as CICS business services, implemented and optimized for particular environments which host the components that they compose being orchestrated by external process server platforms. Platform application specific behavior is contained within the bounds of the application platform, and coarse-grained service interfaces are externalized at the subprocess boundary.

  • SOA/ESB and Business Process integration

    SOA and Business Integration solutions are able to exploit Web services to integrate with CICS business services implemented using the CICS Service Flow Feature. This approach benefits by optimizing the number of requests required to execute a given business service function in CICS. Also, the CICS business service function interface is exposed in a consistent Web service style that masks the detail of the underlying CICS application implementation. This enables effective service reuse by process integration developers who do not require deep CICS expertise to implement an effective solution.

  • J2EE distributed architectures

    WebSphere Application Server and other J2EE-based distributed applications can effectively integrate with CICS Service Flow Feature CICS business services by exploiting either the CICS Transaction Gateway JCA capability or by issuing EJB requests to the CICS Java environment. The high level business service interfaces exposed by the CICS business services increase the solution efficiency by reducing the number of JCA requests required; or, in the EJB scenario, by enabling a single CICS Link request to be made to execute a given business service function in CICS.

  • EAI and message-based solutions

    WebSphere Business Integration Message Broker and WebSphere MQ-based EAI solutions can exploit WebSphere MQ messages to integrate effectively with CICS business services implemented using the CICS Service Flow feature. This approach benefits by optimizing the number of requests required to execute a given business service function in CICS. Also the CICS business service function interface is exposed with an MQ Message format style that masks the detail of the underlying CICS application implementation within an understandable XML format. This enables effective service reuse by integration developers who do not require deep CICS expertise to implement an effective solution.

For each technology scenario described above, the capabilities of the CICS Service Flow Feature facilitate and promote a teamwork approach to enterprise solution development between the integration developer or process designer of the SOA solution and the CICS application specialist. The shared knowledge and understanding resulting from this mode of operation will benefit the effective implementation of solutions within an enterprise for many years to come, generating faster return on investment through effective application asset reuse.

CICS TS V2 SOAP for CICS feature: SOAP for CICS is a no-charge orderable feature of CICS TS V2 that is fully supported for use in a production environment. SOAP for CICS enables CICS application specialists to expose CICS application interfaces as SOAP services by implementing CICS integration logic that exploits inboard CICS adapter technologies such as Distributed Program Link (DPL) for CICS COMMAREA programs, and the LINK3270 Bridge for CICS terminal-oriented transactions.

SOAP for CICS should be considered by all customers of CICS TS V2 who want to enable CICS applications easily to participate in new business opportunities involving open standards technology. Solution assets developed for SOAP for CICS solutions benefit from easy forward migration to the Web services support in CICS TS V3.1, which offers an enriched Web Services capability, compliant with prevalent Web Services standards, supported by a performance-optimized architecture and enhanced tools and utilities for solution development.

The CICS Service Flow Feature complements the capability offered by other elements of the WebSphere portfolio:

WebSphere Host Access Transformation Server (HATS): HATS delivers tools to extend existing terminal applications quickly and easily to business partners, customers, and employees. In addition to transforming the user experience of existing applications, HATS can be used to transform and expand the connectivity of existing terminal applications by extending the applications as Web services. Web services generated with HATS are deployed to an IBM WebSphere Application Server.

The Service Flow Modeler capability of WebSphere Developer for zSeries V6.0.1 can be used in conjunction with HATS to translate 3270 or 5250-based interfaces to Web services, HTML, and XML-based interfaces.

Service Flow Modeler can be used with HATS, WebSphere Application Server, and any supported release of CICS TS to record CICS terminal-oriented application screen sequences and then, using HATS with WebSphere Application Server, to configure and deploy the results as Web services. This can be achieved either with WebSphere Application Server on zSeries or on a distributed platform. HATS on zSeries is able to coexist with any supported level of CICS TS.

This approach may benefit CICS TS V2 customers with an immediate need to integrate CICS 3270 transactions with an SOA using Web services, but who are constrained in forward migration to CICS TS V3.1 or have limited availability of CICS application specialist solution development skills.

The solution assets resulting from this approach can be redeployed from Service Flow Modeller directly onto CICS TS V3.1, enabling easy forward migration of existing solution assets.

WebSphere Process Server: WebSphere Process Server V6 is a single, integrated platform with the combined benefits of a robust J2EE runtime delivered by WebSphere Application Server and rich, sophisticated business process integration capabilities. It delivers business flexibility on a highly scalable, reliable platform. WebSphere Process Server V6 is the first to offer robust process automation, advanced human workflow, business rules with rich application-to-application (A2A) and business-to-business (B2B) capabilities all on a common, native SOA platform with full Enterprise Service Bus (ESB) connectivity.

WebSphere Process Server supports the Common Event Infrastructure as the foundation for monitoring applications. WebSphere Process Server implements a number of components/services that can be used in an integration solution. Service Component Architecture is the invocation model supported by WebSphere Process Server. Every integration component is described through a consistent interface style. Service Component Architecture (SCA) Bindings specify the physical description of components. Services can be accessed as Java Objects (PoJos), EJBs, Web services, JMS Messages and Adapters.

