Increased integration of CICS applications

These enhancements include facilities to reuse CICS applications within broader on demand business scenarios, using standard interfaces — primarily Web services and Java 2 Platform, Enterprise Edition (J2EE) connectors — and other industry communication protocols.

Web services support

CICS Transaction Server, Version 3.1 extends its Web services support beyond the Simple Object Access Protocol (SOAP) for CICS function that was available optionally with IBM CICS Transaction Server, Version 2. Together

with a range of extensions and new capabilities, this support now enables CICS business logic to be exposed as Web services, as part of a service- oriented architecture (SOA). These extensions include support for WS-Security to help protect SOAP messages. Support is also provided for distributed transaction-coordination capability compatible with the WS- Atomic Transaction specification

to help ensure that CICS Transaction Server can adhere to Web services standards.

CICS applications can naturally act in the role of both service provider and service requester, in cases where the services are defined using Web Services Description Language (WSDL). The ability of CICS Transaction Server to act as a service provider means that it is relatively simple for you to transform an existing CICS application into a Web service. The ability of CICS Transaction Server to act as a service requester means that a CICS application can issue

a single CICS command to use a Web service provided by any external provider.

To ease your ability to transform a CICS application into a Web service, IBM has included the CICS Web Services Assistant, a build-time capability provided to create WSDL

document from a simple language structure, or a language structure from an existing WSDL document. This support is provided for COBOL, C/C++ and PL/I. The assistant also generates information used to enable automatic run-time conversion between SOAP messages and containers and COMMAREAs. These capabilities help ensure that you do not have to write your own code to parse inbound messages and to construct outbound messages.

Enhanced HTTP support

CICS Web support is enhanced by upgrading CICS Transaction Server HTTP support to comply with the HTTP, Version 1.1 specification. Outbound HTTP support has also been added, so that CICS can act as both an HTTP server or as an HTTP client using simple EXEC CICS commands.

CICS Transaction Server also supports pipelining and chunking of messages. You can use new resource definitions, known as uriMAP definitions, to manage the HTTP server facility with- out needing to customize your analyzer program. CICS Transaction Server automatically creates virtual hosts using these definitions, so multiple host

3.1 specifications

IBM 3.1 is known for its innovative approach to computing during an era that marked the transition into more advanced personal computing solutions. Launched as part of IBM's line of personal computers, IBM 3.1 was a notable product in the early 1990s, playing a crucial role in shaping the computing landscape.

One of the key features of IBM 3.1 was its use of the IBM PC DOS operating system, which provided a solid platform for business applications and productivity tools. The inclusion of a graphical user interface (GUI) improved usability compared to its predecessors, allowing users to navigate through tasks with ease.

The system architecture of IBM 3.1 was based on the Intel 80386 microprocessor, which was a leap forward in processing power and efficiency. It offered compatibility with earlier IBM PC models, making it easier for businesses to transition to newer technologies without losing investment in software and peripherals. The introduction of enhanced memory management capabilities allowed users to run multiple applications simultaneously, dramatically improving productivity.

IBM 3.1 also supported advanced technologies such as plug-and-play hardware components, which simplified system configuration and expanded upgrade potential. This feature allowed users to easily add peripherals like printers, modems, and external storage devices without the need for complex installations.

The integrated networking capabilities of IBM 3.1 enabled better connectivity between computers, fostering collaboration among users in office environments. Support for various networking protocols allowed seamless sharing of resources, which was essential in the growing landscape of networked computing.

In terms of storage, IBM 3.1 offered both hard drive options and upgraded floppy disk drives, catering to different user needs. The system supported a variety of software applications including word processors, spreadsheets, and database management systems, solidifying its place as a valuable tool for productivity.

Overall, IBM 3.1 was a groundbreaking personal computer that combined power, user-friendliness, and adaptability. It was a turning point in the evolution of IBM PCs, influencing the design and functionality of future computing products. With its forward-thinking technologies and robust feature set, IBM 3.1 left a lasting legacy in the world of personal computing.
