Tracing DL/I calls with image capture to test your ODBA program

The DL/I image capture program (DFSDLTR0) is a trace program that can trace and record DL/I calls issued by batch, BMP, and online (IMS DB environment) programs. You can produce calls for use as input to DFSDDLT0.

You can use the image capture program 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 (DL/I test program)

  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. For example, you can use the image capture program with a ODBA application, to produce calls for DFSDDLT0.

• Debug your program

  When your program terminates abnormally, you can rerun the program using the image capture program. The image capture program 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.
