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.<br><br> 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.<br> 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.<br><br>

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

  • describe the architecture of IMS batch and online systems
  • analyse 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
