Quick facts

Overview of ACMS

ACMS is a TP monitor that provides a development, run-time, and application management system for TP applications. It is designed for a modular, flexible development style and efficient use of system resources in large on-line applications. ACMS provides the environment for customers to create and manage transaction processing systems that provide predictable response time for users.

Developing ACMS applications

ACMS combines a structured, high-level application definition language and utilities to build, manage, and control complex applications. The modular nature of ACMS applications makes them more efficient to develop and run, and easier to maintain than traditional applications programs. ACMS applications can be modified by changing individual components, rather than rewriting the entire application.

ACMS is part of an integrated application development environment that includes presentation services, transaction and database management, programming languages, and tools, as shown in the ACMS Application Development Model below.

Application Development Model

The ACMS TP monitor makes client/server TP applications easy to develop, reliable to use, and scalable to meet the needs of growing businesses.

» TP Desktop Connector

TP Desktop Connector provides client access for the runtime server environment for Microsoft Windows connectivity. For additional information regarding TP Desktop Connector, please refer to SPD 34.81.xx.
