Welcome
Running the Collector
You run the CICS® IA Collector to look for instances of program commands that might cause resource dependencies or transaction affinities.
Running the Collector for the first time
To run the Collector for the first time, configure the region options using option 2 of the Collector Main Administration Screen before gathering any dependency or affinity data.

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.
- Running the Collector for the first time
  To run the Collector for the first time, configure the region options using option 2 of the Collector Main Administration Screen before gathering any dependency or affinity data.
- Displaying the Collector Main Administration Menu panel
  Use this procedure to display the Collector Main Administration Menu panel.
- Controlling the collection of dependency and affinity data
  Use the menu CIU100 to control the collection of dependency and affinity data.
- Changing the Collector options
  You can control how the Collector operates by changing the options that it uses.
- Managing the Command Flow collection using transaction CINC
  You can manage the Command Flow data collection with the aid of the User Command Flow Utility, which helps you to create new configurations of the Command Flow data collection options, change or define parameters of the configurations that already exist, and display statistics about data collection.
- Operating CICS® IA Collection from the CICS® IA Explorer plug-in
  In CICS® IA 6.1, you can manage data collection not only by using the CINC and CINT transactions, but also by using the CICS IA Explorer plug-in.
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.

Running the Collector for the first time

To run the Collector for the first time, configure the region options using option 2 of the Collector Main Administration Screen before gathering any dependency or affinity data.

See Collector Main Administration Menu panel, CIU000, to:

Specify at least one CICS® region to be monitored
Specify (in further screens) the CICS®, CICSPlex SM, Db2®, MQ, and IMS™ commands to be monitored on that region
Specify (in a further screen) whether dependency or affinity data is to be collected on that region, with some other region-specific options

For more information about setting Collector options, see Changing the Collector options.

If you have migrated the CIUCNTL control file from a previous CICS® IA release, some CICS® regions might already be configured for monitoring.

If you have not migrated the CIUCNTL control file from a previous CICS® IA release (in which case, CICS® IA's global values will already have been set up), before you try to gather any dependency or affinity data, choose the global values menu options to set up CICS® IA's global values. See Collector Global Options Menu panel, CIU300.
