IBM Training for IMS Database Performance and Tuning

Skill Level: Advanced

Modality: CR - Classroom based Trainng or ILO - Instructor Led Online Class

Duration: 5 Day/s

Starting Price: $ - 6,576

Overview:

This is an advanced course for IMS system programmers, Data Base Administrators (DBA) and technical support individuals who are responsible for the performance of IMS Databases.

Learn how to tune Information Management System (IMS) databases._x000D_ _x000D_ Explore the IMS database features that affect performance, such as data set considerations and buffers for Virtual Storage Access Method (VSAM) and Overflow Sequential Access Method (OSAM). Also, practice a method for estimating performance before implementation. Plus, reinforce the skills you have learned with seven machine labs._x000D_ _x000D_ This course is taught in a Web conference medium with live instructor audio, and Internet Web conferenced materials. You have chat type Questions and Answers (Q and A) ability, plus live audio. The course is taught 10:00 a.m. to 12 noon and 1:00 p.m. to 3:00 p.m. Central time for ten work days over a two-week period. Since the class is taught live using Web conferencing methods, you can attend from your home or work. Class durations are approximately one-half day so you can still accommodate daily work responsibilities._x000D_ _x000D_ You will be contacted prior to class start to receive connection information, hardcopy materials, and other relevant information.
