IMS Essentials

July 22 - July 25

$3600
This course offers a comprehensive introduction to IMS for all those new to the IMS environment. It provides ideal cross-training for application support specialists from disciplines such as CICS, COBOL, JAVA, or DB2.
The course introduces and explains all areas of IMS databases in both the Batch and Online environments, including data access using the DL/I Language Interface and the maintenance of data integrity using the DBRC feature. Written exercises reinforce the formal tuition sessions. These include the analysis of sample applications and use of the procedures and utilities required to recover from various application and system failures.

The next step

For all DBAs, systems programmers and technical support personnel the logical follow-on to this is the five-day IMS/DB & IMS/TM for Technical Support course.

What do I need for “Virtual Classroom Environment”?
  • Webcam.
  • Headphones with a microphone.
  • Sufficient bandwidth, at least 1.5 Mb/s in each direction.

Objectives

On successful completion of this course you will be able to:

  • Describe the architecture of IMS batch and online systems
  • Analyze database and communication calls
  • Identify appropriate logical and physical database design features
  • Describe the structure of secondary indexes and logical relationships
  • Use IMS utilities to backup, restore, and reorganize the database
  • Discuss the facilities available in IMS to provide data integrity and system availability.
  • Trace the flow of a transaction through an IMS system

Who Should Attend?

All those working in IMS Applications and Database Development, or any systems and operations personnel who require an understanding of the IMS environment.

Prerequisites

A general understanding of the IBM enterprise server (mainframe) computing environment and an appreciation of application development concepts is assumed.
