AS/400 Prompt

Parameter

Statement

Host Parameter

 

 

 

 

Local adapter address

ADPTADR

PATH

DIALNO

 

 

 

Host DIALNO parameter is a concatenation of:

 

 

 

SSAP/DSAP/remote-adapter-address.

 

 

 

AS/400 CRTLINTRN command ADPTADR value must

 

 

 

match the remote-adapter-addressportion of the host

 

 

 

DIALNO parameter. The DSAP portion of the DIALNO

 

 

 

parameter must correspond to the SSAP value

 

 

 

specified on the AS/400 controller description.

 

 

 

 

 

 

PU

MACADDR

 

 

 

For 9370/LAN only, the AS/400 line 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).

 

 

 

 

Connection type

CNN

GROUP

DIAL

 

 

 

If the AS/400 line description CNN parameter is

 

 

 

*SWTPP or *SHM, DIAL=YES must be specified for the

 

 

 

host system; if CNN is *MP or *NONSWTPP, DIAL=NO

 

 

 

must be specified.

 

 

 

If CNN(*MP) is specified, the SERVICE

 

 

 

macroinstruction must be used to specify the sequence

 

 

 

in which stations are served.

 

 

 

 

Exchange identifier

EXCHID

PU

IDBLK, IDNUM

 

 

 

The AS/400 block number (digits 1-3 of the EXCHID) is

 

 

 

always 056. The remaining 5 digits (based on the

 

 

 

system serial number if *SYSGEN is used) are

 

 

 

specified in the IDNUM parameter.

 

 

 

 

Line speed

LINESPEED

LINE

SPEED

 

 

 

Line speeds specified for each system must match.

 

 

 

 

Maximum frame size

MAXFRAME

PU

MAXDATA

 

 

 

Values specified for each system must match.

 

 

 

 

NRZI data encoding

NRZI

LINE

NRZI

 

 

 

Values specified for each system must match.

 

 

 

 

Station address

STNADR

PU

ADDR

 

 

 

AS/400 system station address must be unique within

 

 

 

host PU definitions. (Ignored within 9370/LAN

 

 

 

environment.)

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.
