Summary: IBM IMS Essentials Part 2: IMS Transaction Manager
Review: Course Overview
In IBM IMS Essentials Part 2: Transaction Manager, you learn about IMS Transaction Manager (IMS TM). The architecture and messages in IMS TM are introduced. You learn about the security issues and about protecting system integrity in IMS. In the IMS Transaction Message Processing section, both message and application processing are explained. Finally, Multiple Systems Coupling (MSC) and Intersystem Communication (ISC) are dealt with. This course is current to IMS v.8, but generally applicable to v.7 and beyond.

Learn To
To match dependent region address spaces in the IMS Transaction Manager (TM) architecture with their functions.
To identify functions of IMS system generation (IMSGEN) macros.
To sequence the stages in the flow of a transaction message in a message processing program (MPP).
To identify factors that affect message scheduling.
To identify performance-enhancing message processing region (MPR) options.
To identify functions of Multiple Systems Coupling (MSC).
To identify features and functions of Data Communications Control (DCCTL).
To identify the key aspects of Intersystem Communication (ISC) message routing.

Audience
The primary audience includes users who want a basic understanding of the IMS Database (IMS DB) and IMS Transaction Manager (IMS TM) products. Additionally, data processing individuals who work with an IMS system, whether Database (DB), Database/Data Communications (DB/DC), or Database Control Subsystem (DBCTL). Learners should be able to describe the fundamentals of data processing, including the function of operating systems, access methods and Job Control Language (JCL). These skills can be obtained from on-the-job experience.
