Overview

The IBM MQSeries® Integrator Agent for CICS® Transaction Server (MQSI Agent for CICS) is a product for application integration, running on z/OS®. It enables functional migration from the Message Driven processor (MDp) product delivered by IBM as PRPQ 5799-A66. Functional enhancements to MQSI Agent for CICS are being introduced, delivered by the service channel.

The MQSI Agent for CICS consists of two components:

  • MQSI Agent for CICS Adapter Builder: A build time component, runs on Windows™ and uses tools that look and feel similar to those of WebSphere® MQ Integrator® Broker V2.1.
  • MQSI Agent for CICS Server run time: A run time component, runs with CICS Transaction Server for z/OS V2.2 or V2.3 as a CICS application on a z/OS server. MQSI Agent for CICS Server run time uses CICS Business Transaction Services (BTS) to manage the interrelationship, commit scope, recovery, and restart of the actions that make up a business transaction.

Used together, the build time and run time components of MQSI Agent for CICS enable the construction and execution of adapters to process requests from client applications for business applications running on host systems, in particular CICS and IMS™.

The adapter runs when the MQSI Agent for CICS server run time receives a request from the client application. If the client application is WebSphere MQ-enabled, the request is in the form of a WebSphere MQ message. WebSphere MQ-enabled applications use the IBM WebSphere MQ-CICS bridge as the interface between a WebSphere MQ-enabled client application and CICS. Any other client application capable of initiating a CICS program can use a CICS-supplied interface to pass a request to run the adapter. A CICS-supplied interface can be ECI, EXCI, EXEC CICS LINK, or SOAP for CICS.

Target IMS applications may be driven via FEPI. Target CICS applications may be 3270 applications driven via FEPI or Link3270 Bridge, or COMMAREA applications driven through a Distributed Program Link (DPL). MQSI Agent for CICS contains server adapter programs that handle these four classes of applications.

Description

MQSeries Integrator Agent for CICS Transaction Server (MQSI Agent for CICS) was originally announced by Software Announcement 201-059 , dated March 13, 2001. MQSI Agent for CICS is the successor to the Message Driven processor (MDp) product (originally available from Early, Cloud & Company, and more recently delivered by IBM as a PRPQ (5799-A66)). It provides a range of requirements identified by MDp customers as important for sustaining their MDp investment. Significant functional enhancements are now being provided to MQSI Agent for CICS.

MQSeries Integrator Agent for CICS Transaction Server consists of two components, the MQSI Agent for CICS Adapter Builder, and the MQSI Agent for CICS Server run time. Used together, the MQSI Agent for CICS build time and run time components enable the construction and execution of sophisticated adapters to process requests (business transactions) from client applications.

Using the build time component, the user performs a series of processes, including microflow modeling, to build an adapter. As output from the build time, an adapter consists of COBOL (source and copybooks) and JCL.

After an adapter has been built, the user moves it from the build time environment to a z/OS server, where it is compiled as a CICS application. In its final form, the adapter consists of COBOL and CICS executables.

The adapter runs when the MQSI Agent for CICS server run time receives a request message from a client application. Requests from client applications must be contained in a CICS communication area (COMMAREA). A client application can be any WebSphere MQ-enabled application, or any application capable of initiating a CICS program through a CICS-supplied interface (that is, ECI, EXCI, or EXEC CICS LINK). Examples of client applications include:

  • WebSphere Business Integration Message Broker V5.0.1
  • WebSphere MQ Workflow V3.4
  • Local, remote, or Client CICS applications
  • Applications running under WebSphere Application Server (any platform) and using Java™ connectors to access CICS programs
  • Web Services clients using Simple Object Access Protocol (SOAP)

If the client application is WebSphere MQ-enabled, the request is in the form of a WebSphere MQ message, and the application uses the WebSphere MQ-CICS bridge to pass the request message to the run time. The target application is driven via the WebSphere MQ server adapter program through MQPUT and MQGET commands. Other client applications (as long as they can initiate a CICS program) use a CICS-supplied interface to pass the request message to the run time.

MQSI Agent for CICS may also be used to support federated business process integration, where another product such as WebSphere Business Integration Message Broker is responsible for the overall business flow, managing business context state, multiple request and reply interactions, asynchronous processing, overall business flow compensation, and the continuation of one logical request through multiple requests, if required.

Adapter request processing can invoke server adapter programs in any sequence. The sequence is determined using the Adapter Builder component.

  • Existing CICS transactions (including custom programs) via a Distributed Program Link (DPL)
  • Existing CICS or IMS (or other) applications via a 3270 data stream using CICS Front End Programming Interface (FEPI)
  • Existing CICS or IMS (or other) applications via application data structure using Link3270 bridge
  • WebSphere MQ-enabled applications via WebSphere MQ

MQSI Agent for CICS Server run time

The run time component contains the following elements:

  • The server adapter programs: Any one of four types of programs in the run time component that perform the business transaction activity defined within a microflow at build time
  • The navigator programs: Perform adapter request processing, manage states during the microflow and invoke the server adapter programs
  • Support for custom programs: Custom programs must be written according to a specification that is part of MQSI Agent for CICS
  • An error logging program
  • Support for compensation flows, journaling, and audit levels using the BTS facilities of CICS
  • A range of utility programs to support the run time component

MQSI Agent for CICS server adapter programs perform the processing modeled in the microflows (also sometimes referred to as connector flows, micro-flow scripts, navigation scripts, or micro-control flows). The server adapter program processing may:

  1. Initiate local programs using EXEC CICS Link.
  2. Perform screen navigation, by way of an interactive request and reply dialog with a 3270-type CICS or IMS application. This can be accomplished in either of two ways:
    • Using the FEPI function of CICS, automatically parsing 3270 screens sent by the application, identifying their fields, attributes, and data, constructing and sending suitable replies including keystrokes based on the modeling and simple business logic
    • Using the Link3270 bridge, intercepting terminal-related commands, since there is no real 3270, using the input supplied in the COMMAREA to satisfy input commands (RECEIVE, RECEIVE MAP, and so forth), and collecting the output from output commands (SEND, SEND MAP, and so on) in buffers, based on the modeling and simple business logic
  3. Synchronously perform WebSphere MQ PUT and GET commands, enabling the client application to maintain responsibility for the overall business flow.
  4. Initiate remote CICS programs via DPL using EXEC CICS Link. These programs may include complex logic rules.

