Chapter 6. Communicating with a remote AS/400 system

Using advanced program-to-program communications (APPC), you can configure the AS/400 system to communicate with another AS/400 system. This configuration requires the coordination of configuration parameters and values. Only those configuration prompts and parameters that require coordination on both the AS/400, and the remote AS/400 system are listed. In addition, some of the parameters that are listed may not apply to your particular configuration. See the following topics for more information:

v“Matching AS/400 line description parameters for a remote AS/400 system”

v“Matching AS/400 controller description parameters for a remote AS/400 system” on page 35

v“Matching AS/400 device description parameters for a remote AS/400 system” on page 36

For an example of connecting one AS/400 to another AS/400 system, see “Connecting one AS/400 to another AS/400 system” on page 37.

For more information on AS/400 parameters, see the Communications Configuration book.

Matching AS/400 line description parameters for a remote AS/400 system

You must coordinate communications configuration parameters between local and remote AS/400 systems. These parameters are described in the following table. This table shows those prompts and parameters that must be coordinated when you specify line descriptions for the local and remote AS/400 systems.

To configure a local AS/400 to a remote AS/400:

vSee “Connecting one AS/400 to another AS/400 system” on page 37 for an example of connecting one AS/400 to another AS/400 system.

AS/400 specifications

The IBM AS/400, now known as the IBM iSeries, is a midrange computer system that has been a cornerstone of enterprise computing since its introduction in 1988. Designed to provide a robust platform for business applications, the AS/400 is celebrated for its reliability, scalability, and integrated database capabilities.

One of the key features of the AS/400 is its Integrated Operating Environment, which blends hardware and software resources seamlessly. This integration allows businesses to execute diverse workloads, ranging from traditional applications to modern web-based services, all on a single platform. The operating system, OS/400 (now IBM i), offers a rich set of APIs and tools for developers, simplifying application development and management.

Another standout characteristic of the AS/400 is its built-in database, DB2 for i. This powerful relational database management system allows for efficient data handling and provides advanced features such as support for SQL, XML, and JSON, making it easier for businesses to manage their data and integrate it with other systems. The database's tight integration with the operating system enables high performance and security.

In terms of scalability, the AS/400 can accommodate small businesses as well as large enterprises, with the ability to support hundreds of users simultaneously. Its architecture allows for easy upgrades in hardware, meaning that organizations can scale their systems without replacing the entire infrastructure.

Security is another critical attribute of the AS/400. With a sophisticated security model, it offers built-in user authentication, access control, encryption, and auditing capabilities to protect data and applications from unauthorized access.

The AS/400 also supports multiple programming languages, including RPG, COBOL, Java, and PHP, giving organizations the flexibility to choose the development tools that best fit their needs. This diversity helps maintain legacy applications while also developing new ones that leverage modern technologies.

Moreover, the platform supports both traditional green-screen interfaces and modern graphical user interfaces, allowing organizations to transition smoothly into contemporary user experience paradigms.

Overall, the IBM AS/400 stands out as a resilient, flexible, and secure computing platform that enables organizations to effectively manage their business operations, streamline processes, and adapt to changing market demands. Its unique combination of integrated features and capabilities ensures that it remains relevant in today's fast-paced technology landscape.
