Interface Modernization - CGI Example

This document discusses modernizing applications on IBM i systems to avoid interactive 5250 workloads. It provides alternatives for end users, administrators, and developers such as web-based applications, report tools, administration tools, and development tools like Java and PHP. The demonstration program allows remote users to run inventory reports from a web browser rather than a 5250 application.
Interface Modernization - CGI Example
- 1. Simple Application Modernization Demonstration On IBM System i™ and eServer™ models, the method used to determine the processing capability that is available for 5250 OLTPi tasks depends on the edition type of the server. Using a Standard edition server effectively means finding alternate ways to do work that uses green-screen functions now. The basic strategy is to avoid interactive CPW workloads (5250 OLTP or 'green-screen' work) by using alternate methods of access for users, administrators and developers on the system. For end users this means: • Reviewing 5250 work that can be avoided through better configuration, management and automation • Using alternative software such as web aware applications with system screen support • Using alternate report tools to traditional 5250 tools, such as Query/400 -- there are a number that cost about the same price or less For system administration this means: • Reviewing system administration tasks that can be avoided through better configuration, management and automation • Using alternative tools such as i5 Navigator and System Director for most administration tasks For developers this means: • Reviewing development work that can be avoided or reduced through better tools and automation • Using alternative tools such as WDSC Fortunately, there are many development tools available (for free and/or for fee) to modernize your applications depending on your business requirements and shop standards including: • Java and JT Open • Microsoft ADO.Net • PHP and mySQL • CGI Programming • Net.Data for i5/OS This simple online demonstration is built with open sourced code that was developed at IBM Rochester by Mel Rothman and others. It is an early prototype that runs on my development model 170 system and does NOT access any client data. The production version allows remote users who don’t necessarily access 5250 applications frequently to run their inventory reports on the corporate headquarters server from a web browser and receive them as a link to a pdf or excel file via email.

Examples of 5250 OLTP tasks include the following: • Any form of 5250 emulation, including Hardware Management Console (HMC) 5250, RUMBA/400, PC/400 workstation feature, Binary Synchronous Communication (BSC) 3270 emulation, MochaSoft TN 5250 etc. • 5250 Telnet or 5250 Display Station Pass-Through (DSPT) workstations, 5250/HTML Workstation Gateway, etc. Page: 3
