Overview
Client/server is one of the least understood technologies in the IBM midrange arena. Like other technologies of near-mythic proportions, client/server both promises and threatens to change the world of application development as you know it. Your company's management may be asking when you are going to implement client/server, while you are still trying to figure out just what it is. Building AS/400 Client Server Applications will help you sort client/server myth from reality.Michael Otey, a leading client/server authority with extensive practical client/server application development experience, gives you the why, what, and how-to of AS/400 client/server computing, which matches the strengths of the AS/400 with the PC GUIs that users want. This book's clear and easy-to-understand style guides you through all the important aspects of AS/400 client/server applications.
The author covers APPC and TCP/IP communications, as well as the underlying architectures for each of the major AS/400 client/server APIs. You learn to use APPC and the Router API, Remote Command, Data Queues, Distributed Program Calls, and ODBC. Complete source code for several working applications helps you master the nuts and bolts of AS/400 client/server application development. The working examples and utilities can be put to use in your environment immediately. Particularly useful utilities include Communications Monitor, a Windows application that periodically checks the status of an AS/400's communications lines and displays the status in a window; performance Monitor, a Windows application that obtains AS/400 performance data and graphically displays it; and an ODBC benchmark application.
Key features:
- both 16-bit and 32-bit client/server example programs
- techniques for high-performance ODBC applications
- tips for securing ODBC and other client/server applications,
- examples showing how to write AS/400 client server exit programs
