What's new in CICS® IA Version 6.3
CICS® IA Version 6.3 maintains broad functionality and provides full support for the new CICS Transaction Server 6.3. Building on previous releases, it includes updates for commands whose threadsafe status has been enhanced in CICS Transaction Server 6.3, enabling more applications to run without switching to QR TCB mode
Overview of the CICS® Interdependency Analyzer
This section gives an overview of the CICS® Interdependency Analyzer (CICS IA), and describes its components.
Getting Started with the CICS® IA plug-in for CICS Explorer®
The CICS® Interdependency Analyzer plug-in for CICS Explorer® provides an Eclipse-based interface to analyze your CICS IA data. It also provides cheat sheets that guide you through the steps required to configure and install CICS IA. It is recommended that you download the CICS IA plug-in and follow the steps in the cheat sheets.
Configuring CICS® IA
This section describes what you need to do before you can use CICS® IA.
Running the Collector
You run the CICS® IA Collector to look for instances of program commands that might cause resource dependencies or transaction affinities.
Updating the Dependency and Affinity database objects
The Dependency database objects contain accumulated data about your applications and the resources that they use. Update the database objects regularly to add new information recorded by the Collector in the VSAM dependency files.
Managing your CICS® IA data
With each new release CICS® IA captures more data. In volatile development environments this data can soon become out of date. If you have out of date data, the CICS IA plug-in might retrieve more data than you need. The presence of unwanted data might impede your analysis and provide confusing results.
The CICS® IA UDB database
CICS® IA provides jobs to unload CICS IA data into CSV files. These files can be used to populate the IBM® supported UDB databases.
Running the Reporter
Running the Program Threadsafe report
The threadsafe report can be run from the CICS IA Explorer plug-in or as a batch job using the sample CIUJTSQ2 that can be found in SCIUSAMP.CICS. The report runs the Db2® stored procedure CIUSPTSR.
Running the Load Module Scanner
The Load Module Scanner scans load modules for instances of program commands that could cause resource dependencies or transaction affinities.
Running the CSECT Scanner
The CICS® IA CSECT Scanner scans load modules for information that can be used to identify the version of each CSECT.
Running the Builder
The CICS® IA Builder runs as a batch job to build affinity-transaction-group definitions suitable for input to the CICS system management product, CICSPlex SM.
Running the sample Db2® query
This section describes how to run the sample CICS® IA batch query job CIUJSAMP.
Solving problems
This section helps you to isolate and determine the cause of CICS® IA problems.

The structure of the CICS® IA database
Messages and codes
This section describes the messages that the Collector, Query interface, Dependency Reporter, Affinities Reporter, Load Module Scanner, CSECT Scanner, and Builder can issue, and the transaction abend codes that the Collector can produce.
CICS® IA space considerations
CICS® IA security
CICS® IA External Interfaces
The Appendix describes available Stored Procedures and Command Flow user exit.
Collecting dynamic COBOL calls
CICS® IA detects dynamic COBOL calls, which are collected by the Dependency and Command Flow Data collectors.

Preface

This information describes the IBM® CICS® Interdependency Analyzer for z/OS®. 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:

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 IBM® Db2® databases, on which SQL queries can be performed.
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.
To collect and analyze Command Flow data for a given transaction or terminal.
The Command Flow feature records all CICS®, IBM® 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.
