Tracing DL/I calls with image capture for your IMS program

The DL/I image capture program (DFSDLTR0) is a trace program that can trace and record DL/I calls issued by all types of IMS application programs.

Restriction: The image capture program does not trace calls to Fast Path databases.

You can run the image capture program in a DB/DC or a batch environment to:

Test your program
If the image capture program detects an error in a call it traces, it reproduces as much of the call as possible, although it cannot document where the error occurred, and cannot always reproduce the full SSA.
Produce input for DFSDDLT0
You can use the output produced by the image capture program as input to DFSDDLT0. The image capture program produces status statements, comment statements, call statements, and compare statements for DFSDDLT0.
Debug your program
When your program terminates abnormally, you can rerun the program using the image capture program, which can then reproduce and document the conditions that led to the program failure. You can use the information in the report produced by the image capture program to find and fix the problem.
