Using AMP=('TRACE=(subparameters)') in the DD card

After completing the steps in Starting the record management trace function, start the R/M trace function as follows:

  1. Place AMP=('TRACE=(subparameters)') on the DD statement of the data set that you want to trace.

The AMP=('TRACE=(subparameters)') specifies to VSAM that you want to trace the control blocks associated with the data set identified by the DD statement. For complete syntax information on the AMP parameter, see the section on coding the DD statement in z/OS MVS JCL Reference.