To do this, there are four types of server adapter programs:

  1. The FEPI server adapter program, which interfaces to 3270-type CICS and IMS applications, and performs screen navigation
  2. The Link3270 Bridge adapter program, newly introduced at this time
  3. The CICS server adapter program that interfaces to CICS transactions via DPL, and can also include custom programs developed to augment the supplied function
  4. The WebSphere MQ server adapter program that interfaces with WebSphere MQ enabled applications

The server adapter programs are generated as a result of modeling using the build time component of MQSI Agent for CICS.

The navigator programs, like the server adapter programs, are generated as a result of modeling via the build time component.

MQSI Agent for CICS Adapter Builder: The build time component of the product runs on Windows. It is provided on CD-ROM for installation using InstallShield.

It consists of the following elements:

  • A Control Center, similar to the Control Center of the IBM WebSphere MQ Integrator and to that of the IBM WebSphere MQ Adapter Offering, with the addition of support for the flow components and additional primitives of MQSI Agent for CICS. It supports the modeling and definition of the navigators and of the four types of server adapter programs. Definitions are stored as eXtensible Markup Language (XML) documents in the Control Center's repository.
  • Importers that collect modeling information from 3270 data streams, from COBOL record descriptions, and from BMS source files (a facility newly introduced at this time), and represent them as structured data types in the repository of the control center. The structured data types can then be used during modeling. A subset of IBM Host On-Demand is used to perform the build time 3270 terminal emulation function for the capture of the 3270 dialogs.
  • A Generator facility running in the same system as the control center, that enables the run time component to behave as modeled in the build time. This reads from the XML documents in the repository the definitions of the navigators and the four types of server adapter programs, and from them generates source code in COBOL (source and copybooks), together with the corresponding Job Control Language (JCL) for installation in the run time environment. The generator sends these to the system containing the run time component, and initiates the compilation in the run time machine of the source code into the executables of the navigators and the server adapter programs.
  • A Repository, a directory in the builder's file system that contains the messages and models.

Delivery: The enhancements described in this announcement are delivered by the service channel, as PTF for APAR PQ84425. The Adapter Builder, with this level of service, is at V1.1.3. The Server run time at V1.1.0, with successive service up to this level, remains at V1.1.0. For convenience, the product with these enhancements is referred to as V1.1.3.

Additional information

As was stated in Software announcement 203-296 , dated October 28, 2003, CICS Transaction Server for z/OS V2.3, IBM intends to include the run time functions of this product in a future release of CICS Transaction Server.

Product positioning

MQSeries Integrator Agent for CICS Transaction Server enables migration from the MDp product, and enables these customers to migrate to a business integration solution based on CICS, while protecting the investment they have made in MDp task objects.

With MQSI Agent for CICS, customers can also create adapters for integrating business applications across Enterprise Information Systems, such as CICS and IMS, providing effective re-use of existing assets such as 3270 applications. Consolidating the integration activities in the host environment helps reduce the risk, complexity, and cost of creating point-to-point integration solutions. Thus, integration solutions can be created with high performance, scalability, and availability by exploiting the robust infrastructure provided by CICS Transaction Server for z/OS. It enables these applications to be combined into larger units which perform a useful business service. These services may be invoked via any supported access interface to CICS, including JCA, IIOP and SOAP.

MQSI Agent for CICS creates adapters that are intelligent and that use a standard interface that remains stable even though the application changes. It provides the programs and environment that enable adapters to run, manage, and fulfill business transactions. It controls the execution of complex business transactions and assists in managing the interrelationship, commit scope, recovery, and restart of the actions that make up the business transaction.

MQSI Agent for CICS may use both 3270 Bridge and FEPI together as an integration point for accessing new CICS BMS and older 3270 data stream applications.

IBM Host Integration products are commonly marketed as providers of general purpose 3270 emulators to replace real 3270 hardware or 3270 emulators. Neither the CICS 3270 Bridge technology, nor FEPI technology can be used to provide a general purpose 3270 emulation solution.

Since Host Integration products process a 3270 data stream, the application, or CICS, must generate a 3270 data stream. CICS 3270 Bridge technology intercepts the application at the API level. With CICS BMS, the overhead of generating a 3270 data stream is avoided.

Using MQSI Agent for CICS with either CICS 3270 Bridge technology or FEPI technology, the following performance benefits are provided:

  1. 3270 screen navigation can be provided within CICS. A single business-client request can result in multiple 3270 transactions being run to satisfy the business response. This can greatly reduce the number of interactions between the business client and CICS, and avoids the navigation overhead, resulting in improved response time.
  2. 3270 emulation at the terminal level, including field attribute and modified data tag processing, as well as merging a SEND, NO ERASE data stream with the current screen contents, can be provided by MQSI Agent for CICS running under CICS. This 3270 emulation avoids the 3270 emulation overhead.

In summary, the IBM Host Integration products provide the best general purpose 3270 emulation solution, and these products can be customized to provide refacing for 3270 and 5250 applications on any platform. MQSI Agent for CICS with CICS Bridge Technology provides the best performing solution, in terms of response time and scalability, for accessing CICS 3270 applications on z/OS.
