RACF® provides a component trace ability for the R_admin callable service. To activate this trace, start GTF specifying TRACE=USR, and issue the RACF SET TRACE(IMAGE) command. When tracing of IMAGE events is active, the R_admin callable service records a snapshot of the input data it receives in GTF records, including:

• The function-specific parameter list containing segment and field data
• The caller's jobname, ASID, PSW, and ASCB address

It also logs, in a separate record:

• The return code
• The reason code
• The output messages
