Frequently Answers and Questions
What is the purpose of IMS system definition?
IMS system definition describes the system resources (databases, applications, devices, terminals, and links) to IMS when you first install IMS, you apply maintenance to your IMS system, or definition changes are required.
What are some of the key topics covered in this document?
This document covers topics such as defining and tailoring the IMS system, IMS Common Queue Server (CQS), IMS Common Service Layer (CSL), integrated IMS Connect, IMS Transport Manager Subsystem (TMS), and dynamic resource definition (DRD). It also includes descriptions of the IMS macros, procedures, and members of the IMS PROCLIB data set.
How is system definition related to installation?
System definition and JCL preparation are only a part of the total installation process. You should understand the relationship between installation and system definition before defining your system.
