CHGNFSEXP OPTIONS(©-I -O RO,ANON=199,ACCESS=Prof:1.234.5.6©)

DIR(©/engdata/mech©)

HOSTOPT((TULAB1 850 850))

This command exports the directory tree under the path name /engdata/mech as read-only. This command allows only two clients to mount this directory tree. It takes advantage of the positional parameters, which do not require keywords. It uses the HOSTOPT parameter to specify code pages for the host TULAB1.

Example 3: Exporting a directory to many netgroups.

CHGNFSEXP OPTIONS(©-I -O ACCESS=students:LabSystems:Profs, ANON=-1©)

DIR(©/home©)

This command exports the directory tree under the path name /home to three netgroups de®ned in the/etc/netgroup ®le:

 

1.

students

 

2.

LabSystems

3.

Profs

 

However, not all members of these netgroups have read/write access to the /home

 

directory. Individual and group permissions still apply to the path. This command

 

also speci®esANON=-1, which does not allow access to this system by anonymous

 

users.

 

Example 4: Forcing read-only permissions on an export.

 

CHGNFSEXP OPTIONS(©-I -O RO, RW=students:LabSystems, ANON=-1,

 

 

ACCESS=Profs:LabSystems:students©)

 

 

DIR(©/classes©)

 

This command exports the directory tree under the path name /classes to the

netgroups Profs, LabSystems, and students. However, only students and

 

LabSystems have read/write authority to the exported tree. This command also

speci®esANON=-1, which does not allow access to this system by anonymous users.

Exporting from Operations Navigator

OS/400 Version 4 Release 3 added a good deal of support to Operations Navigator

to allow better centralized server management. The integrated GUI interface makes

it possible to easily perform common NFS server functions like exporting. Use the

following steps to export from Operations Navigator:

1. Find the directory or folder you wish to export under the ®le systems folder in

 

the left panel of the Operations Navigator window. The following ®gure shows

 

an example of the QOpenSys ®le contents displayed in the right panel of the

 

Operations Navigator window.

2. Right-click on the folder to display the pop-up menu.

 

The following ®gure shows an example of the Operations Navigator interface:

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.
