HTTPS_CLIENT_CERT_STATE_OR_PROVINCE

The State or Province from the client certificate’s distinguished name. For example:

Minnesota

HTTPS_KEYSIZE

Returns the number of bits in the session key that is established by SSL after a completed exchange of signals to set up communications between two modems. This value is blank if HTTPS=OFF. For example:

512

Examples of key sizes are Export {40} or {128}.

HTTPS_PORT

If a valid security product is installed and the SSLMode directive is SSLMode=ON, this environment variable contains the SSL port number the server is listening on. For example:

443

CGI Programs and AS/400 Activation Groups

The following section is intended to give a brief overview of AS/400 Activation Groups.

Note: It is very important to become familiar with the details of activation groups prior to developing or porting a CGI application that will use this support.

AS/400 Activation Groups

Program activation is the process that is used to prepare a program to run. The system must activate AS/400 ILE programs before they can be run. Program activation includes the allocation and initialization of static storage for the program in addition to completing the binding of programs to service programs.

Program activation is not an AS/400 unique concept. All modern computer operating systems must perform program initialization and load. What is unique to AS/400 is the concept of Activation Groups. All ILE programs and service programs are activated within an activation group. This substructure contains the resources necessary to run the program. The resources that are contained and are managed with an activation group include:

vStatic and automatic program variables

vDynamic storage

vTemporary data management resources (For example, open files and SQL cursors)

vCertain types of exception handlers and ending procedures

Run-time creation of ILE activation groups is controlled by specifying an activation group attribute when your program or service program is created. The attribute is specified by using the ACTGRP parameter on the CRTPGM or CRTSRVPGM command. The valid options for this attribute include user-named, *NEW, and *CALLER. The following is a brief description of these options:

user-named- A named activation group allows you to manage a collection of ILE programs and ILE service programs as one application. The activation group is created when it is first needed. All programs and service programs that specify the same activation group name use it then.

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.
