Overview:

This intermediate course is for ndividuals interested in the performance of the IMS Database System.

Learn how to tune Information Management System (IMS) databases for use in IMS/Batch, IMS/Data Communications (DC), CICS-Local-Data Language One (DL/I), and Data Base Control (DBCTL) environments._x000D_ _x000D_ Explore the IMS database features that affect performance such as data set considerations and buffers for VSAM and OSAM. You will also practice a method for estimating performance before implementation. Plus, you will reinforce the skills you have learned with seven machine labs._x000D_ _x000D_ IACET Continuing Education Units: 4.0
