Threadsafe: Yes

Use the QzhbCreateGroupList API to create a new empty group file, and return a handle to that empty in-memory version of the file. Normally this API would be followed by calls to the QzhbAddGroupToList and QzhbAddUserToGroup APIs, followed by the QzhbCloseGroupList API to write group information out.

Upon successful completion of this API, a new group list handle is returned. This is a handle much like the one returned by the QzhbOpenGroupList API against an already existing file, with a writelock argument of 1 (TRUE). After a call to the QzhbCreateGroupList API the new file is left open for write access and the QzhbCloseGroupList API can be invoked with a write argument of 1. For more details about the writelock argument, see “Read a Group File into Memory (QzhbOpenGroupList) API” on page 65.

Authorities and locks

To invoke this API, the user must have the following authorities:

v*X authority to each directory in the path of the specified group file

v*WX authority to the last directory in the path that will contain the group file path

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.
