Preface

This information describes the IBM® CICS® Interdependency Analyzer. It explains what the program does and how to set up and run its various components.

What this information is about

CICS Interdependency Analyzer (CICS IA) is a run time tool for use with CICS Transaction Server for z/OS®. It has three main purposes:
  1. To identify the sets of resources used by individual CICS transactions, and their relationships to other resources.
    CICS IA enables you to understand the characteristics of your application set, that is:
    • what a CICS region contains,
    • which resources a transaction needs to be able to run,
    • which programs use which resources,
    • which resources are no longer used.
    Understanding these characteristics improves your ability to maintain, enhance, modify, or redistribute your applications.

    CICS IA captures interdependency information while CICS is running and stores it in VSAM files, from which detailed reports can be produced. The VSAM files are used to load DB2® databases, on which SQL queries can be performed.

  2. To collect and analyze data about transaction affinities. Transaction affinities require particular groups of transactions to be run either in the same CICS region, or in a particular region.

    This function is useful in a dynamic routing environment, you might need to know of any restrictions that prevent particular transactions being routed to particular application-owning regions (AORs) or that require particular transactions to be routed to particular AORs.

    CICS IA loads the affinity data into DB2 databases, on which SQL queries can be performed and from which detailed reports can be produced.

  3. To collect and analyze Command Flow data for a given transaction or terminal.

    The Command Flow feature records all CICS, DB2, MQ and IMS™ commands issued in a chronological order. This allows you to understand the different paths a given transaction can go. You can run your own Command Flow captures and view it through the IA Explorer plug-in.
