Editing stream ®les by using a PC based editor

 

The second method to edit the netgroup ®le is by using a PC-based editor. If you

 

want to use a PC-based editor, you need access to the /etc directory on the

 

AS/400. Use one of the following to accomplish this:

 

v

Operations Navigator

 

v

File Transfer Protocol (FTP)

 

If you are using Operations Navigator, you must have direct access to the /etc

 

directory. Therefore, your PC-based editor edits the ®le on the AS/400 system.

 

Using FTP to edit a stream ®le, perform the following steps:

1.

Transfer the ®le to your PC by using FTP.

2.

Perform your desired changes by using the editor of your choice.

3.

Transfer the ®le back to the/etc directory by using FTP.

Editing stream ®les by using a UNIX editor via NFS

 

A third way to edit stream ®les on the AS/400 system is using a UNIX editor via the

 

Network File System. In order to do this, perform the following steps:

1.

Export the /etc directory on the NFS server by using the EXPORTFS

 

 

command.

2.

Mount the /etc/ directory to your UNIX system by using the MOUNT command.

3.

Change into the /etc directory by using the Change Directory (CD) command.

4.

Edit the desired ®le by using the VI editor or an editor of your choice.

 

 

 

/etc/exports File

 

 

 

This ®le contains the default exports for the NFS server. This ®le is processed whenever the STRNFSSVR command is used with the *ALL parameter. When created by the system, this ®le is written in ASCII characters.

Formatting Entries in the /etc/exports File

There are several restrictions on the format of path names in the /etc/exports ®le. They are:

1.All entries are ended by the end of a line.

2.The continuation character '\' can be used to extend one entry across multiple lines when it is the last character in the line.

3.All path names must be absolute, beginning at ªrootº (/).

4.The ®rst character must be a slash (/)

5.There can be no spaces within the path name

6.Elements of a path must be separated by the '/' character

7.Each path element cannot be longer than 255 characters

8.No hexadecimal characters are allowed

9.No control-characters are allowed (this includes any characters below ASCII x020).

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.
