Summary -

In this page, we describes about audiences, objective, prerequisites and the topics that are covered as part of tutorial.

Introduction -

In traditional batch system, multiple processes/tasks can't able to run parallelly while using the same set of resources. For example, if two tasks are submitted parallelly that are using same set of resources like files, tables etc, the task that got the exclusive control on the resources starts get executing first and the other task need to be in wait status until the first one completed to get the control on the resources.

So the main disadvantage is parallel processing and the other disadvantage is the processing results are not instant. To overcome the above disadvantages, IBM had launched the CICS in late 1960’s.

Audiences -

In this tutorial, all the topics are covered with in-depth information and can understandable by anyone.

Objective -

The tutorial is intended for the readers with no previous programming or computer science experience as well as for those with some computing background.

Prerequisites -

Need to learn COBOL if learning the CICS for coding in COBOL programs. Learn COBOL tutorial at COBOL Tutorial .

There are no prerequisites to learn CICS if learning the CICS only to know how the online processing in mainframe system. Having the computation background will be an advantage in understanding the concepts a bit easy. Without having computation background, it is a bit time taking to understand the concepts and need to go through the topic more than once to understand clearly.
