Objectives

During this course participants become familiar with the general principles of the IMS system. Both the database system (IMS/DB) and the transaction manager (IMS/TM) are treated.

The main objective of this course is to offer -in particularly for the database part- an insight into the link between physical structures and its logical view of applications. An overview of the possibilities of such applications is given.

The description of the TP-monitor gives an insight into message processing in the IMS system. The different ways of building an application (conversational versus non-conversational) are also treated.

Main topics

  • Situation of IMS/DB and IMS/TM
  • The database management system (IMS/DB):
  • hierarchical structures
  • physical organisations of databases
  • the most important control blocks (DBD and PSB)
  • interrogation language proceeding from programmes
  • secondary indexes and logical relations
  • The data communication system (IMS/TM):
  • tasks of the DC monitor
  • internal set-up
  • interrogation language proceeding from programmes
  • conversational versus non-conversational applications
  • modular set-up
  • synchronisation and security
