Running image capture as a batch job

To run the image capture program as a batch job, you use the DLITRACE control statement in the DFSVSAMP DD data set.

In the DLITRACE control statement, you specify:

• Whether you want to trace all of the DL/I calls the program issues or trace only a certain group of calls.
• Whether you want the trace output to go to:
  • A sequential data set that you specify
  • The IMS log data set
  • Both sequential and IMS log data sets

If the program being traced issues CHKP and XRST calls, the checkpoint and restart information may not be directly reproducible when you use the trace output with DFSDDLT0.

When you run DFSDDLT0 in an IMS DL/I or DBB batch region with trace output, the results are the same as the application program's results, but only if the database has not been altered.

For information on the format of the DLITRACE control statement in the DFSVSAMP DD data set, see the topic Defining DL/I call image trace in IMS Version 15 System Definition.
