API Trace Facility Messages

This chapter complements the application programming interface (API) trace information presented in Diagnosing Problems with APPC/MVS TPs. Messages for the API trace facility:
  • Report ATBTRACE REXX exec syntax or processing errors
  • Report the status of tracing activity
  • Illustrate conversation data written to the trace data set.

These messages are either returned to the issuer of the ATBTRACE REXX exec, or written to the trace data set. Additional messages related to the API trace facility appear on the operator console; these messages are documented in z/OS MVS System Messages, Vol 3 (ASB-BPX).
