GATEWAY_INTERFACE

Contains the version of CGI that the server is using. For example:

CGI/1.1

HTTP_ACCEPT

Contains the list of MIME types the browser accepts. For example:

text/html

HTTP_USER_AGENT

Contains the name of your browser (web client). It includes the name and version of the browser, requests that are made through a proxy, and other information. For example:

Netscape Navigator dll /v3.0

IBM_CCSID_VALUE

The CCSID under which the current server job is running.

PATH_INFO

Contains the additional path information as sent by the web browser. For example:

/ballyhoo

PATH_TRANSLATED

Contains the decoded or translated version of the path information that is contained in PATH_INFO, which takes the path and does any virtual-to-physical mapping to it. For example:

/wwwhome/ballyhoo

QUERY_STRING

When information is sent using a method of GET, this variable contains the information in a query that follows the ?. The string is coded in the standard URL format of changing spaces to “+” and encoding special characters with “%xx” hexadecimal encoding. The CGI program must decode this information. For example:

NAME=Eugene+T%2E+Fox&ADDR=etfox%7Cibm.net&INTEREST=xyz

REMOTE_ADDR

Contains the IP address of the remote host (web browser) that is making the request, if available. For example:

9.23.06.8

REMOTE_HOST

Contains the host name of the web browser that is making the request, if available. For example:

raleigh.ibm.com

REMOTE_IDENT

Contains the user ID of the remote user. For example:

Jillx

REMOTE_USER

If you have a protected script and the server supports client authentication, this environment variable contains the user name that is passed for authentication. For example:

Jill

REQUEST_METHOD

Contains the method (as specified with the METHOD attribute in an HTML form) that is used to send the request. For example:

GET or POST

AS/400E specifications

The IBM AS/400E, now more commonly known as IBM i, is a robust and versatile midrange server that has been designed to provide a comprehensive computing solution for businesses of all sizes. First introduced in the late 1980s, the AS/400 series has undergone multiple enhancements and rebranding, with the AS/400E being one of the notable iterations. This powerful platform is closely associated with IBM's commitment to reliability, scalability, and integrated business solutions.

One of the main features of the AS/400E is its highly integrated architecture that combines hardware and software into a cohesive system. This integration allows for seamless operations, reducing the complexity typically associated with managing disparate systems. The system is powered by IBM's proprietary OS/400 operating system, which has evolved into IBM i, featuring advanced capabilities like object-oriented programming, integrated database management, and security features that are essential for enterprise environments.

A key characteristic of the AS/400E is its robust database support, primarily through the use of DB2 for i. This integrated database management system enables efficient data handling and retrieval, facilitating real-time business analytics and reporting. Furthermore, the platform supports a variety of programming languages, including RPG, COBOL, and Java, making it flexible for developers who require diverse tools for application development.

The AS/400E is also known for its exceptional reliability and uptime, making it a preferred choice for critical business applications in industries such as finance, healthcare, and manufacturing. This reliability is backed by advanced error detection and correction mechanisms, as well as redundancy features that help prevent data loss and minimize downtime.

In terms of scalability, the AS/400E can effortlessly expand to accommodate growing business demands. Organizations can increase processing power by adding more resources without significant disruption. This scalability, combined with the system’s built-in virtualization capabilities, allows businesses to optimize resource usage and streamline operations.

Security is another defining feature of the AS/400E. The platform incorporates various layers of security measures, including user authentication, encryption, and comprehensive auditing capabilities, ensuring that sensitive business data is protected against unauthorized access.

Overall, the IBM AS/400E remains a powerful tool in the enterprise computing landscape, providing businesses with an integrated, reliable, and secure solution for their technological needs. Its enduring popularity is a testament to its capability to evolve with changing business requirements while maintaining its core attributes of high performance and stability.
