Using the EBCDIC_JCD mode: The EBCDIC_JCD mode determines what character set is being used by the browser for a given request. This mode is also used to automatically adjust the ASCII/EBCDIC code conversions used by the web server as the request is processed.

After auto detection, the %%EBCDIC_JCD%% mode converts the stdin and QUERY_STRING data from the detected network CCSID into the correct EBCDIC CCSID for Japanese. The default conversions configured for the server instance are overridden. The DefaultFsCCSID directive or the -fsccsid startup parameter specifies the default conversions. The startup FsCCSID must be a Japanese CCSID (5026 or 5035).

The possible detected network code page is Shift JIS, eucJP, and ISO-2022-JP. The following are the associated CCSIDs for each code page:

Shift JIS

(See note 1)

=========

 

CCSID 932: IBM PC (old JIS sequence, OS/2 J3.X/4.0, IBM Windows J3.1)

CCSID 942: IBM PC (old JIS sequence, OS/2 J3.X/4.0)

CCSID 943: MS Shift JIS (new JIS sequence, OS/2 J4.0 MS Windows J3.1/95/NT)

eucJP

=====

CCSID 5050: Extended UNIX Code (Japanese)

ISO-2022-JP (See note 2)

===========

CCSID 5052: Subset of RFC 1468 ISO-2022-JP (JIS X 0201 Roman and JIS X 0208-1983) plus JIS X 0201 Katakana.

CCSID 5054: Subset of RFC 1468 ISO-20220JP (ASCII and JIS X 0208-1983) plus JIS X 0201 Katakana.

The detected network CCSID is available to the CGI program. The CCSID is stored in the CGI_ASCII_CCSID environment variable. When JCD can not detect, the default code conversion is done as configured (between NetCCSID and FsCCSID). (See note 3.)

Since the code page of Stdin and QUERY_STRING are encoded according to the web client’s outbound code page, we recommend using the following configuration value combinations when you use the %%EBCDIC_JCD%% mode.

Startup FsCCSID

 

Startup NetCCSID

Description

---------------

 

----------------

----------------------

5026/5035 (See note 4)

<->

943

Default:

MS Shift JIS

5026/5035 (See note 4)

<->

942

Default:

IBM PC

5026/5035 (See note 4)

<->

5052/5054

Default: ISO-2022-JP

Using CCSID 5050(eucJP) for the startup NetCCSID, is not recommended. When 5050 is specified for the startup NetCCSID, the default code conversion is done between FsCCSID and 5050. This means that if JCD cannot detect a code page, JCD returns 5050 as the default network CCSID. Most browser’s use a default outbound code page of Shift JIS or ISO-2022-JP, not eucJP.

If the web client sends a charset tag, JCD gives priority to the charset tag. Stdout function is the same. If the charset/ccsid tag is specified in the Content-Type field, stdout gives priority to charset/ccsid tag. Stdout also ignores the JCD detected network CCSID. (See note 5.)

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.
