CICS/TS Application Debugging Workshop

This workshop is designed to teach CICS Systems Programmers and Application Programmers how to debug CICS transaction dumps. The course combines formal presentation of theory and the practical analysis of transaction and system dumps. The workshop material is COBOL based.

This course is available for one-company, on-site presentations only.

What you will learn

On successful completion of this course you will be able to:

  • solve development or production problems using CICS formatted dumps
  • specifically solve storage violation problems
  • use CICS supplied transactions in problem solving.

Who Should Attend

CICS systems and application programmers.


No prior experience of programming is necessary, but prior experience of coding CICS application programs or attendance on the course CICS/TS Application Programming Workshop would be an advantage.


3 days

Transaction Dump Analysis

Where do we begin?; PSW & Registers; Solving the ASRA Dump; Working out the Offset; Working out the Source Statement; Finding the Contents of Data Variables; WORKING-STORAGE SECTION: Finding the Working Storage, Once you've found it, now MAP it; Working-Storage Section; LINKAGE SECTION - COBOL; OTHER Abends; Unhandled Exception Conditions (most AEIX/AEXX/AEYX); Finding the Address of Interest; Converting the Address to an Offset in the Source Module; Relating the Offset to a Source Statement; How to find which program LINKed to yours; Program Environment Save Areas (PESAs); How to find which program Dynamic Call called you; Register Save Area Chains (RSAs).

Storage Management

Three Types of Storage Violation; Where to start?; Trace Table Entry Example; Controlling Storage by Subpool; Variable Length Sub-pools; SCE/SCF; Mapping the scope of the damage; Scoping the damage; Transaction Isolation.
