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 6.3
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 In volatile development environments this data can soon become out of date. If you have out of date data, the CICS IA plug-in might retrieve more data than you need.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
- The structure of the Dependency database objects
  This section describes the tables and views defined in the Dependency database.
  - Dependency base tables
    The Dependency base tables are defined in the database objects. You can write your own SQL applications to query the tables; these applications must use native SQL queries.
  - Dependency facilitating tables
    Dependency facilitating tables are used by CICS® IA to gather information that is required for CICS IA processes.
  - Threadsafe table
    CICS® commands that are threadsafe in at least one of the supported CICS TS releases are listed. Use the information in the table when reporting which CICS commands used by a program are threadsafe. Load by running job CIUTSLOD in the SCIUSAMP.Db2 data set.
  - Dependency views
    The dependency views show gathered data about dependency.
    - Application dependency views
      The application dependency views show gathered data about any CICS®, Db2®, IBM MQ, and IMS® application dependency.
    - Transaction dependency views
      The transaction dependency views show data that is gathered about any CICS®, IBM® Db2®, IBM MQ, and IMS® application dependency.
    - Web service dependency views
      The web service dependency views show data that is gathered about any CICS®, Db2®, IBM MQ, and IMS® application dependency.
- The structure of the Affinity objects
  This section describes the tables and views defined in the set of Affinity database objects.
- The structure of the Load Module Scanner objects
  This section describes the tables and views defined in the Load Module Scanner database objects.
- The structure of the CSECT Scanner objects
  This section describes the tables and views defined in the CSECT Scanner database.
- The structure of the CICS® regions objects
  This section describes the structure of the CICS® regions objects.
- The structure for the Detailed resource objects
  This section describes the structure for the Detailed resource objects.
- The structure of the CICS® IA plug-in for IBM® CICS Explorer™ resource objects
  This section describes the CIU_RESOURCE table. This table is used by the CICS® IA plug-in to improve performance and combine resource tables.
- The structure of the Version objects
  This section describes the CIU_VERSION table. This table is used by the CICS IA plug-in for CICS® Explorer to synchronize the CICS IA plug-in version being used and the base IA database objects.
- The structure of the Command Flow table objects
  This section describes the Command Flow base table that contains records for each command that is issued by the transactions. You can write your own SQL applications to query the table; these applications must use native SQL to write the queries.
- The Structure of the Program Flows table objects
  This section describes the structure of two CICS IA tables that are used only to generate the program flows report in the CICS IA plug-in for the CICS Explorer.
- Type and Function mapping for monitored commands
  Learn about the correspondence between resource type and command function for the monitored CICS® commands.
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.

Dependency views

The dependency views show gathered data about dependency.

V_CIU_DB2_RES

This view is a simple Db2® equi-join of CIU_DB2_DATA and SYSIBM.SYSPACKSTMT, using the PROGRAM, SECTION, and STATEMENT fields in CIU_DB2_DATA, and the NAME, SECTNO, and STMTNO fields in SYSIBM.SYSPACKSTMT. You can use it to display the Db2® commands, and therefore the Db2® resources, used by a CICS® program.

Table 1. View V_CIU_DB2_RES
Column	Type	Description
APPLID	CHAR(8)	CICS® applid.
HOMESYSID	CHAR(4)	SYSID of local region.
Db2ID	CHAR(4)	Db2® subsystem ID.
TRANSID	CHAR(4)	CICS® Transaction ID.
PROGRAM	CHAR(8)	CICS® program name.
PLAN	CHAR(8)	Db2® plan ID.
SECTNO	SMALLINT	The section number, in the source code of the CICS® program, at which the Db2® command is issued .
STMTNO	SMALLINT	The precompiler statement number, in the source code of the CICS® program, at which the Db2® command is issued.
STMT	CHAR(*)	The Db2® command (statement) in SYSIBM.SYSPACKSTMT.

V_CIU_DB2_RES2

This view is the same as V_CIU_DB2_RES, except that it joins CIU_DB2_DATA with SYSIBM.SYSSTMT, rather than SYSIBM.SYSPACKSTMT.
