CICS/TS TRANSACTION DEBUGGING WITH ENTERPRISE COBOL V6.2

Course:   CICSD67
Duration:   4 Days
Level:   I
On our website at:   http://www.verhoef-training.com/courses/CICSD67.html
 
Course Summary

This CICS/TS Transaction Debugging course explains how to find Program ProLog Areas (PPAs) storage areas and the new COBOL structures within a CICS transaction dump.

The new COBOL Compiler listing V6 is fully explained.

The attendees will be given a road-map of problem solving and taken through a number of transaction dumps. Data Exceptions and Protections Exception are fully covered, as is a LINK and COBOL Call. The attendee will understand the important of CICS Control Blocks ? EIB, PESA, TCA and the Trace table. The attendee will be able to describe how to use the Program Status Word and the General Purpose Registers to assist in debugging.

What You Can Expect

Enterprise COBOL V6 have dramatically changed how COBOL defines and locates its Working Storage and Linkage Sections. The traditional methods of locating these areas via the Task Global Table are gone. The TGT has been removed.

COBOL has introduced new areas called the PPAs. Program Prolog Areas. There are 4 of them. There is a new Static Map that has also been created. The new COBOL Compiler listing V6 is fully explained.

This CICS/TS Transaction Debugging course explains how to find these storage areas and these new COBOL structures within a CICS transaction dump. Upon completion, attendees will be able to confidently debug transactions dumps, to be more self-sufficient with application problems and to understand the methodologies of dump solving. The attendees will be given a road-map of problem solving and taken through a number of transaction dumps. Data Exceptions and Protections Exception are fully covered, as is a LINK and COBOL Call. The attendee will understand the important of CICS Control Blocks ? EIB, PESA, TCA and the Trace table. The attendee will be able to describe how to use the Program Status Word and the General Purpose Registers to assist in debugging.
