IMS System Administration

 LENGTH OF COURSE:
 5 Days

DESCRIPTION: This course provides students with the basic knowledge of the interactions of all of the IMS components and the definition options to create the required environment. Discussed are topics dealing with problem determination and correction, performance and tuning, and the interactions with other OS/390 subsystems. The goal is to help the attendee administer an IMS environment.

PREREQUISITES: Knowledge of IMS facilities including application programming DL/I calls and data base structures, basic MFS skills, OS/390 facilities including JCL/procs and symbolic parameters, Assembler macro conventions, and utilities.

INSTRUCTION TECHNIQUES: A combination of Lecture and Demonstrations.

AUDIENCE

This course is designed for IMS Systems personnel who have responsibilities for or participate in the IMS system definition process, IMS and application systems implementation, problem determination, and the overall IMS tuning effort.