Business objects are the universal data description supported by WebSphere Process Server for describing data going in and out of services. Business objects are based on the service data object (SDO) standard. WebSphere Process Server includes business rules capabilities that extend to rule sets (if/then rules) as well as decision tables.

In addition to automated business processes, WebSphere Process server supports Human Task flow with the Human Task Manager. This allows for implementation of AdHoc Staff flows.

WebSphere Process Server delivers for Business State Machines, as another method of modeling, a business process. Some processes that are highly event driven, such as an order which could be canceled at any point during the order process, require a state machine paradigm model. WebSphere Process Server allows a service model to be described using unified modeling language (UML) state machine diagrams to define such event-driven business processes.

WebSphere Process Server supports four kinds of mediations that allow information flow between process stages:

  • Maps: To transform one kind of business object into another
  • Relationships: To allow key management for same objects in different data stores (for example, a customer record has a different identifier in SAP than in Siebel)
  • Interface Mediation: To translate between semantically identical but syntactically different services — for example, updateCustomer (Customer) to updateCustomerInSAP (SAPCustomer)
  • Selector: To allow the invocation of a different component (with the same interface) based on business rules

WebSphere Integration Developer (WID) Integration Adapters: WID Integration Adapters deliver a mechanism that allows for integration of existing Enterprise Information System infrastructure and WebSphere Process Server applications. They comply with the integration pattern for J2EE distributed architectures described previously in this section, and support both JMS and JCA transports. WID allows JCA-based access to CICS applications encapsulated within a consistent SCA style interface and exploits the capabilities of the CICS Transaction Gateway.

WebSphere Process Server applications that utilize this SCA style of integration for access to CICS implement a "fine grained" interaction pattern. The integration logic and CICS parameter transformation and mapping required to support interaction with the CICS applications must be built into the WebSphere Process Server solution implementation, and require CICS knowledgeable skills to implement.

IBM recommends that enterprises considering this nature of solution assess the advantages of a Web Services implementation style as an alternative.

The CICS Service flow feature can be used to complement the WID adapter approach by providing access to the high-level business service interfaces exposed by the CICS business services. This will increase the efficiency of the implementation by reducing the number of SCA requests required for effective integration.

Compatibility

MQSeries® Integrator Agent for CICS TS V1.1 (MQSI Agent for CICS, 5655-F25): On October 28, 2003, in the announcement of CICS TS for z/OS V2.3, IBM announced the intention to include in that product capability which would replace the MQSI Agent for CICS run-time function. On June 7, 2005, IBM announced the withdrawal from marketing of MQSI Agent for CICS, effective December 31, 2005.

Note also that, as IPLA licensed software, the support plan for MQSI Agent for CICS will follow the announced IBM software support lifecycle policy, which features:

  • A minimum of 3 years of support beginning at the general availability date of the version/release of the product (for MQSI Agent for CICS, the applicable general availability date is April 30, 2004)
  • End of support (EoS) announced at least 12 months prior to when it is effective
  • EoS to be at least 12 months after withdrawal from marketing
  • The EoS date to be either April 30 or September 30

The announcement by IBM on June 7, 2005 also stated that:

  • The tooling capability in MQSI Agent for CICS, the MQSI Agent for CICS Adapter Builder, is replaced by the Service Flow Modeler in WebSphere Developer for z/OS V6.
  • The server runtime function of MQSI Agent for CICS is replaced by capability in CICS TS for z/OS V3.1.

Today's announcement of the CICS Service Flow Feature extends this:

  • It delivers a single offering that combines new tooling and run-time capability that replace MQSI Agent for CICS in a single package.
  • The CICS Service Flow Feature includes the run-time functions of MQSI Agent for CICS, and offers a strategic migration path for MQSI Agent for CICS.
  • The CICS Service Flow Feature delivers the integration technology referred to in the previous announcements as a no-charge, fully supported optional feature.
  • The CICS Service Flow Feature delivers full backward compatibility with the MQSI Agent for CICS Server runtime, to enable seamless forward migration of MQSI Agent for CICS solution assets.

Existing generated MQSI Agent for CICS flows will continue to run under the CICS Service Flow Feature without modification.

Note, however, that a migration process will be necessary for MQSI Agent for CICS Adapter Builder artefacts to be used by the Service Flow Modeler to generate new CICS Service Flow Runtime artefacts. A migration utility to assist in this will be available.

Message Driven Processor (MDp): In 2003, IBM notified all MDp customers of the discontinuance of service on MDp effective December 31, 2004, with service extensions available. IBM recommends that all customers still using MDp urgently consider implementing a strategic forward migration to the CICS Service Flow Feature.

Migration services: Skilled consultants from IBM Software Services for WebSphere are available to assess your current MDp environment and discuss for CICS integration initiatives, including proof of concept and migration and/or re-engineering of existing MDp applications. Please contact your IBM representative or a Software Services Sales Representative for further information on services offerings.
