CICS DUMP TRANSACTION provides transaction dump generation capabilities in CICS environments. It enables programs to generate transaction dumps, manage dump operations, and handle transaction dump generation for debugging and analysis purposes.
1234567EXEC CICS DUMP TRANSACTION [DUMPID(dump-identifier)] [FROM(data-area)] [LENGTH(data-length)] [RESP(response-code)] [RESP2(response-code-2)] END-EXEC.
Specifies the dump identifier for the transaction dump. This parameter provides a unique identifier for the generated dump.
Specifies the data area containing additional information to be included in the dump. This parameter provides context data for the dump.
Specifies the length of the data area to be included in the dump. This parameter controls the amount of additional data included.
Specifies the response code variable to receive the operation result. This parameter provides error handling and status information.
Specifies the secondary response code variable for additional error information. This parameter provides extended error details when available.
DUMP TRANSACTION captures the current state of the transaction, including program variables, storage areas, and execution context.
The command generates dumps for error analysis, providing detailed information about transaction failures and exceptions.
Debug dumps include comprehensive information for troubleshooting and system analysis purposes.
Performance dumps capture transaction execution details for performance analysis and optimization.

Successful dump generation. The transaction dump has been successfully generated and stored.
Invalid dump identifier. The specified dump identifier is invalid or not supported.
Invalid data length. The specified data length is invalid or exceeds maximum allowed length.
Insufficient storage. There is not enough storage available to generate the dump.
Dump generation failed. The dump generation process failed due to system conditions.
DUMP TRANSACTION has significant system impact, so it should be used judiciously and only when necessary for debugging.
Transaction dumps consume significant storage space, so proper storage management is essential for system performance.
Dump generation should be timed appropriately to avoid impacting critical business operations and system performance.
Always check response codes and handle errors appropriately, especially for storage limitations and system conditions.
Use meaningful dump identifiers and implement proper dump management to ensure effective debugging and analysis.
Minimize dump generation frequency and use appropriate data lengths to reduce system impact and storage usage.
Ensure that sensitive data is not included in dumps and implement proper access controls for dump files.
Imagine you're playing with building blocks and something goes wrong. CICS DUMP TRANSACTION is like taking a picture of all your building blocks exactly as they are when something goes wrong.
The dump identifier is like writing a label on the picture so you can find it later. The picture shows exactly what was happening when the problem occurred, so grown-ups can figure out what went wrong.
Just like taking a picture uses up space on your camera, creating a dump uses up space on the computer, so it's only done when really needed to help fix problems.
Write a program that uses DUMP TRANSACTION to generate a dump with a specific identifier and verify the dump was created successfully.
Create a program that generates dumps when error conditions occur, including relevant error information in the dump data.
Implement a debug dump management system that generates dumps at different processing stages with meaningful identifiers.
