Introduction to the IMS system

This topic outlines the administrative activities for an IMS system. It also introduces the concepts that are central to administering an IMS system.

Overview of administrative activities
To administer an online IMS system, you must design an IMS online system, establish operating procedures that meet application requirements, maintain a production system that is responsive to end users, and integrate new applications or major design changes into the current system.
IMS environments and configurations
IMS contains two major components that can be used together or separately: the IMS Database Manager (DB) and the IMS Transaction Manager (TM). When you use them together, they constitute the DB⁄DC environment.
