Matching AS/400 controller description parameters for a host system

You must match host system communications configuration parameters with AS/400 values. A description of the AS/400 values are in the following table. For information about configuring host systems, see the manuals VTAM Installation and Resource Definition, SC23-0111, and Network Control Program Resource Definition Reference, SC30-3254.

You can specify some host system parameters on multiple definition statements, such as the GROUP, LINE, PU, and LU. The following table lists only the lowest level definition statement that is used by the host system.

To configure an AS/400 to a host system:

vSee “Examples: Connecting AS/400 to a host system” on page 26 for an example of connecting an AS/400 to a host system.

vUse the following table for the controller description parameter.

 

AS/400

Host Definition

 

AS/400 Prompt

Parameter

Statement

Host Parameter

 

 

 

 

Adjacent link station

ADJLNKSTN

PU

name

 

 

 

AS/400 adjacent link station name must match the

 

 

 

name assigned to the PU macro instruction in the host

 

 

 

system switched major node definition. This match is

 

 

 

required if AS/400 host controller description specifies

 

 

 

RMTCPNAME(*ANY), SWITCHED(*YES) or

 

 

 

SNBU(*YES), and LINKTYPE is *SDLC or *IDLC.

 

 

 

This parameter should be specified only if the host

 

 

 

system is running VTAM Version 4 Release 1 or later

 

 

 

and NCP Version 6 Release 2 or later.

 

 

 

 

LAN remote adapter

ADPTADR

LINE

LOCADD

address

 

 

Values specified for each system must match. If

 

 

 

 

 

 

LOCADD is specified, ECLTYPE=PHYSICAL must also

 

 

 

be specified on the GROUP definition statement.

 

 

 

 

 

 

PORT

MACADDR

 

 

 

For 9370/LAN only, the AS/400 controller description

 

 

 

ADPTADR must match the host MACADDR parameter.

 

 

 

MACADDR can be coded as an 8- or 12-digit

 

 

 

hexadecimal number; the 8-digit variation assumes 4000

 

 

 

in the first four positions (4000xxxxxxxx).

 

 

 

 

Destination service

DSAP

PORT

SAPADDR

access point

 

 

For 9370/LAN only, the AS/400 controller description

 

 

 

 

 

 

DSAP must match the host SAPADDR parameter.

 

 

 

The SAPADDR parameter is a decimal value (4-252);

 

 

 

the AS/400 value is specified as a 2-digit hexadecimal

 

 

 

number.

 

 

 

 

Local exchange

LCLEXCHID

PU

IDBLK, IDNUM

identifier

 

 

For parallel connections only. Required if the AS/400

 

 

 

 

 

 

system specifies RMTCPNAME(*ANY),

 

 

 

SWITCHED(*YES), and LINKTYPE is *SDLC or *IDLC.

 

 

 

The LCLEXCHID specified must match the values

 

 

 

specified in the switched major node definition PU

 

 

 

macro instruction.

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.
