About OS/400 Network File System Support (SC41-5714)

The purpose of this book is to explain what the Network File System is, what it does, and how it works on AS/400. The book shows real-world examples of how you can use NFS to create a secure, useful integrated ®le system network. The intended audiences for this book are:

vSystem administrators developing a distributed network using the Network File System.

vUsers or programmers working with the Network File System

Chapters one and two introduce NFS by giving background and conceptual information on its protocol, components, and architecture. This is background information for users who understand how AS/400 works, but do not understand NFS.

The rest of the book (chapters three through nine) shows detailed examples of what NFS can do and how you can best use it. The overall discussion topic of this book is how to construct a secure, user-friendly distributed namespace. Included are in-depth examples and information regarding mounting, exporting, and the following topics:

vHow NFS functions in the client/server relationship

vNFS exceptions for AS/400 ®le systems

vNFS startup, shutdown, and recovery

vFile locking

vNew integrated ®le system error conditions and how NFS affects them

vTroubleshooting procedures for NFS security considerations

It is assumed that the reader has experience with AS/400 client/server model, though not necessarily with the Network File System.

Who should read this book

This book is for AS/400 users, programmers, and administrators who want to know about the Network File System on AS/400. This book contains:

vBackground theory and concepts regarding NFS and how it functions

vExamples of commands, AS/400 displays, and other operations you can use with

NFS

vTechniques on how to construct a secure, efficient namespace with NFS

AS/400 Operations Navigator

AS/400 Operations Navigator is a powerful graphical interface for Windows clients. With AS/400 Operations Navigator, you can manage and administer your AS/400 systems from your Windows desktop.

You can use Operations Navigator to manage communications, printing, database, security, and other system operations. Operations Navigator includes Management Central for managing multiple AS/400 systems centrally.

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.
