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's new in CICS® IA Version 6.1
CICS® IA Version 6.1 continues to support a wide range of capabilities and fully supports new CICS Transaction Server 6.3. Building on previous releases, CICS IA Version 6.1 contains updates to reflect those commands for which CICS Transaction Server 6.3 has updated the threadsafe status allowing more applications to run without requiring a switch 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 In volatile development environments this data can soon become out of date. If you have out of date data, the CICS IA plug-in might retrieve more data than you need.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 Dependency Reporter
  This section describes how to run the CICS® IA Dependency Reporter. The Dependency Reporter consists of a batch job, CIUJCLRP, that produces reports of the dependencies found by the Collector.
- Running the Affinities Reporter
  The CICS® IA Affinities Reporter can be used to produce reports and definitions.
  - Requesting a report from the Affinities Reporter
    To run the Affinities Reporter against the Affinity database objects, edit and run the CIUAFFRD job. To run the Affinities Reporter against the VSAM affinity data files, edit and run the CIUAFFRP job. Before running either of the jobs, change the values of the parameters listed, as appropriate.
  - Output from the Affinities Reporter
    Each affinity type specified on the CMDGRPS DD statement, for example, CWA or TS is given its own section in the affinity report.
  - Running the affinity report
    Purpose of the report and assumptions to make.
    - Understanding the affinities
      The inter-transaction affinities listed in the report highlight those transactions that have affinities with other transactions.
    - Modifying affinity-transaction-group definitions
      Modifications to consider before providing affinity-transaction-group definitions to the Builder.
  - Compressing affinity data
    If your temporary storage queue names contain a unique counter or a terminal name (termid), a very large number of basic affinity transaction groups might be created for what might seem to be a small number of logical queues.
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.

Running the affinity report

Purpose of the report and assumptions to make.

The affinity report has two main purposes:

To help you understand the affinities present in the CICS® region concerned.
To help you modify the affinity transaction-group-definitions before they are given to the Builder, if such modification is required.

You must be able to investigate whether any application changes could reduce the amount of affinity.

Assume that the affinity information is complete.
Assume that any worsening of affinity relation or affinity lifetime by the Collector does not create too pervasive an affinity, making dynamic routing less effective.
